Two guests at the Montage Resort & Spa in Laguna Beach were killed by gunfire Sunday during a confrontation with police at the door of their hotel room.

The incident occurred shortly before 8 a.m. as police investigated reports of a distraught woman with a gun on the south side of the posh resort.

The woman was in one of the hotel’s bungalows, where she was arguing with a man believed to be her husband.

Officers said they fired into the guest quarters after the woman repeatedly refused to obey their commands. According to authorities, a handgun was found inside the room after the shooting.

But it was unclear whether it was police shots that killed both people. Authorities are looking into several possibilities, including whether the woman shot the man — perhaps during the confrontation with police. It is not know whether the woman had fired any shots.

Police described the man and woman as middle-aged and guests of the hotel. They were withholding their names pending notification of relatives.

The Montage resort, which has 262 rooms and cost $200 million to build, is on the bluffs above the Pacific in South Laguna. Rooms with ocean views go as high as $895 a night, while the bungalows are $2,200 a night.

Investigators searched the bushes for evidence, while hotel staff kept visitors and guests away from the area.

Guests said they were awakened by a hammering sound, which they later learned was gunfire.
