I am freaked out by the description of the man with the baby. JI was the first thing I thought of. But wouldn't the couple recognize him, living so close, having seen him in the media, possibly with a personal acquaintance?
I am sure they've been asked this by the police. I wish we knew if they said, no, it was not him, or yes, I think it was him, or we're not really sure either way. But if there's a chance it could be JI, why wasn't he asked to take a polygraph (if in fact true he wasn't?)
I suppose it's possible that the description has been subconsciously altered to fit a suspect in the couple's minds.
