Connecticut school shooter identified as Adam Lanza, suspected of killing 26 (UPDATED)

The shooter suspected of killing 26 people, including 20 children, at a Connecticut elementary school has been identified as Adam Lanza, who died of self inflicted wounds.

A law enforcement official told CNN that Lanza is in his 20s and that law enforcement is already on the scene.

Lanza was killed at the Sandy Hook Elementary School in Newtown, Connecticut. He had entered the school building at 9:40 a.m. Police were called to the scene a minute later, notes The Huffington Post.

Authorities have not released the identities of the victims. There have been unconfirmed reports that principal Dawn Hochsprung and a school psychologist were among the victims.

ABC News has also reported that Lanza’s mother was among the victims.

Investigators say that the suspect fired at least 100 rounds.

Witnesses continue to describe the tragic scene to the media. “I saw policemen -- lots of policemen in the hallway with guns,” 9-year-old Vanessa Bajraliu told the Hartford Courant. “The police took us out of the school. We were told to hold each others' hands and to close our eyes. We opened our eyes when we were outside.”

The incident has caused an uproar on social media as well, with both #PrayForNewtown and #GunControlNow trending on Twitter.

UPDATE: President Obama gave short remarks at the White House and was seen in tears. NBC News is reporting that he has ordered flags to be flown at half staff. There are also reports that another member of Lanza's family was found dead at their New Jersey home.

UPDATE: CNN and the AP are now reporting that it was actually Adam Lanza, 20, who is the suspect. Ryan Lanza is his brother. Reports suggest that Adam had Ryan's ID on him.

UPDATE - 12/15 - 8:17 a.m.: CNN reports that the names of the victims could be released as early as Saturday. It is also being reported that Lanza killed his mother at her Newtown home, where Lanza lived. He then went to the school.

UPDATE - 12/15 - 11:17 a.m.: Lt. Paul Vance of the state police said that they have found "very good evidence" that could answer their questions about the motive, but it is still not known why Lanza killed his mother and people at the school, according to The AP.
