First of all, how does a nurse who is on duty happen to have her car keys on her when they go out to her car? No purse, no jacket, but car keys she carries with her.
How does she have a change of clothes and money for a hotel room if she left with nothing (except those mysterious car keys).
When he was doing research at the library, the date said body found on
"June 31th". No one caught that???
It was just not a good movie
