There was more to the case then Ayoobs articles pointed out. She was shot in the head several inches behind the ear and on the left side of the head, although she was right handed. The defendant claimed she wanted to make it look like he killed her. He claimed she had tried to commit suicide twice in the past by shooting herself. Why would he, knowing this, make ammunition she wouldn't be afraid to shoot, teach her how to use a firearm and leave the gun and ammunition in a place where she could get to them unsupervised? If she had shot herself, even with a low powered load there would have been some trace evidence of powder residue on her hand. There was also the question of the lack of tattooing or GSR on her head. If she had held a gun in her hand and put it up to her head there would have been evidence to support this, especially if she held it in the position she would have had to be in to shoot herself in the location of the enty point. This was the evidence that sent him to jail, and the fact that the rounds were light loads would have made no difference, the evidence should have been there maybe not as much but there should have been something.
The use of handloads did not send him to jail, it was all the other evidence that he could not answer or account for. What power level were the reloads at? .38 S&W, .38 short colt, .32 short, .25acp? These all leave evidence, if not they would be used by a lot of hitmen and all they would have to is claim the person committed suicide.
Everyone has their reasons for not wanting to carry reloads, but if not wanting to have the prosocuter accuse you of something is it, maybe CCW isn't a good idea for you. If he thinks you are guilty of something he will use everything he can think of to get a conviction. This is why there are expert witnesses, to argue the facts of his accusations. But if you are guilty the best experts in the world won't get you off, most of them won't even try, they are there to tell the truth about the facts the best they can. If they lie and get caught at it their expert days are over.
