The suspect in Friday's school shooting is now being identified by law enforcement as Adam Lanza (20), whose mother was a teacher at the Connecticut elementary school.

Authorities say the shooting at Sandy Hook Elementary School took place in two rooms, but they are not giving details on exactly how it unfolded. Youngsters and their parents have described teachers locking doors and ordering children to huddle in the corner or hide in closets when shots echoed through the building.

Officials have confirmed that 27 people, including 20 children were killed. Lanza's mother, Nancy Lanza, was subsequently found murdered at her home. Officials say Adam Lanza was found dead shortly after the shootings took place, from what appear to be self-inflicted wounds.

Officials say Lanza's 24-year-old brother Adam Lanza, who officials originally misidentified as the shooter, was being questioned by police Friday afternoon; It is unknown whether or not he was involved.

A 6-year-old told his father that he was in his classroom when a gunman burst in and shot the teacher. Robert Licata says his son "grabbed a bunch of his friends and ran out the door." Licata says the shooter didn't say a word.

Stephen Delgiadice says his 8-year-old daughter heard two big bangs and teachers told her to get in a corner. His daughter is fine.

He says the shooting is alarming because his family always considered Newtown to be the safest place in America.

Seventeen-year-old Mergim Bajraliu heard the gunshots echo from his home and raced to check on his 9-year-old sister at the school. He says his sister heard a scream come over the intercom at one point. And he says teachers were shaking and crying as they came out of the building.

The investigation into the shooting is still underway, and Lanza's motive for carrying out this tragic massacre is still unknown.
