After being in a coma for another day, DeRosia died at 12:09 pm on Monday, July 26. The autopsy report ruled the death as accidental and listed the cause of death to be hyperthermia, along with an enlarged heart and obesity. In 2001, DeRosia's mother filed a lawsuit in New York Supreme Court against the promoters of Woodstock 1999 and six doctors who worked at the event; the lawsuit stated that DeRosia died because concert promoters were negligent by not providing enough fresh water and adequate medical care for 400,000 attendees.[54]
