Police today released dash cam footage showing the traffic stop moments before North Charleston police officer Michael Slager fatally shot Walter Scott in the back Saturday.

In the four-and-a-half minute clip, Slager can be seen pulling behind Scott's Mercedes in a parking lot and approaching the vehicle:

Scott, the car's driver, can be heard telling the officer he is planning to buy the car – and so does not have insurance for it.

Slager then returns to his vehicle. The driver's-side door of the Mercedes opens and Scott begins to run. The passenger in the car remains inside.

CNN reports the passenger—reportedly Scott's coworker—was detained and placed in a police car.
