The parents of 15-year-old Carmen Johnson, who tragically died from electric shock drowning while swimming near her family’s Alabama lake house last April, are speaking out about the rarely reported phenomenon after it took the lives of two more local women this past weekend.
The two women, 34-year-old Shelly Darling and 41-year-old Elizabeth Whipple, went missing after sunbathing on Lake Tuscaloosa Friday afternoon. Their bodies were retrieved from the lake early Saturday morning. Preliminary autopsies for the two victims show the cause of death as electrocution, the Tuscaloosa County Homicide Unit told CBS affiliate WIAT on Wednesday.
“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, 49, told CBS News. “It is something that even people like me now after all these years never had any idea that this even happened.”
Every day, about 10 people in the U.S. die from accidental drowning, according to the Centers for Disease Control and Prevention. But electric shock drownings are difficult to track. It’s known as a “silent killer.”
Even a low level of electric current in the water can be extremely hazardous or fatal to a swimmer -- especially in freshwater, where experts say the voltage will “take a shortcut” through the human body.
“There is no visible warning or way to tell if water surrounding a boat, marina or dock is energized or within seconds will become energized with fatal levels of electricity,” the non-profit Electric Shock Drowning Prevention Association reports.
In fact, Johnson says, he never would have known what happened to his daughter if he hadn’t felt the electric current himself while trying to jump in to save her.
Carmen playfully jumped off the top level of the family’s boat dock into Smith Lake with her friend Reagan Gargis on April 16, 2016. Jimmy Johnson lowered a metal ladder into the water so the girls could climb out. Minutes later, he heard Reagan scream, “Help!”
“My wife thought [Carmen] had done something to her neck, which paralyzed her,” Johnson said. “She started going underwater.”
That’s when Johnson and his son, Zach, jumped in the water after the girls and immediately felt piercing electric shocks.
“Cut the power off,” Johnson yelled to his wife as he started to go in and out of consciousness.
Johnson, Reagan and Zach survived, but Carmen didn’t make it.
“Carmen was grabbing [Reagan’s] leg and was getting the majority of the shock when I came over,” Johnson said.
Johnson later found a light switch at the dock that was half full of water. When he put the metal ladder into the water, the electrical current from the light switch traveled through the dock to the ladder and into the surrounding water, where the girls were swimming.
“As they were swimming toward the dock, within somewhere between the 5-to-10-foot range, is when they started feeling like they couldn’t swim,” Johnson recalled.
Johnson believes that if his family had been educated about electric shock drownings this might never have happened. Now he’s sharing Carmen’s story as a warning to others, along with tips to help prevent similar tragedies from occurring.
His safety tips include:
- Use a plastic ladder, rather than a metal one, so it won’t help transfer electricity into the water.
- If you start to feel a tingle in the water, swim away from the dock, which is where most electrical issues occur.
- Check all of the wiring around your dock, including your ground fault circuit breaker.
- Purchase a Dock Lifeguard, a device that detects electricity on your dock and in the water around your dock. (Johnson works with the company to promote the product.)
“It’s every homeowner’s responsibility to make sure water is safe around their dock before they start swimming,” Johnson said. “People think ‘Oh, this is a freak accident. It’s not going to happen to me.’ And here we are now — 3 dead in a year.”
