A mother allegedly left her disabled daughter to die in a feces-covered room inside a disgusting house of horrors.

Liza Lindsay, 41, of Richmond, Indiana, was arrested after her 19-year-old daughter, Caleigh Lindsay, was found inside a feces-covered, padded room inside her home on South 10th Street on July 24.

The teen was found with a partially-attached diaper on and surrounded by 12 dirty ones inside a room that resembled a stall with four feet padding, Fox 59 reported.

The 'stall' door had a hole in. The walls, which appeared to be covered in feces, also had holes in it, where Lindsay claimed her daughter had hit her head during seizures.

Lindsay, who allowed police into her decrepit home, told police Caleigh suffered from microcephalic and mitochondrial diseases, Pitt-Hopkins syndrome, was autistic, epileptic, and was wheelchair-bound.
