In the afternoon, in the temporary office of the Special Investigation Group in the Yaoming Police Station …
Zhao Yu was standing in front of the whiteboard, analyzing the case. In addition to Wu Xiumin and the others, Officer Wang's team and another representative of the Special Investigation Group were also discussing the case.
"Master," Officer Wang said. "After 23 years, Liu Cheng is a mental patient again. Can his words be trusted?"
"Yes!" Zhao Yu said with certainty. "Because he is a mental patient, he remembers things more clearly than ordinary people!
And, in order to prove it, he told me in detail what happened that year. He even remembered the police number of the criminal police who handled the case at that time!
So, I don't think he is mistaken. The murderer of the sanatorium case is very likely not Nong Zhifa at all! "
"No …" Cui Lizhu pouted. "Who else could it be? If Nong Zhifa isn't the murderer, how could he know so many details in his memoirs? "
Wu Xiumin said, "Even if he is not the murderer, the real murderer must have a special relationship with Nong Zhifa! Maybe the real murderer told Nong Zhifa all these details! "
"Boss, what do you think?" Ran Tao asked Zhao Yu, "Why did this happen? Why did this happen? Could it be that … the real murderer of the Memoirs of Murder was not Nong Zhifa?
But … How do you explain the cases that have been compared? "
"Um …" Zhao Yu thought for a long time, but did not speak.
Officer Wang said, "If we analyze the data, I'm afraid we can only come to one conclusion.
Nong Zhifa may have a like-minded accomplice. The 13 cases in the memoirs may have been completed by the two of them separately! "
Officer Wang then said, "Then, the two of them shared the information, and Nong Zhifa wrote the memoirs! In this way, we can clearly explain the inconsistencies in the trajectories."
Officer Wang then said, "When Nong Zhifa went to the northeast, his accomplice was still in the southeast. This case must have been committed by the two of them. No wonder there are differences in the killing methods in these cases!
The police never considered that these people were the work of a serial killer! "
"No, I don't think so!" Zhao Yu suddenly raised an objection and asked Officer Wang, "Take the case of the sanatorium as an example. Although there were witnesses, the police only found shoe prints. Don't you think there's something wrong?"
"What's the problem?" Not only Wang Can, but everyone was also puzzled.
"The murderer didn't wear a mask, so Liu Cheng saw his face and left footprints," Zhao Yu said. "So, at first glance, it looks like the murderer came up with the idea on the spur of the moment. He saw a woman going to the toilet in the middle of the night, so he went in to rape and kill her!
"But …" Zhao Yu spread out his hands. "I've seen the case records. Where are the fingerprints? No! Where's the essence? None at all! I don't understand. What's going on? You don't even have any essence, so how can you determine how strong he is? "
"It's like this …" Officer Wang quickly replied, "It was determined by the forensic doctor based on the victim's characteristics. Moreover, paraffin and propylene glycol were detected at that time, which proved that the murderer should have worn a condom!"
"Where's the fur?" Zhao Yu asked again, "He didn't get the essence, but in such a violent situation, the murderer didn't even lose a hair?"
"This …" Officer Wang was speechless.
"There are only two reasons for this situation." Zhao Yu held out two fingers. "First, the technical team made a mistake that year, as they didn't collect any suspicious hair. Second, the murderer took strict protective measures and shaved off his lower body hair in advance!"
Everyone listened carefully, and the room was silent.
"If it was the former, it might be understandable! But … "Zhao Yu said," If it was the latter, then this matter is not so simple!
"That means that the murderer didn't come up with the idea on the spur of the moment, but came prepared!" Zhao Yu said with great force. "Think about it, the murderer's behavior seems bold and crazy, but the whole process of committing the crime is so meticulous. This is the most terrible thing about this case!"
"This …" Everyone was trying to keep up with Zhao Yu.
"The murderer knows our police procedure," Zhao Yu said. "He knows that leaving a footprint is not a big problem! But, he can't leave the essence, fingerprints, and hair! "
Zhao Yu then added, "Looking at Nong Zhifa's Memoirs of Murder, although his description of the murder in the sanatorium is consistent with the crime scene, he didn't mention these hidden details!
"So, I have reason to suspect that Nong Zhifa was just used by someone. As for the Memoirs of Murder, it is very likely that there is a real murderer!"
Swish …
After Zhao Yu finished speaking, the office was silent. Everyone felt a chill run down their spines.
After a long time, Cui Lizhu was the first to speak. "Boss, this is unbelievable! If the real murderer is someone else, then what's going on with Nong Zhifa? "
"Maybe the real murderer saw that Nong Zhifa was seriously ill, so he promised him some benefits and asked him to be the scapegoat for him.
"Or …"
"But …" Ran Tao objected. "If Nong Zhifa hadn't taken the initiative to say it, I'm afraid no one would have known about the Memoirs of Murder case."
"Yes …" Officer Wang pondered and said, "Could it be that the murderer found out that he had been exposed, so he used Nong Zhifa as a scapegoat?"
"It's a pity that Nong Zhifa is dead … Alas!" Ran Tao sighed. "If it had been discovered earlier, maybe it wouldn't have been so troublesome!"
"I'm not sure about the specific situation," Zhao Yu said. "My inference itself is not reliable, but we can follow this line of thought.
"Now, after all, we have Liu Cheng," Zhao Yu said, pointing to Liu Cheng's photo on the whiteboard. "Since Liu Cheng has seen the real murderer, we can take all the photos of people related to Nong Zhifa and let Liu Cheng identify them!
"If Liu Cheng can identify it, then this case can be concluded in the simplest way possible!"
"Good idea!" Ran Tao clapped his hands and waved at Zeng Ke. "Zeng, let's do this together!"
"Well, let me do it!" Officer Wang volunteered. "A few days ago, in order to do a good job in the investigation, we collected information, so it's more appropriate for me to handle this matter!
"But …" Officer Wang said worriedly, "After all, Liu Cheng is a mental patient. It took Master 10 days to get him to talk. We …"
"It doesn't matter," Zhao Yu said. "I have found the root cause of Liu Cheng's illness. When the experts intervene, I believe that Liu Cheng can be cured!"
"Good! That's a relief! " After Officer Wang nodded, he did not forget to flatter Zhao Yu. "Master, you are not only good at solving cases, but you can even handle mental patients. You are really a role model for us to learn from!"
Zhao Yu pointed to Officer Wang, nodded with a smile, and said, "Why haven't you improved at complimenting people? I am an international detective, and you have a lot to learn in the future! Ha ha ha … "
