A 71-year-old man collapses at home and is dead on arrival at the hospital. The doctor at the hospital refuses to sign the death certificate due to no apparent cause of death, so the body is sent to the morgue for an autopsy. Dr. G first suspects a cardiac death, but then discovers that the man had a toe infection and was taking antibiotics that caused adverse side effects. Because of the man's complex medical history, Dr. G decides that an autopsy is necessary to determine the cause of death. A 25-year-old man is found dead in a motel room after a night of partying and heavy drinking with friends. The man had a history of unexplained grand mal seizures and was obese, but Dr. G suspects that the cause of death may be related to alcohol and/or cocaine use.
