Roy Black, the renowned Miami defense lawyer known for securing high-profile acquittals, passed away at 80, confirmed his law partner on Tuesday.

Black was widely recognized for his defense in the 1991 William Kennedy Smith rape trial, which gained national attention, and for his involvement in numerous high-profile cases over his distinguished career, according to the Associated Press. Representing a variety of clients, including pop star Justin Bieber and IndyCar driver Helio Castroneves, Black was known for his courtroom successes.

Black played a pivotal role in shaping Jeffrey Epstein’s controversial non-prosecution agreement by negotiating terms that effectively shielded his client from federal charges. Working alongside other high-profile attorneys, Black helped secure broad immunity for Epstein and his unnamed associates while keeping the deal concealed from the victims and the presiding judge.
