A Wisconsin Step-Penis has been accused of turning a Nerf gun toy into a weapon to use against his stepchildren.
Authorities said 33-year-old Brian Alexander shot the children with a Nerf gun modified with sharp needles attached to the end of the darts.
The investigation by the Columbia County Sheriff's Office began earlier this month after a report of child abuse.
The Sheriff's Office worked with Health & Human Services and determined the kids aged between six and nine years old, were being harmed, and not for first time.
'The investigation revealed that this has been occurring for some time,' authorities said, adding they found a Nerf gun with needles at the home.
Columbia County Sheriff's Office Detective Lt. Roger Brandner described the needles as thin sewing-type needles.
Brandner said investigators are working to determine if any other people were present during the incidents or witnessed the activity.
Alexander has been charged with two counts of physical abuse of a child.
