It seems a bit sexist to believe that a mother would not cause her daughter the pain of leaving vs a father would cause a daughter pain by murdering her mother. Men and women are not some breed apart, they can both do horrible things to their loved ones. The website is crawling with the stories of mothers who have done the wrong thing. And leaving because of some personal crisis is far less terrible than murder.
The police have evidence we don't know about, but I do believe even if there is no evidence of foul play, no forensic evidence of violence in the home, Borce's and AR's comings and goings, phone calls, internet searches check out, and they have soft evidence she has left such as money missing, or she has confided in someone she wants out, the police would be pursuing this when she has apparently dropped off the face of the earth. Because of people like Lorrin Whitehead and Liesl Smith they need to go out hard and fast else the questions will ever be asked if they could have done more.
Anyway, I continue to have my fingers crossed she surfaces in some out of the way place, or makes contact with someone.
