Four children are dead after a pair of separate electrocution accidents on lakes in Missouri and Tennessee.
Nathan Lynam, 11, died Thursday night at Children's Hospital in Knoxville, Tenn., Grainger County Sheriff Scott Layel told The Associated Press.
On Wednesday afternoon, Lynam and Noah Winstead, 10, were swimming between two houseboats at Cherokee Lake outside Knoxville when they were electrocuted. Winstead died at the scene; Lynam was resuscitated Wednesday but died Thursday.
Five adults who jumped in the water to help were shocked as well.
Investigators ruled out electrical problems at the dock and have focused their attention on frayed wiring aboard the houseboat the boys were next to when they were shocked, Grainger County Sheriff Scott Layel told the Knoxville News Sentinel.
The houseboat belongs to Nate Lynam's grandfather, Michael Voccola, 58, of Morristown, said Matt Cameron, spokesman for the Tennessee Wildlife Resources Agency. The boys were swimming near a metal ladder on the boat when the electrical current apparently hit them.
In the Missouri accident, also Wednesday, Alexandra Anderson, 13, and her brother Brayden, 8, were killed while swimming near a private dock at Lake of the Ozarks around noon, according to published reports.
Adults standing on a dock heard screaming and jumped in the water. Police say those who jumped in felt electricity and cut off power to the dock. The adults performed CPR on the children but could not revive them, according to a LakeNewsOnline.com report.
The preliminary investigation indicates improper wiring, and the dock had no ground fault circuit interrupter, which allowed electricity to travel into the water, according to the report. Sources could be a boat lift and/or a pump for a water slide. The Missouri State Highway Patrol Water Patrol Division is investigating.
