FULLERTON, Calif. Two people were stabbed at a Fullerton movie house during the screening of a horror film on Sunday night. Police are still seraching for the suspect.

The victims, who reportedly did not know each other, were sitting in separate areas of the same theater when they were attacked around 7:30 p.m. at the AMC Theater on Lemon St., Fullerton police Sgt. Eric Halverson said.

The stabbings took place approximately 45 minutes into the showing of “The Signal,” an R-rated suspense/horror film. The suspect, who was described as a white male, fled out of one of the back doors, he said.

“The suspect is still outstanding,” Fullerton police Sgt. Jason Schoen said early Tuesday.

The assailant was described as a heavy set white man in his late to mid 20s, 5 feet 10 inches tall, with black hair.

Investigators reviewed surveillance tape from the theater but the video was of poor quality, Schoen said.

One of the victims was hospitalized with a stab wound to the arm, which also punctured one of his lungs, but he was expected to survive, Schoen said.

The other victim suffered a non-life threatening stab wound to the arm, he added.

The victims did not know each other or the attacker, he said.

Police believe the attacker may be the same individual who had been kicked out of the theater that same day — an intoxicated man who was very disruptive during a movie, Schoen said.

“We believe he (the assailant) is the same subject that had been removed from the theater earlier that day,” Schoen said. “We’re not positive but there are similarities in the descriptions of the subjects.”
