My condolences to the family and friends of the young man. Yes, at long last he has been found.
My husband’s freshman year college roommate is/was missing. Happened right around the time we graduated. To my knowledge he’s not been found. He was last known to be embarking on a country wide road trip, hoping to be gone for a few months. I always wonder if they ever found him. Hope so. He was a nice guy.
If you know his name, this woman keeps a very good repository of active missing person cases going back decades, often including details surrounding their disappearances as well as case updates, if any. It's easy to search.
