Rhonda McCullough, the widow of Bernie Mac, has filed a wrongful death suit against Dr. Rene M. Earles, a Chicago dermatologist who’d treated Mac. The comedian died on Aug. 9, 2008 of heart failure after pneumonia. He’d also long been suffering from sarcoidosis, an autoimmune disease. The suit alleges that the doctor failed to recognize how severe Mac’s cardiopulmonary distress was during an office visit three weeks prior to his death. The doctor disputed the allegations to the Chicago Sun-Times, saying that he believes he treated Mac appropriately.
