A suspected gunman and a bystander are dead after two officers were wounded and a police dog was killed during a shooting rampage in the central Indiana town of Pendleton, authorities said Friday.

A New Castle man identified as suspect Jim Kenneth Bailey, 58, was found dead possibly by a self-inflicted gunshot, police told NBC station WTHR of Indianapolis.

Police say Bailey, clad in a flak jacket and gas mask, showed up at his estranged wife’s home in Pendleton late Thursday and started firing his gun outside.

Bailey fatally struck John Neal Shull, who was driving past the house in his pickup truck, police said.

When Pendleton police arrived, Bailey grazed an officer, authorities said. An officer from the town of Anderson, who came as a backup, was hit in both legs. His police dog was shot and killed.

Bailey had "a lot of ammunition. He had a will to injure someone," Pendleton police Chief Marc Farrer told WTHR.

Police set up a perimeter and put the town on lockdown as SWAT members hunted for Bailey door-to-door.

They discovered Bailey's body behind his estranged wife’s home at 6 a.m. Friday.

Pendleton is a town of 4,000 about 30 miles northeast of Indianapolis.
