Police began their investigation on Wayne Sperling, 66, and Lorinda Bailey, 35, when Baiely took her two year old son to St. Joseph's Children's Hospital towards the end of September to be treated for a cut on his forehead.
The emergency room doctor said the child was non-verbal, unwashed, and smelled like cigarette smoke.
Denver Police, along with a Denver Human Services caseworker, went to the apartment of Sperling and Bailey to check on the three children ages 2, 4, 5, and 6.
Sperling who said he was the primary caregiver was 'applying to home school' the oldest, six year old boy. He also said that the children could communicate with him and Bailey despite their lack of verbal skills. He said they had their own language where they 'grunt at each other.'
Authorities found their children malnourished, surrounded by feces, and only able to communicate via grunting sounds. Police said they were so malnourished that they couldn't developmentally distinguish between any of the boys. All of the boys were also described as developmentally-delayed and none of them were toilet trained.
Sperling and Bailey are currently in custody and each being held on a $5,000 bond. Court is scheduled for Tuesday, October 8.
