Damon told the PRESS on the 18th, that the searchers should be searching closer to SD. So I guess Damon did.
(1) you are right about Damon.
(2)The DRC said the info came from two anonymous phone calls.
(3)Bill Garcia, who looked at maps, DW's route, analyzed it all and came up with the idea they should search the Dehesa Rd. Site again (believe this was after the 2 anonymous phone calls, which occurred 1 day apart. I.E. They didn't listen, so had to call them again.)
