Or perhaps he was part and parcel of the depravity.
His Wiki biography is interesting. Married 3 times -one adopted daughter (that would be the one who had him declared dead July 2011).
His brother committed suicide in 1996 - very similar surroundings.
Could be that the Gricar brothers were abused as children and Ray couldn’t handle what he found, who was involved and the extent of the depravity.
That would traumatize most normal parents and grandparents.
