As he replaced the headlights on a S-U-V he discovered 16 pounds of marijuana!! The marijuana was hidden inside the bumper. The owners of the vehicle, a couple in their 60`s, say they have no idea how it got there. They bought the S-U-V last fall.. Police traced the vehicle back to Detroit and to a rental car company in Florida. And now, they want to know who put the pot here and who was supposed to get it. Officer Philip Davitt Dickson City P.D. Says "it`s not surprising. It happens all the time. It`s surpirsing that a vehicle would come in for service and someone would leave this much marijuana behind. What the circumstances were I don`t know but you would think they would do everything they could to recover it." The marijuana has an estimated street value of 16- to 30-thousand dollars.
