Right...sounds like fiance went to her place to pick up baby. So she was home at that time, obviously. Were the cinnamon rolls baked by then? Is the whole batch there, or did anyone eat any? Or were there no rolls when he picked up the baby and she made them after he left? If that is the case, she was home for awhile - long enough to at least bake them. Convenience rolls from a tube would take less time than rolls from scratch.
(I want the rolls to play a role, lol!)
Why in the world would she leave her place with her purse and not her car? The only explanation that makes any sense is that someone came to pick her up and she left home willingly, thinking she would return. Or, someone took her and the purse against her will.
