With all the information KK disclosed with very elaborate details, she never disclosed a motive that I read or heard. She said he told her that KB was abusing drugs/alcohol and abusing the baby which was never corroborated. What is his motive? LE says could be custody because of the paperwork from August that wasn't filed found in his house but it seemed like KB let him pick up the baby and take her out at least. According to him, they shared the time based on their work schedules and perhaps holiday schedules to share time with the baby with their families, etc.
But she was still in charge because she was the mom and likely did primary care because there was no formal parenting time agreement? He had a family law attorney and he appeared to have that relationship at least in the beginning of this missing person now murder case. She seems to know every detail, what about motive?
No calls to social services regarding KB's parenting or lack of, no reports from her workplace regarding issues with substance abuse. No friends commenting on her parenting. It's like he was living a double life. One with her taking care of the baby and doing a great job at it while he bad mouthed her to his family, mistress, and anyone who would listen about how she was a rotten mother.
