Around 5:20 a.m., 42-year-old male crossed Power Inn Road at Florin Road against the light and was struck by a northbound vehicle that had a green light, according to the CHP. Poor visibility from fog is believed to have been a factor. Speed and alcohol reportedly did not contribute to the crash.
As the offices recorded each death: direct deaths were caused by the weather itself, indirect ones by something it set in motion.
