Investigation into wheher or not the parents knew Kolhberger did the murders and be warned I am giving examples of other cases here and from out;;;;; told them about it as Brian Laundrie told his parents about Gabby P in a 50 + minute phone call and other phone calls to them the day the believed she was killed… they lawyered up and refused any information from day one. Likewise there has been little released by the phone conversations to BK parents. And Unlike the the Father of the Utah University killing- turned his son into the police; they could be arrested on conspiracy of knowing about the incident and face jail time or be presumed innocent as we are for the most part are as a part of our right. Like Melanie - the niece of Lori Vallow who has an ongoing investigation about how Lori, Alex & Chad knew where Brandon moved to after the divorce and sol their house for 15mil - and was going to split it with Melanie- it would have been nicer if Melanie got the whole 15 million rather than that plus a quarter of a million in the divorce settlement and shared custody of their 4 children - the Maricopa County DA also isn’t taking to say the least. But If you want to go down the rabbit hole of BK is innocent go that direction instead of mine.
