Emergency crews were on the scene of a person shot and a subsequent standoff in South Toledo on Wednesday afternoon.
Police negotiated with a man with a rifle in a back yard off Emerald Avenue.
The suspect, identified as 49-year-old Christopher Krauzer, never pointed it at officers, police said.
"They were arguing. The boss was out there taking pictures of what he broke and, uh, then I just walked in the back door for a second. I heard a shot came back outside and the boss is laying there face down bleeding," said witness, Raymond White.
A perimeter was established in that area and SWAT and negotiators were called to the scene.
Police say Krauzer was threatening "suicide by police."
Officers negotiated with Krauzer at Logan just off Broadway and were able to get to the victim, who was identified as 75-year-old Gordon Capshaw.
Capshaw was taken to the hospital where he later died.
Krauzer was taken into custody shortly after the negotiations began.
He was initially charged with felonious assault, and is now being charged with murder in light of Capshaw's death. His felonious assault charge was dropped.
Krauzer is being held in the Lucas County Jail on a $1 million bond.
He is scheduled to appear in court for a preliminary hearing on October 13.
