The couple was renting a home and had recently asked to pave over the spot where a body was later found.
Last week authorities went to the house looking for a missing two-year-old girl from Florida, and found her.
They also found an eleven-year-old boy locked in a closet and what’s presumed to be his 36-year-old mother’s body, buried behind the house.
The boy and his 15-year-old sister told police their mother went missing around Memorial Day.
Twenty-five-year-old Michael Sisk and 23-year-old Candace Clark, both formerly of Kentucky, and a third woman, were arrested in the case.
Henderson Kentucky Police Sergeant John Nevels said Clark moved to Henderson in 2005 and Sisk was a long-time Henderson County resident.
