UPDATE: Man found dead after high-speed chase in Wausaukee

UPDATE: Friday, 4:20 p.m.

The Marinette County Sheriff’s Department has some updated information available about the man who killed himself after shooting at another vehicle and leading police on a high-speed chase Thursday.

They say the driver, Robb DeGroot of Green Bay, was 43 years old. Earlier information stated that he was 35 years of age. He was also driving a GMC Yukon instead of the Chevy Tahoe that earlier reports mentioned.

Preliminary autopsy results have confirmed the cause of his death as a self-inflicted gunshot wound to the head. Toxicology test results are still pending, so it’s not clear if alcohol or other drugs were factors.

Police say they’ve learned that DeGroot was dealing with depression issues and became agitated recently. That’s as much information as they’ve been able to uncover about a possible motive for his actions.

A 35-year-old Green Bay, Wisconsin man is dead from an apparent self-inflicted gunshot wound after allegedly shooting at a vehicle and taking police on a high-speed chase in Marinette County Thursday afternoon.

Marinette County Sheriff Jerry Sauve says the incident happened shortly before 3 p.m. CST when Marinette County Dispatch received calls that a man in a black Chevrolet Tahoe had shot at and hit a vehicle on U.S. 141 south of Wausaukee.

Police spotted the suspect driving recklessly north of Wausaukee and pursued the vehicle west onto U.S. 8. At that point, police say the suspect reached out the window and fired at handgun at deputies.

The chase continued north onto Shrine Road in Goodman, at which point deputies lost the vehicle. Police believed the suspect drove east down a two-track road.

An armored vehicle arrived on scene and drove down the two-track road and located the suspect’s vehicle.  He was found lying face down in front of the vehicle and was unresponsive.  Officers approached the suspect, and found him dead from an apparent self-inflicted gunshot wound to the head.

No officers or citizens were injured during the incident.

The sheriff’s office says the incident is still under investigation.

The Niagara Police Department, Laona Police Department, Dickinson County Sheriff’s Office, Forest and Florence Deputies, Oneida Sheriff’s Department, Brown County Sheriff’s Department, Crandon Police Department, Wisconsin State Patrol, Wisconsin DNR Wardens, Goodman Rescue, Beacon Ambulance, and Marinette County Coroner George Smith assisted in the scene.
