A "person of interest" who was detained Thursday in connection with four workplace murders in North Dakota earlier this week has now been arrested and charged with the killings, authorities said.
The suspect, identified as Chad Isaak, 44, of Washburn, N.D., lived in a trailer park managed by the Mandan, N.D., the company where the slayings occurred Monday, according to reports. Washburn is about 35 miles north of Mandan.
Police Chief Jason Ziegler, of Mandan, said surveillance video of a vehicle of interest helped lead investigators to Isaak, who was apprehended after a traffic stop Thursday evening.
