IIRC when the police got there, they said she was face down, no? I can't find the link now. If that's the case, then they were there when her body was moved, at least once.
IMO, if it's homicide, the brother definitely needs to be looked at closer. The first thing I thought of when I read the stories was, why would he cut her down? Yes, I guess he could have thought she was still alive, but it would also be a convenient excuse for why his fingerprints would be on that cord. Also, it's hard to know from the photos, but if he did cut her down...did he go thru the house and upstairs and cut her down/untie the cord from the balcony? I don't think he did...perhaps he pushed the table over, stood on that, and cut her down. If so, wouldn't there still be a piece of rope left hanging off the balcony? Again, hard to know if there was when police arrived. Would they take something like that down right away? I have a hard time believing they would if they would leave her body lay in the open for hours not to disturb the scene. The other thing I'm sill baffled by is the way her legs are bent. If she died while hanging, I don't see any reason for her legs to be in that bent position. When rigor set in, they would have been straight.
In studying the photos longer, I really think she was hogtied at some point. I know the police said she wasn't when they got there, but that doesn't mean she hadn't been. I googled some hogtied images, and her body definitely looks like it could have been in that position...and many of the images have a gag...perhaps what the blue scarf was used for?
Other questions I have are...where was Neil Nalepa (Rebecca's ex-husband) and is Dina Romano (JS ex-wife #2) remarried? Hence the Romano last name. If so, where was her husband?
