Things are getting more interesting in the case of Andrew Koenig, missing since Valentine's Day when he was last seen in Vancouver. His parents, Judy and Walter Koenig (he played Chekhov in the original 'Star Trek') are in Vancouver helping police search for their son.

Apparently, they were all set to appear on 'Larry King Live' (weeknights, 9PM ET on CNN), but abruptly left the studio without explanation.

You have to wonder if they received information at the last minute that they couldn't talk about. Or maybe they're just too distraught to talk about it. Either way, it's all very sad, and we hope Andrew turns up safe and sound.
