The children of the man who was killed at the Last Stop range at White Hills previously issued a video telling the girl it wasn’t her fault and they bore her no animosity.

The children of the late Charles Vacca have posted a new video urging Americans to sign an online petition prohibiting children from using automatic weapons. Two of the kids and their attorneys appeared on national television, touting their campaign on CNN.
