Fatal Twist

A 49-year-old pilot is found dead in the burning wreckage of his plane. The results of an autopsy will help the National Transportation Safety Board to determine what caused the plane to crash, so Dr. G must look for factors that may have caused pilot error, such as natural disease, drugs, or alcohol. A 44-year-old woman is found dead in her apartment, face down in a pool of blood. Police suspect that the woman's boyfriend fatally assaulted her, but the boyfriend denies the accusations. Will Dr. G's autopsy clear the boyfriend, or confirm the police's suspicions?
