26-year-old Arthur Medici was fatally attacked by a shark in Massachusetts' Newcomb Hollow Beach on Saturday. Medici died after the shark bit both his legs.
BBC News reported that the incident was Massachusetts's first fatal shark attack since 1936.
Although Marisa Medici said she frequently asked her nephew to avoid the Cape Cod waters, he did not heed her requests out of his love for the ocean.
He told his aunt that sharks wouldn't bite him, the Boston Herald reported, according to Newsweek.
> "Always I asked him, ‘Don’t go. Please, don’t go.’ He’d say, ‘Aunt, they’re not going to bite me. The sharks don’t bite me. I’m Superman!’" she said. "When it happened, I couldn’t believe it was him, that it happened to us. There are no words. No words."
Isaac Rocha, whom Medici was teaching to boogie-board, told CBS News:
> "He was screaming and then I saw, like, a shark tail. I swam to him as fast as I could in that moment. I dragged him back to the shore and I got a boogie board strap and I kind of tied it around his thigh to try to stop the bleeding."
The town of Wellfleet issued a statement on Saturday night expressing condolences to Medici's family and friends.
> "We share the grief and pain you feel. We are grateful to the family, friends, beach staff, public and first responders who worked so valiantly to save his life"
A GoFundMe page for Medici's family had raised more than $29,000 by Monday afternoon. Some of the funds will be used to fly the 26-year-old's body to his native Brazil, BBC News reported.
Last month, a shark attacked a man just miles from where Medici's fatal encounter occurred. Gary Sharpless was bitten in the first shark attack to take place in Cape Cod since 2012. The 61-year-old was still recuperating in a Boston hospital, according to NBC News.
