( Carrollton, Kentucky ) - A northern Kentucky couple is facing charges for locking up his daughter and not feeding her.

Kentucky State Police say 46-year-old Billy Ray Mertz and 34-year-old Robin Mertz would keep Billy Ray's adult disabled daughter boarded up in a basement room and in the bathroom, unfed.

The 23-year-old woman allegedly weighed 86 pounds when police took custody; losing more than 100 pounds from when she first started living in the home in 2009.
