IF it had been a honest and true explanation for Karen, leaving the home, I would fully understand the situation: I'm the director of Bella Bleu and just got told by my husband (or just have read in a "mysterious" letter), that I have from the day after tomorrow to deposit the daily revenue onto another account, to which I have no access. Very nice surprise. I would feel ousted by husband AND daughter, as also controlled by them. No wonder, there was yelling and screaming! And going ballistic would have been a normal reaction to such a sneaky attack (by "loved ones", one of them I had a "special bond" to).
I would have left the home, the husband and the daughter and the dog - if I had been able to ....
Allegedly, KR planned to leave BR after SR's 21st birthday party. We know that people generally don't leave relationships/families where they feel loved, valued and belong. Now, it is uncovered that BR had allegedly undermined KR with the establishment of Envirovision. Hypothetically, the implications for KR on uncovering these 'covert' dynamics could have been overwhelming: the hurt and shock of being 'betrayed' by her own family; her business undermined; her inheritance arbitrarily out of her control. She had been violated. It's not difficult to imagine that a highly emotive 'conflict' erupted.
Hypothetically, it's not difficult to imagine that BR may have reacted with rage at KR's reaction and plans once Envirovision was discovered and his 'covert' attack on her finances exposed. Hypothetically, what else did KR know about BR's business dealings which she may have threatened to expose?
In this case, the core family dynamics are a 'triangle'. In a relational triangle, there is always the potential for two to side against the third. If KR believed that SR was involved in the 'covert' attack against her orchestrated by BR, this could have been deeply hurtful.
Not only was KR murdered and her body abandoned in the bush, hypothetically, she may have suffered much hurt and anger at the violations discovered before she was murdered.
This was not a loving, nurturing family IMO. Hypothetically, it appears that relationships were fractured with 'covert' dynamics, interests and conflicts.
My opinion only based on information gained from MSM.
