Two shootings occurred less than a mile apart in San Francisco Tuesday night and early Wednesday morning, leaving a 17-year-old with life-threatening injuries, police said.

Around 3:20 a.m. Wednesday, officers responded to a ShotSpotter activation in the 100 block of Holladay Avenue in Bernal Heights.

When officers arrived, there was no victim at the scene. Investigators later learned that a 17-year-old boy had suffered multiple gunshot wounds to the torso and his friends had taken him to San Francisco General Hospital.

His injuries were listed as life-threatening, police said. The assailant is still at large.

Hours earlier, about 7:15 p.m. Tuesday, police responded to shots fired in the Mission District at 26th Street and Treat Avenue. The victim, a 21-year-old man, told officers he didn’t see anything — he just heard the sound of gunfire and felt something hit his lower back, police said.

He was taken to a hospital, where he was in stable condition Wednesday, police said.

There were no descriptions given for the shooters in both incidents, police said.
