A Powell County man was arrested Sunday morning after Kentucky State Police said he shot his girlfriend, who died. Ralph Allyn, 66, is charged with murder in the death of Barbara Martin, 64.

Martin was found about 6 a.m. with two gunshot wounds "from a large caliber handgun" at her home on Lower Cane Creek Road in Stanton, state police said in a news release.

Allyn was at the home when police arrived. He was arrested without incident and taken to the Montgomery County Detention Center, where he was held without bond.

State police were investigating. Trooper Endre Samu, a spokesman for the state police post in Morehead said the shooting appeared to be unrelated to a fatal stabbing in Powell County about 12 hours earlier.
