Harbin meat grinder case, 10 accompanying maid was killed six times. How was the murderer caught by the police?

Harbin meat grinder case shocked the whole country. The criminal acts of Yang Shubing and Zhang Yuliang are outrageous. They started from 1992. At first they robbed and didn't kill people, but later their whereabouts were exposed. Since then, Yang Shubing has learned his lesson. In order not to expose the crime, he will not leave any survivors. The means are extremely cruel. He committed six crimes, killed all the victims and brutally dismembered them with a meat grinder.

Their crime goal is to accompany maids who wander around cities. The maid is rich, even if she disappears, no one cares. Before committing the crime, they rented a high-end house nearby, and there must be a big bathtub in the house to decompose the body. Yang Shubing dressed up as a rich man and went to high-end entertainment clubs to spend a lot of money catching prey. After the victim was lured to his own residence, he was kidnapped and extorted money, and then he was killed. He crushed the bones with pliers, crushed the body with a meat grinder, and then rushed into the sewer.

In Jilin in 2002, when they dismembered the bodies, people saw floating black and yellow bodies and smelled unbearable stench because the drainage pipes were in disrepair for a long time. This made people around you suspicious. When the police arrived at the crime scene, they were shocked to see dismembered bodies and fingerprints everywhere. Yang Shubing and others had already escaped, and then disappeared. They and their relatives can't be found in the household registration. It turned out that they all changed their names again and went to Baotou to settle down with a dozen relatives.

When I arrived in Baotou, I suddenly became a businessman. They are very particular about their whereabouts, never staying in hotels, never flying, never leaving any fingerprint clues, and usually don't go back and forth, just visiting during the New Year. 10 years later, the case has not been solved, but Xu Jianguo, one of Yang Shubing's parents, became a policeman and was responsible for investigating the case. After he found the photo of Yang Shubing according to the fingerprint clue, he chased it all the way to Baotou, became a citizen, investigated the whereabouts of the four of them and arrested them. Finally, all four were arrested and confessed to the facts of the crime. Mills of God grind slowly but sure.
