IMHO...

1. Child abductions are extraordinarily rarely carried out by strangers.
2. Parents don't generally leave their young children alone in hotel rooms in foreign countries while they go party the night away.
3. The whole Madeliene McCann thing smacks so hard of JonBenet I can barely hear over the din.
4. Ditto for Susan Smith.
5. Cops keep interviewing the parents.
6. Mysterious forensic evidence has surfaced in the hotel room, including droplets of blood on the walls.
7. You know what I said about abductions and strangers? Like, triple it for child murders.
8. And now...now that world opinion seems to be turning just a wee bit...little Madeliene's parents are suddenly calling off their in-person search and heading homeward.

Sorry, McCanns. I'm calling bullshit.
