Alton Henry Maddox, Jr. (born 1945) was an African-American lawyer who was involved in several publicized cases in the 1980s before his law license was indefinitely suspended in 1990 by the New York State Supreme Court.
Maddox represented several proven and alleged crime victims including the family of Michael Stewart, a Brooklyn man who died while in custody of the New York City Transit Police. Six officers were indicted for the death; all were found not guilty. Rudy Giuliani, then US Attorney in Manhattan, found insufficient evidence to warrant a federal grand jury investigation. A Metropolitan Transportation Authority report later faulted police for use of excessive force.
