Five people died including a police deputy in a mass shooting that took place in California’s Kern County.

Deputy Phillip Campas and Deputy Dizander Guerrero, members of the Sheriff’s Department’s SWAT team, were shot while approaching the house where the gunman was barricaded, authorities said.

The deputies were trying “to extricate the victims inside, believing that they might still be alive,” a visibly shaken Youngblood said during a news conference.

“We believed from the information we received from 911 calls, and the open line in the house, that there were people alive in there that needed to be rescued,” Youngblood said.

“I believe we were correct in that assumption. That required a SWAT entry, probably the most dangerous thing we do.”

“It looks like a domestic violence situation. There was a restraining order,” Youngblood said, adding that the shooting underscores how “serious” domestic violence is and “how a restraining order is not bulletproof. Our hearts are broken because of the loss of a star in our organization.

We also have three other victims we are mourning from the city of Wasco.”
