Well known musician Dave Deporis, 40, died Wednesday afternoon from injuries he suffered following a robbery in Oakland's Temescal neighborhood in which he tried to chase down the thief. ABC 7 reports that Deporis was working on his laptop at an outdoor table at a cafe on the 4200 block of Telegraph Avenue yesterday afternoon when a thief snatched his laptop and jumped into a waiting car, reportedly a red Audi. Deporis then gave chase, trying to retrieve his laptop, and caught up to the car on Rich Street. The car then dragged him some distance, leading to traumatic injuries.

As the East Bay Times reports, Deporis was found by police on the 400 block of Rich Street around 12:35 p.m. Wednesday, and was later pronounced dead at the hospital.

Oakland police are offering up to $15,000 for information leading to an arrest in Deporis's killing. Anyone with information is asked to call police at 510-238-3821, or Crime Stoppers at 510-777-8572.
