"I thought the "witness" was going to say Laci was at the warehouse on Dec. 23rd??"
I think there is some confusion on this. It will be really interesting to hear why LE & the pros. concluded that Laci never saw the boat, despite what this witness says. MG would have us believe that LE hid this from pros. but it appears that this is not the case.
I think the bottom line is that Geragos is desperate to somehow make the jury think that Laci was in that boat some time before the fateful day of Dec. 24.
I really don't see how he can prove that, though--regardless of whether it happened or not. Because the previews we're getting all refer to Laci's having gone to the witness' warehouse. That might "prove" that Laci was in the area of Scott's warehouse, but that's all.
To me, the only likely time that Laci was in that boat, prior to when her body was dumped, might have been if he took her to the warehouse to kill her!
