Sweetpea was a dancer/stripper.
During a Strike Team investigation on a series of assaults at strip clubs, Detective Vic Mackey went into the club to investigate. Sweetpea took him to a private room where she danced to him. She then invited him to a nearby alley so they could be more private. As the Strike Team listened through a wire, they heard Mackey and Sweetpea engaging in some sort of sexual activity. After some time, Mackey left and she returned to the club.
