S3·E4 The Cheerleader Murder

Hooker and Romano, with Stacy and Corrigan, catch the thief of a freshly stolen car, but in the car's trunk, they find the body of a teenage girl. With the coroner's report revealing that the girl was a heavy cocaine user and had had a recent, crudely-operated abortion, they find themselves uncovering a racket that is getting young girls hooked on drugs and then leading them into making underage porn movies to pay for their addiction.
