He was 100 years old. I don't know why, but there isn't a lot of news about this. If you are wondering who Bill was, this may help http://en.wikipedia.org/wiki/Bill_Haast
Sad stuff for reptile people he was a huge part of antivenin research and venomous snakes in general.
Wow, 100 years old with that many deadly snake bites... I wonder what made him up and move to Utah and close the Serpentarium... He really was a visionary.
