DOA. Pt was a 26 Y.O. F. She was found prone lying submerged in a bathtub of water. Body was warm with no signs of rigor. Autopsy states that she had a bruise on the front of her head with no cerebral hemorrhage. Pt had signs of Pulmonary Edema, Cardiomegaly, and bilateral ventricular atrophy. Pt does have a hx or cocaine abuse and toxicology said she had cocaine in her blood. My question- was she murdered, or was it the cocaine, and why?
