Ian David Long

Ian David Long is a 28 yr old USMC veteran from Newbury Park, a town inside the Thousand Oaks city limits. And a perpetrator of the November 2018 Thousand Oaks, CA at the Borderline Bar and Grill.

His gun, a Glock 21 .45 caliber handgun, was reportedly purchased legally. A neighbor of Long claimed that he suffered from posttraumatic stress disorder as a result of his time in the military, and that they had "no idea what he was doing with a gun". Prior to the shooting, Long had been living with his mother.
