A 48-year-old man was injured Friday night after a gun went off during what police believe was a family fight.

Jackson County Sheriff’s Department received an open line 911 call at 8:38 p.m. in the 2500 block of South County Road 750E in the Dudleytown area, according to a news release.

First on the scene was reserve officer Shane Collier who was able to detain one person outside the home and secure a weapon, police said.

Collier reported there were two more people inside, but they wouldn’t come out. He also had received information that someone in the home had been shot.

Officers with Seymour, Brownstown and Crothersville police departments also responded. Police were able to clear the house, owned by Roy Clarkson, 79, and found a man and woman in the home.

Police determined that John Newhouse, 48, had a gunshot wound to his right ear. He was treated at the scene by Jackson County Emergency Medical Services, but refused to be transported to the hospital for further evaluation. No one else was injured.

A 38-caliber revolver and ammunition were recovered at the scene, according to police.

Newhouse lives in the home with his wife, Debra S. Newhouse, 53, who is Clarkson’s daughter.

Police said it is not clear as to why one round had been fired resulting in John Newhouse’s injury.

Drugs and alcohol are not believed to be a factor in the incident, police said.

The case is under investigation and will be forward to the Jackson County Prosecutor’s Office for review.

Also assisting at the scene were county Detective Bob Lucas and Officer Jeff Walters and reserve Officers Steve and Charlie Murphy.
