My theory on the bear/belt/earring/pouch is that JB wore the earrings to the event at which she was given the Santa Bear. They were possibly stored in that little pouch, and because they were clip ons and likely hurt her earlobes at some point, were removed. In carrying the bear into the house, one of the earrings dropped into the street, where it was later found. I do not think the earrings, bear, belt or pouch had anything to do with the crime at all, with the exception of Patsy claiming she had never seen the bear.
That was, of course, an OBVIOUS lie and one that is provable because the bear is lying right on the spare twin bed in JB's room, on which is also clothing that Patsy was laying out to sort or pack for the trip, and may also have had the black velvet pants that JB wore that night lying on the bed as well. The crime photo which shows the bear was taken AFTER the crime (obviously) and Patsy would have seen the bear as she was packing/sorting clothes on that same bed.
