According to a Michigan Freedom of Information Act request, Lt. Col. Aimee Brimacombe, the controversial second-in-command at the Michigan State Police, has filed for retirement effective May 1. Brimacombe has been at the center of several controversies during her tenure, including recent discipline on her record and a promotion up four ranks despite no-confidence votes from two MSP unions.
Why it matters
Brimacombe's retirement comes after years of controversy surrounding her leadership at the Michigan State Police. Her promotion and continued role in the department despite disciplinary issues and union no-confidence votes have raised questions about accountability and leadership within the state police.
The details
Lt. Col. Aimee Brimacombe, the chief deputy director of the Michigan State Police, filed a pension application on January 29 indicating her effective retirement date will be May 1. This comes after MSP officials previously stated Brimacombe would retire "in the coming months" without providing a specific date. Brimacombe has been at the center of several controversies during her tenure, including a 2021 suspension for using an MSP vehicle for personal purposes and being "insubordinate" when directed to return it. She was also involved in a controversy over an alleged excessive use of force case and a large settlement payment.
