SAN FRANCISCO (KRON) — The San Francisco Police Department released images of a person of interest in Wednesday’s Muni shooting. The shooter killed one person and injured another Wednesday morning before fleeing from the Castro Station.

A 27-year-old man was pronounced dead at the scene, SFPD said. A 70-year-old man was taken to Zuckerberg San Francisco General hospital with non-life-threatening injuries. The suspect remains at large.

SFPD investigators received video of the incident and released still images of the person of interest, which can be seen above. SFPD is asking the person to come forward and speak with investigators.

According to a statement by Supervisor Myrna Melgar, the suspect and victim were in a heated argument before the shooting. Witnesses heard approximately 3-4 gunshots.

Muni service between the Castro and West Portal stations was stopped for several hours following the shooting. The Castro station reopened around 2:00 p.m.

SFPD Public Information Officer Kathryn Winters said the shooting appears to be an isolated incident and did not seem to target the LGBTQ community.
