Alejandro Castro Flores of Escondido was heading east on the rural road in southeastern San Diego County when his 1999 Chevrolet S-10 veered across a center divider line shortly after 5:30 p.m. Sunday, according to the California Highway Patrol.
The pickup truck sideswiped an oncoming 2005 Nissan Altima, then collided head-on with a 2005 Nissan Sentra, CHP public-affairs Officer Kevin Pearlstein said.
Flores died at the scene of the wreck. The driver of the Sentra, a 33-year-old Chula Vista woman, suffered a broken foot. The 48-year-old Gardena man behind the wheel of the Altima was uninjured.
Investigators suspect that intoxication may have played a role in the accident, Pearlstein said.
