20 Children Killed at Conn. Grade School, 7 Adults

Twenty children died today when a heavily armed man invaded a Newtown, Conn., elementary school and sprayed staff and students with bullets.

The gunman, identified as Adam Lanza, 20, was found dead in the school.

Lt. Paul Vance said 18 children died in the school and two more died later in a hospital. Six adults were also slain, bringing the total to 26.

In addition to the casualties at the school, Lanza's mother Nancy Lanza was killed in her home, federal and state sources told ABC News.

According to sources, Lanza shot his mother in the face, then left his house armed with at least two semi automatic handguns, a Glock and a Sig Sauer, and a semi automatic rifle. He was also wearing a bullet proof vest.

Lanza drove to Sandy Hook Elementary School and continued his rampage, killing 26 people, authorities said. He was found dead at the school. It appears that he died from what is believed to be a self inflicted gunshot wound. The rifle was found in his car.

In the early confusion surrounding the investigation, federal sources initially identified the suspect as Adam's older brother Ryan Lanza, 24. He is being questioned by police.

LIVE UPDATES: Newtown, Conn., School Shooting

"Evil visited this community today," Gov. Dan Malloy said at a news conference this evening.

First grade teacher Kaitlin Roig, 29, locked her 14 students in a class bathroom and listened to "tons of shooting" until police came to help.

"It was horrific," Roig said. "I thought we were going to die."

She said that the terrified kids were saying, "I just want Christmas…I don't want to die. I just want to have Christmas."

A tearful President Obama said there's "not a parent in America who doesn't feel the overwhelming grief that I do."

The president had to pause to compose himself after saying these were "beautiful little kids between the ages of 5 and 10." As he continued with his statement, Obama wiped away tears from each eye.

He has ordered flags flown as half staff.

The alert at the school ended when Vance announced, "The shooter is deceased inside the building. The public is not in danger."

The massacre prompted the town of Newtown to lock down all its schools and draw SWAT teams to the school, authorities said today. Authorities initially believed that there were two gunmen and were searching cars around the school, but authorities do not appear to be looking for another gunman.

It is the second worst mass shooting in U.S. history, exceeded only by the Virginia Tech shooting in 2007 when 32 were killed before the shooter turned the gun on himself. Today's carnage exceeds the 1999 Columbine High School shooting in which 13 died and 24 were injured.

The Newtown shooting comes three days after masked gunman Jacob Roberts opened fire in a busy Oregon mall, killing two before turning the gun on himself.

Today's shooting occurred at the Sandy Hook Elementary School, which includes 450 students in grades K-4. The town is located about 12 miles east of Danbury.

State Police received the first 911 call at 9:41 a.m. and immediately began sending emergency units from the western part of the state. Initial 911 calls stated that multiple students were trapped in a classroom, possibly with a gunman, according to a Connecticut State Police source.

Lt. Paul Vance said that on-duty and off-duty officers swarmed to the school and quickly checked "every door, every crack, every crevice" in the building looking for the gunman and evacuating children.

A photo from the scene shows a line of distressed children being led out of the school.

Three patients have been taken to Danbury Hospital, which is also on lockdown, according to the hospital's Facebook page.

Rep. Loretta Sanchez’s 2012 Christmas card: Fiscal cliff, Gretzky in heaven

Here it is, ladies and gentlemen — your Rep. Loretta Sanchez Christmas card for 2012!

(Courtesy of the Office of Rep. Loretta Sanchez)
Over the past decade, the California Democrat’s wacky holiday greetings have drawn a cult following. “I’ve seen them being sold on eBay,” the congresswoman told us.

(Courtesy of the Office of Rep. Loretta Sanchez)
Nice topical theme this year! “The ‘fiscal cliff’ is a very serious situation, so we didn’t want to make light of it,” she said. “But sometimes a chuckle makes things a lot easier.” (Last year’s card tipped a hat to Occupy Wall Street and all that 99 percent talk: “May the joy of the holidays occupy 100 percent of your heart.”)

That’s husband Jack Einwechter dancing with her. Sanchez’s late beloved cat Gretzky, the star of so many cards over the years, is represented inside the card, a halo over his furry head. “Of course — Angel Gretzky,” she said. “We keep Gretzky every year because he has so many followers.”

EU leaders upbeat on euro future after deal on banks, Greece

BRUSSELS: EU leaders debated the euro's future in a bullish mood Thursday after deals on banks and Greece, despite fears that political uncertainty in Italy could cause new worries for the single currency.

As video showed the bloc's 27 leaders smiling and joking with each other at the beginning of a two-day summit, EU President Herman Van Rompuy said leaders should aim to cap a triumphant week that began with the European Union picking up the Nobel Peace Prize.

"We started the week well in Oslo. Let's finish it well here in Brussels with a further positive outcome," Van Rompuy said.

"The worst is now behind us, but of course much still needs to be done," he added as the leaders began deliberations on how to make the 17-nation eurozone more stable after a crippling three-year crisis.

The hero of the day was Italy's Prime Minister Mario Monti, hailed for tough reforms that have brought Italy back from the brink of financial collapse but who announced last weekend he would be stepping down.

"Confidence has been returning in Italy's capacity to solve problems," said European Commission chief Jose Manuel Barroso. "Let me praise Mario Monti and his government for this."

Jitters over Italy's political situation loomed over the summit, after Monti said he would soon step down and former leader Silvio Berlusconi indicated he might run for a fourth term.

But on the sidelines of the talks, Berlusconi hinted he might not put himself forward, telling Belgian television channel VRT that he had "so much to do" outside politics.

At the talks, leaders will debate a report drawn up by Van Rompuy that proposes steps towards greater economic integration in the eurozone, eventually with a common "fiscal capacity" and binding reform commitments.

Following on the heels of a summit only last month that collapsed over the EU's seven-year budget, the atmosphere was noticeably brighter after ministers sealed much-heralded agreements on supervising big banks and aid to Greece.

Greek Prime Minister Antonis Samaras exclaimed that "Grexit is dead", meaning the prospect of Greece leaving the euro currency area was no longer possible after ministers released bailout funds to avert bankruptcy.

After a buy-back programme designed to reduce Greece's debt mountain, Eurogroup head Jean-Claude Juncker said a first payment of 34.3 billion euros ($44.7 billion) would be flowing to Athens "as early as next week."

This instalment would go to help recapitalise Greece's crisis-wracked banks, to be followed by another 14.8 billion euros in the first quarter of next year.

An ecstatic Samaras, who has pushed through painful reforms demanded by creditors often in the face of violent protest, told reporters: "Greece is back on its feet. The sacrifices of the Greek people have not been in vain."

"Today is not only a new day for Greece, it is indeed a new day for Europe," he added.

"It is flying. It is happening"

Hours before the Greece deal, ministers charged the European Central Bank with monitoring banks with assets of more than 30 billion euros, or equal to 20 percent of a state's economic output from March 2014.

The agreement, which German Chancellor Angela Merkel said "cannot be valued highly enough", is the first step on the path towards a banking union and clears the way for EU bailout funds to recapitalise struggling banks directly.

Merkel called the move a "big step towards more reliability and trust in the eurozone."

The new Single Supervisory Mechanism (SSM) for the eurozone -- which Britain and Sweden will not take part in -- will mean the ECB directly supervising some 200 of the biggest banks out of the estimated 6,000 eurozone lenders.

ECB chief Mario Draghi hailed the accord as "an important step towards a stable economic and monetary union, and towards further European integration".

More excitedly, Barroso said: "You remember, when we spoke about this some time ago, people said it will not fly. It is flying. It is happening."

Merkel voiced some satisfaction as she looked back on a year of seemingly endless crisis summits, damaging market volatility and, at times, near break-up of the eurozone bloc.

"All in all, I want to state at the end of 2012 that we have achieved a lot. It was a very heavy year in terms of work but it was also a year in which we managed to make big progress," said the leader of Europe's biggest economy.

The head of the European Parliament, Martin Schulz, however complained that workers' rights had not been taken sufficiently into account.

"As the representatives of the people, we are annoyed that the social pact that we asked for has not been included in the report drawn up by Mr Van Rompuy," Schulz told reporters.

Govt seeks Trai's opinion on cable monopolies

NEW DELHI: The government has sought broadcast regulator Trai's views to prevent monopolistic operations by cable operators and multi-system operators, expressing concern that it might have serious implications in terms of competition, pricing and healthy growth of the cable TV sector in the market.

In a statement, the information and broadcasting (I&B) ministry said, "It has been observed that cable TV distribution is virtually monopolized in some states as operation of the entire cable TV network is dominated by a single entity. At present, there are no restrictions on the issue of accumulation of interest in terms of market share in a city, district, state or country by individual MSOs and LCOs in the cable sector."

MSOs and cable operators are free to operate in any area of their choice after obtaining registration from the ministry. "It is felt that such monopolies may not be in the interest of consumers and may have serious implications in terms of competition, pricing and healthy growth of cable TV sector in that market," the ministry said.

The ministry has requested Trai to provide its recommendations on whether "in order to ensure fair competition, improved quality of service, and equity, should any restriction be imposed on MSOs/LCOs to prevent monopolies/accumulation of interest? If yes, what restrictions should be imposed and what should be the form, nature and scope of such restrictions?" The regulator will also explore the necessity of amending the Cable Television Networks (Regulation) Act, 1995.

MSOs and cable operators are required to be registered with local post offices to be able to operate in the permitted areas of registration. However, as per recent amendments in the Cable Television Networks (Regulation) Amendment Rules 2012, it has become mandatory for MSOs to register with the I&B ministry to operate.

Global Checkup: Most People Living Longer, But Sicker

If the world's entire population went in for a collective checkup, would the doctor's prognosis be good or bad? Both, according to new studies published in The Lancet medical journal.

The vast collaborative effort, called the Global Burden of Diseases, Injuries, and Risk Factors Study 2010, includes papers by nearly 500 authors in 50 countries. Spanning four decades of data, it represents the most comprehensive analysis ever undertaken of health problems around the world.

It reveals that, globally, we're living longer but coping with more illness as adults. In 1990, "childhood underweight"—a condition associated with malnutrition, measles, malaria, and other infectious diseases—was the world's biggest health problem. Now the top causes of global disease are adult ailments: high blood pressure (associated with 9.4 million deaths in 2010), tobacco smoking (6.2 million), and alcohol use (4.9 million).

First, the good news:

We're living longer. Average life expectancy has risen globally since 1970 and has increased in all but eight of the world's countries within the past decade.

Both men and women are gaining years. From 1970 to 2010, the average lifespan rose from 56.4 years to 67.5 years for men, and from 61.2 years to 73.3 years for women.

Efforts to combat childhood diseases and malnutrition have been very successful. Deaths in children under five years old declined almost 60 percent in the past four decades.

Developing countries have made huge strides in public health. In the Maldives, Bangladesh, Bhutan, Iran, and Peru, life expectancy has increased by more than 20 years since 1970. Within the past two decades, gains of 12 to 15 years have occurred in Angola, Ethiopia, Niger, and Rwanda, an indication of successful strategies for curbing HIV, malaria, and nutritional deficiencies.

We're beating many communicable diseases. Thanks to improvements in sanitation and vaccination, the death rate for diarrheal diseases, lower respiratory infections, meningitis, and other common infectious diseases has dropped by 42 percent since 1990.

And the bad:

Non-infectious diseases are on the rise, accounting for two of every three deaths globally in 2010. Heart disease and stroke are the primary culprits.

Young adults aren't doing as well as others. Deaths in the 15 to 49 age bracket have increased globally in the past 20 years. The reasons vary by region, but diabetes, smoking, alcohol, HIV/AIDS, and malaria all play a role.

The HIV/AIDS epidemic is taking a toll in sub-Saharan Africa. Life expectancy has declined overall by one to seven years in Zimbabwe and Lesotho, and young adult deaths have surged by more than 500 percent since 1970 in South Africa, Botswana, Zambia, and Zimbabwe.

We drink too much. Alcohol overconsumption is a growing problem in the developed world, especially in Eastern Europe, where it accounts for almost a quarter of the total disease burden. Worldwide, it has become the top risk factor for people ages 15 to 49.

We eat too much, and not the right things. Deaths attributable to obesity are on the rise, with 3.4 million in 2010 compared to 2 million in 1990. Similarly, deaths attributable to dietary risk factors and physical inactivity have increased by 50 percent (4 million) in the past 20 years. Overall, we're consuming too much sodium, trans fat, processed meat, and sugar-sweetened beverages, and not enough fruits, vegetables, whole grains, nuts, fiber, calcium, and omega-3 fatty acids.

Smoking is a lingering problem. Tobacco smoking, including second-hand smoke, is still the top risk factor for disease in North America and Western Europe, just as it was in 1990. Globally, it's risen in rank from the third to second leading cause of disease.

Rice Withdraws From Sec. of State Consideration

Image Credit: Evan Vucci/AP Photo

UN Ambassador Susan Rice has withdrawn her name from consideration for Secretary of State, saying the criticism surrounding her comments on Benghazi had become an “irresponsible distraction.”

“I am fully confident that I could serve our country ably and effectively in that role,” Rice wrote in a letter to President Obama today. “However, if nominated, I am now convinced that the confirmation process would be lengthy, disruptive and costly – to you and to our most pressing national and international priorities.”

Read Susan Rice’s letter to President Obama

“That trade-off is simply not worth it to our country,” she added.

Rice has been criticized by Republicans for her response to questions on the Sunday talk shows shortly after the terrorist attack on the U.S. consulate in Benghazi killed four Americans.

“The position of Secretary of State should never be politicized,” Rice wrote. “As someone who grew up in an era of comparative bipartisanship and as a sitting U.S. national security official who has served in two U.S. Administrations, I am saddened that we have reached this point, even before you have decided whom to nominate. We cannot afford such an irresponsible distraction from the most pressing issues facing the American people.”

Sources tell ABC News that even before Rice withdrew her name from consideration to be Secretary of State earlier today, Senator John Kerry, D-Mass., had emerged as the leading contender, with the president convinced he would be the better Secretary of State.

The president is all but certain to nominate Kerry, sources say, though no official decision has been made.

The position of Secretary of Defense is not as far along in the process, but sources say former Sen. Chuck Hagel, R-Neb., seems to have an edge right now over other possible candidates such as former undersecretary of defense for policy Michelle Flournoy and deputy Secretary of Defense Ashton Carter.

The CIA director slot, sources say, will go to either acting director Michael Morrell or White House counterterrorism adviser John Brennan.

President Obama, who publicly defended Rice on several occasions, has accepted her decision to remove her name from the running.

“I have every confidence that Susan has limitless capability to serve our country now and in the years to come, and know that I will continue to rely on her as an advisor and friend,” Obama said in a written statement. 

“While I deeply regret the unfair and misleading attacks on Susan Rice in recent weeks, her decision demonstrates the strength of her character, and an admirable commitment to rise above the politics of the moment to put our national interests first,” he said. “The American people can be proud to have a public servant of her caliber and character representing our country.”

Two Republican members of Congress who had adamantly opposed Rice’s potential nomination both reacted quickly.

Sen. Lindsey Graham, R-SC., tweeted, “I respect Ambassador Rice’s decision.” And a spokesperson for Sen. John McCain, R-Ariz., wrote, “Senator McCain thanks Ambassador Rice for her service to the country and wishes her well. He will continue to seek all the facts surrounding the attack on our consulate in Benghazi that killed four brave Americans.”

Will there be a by-election in Punggol East?

SINGAPORE: While the by-election in Hougang earlier this year was called under identical circumstances - where an incumbent Member of Parliament (MP) vacated his seat because of an extramarital affair - political analysts TODAY spoke to were split over whether it could be used to gauge if and when a by-election will be held in Punggol East, following the resignation of its MP, Mr Michael Palmer.

The Hougang by-election was called about three months after former MP Yaw Shin Leong was expelled from the Workers' Party for "indiscretions in personal life", after rumours had emerged about an affair with a fellow party member.

Institute of Policy Studies Senior Research Fellow Gillian Koh said any by-election could follow a timeline and process that is similar to the recent Hougang by-election.

Dr Koh said: "The public and residents in the SMC (Single Member Constituency) may expect the same kind of resolution as the Hougang case even if (the constituency) is supported by the massive PAP machinery and voted the PAP in the majority in the General Election last year."

Former Nominated MP Zulkifli Baharudin felt that a by-election would be called in less than three months.

"(The PAP) would make a quick decision. Looking at the way they have been handling this whole matter, I think they would get on with it as fast as possible, as there is no point in dragging this," he said.

But Assistant Professor Eugene Tan, a law lecturer at the Singapore Management University, disagreed.

It could be much longer - in about six to 12 months - before one might be held, given the packed political calendar in the months ahead, he said.

Asst Prof Tan, who is also a Nominated Member of Parliament, noted that for example, Parliament is set to discuss a White Paper on population and Budget 2013 in the first few months of next year.

He added: "Generally, the longer the time interval is between the vacating of the seat, and the by-election, the better it is (for the party)."

In fact, there is no certainty that a by-election will be called in Punggol East, Asst Prof Tan pointed out.

There is the question of "whether the People's Action Party wants to create a political norm, to call for a by-election whenever a seat is being vacated", he added.

Should a by-election be called in Punggol East, it will be the fourth election held in the country in a short span of time - after the General Election and Presidential Election last year, and the Hougang by-election earlier this year.

'Robu, surely you've not forgotten...!'

Hoye gelo. Over. But he hasn't gone - Robu shesh hoye jayeni. He is there and he will be there... in all our tomorrows.

Ravi Shankar's sitar taught the world what Indian Classical ragas are all about. Indian music is eternal - saswat. It is universal - world music. Robu, Ananda, (Uday) Shankar, they don't go away. But there are times when I feel like asking God: Why am I still around? I ask God - although I've never met him - because today I have lost a brother, a friend, a colleague in the demise of one person: Ravi Shankar.

In 1930, I was merely 11 when my father Akshay Nandi took me to Paris for an International Colonial Exhibition. Baba used to bring out a magazine named Matri Mandir where writers like Ashapurna Devi, Mankumari Devi, Radharani Devi were all regulars. In the Indian pavilion Baba had mounted an exhibition of our handiwork - the term 'handicraft' had yet to add value to such work. One day we were surprised by the visit of some Indians in suits and trousers who were introduced to us as "Uday Shankar" and "Timir Baran". Now, although I'd heard a lot about Uday Shankar and his work with Indian dance, I was taken aback as I was expecting someone old with snow-white, flowing beard a la Rabindranath.

While leaving he invited us to his house where his mother and brothers were staying. That's where I first met Robu. A year younger to me, he came out of a room, still trying to tuck in the string of his pajamas! From the very first moment I got a brother and a friend. His mother took me under her wings: she draped me in a sari and tied my long hair. I spent the weekend with them and was dropped back on a Monday. Later that week we went to watch Uday Shankar perform with his troupe - and was left speechless.

Long 81 years have passed since that visit to Paris. I did not return to France until this May, when I went to Cannes for the screening of the restored Kalpana. Meanwhile my father, who initially said 'no' to my dancing as I was good at writing, agreed to send me to Almora where Uday Shankar proposed to me, we got married, we made Kalpana, Ananda and Mamata were born....

Through all these years, Robu has remained a brother, friend, companion. We played together, we danced together, we made music together, we read Ramayan together, we would share ideas and thoughts. That's why, every time we met, at whatever age, he'd say, "Boudi, you remember that day...?" or "Boudi, surely you haven't forgotten that time...!"

One day in Almora Shankar was concerned. "Where've you been?" he asked Robu and me. We'd gone out for a walk in the jungles and lost track of time! Sometimes he'd be dushtu, naughty. A photographer wanted to take a photo of us together. He suddenly posed like Krishna with his flute. I responded by becoming Radha. I think this is the best encapsulation of our friendship. I used to challenge him: "Tell me, do you have a more affectionate bond with any other person?" No, he'd agree, no one else was friend and sister rolled into one.

Robu always said, he had two gurus - Uday Shankar and Baba Allauddin Khan. From his elder brother Robu had mastered his showmanship: he knew what, and how much, to play, where. Uday Shankar loved Western music but he gave Robu to Baba's care. When he married Annapurna, I decked her up in bridal finery although I was still not married. Years later, one day Annapurna was complaining that Robu is deviating from Baba's signature music. "That's all!" I said. "You've married the younger brother, I, the elder. If you find five faults in Robu, I can find seven. Instead, why don't you see the qualities that have endeared him to all?"

In Uday Shankar's troupe there were 360 Indian instruments though we toured with only 130! Robu learnt the strength of each of these. That is why he could create Vrinda Gaan (Choral Music) for AIR. In Kalpana, there's a sequence where he used dekchi, handi, pitcher etc to create the robust 'noisy' music of street kids.

Ravi Shankar could understand Uday Shankar's talent, and he understood Robu's. This came out when we staged Samanya Kshati to mark Tagore Centenary in 1961, at Nehru's behest. "Got it!" Shankar had said soon as I recited the poem. But the subject was difficult to translate into a dance drama. When the Queen of Kashi sets afire some jhuggis to warm herself after a bath in the Ganga, the king banished her from the palace until she rebuilds them. But how to show realisation dawning on the repentant queen? How to translate Tagore's introspective lines into movement when Shankar never used words?

That's where Robu's music stepped in. The minute I recited the line Robu, whose sitar was playing the queen's dialogue while Ali Akbar's sarod was speaking for the king, stopped in his track. "Repeat it exactly as you spoke!" he urged. I did so, and he played the bols in his gayaki-ang, giving birth to a masterpiece.

Although in its sunset years, Robu and his brothers were born into a zamindar family where it was routine for them to be served six kinds of meat with 16 bottles of alcohol evening. I came from a rural background where we routinely had milk and flattened rice (chira) for breakfast. But we never had any gulf in our lives because we were knit together by the values and common ideals of eternal India.

That bond will continue beyond our lives.

(As told to Ratnottama Sengupta)

Gold “Mining” Termites Found, May Lead Humans to Riches

Want to know if you're literally sitting on a gold mine? Get some termites, a new study suggests.

New experiments in West Australia reveal that termites "mine" and stockpile the precious metal while they're collecting subterranean material for their nests.

For the study, entomologist Aaron Stewart, with Australia's Commonwealth Scientific and Industrial Research Organisation, and colleagues took samples from several termite nests and compared the nest material to nearby soil samples from varying depths.

By using a mass spectrometer—an instrument that measures molecules' chemical makeup—they discovered that the termite nests were richer in gold than termite nests farther away from the metal, Stewart said in an email. (Also see "Battling Termites? Just Add Sugar.")

"That social insect colonies can selectively accumulate metals from their environment has been known for some time," Robert Matthews, a professor emeritus of entomology at the University of Georgia, noted by email.

"Some have even suggested that ant and termite nests could be analyzed productively when searching for potential mining sites for precious metals" such as gold, he said.

Those are Stewart's thoughts exactly. Gold deposits are usually hidden a few meters below the surface, making them tough for people to locate. But insects could essentially act as indicators of this buried treasure, said Stewart, whose study appeared recently in the journal Geochemistry: Exploration, Environment, Analysis.

"Drilling is expensive. If termites can help narrow down the area that needs to be drilled, then exploration companies could save a lot of money."

Termites Worth Their Waste in Gold?

In a related study published in 2011 in PLoS ONE, Stewart and his colleagues set out to find if termites, like many animals, accumulated metals within their bodies—potentially another way to pinpoint valuable mineral deposits.

Just as mammals accumulate calcium to maintain bones, some insects stockpile zinc and magnesium to harden their exoskeleton, particularly their jaws. Metals such as zinc act to reinforce those body parts.

But insects are also really good at excreting metals they do not need or that are toxic to them, Stewart noted. For example, insects shed metal either during molting or as tiny stones, much like kidney stones in humans. (Also see "Rock-Eating Bacteria 'Mine' Valuable Metals.")

When Stewart started to investigate insect excretory systems, he made a "fascinating" discovery that certain organs in the termite's excretory system contain varying amounts of metals-hinting at unknown processes going on inside the termite. That's important, he said, because it means that termite waste is a "driving force" for how metals get redistributed in an ecosystem.

Mall Shooter Quit Job, Was Going to Hawaii

In the days before he stole a semiautomatic weapon and stormed into an Oregon shopping mall, killing two people in a shooting spree, Jacob Roberts quit his job, sold his belongings and began to seem "numb" to those closest to him.

Roberts' ex-girlfriend, Hannah Patricia Sansburn, 20, told ABC News today that the man who donned a hockey mask and opened fire on Christmas shoppers was typically happy and liked to joke around, but abruptly changed in the week before the shooting.

Roberts unleashed a murderous volley of gunfire on the second floor of the Clackamas Town Center on Tuesday while wearing the mask and black clothing, and carrying an AR-15 semiautomatic weapon and "several" magazines full of ammunition. He ended his barrage by walking down to the first floor of the mall and committing suicide.

"I don't understand," Sansburn said. "I was just with him. I just talked to him. I didn't believe it was him at all. Not one part of me believed it."

She said that in recent weeks, Roberts quit his job at a gyro shop in downtown Portland and sold all of his belongings, telling her that he was moving to Hawaii. He had even purchased a ticket.

She now wonders if he was really planning to move.

"He was supposed to catch a flight Saturday and I texted him, and asked how his flight went, and he told me, 'oh, I got drunk and didn't make the flight,'" she said. "And then this happens... It makes me think, was he even planning on going to Hawaii? He quit his job, sold all of his things."

Roberts described himself on his Facebook page as an "adrenaline junkie," and said he is the kind of person who thinks, "I'm going to do what I want."

Roberts, who attended Clackamas Community college, posted a picture of himself on his Facebook page firing a gun at a target. His Facebook photo showed graffiti in which the words "Follow Your Dreams" were painted over with the word "Cancelled."

Sansburn said the pair had dated for nearly a year but had broke up over the summer. Throughout their relationship, she had never seen him act violently or get angry.

"Jake was never the violent type. He didn't go out of his way to try to hurt people or upset people. His main goal was to make you laugh, smile, make you feel comfortable. I never would have guessed him to do anything like this ever," she said.

"You can't reconcile the differences. I hate him for what he did, but I can't hate the person I knew because it was nothing like the person who would go into a mall and go on a rampage. I would never associate the two at all."

The last time she saw him, which was last week, he "seemed numb," and she didn't understand why, she said.

"I just talked to him, stayed the night with him, and he just seemed numb if anything. He's usually very bubbly and happy, and I asked him why, what had changed, and said 'nothing.' He just had so much he had to do before he went to Hawaii that he was trying to distance himself from Portland," Sansburn said.

Sansburn said the last message she sent Roberts was a text, asking him to stay, and saying she didn't want him to leave. He replied "I'm sorry," with a sad face emoticon.

Police are still seeking information about what Roberts was doing in the days leading up to the shooting. They said today they believe Roberts stole the gun he used in the rampage from someone he knew. They have searched his home and his car for other clues into his motive.

Read ABC News' full coverage of the Oregon Mall Shooting

Clackamas County Sheriff Craig Roberts said earlier today on "Good Morning America" that he believes Roberts went into the mall with the goal of killing as many people as he could.

"I believe, at least from the information that's been provided to me at this point in time, it really was a killing of total strangers. To my knowledge at this point in time he was really trying, I think, to kill as many people as possible."

Sansburn said she has not talked to police.
