That's a very strange case in my opinion. I also think that the abductor (or murderer or whoever it was) acted somewhat weird about the kid who saw him, too. It feels like he was almost protective of this child. I mean, what type of a murderer would tell a witness, even a child, "Go back to sleep, little one, your mommy is sick?" I think that type of man would have threaten this child and tell her something like "Go to bed and keep your mouth shut", this sort of thing. And then he locked the door? Why? Very strange.
