Well I'm 6'1. 205lbs... Still a slim guy... And every guy, will size up another male and know roughly what a fight with that person would be.. I don't think a gun would have been used... Tim's size appears to be same frame size as a person like DM... Not as tall, but his overall size was on slim side. Police seem content the 1st truck owners size was a deterant...which means the size difference from first truck owner to Tim was much greater..
I suspect the Stun gun was used inside the car, I suspect DM was the driver , TB was passenger and the second suspect was sitting behind,
