Like lemmings to a cliff... Who in a sane mind takes their 9 year old kid into a dangerous canyon down goat trails on the edge of a cliff? Forget the possability of poaching that guy shouldn't have custody, that's child endangerment. I know the canyon well and there is only four spots with a straight drop that high and three of them are off the trail atleast 15 yards. These three spots are all very close to the campground/blood rock area which is where I am assuming this occurred as the fourth one is a very dangerous little switch back that no child should be near. There are more spots where a fall like this could occur but they would be more of a very long tumble than a "100 foot fall" like the radio and news has reported.
Some people may hate my comment but it is what it is and that's natural selection at its finest sad to say.
