A very valid question.But my attitude (he may be telling the truth) is supported by 1) he's rich 2) he lived in a rich area 3) violent murders are a dime a dozen there and 4) he has no legs and sleeps without his artificial limbs on...making him even *more* vulnerable,and more afraid,than an ordinary guy would be.
But like I said...he could have been lying through his teeth.
Ask yourself this...at the first shot, wouldn’t the girlfriend scream or otherwise make a sound identifying herself by the sound of her voice? So why did he fire four times? The verdict was changed to murder for a reason, and the reason is obvious.
Your attitude, “he may be telling the truth” isn’t supported by anything. You obviously didn’t see the trial.
