Person of interest detained in ND killings probe

MANDAN, N.D.

A person of interest has been detained in the investigation into the killings of four people at a North Dakota business, police said Thursday evening.

The Mandan Police Department said in a news release that investigators are following up on a tip that led them to Washburn, about 35 miles north of Mandan. The department did not release further information.

Deputy Chief Lori Flaten confirmed earlier Thursday that a search conducted Wednesday in a field about half a mile from the business was related to the investigation. She said state and local police at the scene were “looking for potential evidence,” but she didn’t elaborate.
