Sports Radio 610 in Houston obtained a draft of the police report which says Peterson admitted that he did, in his words, “whoop” one of his children last May while the boy was visiting him in Houston.
When the 4-year-old boy returned to Minnesota, his mother took him to a doctor. The police report said the boy told the doctor Peterson had hit him with a branch from a tree.
The doctor told investigators that the boy had a number of lacerations on his thighs, along with bruise-like marks on his lower back and buttocks and cuts on his hand.
The police report says the doctor described some of the marks as open wounds and termed it “child abuse.” Another examiner agreed, calling the cuts “extensive.”
