LAFAYETTE, La. - A gunman opened fire at a movie theater in Louisiana on Thursday night, killing at least three person and injuring at least others before shooting himself, officials said.

The shooting took place at the Grand Theatre in the city of Lafayette, said Clay Henry, vice president of operations for Acadian Ambulance.

Henry said eight people were brought to the hospital and that two, including the gunman, were pronounced dead on arrival.

Henry said emergency workers got the call to go to the theater about 7:30 p.m. He did not immediately have any additional information.

Lafayette police say they know the identity of the gunman but are not releasing it at this point.

Police say the 58-year-old white man died of a self-inflicted gunshot.

The shooting happened about 20 minutes into a 7 p.m. showing of the movie "Train Wreck," according to the "The Daily Advertiser" newspaper, which quoted theatergoer Katie Domingue.

"We heard a loud pop we thought was a firecracker," Domingue told the newspaper. Domingue said she saw "an older white man" standing up and shooting down into the theater, but not in her direction.

"He wasn't saying anything. I didn't hear anybody screaming either," Domingue said.

Domingue told the newspaper she heard about six shots before she and her fiance ran to the nearest exist, leaving behind her shoes and purse.
