Officers arrested Steven Harry Heath, 60, in connection with the hit-and-run that killed 64-year-old George Michael Black of Pacifica.
Officers responded to the collision in the 4600 block of Montgomery Drive at 1:08 p.m. and found Black on the side of the road. He was pronounced dead at the scene at 1:15 p.m., police said.
