Unlikely Suspects

Two trash bags are found in a swamp containing the dismembered body of a missing 27-year-old man. The man was last seen when he left his home to collect a debt from an acquaintance. The acquaintance becomes the prime suspect, and confesses the crime to his cellmate, but denies the crime to the police. It's up to Dr. G to uncover the truth. A 55-year-old man is seemingly run over by a slow-moving van backing out of a parking lot. Dr. G finds external evidence of trauma, but no apparent internal injuries. Dr. G must take this case under the microscope to determine the cause of death.
