In the last 24 hours, two people suffered life-threatening injuries in vehicle collisions—one in Fisherman’s Wharf, and another in the city’s southwest in Merced Heights.

The first incident occurred at 6:55pm when an 82-year-old man who walking on Mason Street near North Point was struck by a driver traveling on Mason Street. The driver remained at the scene and was not arrested, and the victim was transported to a hospital with serious injuries.

In the second crash, which took place this morning around 12:18am, a 20-year-old man who was driving “lost control of his vehicle and crashed into a parking garage,” police reported. The driver was hospitalized in life-threatening condition, and police did not release any additional information.

According to the Department of Health, the Merced Heights crash site is on the city's high-injury network, the 12 percent of city streets where more than 70 percent of the most severe and fatal injuries occur.

Anyone who has information about either of these incidents is encouraged to contact SFPD via the department's anonymous tip line at 415-575-4444, or text TIP411 with "SFPD" at the start of the message.

Here’s why we usually don’t include suspect descriptions in crime reports.
