American Fugitive

Simply pick up a car with the tow truck, find a pedestrian, slowly back into them making sure the car you're towing knocks them down. Boom. Cheevo

There are a few ways to try and get this to pop, but I found the easiest method was the following.

Take a tow truck from Dwayne's or the body shop, or press and buy one from the car dealer. Now drive to any store and back into the ATM until the small black circle with the 'tow' symbol appears by it. Hit and drive off!

You'll be able to swing it around a lot faster than if you were towing something heavier, such as a car. Now head to one of my favourite pedestrian massacre spots (park, motel, graveyard) and either swing the tow truck around in circles or, preferably, reverse at speed into a peep. If they are merely knocked unconscious, repeat the process!

If you're struggling with the ATM method and towing a car is too slow on reversing, tow a car to the crusher found just north of Dwayne's on the first island, and tow the resulting cube after crushing the car.
