"The Wire" actor Michael K. Williams died of an accidental overdose, medical examiner says

Michael K. Williams died of an accidental overdose, the New York City Chief Medical Examiner's office announced Friday. The Emmy-nominated actor, best known for his role in "The Wire," was found dead at his Brooklyn home earlier this month.

The 54-year-old's cause of death was "acute intoxication by the combined effects of fentanyl, p-fluorofentanyl, heroin and cocaine," the medical examiner's office said. The office said the manner of death was an accident. 

New York Police Department sources previously told CBS News that officers responded to Williams' home at approximately 2 p.m. local time on September 6 and found him dead in his living room.
