At seven o'clock in the evening, the conference room of the criminal police team of the Tanigawa City Public Security Bureau was brightly lit.

The meeting that lasted from 6 o'clock in the morning to the current one made almost everyone's eyes bloodshot. In particular, the faces of the eight experts who came from the province overnight, including Jin Zuxin and Qin Xiaoming, were even more tired. After all, they have been fighting continuously all night until now.

I'm afraid it will continue forever.

The entire conference room was filled with smoke. The table was littered with depleted cans, boxes of leftover instant noodles and cigarette butts.

Jin Zuxin sat in a chair and smoked cigarette after cigarette. His face was not pretty.

Zhang Lei, who was sitting opposite Jin Zuxin, also had a blue face, and the tea in the gray thermos cup in his hand had been changed again and again.

The two cases over there have not made the suspect have any scruples, and here they actually killed people on the street with guns under the blue sky and daylight. Illegal gun possession, murder on the street, suspected kidnapping, no matter which one is enough for this kid to drink a good pot. Oh, by the way, he even made a provocative phone call in front of all the leaders of the provincial department to embarrass himself.

Zhang Lei sat there gritting his teeth and thinking nonsense.

He has been in the position of head of the Tanigawa City Public Security Bureau for ten years. To say that he didn't want to climb into the province at all would be impossible.

Before Zhang Lei was transferred from the deputy director of the Xinji City Public Security Bureau to the director of the Guchuan City Public Security Bureau, the public security rate of Guchuan City was not said to be at the bottom in the entire Pingjiang Province, even in the whole country of M. In those years, Tanigawa, speeding car robberies, kidnapping and ransom, gangsters, and collusion between officials and businessmen were not uncommon.

If you want to live long, you have to go to Tanigawa. There is water, trees, bays, beaches, and three mountains.

If you want to die quickly, you have to go to Tanigawa as well. Robbery, kidnapping, molestation and murder are commonplace there.

The smooth slip of this joke is precisely the most real Tanigawa in the eyes of outsiders at that time.

As a veteran criminal investigator, Zhang Lei still has a little bit of his own skill in dealing with these underworld forces. The policy of "tightening on the inside and loosening on the outside" adopted by him has achieved certain results in his first year in office. But in the second year, there was a serious problem.

At that time, there was a private group in Tanigawa City that was mainly engaged in the wholesale trade of small commodities, and the owner was called Kim Do-hyung. Although this person is mediocre in appearance and has no skills, his brother-in-law was the deputy secretary of the Political and Legal Committee of Tanigawa City at the time.

Kim Do-hyung relied on the power of his brother-in-law to buy and sell in Tanigawa City, and even monopolized the entire wholesale market of small commodities in Tanigawa at that time. At that time, if anyone dared to compete with him head-on, he would be splashed with feces and urine, or cut off his hands and feet.

The miserable hawkers even resorted to a sit-in in front of the Tanigawa City Public Security Bureau to protest.

Zhang Lei, who had just returned from a meeting in Pingjiang Province, heard about it, so he immediately met with the representatives of the vendors. This time it was not tight, but that night Jin Duheng took the men and horses to the door of the Public Security Bureau with a menacing "killing", and clamored for Zhang Lei to come out and talk to him.

Zhang Lei did not back down. After warnings, dissuasion, and warnings failed, he ordered all police forces to forcibly detain Kim Do-hyung and others on suspicion of endangering public safety and attacking state organs.

Then, in less than an hour, Zhang Lei received three phone calls from the secretary of the deputy secretary of the Tanigawa Municipal Legal Committee in his office.

The content of the call is simple, release the person.

Putting down the phone, Zhang Lei paced back and forth in the office.

His heart may have been shaken for a moment, but he did not compromise in the end.

"We are the people's police of Tanigawa City, and the interests of the people are above all else. And before the law, everyone is equal. ”

It's like the hero-to-hero encounter in every story. The person who told him this sentence at that time made him completely settle down is now forever at the foot of the northern foot of Jishou Mountain in Tanigawa City.

Zhang Lei's eyes were slightly moist, and he came back to his senses and gently wiped the corners of his eyes. The walls of the thermos cup appear a little yellowish under the soaking of tea.

"Zhang Ju, you have no water in this cup, I'll go get you a glass of water first. Quench your thirst and talk to us slowly. ”

That afternoon ten years ago was about the same as it is now. The cicadas in the trees are noisy, and there is not a single wind in the whole sky.

In Zhang Lei's office, two young men with identical khaki backpacks on their backs are standing respectfully in front of him at this moment.

They are high-achieving students who graduated from the Criminal Investigation Department of the National Criminal Police College of M.

Just before graduation, they both received an invitation letter from the Public Security Bureau of Pingjing City, the capital of country M.

Until the two stood in front of him, Zhang Lei couldn't believe that these two young people who came out of Tanigawa City could really give up such a big stage as the Pingjing City Public Security Bureau, and they could resolutely choose to return to Tanigawa after graduation.

"Hello Director Zhang, my name is Su Ruo. Graduated from the National Criminal Police College of M, majoring in criminal investigation. From today, I will be a criminal police officer on the criminal police team of the Tanigawa City Public Security Bureau. Director Zhang Lei, Su Ruo reports to you! ”

"Hello Zhang Ju, my name is Sun Meng. It's all the same as him, except I'm second and he's first. Director Zhang Lei, Sun Meng also reports to you. ”

After the two of them finished speaking, they stood up at the same time and saluted Zhang Lei neatly.

Zhang Lei's face bloomed with joy. All that left his mouth was a mouthful full of "Good, good, good." ”

Sun Meng took Li Suqing and Gu Xiang to push the door in. The smell of smoke in the house choked them with a cough.

"Old Sun! What's going on? Zhang Lei hurriedly stood up and handed Sun Meng a glass of water, Sun Meng took the cup and drank it as soon as he raised his head.

Zhang Lei once asked Su Ruo and Sun Meng about their original intention of returning to the Guchuan City Bureau, and the two of them told him half-jokingly and half-seriously that they were just to return a clear sky to Guchuan City.

Now that there is such a situation in front of the leaders of the provincial department, it is conceivable how much psychological pressure Sun Meng has. Compared with his career, he felt more sorry for Sun Meng in front of him.

"Another policeman died." Sun Meng put down the water glass and slammed the notebook in his hand on the table. The room fell silent for a moment.

"Our police system is absolutely fucking inside! Grass! ”

Sun Meng's rare gaffe caught Zhang Lei off guard.

Fortunately, Sun Meng's adjustment is really strong enough. He took off his hat and grabbed his hair vigorously.

"I'm sorry Director Kim, I'm sorry everyone, I'm out of shape. Okay, while Lao Li and Zhou Kai are going to do an autopsy, I will briefly tell you about today's case. ”

The people in the conference room were all in high spirits, and their faces were full of seriousness.

"At 2:45 p.m. today, a man was shot and killed at close range from the front on Kwun Tong Street in Tieji District, Tanicheon City. Now it is preliminarily identified that the deceased Tong Yu, male, 39 years old, is 1.81 meters tall. Before his death, he was a bailiff at the Tanigawa City People's Court. The cause of death of the deceased was a penetrating wound to the abdominal aorta from left to right, resulting in a penetrating wound that caused massive bleeding in the arteries. The deceased was also killed instantly with a single shot. ”

"Did you find the bullet?" Jin Zuxin extinguished the cigarette butt in his hand, and his eyes were a little cloudy.

"We found a bullet casing with a caliber of 5.56mm from the scene. The forensic doctor judged from the scratch marks on the bullet casing that the gun should have been equipped with a silencer at that time. ”

"Another 5.56mm bullet?" Zhang Lei frowned, the sense of smell of the old criminal investigator made him keenly discover a suspicious point: "Old Sun, you just said that the bullet pierced the abdominal aorta from left to right?" ”

"Yes, Zhang Ju."

"So, the murderer should have used his left hand when he was holding a gun." Zhang Lei kept rubbing the thermos cup in his hand.

"I remember you said in the morning that Shen Ziyi is a left-handed hand, right? If he had done the Fu'an bank case, he would have had a 5.56mm carbine in his hand..."

"No," Sun Meng categorically interrupted Zhang Lei's words, "The suspect in this case definitely didn't use a carbine. ”

Sun Meng gestured with his hand the length of a CQ5.56 carbine and explained: "The barrel length of the CQ5.56 gun is 371 mm. If you add a silencer, the length of this gun should be more than 500 mm. So in a densely populated place like Kwun Tong Street and the street itself is very narrow, the suspect carrying such a large gun on the road must be very eye-catching, and of course, it is not conducive to his escape after the murder. At the same time, when killing the victim, it may cause the victim to be alerted by the police. Since the victim was killed by a single shot, it just shows that he did not anticipate this attack in advance. This also shows that the murderer is definitely carrying a gun that can be extremely light after adding a silencer. ”

"What other gun can shoot 5.56mm bullets besides automatic rifles?" Zhang Lei's expression was full of doubt. Several of the other attendees yawned when they heard this.

"Walter P22." Sun Meng's words made Jin Zuxin not feel shocked.

"The weight of this gun is only 0.48kg. The capacity of the magazine is 10 rounds, plus 1 round in the chamber, for a total of 10+1 rounds. Thanks to the high level of security of the safety system, this gun can be carried with you even when the bullet is loaded. ”

"This gun isn't easy to get in our country." Jin Zuxin's words were agreed by everyone present.

Sun Meng nodded, he opened a bottle of Coke in his hand and continued: "So we can use this gun to lock on to the simulated portrait of the murderer." Judging from the completion of the whole case, the murderer should have a strong psychological quality, so it should be a man. At the same time, he is a left-handed hand, has a wealth of medical knowledge, and must be familiar with the structure of the human body in order to achieve a one-shot kill. In addition, the murderer is quite proficient in the use of the gun in his hand, and the murderer should have a history of professional shooting training. At the same time, the murderer should be familiar with the topographical features of Kwun Tong Street and its surroundings. ”

Sun Meng paused slightly: "So I suggest that the future investigation direction should start from three aspects, one is to investigate the people who had disputes with the deceased and had the motive to kill, the second is whether we have a record of losing firearms in the past ten years, and the third is to give priority to the investigation of locals who meet the above two points." ”

"Why do you need to check and not lose your firearms? Lao Sun, what do you mean when you say that our police system has internal ghosts? Zhang Lei put down the thermos cup in his hand and asked.

"Zhang Ju, do you remember the X medallion?"
