I thought about "The Candy Van".
Seriously though a few years ago there was an amber alert for some guy in a white Dodge conversion van that had picked his grand daughter from school and never came back home.
It got full local media attention. In the meantime everybody at work started referring to my white Chevy conversion van as the molester van. In fact I actually parked it until the search was over.
One day I stopped to talk to one of my neighbors when a police car showed up. The officer told me that a white conversion van had been spotted in the neighborhood and someone called the police! He says, "I realize this is no the van we are looking for but we had to investigate it". Despite the situation, I found it kind of amusing. Not that I find doing harm to children amusing.
The eventually found the guy. He and her had been living in a campground or park somewhere in the general area.
