A four-month-old baby is found unresponsive in his crib, and cannot be revived at the hospital. Dr. G must investigate the possibility of child abuse as she searches for the cause of death. A 36-year-old woman has a seizure and dies on a city bus. The woman had gone to the hospital the night before, complaining of chest pain and lightheadededness, and had been diagnosed with bronchitis. Also of concern is that the woman lived in a group home for the mentally disabled. Was the woman a victim of neglect or foul play in the group home, did the hospital make a fatal misdiagnosis of her condition, or did she die from something else entirely? It's up to Dr. G to find out.
