Almeida was arrested July 20 when he showed up for a hearing involving the other five children.
He lived at the house and stayed there at least two nights a week when not traveling for work, the children told investigators.
Maria Gonzalez was arrested July 22 in Denton, Texas, after the girl's 12-year-old brother told police she tended to them at least twice a week while their mother was at work.
She told DHS she had lived at the house but moved out because her daughter was not taking care of the children.
“The victim's condition was so horrific that it would have been impossible for Maria not to have known there was abuse,” a detective reported.
When the DHS worker went to the house and asked the girl where she slept, the girl took the worker to the mother's bedroom and pointed to the closet.
A cup in the closet contained urine and feces.
Aesusena Gonzalez told the DHS worker she thought the girl had been using the cup to urinate in.
