Isaak trial: BCI agent says the right suspect was found

Testimony from law enforcement officials continued today (Fri) in a quadruple murder trial in Mandan.

Forty-seven-year-old Chad Isaak is accused of killing the co-owner and three employees of a Mandan property management firm in 2019.

Arnie Rummel, a supervisory special agent with North Dakota’s Bureau of Criminal Investigation, testified that he did not find a motive for the killings.

But Rummel said he is “absolutely” confident that the correct suspect was found.

Rummel said authorities do not always find a motive…adding that “some people just kill for fun.”

BCI agents also said a search of Isaak’s residence discovered a long knife with a bent tip found in a washing machine with wet clothes…  pieces of a firearm were found in a freezer…  and a bleach bottle was found in a shower stall.

Isaak faces life in prison without parole.
