Police: Gunman killed after confrontation at his home in Ohio

DAYTON — A man with a history of mental illness who fled a Dayton home with a gun during a standoff that followed at least one prior shooting has died after being shot by police, a police announced on Tuesday.

Acting Chief Matt Carper of the Dayton Police Department said a 49-year-old man walking his dog on Tuesday said he was shot in the leg after his dog ran toward the house. Police say the suspect fired a gun outside minutes earlier, which neighbors said he had done before.

Police surrounded the house but said the suspect, 21-year-old William Gardner, refused to come out. Police say chemical agents were used, and Gardner eventually emerged from a basement door holding a handgun. He then walked past SWAT officers near the door and walked towards other officers, Carper said.

“Due to Gardner’s weaponization, previous violent actions against the community, and rapid progress toward SWAT officers, lethal force was used to stop the imminent threat,” Carper said.

First aid was administered and Gardner was taken to hospital, where he was pronounced dead on Tuesday morning, police said. Police said a 0.9mm handgun with nearly a dozen rounds was recovered.

Gardner had no criminal history, but had a “fairly significant” and recent history of mental health issues and had been hospitalized, Carper said. Police said last month that relatives had expressed concerns that he might be suicidal or murderous and were also concerned about his possession of firearms, Carper said.

Carper said nine SWAT officers armed with rifles fired a total of 37 rounds. He said the Montgomery County Sheriff’s Department will investigate and police will also conduct an internal investigation.

Police are also investigating a report that another man was shot in the leg Monday at home and Gardner refused to come out when officers arrived. Investigators never found a victim in that shooting, but believe someone was injured, Carper said.
