The latest I saw on this story was on our local news station.
A Trucker witnessed her turn out of a service plaza heading the wrong way,and picking up speed.
When he first saw her starting out he started sounding his air horns,and flashing his lights,but she didn't pay any attention to him.
So he started trying to warn drivers on his CB.
he also called 9-1-1 to report what he saw.
The state police took off toward where she was coming, theres a trooper sub station at the exit she was killed.
With everything going on to stop her,it was all to late.
So far the authorities feel she was confussed.
But like you posters we will probably never really know what her problem was?
