Two men died Wednesday night west of Lansing after an apparent murder-suicide, Leavenworth County Undersheriff Ron Cranor said.

Cranor said that about 8:30 p.m., 32-year-old Kenneth McClellan, of Leavenworth, forced his way in the front door of a home in the 25000 block of 164th Street. Once in the living room, McClellan shot one resident in the chest with a handgun. Cranor said 66-year-old John J. O’Brien died at the scene.

Officers believe the suspect, McClellan, was looking for O’Brien’s daughter, who also lived at the home. Cranor said investigators believe the two had a relationship that has been estranged for some time. She had met him about four years ago.

O’Brien’s wife, Benita, 57, fled the house without suffering any physical injuries. The couple’s daughter, 39-year-old Stacy O’Brien, suffered a head injury when she was struck with the gun, Cranor said, but she then fled the house. She was treated and released from an area hospital.

The suspect was found dead at the scene, the undersheriff said.

“He had apparently shot himself outside the residence,” Cranor said.
