As the search for Andrew Koening, the former Growing Pains star and son of Star Trek's Walter Koening, intensifies a cryptic letter has been discovered.
RadarOnline.com has the note  which was pasted to the door of a neighbor before Koening disappeared from his apartment and was last heard from in Vancouver before seemingly dropping off the face of the earth.
"He started putting all his stuff out front trying to sell it. I actually got a cabinet from him because he said he was going to put it up on Craigslist for $175 but that if I wanted it I could just have it," the neighbor said.
"He told me he was going up to Vancouver and was excited to go on vacation. Looking back though, it's weird that he got rid of everything he owned before going on a vacation.
"He was a nice guy, always very friendly with me. I hope he's alright."
