Have not heard about it being related to SafeSport. Have heard rumors that the shooter was Michael (will come back and edit if not the case but I live down the road and that’s what a few local dressage/horse & non-horse people are saying). House was taped off with crime scene tape as well as much of the property as I drove home from work.
Will be interesting to find out what happened, certainly a tragic and unusual situation for our relatively quiet area.
