I saw an interview with the husband and his dad this morning, and it seemed as if he thought she was dead, and he wasn't very emotional either...
When asked if he would go over there to help look he said "my place is here with my family." then the last comment was "keeping her memory alive"... That's what I found strange. As I said he did not seem distraught at all -- maybe he was in shock or something, but his demeanor still stuck me as strange...
