Police responded to three gun-related incidents last night; in separate cases, two people were wounded by gunfire.

In the first incident, reported at 7:56pm, a 36-year-old man called police after hearing gunfire and seeing an undescribed vehicle speed away from the intersection at 25th and Shotwell streets.

No injuries or property damage were reported, and the suspect reportedly used a handgun.

At 9:44pm, police were dispatched to 22nd & Shotwell after a 26-year-old man who was walking on the sidewalk was shot by an unknown suspect who was in a moving vehicle.

The victim, who was transported to a hospital with non-life-threatening wounds, told police that he was heard a loud pop and “saw a vehicle leave the scene at a high rate of speed” before he realized that he’d been wounded.

In a third incident, officers near the corner of 22nd and Mission streets heard gunfire at 1:10am, and observed 2 male suspects in their twenties fleeing the area in an undescribed vehicle.

A 22-year-old female bystander suffered non-life-threatening wounds and was taken to a hospital.

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.
