Laguna Beach, Calif. ? A couple fatally shot by police at a luxury oceanfront resort had checked in under false names and with a bagful of ammunition for their semiautomatic handgun, officials said.

Authorities discovered the ammunition after the shooting Sunday at the Montage Resort & Spa that killed Kevin Christie Park, 49, and Joni Lynn Park, 48.

Police were called to the resort for a report of a domestic dispute and fired into the couple’s $2,200-a-night bungalow after they refused to drop a handgun, said police Sgt. Jason Kravetz.

“It may not have been domestic violence, but that’s how we were called to the scene,” Kravetz said. “Usually in a domestic violence (case) the woman doesn’t go out and try to shoot at other people.”

Several 911 callers said a naked woman was running around the hotel waving a gun, authorities said. She was distraught and periodically threatened people with the gun, Kravetz said.

By the time officers arrived, the woman had retreated to the bungalow, where she and her husband took turns pointing the gun at five officers through a sliding glass door, Kravetz said.

Two officers opened fire after the woman refused to drop the gun, Kravetz said.

The couple had checked in using false names and addresses, and they paid in cash, Kravetz said. Police searched the room and found a loaded semiautomatic handgun, extra ammunition and boxes of documents.

The Parks’ daughter Christie, 23, told the Los Angeles Times that her parents checked into the resort to discuss a “business-type thing.”

“They were just people that got pushed a little too far with things they couldn’t clear up legally and financially,” Christie Park said of her parents.
