Challenge co-founder drowns

Mr Corey Griffin.

The co-founder of the Ice Bucket Challenge, Mr Corey Griffin, died after drowning in a diving accident on Aug 16.

The 27-year-old died at Nantucket Cottage Hospital in Massachusetts, after jumping from the roof of a two-storey building into Nantucket Harbor, according to police spokesman Carlos Moreira.

No other details were provided, the Washington Post reported.

Mr Griffin, a former Bain Capital manager, has raised a huge amount of money for the ALS Association through the challenge.

Mr Griffin's friend and family spokesman Michael Greeley said he suffered two crushed vertebrae in the accident.

"This is a kid who went from having a big smile on his face to being dead instantly," Mr Greeley said in a telephone interview on Monday.

Diving off the building on Straight Wharf is "a rite of passage" on the island, said Ms Tiffany Lee, a bartender a local restaurant.
