RENTON, Wash. – A man who police say shot and critically wounded a woman inside a movie theater in Renton Thursday night is in custody. The victim was upgraded to serious condition Friday morning.

The shooting happened shortly after 8 p.m. at the Regal Cinemas at The Landing.

Renton police say the suspect, who appeared intoxicated, went to the showing of "13 Hours." Police say the man walked inside the theater with a gun and "accidentally" discharged his weapon, hitting a woman in the theater.

The woman is being treated at Harborview Medical Center in Seattle.

Police believe the suspect initially left the scene right after the shooting, but the man's father called 911 a short time later to turn him in.  The 29-year-old surrendered to police at his family's home in Newcastle.

The suspect told detectives the shooting was an accident that took place when he dropped his gun. The man reportedly said the gun fired when it fell to the ground. He also said he'd been drinking before the shooting.

Renton police said the suspect had a permit to carry a concealed weapon.
