Dayton Police Chief Biehl announces retirement Cornelius Frolik Dayton police Chief Richard Biehl is retiring after 13 years on the job, which means the city will seek new leadership at a critical juncture for police reform efforts and at a time when law enforcement is under extra scrutiny. “It has been the greatest honor in my professional career to serve as Police Chief for the City of Dayton and to work with the Dayton community to improve public safety,” Biehl said. Lt. Col. Matt Carper will serve as acting police chief following Biehl’s retirement. Carper is in his 29th year with the Dayton Police Department.
