A 44-year-old Washburn man has been arrested in connection with Monday morning’s quadruple homicide at RJR Maintenance and Management in Mandan.
Chad Isaak is facing four counts of Class AA Felony murder.
According to Mandan Police Chief Jason Ziegler, many hours of video surveillance were reviewed by investigators and a suspect vehicle was identified. Further investigation led to McLean County Sherriff’s Office locating the vehicle in Washburn. McLean County Deputies conducted a traffic stop on the suspect vehicle and detained Isaak while a search warrant was executed on the vehicle. Evidence discovered on Isaak and in the vehicle provided probable cause to place Isaak under arrest for the murders.
