SAN ANTONIO – The two older siblings who witnessed their 3-year-old brother being beaten to death, allegedly at the hands of their mother’s boyfriend, have been taken from their mother’s custody. In a hearing Wednesday, a judge granted custody of the children to their mother’s parents. The suspect, 29-year-old Logan Harvill, was arrested on a charge of injury to a child late last month. Attorneys representing Christian’s siblings say while the mother has not been charged in the case, she was aware of what was happening. A city magistrate set accused child killer’s bond at $1 million.
