Six people were injured in a shooting at an Oakland school on Wednesday, authorities said.
The victims, all adults, were treated in local hospitals, Mayor Libby Schaaf said on Twitter.
Two were in critical but stable condition, and a third person was listed as stable at a local trauma hospital, said James Jackson, CEO of Alameda Health System.
A fourth person suffered what Oakland Police Department assistant chief Darren Allison described as non-life-threatening injuries. Two others would be discharged from another hospital, he said.
Further details about the victims were not immediately available.
The shooting happened shortly before 1 p.m. at a campus of four schools, including a middle and high school, in the city’s Eastmont Hills neighborhood, Allison told reporters.
The victims had “some ties” to Rudsdale, one of the schools. Schaff previously said gunfire broke out at Sojourner Truth, a K-12 independent college that is also on campus.
Victims were found in the school, Allison said.
Allison has not identified a possible motive or suspect. Authorities are looking for one gunman, although others may have been involved, he said.
Schaaf said the incident “shakes the soul” and that “the unfettered access to firearms in our country is unforgivable.”
The shooting is the second at an Oakland school in less than a month. Authorities said a 12-year-old shot a 13-year-old at Madison Park Academy on August 29, injuring the boy.
The shooting came like the California city of nearly half a million struggles with increasing gun violence. On Tuesday, Oakland Police Chief LeRonne Armstrong a plan revealed aimed at mitigating that violence.
