walmart store. this is where a girl named cori bought the ring for a boy named ryan. but it wasn't love always, and the ring was soon gathering dust in the cab of ryan's red pickup truck. but then the strangest thing happened. the truck was reported stolen from here on ryan's farm just a few days before the murders of wayne and sharmon stock in far off nebraska. >> really nothing more than a standard missing vehicle. >> reporter: jim roarer was then a detective back in dodge county, wisconsin. when call came in, experience suggested probably some local joyride, they'd find it nearby. instead, what a surprise. >> our dispatch had received confirmation from a parish down in louisiana that they had the stolen truck. >> reporter: stolen in wisconsin and abandoned way down in louisiana. that's a long way to go. what did you think?
