(Bismarck, ND) -- A guilty verdict has been reached in the Mandan Murders Trial.
The jury, after deliberating for four hours Thursday afternoon and Friday morning found the defendant, Chad Isaak, guilty of four counts of murder, burglary, concealment within a vehicle, and unauthorized use of a vehicle.
During the three-week trial, the state outlined a case saying that on the morning of April 1st, 2019, Isaak entered RJR Maintenance and Management and brutally stabbed and shot four RJR employees to death.
The defense questioned the integrity of the investigation while the state depended largely on circumstantial evidence that included a fiber analysis of clothing found in Isaak’s possession and fibers found on the victims, and an examination of gun parts found in Isaak’s freezer.
Isaak's maximum sentence is life in prison without parole.
