Michael K. Williams, the 54 year old Emmy Awards winning actor who portrayed notorious stick-up man Omar Little on “The Wire”, was found dead of a suspected heroin overdose in his Brooklyn penthouse Monday afternoon.

A relative of the Emmy-winning actor talked to him Friday, and Williams was supposed to show up to an event Saturday but never made it, sources said. 

The relative then went to Williams’ home Monday, and someone called cops to the address at 440 Kent Ave. just before 2 p.m., saying there was a man there who was “unresponsive’’ and “feels cold,’’ sources said
