I've only watched Fade to Black once, but my mind keeps going back to two scenes in particular:

1.  The depiction of the morning Jodi disappeared and the extremely unusual way a person of interest acted, repeatedly phoning the friend he usually met each morning, then the unhinged way he acted when that same friend showed up at the convenience store, all this even before Jodi was reported missing.

2.  The scene in which a person of interest gets a phone call in the early morning the day after Jodi disappeared and the abrupt and rude way in which he forced a woman friend out of his apartment immediately after the phone call. This latter event REALLY made me reconsider my position that Jodi was abducted by one person.  Now I wonder if there was an accomplice, who had upsetting news that morning. It made me wonder if maybe Jodi was even still alive the day after her abduction...
