(Brookville, IN)--A five-year-old boy drowned in Brookville Lake Tuesday. It happened at Mounds Beach. Investigators say the boy, who was from Cincinnati, walked away from his parents and into the water unnoticed until his body was found. "A ten-year-old girl was swimming in the beach area. She felt something and told her father that she thought she had just touched a body," said Correy Norrod with DNR. Multiple bystanders performed CPR, including Maria Corona. "He started doing compressions. I was holding his chin. Someone else was pinching his nose and putting air into him." But the boy could not be revived. It’s not yet clear if criminal charges will be filed.
