From the article:
"Neighbors at the Everett apartment where Roger Jung lives haven't seen him for about a month. His mail piled up uncollected. His emergency contact was his parents, Jim and Gail Jung of Kirkland.
Because of tenant rights issues, they haven't been allowed inside their son's apartment to look for something that may aid the search, Jim Jung said."
This surprises me. It's a good idea for those of us who are single and renting to notify our landlords to give access to friends and family in the event of an unexplained absence, and/or give house keys to someone we trust.
I think if I were his family, I would risk a breaking and entering charge to look for clues he might have left to his plans when he last left home, in order to save his life, if that is what's at stake.
I hope he is OK and is found soon.
