Serious Crime Unit 1

Chapter 1285 Never Compromise (5)
"Yingying, you lead the surveillance team to collect all the surveillance videos near Butterfly Valley Resort to see who is suspected. Xiaorou, you go and keep an eye on the netizens on the city government website to see who scolds the most, and then find out who Their IP addresses, Lao Wu and Xiao Ke will check the ballistics, and Zhou Ting and I will investigate who has the motive for killing." Jiang Yiming arranged the task.

Wu Jiang and Xiao Ke brought ballistic detectors to the place where You Shiliu fell off the cliff to prepare for detection. However, because the wheels are rolling and the speed of the vehicle is not known, it is impossible to accurately detect the ballistics. They can only The range of detecting the approximate direction the bullet came from is relatively large.In the past, they detected ballistics because the bullet was shot into a fixed human body, so it was easier to detect.

Fortunately, there are still traces of tires left on the road when braking. Under normal circumstances, after a tire explodes, people will react within a second and step on the brakes.They started the detection two meters back from the starting point of the brake mark, and continued to detect it 5 meters away. Within these 3 meters, they detected a total of 6 times, and then used a computer to comprehensively analyze and came up with a point, this The point is a small hill 100 to 120 meters away from the cliff.

Of course there is an error, but the error is not too big.The two of them put away their ballistic detectors, carried the survey box, and climbed toward the hilltop called Tiger Hill.Huqiu Mountain overlooks the winding mountain road of Butterfly Valley Resort, with a drop of about 50 meters. The mountain is covered with 1-meter-high pine trees, which are just three years old.

They climbed up the overgrown hillside and reached the top of the mountain 20 minutes later.The view here is wide, there are no trees blocking it, and there are several rocks tens of centimeters high around it, making it the most ideal sniper spot.

They put on shoe covers and carefully searched for shoe prints on the ground. It had only been 55 hours since the incident, and it had not rained. Most of the top of the mountain was dirt, which was a good attachment for shoe prints. As long as the murderer It was here to ambush You Shiliu's tire, so it would definitely leave shoe prints. Even if he was wearing shoe covers, he could determine the murderer's size and weight.

As expected, they found a line of footprints heading towards a rock about 1 meter high. There were no shoe marks on the footprints. It was obvious that the suspect came here wearing shoe covers to ambush You Shiliu. Otherwise, what was left behind would not be footprints, but Shoe prints, there is a fundamental difference between the two.

Wu Jiang took out a Nikon SLR camera to take pictures of the footprints and took 20 photos.The footprints were left by size 43 sneakers. Judging from the depth of the dirt, the murderer was about 178 centimeters tall, weighed about 70 kilograms, and had a very standard build.

Judging from the gait analysis, the murderer should have been a soldier or a soldier. Of course, it is unlikely to be a Chinese soldier, and most likely a foreign soldier.If a Chinese soldier stole a sniper rifle and absconded, I believe that the entire Chinese police force would not have a good night's sleep, including the military leaders.

Xiao Ke took out the soft plaster from the survey box, squeezed the plaster out, and poured it on the footprints. After the plaster dried, he could get the inverted footprints.This is also strong evidence. Even if the murderer wears shoe covers, the footprint inversion can be used to analyze the murderer's gait with a gait meter, and the error will not exceed 10%.

Wu Jiang found that the footprints were concentrated next to the 1-meter-high rock. There were 8 footprints in total, all left by the same person. This meant that the murderer had been waiting here for a long time. He kept changing postures or standing still to leave such footprints. Multiple footprints.

Fortunately, it was cloudy today and multi-band light sources could be used. Wu Jiang took out the multi-band light source from the survey box and illuminated the rocks. The result was an unexpected surprise: it turned out that sweat stains were found on the rocks!Needless to say, the sweat was left by the murderer, because the temperature on the night of September 9th was as high as 12 degrees Celsius, and the murderer was mentally stressed, so sweating is very normal.

Wu Jiang took out the cotton swab and the solution, dropped the solution on the sweat stain to dilute the sweat stain, then dipped the cotton swab in the sweat to extract the sweat, then put the cotton swab into the test tube and closed the lid.Wu Jiang thought: If DNA is made from sweat and compared in a database, the murderer might be caught and brought to justice soon!
Wu Jiang continued to search for the bullet casing next to the rock. After searching for a long time, he could not find it. The bullet casing must have been picked up by the murderer. Generally, the bullet casing has a number. From the number, it can be seen which military industrial company it came from. Therefore, the murderer can only Take the shell casings away to avoid detection by the police.

After the plaster was dry, Xiao Ke collected the two footprint molds, put them into the evidence bag, and expanded the search area with Wu Jiang. As a result, they searched until 12 noon and found nothing new. So, they went down the mountain, and Xiao Ke Ke drove back to the team for lunch.

Wu Jiang handed the sweat swab to Luo Jin and asked him to test the DNA, then took the warhead to detect the bullet marks, and then took the results to the ballistics database to compare, but there was no match. This means that the sniper rifle did not come from the military or criminals. Sinful sniper rifle.In fact, China's bullet mark and ballistics database has very little data, and it is very slim to find the murderer.

Before getting off work in the evening, after Jiang Yiming returned to the team, he called everyone for a short meeting and asked everyone to summarize the investigation situation.Wu Jiang told everyone about the suspect's sweat and footprints collected.Wen Xiaorou said that she collected 50 people who criticized You Shiliu the most harshly from various government affairs forums, and found out their IP addresses, which required in-depth investigation.

Lu Yingying's surveillance team has also collected 2500 hours of surveillance video. They are reviewing it. However, since there is no specific suspect, it is difficult to investigate. Now that they know the suspect's height and weight data, they will go to this target. effort.

Luo Jin also made the suspect's sweat DNA and took it to the database for comparison, but there was no matching DNA and he could not identify the suspect.He also used the Y-STR test method to try to find the suspect's relatives, but there was no result.

Jiang Yiming and Zhou Ting went to ask Fan Mufeng, You Shiliu's secretary.She said that You Shiliu listened to the teacher's lecture at the Municipal Party School on the morning of September 9, went to the Provincial Youth League School in the afternoon to exchange work ideas and experiences with outstanding Youth League cadres from Xiyan City, and took everyone to Butterfly Valley Resort for dinner in the evening. After dinner, she drank tea with the secretary of the Youth League Committee of Xiyan City and two deputy secretaries in a tea bar, and did not drive home until 12 o'clock.Fan Mufeng said that You Shiliu rarely does the work of the Municipal Youth League Committee recently, and the daily work of the Municipal Youth League Committee is done by the first deputy secretary. She was transferred by the mayor to be the deputy director of the Epidemic Prevention Headquarters.She is mainly responsible for epidemic prevention work. This job is tiring and will encounter abuse from the masses. However, she always does not care and insists on implementing the work requirements of the municipal government.I don’t know who she offended?

"Captain Jiang, I found someone on multiple online forums scolding You Shiliu for changing the health codes of many citizens for no reason. They originally had good green codes, but they didn't go anywhere. I didn't expect that the next day. The health code became a red code. Therefore, many netizens abused You Shiliu because she is the deputy commander-in-chief of epidemic prevention." Wen Xiaorou said.

"Do you mean to say that the murderer may be among these citizens who have been assigned red codes?" Jiang Yiming asked.

"It is possible, but generally citizens who have been assigned a red code do not have the ability to snipe Yu Shiliu's tires, and it is unlikely that they will have murderous intentions and take action because of being assigned a red code. After all, killing requires a life." Wen Xiaorou said.

"That's not necessarily the case. If a capable person is assigned a red code and his family changes or his business fails, he may have murderous intentions." Xiao Ke replied to Wen Xiaorou.

"Family accident? What do you mean?"

"For example, if a filial son wants to go home for treatment or death because his parents are critically ill, but he is stuck in one place and cannot move because he is given a red code, then he may hire a murderer or do it himself."

"Yes, I have heard that You Shiliu is the deputy commander-in-chief of epidemic prevention, and Yan Tai is the commander-in-chief. They have the power to assign a red code to any citizen. This matter was reported by the masses, but they were only verbally criticized by the municipal party committee. , and no substantial punishment was imposed, causing many citizens to complain." Wu Jiang said.

"Why are You Shiliu and Yan Tai doing this? Isn't this just doing whatever they want?" Jiang Yiming didn't understand.

"There must be some ulterior motive, otherwise who would want to offend the general public?"

"Xiaorou, have you seen in the comment area how many citizens have been assigned red codes?" Jiang Yiming asked.

"No, I only saw 18 citizens in the comment area saying that they were given a red code for no reason, but the exact number is unknown. Captain Jiang, I suggest you ask Secretary Yan Tai if You Shiliu is really because of If he was killed in the red code incident, Secretary Yan Tai’s life may also be in danger,” Wu Jiang said.

"Okay, I'll discuss it with Bureau Fang and go visit Secretary Yan together...Old Wu, did you find the source of the gun when you were detecting the bullet marks?" Jiang Yiming felt that Wu Jiang's words made sense.

"No, the bullets are not fired by regular sniper rifles. They should be imitation Type 85 sniper rifles. It is very difficult to find the source of the gun. We still have to look for clues from who has the motive for killing. The murderer is either a rich man or a gangster. For those who have served as armed police officers or special police officers, the scope has narrowed a lot.”

"If it is an imitation gun, or a gun from abroad, it is really difficult to find out where the gun came from. Why didn't the murderer hit Yu Shiliu with one shot, but hit her tire? And there are only 120 kilometers between the sniper point and the bullet impact point. [-] meters." Jiang Yiming was a little confused.

"I think the reason why the sniper targeted Yu Shiliu's tire at such a close range may be because he did not have confidence in himself. Of course, it may also be that Huqiu Mountain is the best sniper spot." Xiao Ke replied.
