Yet, the caller told the 911 operator about the vehicles in the lot. One was Jessica's car. I'd hope if vehicle 2 left the scene almost simultaneously to the 911 call, LE would have tried to chase the vehicle down. That would be a terrible oversight if it was that close. Also Jessica would have had to be disabled in some way or she would have screamed. Unless he was in the back with her and when the guy was in the store, he took off and passed LE as they were approaching depending on which way - ugh! This is too much.
Maybe this is why we haven't heard much about the second vehicle.
