EDMOND — A 19-year-old man “believed he did the right thing” in fatally shooting his parents on Monday at their home, police said.

In an interview with detectives, Michael Elijah "Eli" Walker admitted to killing his parents after an argument that began when he asked them about Satanism, according to a police affidavit. Isaiah Walker, 17, said his brother told him that he shot their parents "because they were sending him messages telepathically and they were Satan worshipers," according to police.

Eli Walker is being held in the Oklahoma County jail without bail.

Police received a 911 call from Isaiah Walker about 2:30 a.m. Monday. Officers arrived at the home at 2601 N Bryant Ave. and found Michael Logan Walker, 50, and Rachael May Walker, 44, dead from gunshot wounds.
