MANDAN, N.D.—A North Dakota man charged Friday with killing four people at a business that manages the mobile home park where he lives tried to avoid detection by picking up shell casings, changing his clothing, and cleaning a knife and gun with bleach, according to court documents.
Court documents allege that after shooting and stabbing the victims, Chad Isaak, 44, took one of the company’s vehicles to drive about one block, then walked to his own truck parked less than a mile away at a McDonald’s. Authorities traced his steps with help from surveillance video at businesses along the route, the documents say.
