At half past five in the afternoon, in a residential building in Xinghai District, Yaoming City, more than a dozen police officers were carefully searching for Tu Qiang's residence.

This is an old-fashioned residential building of only 70 square meters, and due to Ms. Xie's irregular maintenance, although it has been uninhabited for two years, it has always been kept clean and tidy.

More than a dozen police officers, all of whom were professional investigators transferred by Wang Can from the technical team and the forensic department, ensured that no clues would be missed.

Zhao Yu believes that if Tu Qiang is the real murderer X who killed 13 victims, then maybe there will be some evidence of guilt left in his home.

If any evidence related to the murder memoir can be found, then Tu Qiang can be made to bow his head and confess.

At this moment, Zhao Yu was standing in the living room of Tu Qiang's house, carefully observing the environment here.

Through preliminary observations, he can determine that Tu Qiang is indeed a person who loves to read books.

On his bookcase, in addition to a large number of books on law, there are many other professional books, such as psychology, pathology and even criminal investigation, etc., which can be described as a well-read book.

Moreover, Tu Qiang is a very careful person, every book is kept very complete and clean, and when you open the book, you can still see the neat notes he made.

This reminded Zhao Yu of Li Danlai who chopped the case, which shows that Tu Qiang is also a very scheming, cautious and cautious person, which is also very consistent with the character traits of the real murderer X.

All in all, after the investigation has been carried out so far, Zhao Yu has become more and more convinced that he is not looking for the wrong person, this Tu Qiang should be the real murderer X they are looking for, the real "Memoirs of Murder" is completely from his hands, and Nong Zhifa is just a scapegoat who has bewitched his mind.

"Master," Wang Can said to Zhao Yu with excitement on his face, "Ms. Xie said that although Tu Qiang had only lived in this old house for about a year before he was imprisoned.

"However, the things here are basically their old things!

"Oh ......" he opened his mobile phone and just checked the property information, "According to the information, this house was built in 97, and Tu Qiang and his wife bought a new house at that time and have been living here for five years."

"And during that period, the murder memoirs were not over, so maybe we could really find something! As long as we can establish contact with the victim, are we afraid that Tu Qiang's grandson will not confess?"

"But the key is ......," Zhao Yu said, "we must at least know what specific cases he committed during that time! The eight cases in the murder memoirs were all made up by him, and the five cases we can determine all happened 97 years ago!"

"Hmm...... Indeed......" Wang Can nodded and said, "Master, then...... Or else? I'm going to look up all the missing women of that era and see if they match the characteristics of a murder memoir?"

"This ......" Zhao Yu was slightly embarrassed.

"It doesn't matter," Wang Can said, "At the time of the initial investigation, the information had already been collected, but at that time we thought that the murder memoirs were all true!"

"Now, we just need to re-compare according to certain conditions," Wang Can behaved very positively, "At that time, we found a total of more than 400 missing cases, if the time node is shortened, then the workload will not be too large, we all have professional and technical personnel, we should be able to do it quickly!"

"Okay," Zhao Yu nodded, "If there is a little hope, we must also fight for it......"

"Okay! I'll do it......" After speaking, Wang Can picked up his mobile phone and went outside to make a call.

"Team leader, team leader......" At this time, Zeng Ke ran in from outside and reported to Zhao Yu, "There is news from the prison, and several prisoners have confirmed that Tu Qiang and Nong Zhifa have indeed had unusual exchanges......

"Damn!" Zhao Yu frowned, "We have all investigated these prisoners before, why didn't we say it before?"

"Hmm...... Possible...... Maybe there weren't any suspicious objects before, right?" Zeng Ke explained, "There is a lot of contact between prisoners and prisoners!"

"Then ......," Zhao Yu asked, "what kind of abnormal communication is it?"

The prisoners said that Nong Zhifa and Tu Qiang were both boring people in prison, and some people had seen that the two of them had close contact, as if they were ...... They talked very speculatively......

"Also, when they talk, they usually hide away from the crowd, and they seem mysterious and secretive......"

"Really?" Zhao Yu didn't believe it, raised his eyebrows and asked again, "Is there anything else?"

"No," Zeng Ke replied very seriously, "that's all! Actually, the prisoners said that they didn't have a lot of contact with these two because of their incompatible personalities......

"Alas!" Zhao Yu sighed, of course he understood that in and out of prison, the prisoners were like marquees, and it was reasonable that they didn't have much contact.

"Team leader......" Zeng Ke said again, "I just contacted Cui Lizhu, and the person is still interrogating, it seems that Tu Qiang is also out of the way, he is biting and refusing to speak, just betting that we can't find definite evidence!"

"Then let the prison authorities check him carefully," Zhao Yu instructed, "to see if there are any things related to the murder memoir in his personal belongings?"

"I've searched for it several times, but I haven't found it......" Zeng Ke shook his head.

"Hmm...... Also, this guy is so careful, even if there is evidence, it will be destroyed a long time ago!" Zhao Yu sighed, "Don't say, if we really can't find new evidence, then we have to watch him get away with it!"

"He's a lawyer, he knows that very well!"

"Yes!" Zeng Ke echoed while watching the work of the investigators, and proposed to Zhao Yu, "Team leader, if you want to get evidence, you have to find a way from elsewhere!"

"It would be nice if we could find what he committed back then!"

"Nonsense," Zhao Yu said, pointing at the searchers, "Otherwise, can I call so many people over?"

"I think ......," Zeng Ke added, "Tu Qiang didn't have more than one residence like this before, we should talk to that Ms. Xie again, and ask her to take us to find out more about Tu Qiang."

"Maybe you'll find something important?

"That's right!" Zhao Yu patted his thigh, his eyes lit up, and he hurriedly said, "I think so too, so please take a trip! This job will be left to you!"

"......" Zeng Ke grinned, but still nodded in agreement, "Okay, then I'll go and ask Wang Can for someone now......!

After speaking, Zeng Ke turned around and wanted to leave.

"Wait a minute," Zhao Yu stopped him again and said, "There is another task, which must be handed over to you and Wang Can to do!"

"Oh," Zeng Ke hurriedly asked, "what task?"

"Although the victims recorded in the memoirs of the murder were all randomly selected by the murderer, ......" Zhao Yu raised his eyebrows, "What if the murderer also made it up?"

"You...... What do you mean......" Zeng Keruo realized.

"You and Wang Can send someone to investigate Tu Qiang's interpersonal relationship," Zhao Yu said, "especially during the time period when the murder memoir occurred, see if there is anyone related to Tu Qiang, who has disappeared ......."
