SIOUX FALLS, SD (KELO AM) The Sioux Falls man accused of murdering his mother and nephew claims they were essentially mercy killings.
That's the incredible claim of Heath Otto, according to court documents reported by the Argus Leader.
He claims he killed his mom last month because she was sick and not getting better and claims he killed his young nephew because the child was handicapped
Otto is accused of strangling them and cutting their throats with a knife. Police responded to a call at a home on North Cliff Avenue, just north of the city to discover the bodies of 48-year-old Carol Simon and 7-year-old Brayden Robert-Emil Otto..
