Video: Connecticut shooting: Gunman forced his way into school, say police Lt. Paul Vance says the gunman was not voluntarily let into Sandy Hook Elementary School in Newtown. Audio from radio calls made by the first officers on the scene suggests that he may have forced his way in by either breaking the glass doors or shooting his way past the security system. Authorities confirmed the shooter, believed to be 20-year-old Adam Lanza, shot a relative before driving to the school. Unconfirmed reports suggest he had killed his mother at their family ome before then drove her car to Sandy Hook Elementary School on Friday morning and shot 20 children, six adults and himself. Lt Vance says the medical examiner is still working on identifying the victims, but said there was "very good evidence" to explain the motives behind the massacre.
