An old man with his left leg amputated hanged in his apartment and was discovered a day later. The body was about 80 centimeters from the ground. There was no footing on the ground, and the old man only had one leg. It was impossible for him to jump up and put the rope around his neck.
The old man had taken out a high-cost life insurance two months before his death. Judging from the scene, the door was locked from inside the house, making it look like a secret room. The insurance company suspected that the deceased had committed suicide in order to defraud insurance, so they called the police.
The police came to the scene. An empty paper packaging box was found under the body. Suddenly, the police had an idea and quickly concluded that the old man had disguised his suicide as homicide.
