After investigation, Liu Xiaolin did not have the time to commit the crime that night, but Liu Xiaolin's husband was not at home. He said that he was on duty at the unit, but there was no one to corroborate. Could it be that Gu Dahai found out about the ambiguous relationship between his wife and Zhang Yongcheng and killed him in a fit of anger and buried his body? ”

At the same time, during the visit among the villagers, the police also found that Zhang Yongcheng was not the only one who had a personal affair with Liu Xiaolin. Liu Xiaolin's former partner of mountain goods, Han Zhigang, also had an affair with Liu Xiaolin. And according to Liu Xiaolin, Han Zhigang is extremely possessive, the legendary domineering "bandit" kind - if you follow me, you are not allowed to follow others. Liu Xiaolin had no idea of divorcing Gu Dahai, Han Zhigang often ran to Liu Xiaolin when Gu Dahai was at home, Liu felt annoyed, and later turned to partner with Zhang Yongcheng, Han Zhigang also came to warn Liu Xiaolin. ”

On the night of Zhang Yongcheng's disappearance on June 11, Han Zhigang's younger brother said that he had seen his brother at 10 o'clock and that he was indeed at home. But strangely, the day after Zhang Yongcheng's body was found by the police, Han Zhigang told his family that he was going to Shandong to study his daughter at university, but he left home and could not be contacted on his mobile phone. It was the middle of June, and the university was about to go on vacation, so it was completely unreasonable to go to see my daughter at this time. Moreover, who would go to a foreign country and turn off their mobile phone? ”

To sum up, Liu Xiaolin's husband Gu Dahai and former partner and ambiguous partner Han Zhigang are both suspected of committing crimes. But because Han Zhigang has not returned, there is no way to interrogate him. With Zhang Yongcheng, what are the entanglements between these three men and one woman? Who is the murderer of Zhang Yongcheng? The case-handling personnel feel that Liu Xiaolin should be the breakthrough point in the case. In addition, Liu Xiaolin seemed to have concealed something during the interrogation, so under the attack of multiple rounds of psychological warfare, Liu Xiaolin said: Two kitchen knives in their house were missing, and the time of disappearance was after Zhang Yongcheng's body was found! She was afraid that her husband Gu Dahai was the real murderer, so she didn't dare to say it before. ”

At this time, Gu Dahai's younger brother also told the police that his brother had mysteriously handed over two knives to him and asked him to keep them secret. However, after comparing the wounds of the deceased, it was found that there was no match. Gu Dahai said that he hid the knife because he was afraid that others would think that he was a murderer, because the bloody clothes were found in his house, and he was afraid that others would say that he killed Zhang Yongcheng because of economic disputes. ”

"The case was at an impasse for a while. However, the investigators used an ancient ploy and soon found the real culprit. The ploy of the police is to lure the snake out of the hole. Because Han Zhigang is very suspicious, the police deliberately released the news after communicating with Liu Xiaolin and Gu Dahai, saying that the murderer of Zhang Yongcheng's case has been caught, and it is Gu Dahai. ”

Sure enough, on the third day after the news was released, Han Zhigang returned to Changbai Mountain. In further police visits, a key piece of evidence emerged - a villager said that on the night of June 11, Han Zhigang had borrowed their family's wheelbarrow from him, saying that he was going to carry sand, and that he had washed it and returned it the next day. The appearance of the wheelbarrow has cleared up the mystery in many cases - the 100-kilogram Zhang Yongcheng may have been transported by the murderer to the sand and clearing with a wheelbarrow. Although Han had cleaned the wheelbarrow, the police had recovered a little of Mr. Zhang's blood near the tape under the body. ”

"The only blood stains on the wheelbarrow only indicate that Zhang Yongcheng's body may have been transported by wheelbarrow. Soon, the investigators who had obtained the search warrant went to Han Zhigang's house to conduct a carpet search, and finally dug up two bloody knives under the bricks of a simple shower shed in his yard, and the blood on them was Zhang Yongcheng's. At this point, Han Zhigang, the murderer of Zhang Yongcheng, was finally locked. ”

Han Zhigang confessed that his motive for killing was because he saw Liu Xiaolin and Zhang Yongcheng walking very close, which made him crazy with jealousy. After he made up his mind to kill Zhang Yongcheng, he dug a deep pit in the open space next to the railway. On the evening of June 11, he carried a knife and first looked for him at Zhang Yongcheng's house, but he was not at home. At this moment, he saw Zhang Yongcheng happen to come out of Liu Xiaolin's house, and the jealous Han Zhigang rushed up and stabbed Zhang Yongcheng a few times, and Zhang Yongcheng fought with him, and Zhang Yongcheng's coat happened to be thrown under the firewood stack of Liu Xiaolin's house during the struggle. Zhang Yongcheng found a gap and ran to the position of the sandpile, Han Zhigang chased him and gave him a few knives, Zhang Yongcheng died, and the blood seeped into the sand. Then, Han Zhigang went home to push the wheelbarrow, but he didn't expect his brother to just bump into him, and thought he was at home. Then Han Zhigang took a shovel, covered Zhang Yongcheng with a plastic sheet, and pushed him into a pre-dug pit with a wheelbarrow and buried him. ”

"Magical, you say, isn't it magical? I think it's weird, if the police have such ability, they are still worried about what unjust cases, doubtful cases, can be solved in minutes. ”

I nodded thoughtfully, and at the same time looked at the old man lying on the ground, there was still no movement, Zhang Bin also turned his head and swept his eyes, and after seeing that there was no reaction, he continued to talk to me.

"The case mentioned below happened in Hubei, the West Lake Scenic Area in Tianmen, Hubei, is a place where local residents often go to relax and have fun. The West Lake is not big, there is a bridge on the side, and on the other side of the bridge is a back moat river, which is connected to the West Lake. On March 27, 2000, an old man who salvaged garbage in the West Lake Scenic Area found that a humanoid object he had seen on the other side of the Houhao River two days earlier had floated under the bridge. They had seen this object before, and they thought it was a model or an inflatable and didn't care, but when they looked at it closely, the old man was frightened, because he confirmed that it was a corpse. ”

"The police quickly arrived at the scene and organized the recovery of the body. The body was found in a strange situation: a plastic bag over its head, a pink rope on its upper body, and naked on its lower body. Later, after a forensic examination, the deceased was a woman, 35 years old, and 158cm tall. The time of death was 8 days earlier, on March 19, but the cause of death was not drowning, but mechanical asphyxiation. Although the woman's body appeared to resemble a rape and murder, the police did not find any signs of sexual assault on her. ”

"As mentioned earlier, the first idea of this kind of case is to determine the source of the corpse, and generally the case can be solved by determining the source of the corpse. Theoretically, those who can complete the modus operandi of killing people and throwing corpses are generally acquaintances or people who have intersections with the deceased. The case-handling personnel were about to check the situation of the missing person, and suddenly remembered that a few days ago, the local TV station in Tianmen had published a missing person notice, and the situation of the missing person was consistent with the time of disappearance and the time of death of the female corpse. So the family was quickly contacted, and it was confirmed that the deceased was a 35-year-old housewife - Zhang Liping. ”

However, the police's original idea that finding the source of the body would solve the case quickly was shattered. This case is far more complicated than imagined, and the key to solving the case is hidden in the most corner of logic, waiting for the investigators to find out. ”

Since the source of the body was determined, the police quickly restored the situation on the day of Zhang Liping's disappearance. She is a housewife, her husband runs a small business, she has 2 daughters, and the family is harmonious. On the afternoon of March 19, through the surveillance of their community, the police found that she had left the community. Then at around 2 o'clock, she appeared one after another in the monitoring of the road, and at 2:14, in the probe of Yamen Road, her figure appeared for the last time, and she was never seen on all the surrounding roads again. From this, the police deduced that she should have disappeared after 2:14 p.m. ”

The area where Zhang Liping disappeared is the local city center, which is very lively. In broad daylight, if any vicious robbery and murder occurs, it is impossible not to attract everyone's attention. And with the visit to Yamen Road, where she was last seen, and the Houhao River, where the body was dumped, the police did not find any valuable clues. Then it is very likely that Zhang Liping followed an acquaintance to leave the main road with a probe, and then was killed. ”

So, the police still focused the investigation on Zhang Liping herself to see if there were love killings, vendetta killings, and financial killings. The first person to be suspected was her husband Zhang Shaobo. However, Zhang Shaobo happened to be on a business trip in Xi'an at the time of the crime, and there was no time to commit the crime, and according to the investigation, the relationship between the two was very good, and neither party had an extramarital affair. And Zhang Liping has no job, and she has no enemies. The husband and wife ran a stationery store together, and the business was doing well. Later, at the end of 12 years, their store was transferred to Zhang Shaobo's younger brother Xiao Zhang. ”

Xiao Zhang was also suspected by the police because he had a certain motive: he owed his brother and sister-in-law 80,000 yuan when he took over the store, but he was quickly ruled out because he had an alibi. Acquaintances have been investigating for a month, but they still can't find anyone who has the possibility of committing the crime. The investigators decided to change their way of thinking about the investigation and turned to believe that it was an accidental incident that led to Zhang Liping's killing. So, they called up all the videos that recorded Zhang Liping's final route again, and drew a road map, going from store to store along the way to find clues - since it wasn't an acquaintance who took Zhang Liping off the main road, could it be an accident after she entered a certain store? ”

There are dozens of shops on this 200-meter "road to death", if Zhang Liping really caused death in one of the shops on this road, then what will she encounter? Police surveillance found one of her unusual behaviors - Zhang Liping had walked back and forth several times on a short section of Yamen Road. At this time, they learned from her husband that Zhang Liping's usual hobbies are fiddling with flowers and plants and shopping, and the flowers at home have never stopped. The police's eyes lit up, because there were 2 flower shops on that short road, so did Zhang Liping have an accident in the flower shop? ”
