Yesterday (Sept. 6), tragic news broke that actor Michael K. Williams was found dead in his Brooklyn, New York apartment. “The Wire” star was 54 years old.

“It is with deep sorrow that the family announces the passing of Emmy-nominated actor Michael Kenneth Williams,” his longtime publicist Marianna Shafran confirmed to The Hollywood Reporter. “They ask for your privacy while grieving this unsurmountable loss.”

According to The New York Post, drug paraphernalia was found by authorities at Williams’ apartment.

Later on Monday, 50 Cent reacted to the sad news while referencing his Starz series “Raising Kanan.” In a since-deleted Instagram post, the 46-year-old wrote, “Damn if you didn’t see ‘Raising Kanan’ check it out that fentanyl is no joke, killing the clientele. RIP Michael K. Williams.”

In another deleted post, 50 appeared to reference his past differences with Williams, writing, “Don’t ever try to understand me I’m different. I don’t do all the fake love shit.”

While Williams was revered for his role as Omar Little on the 2000s series “The Wire,” he most recently starred on “Lovecraft Country.” The Brooklyn native earned his fifth Emmy nomination for Outstanding Supporting Actor for his role as Montrose Freeman. The “Lovecraft Country” role also won him a Critics’ Choice Television Award for Best Supporting Actor in a Drama Series earlier this year.

Williams was also set to star in Sony’s upcoming biopic about George Forman as the boxing champion’s trainer, Doc Broadus. He recently spoke to Essence about allowing his roles to choose him.

“I made a decision very early on in my career that the two things I will go for when I’m asked to do a role is I will look for the truth and I will tell that truth with as much compassion and as much empathy as I can,” he said.
