Someone sneaked into the home of a police officer facing child sex abuse complaints and got into a locked room that authorities hadn't searched.

It's not clear what, if anything, was taken from the room of Sgt. Maurice Martinez's house while a patrol officer was posted outside the residence, police Capt. Patrick Stewart said. The person apparently had a key to the room.

Martinez was arrested Wednesday. Investigators were searching his house in south Oklahoma City Thursday when they encountered a dead-bolted door inside.

Rather than break down the door, they took a break for the night. When they resumed the search Friday, the door was found unlocked.
