The Seattle Times has a fair account of the attack by the goat, best I've seen so far -
http://seattletimes.nwsource.com/html/localnews/2013189753_olympicpark18m.html. It sounds like even a tourniquet would not have made much of a difference. The goat was standing over him and couldn't be waved off for at least 15 minutes - another part of the account says first medical assistance couldn't begin for almost 50 minutes, by which time the victim had lost alot of blood and had no pulse.
