Authorities received a call about 12:17 a.m. reporting multiple shots fired in the 1300 block of Columbia Drive, Glendale Police Department Sgt. Dan Suttles said. Officers arrived to find the garage door of the home open and a man down in the driveway. The man was pronounced dead at the scene, Suttles said. Inside the home, officers found two more bodies. The victims were black men between the ages of 20 and 50, the Police Department stated in a news release. “Apparently there was some gunfire and now we have three deceased people,” Suttles said. Investigators have launched a homicide investigation and do not believe the shooting was part of a murder-suicide. Police have no suspect description and no witnesses who saw the shooting, Suttles said. “It’s very, very rare to have three individuals killed at one time and no witnesses,” he said. The sergeant described the neighborhood as a “small residential area.” Investigators do not believe there was an immediate threat to the public. “We think this is something that is isolated to this residence,” he said. A motive for the shooting was unknown. Anyone with information can contact the Police Department at 818-548-4911. Those who wish to remain anonymous may call Crime Stoppers at 800-222-8477.
