A "person of interest" has been detained by law enforcement after four people were found dead at a property management company in North Dakota, police said. The victims were discovered around 7:30 a.m. Monday at RJR Maintenance and Management Company in Mandan, just across the Missouri River from Bismarck, where officers had responded to a medical call at the facility. Police on Thursday said that investigators are following up on a tip that led them to Washburn, roughly 35 miles north of Mandan. Mandan Police Chief Jason Ziegler previously said the killings were "very specific" to the victims who were at the crime scene.
