In the afternoon of that day, the temporary office of the special task force of Yaoming Police Station.
Zhao Yu was standing in front of the whiteboard and analyzing the case. In addition to Wu Xiumin and others, there were also Wang Can's team and representatives of another special investigation team who were discussing the case together in the room.
"Master," Wang Can put forward his own opinion after Zhao Yu finished explaining the latest situation, "After 23 years, Liu Cheng is a mental patient again. Can his words be trusted?"
"Believable!" Zhao Yu said with great certainty, "Just because he is a mental patient, he remembers it more clearly than ordinary people!
"And, to prove it, he told me the situation in detail, and he even remembered the police number of the criminal police officer who handled the case at the time!
"So, I think he will remember correctly. There is a high possibility that the murderer in the nursing home case was not Nong Zhifa at all!"
"No..." Cui Lizhu pouted, "Who else could it be? Nong Zhifa wrote a murder memoir. If he was not the murderer, how could he know so many details?"
"Even if it wasn't him," Wu Xiumin analyzed, "the relationship between the real murderer and Nong Zhifa must be unusual! Perhaps, these details were told to Nong Zhifa by the real murderer!"
"Boss," Ran Tao next to him asked Zhao Yu, "What do you mean? Why does this happen? Could it be that... the real murderer in the Memoirs of Murder is not Nong Zhifa
"But...how to explain the cases that have been compared?"
"Well..." Zhao Yu thought for a long time, but didn't speak.
Wang Can spoke up: "Based on data analysis, I'm afraid we can only draw one conclusion, right
"Nong Zhifa may have a like-minded accomplice. The 13 cases in the murder memoirs may have been completed by the two of them separately!
"Then, the two people shared it, and Nong Zhifa finally wrote the memoir!" Wang Can analyzed, "In this way, the inconsistency in the trajectories can be explained clearly.
"When Nong Zhifa went to the Northeast, his accomplices were still in the Southeast... This case should have been committed by two of them. No wonder there are differences in the killing methods in these cases!
"The police have never considered that these people are serial killers!"
"No, I don't think so!" Unexpectedly, Zhao Yu suddenly raised objections and asked Wang Can, "Take the case of the nursing home. Although there were witnesses, the police only found shoe prints. Don't you think so? ,Any questions?"
"What's the problem?" Not only Wang Can, but everyone was confused.
"The murderer didn't wear a hood, and Liu Cheng saw his face, and then left footprints," Zhao Yu said. "So, at first glance, this case looks very much like the murderer's impromptu idea. He saw a woman going to bed in the middle of the night. toilet, so go in and rape and kill him!
"But..." Zhao Yu spread his hands, "I've read the case records. Where are the fingerprints? No! Where's the sperm? No! I don't understand, what's going on? There's no sperm, how can you determine the strong point?" "
"That's right..." Wang Can quickly replied, "The forensic doctor determined it based on the characteristics of the victim. Moreover, ingredients such as paraffin and propylene glycol were detected at the time, which proved that the murderer should have worn a condom!"
"Where's the hair?" Zhao Yu asked again, "I didn't get sperm, but in such a violent situation, didn't the murderer even lose any hair?"
"This..." Wang Can was speechless.
"There are only two reasons for this situation," Zhao Yu held out two fingers. "First, the technical team made a mistake and did not collect the suspicious hair; second, the murderer took strict protective measures and shaved it off in advance. His hair down there!”
"..." Everyone listened carefully, and the room was quiet.
"If it's the former, maybe it's easy to understand! But..." Zhao Yu said, "If it's the latter, then this matter is not that simple!
"That means the murderer didn't act impromptu at all, but came prepared!" Zhao Yu said with great force, "Think about it, this murderer's behavior seems bold and crazy, but the entire crime process is so careful. This is The scariest part of this case!”
"This..." Everyone was trying their best to keep up with Zhao Yu's rhythm.
"The murderer understands our police's case handling procedures," Zhao Yu said. "He knows that just leaving a footprint is not a big problem! But sperm, fingerprints, and hair cannot be left behind!
"Looking at Nong Zhifa's murder memoirs again, regarding the nursing home murder case, although his description was consistent with the crime scene, he did not mention a word about these hidden details!
"So, I have reason to suspect," Zhao Yu said astonishingly, "Nong Zhifa was just being used. As for the murder memoir case, it is very likely that there is a real murderer!!!"
Whoa…
After Zhao Yu finished speaking, there was silence in the office, and everyone felt a chill coming from their backs.
After a long time, Cui Lizhu was the first to speak out: "Boss, this is... incredible, isn't it? If the real murderer is someone else, then what happened to Nong Zhifa...?"
"Perhaps the real murderer saw that Nong Zhi was seriously ill, so he promised him some benefits and asked him to take over for him and become this brutal serial killer!
"or… "
"But..." Ran Tao objected, "If Nong Zhifa hadn't taken the initiative to speak out, no one would have known about the murder memoirs case, right?"
"Yeah..." Wang Can pondered and said, "could it be... that the murderer found out that he had been exposed, so he found Nong Zhifa as a scapegoat?"
"It's a pity that Nong Zhifa is dead... Alas!" Ran Tao sighed, "If I could have discovered it earlier, maybe it wouldn't be so troublesome!"
"I can't tell you the specific situation," Zhao Yu said, "My inference itself is unreliable, but we can extend this idea!
"Now, after all, we have Liu Cheng as a breakthrough point," Zhao Yu pointed to Liu Cheng's photo on the whiteboard, "Since Liu Cheng has seen the real murderer, then we will take the photos of all the people related to Nong Zhifa. Go and identify Liu Cheng!
"If Liu Cheng can identify it, then this case may be ended in the simplest way!"
"What a great idea!" Ran Tao clapped his hands and quickly waved to Zeng Ke, "Xiao Zeng, let's handle this matter!"
"Well, let me do it!" Wang Can volunteered, "A few days ago, in order to do a good job in the investigation, we have collected information, so it is more appropriate to leave this matter to me!
"It's just..." Wang Can said worriedly, "Liu Cheng is a mental patient after all. It took Master 10 days to get him to open his mouth. We..."
"It doesn't matter," Zhao Yu said, "I have found the root cause of Liu Cheng's disease. Once the experts intervene, I believe I can cure Liu Cheng!"
"Okay! Then I'm relieved!" After Wang Can nodded, he didn't forget to flatter him, "Master is master. Not only is he great at solving crimes, he can even deal with mental patients. He is really an example for us to learn from!"
"You kid," Zhao Yu pointed at Wang Can, nodded with a smile, "Why haven't you improved at all in your ability to praise others? I am an international detective, and you still have a lot to learn in the future! Hahaha..."
