As an aside - and I do mean an aside, I'm not victim-blaming - people are too reluctant to scream and yell. My dad, who was an arsehole but dealt with the scum of the earth professionally, taught us all to do this (following up with more in-depth advice once we reached our teens). Few adults will ignore a child yelling "Help! Call the police!"
Once we're adults we may need to overcome onlookers' doubts by yelling "Get off me, I don't know you!" and appealing directly to them to call the cops. In a pinch, it's better to yell "Fire!" than Help because people are weirdly scared of helping strangers on request.
Anyway, teach your kids to yell like fuck.
It sounds likely this Prussack slimeball made the kid drowsy and took compromising pictures of her. If such images are in the evidence now under consideration, the CPS might allow a retrial for sexual assault of the girl, if not for the kidnapping.
