This case has always haunted me. I live in South Jersey and was on South Street at the same bar (Abilenes) they were just a week prior to their disappearance. It has always seemed most likely that they were carjacked upon returning to the vehicle or someone was in the vehicle waiting. Also, there are tons of spots along the Delaware that would be vacant at night - loading docks, warehouses, abandoned buildings, etc. Not sure that would be enough to shield disposing of a truck but not sure who would be looking or could even see at that time of night.
