Multiple people were killed and others were injured in a shooting at a rail yard in San Jose, Calif., early on Wednesday, the Santa Clara County Sheriff’s Office said. The assailant was also dead, the authorities said.
Sgt. Russell Davis, a spokesman for the sheriff’s office, said the investigation was centered on 101 West Younger Avenue, the location for a maintenance and dispatch center for the Santa Clara Valley Transportation Authority.
“There are multiple injuries and multiple fatalities in this case,” Sergeant Davis said at a news conference. V.T.A. employees were among the victims, he said.
He added that “the suspect is confirmed deceased,” but did not give any details about the cause of death.
The mayor of San Jose, Sam Liccardo, said in an interview that “at least several people” were killed in the shooting. He said the facility had been evacuated.
“It appears that the suspect’s house is on fire but that there was nobody inside,” Mr. Liccardo said. “There’s a strange connection here between arson and the shooting.”
Gov. Gavin Newsom of California said on Twitter that his office was “in close contact with local law enforcement and monitoring this situation closely.”
Sergeant Davis said that the shooting was reported at about 6:30 a.m. local time, and that the victims included employees of the V.T.A., but he did not have a number. He said he did not know what kind of weapon was used or the motive.
Brandi Childress, a spokeswoman for the V.T.A., said she was informed at 6:45 a.m. local time that there was an “active shooter event.” Employees were on the job at that time, she said.
“It is where we have dispatchers and maintenance,” she said. “They get up early and they are there. That is why the focus is on containing and evacuating employees. It is where we store and maintain all of our trains.”
Earlier on Wednesday, Mr. Liccardo, the mayor, said on Twitter that the shooting “has left several people being treated, but the situation is still being assessed.”
“The shooter is no longer a threat,” he added, “and the facility has been evacuated.”
