A Toronto Life article by Simon Lewsen that includes a profile of lawyers investigating tow truck fraud:
Tow truck drivers are eager to be first on the scene—some are even willing to risk death or injury—because a single vehicle can yield a massive payout. If you’re an unscrupulous driver, the tow fee is only the beginning. Somebody has to fix the battered vehicle, after all. Maybe you refer that job to one of your buddies with an auto-body shop. Maybe, in return, he gives you a cut of the profits. In some cases, you and your friend might even exaggerate the extent of the damage or deliberately wreck the vehicle further.
As for the passengers of the damaged car, they’re going to need a taxi ride home, a rental car for the next few days, maybe even some physiotherapy. You can award these contracts to your cronies in exchange for a piece of the action. Before and after repairs, the car itself has to go somewhere. Perhaps you send it to a lot far outside of town, a trip with a hefty price tag. For every day it sits there, the car racks up storage fees.
