President Obama called for new proposals for reducing gun violence during an address Wednesday. 
 
 He appointed Vice President Joseph Biden to head an inter-agency panel to come up with "a set of concrete proposals by January that I intend to push without delay," Obama said. 
 
 In the wake of the shooting deaths of 20 children and 6 adults at Sandy Hook Elementary School in Newtown on Friday, the issue of gun control, especially assault weapons and high capacity magazines, has been brought to the fore of the national discussion. 
 
 "This is a team that has a very specific task, to pull together real reforms right now," Obama said. 
 
 The panel will include members of the cabinet, Congress and other stakeholders, Obama said. 
 
 "Any single gun law can't solve all these problems," he said. "We'll take a look at mental health, schools. We know issues of gun safety will be an element of it." 
 
 In the past any effort at gun law reform has been viewed as an encroachment of the Second Amendment, Obama said, so he's looking for a thoughtful approach. 
 
 "There's a big chunk of space between what the Second Amendment means and having no rules at all," he said. "That space is what we're going to be working on to see if we can find some common ground." 
 
 Not all gun violence can be prevented, Obama said, "but that can't be an excuse not to try." 
 
 Reform will require Americans from across the political and cultural spectrum to work together. 
 
 "If we're going to change things, it's going to take a wave of Americans … standing up and saying, 'Enough,' on behalf of our kids." 
 
 In addition to reforming laws concerning military-style semi-automatic rifles and high-capacity magazines, Congress should close a loophole that allows gun sales at gun shows without a background check, Obama said. 
 
 He also emphasized the need to improve access to mental health care. 
 
 "We need to make access to mental health care at least as easy as access to a gun," he said. 
 
 "This time, the words need to lead to action." 
 
 Biden was the author of the 1994 crime bill that led to a ban on assault weapons, a ban that Obama noted was supported by all living former presidents at the time, including Ronald Reagan. 
 
 "There's already a growing consensus for us to build upon," Obama said. The majority of Americans already support banning the sale of assault weapons and high-capacity clips, as well as [requiring] background checks before any gun purchases, he said. 
 
 Meanwhile, as detectives continue to comb through evidence and talk to people who witnessed Friday's mass murder at Sandy Hook Elementary School, the state's chief medical examiner Dr. H. Wayne Carver has asked a geneticist at the University of Connecticut to join in his investigation of the killings. 
 
 Carver is awaiting toxicology testing results for gunman Adam Lanza, 20, and information that may help answer the question of why Lanza gunned down 20 first-graders and six women at Sandy Hook. 
 
 "I'm exploring with the department of genetics what might be possible, if anything is possible," Carver said Tuesday. "Is there any identifiable disease associated with this behavior?" 
 
 Carver said he does not know whether Lanza had Asperger's syndrome — a possibility that has been raised — but he said Asperger's "is simply not on the menu, in terms of what is wrong with this kid. Asperger's is not associated with behavior patterns that are violent." 
 
 Determining why Lanza went on a rampage that apparently ended only when fast-arriving police prompted him to kill himself may be difficult. Lanza destroyed a hard drive from his computer, which authorities had hoped would reveal clues about what he did, and he killed his mother as she slept. 
 
 Carver said that Nancy Lanza died of four gunshots to the head from a .22-caliber rifle. She was in bed when her son killed her, and likely still asleep, Carver said. The rifle was left at the house. 
 
 Mary Ellen O'Toole, a retired FBI profiler and behavioral scientist, said seeking an answer in Adam Lanza's biology is worthwhile. 
 
 "I think it's great to consider if there's something here that would help people understand this behavior," O'Toole said. 
 
 There will be other important clues contained in the reports that detectives prepare about the crime scene and their interviews with witnesses, O'Toole said. Some of that information may help behavioral scientists answer the key question: why? 
 
 One thing is apparent from the evidence made public so far, she said. The assault on Sandy Hook Elementary "was not an impulsive act," she said. "This was well thought out." 
 
 The planning could have gone on for days, weeks or months, she said. 
 
 State police Lt. J. Paul Vance has repeatedly described the investigation as a process during which Newtown and state police detectives will peel back the layers of the case. Just how much of the story detectives will finally be able to tell remains unknown, but it will not be a fast process. 
 
 "It's going to take months," Vance said. 
 
 Gov. Dannel P. Malloy has declared Friday a day of mourning and has asked that people observe a moment of silence at 9:30 a.m. He has also asked houses of worship and government buildings with bells to ring them 26 times in honor of the victims. 
 
 "Let us all come together collectively to mourn the loss of far too many promising lives at Sandy Hook Elementary School," Malloy said. "Though we will never know the full measure of sorrow experienced by these families, we can let them know that we stand with them during this difficult time." 
 
 Malloy has also asked governors throughout the nation to join Connecticut "during this time of reflection and mourning." 
 
 "Mourning this tragedy has extended beyond Newtown, beyond the borders of Connecticut, and has spread across the nation and the world," Malloy said. "On behalf of the state of Connecticut, we appreciate the letters and calls of support that have been delivered to our state and to the family members during their hour of need." 
 
 Meanwhile, in Washington, D.C., Connecticut's senators thanked their colleagues for a resolution of condolence and support for Newtown and urged Congress to never let such a tragedy occur again. 
 
 "Criminal and deranged people should not be able to get their hands on firearms,'' said Democrat Richard Blumenthal, who called for "a meaningful and thoughtful debate. .. This is our moment." 
 
 "The Supreme Court has made it clear that government can impose sensible regulation,'' said Blumenthal, who called for new restrictions on high capacity ammunition magazines that enable weapons to quickly fire multiple rounds. 
 
 "What real hunter uses or needs 30-round clips?" 
 
 Independent Joseph Lieberman said, "The question is, 'Can we do anything to stop this from happening again?' " 
 
 "We can prevent this from happening to people again," Lieberman said. "We can certainly prevent it from happening to some people. I have seen some progress. Some colleagues who have been protectors of gun rights are saying things have to change." 
 
 He cited Sen. Joe Manchin, D-W.Va., and Sen. Mark Warner, D-Va. On Monday, in response to the Newtown shootings, Warner said "enough is enough" and called for "rational gun control." 
 
 "I hope we will act," Lieberman said. "There will be no better tribute, no better consolation to the families that lost loved ones." ||||| Police block off a section of Yogananda Street near a house belonging to the mother of a man who opened fire inside a Connecticut elementary school, killing 26 people, including 18 children, Friday, Dec....

 Now the world will always remember him as a mass murderer. The 20-year-old man is believed to have killed his mother, gunned down more than two dozen people, 20 of them children, at a Connecticut grade school and committed suicide. 
 
 He might have suffered from a personality disorder, law enforcement officials said. 
 
 So far, authorities have not spoken publicly of any possible motive. They found no note or manifesto, and Lanza had no criminal history. Witnesses said the shooter didn't utter a word. 
 
 Adam Lanza attended Newtown High School, and news clippings from recent years show him on the honor roll. Joshua Milas, a classmate who was in the technology club with Lanza, said that he was generally a happy person but that he hadn't seen him in a few years. 
 
 "We would hang out, and he was a good kid. He was smart," said Milas, who graduated in 2009. "He was probably one of the smartest kids I know. He was probably a genius." 
 
 The tech club held "LAN parties" _ short for local area network _ in which students would gather at a member's home, hook up their computers into a small network and play games. Gloria Milas, Joshua's mother, hosted one of the parties once. 
 
 She recalled a school meeting in 2008 organized by the gunman's mother to try to save the job of the club's adviser. At the meeting, Milas said, Adam Lanza's brother Ryan said a few words in support of the adviser, who he said had taken his brother under his wing. 
 
 "My brother has always been a nerd," Ryan Lanza said then, according to Milas. "He still wears a pocket protector." 
 
 Catherine Urso, who attended a vigil Friday evening in Newtown, Conn., said her college-age son knew the killer and remembered him for his alternative style. 
 
 "He just said he was very thin, very remote and was one of the goths," referring to a style of dress noted for a heavily black wardrobe. 
 
 Authorities say Adam Lanza shot his mother at their home before driving her car to Sandy Hook Elementary School and _ armed with at least two handguns _ carried out the massacre, officials said. 
 
 A third weapon, a .223-caliber rifle, was found in the car, and more guns were recovered during the investigation. 
 
 Investigators were trying to learn as much as possible about Lanza and questioned his brother, who is not believed to have any involvement in the rampage. 
 
 Ryan Lanza, now 24 and living in Hoboken, N.J., was being questioned, a law enforcement official said. He told authorities that his brother was believed to suffer from a personality disorder, the official said, speaking on condition of anonymity because he was not authorized to speak on the record about the unfolding investigation. 
 
 The official did not elaborate, and it was unclear exactly what type of disorder Adam Lanza might have had. 
 
 Ryan Lanza had been cooperative and was not under arrest or in custody, but investigators were still searching his computers and phone records. The brother told law enforcement he had not been in touch with Adam since about 2010. 
 
 Adam Lanza and his mother, Nancy, lived in a well-to-do part of Newtown, a prosperous community of 27,000 people about 60 miles northeast of New York City. 
 
 Lanza's parents filed for divorce in 2008, according to court records. His father, Peter Lanza, lives in Stamford, Conn., according to public records, and he reportedly works as a tax director for General Electric. 
 
 Lanza's aunt Marsha Lanza, of Crystal Lake, Ill., said her nephew was raised by kind, nurturing parents who would not have hesitated to seek mental help for him if he needed it. 
 
 If her son had needed counseling, "Nancy wasn't one to deny reality," she said Friday. Marsha Lanza said her husband had seen Adam as recently as June and recalled nothing out of the ordinary. 
 
 Lanza said she was close with Nancy Lanza and had sent her a Facebook message Friday morning asking how she was doing. Nancy Lanza never responded. 
 
 Nancy Lanza's mother was too distraught to speak when reached by phone at her home in Brooksville, Fla. 
 
 "I just don't know, and I can't make a comment right now," Dorothy Hanson, 78, said in a shaky voice as she started to cry. She said she hadn't heard anything official about her daughter and grandsons. She declined to comment further and hung up. 
 
 A law enforcement official speaking on condition of anonymity said investigators believe Adam Lanza attended Sandy Hook school several years ago but appeared to have no recent connection to the place. 
 
 At least one parent said Adam Lanza's mother was a substitute teacher there. But her name did not appear on a staff list. And the law enforcement official said investigators were unable to establish any connection so far between her and the school. 
 
 An official who spoke on condition of anonymity said it was not clear that Adam Lanza had a job, and there was no indication of law enforcement interviews or search warrants at a place of business.

– Stories about Connecticut shooter Adam Lanza have a familiar theme: He was a smart, quiet, polite kid who was was socially awkward and gave no sign this might happen. Samples of coverage about the 20-year-old, who attended the same elementary school where the rampage took place: Hartford Courant: Ex-classmate Kateleen Soy recalls him as "painfully shy" and a "little hard to talk to," but adds, "I wanted people to know he wasn't always a monster. He became one, but he wasn't always that way." Another, Andrew Lapple, recalls: "He was always carrying around his laptop holding onto it real tight. He walked down the halls against the wall almost like he was afraid of people. He was definitely kind of strange but you'd never think he'd do something like this." Associated Press: "Family and friends remember Adam Lanza as many things—intelligent, nerdy, goth, remote, thin." AP says police officials think he might have had some kind of personality disorder. Ex-classmate Joshua Milas from Newtown High School: "We would hang out, and he was a good kid. He was smart. He was probably one of the smartest kids I know. He was probably a genius." Danbury News-Times: "A woman who lives near the Lanza family said Lanza was a 'reserved' and shy youth who appeared to be 'troubled.'" Reuters: Tim Arnone, who went to school with Lanza at Sandy Hook Elementary and at Newtown High School, said they were in the AV-club together, "the nerdiest club in the school." He said Lanza was "driven hard" by his parents, who divorced a few years ago, to do well in school. His mom in particular "pushed him really hard to be smarter and work harder in school." A local landscaper adds that she was an avid gun collector who took him target shooting.
