Car found on rocks of Yerba Buena Island

San Francisco firefighters are trying to determine how an unoccupied car ended up on the rocks of Yerba Buena Island Tuesday morning, a fire department spokeswoman said.

The car was reported at about 7:30 a.m. near the lighthouse on the southeast tip of the island, San Francisco fire spokeswoman Mindy Talmadge said.

Crews determined the car is unoccupied and investigators “are going to try to figure out how it got there,” Talmadge said.

Yerba Buena Island connects the eastern and western spans of the Bay Bridge and also includes a U.S. Coast Guard station.
