My cousin Robert A. Harrison was last seen in Jupiter Fl. He has now been missing for appx. 5 weeks. He is 39 years old, blond hair, blue eyes. His truck and keys were recovered in a trailer park in Palm Beach Gardens. The information we received so far says that because he is an adult they really cant do much. There is a man that had his truck and keys and they will not treat him as a suspect. What do we do? PLease help us
