(NEWSER) – One of the masterminds behind this summer's Ice Bucket Challenge died early Saturday in Nantucket. Police say Corey Griffin, 27, dove off the Juice Guys building into the harbor around 2am, floated to the surface briefly, then sank, the Boston Globe reports. An off-duty lifeguard tried to rescue Griffin and eventually recovered his body; officers attempted resuscitation but he was declared dead at the hospital an hour later. Griffin was in Nantucket raising funds for ALS and had called his father Friday night to say "he was in paradise" after raising $100,000 in honor of friend and ALS sufferer Pete Frates. "He was so happy to be able to help him," Griffin's father, Robert, tells the Globe.
