HOUSTON-The mother charged in the beating death of her 4-year-old son was allegedly upset that the boy wet himself, according to CPS and court documents the I-Team reviewed. Vastie Coleman, 27, was being held without bond Tuesday in the Harris County Jail for allegedly killing Kyron Barnes. The boyÃ¢Â€Â™s two surviving sisters described routine whippings by their mother in court documents. One of them told investigators Coleman used a cord to whip Kyron, because "the belt was broken because mom kept whipping the kids so hard it broke into pieces." Neighbors in the Villas of Pine Lake Apartments off Sam Houston Parkway were stunned to hear the news.
