Lt. Col. Aimee Brimacombe, the Michigan State Police's chief deputy director, has quietly set May 1, as her retirement date, according to pension paperwork obtained through a Freedom of Information Act request. Her planned departure comes on the heels of years of internal investigations, courtroom battles, and a near-unanimous vote of no confidence from rank-and-file troopers.
FOIA Records Lock In May 1 Exit
As reported by the Detroit Free Press, the Michigan FOIA response includes Brimacombe's pension application filed Jan. 29, which lists May 1 as her effective retirement date. When a Free Press reporter emailed Brimacombe yesterday, an automated reply came back saying she would be out of the office until the beginning of April.
Fast-Track Promotion Under Grady
Brimacombe's rise to the number-two post at MSP was swift. In December 2023, she was promoted four ranks to lieutenant colonel and named chief deputy director by Col. James Grady, according to a Michigan State Police news release. Grady himself had been tapped as director a few months earlier, after Gov. Gretchen Whitmer appointed him in September 2023, as noted by the Governor's Office.
Discipline, No-Confidence Vote, And Oversight Heat
A January report from the Michigan House Oversight Committee lays out a series of Professional Standards Section investigations into Brimacombe's conduct. The report notes that in 2021, she received discipline that included a five-day suspension for personal use of a Michigan State Police vehicle and findings of insubordination. Lawmakers link those issues to mid-2025 union votes that showed little confidence in agency leadership and to subsequent calls for greater accountability at the department, per the House Oversight Committee report.
Legal Fallout And A Near-Million-Dollar Deal
Federal court records add another layer to the picture. In filings and a related opinion, Brimacombe, acting as the MSP's risk-management lead, is described as approving a $999,999 settlement in a lawsuit involving troopers. Plaintiffs point out that the figure landed exactly one dollar below the amount that would have triggered review by the governor. The details about that settlement and its timing are laid out in the court documents, as per the Federal court documents.
Uncertain Future For MSP Leadership
If Brimacombe follows through on a May 1 retirement, the agency will be left with a vacancy in its second-highest job at a time when pressure is already building on Director James Grady. Republican lawmakers have publicly urged Grady to step aside, while the governor's office has stood by his appointment, leaving the department's leadership picture anything but settled. Michigan Public has reported on the oversight findings, and state Senate Republicans have issued statements pressing for further action, per the Michigan Senate Republicans.
