Thanks.
It's still interesting to me if he got on a plane that quickly that he was there on the 20th. I know it's alarming to hear your daughter didn't show up to work, but I don't think my parents would immediately hop on a cross country flight unless they had another reason to be very concerned to hear that news. Getting from the Bay Area to Brooklyn, IA, isn't really an easy trip, either. You probably need to connect, and/or then rent a car/get a ride to Brooklyn.
Given that she talked to her dad so much, and that he came right away, and that he keeps saying stuff about who was in town or coming forward with clues, I'm hoping he has more information than is able to be shared right now. Or, maybe he's just a very concerned father who hopped on a plane immediately after hearing that. Again, we know very little about how their family operated, but she did seem quite close with her father.
