In the afternoon of the same day, the Yaoming Police Station, the temporary office of the Special Investigation Group.

Zhao Yuzheng was standing in front of the whiteboard analyzing the case, and in addition to Wu Xiumin and others, there were also Wang Can's team and representatives of another special investigation team in the room.

"Master," after Zhao Yu finished talking about the latest situation, Wang Can put forward his opinion, "After 23 years, Liu Cheng is a mentally ill person again, is his words credible?"

"Credible!" Zhao Yu said with great certainty, "It is precisely because he is a mentally ill person that he remembers it more clearly than ordinary people!"

Moreover, in order to prove it, he also told me in detail about the situation back then, and he even remembered the police number of the criminal police who handled the case at that time!

"So, I don't think he will be mistaken, the murderer of the case in the nursing home is very likely not Nong Zhifa at all!"

"No......" Cui Lizhu pouted, "Who else could it be?" Nong Zhifa wrote a murderous memoir, if he wasn't the murderer, how could he know so many details?"

"Even if it's not him," Wu Xiumin analyzed, "The relationship between the real murderer and Nong Zhifa must be extraordinary! 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 is this happening, is it ...... Isn't the real murderer of the murder memoir Nong Zhifa?

"But...... How can you explain the cases that have already been compared?"

"Hmm......" Zhao Yu pondered for a long time, but did not speak.

Wang Can said: "If we analyze the data, I'm afraid we can only draw one conclusion, right?

"Nong Zhifa may also have a like-minded accomplice, and the 13 cases in the murder memoirs may have been completed by the two of them separately!

"Then, the two of them shared, and finally Nong Zhifa wrote a memoir!" Wang Can analyzed, "In this way, the situation of inconsistent trajectories can be explained clearly."

"When Nong Zhifa went to the northeast, his accomplices still stayed in the southeast...... This case should have been done by the two of them, no wonder, there are differences in the way of killing people in these cases!

"The police never considered that these people were committed by serial killers!"

"No, I don't think so!" Who knows, Zhao Yu suddenly raised an objection and asked Wang Can, "Take the case of the nursing home, although there are eyewitnesses, the police only found shoe prints, don't you think, there is any problem?"

"What's the problem?" Not only Wang Can, but everyone was puzzled.

"The murderer didn't wear a hood, he was seen by Liu Cheng, and then he left footprints," Zhao Yu said, "So, at first glance, this case looks like the murderer's temporary idea, that is, he saw a woman going to the toilet in the middle of the night, so he went in and raped and killed her!"

"But ......" Zhao Yu spread out his hands, "I have read the case records, what about fingerprints? No! What about Jingye? No! I don't understand, what is the situation? There is no essence, how can I determine the strong tip?"

"That's the case...... Wang Can hurriedly replied, "It was determined by the forensic doctor through the characteristics of the victim, and at that time, paraffin wax and propylene glycol and other ingredients were detected, which proved that the murderer should have brought a condom!"

"What about the hair?" Zhao Yu said again, "I didn't get the essence, but in such a drastic situation, didn't the murderer even lose a single hair?"

"This ......" Wang Can was speechless.

"There are only two reasons for this," Zhao Yu stretched out two fingers, "First, it was the mistake of the technical team that year and did not collect suspicious hair;

"......" everyone listened attentively, and the room was silent.

"If it's the former, maybe it's understandable!, but ......," Zhao Yu said, "if it's the latter, then this matter is not so simple!"

"That shows that the murderer didn't come on the spot at all, but came prepared!" Zhao Yu said extremely hard, "Think about it, this murderer's behavior seems to be bold and crazy, but the whole crime process is so careful, this is the most terrifying part of this case!"

"This ......" everyone was trying their best to keep up with Zhao Yu's rhythm.

"The murderer knows about our police's procedures," Zhao Yu said, "He knows that leaving a footprint alone is not a big problem!

Looking at Nong Zhifa's murder memoir, although his description of this sanatorium murder case is consistent with the scene of the crime, he did not mention a word about these hidden details!

"So, I have reason to suspect," Zhao Yu said astonishingly, "Nong Zhifa was just used, and about the murder memoir case, it is very likely that there is another real murderer !!"

Swish......

After Zhao Yu finished speaking, there was silence in the office, and everyone felt a cool air coming out of their backs.

After a long time, Cui Lizhu was the first to speak: "Boss, this is also ...... If there is someone else, then Nong Zhifa ...... What's going on?"

"The real murderer may have seen Nong Zhi's terminal illness, so he promised him some benefits, let him take the bag for himself, and be this murderous serial killer!

Or......

"But ......," Ran Tao objected, "If Nong Zhifa hadn't taken the initiative to say it, I'm afraid no one would know about the murder memoirs, right?"

"Yes...... Wang Can pondered, "is it...... Was it at that time 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 found it earlier, maybe it wouldn't have been so troublesome!"

"I can't say the specific situation," Zhao Yu said, "My inference itself is not reliable, but we can extend along this line of thought!"

"Now, after all, we have Liu Cheng as a breakthrough," 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 to Liu Cheng for identification!"

"If Liu Cheng can identify it, then this case may be able to end in the simplest way!"

"Good idea!" Ran Tao clapped his hands and hurriedly beckoned to Zeng Ke, "Xiao Zeng, let's do this matter!"

"Well, let's do it with me!" Wang Can took the initiative to ask, "A few days ago, in order to do a good job in the investigation, we have already collected information, so it is more appropriate to leave this matter to me!"

"It's just ......," Wang Can said worriedly, "Liu Cheng is a mentally ill person after all, but it took 10 days for Master to let him open Chrysostom, and we ......."

"It's okay," Zhao Yu said, "I have already found the root of Liu Cheng's disease, and after the expert intervenes, I believe that Liu Cheng can be solved!"

"Okay, then I'll rest assured!" After Wang Can nodded, he didn't forget to pat his ass, "Master is Master, not only is he a master who solves cases, but he can even solve cases with mental patients, which is really an example for us to learn!"

"You kid," Zhao Yu pointed at Wang Can, nodded with a smile and said, "Why haven't you grown up at all?" I'm an international detective, you still have a lot ......to learn in the future!
