Tragedy almost struck Saturday when a boy went underwater while swimming between an island on Lake Lanier and the shoreline in West Hall County. With Department of Natural Resources on the way, witnesses had rescued the 12-year-old boy by boat, brought him to the island and were performing CPR on him, Cpl. Adam Loudermilk said. Emergency responders also arrived at the scene off Ahaluna Drive and worked to put the child on Loudermilk’s boat.
