William Augustus Moore (14 March 1961 – 18 April 2001), better known as Willie Haggart, was a Jamaican gangster, believed to have been an underworld kingpin, and the reputed leader of the Black Roses Crew.
Police records show that on November 30, 1993 he was convicted for possession of marijuana and was fined JMD$100 or 30 days and in 1995 he was charged with robbery with aggravation, but the case was later dismissed.
Haggart died acknowledging 18 kids, six of whom were males: "Red Man", Steve, Ryan, "Little Willie", and twins Khorian and Kharian.
On the afternoon of April 18, 2001, Haggart was sitting and talking with two friends from the Black Roses Crew, Ned "Big Bunny" Hinds and Albert "Blacka Douche" Bonner, on Lincoln Avenue, Kingston 13.
