At 7:45 the police say they have no evidence to support anything other than the accused acting alone.
At 8:44 the police state that AFTER some phone calls between the mother and the fiance, the fiance bought sandbags and fuel then tried to float a boat. The cops aren't suggesting that the two colluded by talking about buying sandbags and fuel, only that there was a flurry of calls between the two that were electronically registered and went into the timeline in tracking his movements. The context of the phone calls between the two is the timeline, not what they talked about.
The mother when she finally talks to the police, might even say her and the fiance had a fight and she thought Charlise was with him. That those phone calls were her trying to find out what was going on and demanding to speak to her daughter.
Yeah, thanks for clarifying Kurve, I probably should have gone back through the reports again. I'm still not convinced the mother is at least culpable in all this - happy to be wrong, but her life decisions, including recent ones, don't exactly scream "responsible parent" to me. As for the accused, hopefully prison life is one of endless fear for him, although given he's been inside before, he probably knows what to expect. Except this time, as a child-killer rather than a drug trafficker, he might find it's a different experience entirely.
