Pretty pathetic that most posters here are wanting to blame the girlfriend and not Johnny. She hasn't given anyone a reason to doubt her and Johnny hasn't given anyone a reason to believe him.
Posters have flat out lied and said the police didn't believe her. The police said she was being too vague and uncooperative. Another words not enough info or evidence to make an arrest.
Oh for the record it takes no longer than a half hour to drive from Fort Worth to Dallas in moderate traffic, less if traffic is light. Made the drive 5 days a week for 3 years
