CNN - Brazilian model Mariana Bridi da Costa, whose hands and feet were amputated in a bid to save her from a deadly and little-known illness, died early Saturday. "Unfortunately Mari couldn't resist any longer. She passed away at 3 a.m. today," Henrique Fontes, executive director of Miss World Brazil, said in an email. Renato Lindgren, a friend of the model who runs a blog dedicated to her, confirmed da Costa's death. On his blog, Lindgren wrote that he and other friends were going to the hospital. "On behalf of all the family, we are grateful for the support and the affection that the entire world has sent to us," he wrote. Da Costa, 20, had fought a pernicious disease that has ravaged her body and forced doctors to perform the amputations and extract part of her stomach as well as both kidneys.
