Michael K. Williams, the actor who portrayed stickup-man-cum-antihero Omar Little in The Wire and racketeer Chalky White in Boardwalk Empire, died Monday inside his Brooklyn home at the age of 54. Williams’ rep, Marianna Shafran, confirmed the actor’s death to Rolling Stone. A rep for the New York Police Department added that Williams was found dead in his home in the Williamsburg section of Brooklyn at approximately 2 p.m. A cause of death was not immediately revealed, pending the results of the city’s medical examiner.

“It is with deep sorrow that the family announces the passing of Emmy-nominated actor Michael Kenneth Williams,” Shafran said in a statement. “They ask for your privacy while grieving this unsurmountable loss.”
