“Four people, including a 9-year-old boy, were killed in a shooting at a business complex in Orange, California, on Wednesday evening, officials said.

“A fifth victim, a female, was shot and taken to a hospital, as was the suspect, police Lt. Jennifer Amat said. Both were in critical condition.

“Police said officers arrived at an active shooting scene at about 5:30 p.m. and officers engaged “in an officer-involved shooting,” Amat said. The suspect suffered a gunshot wound, but it is not known whether it is was self-inflicted.

“Of the adults killed, a woman was found on an upstairs outdoor landing, Amat said at a news conference on Thursday. A man was found in an office building and another woman was found in a separate office building.”
