Corey Griffin drowned Saturday in a Nantucket diving accident, just hours after fundraising $100,000 for the ALS Association, a Lou Gehrig's disease charity.
Nantucket Police said that Griffin dove into Nantucket Harbor from the roof of a building around 2 a.m. last Saturday. An off-duty lifeguard was nearby and recovered Griffin, who was pronounced dead at a hospital.
Griffin was a close friend of former Boston College baseball player Pete Frates, who together launched the ice-bucket challenge to raise awareness and funds for ALS.
The 21-year-old Frates was diagnosed with the neurodegenerative disease in 2012.
"Griff worked his butt off these last few weeks for ALS. We texted everyday, planning and scheming ways to raise funds and plan events," Frates said in a social media post.
The ice bucket challenge movement has taken off around the country recently. Athletes, celebrities and politicians, as well as everyday folks, have gotten in on the act.
The idea is simple: dump a bucket of ice cold water over your head, then challenge a friend, or friends, to either do the same or donate money to the ALS Association.
