Lafayette’s Grand Theatre on Johnston Street is expected to remain a closed crime scene until at least Monday, as police this weekend evaluate the evidence they have collected since Thursday’s mass shooting.

Cpl. Paul Mouton, Lafayette Police spokesman, said Saturday morning that no new information was available on how Lafayette shooter John “Rusty” Houser was able to legally purchase a gun in 2014 at a pawn shop in Alabama despite his documented history with mental illness. A Georgia judge committed him to psychiatric treatment against his will in 2008, the Associated Press has reported.

Mouton said police are continuing to scrutinize Houser’s phone records and social media posts as they try to connect the dots explaining how he came to be in Lafayette, and why he killed two women and injured nine others during a Thursday showing of “Trainwreck.”

“We don’t see any kind of common ground as to why he was here in Lafayette, other the fact that he’s a drifter,” Mouton said.

Most of the items shooting victims left behind on Thursday have now been collected as evidence, and Mouton described the scene in the movie theater as quiet and somber. He said police are eager to turn the building back over to the Grand, but he said that do not have an exact timeframe for how long that will take.

Police will now review evidence, including videos of the crime scene. Mouton said police are also still trying to interview some witnesses and those who were injured in the shooting.

More details about the shooter will be released next week, Mouton said.
