The aunt of the victim of the Cape Cod sharks attack prayed to stay out of the water, said that he was mocking his fears

The Massachusetts man's aunt killed on Saturday by a shark in the waters off Cape Cod said he begged his nephew to stay away – but he laughed at his fears.

Marisa Medici said Sunday at the Boston Herald that she was continuing to ask Arthur Medici, 26, not to travel to Cape Cod, but that's where his nephew wanted to go "every day".

"I always asked him," Do not leave. If you like, do not leave. "He said," Aunt, they will not bite me. Sharks do not bite me. I am Superman! "He always made jokes about himself," she told the Herald.

Medici is the state's first mortal shark since 1936. He was bitten as the boogie boarded off Newcomb Hollow Beach in Wellfleet, officials said. However, the specifics of his injuries and the type of shark that attacked him have not been made public.

"I did not know that he would die doing something that he liked. But he did, "said Marisa Medici at the Herald.

Medici cousin Sarah Medici Coutinho, said in Boston 25 years ago, the 26-year-old man had a laugh that "filled a room" – but understood the seriousness risks of his hobby.

"He loved surfing, we knew it was dangerous," Coutinho said. "We knew there were sharks in the area, we would ask him not to go, my mother told him not to go sometimes, but he loved surfing.

Family members have created a GoFundMe page to help cover burial costs and pay for the transport of Medici's body to Brazil. The crowd-funded account exceeded $ 29,000 on Tuesday morning.

Wellfleet officials told Fox News Monday that the reopening of the beach for swimming is under discussion, but "no decision has been made yet." Signs indicating the closure of the beach have been placed at the entrances since the fatal attack.
