Her neck aching after a night of wrapping gifts on Christmas Eve, Michelle Ferrari-Gegerson, MD, used an electronic massager to relieve the pain. That night, her lifeless body was found by her husband on the bedroom floor of their Miami area home. The culprit: the massager, say Broward Sheriff's Office detectives and the Medical Examiner's Office. They believe it got tangled in her necklace and strangled her. Ferrari-Gegerson, 37, worked as a radiologist in the emergency room of Jackson Memorial Hospital and was the mother of a 1-year-old, colleagues said. ?Last week she was here and she brought baked goods for various employees,? said Barbara Perez Deppman, director for radiology at the hospital. ?That's what type of person she was. Out of the blue, she would just give people food vouchers and take them out to lunch.?
