Police: Gunman 'Forced His Way Into' Sandy Hook Elementary School

NEWTOWN, Conn. (TheBlaze/AP) -- Connecticut State Police say a gunman who massacred 26 children and adults at an elementary school before committing suicide forced his way into the building.

Lt. Paul Vance said Saturday morning that the suspect was not voluntarily let into Sandy Hook Elementary School in Newton and instead "forced his way into the school."

Authorities say 20-year-old Adam Lanza shot his mother on Friday, drove her car to Sandy Hook Elementary School in Newtown, and shot 20 children, six adults and himself.

Vance said all the victims have been positively identified and authorities were preparing to release a formal written list of names and birth dates.

Vance said crime scene investigators have discovered "very good evidence" that could lend insight into Lanza's motive for the shootings, though did not describe what the evidence was.
