Name released in Marinette County shooting pursuit incident
MARINETTE, Wis. – Additional details have been released about the Thursday incident in northern Marinette County in which a Green Bay, Wis. man fired a gun at a vehicle and at pursuing police officers, then fatally shot himself.
Marinette County Sheriff Jerry Sauve said that the suspect has been identified at 43-year-old Robb P. DeGroot. It was previously reported that he was 35 years old.
As to a motive for DeGroot’s actions, Sauve said that he had been dealing with depression and had recently become agitated.
Sauve reported that an autopsy conducted Friday confirmed DeGroot’s cause of death to be a single, self-inflicted gunshot wound to the head. Toxicology test results will determine if drugs or alcohol were factors in the incident, he added.
The incident began at about 3 p.m. Thursday on U.S. 141, south of Wausaukee, Wis.
Dispatchers learned that a man in a black GMC Yukon (not a Chevrolet Tahoe, as previously reported) had shot at and hit another vehicle on U.S. 141.
The suspect vehicle was located by Marinette County Sheriff’s Department deputies. The driver, identified as DeGroot, fled in his vehicle at a high rate of speed north on U.S. 141, then turned west onto U.S. 8.
Sauve said that DeGroot reached out of the window and fired a hand gun at the pursuing deputies.
DeGroot then turned north onto Shrine Road in Goodman, Wis., where deputies lost the chase.
When an armored vehicle arrived to assist, deputies searched for and located DeGroot, who was outside of his vehicle, lying face-down and unresponsive.
No one else was injured in the incident.
