This is what gets me. Any trained investigator would know NOT to leave the the scene. She should have known they would be looking for her & should have trusted her coworkers to find her. In the years we've seen Sara(as a charactor), we know that she's much more inteligent than what the writes wrote.
I can't count how many times here in the Rockies that someone will get lost & they just keep walking, getting more lost & farther away from the last point where someone had last seen them.
As far as the search went someone in a heli or plane would have been high enough for her to have seen them. She then could have used the mirror.
Your right. She could not have gotten that far from the mustang.
Also, when the killer was lowering the mustang onto Sara. She in no way could have done it without a winch or something similar. They back away & there's nothing but her. NO WAY!
I though CSI writers were better than what we saw tonight.
