CHAPTER XIX

Raising dates in the shade

The special case team and the Xiaocheng police conducted an inquest and analysis around the deceased's bicycle.

The bicycle is supposed to have been discarded by the murderer, who threw the deceased's bicycle and his own high heels into the garbage pool after the killing. Zhao Xin confessed that he did not ride the bicycle after picking it up, because the tires were deflated and there was some garbage on the wheels.

Police failed to extract the suspect's fingerprints on the handlebars, and the dirt on the footpegs provided little clue.

The garbage pool was more than half a meter high, and the murderer had to lift or lift the bicycle to throw it into the garbage pool, and after a comprehensive investigation, the police accidentally found trace oil stains on the beams and tripods on the bicycle, and the identification results showed that they were diesel.

Su Mei said: "The diesel fuel on the bicycle is likely to be left behind by the murderer. ”

"If the tires of the car are deflated, could the diesel fuel be contaminated by the deceased when he repaired the car?" ”

Bao Chu said: "The tires are punctured and you generally have to find a car repair shop, when the old horse drank the wedding wine at night, and the car repair shop was closed. ”

Professor Liang said: "I had the courage to reason, the old horse was about to ride home after drinking the wine, and found that the tire was punctured, and I happened to meet an acquaintance, who should have a car, maybe a tractor, or an agricultural motor tricycle, in short, it was a diesel car, and the old horse never returned. ”

The old director said: "We must adjust the direction of the investigation, and this case is very likely to be committed by an acquaintance." ”

After investigation, it was found that most of the people who attended the wedding banquet that night were relatives and friends from rural areas, and many of them came by tractors or agricultural motorized tricycles. The police drew up a detailed list for investigation, and eventually, a suspect surfaced.

This man is Lao Ma's son-in-law, named Li Qing, who has a farm motor tricycle and sells vegetables for a living. He usually doesn't drink a drop of alcohol, and sat at a table with his father-in-law Lao Ma at the wedding banquet, and both of them drank a lot of wine that night. Someone confirmed that after the banquet, Lao Ma's bicycle tire was punctured, and Li Qing wanted to send his father-in-law home, but his father-in-law did not agree, and the two argued for a long time.

The old horse said, "You don't care about me, I can go by myself." ”

Li Qing said: "Dad, your car is broken and you can't ride, get on my tricycle!" ”

Li Qing was the last person to see the deceased's old horse.

However, Li Qing denied this, claiming to the police that after the wedding banquet, Lao Ma insisted on going home by himself and did not let Li Qing send him off. The police learned from the external investigation that Lao Ma's two sons were not filial, and Lao Ma had just died, so the two sons started the idea of the ancestral house and discussed selling it for money. Daughter Ruiwen came to the public security bureau many times to demand severe punishment of the murderer, and every time she burst into tears, urging the police to solve the case as soon as possible.

On the pretext of informing the case of the progress of the case, the special case team summoned Li Qing and Ruiwen to the public security bureau for separate interrogation.

Su Mei said: "On the day of the wedding wine, did your husband have any abnormal reactions after coming home?" ”

Raven said: "He drank some wine, and when he came home, he went to sleep, and I got up in the middle of the night to let him drink water, and when I saw him sitting at the head of the bed, I was startled, and asked him what he was doing, and he said he had a headache, and then he went to sleep." ”

Su Mei cautiously asked, "Your husband, Li Qing, do you usually have the habit of wearing women's clothes?" ”

Raven said: "What is he doing as a man wearing women's clothes, what do you mean by this?" ”

Bao Chu said: "Li Qing, how is your relationship with your father-in-law?" I heard that you used to run transportation and traffic vegetables together. ”

Li Qing said: "I went to other places to pull a cart of celery and potatoes back to sell, and sometimes I called my father-in-law to escort the car and let him help. ”

Bao Shu took out a pair of high heels, stared at Li Qing and asked, "Can you cooperate with us to do an experiment and try wearing these shoes." ”

Li Qing was a little flustered, sweating on his head, his eyes dodged and he didn't dare to look at the shoes, he said: "These are women's shoes, what am I wearing them for?" ”

Li Qing's feet just fit into the high heels, and he walked back and forth on the dirt pavement at the request of the police. Professor Liang noticed that when Li Qing was walking, he deliberately adjusted his posture, his stride was larger than usual, and he also fell. Once the shoe prints are obtained, the next step is to compare and analyze a series of data.

Trace identification experts use the Zernik moment to represent and identify the shape of the shoe print, divide the shoe print into several independent lines, expand the angle with reference to the common coordinates, record the data, and then compare the characteristics of the shape and scale, and accurately calculate the subtle edges. Through geometric theory, the area, perimeter, long axis, short axis, main axis direction, convex and concave area, compactness, and solidity of the shoe prints were compared one by one, and finally a preliminary conclusion was drawn that Li Qing's shoe prints were more consistent with the shoe prints at the scene of the crime, with a similarity of 80%.

Su Mei said: "Cinderella found her crystal slipper, devoured and we found Cinderella." ”

"The next step is to do a DNA test to confirm whether Cinderella is him," Professor Leung said. ”

Bao Chu said: "How can this be, the son-in-law raped and killed his father-in-law, it is unbelievable." ”

Hualong said: "Are there still few perverted murderers encountered by our special case team? ”

DNA testing takes time, and the police decided to secretly monitor the suspect, Li Qing.

The civil affairs department cooperated vigorously to help find the best monitoring point. There is a feed processing factory opposite Li Qing's house, and there is a ventilation attic on the plant, and the monitoring point is set up in the attic. From here, from a high vantage point, the courtyard of Li Qing's house can be said to be unobstructed, and two policemen set up high-powered binoculars that can take pictures to monitor Li Qing's house 24 hours a day. Their main task is to keep track of the suspect's whereabouts and prevent escape.

On the third day of surveillance, the police reported an extremely strange clue.

It was afternoon, and Raven closed the door and locked it, which alerted the surveillance officers. After Ruiwen entered the house, she said something to Li Qing, and Li Qing looked very reluctant. Next, a surprising scene happened. Raven took off her pants and lay on her back on the bed, monitoring the police thought

The couple were going to have sex, but who knew what Raven had pulled out of her body. Li Qing was indifferent, and after a while, he took the thing and put it in his palm, frowned, and swallowed it with a tilt of his neck.

The surveillance personnel filmed the whole process, and after enlarging the photo, it was found that the thing was a round red date.

Su Mei looked at the photo and said, "I'm going to vomit, how dare I eat dates in the future." ”

Bao Chu said: "Why do you want to eat this? It's weird. ”

Hualong also looked at the photo and said, "This should be a dried jujube, soaked for a long time, it has become round and big." ”

Professor Liang is well-informed and said: "This is jujube farming! ”

In the past, people believed in yin essence and aphrodisiac, so there was "raising jujube", also called "yin jujube" and "gan". There is a poem in Zhu Yun's "Collection of Poems of the River" in the Qing Dynasty that records the cultivation of jujubes: "Hong gradually persuades students to have contacts, and silkworms are written without oysters." Raising jujube Anyong also tastes twisted, and planting bamboo will cause the wind to be heard. ”

The "Collected Memories" written by Wang Jia of the Eastern Jin Dynasty also has a record of raising jujubes.

In the modern notebook "Night Rain and Autumn Lantern Record", there is also a similar description. The story is about a man named Jin Ding, who strayed into the lair of a thief. This Jiangyang thief also has the same hobby, he specially plundered two women and put them in the inner room, just to be able to eat "pickled dates". The two women complained to Jin Ding: "Master...... He likes to be too strange and likes to eat sweet. ”

Shaanxi folk also have the theory of raising jujubes, and there are also such records in the books of Shaanxi writers Chen Zhongzhong and Jia Pingwa.

The case was full of twists and turns, and the suspect Li Qing entered the police's sight, which was exciting, and he thought that it was not far from solving the case. However, the "jujube raising" incident that was photographed by the monitor seems to indicate that Li Qing is a sexual dysfunction patient. The couple has been married for many years and has never had children, the special case team has investigated this, Li Qing does have impotence and cannot get a normal erection, he once went to Xiaocheng People's Hospital for treatment, and the medical records archived by the hospital also confirm this.

has been married for many years, has no children under her knees, and her wife Raven wants to go crazy if she wants children. She made tiger head shoes in advance, bought small clothes, and even prepared 20 diapers. However, her husband Li Qing's illness was not good, and she underwent a neurological examination, psychological examination, liver and kidney function test in the hospital, and prescribed a lot of medicines, but her husband still couldn't get an erection and couldn't have a normal sex life.

Relatives, friends and neighbors all confirmed to the police that Ruiwen had gone to the slaughterhouse to buy a sheep whip, a donkey meat restaurant to buy a donkey whip, and a dog meat dealer in the west of the town to buy a dog whip.

When Raven went shopping, she would stand in a daze in front of a telephone pole with an advertisement for the treatment of infertility by an old military doctor.

Li Qing suffers from impotence, so how can he rape and kill his father-in-law, Lao Ma?

When the DNA test results came out, everyone was shocked, the semen in the body of the deceased Lao Ma was left by Li Qing!
