HAYWARD -- Investigators on Monday were trying to determine why a San Lorenzo man was in the middle of the road when he was hit and killed by a vehicle on Saturday night, police said.

Bradford Hardie, 58, died when he was hit at 10:23 p.m. on Hesperian Boulevard near West Winton Avenue, Hayward police Sgt. Chad Olthoff said. Emergency personnel arrived to find Hardie lying in the northbound No. 2 lane, Olthoff said.

An early investigation indicates Hardie was running eastbound across Hesperian when the collision happened. Hardie was "several yards" away from the crosswalk when he was hit, Olthoff said.

Investigators were going over the incident, but doesn't appear the driver ever saw Hardie. The driver, who was not injured, cooperated fully with police and Olthoff said alcohol and drugs do no appear to be a factor.

"We don't know why he was in the road," Olthoff said. "It's a very poorly lit area, and there's nothing to indicate there was any brake activity (by the driver) before impact."

Police did not identify the make or model of the vehicle that hit Hardie.

Anyone with information or who may have seen the collision is urged to call Hayward police at 510-293-7099.
