It was ten minutes late at night, inside the office of Chengzhou Police Department.

"This is..." Zhao Yu looked at the several whiteboards of the case erected in the office and asked, "Who did this? It seems that it's about to catch up with me!"

"Of course I made it, boss," Choi Lizhu joked, "I have learned the essence of you. Can you get a master now?"

"Well... not bad, not bad..." Zhao Yu sincerely praised, "No more, your face is definitely more thick than mine!"

"Go to yours..." Cui Lizhu despised her head and said, "Liu Yishi's identity is very special. Given that there is no evidence to prove that he is the suspect, we cannot formally arrest him!

"He can only be allowed to stay in the police station for the time being and assist the police in investigating..."

"So...what is his wife?" Ran Tao asked, "Didn't the boss doubt that his wife has anything to do with this matter?"

"I'm afraid... well..." Choi Lizhu said, "This case has nothing to do with his wife, we just think too much!"

"Why?" Ran Tao asked hurriedly.

"We have checked the information. Liu's only wife, Nie Ya, is now a senior director of the TV station," Cui Lizhu explained. "This person has a very outgoing personality. He has directed many large-scale performances in Heyang Province and is a meritorious figure.

"And, putting aside her character," Cui Lizhu sank for a moment and said, "She weighs only 81 kilograms, she is a beautiful woman with no power to tie a chicken!

"I found the information. She was still light when she was in school. It is said that she couldn't even lift the battery of an electric car... How could such a person hide four bodies in the garbage path? How could he dig a deep pit more than two meters from the big banyan tree?"

"Yes," said Wu Xiumin, "through superficial data analysis, Nie Ya should not be suspicious! Unless... this matter was done by the couple together!

"But, I just asked their classmates," said Wu Xiumin. "They have confirmed that what Liu Wei said is true. In the first half of the semester of freshman and sophomore, Liu Wei and Nie Ya were indeed separated, and they didn't even say anything!"

"I think..." Miao Ying analyzed, "Although Liu Yishi said it perfectly, we do not have 100% evidence to prove that he is not the murderer of this case!

"So, we still have to treat Liu Yishi as the first suspect," Miao Ying said. "The manuscript and essay matters may be compiled by him! He deliberately wanted to pull our attention away from him!"

"Sister Miao," Unexpectedly, as soon as Miao Ying finished speaking, Zhang Peipei, who had just entered the office, suddenly spoke, "It sounds like he is a little intentional, but after the test, Liu's suspicion has been ruled out!

"After inspection, the dander tissue we found on the body bag and tape did not match Liu's biological information, so the real murderer should not be him!"

"oh……"

Hearing Zhang Peipei's words, the scene fell silent. From this point of view, there was indeed a real murderer in this murder diary!

"But..." Ran Tao suddenly raised an objection, "What if... Liu is the only expert like Han Kuan, who is more familiar with the police's methods of handling cases?

"Liu Yiu has done precise protection in advance and left no information.

"And the dander we found was just something that happened to be left behind by someone else, not the murderer himself?"

"You think it's a bit too complicated," Zeng Ke said. "In that era, although DNA technology had been invented, it was not popular abroad. For us, there were even fewer people who knew about it!"

"This is not necessarily true," Ran Tao insisted on his opinion, "knowing little does not mean there is no one! What if Liu Yiwei is confident!

"He was sure we couldn't find anything that could convict him, so he compiled such a story..."

"I have paid close attention to Liu Wei," said Wu Xiumin. "No flaw was seen. If this person is really lying, then he must be a top psychologist, even better than a professionally trained agent!"

Wu Xiumin suddenly mentioned lying, and Zhao Yu thought of the invisible lie detector at the first time. Unfortunately, the lie detector was gone after the last time he was used.

Moreover, his feelings were the same as Wu Xiumin. He also believed that Liu Yiwei and Han Kuan were different and did not have such a deep cunning life, so he should not have lie!

"That's it!" Zhao Yu said, "Instead of making meaningless guesses, it's better to let the facts speak! Next, let's take action separately and take some real skills!

"Cui Lizhu," Zhao Yu was the first to say to Cui Lizhu, "You are responsible for investigating Liu Wei's past to see if his words are true, and whether he really hadn't been to school during that summer vacation that year!

"Also, his wife Nie Ya also investigated and dug out the detailed information of the couple!"

"Yes!" Cui Lizhu nodded firmly and decisively.

"Sister Wu," Zhao Yu ordered Wu Xiumin again, "You go and investigate the situation of Liu's class group and find out the person who posted internal police information. This person may have an important relationship with this case!"

"I understand," Wu Xiumin nodded, "I'm already investigating this person! It is said that the three girls in their class heard the news at the dinner table. I am pursuing it now, and I'll probably find the source soon!"

"Okay!" Zhao Yu nodded and said to Ran Tao and Captain Mou, "Brother Tao, you and Captain Mou go find Liu's classmate, investigate their identity information one by one, and see if there are anyone who matches the dander tissue on the tape!

"Remember, master a principle from near to far," Zhao Yu reminded, "start with Liu Yiwei's closest relationship first, and then slowly expand the scope!"

"I understand! Don't worry!" Ran Tao received the order.

"Zeng Ke," Zhao Yu said to Zeng Ke again, "You stare at the 3D image and immediately issue a corpse search revelation after you have done it!

"Also, together with Forensic Doctor Zhang, you should carefully check these corpses. The most important task at present is to find out the identity of the deceased!

"Just before, although DNA has not found a match, gene comparison can be performed, and the genetic status of the victim is first clarified and see where they are... "

"I understand!" Zeng Ke nodded, "Leave it to me..."

After assigning the task, Zhao Yu first looked at the whiteboard, and then said to Captain Mou: "Captain Mou, the person who tied the bell must be untied. You should always pay attention to the school news and let the school cooperate with our investigation!

"Also, if there is no major progress in the case tomorrow, please help me find all the parties involved in the school, and I want to have a good talk with them..."

"Oh, OK, no problem!" Captain Mou quickly saluted.

After giving all the instructions, Zhao Yu turned around and said to Miao Ying: "Team Leader Miao, follow the old rules, you can watch the media and public relations!

"The case has been exposed by the media. Now Heyang Normal University has been on the hot search list, so we need to deal with many details carefully. It would be impossible without you!"

"You..." Miss Miao pointed helplessly at Zhao Yu's ear, and then said, "There is no problem with these things, but you have to pay attention to your physical condition!"

"Haha, don't worry!" Zhao Yu took the opportunity to hold Miao Ying's shoulder, "I'm a crazy detective, this little thing doesn't matter, come on...
Chapter completed!
