After another two swimmers died in an Alabama lake on the weekend concerns have been raised over the dangers of entering water with electric currents regardless of the size of the body of water.
Lawyers Shelly Darling, 34, and Elizabeth Whipple, 41, are suspected to have died of electrocution after their bodies were found in Lake Tuscaloosa on Saturday.
It follows the death of 15-year-old Carmen Johnson a year ago, who also died from electric shock drowning while swimming near her family’s Alabama lake house.
Her father Jimmy has spoken following the deaths of the latest two women with the danger of electrified water referred to as a "silent killer".
“I’ve been around water all my life and I never thought that electricity in a huge body of water like that could do what it did,” Carmen’s father Jimmy Johnson told CBS News.
“It is something that even people like me now, after all these years, never had any idea that this even happened.”
Ms Darling and Ms Whipple were found dead in Lake Tuscaloosa on Saturday morning after they were reported missing by family members the day before.
"We know there was electricity going through at least part of the pier," Tuscaloosa County Metro Homicide Captain Kip Hart said.
"We're waiting on a full report from the medical examiner to determine exactly what happened."
According to reports the two women were headed to the family lake house to sunbathe that day.
Atlanta Live said family of the two women found their belongings on the dock but failed to located the pair.
A dive team was later called in and the bodies of the pair were located at 4.30am on Saturday.
According to CBS every day around 10 people in the US die from accidental drowning, according to the Centers for Disease Control and Prevention.
However CBS reports electric shock drownings are difficult to record.
