A friend's death was classified as cocaine poisoning (i.e. overdose), due to 3.0 mg/L of benzoylecgonine in her blood, collected from the aorta post-mortem. The autopsy report said she had received a blow to the abdomen prior to death, causing a ruptured spleen and the loss of an estimated 500 cc of blood into her abdomen. The ME ruled cause of death as cocaine poisoning and the police did not question the person found with her about the blow to the abdomen. Given the level of cocaine her system, measured by the benzoylecgonine and 0.74 ecgonine methyl ester, was the blow to the abdomen and blood loss likely to be a contributing factor in her death? She had multiple bruises over her body as well. I know this is rather detailed, but the question has been nagging at me for a while.
