Investigators are asking for the public’s help in identifying a suspect who shot and killed a 23-year-old man on Oct. 14 at the Comedy Store in West Hollywood.

Police are following leads and developing theories but have not determined a motive, said Lt. Steve Jauch, with the Los Angeles County Sheriff’s Department’s Homicide Bureau.

The shooting occurred at approximately 12:49 a.m. as people congregated on the club’s front patio at 8433 Sunset Blvd. An African American man, who witnesses said was wearing a hooded sweatshirt, walked by and opened fire. The victim, identified as Richard James, was struck multiple times. Jauch said James was from the East Coast but declined to be more specific.

“He was in Los Angeles and was just a patron of the club,” Jauch said. “We cannot confirm why he was singled out.”

The victim was taken to Cedars-Sinai Medical Center, where he was pronounced dead. No one else was injured.

The Comedy Store was closed the night after the shooting and reopened the following day. Jauch said he is not aware of any other problems at the club before or after the shooting, and he said investigators believe it was an isolated incident.

“I know it caused a lot of alarm, but we don’t want anybody to be discouraged about attending [The Comedy Store]. It’s just an unfortunate incident,” Jauch said.

Anyone with information is urged to contact investigators with the sheriff’ department’s homicide bureau at (310)890-5500.
