CHP: Party Bus Rollover in Portola Valley Kills Passenger

The California Highway Patrol continued to investigate a fatal party bus crash Monday that killed one passenger in his late 30s on Sunday night and caused the temporary shutdown of northbound Interstate 280 near Portola Valley.

UPDATE: The Santa Clara County Medical Examiner has identified the man killed in Sunday night’s party bus crash as 38-year-old Adam Blomquist of San Francisco.

The driver of the San Francisco-based party bus - a converted Chevrolet Express 3500 - was initially nowhere to be found, according to CHP Officer Art Montiel.

But, four hours later, a man wandering along the highway was found with injuries. That man, later identified by CHP as 43-year-old Jason Quinonez, is now facing a trio of felony charges,  including DUI and manslaughter.
