A criminal complaint and affidavit accuses a North Dakota man of trying to deceive surveillance video and then bleaching weapons and his clothing after killing four people.

Chad Isaak is charged with four counts of murder in Monday's attack at RJR Maintenance and Management in Mandan, a town near the capital of Bismarck. All four slain were RJR employees.


Investigators said surveillance video shows Isaak entering RJR wearing brightly colored clothing, then leaving in dark clothing after the slayings. They said a search of his home found a knife with bent blade tip, parts of a handgun and clothing all bearing traces of chlorine bleach.

The complaint also says nine bullet casings were found at his house. The victims were believed to have been shot nine times. The victims were also stabbed.

The complaint doesn't give a possible motive.

Meanwhile, the owner of the mobile home park where Isaak was arrested said the suspect "never attracted any attention."

Rolf Eggers said he bought the mobile home park in Washburn last fall and Isaak "came with the park." Eggers said that he didn't know Isaak. He said neighbors never complained about him.

Eggers says he hasn't been contacted by law enforcement.
