Donald Vanhorn III, a 53-year-old business owner and U.S. Army veteran, was shot and killed inside his Cleveland heating and cooling shop on February 23, 2018. Vanhorn owned BTU Comfort Solutions on Berea Road. An argument with employee and friend Dennis Perrien Jr., 50, escalated when Vanhorn produced a knife and Perrien drew a firearm; Perrien shot Vanhorn in the chest. Vanhorn was pronounced dead at the scene.

Perrien was arrested without incident, charged with murder and held on $1 million bond. At his first court appearance he agreed to surrender his guns to police. Reports say both men had weapons during the altercation, though what triggered the escalation is not clear. Vanhorn is remembered by his family and community as a dedicated business owner and someone who assisted fellow veterans.

If anyone knew Vanhorn, Perrien, or witnessed what happened at BTU Comfort Solutions that day, please come forward with information.
