Police discovered the body of a woman packed in a large container with dry ice in a hotel room as they were serving a search warrant in a cocaine investigation, authorities said.

Detectives found the fully clothed and "well preserved" body late Thursday after arresting a guest at the Fairmont Newport Beach for investigation of selling and possessing cocaine on the hotel grounds, police Sgt. Evan Sailor said Friday.

When they searched Stephen David Royds' room, they found the body inside a Rubbermaid container filled with dry ice, he said.

"It's definitely weird," Sailor said.

An autopsy of the body was "inconclusive" because there was no sign of trauma, and her death did not appear to be a homicide, said Dan Akin, an Orange County supervising deputy coroner.

Police identified the woman as 33-year-old Monique Trepp. It wasn't clear how long she had been dead, Sailor said.

Police were investigating whether Royds was involved in the death. He was held on $30,000 (euro19,500) bail.

Royds, 46, told police he was a resident of Newport Beach, but there was no telephone listing for him. A receptionist at the hotel, a posh complex surrounded by palms, referred inquiries to company spokeswoman Michelle Heston.

"We are working alongside and assisting the Newport Beach police in this investigation but right now it's in their hands ... this is a police matter," Heston said.
