Hasn't Greta had a lot of these missing college students on her show. Isn't there more than 5 that they have never found. Body style all the same......do you smell a serial killer??
I think this one is more along of the lines of someone wanting to steal some cash from someone using an ATM, only gets $50.00, get's pissed and offs him, runs out of town in a hurry, dumps him along the way and keeps on going.
