Brian Alexander, 33, is charged with multiple counts of felony child abuse.
The kids ranged in age from 6 to 9 years old.
“He said ‘grandma if I have on a thin shirt it’ll go into my skin.’ He says ‘if I have on shorts it’ll go into my skin,” the grandmother of the kids told WKOW.
Authorities say Alexander told investigators the children were breaking house rules and watching one of those videos.
And he originally denied using these modified darts himself, but court records state Alexander ultimately admitted to firing the darts at the children.
The father of one of the victims says he hopes his son will be removed from his mother’s household.
And the case’s criminal complaint says one victim reported his mother had seen Alexander use the needle darts and did nothing.
The conditions of Alexander’s bail bar him from having unsupervised contact with the children.
