One person was killed and another was injured Wednesday morning in a shooting that took place inside a Muni train between Forest Hill and Castro stations in the system, said District 7 Supervisor Myrna Melgar. on Twitter.
Melgar said the suspect ran off the train at Castro station and was still at large, but stressed that police were not handling the incident as an active shooter situation.
“We have too many guns out there,” Melgar said in a follow-up tweet. “Too much, too much.”
Melgar told The Chronicle that the shooting was not random and that the alleged shooter and another man were in a heated dispute before the shooting.
“The shooter pulled out a gun and shot the guy he was arguing with,” Melgar said. “The second victim was not involved in the verbal altercation, but was right next to the other victim.”
It was unclear whether the shooting of the second victim, a woman, was accidental, he said. The victim is the one who survived his injuries.
Police are currently interviewing witnesses and have closed the Castro Street station for evidence, Melgar said.
City officials on Wednesday morning urged residents to avoid the area between Castro and Market streets due to police activity and said bus transportation was being arranged to transport people from West Portal to on Embarcadero / Folsom streets.
San Francisco police did not immediately respond to a request for comment.
