A 32-year-old man collapses and dies at his sister's home. The man had been feeling sick for a week prior to his collapse. Dr. G has no medical records to go on, as the man did not go to the doctor, but his external appearance indicates that he was in extremely poor health. Dr. G suspects that the man's self-neglect may have played a role in his death. A 49-year-old father is found dead in his kitchen with multiple stab wounds. The man's teenage son claims that his father stabbed himself to death, but the police suspect that the son was responsible. It's up to Dr. G to determine if the death was a suicide or a homicide.
