Mystery Tracker 3

"stop!"

When Shen Yan and the others saw the trash thrower running away, they immediately chased after him, but the boy ran very fast and turned across the intersection in a blink of an eye.At the same time, there was a shout from the intersection: "The police are here, run!" The three ran across the intersection, only to see a group of peddlers running away pushing their cars.Seeing this situation, the three of them couldn't laugh or cry. It seems that these small traders regard them as people who are catching illegal business.

Seeing the frenzy, the three of them knew that there was no point in chasing, and at this time Cheng Haiyang also caught up from behind, panting and waved at Shen Yan: "Boss, you don't have to chase anymore!" , I have checked, the bag contains bamboo sticks, peanut skins, etc., it should be from a skewer stall, not the person we are looking for.” After speaking, he noticed that those who pushed the cart ran away I couldn't help laughing, "No wonder that kid ran away as soon as he saw us just now. He is treating us like urban management!"

"There was no surveillance on that road just now, but there is only a corner away from the garbage spot. These small vendors may have seen the person who threw the garbage." Shen Yan said to a police officer of the Chengnan Branch: "Little Liu, contact the police at the police station in this area tomorrow, and ask them to find a way to find these small traders and see if any of them have seen any suspicious people."

"it is good."

4 month 8 day.

At six o'clock in the morning, the city bureau's on-duty dormitory was quiet.

Shen Yan glanced at Shen Hao who was sleeping peacefully on the opposite bed, put on his coat, and walked out of the room lightly.As soon as the door was closed, Cheng Jinsong came out from another room diagonally across.

Seeing each other, the two smiled at the same time—the old man has been in sync for many years, and the biological clock has indeed been in sync.

Last night, whether it was the crime team or the forensic team, the vast majority of people slept in the bureau. The Public Security Bureau of City S originally had a police dormitory for single colleagues who had just started working and had no housing, or for police officers who were investigating cases too late to rest temporarily.The police station had refurbished the dormitory building the year before last, and now the dormitory room is shared by two people. Except that there is no separate shower room, it is almost the same as a standard room in a hotel.At that time, Wang Ju's original words were: Everyone has worked so hard, even if it is a temporary nest, you should live more comfortably.Last night, no matter whether it was the serious crime team or the forensic team, everyone was busy until after 12 o'clock in the morning. Except for a few families, old and young, who insisted on going home, everyone else chose to spend the night in the dormitory. — After all, they had to continue their work this morning.

"How is it? Is Shen Hao still asleep?" Cheng Jinsong asked softly.

"Well," Shen Yan nodded, "He was busy until late yesterday, I lay down, and he was still fiddling with the computer."

"Surveillance is a big problem. Besides, we haven't determined the specific place to dump the body, so it must be enough for him. I applied to Xiao Bureau yesterday, and I seconded a few people from the branch to help him do this together." Cheng Jinsong said After that, he noticed the smiling expression on the corner of Shen Yan's mouth, and immediately understood, "Why, I haven't been with your brother for a long time, remember the old days?"

Shen Yan nodded.When he and his younger brother reconciled a few years ago, they lived together in the police dormitory.Before that, Shen Yan and Shen Hao had no contact for eight years due to some misunderstandings, and finally reconciled with Cheng Jinsong's help.When Shen Yan thinks about it till now, he still misses the time that only belonged to the two brothers.

"You don't know, the way he was sleepy and said 'good night brother' to me last night is exactly the same as when he was a child." Shen Yan couldn't control the smile on the corner of his mouth.

"Wake up, your brother is almost 30." Cheng Jinsong teased him with a smile, "I really miss him, so I'll stay with him for a few nights in two days."

Shen Yan shook his head: "Let's talk about it, he has now converted the guest room into a study room, and there are piles of computer hosts and the like in it, and there is no place to sleep at all. It is not convenient for me to share a bed with him in the master bedroom. "

"Your brother is addicted to the ocean of technology and can't extricate himself. By the way, he is not young, should he have a girlfriend?"

"I've told him a few times, and he always says he's not in a hurry. Forget it, let it be."

"That's right, you only dated in your 30s," Cheng Jinsong smiled and winked, "It's never too late for a good meal."

Shen Yan rolled his eyes at him: "It's been so many years, why can't your thick-skinned problem be cured?"

Just as Cheng Jinsong was about to talk to Shen Yan, someone suddenly appeared in the stairwell, and the two immediately restrained their expressions and pretended to be talking normally: "How was your investigation yesterday?"

"Oh, a total of 14 locations, two of which have been confirmed to be covered by surveillance and can be fully traced to whoever was present in the past 24 hours. Of the remaining 12 locations, four locations have university surveillance cameras, and today I need to get relevant videos from the university. The remaining 4 are more troublesome. There are neither municipal traffic surveillance videos nor private surveillance videos such as campuses or other shops near them. They can only be checked by other methods. It is." Shen Yan said.

Cheng Jinsong nodded: "Shen Hao also told me about this matter yesterday. His idea is that he can first divide suspicious locations into closed-loop areas through the nearby municipal or other surveillance videos, and then filter and filter them within 24 hours. All vehicles and personnel entering and leaving this area. Although the amount of operation is relatively large, if it is ideal, it can be guaranteed that the suspect will not be missed. If it can be compared with the suspect locked from the victim, it should be Helps pinpoint the real culprit."

Shen Yan nodded, and asked again: "How about the physical evidence? Did you find any important clues?"

Cheng Jinsong shook his head: "The inside of the plastic bag has no fingerprints at all. The outside is too polluted to extract clear and complete fingerprints. Moreover, the sundries in the two plastic bags, except for some of the excrement overflowing from the deceased's organs, are various kind of garbage—I suspect that these garbage are mixed into the garbage bags during the process of transshipment and dumping.”

The two communicated with each other sentence by sentence, completely forgetting that their original intention just now was to deceive others.But this is actually the normal life of the two of them. After all, for a criminal policeman, almost all the time outside of sleeping is work. "No distinction between public and private" is probably an important reason why the two have been in love for four years and can still hide their relationship in the police station.

Of course, when it comes to "desperate", no one in the criminal investigation team is too far behind.When Cheng and Chen walked into the office of the forensic team after breakfast, there were already many people in the room.Jiang Xin was standing in front of Cui Mingyou's computer and discussing something with him. When she heard footsteps, she turned her head and said to Cheng and Chen, "Cheng team, Shen team, some bad news: the death of the deceased The DNA has been extracted, but there is no match after comparison with the DNA library."

"What about the missing persons?" Shen Yan asked.

"The missing persons in this city have been checked," Cui Mingyou answered this time. "Among them, there are 20 females aged 25 to 17. Two of them have their DNA in the system, but the deceased compared In addition, I also checked the missing women who met the age requirements in other brother cities in the province, a total of [-] people, and [-] of them with DNA records were also excluded."

"Call the relatives of the remaining missing persons and ask them to come to the bureau as soon as possible to provide the missing person's DNA." Shen Yan said, "In addition, an announcement will be issued throughout the city, and if there are missing women who meet the age requirements, their relatives and friends should report as soon as possible. "

"I've finished calling people in this city just now, and I'll call people in other cities when they get to work."

Shen Yan nodded, then turned to Jiang Xin: "Any other findings from the autopsy?"

"Toxicological tests have confirmed that the deceased did not die from poisoning. In addition, no lethal lesions were found in the major organs of the deceased, indicating that she did not die from a disease. Since the head of the deceased has not been found so far, the real cause of her death cannot be confirmed yet. , but the most likely ones are: sharp injury, severe injury or mechanical suffocation.” Jiang Xin paused at this point, and then added, “However, it is certain that the deceased was dismembered after death. Moreover, no obvious congestion can be seen from her skin fragments, so it is estimated that she probably did not suffer too much crime during her lifetime."

Hearing this sentence, several people were slightly silent.Even if the deceased could not feel the pain after death, this did not comfort the detectives who were looking for the real murderer of her.

"Are there any other clues that can help determine the identity?" After a while, Shen Yan continued to ask.

"The biggest problem now is that the deceased's bones, head and limbs have not been found. These are actually the parts that can best identify the deceased." Jiang Xin said.Seeing that Shen Yan frowned, she added: "However, we can also have some general references. We know that the bone weight of an adult accounts for about 20% of the body weight, which means that the weight of the internal organs, skin and muscles of the human body accounts for about 80% of the body weight. About 23% of the total weight. I have weighed the total weight of all the corpses found so far, only about 35 kg. Even if the muscle dehydration and the missing brain, limbs, etc. are added, the total will not exceed 45 kg. Calculated based on this data , the weight of the deceased was less than 90 kilograms, that is, [-] catties - with such a weight, it is estimated that the deceased would not be too tall, and his body should be relatively thin."

Shen Yan nodded: "This is very important, it should help us eliminate many people."

The two were talking when suddenly Cheng Jinsong's cell phone rang.

"Hello, Bureau Xiao." Cheng Jinsong answered the phone, "Oh is that right? Okay, let them come up to the seventh floor."

After hanging up the phone, he said to Shen Yan: "The people from the sub-bureau are here to help process the image information."

After a while, five police officers in police uniforms came to the office of the forensic team.These five people were of different ages, three of them were acquaintances Cheng Chen had met before, and the other two were newcomers who had just been assigned to the branch office last year.Everyone first informed each other of their names, and then Shen Yan gave them a brief introduction to the case.When they heard that this case was closely related to the murder and dismemberment case 20 years ago, everyone's expressions became serious instantly.

"Because the body was found in a garbage dump, we cannot determine the specific place where the body was dumped. Moreover, all the physical evidence has been greatly polluted, so the clues that forensic evidence and autopsy can provide are very limited. Therefore, for now , Surveillance images are the direction where we are most likely to make a breakthrough." Cheng Jinsong said, "However, the scope of search is very large, and you will find out after a while that most of the roads where garbage stations are located are not monitored, so we need Divide the area for screening from the surrounding video-this task will be very hard, everyone must be mentally prepared."

Several people nodded seriously.

"Okay, I'll take everyone to the audio-visual analysis room." Cui Mingyou took the job automatically.

"I analyzed and monitored with them and Shen Hao this morning." Cheng Jinsong said to Shen Yan, "What are you doing today?"

"The rest of the body hasn't been found yet. Li Yuan will look for it this morning in conjunction with the branch office and the police station. I will go to several universities over there and ask them for surveillance video."

"Okay." Cheng Jinsong nodded, thought for a while and added, "By the way, please ask if there are any college students who have disappeared from their school recently."

Shen Yan paused: "Do you suspect that the deceased is a college student of these universities?"

"The deceased was a student of S University." Cheng Jinsong said, "Although we can't confirm the relationship between the two cases, it is always safer to check. Moreover, the age group of 20-25 is the students of college students." age, and the management of students in universities is relatively loose, so some students who are missing have not been reported yet.”

Shen Yan felt that Cheng Jinsong's analysis made sense, so he nodded: "OK."

There are four universities in Seongnam University City, namely S University, S City Medical University, S Sports University and S City Institute of Science and Technology.Yesterday's garbage truck passed the living areas of three of the universities.The first task of the serious crime team today is to visit these universities and copy their relevant surveillance videos.They first went to the South Campus of S University.When he heard that the head of the criminal investigation team of the Municipal Public Security Bureau came to visit in person, the vice president of S University looked as if he was facing an enemy.

"There was a recent case where the victim was a young woman between 20 and 25 years old." Shen Yan replied in the same way, without disclosing key information. "By the way, is there any female college student who lost contact in your school recently?"

"No." The answer was Director Chang Jiao of the Security Department. "Our school is very strict about the management of students. It adopts the dual responsibility system of dormitory teachers and counselors. If any student does not return at night, they must report Two teachers asked for leave."

"But isn't the Qingming holiday just over? If a student asks for leave but doesn't come back in time, maybe the teacher hasn't noticed too much." Shen Yan insisted, "You can check with the teachers of each department. .”

What Shen Yan said was quite reasonable, so the vice principal said to the chief security officer: "Director Jiao, then you should contact the counselors and teachers of each department, and ask them to report the attendance and absence statistics of the last few days .In addition, if there are students who have asked for leave and have not come back, ask the teachers to call to confirm and see if there is any student who cannot be contacted."

"it is good."

Chief Jiao got the order and immediately went out to work.

So Shen Yan and the others checked the surveillance while waiting for Director Jiao's reply. S University's monitoring is mainly concentrated on the campus and various entrances and exits, but the cameras near the backyard wall are extremely limited.Several people checked all possible shots outside the back wall, but found nothing.When the video search was coming to an end, there was a knock on the door suddenly, and Director Jiao walked in leading a female teacher.

"Captain Shen, we have just completed the statistics of each department..." Director Jiao said, but his face was much more anxious than before he left the house, "Well, we found out that there is a girl in the art department who may have lost contact. ..."
