I was watching the 1/11 episode of Law & Order SVU last night and they go to the house of a girl who disappeared as a teen years ago. (It was kind of ironic that it was on the same day Jayme Closs was found). They had found a video of the teen with the prime suspect that was shot when she disappeared. When the father said the girl didn't think she was pretty I immediately guessed the girlfriend of the suspect was the missing girl, since the suspect was a plastic surgeon who could have changed her looks. They threw a curveball with a body in a wall that was thought to be the missing teen, but as soon as the DNA said it wasn't, I knew I had guessed right. Sure enough, the missing teen turns out to be the now adult girlfriend.
I've either seen too many episodes or they're out of fresh ideas.
