A 28-year-old female motorcyclist was hospitalized with life-threatening injuries last night after a collision at California and Laguna streets in Lower Pacific Heights. The incident occurred around 9:35pm. 

The woman was traveling eastbound on California Street when she made contact with the front end of a westbound vehicle making a left turn onto Laguna. The driver of the vehicle, a 63-year-old man, was uninjured in the crash, but the woman sustained a traumatic brain injury and multiple broken bones, and remains hospitalized in life-threatening condition.
