Two middle school students in Florida have died after their boat capsized during an apparent lightning strike while they were out for rowing practice this month.

A lightning accident on a Florida lake that killed one student has claimed another teen’s life after it was announced that a second child succumbed to his injuries, bringing the death toll from the tragic accident to two.

Three of the five rowers on the boat were treated and released at the scene with no serious injuries, the United States Rowing Association said in a statement.

Another student was missing for 24 hours before divers recovered the student’s body the next evening, fire officials said.

While Langston was taken to hospital to be treated for injuries, the rowing club and a GoFundMe for the pair of teens confirmed over the weekend that the 12-year-old boy had died from his injuries.

"It is with broken hearts that we share the passing of a second rower involved in last Thursday’s weather-related tragedy,” NOR posted on Facebook.

"We are beyond grateful for the outpouring of love and concern from around the world. Please continue to hold our families in your prayers," the club said in a statement.

USRowing said in a statement, “Our deepest sympathies go out to all those impacted by this tragedy.” It said it sent staff members “to lend emotional and operational support to the club and community.”
