A man opened fire Thursday night at a movie theater in Lafayette, La., killing one person and injuring at least nine others before turning the gun on himself, authorities said.

Acadian Ambulance Service told NBC News that two people were dead at the scene. Police said they believed one of them was the gunman.

“We believe the scene is safe at this time,” Sgt. Kyle Suarez told NBC News.

Nine other people were injured, according to the ambulance service. Their conditions weren’t immediately available.

Katie Domingue told The Daily Advertiser newspaper that “an older white man” began shooting about 20 minutes into the movie.

“He wasn’t saying anything,” Domingue said. “I didn’t hear anybody screaming, either.”

Keifer Sanders told MSNBC TV that he was in another theater when “the screen went black,” alarms sounded and the audience was shepherded out the emergency exit.

Sanders said police were telling people the gunman committed suicide.

Louisiana State Police, University of Louisiana-Lafayette police, the FBI and the Bureau of Alcohol, Tobacco, Firearms and Explosives were assisting local police. Gov. Bobby Jindal said he was on his way to the scene.
