Trial begins for man charged with killing four in Mandan

MANDAN, N.D. – More than two years after four employees of a North Dakota property management firm were killed, the man charged in their deaths is going on trial.

Chad Isaak is a chiropractor and Navy veteran who lived in a trailer home run by the company.  Company officials say they had few interactions with Isaak and have no idea about a possible motive.

Police say they have overwhelming physical evidence tying Isaak to the slayings.

Jury selection that starts Monday is expected to take up to two days, with as much as three weeks needed for the trial.
