"Unreliable eyewitness accounts" = four different people who don't know each other stating that they saw her in different places at different times after the boat docked. And at least one of those witnesses saw the tasmanian devil tattoo she had. I'm not sure I agree with you a hundred percent on your police work, there, Lou.
Look, I don't know what happened to her, and it's impossible to state definitively what happened to her just from watching that Netflix documentary. My only point is that your "zero evidence" comment simply isn't correct. There is, in fact, substantial evidence that she didn't fall overboard (either assisted or not). The problem is that evidence isn't conclusive. But, then again, neither is the evidence relating to the "she went overboard" theory. (No body ever washed up, all kinds of evidence that she wasn't suicidal, etc.)
