I found the discussion about it. On thread 27, page 23. Below is the video that was linked:
Question: Do you have any gut feeling about what may have happened? Or do you really, really just not know?
Steve: Got quite a few gut feelings...so...it's not just one.
Suzi: No, not just one.
Jennifer: And then they change from day to day, different stuff you hear.
Those are the direct quotes. If there is another interview that lead to another discussion, then it has been deleted. That wouldn't make sense, because WS doesn't delete things unless they violate TOS -- and discussing a quote from an interview would not violate TOS.
I really think this one of those things where someone on WS misinterpreted something about an interview, and someone else saw it and took it as fact, and then it grew legs and became something it wasn't. It happens on here all the time, and I'm no different than others in that I've done it before.
I'd love for you guys to find something showing the interview, because something like that would make me think differently about the case and help me along. But without a video link, I'm going to respectfully disregard any further discussion about it because it can't be verified in any way so there is no reason to think it exists.
