 What started as a call for a missing three-year-old has taken a tragic turn after the boy was discovered in a swimming pool. Rockville City Police responded to Elmcraft Court late Friday night where the child was found in a neighborhood pool. Officers performed CPR. The boy was taken to a hospital, but he was pronounced dead there. No foul play is suspected, but Montgomery County Police detectives are investigating the child's death. Police do not anticipate to release the boy's name.
