Court documents reveal child was secluded, deprived of food
"According to court documents, Tyler repeatedly assaulted the child with the handle of a flyswatter and encouraged their dog to attack and bite the child. The child now has permanent scarring on his back and limbs, along with post-traumatic stress disorder symptoms.
At the start of the 2017 school year, teachers observed his repeated food-seeking, low body weight and hair falling out in patches.
Teachers and school administrators reported the child was a quiet boy, a loner, well-behaved and always hungry, causing personnel to have great concern for his welfare.
The child eventually told his teacher he was being confined under the stairs after school each day and deprived of food. The school made a report to the Iowa Department of Human Services, which led to an unannounced home visit.'
