A man opened fire inside the Newtown, Conn. elementary school.
The shooter, identified by the police as Adam Lanza, 20, was first mistakenly identified as his older brother Ryan (24) of Hoboken, N.J., who was being questioned.
According to the Hartford Courant, Lanza's mother body was found in her house in Newtown, less than 5 miles from the school (location on the right of the map).
Adam Lanza allegedly forced his way into the school and shot 20 children aged 6 and 7, and six adults before turning the gun on himself.
