Thank you, everyone, for the welcome back!
The ploy Klunder used to abduct the girls would have worked for the proverbial 98 pound weakling though. Pull up to a place with potential victims and ask them if they want to earn some money doing chores that are within the abilities of the age of victim selected, invite them to get into the vehicle to go ask their parents' permission.
If the targets decline, shrug and drive on. At that point, the perp has nothing to lose since he has done nothing illegal.
Once the victims got into the vehicle without protest, pull out a weapon once the vehicle was rolling again (if the perp thought escape would be a risk). I didn't follow the Kathlynn Shepard case closely enough to know whether this was part of it but it wouldn't take a genius to figure it out.
No Rodents (perps) of Unusual Size required.
