Teacher Justine MacMurry is retiring from her job after more than 30 years at Meigs Middle Magnet School in Nashville, Tennessee. A celebration was held in her honor and students from throughout her past three decades teaching came to toast her. "You are absolutely one of the best," one student told WTVF. MacMurray recently was diagnosed with cancer and still has 10 months left of chemotherapy. Inside Edition Digital has her story.
