The Wire actor Michael K Williams died of an accidental drug overdose, a post-mortem exam found.
Williams, 54, was found dead in his Brooklyn apartment on September 6.
Law enforcement sources said at the time that drug paraphernalia was discovered at the scene.
Julie Bolcer, a spokeswoman for the New York City Office of the Chief Medical Examiner, said in an email that the cause of death was “acute poisoning from the combined effects of fentanyl, p-fluorofentanyl, heroin and cocaine.”
Bolcer declined to comment further on the investigation.
Williams’ colleagues recalled his special talent for humanizing the characters he played, bringing his own experience as a black man growing up in New York to his roles.
Among the real-life struggles he was based on were episodes of drug addiction, which led to his best-known role for The Wire.
The television series was set in Baltimore and told the story of narcotics trafficking from the perspective of criminals, the police, and the people caught between them.
Critics praised Williams for his portrayal of Omar Little, a homosexual drug dealer at war with his rivals.
Other television roles that won praise from Williams included characters he played on Boardwalk Empire, Bessie, and Lovecraft Country.
Williams played the powerful African-American gangster Chalky White in Boardwalk Empire, an HBO series set in Atlantic City, New Jersey, during the Prohibition era of the 1920s.
During her career, Williams earned Emmy nominations for performances on HBO’s Bessie, The Night Of, and Lovecraft Country.
He also earned praise for his role in the 2019 Netflix series When They See Us, the true story of five teenagers falsely accused of a brutal attack on a runner in New York’s Central Park, who were eventually exonerated after passing years in prison.
