A Georgia family and state lawmakers are demanding a federal investigation into the case of a toddler severely injured by a flash grenade during a drug raid May 28. Bounkham Phonesavanh—19 months old, and nicknamed Bou Bou—remains in a medically induced coma at the Grady Memorial Hospital burn unit in Atlanta. Habersham County District Attorney Brian Rickman told AP his office is investigating to determine whether any officers will face criminal charges. Police said officers were searching for a potentially armed drug suspect at the home and did not know children were inside when they broke down the door and threw in a flash grenade. The grenade landed in the sleeping boy's playpen, according to both authorities and the Phonesavanh family.
