Parents of an eastern Missouri infant face child abuse charges for allegedly putting their son in a microwave. Derick Boyce-Slezak and Mikala Boyce-Slezak, the parents were charged Tuesday and are jailed on $500,000 bond. The infant was taken to St. Louis hospital in April when he was under four months old. Doctors found second-degree facial burns and head injuries. A state social worker said at a hearing Monday that the mother blamed the head wounds on the father for dropping the baby while imitating a TV commercial. The social worker said Mikala Boyce-Slezak believes the burn occurred when her husband put the baby in a microwave and briefly turned it on.
