A pedestrian attempting to cross California 67 about two miles south of Poway Road was struck and killed Monday evening by a southbound car, authorities said.
James Martin Florence, 29, of Santee, died at the scene of the 5:15 p.m. accident, San Diego County Deputy Coroner Chuck Bolton said.
William Brownlow, of Lakeside, told authorities he was traveling south at 55 m.p.h. when a pedestrian ran across the roadway in front of his car, California Highway Patrol spokesman Jim Logan said.
"He applied his brakes but he wasn't able to avoid hitting the man," Logan said.
It was not known why Florence was running across the highway, according to Logan.
"There was no evidence he had had car trouble," he said. "We just don't know at this time what he was doing running across the highway."
