Quite a lot of detail here: http://www.13wmaz.com/story/news/local/2015/01/24/telfair-police-search-for-missing-cobb-county-couple/22276947/
The man arrested “comes from a good home.” Sounds a bit like he reeled the couple in and an accomplice killed them. But why?
Because the couple likely brought a big wad of cash in order to buy a car. I don't know why they couldn't have just robbed the couple without killing them... senseless.
The deceased was looking for a 1966 Mustang, they don't come cheap. The Perp knew the couple had money if they were looking for a 66’. Most likely he convinced them that it was a cash only transaction. Of course the car never existed.
My ex-wife has a nephew who has been messed up by drugs. It is astonishing just how quickly meth can destroy the mind and body of a beautiful young person with so much potential before drugs swamp them.
