The mother told police that her son chose to sleep and stay in the bathroom, and that she tried feeding him protein shakes to increase his weight.
A Utah mom was arrested after allegedly leaving her 12-year-old son locked for as long as two years in a filthy bathroom, where he wasted away to an astonishing 30 pounds and "looked like he was the victim of a concentration camp," according to authorities.
The little boy’s siblings told police that their brother had been kept in the bathroom for between one and two years and they had not spoken with him through the door of their Tocqueville home in six months, the Washington County Sheriff’s Office told reporters.
“A baby monitor was set up so voices could come in but not out. So they could give instructions to the child that was in the room,” WCSO Lt. David Crouse told CBS.
Saying the space would fit his “definition of a torture room,” Crouse said there was fecal matter and urine on the floor, open cans of food and a video camera capable of Wi-Fi monitoring.

Authorities believe the child was also likely kept in the dark, as the light switches in the room were covered and wrapped heavily with duct tape, preventing the light from being turned on.
The severely malnourished boy was found Sunday by his father, according to reports.
He was unable to stand on his own and weighed just 30 pounds, investigators said.
The boy was taken to a nearby hospital, where a doctor treating him reportedly said it was the worst case of malnourishment he had ever seen.
“The child looked like he was the victim of a concentration camp from World War II,” an official told FoxNews.com.

Two other children whose ages were not released were found to be living in the home, but they were healthy, Crouse said.
The mother of the children, Brandy Jaynes, 36, reportedly told police that her son chose to sleep and stay in the bathroom, and that she tried feeding him protein shakes to increase his weight.
She also said she would occasionally lock in him the bathroom for his own safety when she left the home, CBS reported.
Jaynes was arrested and charged with second-degree felony child abuse.
She is being held on $20,000 bail and is expected back in court on January 17.
