The sound was noisy, squeaky and buzzing, and it was played for a long time before the conversation began to be heard.

"You killed Zhou Guoqiang......"

“…… It's ......"

"After so many years, no matter how big the hatred is, it can be let go. We are old, and most of our bodies have been buried in the loess ......"

“…… No......"

"Wu Changan was also killed by you......"

“…… It's ......"

"Why ......"

“…… He...... Cyanogen...... ......"

It's staccato and inaudible, and the conversation is over here, followed by some loud bang, and then there's nothing at all.

Now, it is clear who the murderer is.

"It can basically be concluded that it was Li Chuang who killed Zhou Guoqiang and Wu Changan, and the person who died in the guard room was not Li Chuang but Cao Guisheng, and Li Chuang had already escaped." Wu Ping put the tape and letterhead back into the envelope bag and handed it to Liu Debao, "The charred ID card found under the body of the deceased was not snatched by Li Chuang from Cao Guisheng, but originally belonged to the deceased himself. ”

Li Chuang is the real culprit of the series of murders in Guangong Town Middle School. Xu You's purpose, to blame Li Chuang for Wu Changan's death, was achieved. Still, there was one thing he didn't expect.

As soon as Wu Ping and Liu Debao stepped into the door of the criminal police brigade, a female policeman greeted them with a smile, "Wu team, I have good news for you, we received a real-name report letter, written by a person named Yuan Man, who reported that Li Chuang killed Zhou Guoqiang and Wu Chang'an. ”

The female policeman's name is Lu Qingqing, who has just joined the company and is the daughter of Lu Anzhi, the political commissar of the municipal fire brigade. On the day of her entry, Director Meng Moming personally told Wu Ping that she wanted to work safely and happily, and the whole team took special care of her.

But Lu Qingqing doesn't like her colleagues to see her as Lu Anzhi's daughter, but just an ordinary policeman. She worships heroes, and in addition to dreaming of marrying a hero who gallops through the fires like her father in the future, she also dreams that she can become a hero one day. She is not as fiery, strong and resolute as Yu Chili, she has a gentle and delicate personality.

Now, Lu Qingqing only does some clerical work in the office. But after a period of observation, Wu Ping found that Lu Qingqing's views on difficult cases, especially the psychological aspects of pursuing suspects, were different from ordinary people. "You have to let this kid go through it, otherwise he will be blind with a good piece of material." Wu Ping felt that it would be unfair to raise her in a greenhouse just because she was Lu Anzhi's daughter.

Wu Ping quickened his pace, and Vice Captain Gao Ge was waiting for him in the conference room.

"Team Gao, how's it going?" Wu Ping couldn't wait to know the contents of that whistleblower letter.

Gao Ge handed over the report letter to Wu Ping.

Sure enough, the letter clearly explained how Li Chuang went to the blacksmith shop in Guangong Town to build a catapult. "Did he send it himself?" Wu Ping pointed to Yuan Man, the owner of the blacksmith shop, "This name is good, Yuan Man, yes, with your report letter, it will be complete." ”

"I don't know, I didn't see anyone, but the office opened the mailbox in the morning to pick up the letter and found it." Gao Ge replied.

"Since it's a real-name report, there's no need to hide. Well, leave that at that. Immediately send someone to bring Yuan Man back and make a detailed record. No, Gao, you personally take someone over. Without further ado, hurry up. ”

Wu Ping rushed to the county bureau, knocked on the door of the office of the bureau chief, Meng Moming, and handed him Cao Guisheng's suicide note, tape, and Yuan Man's report letter.

"Meng Bureau, I suggest that Li Chuang be wanted immediately."

"Good. At the same time, in the name of the task force, it was reported to the Municipal Bureau and applied for a city-wide investigation. ”

That night, Wu Ping invited guests and set up two tables in the cafeteria of the Criminal Police Brigade.

For half a month, the whole team revolved around the series of cases in Guan Gong Town, getting up early and greedy for darkness, busy and half dead, and now that a breakthrough has finally been made, it's time to celebrate. Gao Ge ran to invite Lin Wencong, but was directly refused. The reason is very simple: Li Chuang has not been arrested yet, and it is not the time to celebrate. And he didn't allow other members of the task force to participate. Obviously, he didn't want to give Wu Pingzi. Why give Wu Pingzi, he Lin Wencong is the deputy director, and he is about to become the director. Vice captain Kong Shangwutuo took a leave of absence due to illness and did not participate, which was expected, he and Lin Wencong were in the same group, and they were completely his followers.

Wu Ping rarely drinks alcohol, but he must drink tonight. After three rounds of drinking, a little drunk, he paced outside the door to smoke.

The night was deep, there was no moonlight, and the street lamp in the courtyard was extraordinarily bright, and it showed the figure of the osmanthus tree swaying in the breeze, as if different people were walking under the lamp. Wu Ping exhaled a puff of smoke, and the faces of Zhou Guoqiang, Wu Changan, and Cao Guisheng flashed in his mind. He looked up, and the faces of these people appeared again in the drifting smoke.

Isn't it going too well? Wu Ping thought.

Smoothness is a good thing, you can bring the murderer to justice, you can return justice to the deceased, and uphold the fairness and justice of the law, isn't that what you have been pursuing. However, Wu Ping always felt that something was wrong, but he couldn't say it. There are still many things that have not been straightened out, such as: Li Chuang's motive for killing Zhou Guoqiang was to take revenge, which is completely consistent with what Geng Score said about Li Chuang's past, but what was his motive for killing Wu Changan? Killing people must always have a purpose, and they will not kill people for no reason. Moreover, Wu Changan died of *** poisoning, although, from the "cyanide" in the tape left by Cao Guisheng...... The word "hua" can be deduced to be *** to prove Wu Changan's cause of death, but Wu Chang'an is *** chronic poisoning, which shows that Li Chuang's killing of Wu Changan was not accidental, but made a careful plan.

Is there a murder-for-life hatred between them? Also, so far, the source of the *** who poisoned Wu Changan has not been found, and there is no strong evidence to prove that Wu Changan bought or made ***, including how he poisoned it, and it has not been figured out.

It can be said that the evidence of Li Chuang's killing of Wu Changan is only based on Cao Guisheng's incomplete recording and Yuan Man's report. Speaking of recording, Wu Ping felt that there were more unreasonable places, when the other party was slightly drunk or got up to go to the bathroom, he secretly pressed the recording button, which is completely possible, but why is the recording basically Cao Guisheng's voice, his words are very complete, and Li Chuang's words are not only pitiful, only a short "yes, no, yes, cyanide" six words, but also intermittent. According to common sense, two people sitting together drinking are about the same distance from the tape recorder, and the clarity of the recorded words should be about the same. In addition, what puzzled Wu Ping was that since Cao Guisheng knew that it was a Hongmen banquet, why did he have to go? He already had the recording in his hand as evidence, and he could have handed it over to the Public Security Bureau. Persuade the other party to turn themselves in and seek leniency? This makes sense, but it's not sufficient. It is not necessary to persuade Li Chuang to turn himself in, he has to go to the place he designated, he can choose the place where Cao Guisheng has an appointment.

What made Wu Ping most unrelieved was Wu Changan's death. The cadres and policemen he sent to Zixian County have returned, and although there is not much well-documented information about the work and life of Wu Changan and other educated youths in the village, as he expected, there are many suspicious points in the case of the suicide of the educated youth. Moreover, they also found a particularly interesting thing: among the seven educated youths that year, in addition to Wu Changan, there was also a person named Cao Guisheng. Wu Ping was thinking, could this Cao Guisheng be Cao Guisheng, the deputy director of the County Education Bureau who was killed by Li Chuang? If so, will there be some kind of connection between the deaths of the two of them?

There were many suspicions, and Wu Ping felt a headache. The most important thing now is to catch Li Chuang. When he is caught, everything is revealed.
