EDITOR'S NOTE: Following hours of uncertainty during which many media outlets reported the shooter's identity as Ryan Lanza, officials identified the gunman as Adam Lanza. According to WNBC, Adam Lanza was carrying his brothers' identification, which led to the initial misidentification. Adam Lanza's brother, 24-year-old Ryan Lanza, is being questioned by police in New Jersey.
From the AP:
Adam Lanza's older brother, Ryan, 24, of Hoboken, N.J., is being questioned by police, said the first official. Earlier, a law enforcement official mistakenly transposed the brothers' first names.
According to police, Lanza, 24, is suspected of killing 27 people -- including 20 children -- at Sandy Hook Elementary School in Newtown, Conn.
A neighbor of Ryan Lanza's parents in Sandy Hook told The Huffington Post that police are at Lanza's parents house.
The shooter was killed during the rampage and several others were injured.
The identities of the shooting victims has not yet been released.
The gunman was wearing dark clothing, a mask, a bulletproof vest, and was carrying four guns. A cause and manner of death is pending, police said.
Police continue to investigate if there was a second shooter involved.
Unconfirmed reports say that principal Dawn Hochsprung and a school psychologist were killed, according to a parent who claimed to witness part of the attack, CNN reported.
The masked gunman entered the school administration office around 9:40 a.m., about 30 minutes after the school day began. The first 911 call was received by police one minute later.
Investigators said the gunman fired his weapon at least 100 times.
Students inside the building were escorted out in a single-file line. There are about 626 students enrolled in kindergarten through fourth grade classes at Sandy Hook Elementary, with another 46 faculty members, Newtown Patch reported.
Authorities have not commented on whether the deadly encounter was captured on video surveillance.
Friday's shooting comes just two days after a gunman in Oregon shot and killed two people at a crowded Oregon mall. The suspect in that case was identified as 22-year-old Jacob Tyler Roberts. Police say Roberts’ took his own life inside a mall store. Authorities in that case are still piecing together a possible motive.
Sandy Hook Elementary School is closed Friday while police continue to investigate the shooting.

Details On Funeral And Burial Process
The president of the Connecticut Funeral Director's Association said the funeral and burial process for Newtown victims, which began Monday with the separate burials of Noah Pozner and Jack Pinto, who both were six-years-old, is unlike anything he has seen before.
"I've unfortunately seen lots of kids who have died," said Pasquale Forino, 46, who runs Neilan Funeral Home in New London, Conn. "But this truly shakes your foundation to the core, and in a small town like Newtown, they need lots of help to handle this week of burials."
Forino and a group of morticians who have volunteered have driven to Newtown every day since Friday to help tend to families who are grieving and prepare arriving bodies for viewings and burials. The main funeral home in the town, Honan Funeral Home, is handling the process for 11 victims. Of those, Forino said he has worked on three -- all kids.
"It's not about me, it's about the families and victims. But it still affects us," he said. "We do what we can do to take care of the families. We'll deal with our own emotional needs later."

Time to Rise Up and Say 'Enough' to Gun Violence
In the aftermath of the Sandy Hook shooting, a New Jersey columnist urges people and politicians to fight for stronger gun control laws.
"Every time there is a mass shooting, we shake our heads and bemoan the tragic violence. We wonder aloud why our elected officials cannot stanch the flow of weapons. We rue the fact that there are so many troubled individuals out there, desperate for help and poised to commit terrible crimes, for no apparent reason. But nothing ever changes," she writes. "This holiday season, can we all rise up as one and say ENOUGH?"

NIH Study: Only 1/2 Kids In U.S. With Severe Mental Illness Get Treatment
A nationally representative face-to-face survey of more than 10,000 teens ages 13-18 turned up alarming findings about their access to professional mental health care.
Only about one-third of those with any lifetime mental disorder got professional help, and just half of those severely impaired by mental disorders received professional help, the study found. State and federal efforts to increase youth mental health services aren't working, it said. Racial and ethnic minority youth were least likely to get help, the study found.

The controversial Westboro Baptist Church has announced plans to protest outside of the Anne Arundel Circuit Court on Jan 2.—the first day same-sex couples will be able to wed there.

AFT Urges Michigan Gov. Snyder To Veto Gun-In-Schools Bill
American Federation of Teachers President Randi Weingarten and AFT Michigan President David Hecker on Sunday urged Michigan Gov. Rick Snyder Sunday to veto legislation that would allow concealed firearms in schools and other locations.
The tragic massacre at Sandy Hook Elementary School in Newtown, Conn., on Dec. 14, is a “chilling and heartbreaking reminder” that “firearms have absolutely no place in our schools,” they wrote. “Gov. Snyder, please show the kind of leadership that students, families, educators and community members need to be as safe as possible in their schools. You can set an example for Michigan and the nation by taking this small but significant step to reduce gun violence by vetoing S.B. 59.”
