Kintell "Prince K" Williamson is a Jamaican drug kingpin from Baltimore's Park Heights, on the Northwest Side. Kintell is recognizable by his long dreadlocks and beard.
In the third season, the Major Case Unit briefly targets Williamson because they can easily connect him to murders, and Police Commissioner Burrell and Lieutenant Daniels want the stats for political reasons. McNulty intervenes and gets the Unit to re-focus on Stringer Bell and Avon Barksdale. Williamson stops killing people after joining the New Day Co-Op. When Avon continues warring with Marlo, the police arrest several of Williamson's dealers as a general crackdown on drugs, leading him to push Joe to confront Stringer and Avon.
