A Waterville woman has filed a medical malpractice lawsuit in Lucas County Common Pleas Court against a ProMedica physician and several facilities claiming that staff failed to provide proper medical care, leading to the death of her newborn son. Kaley Cocoran filed the complaint Jan. 29 on behalf of herself and the estate of her late son, Brady Gaghen, against obstetrician and gynecologist Dr. Dayna Mohammadione, along with ProMedica Toledo Hospital, ProMedica Physicians Obstetrics, and ProMedica Physician Group. The baby died on Aug. 14, according to court records.
