The "801" case handling cycle is only one week, and it will not exceed half a month if you count the initial investigation and re-examination.

The cycle is set by itself, and the department has never mentioned this requirement, let alone limit "801" to crack a certain case within the specified time limit. Vice Governor Peng Xiangyuan proposed on the phone to "strive to solve the case within a week", which is unprecedented, and one can imagine how much attention he attaches to this case and how anxious he is.

It's not easy to meet a good boss, even if it's nominal.

After the relationship was transferred from the Department of Justice to the Public Security Department, he almost responded to requests. As a vice governor with a lot of real power and a member of the Public Security Department, in this official-oriented environment, he can put his posture so low and discuss everything. Some time ago, because of a joke, I won a deputy inspector under pressure from all sides.

Although it really doesn't matter whether there is such a non-leadership position at the deputy department level, Han Jun is still grateful.

He likes Jiang Province, likes the provincial leaders including Peng Xiangyuan, likes this "side job" in the Public Security Department, is very satisfied with the current state of life, and is convinced that only in Jiang Province can he mix like a fish in water now, and he will definitely not be so comfortable in other places, let alone be able to get respect and respect from top to bottom.

Serial murderers are too crazy and too dangerous!

I don't know when it started, Director Han Da has regarded Jiang Province as his own territory, and he is unscrupulous on his own territory, repeatedly seeking money and killing people, which is unbearable.

Director Han was furious, and the Operations Section had a task.

In order not to waste even a minute, the Operations Department urgently assembled, and Hu Zhengcai and two heavily armed special police officers drove the Mitsubishi Pajero to open the way for Volvo. The other three SWAT officers drove behind the Ford "nanny car" painted in a police car. Lights were lit, sirens were sounded, and the city was crossed under the guidance of the Jiangcheng traffic police. Get on the highway at the fastest speed and go straight to Dongjing.

The Investigation Bureau is most familiar with Haidong's case of the unknown female corpse three years ago. Liu Huafeng was temporarily transferred to the inventory headquarters, holding a laptop to study the case again.

Tan Yanbing and Li Sijin were in charge of the "case" that occurred in the first half of last year, and seized the time to study the materials on the murder of Li Feiya, an accountant of some companies in Dongjing Zhuangzhuang Animal Feed; Sun Dayong and Qin Chaolong were responsible for the "case" that was not reported by the Jingxi Branch of the Beijing Municipal Bureau; Li Zhongchen and another Dongjing police officer from the Second Section were responsible for the attack on Gan Xiaolong, which occurred more than half a month ago.

Xia Moqing was responsible for coordination, research and judgment, and Qi Zhaoyou continued to analyze the forensic identification reports and on-site investigation reports of three homicides and one injury case.

The conference room is busy, and the lounge is not idle.

Han Jun has answered three phone calls since he got in the car, and as soon as he finished talking with Deputy Director Chen, Zhu Junfeng called in, and asked him for help as a member of the Standing Committee of the Dongjing Municipal Party Committee and executive vice mayor.

After fooling the layman who knew how to make a mess in a few words, he finally waited for the call from the insider.

"Director Han, you have helped a lot this time. The information discovered by Comrade Qi Zhaoyou is very valuable. If a qiē is verified, if your speculation is correct, then the scope of investigation can be greatly narrowed, focusing on Haidong and Haidong's surrounding personnel in Tianjing, or local suspicious people who have been to Haidong and Haidong's surroundings a year ago.

Zhongwang has already led the forensic technical experts to set off, and from now on, our Criminal Investigation Bureau will be divided into two ways. I supervised in Dongjing, and he went to Haidong to supervise the war. The female victim's body was not cremated, and they immediately conducted an autopsy after arriving, and immediately organized the public security bureau of Haidong and several surrounding counties and cities to investigate after the autopsy was confirmed. Emphasis is placed on ex-convicts who have absconded in fear of crime and missing persons who have not returned home in the past two years......"

Homicide investigation often only needs an opportunity or a valuable clue, one ring after another, it is a criminal investigation drama, that is for the needs of the plot, in fact, 99% of homicide cases will be found to be very simple after they are solved.

There is no problem with the direction of investigation determined by the special case team of Wei Leshan and the Dongjing City Bureau on the basis of the new situation. The "801" organization will do the same.

Han Jun breathed a sigh of relief, leaned on the door of the lounge and asked, "What about the rest?" ”

Wei Leshan cleared his throat and introduced loudly: "Last year's case where the body was not found. Although the Jingxi Branch did not report anything, the preliminary work was basically done. Some physical evidence was collected. All video surveillance around the site was extracted. We unanimously believe that no matter how cunning the murderer is, he will not be able to evade all surveillance, and we are dispatching graphic investigation experts from the Criminal Technology Center and several municipal bureaus such as Jiangcheng and Dongzhou. A careful analysis of the videos of three homicides and a robbery and homicide.

At the same time, additional police forces were dispatched to railway stations, bus stations, checkpoints and public security checkpoints to check every person who left the city. Now I have a lot of clues, such as approximate height and weight, such as the possibility that he is from Haidong or has been to Haidong a year ago. In addition, the police force is organized to focus on the investigation of all construction sites and decoration companies in the city, Haidong is the hometown of construction, and there are many Haidong personnel engaged in construction and decoration, which must be carefully screened. ”

Han Jun groaned: "Lao Qi speculated that the murder weapon should be the kind of small hammer commonly used, and he did the test last year, and even the model and style were determined. Construction workers and decoration carpenters are used more, and they should indeed be checked. ”

"That's what we think too, that's the basic situation, when will you arrive, and we'll meet again when we get there."

"After seeing the three scenes and the injured, it will be about 10 o'clock in the evening, and then the case analysis meeting will be held, and the meeting is estimated to be after 11 o'clock. Wei Bureau, I don't want to make such trouble, you are busy with yours, we will check ours, and if there is any news, please ventilate in time. ”

The case is urgent, and it must be solved quickly, and you can't put all your eggs in one basket.

Wei Leshan nodded slightly, held his mobile phone and said, "It's okay if you don't meet, the task force won't interfere with you, and you won't interfere with you." I'm in the middle of the media, and I'm going to give you a message. ”

Han Jun noticed from what he had just said that Yang Zhongwang led several "criminal technology experts" to Haidong, instead of the general "criminal investigation experts" before.

There is a reason for this, since "801" became famous, no one in the public security system of Jiang Province has claimed to be a criminal investigation expert, and these four words can not even be found in the text and propaganda. There are only experts in trace examination, forensic pathology, DNA testing, trace physical evidence, document examination, intelligence information, pre-examination, video analysis, ballistic examination and electronic physical evidence examination hired by the ministry or the provincial department.

Forensic technology has been taken seriously, and some leaders no longer hold the title of criminal investigation expert at every turn, which is a kind of progress. Thinking of this, Director Han smiled with satisfaction, opened the door and walked into the conference room.

"Director, look at the map I just marked."

Xia Moqing is definitely a competent intelligence research and judgment expert, and she can express what she wants to express with a map, Han Jun stared at the LCD screen for a while, and then turned around and said: "The murderer has a large range of activities, and the targets are both men and women, at least there is no rule in the selection of targets." ”

"The more this happens, the more dangerous it is, and if you don't solve the case, no one knows where the next murder will happen, and whether the next victim will be a man or a woman."

It's really dangerous.

Han Jun thought for a while, and suddenly asked, "Tan Yanbing, how much money was robbed of that accountant last year?" ”

"Forty thousand cash withdrawals from the bank. In addition, it is said that the victim's family said that Li Feiya had played mahjong the night before he was killed, and he probably had more than 2,000 cash on him, including the stolen mobile phone and gold ring, about 50,000 yuan. ”

"The second murder in which a complete body was not found occurred more than seven months later, which means that he has almost spent his money, or that he wants to make another sum of money for the New Year."

Li Zhongchen raised his hand and said, "Director, if this is the case, then the murderer is likely to continue to commit crimes." Because he didn't get much money from Gan Xiaolong, the family said that the injured didn't have the habit of bringing much cash, and the cash on them would not exceed 1,000. ”

"Haidong didn't find the same footprints in that case, and after a few years, he couldn't have worn the same pair of shoes, and it was impossible to determine that the same person had done it based on the modus operandi and wounds. Director Xia, Lao Qi, I'm worried that our kindness will not help, and the information just provided will mislead the task force to investigate. ”

"Director, it's better to have clues than no clues now, not to mention the Dongjing City Bureau Task Force, even we can't take care of ourselves so much."

"That's right."

Han Jun sighed lightly, clicked on the laptop, investigated the footprint photos, and said: "Everyone, I have an idea about this shoe print, I feel that the murderer seems to have specially prepared a pair of shoes to wear when committing the crime, otherwise the sole lines would not be so clear, like a pair of shoes just bought." ”

Xia Moqing racked his brains and thought for a while, then suddenly smiled: "Director, there is a saying that being smart is mistaken by being smart, this may be a mistake made by the murderer himself." He may have learned some anti-investigation methods through film and television, but at the same time, he was deceived by those screenwriters and directors, who changed into clothes, gloves, and shoes that they rarely wore or even did not wear when committing crimes, but instead left us clues about the joint investigation. ”

The police are not afraid to encounter well-prepared cases, because the longer the preparation time and process, the more traces and flaws will be left, and the later the investigation will be traceable. I'm afraid of that kind of sudden crime that starts on the impromptu intention, such as two strangers on the road who unintentionally rub each other, wield a knife and wave a knife, one dies and the other escapes, there is no way to start.

There are indeed a lot of clues left by the murderer, and the key is how to lock him down.

"With such a large range of activities, a homicide and a robbery and wounding occurred during the day, it should not be a construction worker. After all, the construction site has management, and the construction party has a construction period. As far as I know, the decoration carpenters are more mobile, and they are often seen squatting on the side of the road and waiting for a sign in Jiangcheng. There are means of transportation and tools for committing crimes, but we can think that the task force can also think of it, maybe they are already investigating. ”

Han Jun paused and shook his head again: "Although it meets these characteristics, I feel that it is also unlikely that the murderer is a decoration carpenter." First, there is craftsmanship, the wage is higher than that of construction workers, and it is not so hard, it is not difficult to earn forty or fifty thousand yuan a year, and it is not necessary to take risks. In addition, if Haidong did it, if he had a criminal record, he would definitely hide incognito and hide very secretly, and he would not dare to contact his fellow countrymen lightly.
