The Santa Clara County Coroner’s Office is investigating the death, and a spokeswoman said Friday that authorities had not yet confirmed his identity.

Chopper 5 video Thursday afternoon showed CHP investigating an earlier injury crash on northbound Highway 17 with a single overturned car before coming across the second incident involving multiple vehicles and a downed tree.

The two accidents shut down lanes in both directions for hours, snarling traffic on Highway 17. Authorities were able to reopen all northbound lanes at about 7 p.m.

A spokesman for the CHP did not immediately return a call asking for more information.
