Soon after, the victim, 23-year-old Crisoforo Bello, pounded on a resident's door asking for help and saying he'd been shot or stabbed.
Bello was taken to Loma Linda University Medical Center, where he was pronounced dead.
Investigators say the suspects took Bello's 2003 light gray Ford Taurus. The car is a four-door vehicle, with paper plates and white lettering that says "Unique Auto."
