The cold wind blew on the face and felt like a knife shaving, but it couldn't resist people's curiosity.

On the side of the road, the ridges of the fields were crowded with people, and more and more people were stopped. Almost all passers-by stopped. This section of urban and rural roads was not in front of the village or behind the shops, and there was a serious congestion. The traffic police who had just arrived were trying their best to divert traffic.

"Dada"!

The Santana police car kept honking its whistle, and a policeman ran up from the ground to help guide. The onlookers avoided them. The investigation car followed Santana into the crowd and finally saw several police cars from Donggang County Bureau.

"Wei's detachment, the scene is in the south and has been protected."

"Report to the Wei Detachment, Comrade Yuan Zhen, the deputy captain of our brigade, is organizing an investigation, please give me instructions!"

In a few days, it will be New Year's Day. The murder case of two people born and died at the end of the year. The head of the Public Security Bureau and the captain of the Criminal Police looked solemn. Wei Guoqiang raised his hand to return the gift and looked at Lu Chenjun and others who had just got out of the car. While walking into the ground, he asked: "Director Zhang, have the identities of the two deceased been found out?"

"Comrade Jin Yang, report."

"yes."

The captain of the criminal police trotted and followed, pointing to the southeast direction and said, "Some people recognized the victim as the 13th Group of Huaduo. A mother and son, I don't know the name. I have sent police officers to find relatives to recognize the body. The woman was 26 or 27 years old, and the child was five or six years old. She was strangled to death. The money and goods disappeared, and there were signs of a fight at the scene.

The adults are here, and the child's body is in the small ditch in front. There is a bicycle in the ditch, which should be the victim. The adults are not dressed and their pants are stripped off, so they can basically be confirmed to have been raped too much..."

Donggang County is applying to be upgraded to a county-level city, and its economic construction is doing well. This area has obviously been requisitioned, with no walls built but there is a big sign on the side of the road.

There was no work and no one took care of it. A large area was abandoned from east to west. The ground was covered with withered grass, with its head hanging listlessly, trembling in the strong wind, making rustling sounds.

One policeman took a picture, one policeman drew a picture, two policemen searched carefully in the withered weeds, and a policeman in a white coat squatted beside the body for inspection. The county bureau's technical police should have all arrived.

The leaders of the murder detachment who died must come to the scene to guide the investigation as soon as possible. After all, the guidance is guidance, and the investigation work is mainly the responsibility of the county bureau.

There was a scene ahead. Wei Guoqiang stopped and pointed at Lu Chenjun and others and said, "Director Zhang, you know Lu, I won't introduce it. Two corpses and two scenes, the county bureau has insufficient technical strength, you are the commander-in-chief, you arrange and investigate together, and the efficiency is higher."

"I can't ask for it, thank you, Team Wei."

"Thank you, it should be."

"Director Lu, Xiao Li, thank you for your hard work." Zhang Baoli greeted the reinforcements of the municipal bureau and turned around and said, "Comrade Yuan Zhen, come here, the experts of the detachment will support us, you can discuss how to investigate next."

"yes!"

The technical policeman put down his work and came to the meeting. Tian Xuewen looked left and right and didn't know what to do.

He is the "trump card" of case investigation. Wei Guoqiang hurriedly said: "Director Zhang, this must be introduced. Dr. Tian, ​​a master's degree from Union Medical College, and our deputy captain Han Bo, dna appraisal expert invited from BJ. The Municipal Bureau has just purchased a set of DNA inspection equipment worth several million. From now on, our Nangang Public Security Bureau can also use high-tech to solve the case."

The deceased was raped by the murderer, so DNA can definitely be extracted!

Director Zhang Baoli was ecstatic and held Tian Xuewen's hand tightly and said excitedly: "Doctor Tian, ​​welcome, you are really raining in time, it's so good."

"Director Zhang, don't be so polite. I accept the invitation from the Nangang Municipal Public Security Bureau and naturally I have to serve the Nangang Municipal Public Security Bureau."

As he was speaking, two black cars came on the road to the north. The county party secretary and the county political and legal committee secretary arrived. Zhang Baoli greeted him and hurried over to report the situation.

The technicians also held a meeting and the investigation started over. Tian Xuewen and Li Jiaqi first came to the adult's body.

The deceased was in his twenties, with a long head, a straight facial features, and was quite beautiful during his lifetime. The red down jacket was pulled apart, and his upper wool sweater was pushed high, revealing his chest.

The lower body was naked, tights, long pants, underwear and underwear were thrown around. The leather shoes were found, and a policeman was brushing with a brush to see if he could find the murderer's fingerprint. The socks were still on his feet and the heel was worn out. It was imagined that the deceased had struggled before his death.

There is a clear stain on the ground on the lower body of the deceased. If the person dies, he will urinate and some will even defecate.

If there were no outsiders, Li Jiaqi would not have any scruples.

There was an outsider today who was introduced by Team Han and President Li. She didn't want to leave a bad impression on her, but her responsibilities were so she couldn't help but work. She hesitated for a moment, stretched out her fingers to press the dead body spots on the abdomen. After she let go, she faded in a moderate way and did not completely disappear.

Tian Xuewen studied medicine, attended anatomy class, and saw a dead person. She didn't care about her reaction at all. She took out a cotton swab from the investigation box and carefully wiped a small piece of suspected sperm spots on the root of the deceased's thigh. She asked through the mask: "How long will it take to die?"

He is not afraid!

Li Jiaqi was surprised and didn't care about embarrassment. She opened the deceased's outer vagina and asked him to take the possible existence of the murderer's semen, and said in a mosquito-like voice: "In 14 hours, it should be last night."

Tian Xuewen stuffed the first cotton swab into the evidence bag and placed it carefully. He carefully observed the awkward parts of the deceased and the ground. He took out the second cotton swab while continuing to collect it, and said, "The death time is not long, it seems that it has not been cleaned. Why is there so few that it is almost impossible to find."

The small spot just now cannot be confirmed if it is a sperm spot. There is no obvious trace of the vagina outside the dead. The liquid discharged after death has dried up, and only a large piece of stain can be seen faintly, but there is no relatively sticky thing in the stain.

It was a little strange, Li Jiaqi said embarrassedly: "The murderer may have taken measures, or he may not have... been shot."

The first shot must be fired by Brother Han.

Tian Xuewen collected more than a dozen samples in a row, carefully took off the deceased's gloves, stuffed them into a large plastic bag, and stood up and said, "Clean check the lower body to see if you can find the hair."

"OK."

This place was handed over to her, carrying a box to see the child's body, with obvious pinching marks on her neck, and she was only four or five years old, how cruel the murderer should be. Tian Xuewen was filled with indignation and continued to look for biological examination materials with Director Lu, who was inspecting the child's body.

"Wei Detachment, Yuan Da, found a glove, it should be left by the murderer!"

It often only takes a little clue to solve the case. Wei Guoqiang immediately raised the walkie-talkie: "The murderer's dander may be put down quickly and handed over to Dr. Tian."

The detachment leader was on the road, but the policeman with gloves was not far from him.

Director Lu heard it clearly, subconsciously stood up, walked over and took the walkie-talkie from the police: "Wei Detachment Wei, I, Lu Chenjun, gloves can be used as a source of smell. Team Han told us many times that as long as there is a source of smell, the police dog team must be arranged to appear on the scene."

The police dog team appeared on the scene. Is Zhang Wenbin effective for those dogs? What a joke!

Wei Guoqiang was about to reject this proposal. Zhang Zilin, the former head of the Sigang County Public Security Bureau and the current secretary of the Donggang County Political and Legal Affairs Committee, suddenly said: "Wei Detachment, since there is a source of smell, please transfer a few police dogs to help us track it. The golden 24 hours, no one minute can be delayed. As long as there is hope, we will fight for it."

Old friend, and now he is the secretary of the county political and legal committee, he has to give him this face.

Wei Guoqiang put down the walkie-talkie, took out his cell phone, and while dialing the phone number of the technical brigade, he smiled bitterly: "Secretary Zhang, the police dog mainly acts as a deterrent. I hope it will follow it, but you are right. Now you don't care about so many things, you can only treat it as a living horse."

The director of the Public Security Bureau and the captain of the Criminal Police Brigade are organizing the Third Criminal Police Squadron and the police from Chengdong Police Station to visit and inquire. I don’t know when the on-site investigation will be completed.

The investigation work has just begun, and although people are on the scene, they don’t have much information to grasp.

Zhang Zilin looked back at the crowd who were still rushing over from all directions to join in the fun, and pondered: "Han Bo used DNA technology to solve the case when he was in Sigang County Bureau. He is now the deputy captain of the criminal police, responsible for technology, learns to inspect and have equipment. Wei Detachment, if it really doesn't work, call him and ask him to come back and help quickly."

The two died, locals, one of them was only four or five years old.

New Year's Day is coming soon and Spring Festival is coming soon. The impact is so bad that you can imagine how anxious he, the Secretary of the Political and Legal Affairs Committee, is.

Wei Guoqiang issued an order to the technical brigade and pointed to several figures who were surveying in the distance and said, "Secretary Zhang, Dr. Tian is an expert invited by Xiao Han from BJ. He tested the instruments in the morning and tested more than a dozen samples. It was very accurate. He was the same as Xiao Han."

"Xiao Han invited it, that's fine."

"Secretary Zhang, don't worry, this is just beginning. Didn't we test before, we did not solve the case differently?"

"On the way to the scene, our Secretary Yue and County Ma called one after another and asked to solve the case before New Year's Day. Do you think I can't hurry?"

"There are not many outsiders in Donggang, and there are even fewer ones. It should be the locals who committed the crime. Although the 8-day period is a bit tight, there is still a lot of hope to solve the case."

Wei Guoqiang put away his phone and added: "A quarter of the more than 30 murders born in the city this year were solved within three days and two quarters were solved within one week. Judging from the current situation, this case is very likely to be a bit difficult to solve, but there are only so many permanent residents. If you organize police forces to investigate, the problem should not be very big."

"I hope."

The investigation is still continuing, but Tian Xuewen will not stay here for a long time.

The soldiers are the gods, Wei Guoqiang didn't want to delay for a minute, so he arranged for someone to drive a Santana police car to take him back to inspect the first batch of biological materials, hoping to find out whether the murderer had left DNA evidence as soon as possible.

On the way back to the city bureau, Tian Xuewen called Han Bo's cell phone and rubbed his stomach to complain: "Brother Han, the police are really not a job. I did the experiment all morning and was taken to investigate the scene as soon as I finished it. I haven't eaten lunch yet!"

"Sorry, you caught up with me."

Han Bo put down the newly sorted documents and stood up and said, "This is also a training for you. You are a future oncology expert. It will take more than ten hours to encounter a major operation."

"I don't know when I go to the operating table. I won't talk about it anymore. There is a shop in front of me. I can buy some food and keep my stomach on the road. When I go to your public security bureau, I will continue to do the experiment."

"Thanks for your hard work."

"It's not just me, but forensic doctor Li didn't eat it. He is still on-site investigation now."
