The search continued Tuesday for whoever fatally shot a juvenile outside an apartment complex in Pomona.
Police received a shots fired call about 7:10 p.m. Monday night in the 1300 block of West Third Street, the Pomona Police Department stated in a news release.
A boy was found at the scene with at least one gunshot wound to the upper body.
Paramedics treated the victim and then transported him to Pomona Valley Hospital, where he was pronounced dead.
The age and identity of the victim have not been released. Neighbors told KTLA the victim lived in a nearby apartment with his parents and siblings.
Video from the scene showed a scooter still standing upright behind the police crime tape.
Investigators have not released any information on the gunman and it was also unclear if the shooter left on foot or in a vehicle.
Police are searching for witnesses or surveillance video that may show the crime.
A motive for the shooting was not known.
"I just heard it man, and it was loud," Kron Night, a family friend, told KTLA. He said by the time he had gone outside to see what had happened, the scene was "mayhem."
"They took an uncle, a nephew, a brother. They took more than just a person’s life,” Night said.
Anyone with information was asked to contact the Pomona Police Department at 909-620-2085. Those who prefer to provide information anonymously can call Crime Stoppers at 1-800-222-8477.
