I am writing a novel about someone who trolls the highways searching for broken down cars. He offers them a tow, then takes them away and murders them. My question is: How might such a person obtain a scanner whereby he can listen in on calls for help, and then show up before the real help arrives? What kind of device would he need? Where could he obtain it?

A scanner picks up signals from the local sheriff's office and maybe a small number of delivery businesses. I have done a lot of traveling and never seen anybody broken down along a highway, although of course there have been a few. Nowadays they call on their cellphones. You should use something like Bates Motel. Or get some ideas here: mentalfloss.com/search?term=murderer
