The suspect accused of killing four people and injuring a fifth at an office complex in Orange, Calif., knew all of the victims both personally and through business, investigators said Thursday, identifying him as 44-year-old Aminadab Gaxiola Gonzalez.
The gunman had chained the gates to the office building, which forced officers responding to the scene Wednesday afternoon to engage with him from the outside, Orange Police Lt. Jennifer Amat said.
Orange County District Attorney Todd Spitzer said Gonzalez, of Fullerton, would be eligible for the death penalty If convicted.
The identities of those killed in the nation’s third mass shooting in just over two weeks are currently being withheld by police, but officials said one was a 9-year-old boy.
The others included a man and two women.
While a specific motive for the shooting remains unknown, they noted that the shooting was “not a random act of violence.”
The building in which they were shot includes a mobile home brokerage and houses several businesses.
The gunman was also critically wounded and hospitalized following the shooting, according to The Associated Press.
In a Facebook Post, the Orange County Police Department said “an officer involved shooting” had occurred.
At least one firearm was recovered at the shooting scene, the Orange County Register reported late Wednesday.
The scene was stabilized by 7 p.m. PT and there was no longer a threat to the public, the Orange Police Department told Fox News.
California’s Democratic Gov. Gavin Newsom tweeted that the killings were “horrifying and heartbreaking.”
“Our hearts are with the families impacted by this terrible tragedy tonight,” he said.
Orange is 30 miles southeast of Los Angeles and home to around 140,000 residents.
Orange police said Wednesday night’s shooting there was the deadliest since 1997, when four state transportation employees were killed in a work yard by a former co-worker, the New York Post reported.
