Police are searching for whoever fatally shot a man outside a shopping center in the Sun Valley neighborhood of Los Angeles Monday night.

The shooting was reported just before 10 p.m. at the intersection of Laurel Canyon Boulevard and Roscoe Boulevard near the Canyon Plaza Shopping Center.

Officers were redirected to Pacifica Hospital of the Valley about two miles away after learning the victim had been shot and was already there.

Video showed a white van, which was apparently used to transport the victim, parked outside the hospital with its doors open and police tape around it.

The victim, described only as a man in his 20s, was shot once in the chest and was pronounced dead at the hospital, according to the Los Angeles Police Department.

Police are searching for the gunman, who is believed to be a man between 5 feet 10 inches and 6 feet tall. Police said the suspect, who was wearing a light blue medical mask, weighs about 250 pounds and fled in a dark-colored vehicle.

The motive for the shooting was unknown.
