A man riding a skateboard was struck and killed Saturday in San Francisco’s Bayview neighborhood, police said.

The victim, whose name was not immediately released, was struck by a white sport utility vehicle while on his skateboard near Third Street and Cargo Way about 9:30 p.m., said Officer Gordon Shyy, a San Francisco police spokesman.

The victim died at the scene.

The driver and the SUV was found shortly after the collision, police said.

“It is possible the driver did not know he struck” the victim, Shyy said, adding the crash may not be a hit-and-run as police had initially reported.
