California – The incident happened around 3 p.m. near Chrysler and Bendix, according to the Irvine Police Department.
Several people reported hearing multiple shots.
The male victim was found in the driver’s seat of his truck.
Officers pulled him out and tried to render aid but was ultimately pronounced dead at the scene. His identity has not been released.
It’s unknown if the victim was followed to the industrial park or if the suspect was lying in wait, but police say this does not appear to be a robbery and the UPS driver was targeted.
Video from AIR7 HD showed a police canopy set up next to a UPS truck as officers canvassed the area for evidence. The immediate area was roped off by yellow crime scene tape.
Police say that area would be a place where the UPS driver would normally take his breaks after making deliveries.
Authorities say the suspect remains on the loose. The gunman was described by investigators as a man wearing a black shirt, a black hat and a black mask.
A vehicle was seen leaving the area at the time of the shooting that authorities are working to track down.
Police will remain on scene for several hours due to the investigation.
Authorities urge anyone who may have seen anything suspicious in the area around 3 p.m. to call IPD at (949) 724-7200.
