Driver Arrested and Victim ID'd in Hwy 280 Party Van Crash

The California Highway Patrol arrested the driver of a party van involved in a deadly crash on northbound Interstate Highway 280 near Portola Valley Sunday night.

Jason Quiñonez, 43, drove the converted black Chevrolet Express 3500 that travelled northbound on Highway 280, which went off the roadway and struck a tree south off Alpine Road around 10:50 p.m., CHP Officer Amelia Jack said.

The van overturned in the crash 20 feet away from the freeway and killed Adam Blomquist, 38, of San Francisco, according the Santa Clara County medical examiner's office.

CHP found Quiñonez near the scene with minor injuries and it was initially not clear that he was the driver, according to the CHP. He was taken to Stanford Hospital for minor lacerations and later booked into Santa Clara County Jail on suspicion of felony hit and run, DUI and manslaughter, Jack said.

The CHP has yet to confirm the company that owns the vehicle, she said. The crash remains under investigation.

Initial reports indicated that a second vehicle had been involved, but Jack said that was not the case.

Traffic was blocked on northbound Highway 280 for hours after the accident.
