Qingquan County, under the jurisdiction of Bz City, is located at the junction of Bz City and Tianzhou City. It has many mountains, hills and few plains.
Qingquan County is small in area, with only 70,000 to 80,000 permanent residents in the urban area. Including the rural population, the county has less than 300,000 people.
But Qingquan County's economy is not lagging behind. Because of its mountainous terrain, Qingquan County has unique microclimate characteristics that are different from other places.
It is humid and rainy all year round, with lush plants and a wide variety of animals in the mountain. It is a well-known tourist summer resort.
Not only that, Qingquan County has been rich in herbal medicines since ancient times, and all the towns and villages in the county are famous herbal medicine planting and distribution centers.
There are many traders coming and going, and there are also many local people collecting medicine in the mountains. A group in Yumin Village, Changchun Town, Qingquan County. Outside the courtyard of a farmhouse in the west end of the village, police cars with their lights flashing were parked.
Around the police car, more than fifty local farmers were watching. In the yard is a three-room brick house, each with two east and west wing rooms. There is a barn on the east side and a cattle pen on the west side.
In the room, Lu Chuan was conducting on-site inspection. There were two corpses on the kang, a middle-aged female corpse lying horizontally and a middle-aged male corpse standing vertically.
The corpse was fully clothed, and the neck of the male corpse was cut off with a sharp weapon, leaving only a trace of flesh and skin attached. The spray of blood was more than two meters high, and there was a brown stain on the ceiling.
The head of the female corpse was covered with black blood, lying on the edge of the fire bed. The ground was covered in dried blood, as was the wall.
Li Donglin stood outside with a pale face, looking through the window on the stove at Lu Chuan who was busy inside.
This is the third murder case discovered by the task force recently. In December, after the murder case of Song Kun was solved, Wang Liang, Chen Gang, Wang Manli and a surgeon from the Bz City First People's Hospital were arrested one after another.
I thought the case was over, but who would have thought that this was the beginning of everything. First, Wang Liang’s wife was found dead at home on the fifth day after Wang Liang was arrested.
A stab wound, a fatal blow. On January 3, Chen Gang's uncle in Bz City was found dead in an underground garage.
The ax wound was a fatal blow from a fire axe, and a hole was opened in the chest. Today, January 7, Zhao Dong and his wife, who had a herbal medicine trading business with Wang Liang's wife, were found dead on the kang of their home.
"We go to the mountains to collect herbs every Wednesday. I didn't see Lao Zhao this morning, so I came to his house to look for him... I didn't expect..." The person who reported the crime was Zhao Dong's neighbor Sun Zhiyou, who had also been with him since he was a child. Those who grow old become young.
The two often go to the mountains together to collect herbs and then come back to sell them.
"Don't you usually have contact with each other?" It's been more than a day or two since Zhao Dong was killed. The blood on the ground has dried. If it hadn't been winter now, the body would have rotted long ago.
"In recent years, those who have gone out to work in the villages and those who have gone to college have gone to college. Now there are only about 20 families left in the villages." Sun Zhiyou is nearly 60 years old. He has been working hard all year round, making him look at least 70 years old. look.
"Lao Zhao and I are the youngest in the village now."
"We usually have nothing to do except collecting herbs. It's quite normal not to see him for three to five days." The person responsible for questioning Sun Zhiyou was Chen Kang, a detective from the Second Criminal Investigation Division of the Provincial Department, Li Donglin's subordinate: "When was the last time I saw him?"
"Two days ago, the morning before yesterday, I saw him adding fodder to the cattle." The inquiries from outside did not affect Lu Chuan's on-site survey.
"Ding!"
"Advanced mission: Complete a routine on-site investigation, combine three murder cases, discover valuable clues, and assist the task force in solving the case." After these several on-site investigations, Lu Chuan is basically certain that the murderer who killed Zhao Dong and his wife was The murderer who killed Wang Liang's wife and Uncle Chen Gang should be the same person.
The other party's methods of committing crimes are quite agile. Judging from the traces of murder at the scene, the murderer and Zhao Dong and his wife should have known each other.
When Zhao Dong was killed, he was sitting cross-legged on the kang. His wife sat beside the fire bed. The murder weapon used by the murderer was Dong Zhao’s kitchen knife.
A slash of Zhao Dong's neck was fatal. Later, when Zhao Dong's wife wanted to escape, he chopped Zhao Dong's wife on the head with a kitchen knife.
The killing was clean and neat, without any hesitation. If the scene could be reconstructed, the murderer should have picked up the kitchen knife on the stove after entering the door, entered the back bedroom, and killed people directly.
At the same time, this person illegally paid attention to self-protection. He wore gloves when committing the crime and did not leave any fingerprints. There were footprints, which were consistent with the footprints at the two previous scenes.
Lu Chuan felt that the work he could do was limited in terms of taking photos and collecting footprint information. Because he has already done this kind of work on both sides.
The first pass was to re-examine the scene where Wang Liang’s wife was killed. The second time was to investigate the scene where Uncle Chen Gang was killed. This is the third time.
"How's the situation?" Li Donglin watched Lu Chuan's performance in investigating Chen Gang's basement in Bz City, as well as his subsequent fingerprint identification analysis and physical evidence analysis.
After returning to the provincial office, Li Donglin deliberately checked Lu Chuan's information again. This check didn't matter, it really shocked Li Donglin.
What shocked Li Donglin was not that Lu Chuan became a full-time officer just after joining the police, nor was it the third-class merit medal. It was Zhang Yuanchao's evaluation of him.
Lu Chuan is not only proficient in on-site investigation and fingerprint identification analysis, but also proficient in skeletal identification and analysis. No one knows who Zhang Yuanchao is and what kind of expert he is than Li Donglin, who is also a technical expert.
Being recommended by Zhang Yuanchao to help the Tianzhou City Criminal Investigation Detachment conduct skeleton analysis, Lu Chuan's skills are definitely top-notch.
That's why Li Donglin and the Haizhou City Criminal Investigation Detachment called for Lu Chuan. As he expected, Lu Chuan did not disappoint him.
In the murder case of Wang Liang's wife, Lu Chuan determined the basic characteristics of the other party based on the footprints. However, these alone are not enough.
Taking a deep breath, Lu Chuan nodded heavily: "It's still him." Or is it him? ! After receiving the information confirmation, Li Donglin's heart seemed to be clenched tightly, and he missed a beat.
The man Lu Chuan talked about seemed to appear in front of Li Donglin again.
"Male, 1.75 meters tall, weighing about 80 kilograms, aged between 40 and 45 years old."
"The walking posture is slightly splayed, the right shoulder is sloping, and he is left-handed." This is the suspect's characteristics that Lu Chuan judged at the current investigation site based on the analysis of the footprints and the wound condition of the deceased.
The analysis of height, weight, and age is relatively simple. The murderer's shoe prints on his right foot are heavier than those on his left foot, but there are no signs of leg or foot disease.
It should be that the right shoulder has been under heavy pressure for a long time, resulting in some right sloping shoulders. The wounds of the deceased were all started on the left side, and were drawn diagonally to the right. This is the mark left by a left-handed person using a knife.
None of the suspects in Li Donglin's possession matched this information.
"Are there any fingerprints?" Lu Chuan shook his head: "Same as the last two times, the murder weapon used by the murderer was a kitchen knife from the deceased's home or a weapon readily available nearby."
"Wearing gloves, the murder weapon was discarded directly at the scene. It came and went quickly. Apart from contact with the murder weapon, no traces of contact were left." No matter how good a spot investigation is, there must be traces of contact between the murderer and the surrounding environment. , it is possible to find clues.
The other party, except for the murder weapon that was lost at the scene, did not touch anything. Nothing was left but footprints on the ground.
