Police have stated that John Russell “Rusty” Houser, the man responsible for the shooting of 11 people at a Lafayette, Louisiana screening of the movie “Trainwreck,” purchased the gun he used legally.

“This was slow and methodical,” Gov. Bobby Jindal said. “This was not a single burst.”

The weapon was a Hi-Point .40 caliber semiautomatic pistol with a 10-round magazine. Houser reportedly fired and reloaded the gun during his assault.

“Out of 20 rounds he shot 11 people, but some people suffered multiple wounds,” said Lafayette Police Chief Jim Craig. “One person was shot four times.”

Houser had an scattered record of crimes, including an arson arrest that did not result in a conviction. Despite this, police have stated that he purchased the gun legally from an Alabama Pawn Shop.

“He just didn’t show up on any of the instant background checks,” said Drew Griffin to CNN.
