The Police Receive the Tip-Off
It wasn’t until 2020 that the Chinese police received any leads regarding Yin’s kidnapping. They were given a tip that a kidnapped child had been brought from Shaanxi to the Sichuan province somewhere around the late 80s.
The police then set to work. They used facial recognition software to create an image of what the child would look like right now. As it turns out, the image that was drawn up happened to strike a match.
