Well, it keeps getting stranger. One of my coworkers called his parents directly and they talked to one of his friends. Adam talked to his friend on the phone and said he was in Missouri and they think he is on his way to Phoenix. It sounds like he had some trouble in Missouri though. The friend also said that Adam said he was fine physically. But, he was rambling and wasn't very coherant.
So, once we thought he was probably in rehab, but now he is travelling across the country without his cell phone, car, or Ipod. Nobody has any idea how the hell he is even travelling (Greyhound, friends cars, etc). The friends also sound kind of shady and that makes it even tougher to believe anything from them.
