The two women, 61-year-old Linda Nickle and 24-year-old Elizabeth Newcomer, were found about 5 p.m. Saturday in the 6800 block of Westdrum Road.
Sgt. Paul Thompson, a spokesman for the Indianapolis Metropolitan Police, said Elwin Hart, Indianapolis, called police from a nearby church to turn himself in about 20 minutes after the bodies were discovered.
Thompson said a domestic dispute might have been the cause of the shootings.
The couple lived together in the home. The couple, he said, bought the house to rehab it and that there may have been an argument Friday possibly related to the house that spilled over to Saturday afternoon.
Police said Nickle’s son, who was out of the city at the time, knew about the argument and became worried when he was unable to reach his mother and Newcomer, so he had a friend break into the house in an attempt to make contact. The bodies were discovered at that point.
Newcomer also resided at the house.
Hart was arrested at the Lynhurst Baptist Church, 1250 South Lynhurst Drive, about 5:30 p.m. Saturday.
Thompson said Hart also faces charges for possession of marijuana after police found several bags of the controlled substance and a one-hitter pipe in his possession.
