The San Francisco Police Department is looking for the owner of a white car, saying that its occupants might have witnessed a crash that killed an elderly pedestrian Saturday night.

SFPD spokesperson Sergeant Michael Andraychak says that the collision occurred at around 11:30 p.m. Saturday night at Lake Merced Boulevard and Font Street, at the edge of the SF State campus.

Andraychak says a 77-year-old woman was crossing Lake Merced Blvd when she was struck by a 56-year-old Millbrae resident behind the wheel of a Dodge pickup truck.

Police did not immediately provide further details on the collision, including if the woman was in the crosswalk at Font and Lake Merced, and, if so, if it was she or the driver who was crossing with the signal.

Andraychak says that the driver "remained at the scene and is cooperating with the investigation" and that "impairment does not appear to be a factor." However, he says that "Investigators believe that another vehicle, a two door white car, was traveling on Lake Merced Blvd. at the time of the collision and the occupants may have witnessed the incident."

The possible witnesses did not stop, however, hence the police search to get their account of the collision.

Andraychak says that the SFPD Traffic Collision Investigation Unit is still looking into the case, and is hopeful that members of the public might come forward to assist in their inquiry. The occupants of that car are asked to contact the TCIU at 415-553-1641 or 415-553-9516. They, or anyone else with information on the case, can also contact the SFPD's anonymous tip line at (415) 575-4444, or Text a Tip to TIP411 and begin the text message with SFPD.

As I finished writing this report, news of a second fatal pedestrian collision in SF broke, this time at Octavia Boulevard and Market Streets.

According to KRON 4, a pedestrian was killed as they was crossed the street inside a crosswalk in front of the Octavia on-ramp to 101. The collision occurred shortly before 4:30 a.m. Monday, KRON reports, when the driver of a car "spun out and hit them."

KRON reports that the on-ramp was closed until 4:50 "while authorities investigated the incident." As of publication time, additional information on the crash was not available.
