A vacationing Tennessee teen was killed and his sister injured by a live electrical wire that was for some reason left in a Guatemala hotel swimming pool.

Seth Washam, 18, was on an academic study program in the country Thursday with his older sister, Emma, when the fatal incident occurred, the Knoxville News Sentinel reported.

Their parents had arrived days earlier in the country to “join them for a week of vacation and touring,” according to a Facebook page of the Knoxville nonprofit A Hand Up for Women.

“While we do not have all the details of the accident, we do know that it occurred due to an electrical wire in a swimming pool,” the page said. “Emma was also injured in the accident and is receiving medical attention in Guatemala.”

Seth was an incoming freshman at Carson-Newman University in Jefferson City, Tennesse, where his 19-year-old sister was a rising junior, according to a statement from the college.

“The prayers of our entire campus community is that God will be a refuge and an ever present help to the Washam family at this time,” said Carson-Newman President Charles A. Fowler in a statement.
