FREMONT -- Authorities say that a 32-year-old man apparently was drunk, talking on his cell phone and jaywalking when a car struck and killed him on Mission Boulevard near Mayhews Road at 8:03 a.m. Thursday.

Police say that witnesses told them that David DeJesus of Fremont had been celebrating his birthday the previous night and had been drinking heavily.

A preliminary police investigation indicates that DeJesus was attempting to cross the northbound lanes of Mission Blvd in a mid-block crossing during heavy morning commute traffic.

According to police, DeJesus is believed to have been talking on his cell phone when he suddenly crossed in front of a northbound 2001 Audi Coupe which was driven by a 48-year-old Walnut Creek man.

Police say DeJesus sustained major injuries to his lower extremities and fatal injuries to his head.

Police say that although the case is still under investigation, there appears to have been nothing that the driver could have done to avoid the collision.

Anyone who has information about the accident is asked to call the Fremont police traffic services unit at (510) 790-6760.

In a separate incident, 45-year-old Wayne Gonzales of Newark was killed after he was run over by a big-rig after sleeping under the truck's rear tires on the loading ramp of Michael's Arts and Crafts at 39170 Argonaut Way in Fremont about 5:45 a.m. Thursday.
