After investigation, the police quickly confirmed the identity of Tao Yufen. She was one of the first batch of demolition households in the East District of Old City.Tao Yufen's boyfriend, Chi Yong, worked at an amusement park. When police asked about her whereabouts, Chi Yong claimed that Tao Yufen told him that she was going to a friend's house and would not come back.However, the police told him that Tao Yufen had been killed and took him to the police station for investigation.Chi Yong was very sad after hearing this, and then followed the police to the police station to cooperate with the investigation.

At the police station, Lu Xingzhi and Wei Zhengrong contacted Tao Yufen's family members to learn more valuable clues.Wei Zhengrong only stated the facts objectively based on the existing evidence, while Lu Xingzhi believed that Chi Yong had a motive and time for the murder, but was not the murderer of the first two female victims because the circumstances of their killing were very different from Tao Yufen.At this time, the medical examiner stated that the tragic deaths of the three women were all caused by being hit on the head with a blunt instrument, but Tao Yufen was killed with the most force.

At the same time, Lao Zhu visited Tao Yufen's friends and reported the situation to Wei Zhengrong.Clues about the amusement park also emerged. Chi Yong took half an hour's leave, which aroused police suspicion.Lu Xingzhi started to simulate and found that if he rode a bicycle back and forth between the amusement park and the dumping place, half an hour was not enough, so his method of committing crimes was extremely suspicious.

In order to find out the truth, the master and the apprentice searched around, and finally found a woman's clothes with blood stains on an abandoned haunted house.Next, Wei Zhengrong and Lu Xingzhi interrogated Chi Yong again, and Chi Yong finally admitted that Tao Yufen's case was his own fault, and he did not know about the other two.

Despite this, Wei Zhengrong still did not believe Chi Yong's confession, especially as to why Chi Yong put down his pencil, but Chi Yong claimed that this was just an unintentional decision on his part.As the investigation continued, colleagues found a pair of shoes at Chi Yong's home and sent them to Master Lu for comparison.It turned out that the shoes were exactly the same as the shoe prints left at the crime scene, which aroused great suspicion among the police.

Then, Wang Li from the playground took the initiative to reveal that Chi Yong had threatened that she would become the third victim and guided the police to conduct further investigations.Lu Xingzhi found the hidden clothes in a place mentioned by Wang Li, which once again proved that Chi Yong was the suspect of the first two victims.Later, Chi Yong admitted to the police that he had killed Liu Meng and Du Mei, and described his crime process.

However, Lu Xingzhi still believed that Chi Yong could not be the murderer of Tao Yufen because all the evidence showed that he did not have such ability, but Wei Zhengrong had a different view on this.As a result, the two started a fierce quarrel again.

Neither the master nor the apprentice gave up. They both continued to search for clues and accidentally discovered a photo of a crowd at the scene of the crime. There was a woman in red with the same red hair color, so the two understood each other tacitly.I thought of Chi Yong's colleague Wang Li. Her features fit the person in the photo very well.
