SAN FRANCISCO (CBS SF) —  A jogger was struck and killed by a Golden Gate Transit bus on San Francisco’s Van Ness Avenue Thursday morning, a police spokesman said.

The collision was reported around 6:15 a.m. at Van Ness Avenue and Lombard Street, San Francisco police spokesman Officer Gordon Shyy said.

The jogger, a woman in her 50s, was taken to San Francisco General Hospital and was pronounced dead about an hour later.

The vehicle involved in the collision was a Golden Gate Transit bus, according to transit agency spokeswoman Priya Clemens.

The bus was turning left from Lombard onto Van Ness when it struck the jogger, Clemens said.

She said the bus driver is “obviously shaken up” and that he is one of the agency’s “most senior drivers with an excellent safety record.”

The collision remains under investigation by police and the jogger’s name is not yet being released.
