Sensationalist headline. The bullet fragmented, so - USING BALLISTICS there’s no way to conclusively prove that it was fired from that particular gun. This is because ballistics uses rifling marks on the bullet to identify the gun from whence it was shot. This is not a new or unexpected development. Same thing happens with a shotgun.
The case doesn’t hinge on ballistic evidence, though. There’s still a mountain of other evidence.
The expert will testify that the bullet fragments are a match for the shell casing type (same caliber, manufacturer, etc). The expert will then testify that the strike marks on the casing match the firing pin from the gun. If the gun was registered, then the registration will be submitted as further evidence. Then witnesses will testify that they saw the defendant with the gun, etc, etc, etc.
This seems like either bullshit or REALLY bad judgement on the part of OP.
