However, I got the distinct impression that if that couple hadn't accidentally spotted her, police would never have found her.With cameras, data tracking, and DNA, she had no chance. Just the pings in her rental car would have given a route she drove there and back.

IMO, part of the planning and premediation LE refer to, was disabling the vehicle gps and not bringing her phone.
I think the only clues they had, may have been where she.used her credit card for gas....
