Your theory is plausible but the missing girl in Peru came from a good, established family from what I read. But I also read that she knew who Van der Sloot was and all about his background which makes it amazing to me that she would be in his company with anyone other than a platoon of heavily armed cops. But then again, I’m always amazed at the number of decent-appearing women who want to marry unrepetant criminals with a life prison sentence like the Menendez brothers.
I wonder how many women this freak has knocked off.
