Multiple people, including 1 child, shot and killed at California business complex

Four people, including one child, are dead after a suspect opened fire at an Orange, California, business complex on Wednesday evening, NBC News reported.

What are the details?

The carnage occurred Wednesday when a suspect entered a business complex and began shooting around 5:30 p.m.

A fifth victim was shot and taken to a nearby hospital for treatment.

The suspect was also shot and remains hospitalized at the time of this reporting. NBC News reported that both were in critical condition as of Wednesday night.

Orange Police Lt. Jennifer Amat revealed that officers engaged the suspect in an officer-involved shooting.

Amat explained that the business complex houses several offices and added, "It is a situation that was moving from different areas, so it's my understanding it's throughout that area."

Police said that investigators were working to determine a motive.

On Thursday, CNN reported that one firearm was uncovered at the scene of the killing. No officers were injured during the incident.

"I can tell you that we haven't had an incident like this in the city of Orange since 1997," Amat said according to the outlet. "It's just such a tragedy for the victims, their families, our community and our police department."

Wednesday's killing marked the third of its kind in as many weeks. In the month of March alone, a gunman opened fire on several Atlanta spas, killing at least eight people. Just a week later, another suspect opened fire on a grocery store in Boulder, Colorado, killing 10 people.

No other information about the victims was available at the time of this reporting. Officials said the next news conference is set for 10 a.m. local time on Thursday.

In a statement on the deaths, California Gov. Gavin Newson (D) condemned the killing and said that the events were "horrifying and heartbreaking."

"Our hearts are with the families impacted by this terrible tragedy tonight," Newsom tweeted.
