A mother who fought hard for her teenage daughter to stay on life support after being declared brain-dead nearly five years ago has said goodbye to her child. Jahi McMath died after a surgery in New Jersey on June 22, her mother, Nailah Winkfield confirmed Thursday. McMath’s story had reached people nationwide after the Oakland teen, who was 13 at the time, suffered severe brain damage during a routine tonsil surgery in California in December 2013, Time reported. The teen was said to be brain-dead by specialists after neurological tests were done, and a coroner signed a death certificate. Winkfield, however, put her faith to the test, refusing to accept doctors’ conclusions and committing to go to bat for her child to get continued medical care.
