 On August 5, 2019, Officer Unwin joined the Hamilton Police Department as a Police Officer. Hamilton Police Chief Bucheit said of him, “While Tim’s time here was brief, his impact was significant in terms of the lives he touched and the many relationships he forged,” Hamilton Police Chief Craig Bucheit said in a statement.” He resigned on May 19, 2021. 

On May 24, 2021, Officer Unwin joined the Springfield Township Police Department. By the end of March 2023, he had served his Hamilton County and two communities for more than eight years.

Officer Unwin religiously maintained physical fitness and enjoyed working on automobiles, especially his Subaru WRX STI. He had an infectious smile and Police Chief Richard Bley described him as being liked by everyone that collaborated with him and that he was willing to help anyone that he could.



Early early on March 31, 2023, a Police Officer Needs Assistance was broadcast to all cars and all departments in Hamilton County.  Officer Unwin, traveling north on Hamilton Avenue and, in the 7100 block, struck a vehicle driven by William Kenneth Dunson (50), coming to rest at Marilyn Lane.  His emergency lights and siren were on. Unwin was merging from the right lane to the left lane, after a construction zone, when he lost control of his police cruiser, the release states.

His cruiser then hit a concrete median in the center of the road, causing the vehicle to “trip and roll onto the driver’s side,” officials said, adding the cruiser went into the southbound lanes of Hamilton Avenue and struck a vehicle operated by William Dunson, 50.

Both Officer Unwin and the driver of the other vehicle were killed instantly.
