SAN DIEGO, CA — A 6-year-old boy was killed Saturday when he was struck by a hit-and-run vehicle while riding his bicycle in Pacific Beach.

The crash occurred at 3:45 p.m. Saturday as the boy was riding eastbound on the south sidewalk of 1540 Pacific Beach Drive when he crossed the west alley of 4000 Ingraham Street, said San Diego police Officer Jose Perales.

A 32-year-old woman was eastbound on Pacific Beach Drive and made a right turn into the Ingraham Street alley, where she struck the boy on his bicycle, Perales said.

“The driver stopped for several seconds before accelerating rapidly southbound in the alley,” he said. “As she proceeded forward, the driver ran over the 6-year-old male who had been knocked off his bicycle from the initial collision. The driver then fled the scene.”

It was unclear if the boy had been riding by himself or was being accompanied.

He was taken by ambulance to a hospital, where he was pronounced dead, said the officer.

The vehicle driven by the woman was later located in National City, although police did not disclose how it was found. The woman was then taken into custody, Perales said. Her name was not immediately released.

Alcohol was not a factor in the crash, he said.

The investigation into the crash continued, he said.
