Four people dead, including child, after gunman targets California office building

The shooting was on the second floor of the building, Amat said.

Police said they were called to the two-storey building on Lincoln Avenue in Orange, south of Los Angeles, at about 17:30 local time (00:30 GMT).

Police Lt. Jennifer Amat says shots were being fired when officers arrived and officers shot the suspect, who was taken to the hospital in unknown condition.

The suspect in the shooting was apprehended and was also transported to the local hospital in critical condition, Amat said.

California Gov. Gavin Newsom tweeted his condolences following early reports of the shooting. He said, "Our hearts are with the families impacted by this awful tragedy tonight".

U.S. Rep. Katie Porter, a California Democrat whose district includes the city of Orange, said on Twitter that she was "deeply saddened". Signs outside indicated a handful of businesses were located there, including an insurance office, a financial consulting firm, a legal services business and a phone fix store.

Paul Tovar told KTLA-TV that his brother owns a business there. "I'm pretty scared and anxious. right now I'm just praying really hard". "It's just such a tragedy for the victims, their families, our community and our police department". Six days later, a man opened fire in a supermarket in Boulder, Colo., killing 10.

The shooting came a little more than two weeks after eight people were shot to death by a gunman who went on a rampage at three Atlanta-area day spas on March 16.

Orange, a city of about 140,000 residents, is located about 30 miles southeast of downtown Los Angeles.
