I think the window was a diversion , no one came in that way, so I wouldn't expect any hair or fiber there..
Mention of a razor last week..to cut the screen perhaps?..and perhaps they can get fingerprints back on that but why has it taken this long?
I am afraid that she will never be found...very discouraged today.
the other thing...if Lizzie was in that jeep I am so sure they would have found some red fibers from her pj's..her pj's I bet are new to her this year...I bet she didn't have them back when the family still owned the jeep..so any red fibers would not be expected there at all..
of course, that is only relevant if the perp is Ricci or his buddies.....cops may be on the entirely wrong path..
