Authorities have identified the teenager who drowned in northern Minnesota Tuesday as a foreign exchange student from Egypt.
Ammar Abo El-Nago, 18, drowned while trying to swim to a floating dock in Twin Lakes in Morse Township, near Ely.
El-Nago was visiting Minnesota from Ohio, where he attended Oberlin College, a private institution near Cleveland.
The St. Louis County Sheriff's Office says El-Nago had swam out to the floating dock earlier on Tuesday evening while wearing a life vest.
After returning to shore, witnesses said he was confident he could make it out there without the vest.
As he reached the dock however he went under, and was pulled from the water 30 minutes later. Lifesaving efforts then proved unsuccessful.
According to his Facebook page, the 18-year-old was studying neuroscience at Oberlin.
One of his friends in Ohio, Ritesh Isuri, paid tribute to him on Facebook, saying: "I've watched you grow so much last year, I've watched you thriving your way at Oberlin, I've watched you excelled [sic] at socializing when you so worried about making new friends, there may not be enough words to describe how good you were to others. I'm happy I got to be your friend, your confidant. You will be missed."
