I guess I thought if they were just searching new areas, not based on any new info, they would go ahead and take volunteers to use as many people as possible. The small number of LE-only searchers made me think (hope) they had specific reasons for being where they are.
Ya I can see that being a possibility. They mentioned "general searches" and "specific searches" in news broadcast. I dont know if they were referring to tips they've had, or maybe highly probable areas.
I really dont know what to think at this point. I dont know what new evidence they would have to lead them in these directions.
Since the beginning I also had two thoughts of the direction the perp might travel.
1)If he didn't plan on keeping Sierra long, he might head west towards the various reservoirs, or head south.
2)If he planned on keeping her longer, he'd probably head south.
At that time of day, heading north toward SJ/SF would not be probable due to traffic.
But he problem is, knowing the direction doesn't mean much. Heading south, he could go to LA, San Diego, Arizona, Mexico, etc.
Thats a lot of area to search without any specific leads IMO.
