Yandere, how did his father die?

Ning Hao and Wu Anshun jointly committed the crime.

The key issue that needs to be solved in the father's case is the order of the three videos. It seems that the deceased locked the door and then stepped on a chair to hang himself. In fact, the murderer disrupted the order of the videos, causing misleading. The following is Here are the steps:

① Enter the room with the key, put the hemp rope around the neck of the deceased, and tie a one-way tight knot (note: the father is 1.8m tall, the video is 1.5m, and the father cannot be seen noose around the neck).

②Put the other end of the hemp rope through the ceiling beam, then through the window and out the door.

③Use a saw blade to cut the key into a quick-breaking state, and then place it on the beam.

④ Go out of the room, lock the door from the outside with the spare key, then go around to the window and wait.

⑤ Wait for the deceased to wake up, take a video with your mobile phone, and adjust the angle so that the deceased’s neck and above cannot be photographed, otherwise the hemp rope will be photographed.

⑥The deceased woke up and found that the hemp rope was tied around his neck and could not be untied, so he immediately wanted to open the door. At this time, I found a key on the beam, so I moved a chair and stepped on it.

⑦The deceased went to open the lock after getting the key, but because the key had already been sawed in half, it was broken with force and half of the key was stuck in the lock core.
