Predicting who's at risk for violence isn't easy


CHICAGO (AP) — It happened after Columbine, Virginia Tech, Aurora, Colo., and now Sandy Hook: People figure there surely were signs of impending violence. But experts say predicting who will be the next mass shooter is virtually impossible — partly because as commonplace as these calamities seem, they are relatively rare crimes.


Still, a combination of risk factors in troubled kids or adults including drug use and easy access to guns can increase the likelihood of violence, experts say.


But warning signs "only become crystal clear in the aftermath, said James Alan Fox, a Northeastern University criminology professor who has studied and written about mass killings.


"They're yellow flags. They only become red flags once the blood is spilled," he said.


Whether 20-year-old Adam Lanza, who used his mother's guns to kill her and then 20 children and six adults at their Connecticut school, made any hints about his plans isn't publicly known.


Fox said that sometimes, in the days, weeks or months preceding their crimes, mass murderers voice threats, or hints, either verbally or in writing, things like "'don't come to school tomorrow,'" or "'they're going to be sorry for mistreating me.'" Some prepare by target practicing, and plan their clothing "as well as their arsenal." (Police said Lanza went to shooting ranges with his mother in the past but not in the last six months.)


Although words might indicate a grudge, they don't necessarily mean violence will follow. And, of course, most who threaten never act, Fox said.


Even so, experts say threats of violence from troubled teens and young adults should be taken seriously and parents should attempt to get them a mental health evaluation and treatment if needed.


"In general, the police are unlikely to be able to do anything unless and until a crime has been committed," said Dr. Paul Appelbaum, a Columbia University professor of psychiatry, medicine and law. "Calling the police to confront a troubled teen has often led to tragedy."


The American Academy of Child & Adolescent Psychiatry says violent behavior should not be dismissed as "just a phase they're going through."


In a guidelines for families, the academy lists several risk factors for violence, including:


—Previous violent or aggressive behavior


—Being a victim of physical or sexual abuse


—Guns in the home


—Use of drugs or alcohol


—Brain damage from a head injury


Those with several of these risk factors should be evaluated by a mental health expert if they also show certain behaviors, including intense anger, frequent temper outbursts, extreme irritability or impulsiveness, the academy says. They may be more likely than others to become violent, although that doesn't mean they're at risk for the kind of violence that happened in Newtown, Conn.


Lanza, the Connecticut shooter, was socially withdrawn and awkward, and has been said to have had Asperger's disorder, a mild form of autism that has no clear connection with violence.


Autism experts and advocacy groups have complained that Asperger's is being unfairly blamed for the shootings, and say people with the disorder are much more likely to be victims of bullying and violence by others.


According to a research review published this year in Annals of General Psychiatry, most people with Asperger's who commit violent crimes have serious, often undiagnosed mental problems. That includes bipolar disorder, depression and personality disorders. It's not publicly known if Lanza had any of these, which in severe cases can include delusions and other psychotic symptoms.


Young adulthood is when psychotic illnesses typically emerge, and Appelbaum said there are several signs that a troubled teen or young adult might be heading in that direction: isolating themselves from friends and peers, spending long periods alone in their rooms, plummeting grades if they're still in school and expressing disturbing thoughts or fears that others are trying to hurt them.


Appelbaum said the most agonizing calls he gets are from parents whose children are descending into severe mental illness but who deny they are sick and refuse to go for treatment.


And in the case of adults, forcing them into treatment is difficult and dependent on laws that vary by state.


All states have laws that allow some form of court-ordered treatment, typically in a hospital for people considered a danger to themselves or others. Connecticut is among a handful with no option for court-ordered treatment in a less restrictive community setting, said Kristina Ragosta, an attorney with the Treatment Advocacy Center, a national group that advocates better access to mental health treatment.


Lanza's medical records haven't been publicly disclosed and authorities haven't said if it is known what type of treatment his family may have sought for him. Lanza killed himself at the school.


Jennifer Hoff of Mission Viejo, Calif. has a 19-year-old bipolar son who has had hallucinations, delusions and violent behavior for years. When he was younger and threatened to harm himself, she'd call 911 and leave the door unlocked for paramedics, who'd take him to a hospital for inpatient mental care.


Now that he's an adult, she said he has refused medication, left home, and authorities have indicated he can't be forced into treatment unless he harms himself — or commits a violent crime and is imprisoned. Hoff thinks prison is where he's headed — he's in jail, charged in an unarmed bank robbery.

Winter Storms Spawn Tornadoes Across South













A nasty Christmastime storm system spawned blizzard conditions in some states and at least 15 reported tornadoes in the South, damaging homes, taking out power lines and dangerously snarling holiday travel.


Severe weather swept across the United States during the Christmas holiday, bringing tornadoes and intense thunderstorms to the Gulf Coast, while dumping heavy snow and freezing rain on the Southern Plains.


At least 15 tornadoes were reported today from Texas to Alabama, putting this storm system potentially on track to be one of the largest Christmas day tornado outbreaks on record.


One large tornado was reported in Mobile, Ala., where there are about 19,000 customers without power and 23,429 statewide, according to Alabama Power. Kerry Burns, a Mobile resident originally from Boston, said the storm "sounded like a freight train."


Some buildings in the area, including some churches and a local high school, were reportedly damaged. Ray Uballe, another Mobile resident, said his dad was shaken up.


"He was in his apartment," Uballe said. "He said it sounded like an airplane and then the door flung open and then there was just debris flying."


Douglas Mark Nix, president of the Infirmary Health System, said one of their Mobile hospitals lost power and sustained damage. There were no early reports of injuries to staff or patients.


"We are operating now on generator power," he said. "We do not have substantial damage but we do have a number of windows out and we have some ceiling tiles down, throughout the facility at the main hospital.


"We can run for at least two weeks but I saw power crews out all over the city so I fully expect power to be restored within the next day or so," Nix added.

Winter Weather Causes Holiday Travel Problems Watch Video





At least eight states were issued blizzard warnings today, as the storms made highways dangerously slick heading into one of the busiest travel days of the year.


Oklahoma got about 7 inches of snow all over the state making for treacherous road conditions. ABC News affiliate KOCO-TV in Oklahoma City said the weather was being blamed for a 21-vehicle wreck on Interstate 40, but no one was seriously injured.


Ice accumulation in Arkansas bent trees and power lines, leaving at least 50,000 customers across the state without power. About 10 inches of snow fell on Fayetteville, Ark.


The storms, which first wreaked havoc on the West Coast before moving east, are being blamed for at least one death in Texas.


Investigators in the Houston area told ABC state KTRK-TV in Houston that a young man was trying to move a downed tree that was blocking the roadway when another one snapped and fell on top of him. He was later pronounced dead at a hopsital.


The last time a number of tornadoes hit the Gulf Coast area around Christmas Day was in 2009, when 22 tornadoes struck on Christmas Eve morning, National Weather Service spokesman Chris Vaccaro told ABC News over email.


The deadliest Christmastime tornado outbreak on record was Dec. 24 to 26, 1982, when 29 tornadoes in Oklahoma, Missouri, Arkansas, Tennessee and Mississippi killed three people and injured 32.


The last killer tornado around Christmas, Vaccaro said, was a Christmas Eve EF4 in Tennessee in 1988, which killed one person and injured seven. EF4 tornadoes can produce winds up to 200 mph.


No official word yet on the strength of the string of tornadoes reported today.


While some were preparing for a Christmas feast, others were hunkered down.


More than 180 flights nationwide were canceled by midday, according to the flight tracker FlightAware.com. More than half were canceled by American Airlines and its regional affiliate, American Eagle.


The storm system is expected to continue east into Georgia and the Carolinas Wednesday and could potentially spawn more tornadoes, according to the National Weather Service.


ABC News' Matt Gutman, Max Golembo and ABC News Radio contributed to this report.

Israel says has no proof poison gas used in Syria


JERUSALEM (Reuters) - Israel voiced doubt on Tuesday about the accuracy of Syrian activists' reports that chemical weapons had been used against rebels fighting to topple President Bashar al-Assad.


"We have seen reports from the opposition. It is not the first time. The opposition has an interest in drawing in international military intervention," Vice Prime Minister Moshe Yaalon said on Army Radio.


"As things stand now, we do not have any confirmation or proof that (chemical weapons) have already been used, but we are definitely following events with concern," he said.


The Syrian Observatory for Human Rights gathered activist accounts on Sunday of what they said was a poison gas attack in the city of Homs. The reports are difficult to verify, as the government restricts media access in Syria.


The Observatory, a British-based group with a network of activists across Syria, said those accounts spoke of six rebel fighters who died after inhaling smoke on the front line of Homs's urban battleground. It said it could not confirm that poison gas had been used and called for an investigation.


Syria has said it would never use chemical weapons against its citizens.


Asked about images purported to show patients being treated for possible gas poisoning, Yaalon said: "I'm not sure that what we're seeing in the photos is the result of the use of chemical weapons.


"It could be other things," he said, without elaborating.


On Sunday, senior Israeli defense official Amos Gilad said Syria's chemical weapons were still secure despite the fact that Assad had lost control of parts of the country.


As Syria's southern neighbor, Israel has been concerned about chemical weapons falling into the hands of Islamist militants or Lebanese Hezbollah fighters, cautioning it could intervene to stop such developments.

More local production companies gaining recognition overseas






SINGAPORE: Singapore production companies say they see a growing trend of collaborations with international companies.

The Media Development Authority (MDA) says there are currently 60 production companies that are actively producing broadcast content both locally and abroad.

Channel NewsAsia spoke to two local production houses to find out what makes Singapore attractive as a co-production hub.

The Moving Visuals Company came onto the scene in 1998, during a period when Singapore was trying to promote independent production.

At the same time, many cable television channels were moving their headquarters to the region.

Moving Visuals wasted no time trying to gain a foot in the door by marketing its documentaries overseas.

Its strategy was to focus on factual programming as opposed to drama and sitcoms, which tended to be more localised.

Galen Yeo, CEO of The Moving Visuals Company, said: "When we started, we wanted to focus on factual programming or documentaries as well as kids' programming, primarily because we felt that these genres would travel better. Whereas if you look at certain genres like drama and sitcoms, they tend to be more localised."

It was one of the first production houses to co-produce a programme on the Hungry Ghost Festival with international channel National Geographic and local broadcaster MediaCorp's TV12.

Since then, it has distributed its productions throughout Asia, the United States, Europe and Latin America.

But the company feels more can be done in terms of making headways for more co-productions between local and international broadcasters.

Galen Yeo added: "If I could suggest something for the industry, it would be to be bolder, take more risk, experiment a bit. I think in Asia we sometimes shy away from difficult subjects, or subjects we perceive as being difficult. I think people are more exposed now. And I think we are sort of second guessing and holding ourselves back a little bit sometimes."

Other production houses in Singapore say what attracts overseas players is an Asian story that's packaged for an international audience.

Jocelyn Little, Managing Director of Beach House Pictures, said: "The trend that we are finding is that originally it was more traditional documentaries, with a host or hostess, sort of lifestyle shows. Now it's different. Now everything is more about the character-driven type shows. People want to see real lives, and big characters - which is a trend in the US and Europe, but not so much in Asia yet, but I think it's coming."

Beach House Pictures has produced about 30 overseas projects.

Its latest co-production project is with ABC TV and Northern Pictures to explore the wilderness of Kakadu National Park. And it says the best advice it can give to indie companies starting up is to find strong stories.

Currently, Singapore has five official co-production treaties with Canada, Australia, New Zealand, Korea and China, which facilitated about 20 projects across TV, film and animation. But MDA says there is still untapped potential, which can be harvested from countries like Indonesia and Malaysia.

HC allows transfer of Gayatri Devi's shares to grand children

NEW DELHI: The legal battle over transfer of late Maharani Gayatri Devi's shares in royal family's firms has been decided in favour of her grandchildren, Devraj and Lalitya Kumari with the Delhi high court ordering rectification of share registers of the companies.

Jagat Singh, son of Gayatri Devi and Sawai Man Singh, held 99 per cent shares in firms including Jai Mahal Hotels Pvt Ltd and later died leaving behind a will that his mother would be the owner of all his properties.

Gayatri Devi, who died on 29 July 2009, left a will saying all her properties, including the shares in the firms, would be inherited by her grand children Devraj and Lalitya Kumari.

The transfer of shares in favour of Gayatri Devi's grand children was opposed by other heirs of late Maharaja Sawai Man Singh. They were his (Sawai Man Singh) other sons, Prithviraj Singh, Jai Singh and his maternal grand daughter Urvashi Devi.

Justice Indermeet Kaur, deciding the dispute between members of Rajasthan's royal family, set aside an order of the Company Law Board (CLB) which had refused to direct rectification in share registers of Jai Mahal Hotels Pvt Ltd, Rambagh Place Hotels Pvt Ltd, SMS Investment Corporation Pvt Ltd and Sawai Madhopur Lodge Pvt Ltd.

Earlier, the grand children of Gayatri Devi had moved the CLB for rectification that the shares pertaining to their father and grand mother be transferred to them.

"The CLB returning a finding apposite has committed an illegality which is liable to be set aside. It is accordingly set aside. The order dated March 16, 2011 is set aside; the member register of the companies be rectified in the name of the petitioner group and petitioners i.e. Devraj and Lalitya Kumari be substituted in lieu of Jagat Singh," the court said.

The royal family has key income-generating properties such as Rambagh Place Hotel and Jai Mahal Hotel.

Newtown Christmas: 'We Know They'll Feel Loved'













As residents prepared to observe Christmas less than two weeks after a gunman killed 20 children and six educators at an elementary school, people sharing in the town's mourning brought offerings of cards, handmade snowflakes and sympathy.



Tiny empty Christmas stockings with the victims' names on them hung from trees in the neighborhood where the children were shot. On Christmas Eve, residents said they would light luminaries outside their homes in memory of the victims.



"We know that they'll feel loved. They'll feel that somebody actually cares," said Treyvon Smalls, a 15-year-old from a few towns away who arrived at town hall with hundreds of cards and paper snowflakes collected from around the state.



At the Trinity Episcopal Church, less than 2 miles from the school, an overflow crowd of several hundred people attended Christmas Eve services. They were greeted by the sounds of a children's choir echoing throughout a sanctuary hall that had its walls decorated with green wreaths adorned with red bows.



The church program said flowers were donated in honor of Sandy Hook shooting victims, identified by name or as the "school angels" and "Sandy Hook families."

The service, which generally took on a celebratory tone, made only a few vague references to the shooting. Pastor Kathie Adams-Shepherd led the congregation in praying "that the joy and consolation of the wonderful counselor might enliven all who are touched by illness, danger, or grief, especially all those families affected by the shootings in Sandy Hook."



Police say the gunman, Adam Lanza, killed his mother in her bed before his Dec. 14 rampage and committed suicide as he heard officers arriving. Authorities have yet to give a theory about his motive.



While the grief is still fresh, some residents are urging political activism in the wake of the tragedy. A grassroots group called Newtown United has been meeting at the library to talk about issues ranging from gun control, to increasing mental health services to the types of memorials that could be erected for the victims. Some clergy members have said they also intend to push for change.



"We seek not to be the town of tragedy," said Rabbi Shaul Praver of Congregation Adath Israel. "But, we seek to be the town where all the great changes started."



Since the shooting, messages similar to the ones delivered Monday have arrived from around the world. People have donated toys, books, money and more. A United Way fund, one of many, has collected $3 million. People have given nearly $500,000 to a memorial scholarship fund at the University of Connecticut. On Christmas Day, police from other towns have agreed to work so Newtown officers can have the time off.



At Washington's National Cathedral, the 20 children who were killed also were remembered. Angels made of paper doilies were used to adorn the altar in the children's chapel. They'll be displayed there through Jan. 6.



In the center of Newtown's Sandy Hook section Monday, a steady stream of residents and out-of-towners snapped pictures, lit candles and dropped off children's gifts at an expansive memorial filled with stuffed animals, poems, flowers, posters and cards.



"All the families who lost those little kids, Christmas will never be the same," said Philippe Poncet, a Newtown resident originally from France. "Everybody across the world is trying to share the tragedy with our community here."

New and creative light-ups add festive cheer in Tokyo






TOKYO: It's beginning to look a lot like Christmas in central Tokyo, even if December 25 is not a national holiday in Japan.

Some new and creative light-ups have added festive cheer in the capital.

Tokyo Station's Marunouchi side had a makeover recently to revive its pre-war splendour, before parts of it were destroyed by US bombs in World War Two.

The renovations took more than five years to complete and cost US$593 million.

Much of this side of Tokyo Station is the Tokyo Station Hotel. It was designed in the classic Meiji style by architect Kingo Tatsuno. In 2001, it was designated a national cultural asset.

The station's allure is shining bright, especially now, with a special light-up.

This is the result of a collaboration between classic and hi-tech methods, using projection mapping technology.

Ryotaro Muramatsu, video creator of Tokyo Hikari Vision, said: "The theme is a voyage of the lights. It begins with complete darkness. Light is born. That light expands to all over the world. The lights express the beautiful world of colour. That's the story. I hope people are able to take in that experience."

Well, it seems they are - many visitors were mesmerised.

Other light-ups in the Marunouchi area also drew crowds.

Toshio Nakamura, Head of Tokyo Michiterasu 2012 Committee, said: "Due to Tokyo Station's makeover the entire area is becoming an attraction. We would like very much for that to be noticed."

This installation was created by local school children.

One girl wrote: "Everyone's smile is the source of happiness for tomorrow. Let's laugh."

Starlight walk, as the project is called, is on the way to the Imperial Palace ground.

The display can be enjoyed until December 28th.

And the one million LED lights in champagne gold will adorn the street of Marunouchi NakaDori until February 17.
