The wife of the late comedian Bernie Mac has dropped a wrongful death lawsuit against his Chicago doctor.

Rhonda McCullough alleged in the lawsuit that dermatologist Rene Earles failed to recognise signs of respiratory distress in the weeks before Mac’s death in 2008 from pneumonia.

McCullough’s attorney, Cannon Lambert Sr, said the lawsuit can be refiled later after “internal issues” are shored up. He did not elaborate.

Earles’ attorney, Mike Prangle, told the Chicago Tribune the lawsuit was dismissed on January 15 because McCullough “had no legitimate case against Dr Earles.”

Earles treated Mac for more than a decade for the lung disease sarcoidosis, which causes inflammation of the body’s tissues.

Born Bernard McCullough, Mac starred in the movie Ocean’s Eleven and the sitcom The Bernie Mac Show.
