Wednesday’s services took place at St. Stephen’s Episcopal Cathedral and were streamed on Facebook. Several stars were in attendance, including Queen Latifah, the co-creator of The Wire David Simon and Williams’ The Wire costars, Felicia Pearson (Snoop), Andre Royo (Bubbles) and Jamie Hector (Marlo).
Williams portrayed Omar Little in the hit HBO series. The role has been lauded over the years for its complex depiction of a gay Black man with a reputation as a ruthless criminal in the streets of Baltimore.
Although his cause of death has not yet been determined, drug paraphernalia was found in the apartment, the New York Post reported. A separate law enforcement source told PEOPLE that Williams died of a suspected overdose and that officials believe he may have used heroin laced with fentanyl.
