In a shocking new episode, gripping series Autopsy investigates the mysterious death of beloved ’90s comedian, Bernie Mac.

In the show, celebrated medical examiner Dr. Michael Hunter analyzes the late star’s cryptic autopsy — all in an attempt to uncover the truth behind the stand-up-comedian’s untimely passing.

Known as one of America’s most iconic performers, Mac began his career as a poor funny-man strolling the streets of Chicago. After performing in various local clubs, he was chosen to star in Def Comedy Jam — a role which led to his mainstream success and fast-growing Hollywood fame.

While the star never gave in to drugs or alcohol, his addiction to cigarettes — which began as a mere hobby — grew, along with his fame. Eventually, his constant tobacco intake led to serious respiratory problems for the comic.

One night in 1996, Mac woke up with an uncontrollable coughing fit, which medical professionals agree could have been caused by inflammation in his respiratory tract. The star later admitted that this horrifying episode is what persuaded him to quit smoking for good.

Years later, the comedian still showed signs of deep respiratory problems. Former co-star Reginald Ballard even admitted in the show’s latest teaser: “He couldn’t really finish sentences without taking another breath.”
