The CHP said in a crash report that its initial investigation indicates that the deputy was “presumably experiencing vehicle trouble” and walked into a traffic lane on the right side of the six-lane northbound 605 Freeway, between South Street and Artesia Boulevard.
The crash was at 2:45 p.m. Saturday.
The other driver, a 54-year-old man from Buena Park, stayed at the scene and cooperated with investigators, the CHP said in a crash report.
Neither agency released his name Sunday.
“Initial statements obtained at the scene indicate the deputy walked onto the traffic side of the vehicle and was struck by a motorist traveling north in the right lane,” according to a CHP crash report.
Paramedics rushed the deputy to an area hospital, where he later died from his injuries, the CHP said.
