Court documents show timeline of accused murderer after crime scene

Details are unfolding about how police managed to track down the man charged with the four murders in Mandan last week.

Forty-four-year-old Chad Isaak, who's accused of killing four RJR Maintenance and Management employees, was living in a mobile home community in Washburn managed by RJR.

Authorities are still trying to find a motive as to why four people in our community were murdered.

What we do know is Mandan Police shared a photo of the truck connected to the crime to other agencies across the state and that's how Isaak was eventually captured.

Police and state agents continue to piece together last week’s murders.

While authorities were at the scene Monday at RJR, we now have information where the man accused of killing the four victims was during the same time frame.

Let’s take a step back.

Police say Monday morning Chad Isaak is accused of entering RJR around 6:47 in the morning and then leaving shortly after 7.

The court affidavit says security footage shows Isaak leaving in a RJR vehicle and parking it at Indigo Signs.

Surveillance video shows Isaak walking from Indigo Signs westbound toward the bowling alley and then toward Bill Barth Ford.

The affidavit says the accused is then seen turning and walking southbound on Red Wing Drive, on the West side of Bill Barth Ford.

Isaak drops out of surveillance video, until he shows up, getting into a white pickup truck at McDonalds and then pulling into Ron Lowman Car Dealership and staying there for a few minutes.

The truck is seen leaving the lot Westbound on Memorial Highway through Main street and then seen again at Flying J truck stop before merging into Highway 25 North.

The truck was then spotted in Center around 8:30 Monday morning.

At this time, law enforcement was on scene at RJR. The first call came a little before 7:30 for a medical call.

As for Isaak's truck, it was seen again through video in Washburn along Highway 200 at 9 a.m.

On Thursday, law enforcement in McLean County recognized the truck after getting photos, Isaak was detained and arrested later that day.

The photo released to law enforcement last week of the truck isn't being released because of the ongoing investigation.

As for Isaak, his next hearing isn't scheduled yet.
