SAN FRANCISCO (CBS SF) — A homeless man sleeping in a San Francisco North Beach underground parking garage was fatally struck by a car early Wednesday, authorities said.

San Francisco police said they received a call around 7 a.m. reporting the incident in the 700 block of Greenwich St.

Arriving officers found man near the entry to an underground parking with injuries stemming from a vehicle collision. He was pronounced dead on scene.

The driver of the vehicle remained at the scene and was cooperating with police.

The garage is located in an area where many of San Francisco’s homeless population find darkened commercial doorways, unlocked vehicles and other hidden nooks to sleep.

A body covered by a blanket at the bottom of the ramp was clearly visible to passing pedestrians.

Police spokesman Robert Rueca said the victim has not been identified. Rueca said the medical examiner is performing an autopsy and police are testing the driver for drugs and alcohol.
