The pattern on the gear shift knob is for a four speed. I bet the gear shift has fallen downward because the tranny is missing. Raised up it would have the classic forward curve toward the dash. Is that a reverse lockout tab just below the gear knob? Top loader me thinks,,,,,,,,
Other clues (mustard stain on the floor, scuff marks on the seat, angle of the car in the garage, etc.) would lead one to conclude the driver was male, brown hair, of medium build and was wearing jeans and a tee shirt at the time of impact..............and he was going to fast for conditions.
Don't you just love a good mystery!
