Four teenage students were shot in the shared parking lot of two San Francisco high schools, and one of the students is in critical condition, authorities said.
In a statement released Wednesday morning, SFUSD Interim Superintendent Myong Leigh said the suspects were not students and had targeted their victims.
District education officials described the shootings as "an isolated incident outside of the school building" and involving "outsiders".
The shooting was reported at June Jordan School for Equity around 3:15 p.m, according to police.
Officers immediately began searching for the shooter, "thinking that suspect might still be in the school shooting", he said. Police weren't aware whether they were students, and no one has been taken into custody.
They seemed to have targeted a female student, who now has life-threatening injuries, police have said.
School district officials had tweeted that June Jordan high school would open for classes on Wednesday. School employees called the SFPD for assistance unsure of the whereabouts of the shooter (s) and if the shooting was still in action or not. Two male victims suffered non life-threatening injuries.
He told the San Francisco Chronicle that he heard at least six "pops" before students and faculty began running in every direction.
Another victim walked into the Bayview police station. They were targeting a student who attends June Jordan School for Equity "for reasons that are presently unclear", according to the interim superintendent.
