Barring the absence of definitive evidence of a sexual assault and/or robbery... this makes as much sense to me as any theory. Someone wanting potential sexual abuse and/or drug sales not to come out in court proceeding... isn't very far fetched. Keep in mind I DO NOT know what the alleged accusations were or would have been.
Yeah, I follow you. Its worth thinking about for sure.
I'm not sure if I've concocted a scenario in my head at least that gets from "here" to "there", there being the double execution of two 17 year old girls. For most people, that's about the most extreme solution possible...you'd think there would be an a lot more practical, less risky ways to deal with making it go away before you reach that point.
But here's the wild card, which to me would support your scenario...you might be dealing with a real sociopath in this story somewhere, even if they weren't victims of a true serial killer.
See, here's what I keep thinking when considering your scenario, or a similar scenario like the HCR theories. Those theories come down to the girls being executed, one way or another, for "business." Maybe even not true commercial concerns per se, but one way or another they postulate that there was a rational problem for which the murder of the girls was the appropriate solution. It was "just business".
I really have a hard time, though it's not impossible, to put together a scenario in which this was the best solution. There were other ways to get the custody case dropped, other ways to deal with the girls having the tapes, that don't put this kind of scrutiny on the situation. It worked out so far, but normally the last thing you want is the media and 10 different law enforcement agencies (as well as websleuths) keeping a case alive forever. So you really have to build a scenario where it wasn't an option to say, break into the car, or carjack the girls, or pressure another person, or buy someone else, hire a great lawyer or even kill an easier target, etc. It's not impossible, but it's still a big leap for me.
HOWEVER, when you read or know enough about crime that is "business", i.e. the mafia or any kind of organized crime for example...there are incidences of people who are true evil, and whose worse murderous instincts overshadow their business decisions. In the mafia for example...most of the killers are guys like Lucky Luciano, Frank Costello, Carlo Gambino, etc...they're killers...but I wouldn't necessarily call them sociopaths. They live long, successful, incarcerated lives by avoiding exactly the type of extreme response that this double murder would be.
But I have to very much admit, if you look through history, there a handful of others, such as Dutch Schulz, Albert Anastasia, or the Roy DeMeo crew...who were very sociopathic...who chose violence and/or anger for the love of it, and even when it wasn't the right move. Now if you put one of THESE type of characters in the Wiregrass story, and I have no idea who any of those players might be...now I'm seeing it possibly take shape a little more. If you've got a guy protecting some drug turf or whatever, I'm thinking there are better ways to do so...UNLESS it's a truly sick guy who likes to hurt people, or especially likes hurting women. If you're talking about that kind of person, the murder of the girls isn't necessarily the solution to a potential problem, as much as the problem is an excuse to murder.
So whenever I'm tempted to back burner your theory as probably not representing the best, most rational solution to whatever potential risk that was caused by whatever they knew or had...I have to remind myself that there is that more rare, but documented, element of criminal for which this kind of violence is the reason they got into crime, and it was a wonderful opportunity.
I wonder if any of the LE or anyone close to all the players in this drama would be able to look at the cast of characters and pick out one that could be "that guy". The kind of guy that likes hurting people and scaring people more than money or freedom or anything else. When you read and follow a lot of organized crime and corruption, those guys kind of stand out from the greed-heads, small time crooks, or CEO types.
