A judge has set $1 million cash bond for a North Dakota man accused of killing four people, citing the "heinous nature" of the crimes.

Chad Isaak, a 44-year-old chiropractor and Navy veteran, faces four murder charges in the slayings Monday in the city of Mandan.

The victims' bodies were found at the property management company where they worked. Three of the four had been stabbed and shot, and the fourth had been stabbed.

Morton County Judge James Hill said he agreed with prosecutors' request for the $1 million bond.

Assistant Morton County State's Attorney Gabrielle Goter said Isaak carefully planned the killings and tried to hide them. She said that raised concerns about the safety of witnesses and other employees at the property management company if he's free on bond.

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 say surveillance video shows Isaak entering RJR wearing brightly colored clothing, then leaving in dark clothing after the slayings. They say 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.

The owner of a mobile home park where a man arrested in the slayings four people in North Dakota lived says the suspect "never attracted any attention."
