Soon, the DNA identification results came out: the sperm spots on the bed and the tadpoles in the condom were both Shang Biao's.
The police suspected that Shang Biao killed the person, but Shang Biao insisted that he only "had sex" with Song Enhui and did not kill anyone. He also said that he had a car, a house, a wife and children, and he had a full sense of happiness and gain in life. , why do you want to kill someone who is so good?
Although Shang Biao's dog couldn't spit out any ivory from its mouth, what he said was not unreasonable.
The police could not find Shang Biao's motive for the murder, so they began to be suspicious.
But immediately afterwards, the police found a roll of tape and a piece of white nylon rope in the trunk of Shang Biao's car, which were exactly the same as the tape on the deceased's mouth and the nylon rope used to tie his hands.
The suspicion that had just been lowered suddenly skyrocketed again.
Shang Biao sighed, saying that he might have hit a ghost, and the yellow mud that fell off his crotch turned into shit.
Then he explained that that was the last time he met Song Enhui. Song Enhui said that it was inconvenient that there was no large supermarket near the Red Coral Community and many things were unavailable, so she asked him to help buy it on the way.
Shang Biao himself is not a petty person, so he bought more of everything when buying.
Song Enhui only took a roll of tape and cut a length of nylon rope from her car, saying she wouldn't need so much, and stuffed the rest into the trunk of Shang Biao's car. Putting these things in the trunk is not in the way, and they can indeed be used for emergencies, so Shang Biao has never thought of throwing them away.
There is nothing wrong with Shang Biao's explanation.
While the police were still doubtful, the on-site investigation report came out.
The report showed that no fingerprints or footprints were found at the scene, not even those of the deceased himself. It was obvious that the crime scene had been carefully cleaned.
This is very wrong.
After the Hushan police carefully sorted out the clues and information in the case from beginning to end, they soon became inclined to believe that Shang Biao was not the perpetrator.
As mentioned before, Shang Biao's motive for committing the crime is unknown. The possibility of it being for money is close to zero, but for sex? Shang Biao has already had sex with her, so why does he need sex?
Even if what Sang Biao told is a lie, there is no physical relationship between him and Song Jiying that goes beyond friendship. All of this is his fabrication. In fact, it is assumed that he covets Song Jiying's beauty and has been plotting against her. Unruly. Then when he met Song Zhiying for the last time, he raped her and then killed her to silence her.
The problem is: in sexual assault cases, criminals rarely wear condoms when performing sexual intercourse, almost none.
Even if Shang Biao is a maverick and does not follow the ordinary path, he is the only green among thousands of flowers, and he takes the initiative to wear a condom during the sexual intercourse, or wears a condom at Song Zhiying's "request", but afterwards, since he is right The site was carefully cleaned, so why did he still leave his used condoms behind?
Use it if you use it, keep it if you keep it, and why did you tie it with a knot? Is this because he is afraid that the tadpoles inside will be lost and evaporate, and that the police will not be able to extract his DNA?
As for tying used condoms into knots, Sang Biao said that he had never done this before and had no such "habit" at all. After having sex with Song Ji Young that day, it was Song Ji Young who took the initiative to tie the condoms. After it was pulled off his body, he didn't even pay attention to how to deal with it, and he didn't know if Song Zhiying had tied the condom.
At the same time, why didn't Shang Biao remember to clean up the semen spots on the thighs of the deceased and on the sheets?
There is also an alarm clock on the floor. The time displayed on it coincides with the last time Shang Biao saw Song Zhiying and had sex with her. This makes it difficult for the police to contact Shang Biao as a criminal suspect.
Why didn't Shang Biao remember to clean up the alarm clock?
He deliberately left an alarm clock to show the time of the crime, and truthfully reported the time of his last date with Song Jiying in his confession. These two basically consistent time points clearly hinted that Shang Biao was the criminal. No suspect would be that stupid.
In short, it is impossible for the suspect to leave so much evidence pointing to himself after cleaning the scene, let alone to leave crime tools such as tape and rope in the trunk of his car.
At the same time, the sheet on which the deceased was lying was relatively flat, with no signs of wrinkles or tears. This should not be the case if sexual intercourse or even a fight occurred on the bed.
The autopsy report also showed that there were no signs of struggle such as scratches or gouging on the body of the deceased, and no residual drug ingredients were detected in the stomach. Blood tests also found that the deceased had taken drugs or taken narcotic, hallucinogenic, or stun drugs before his death. drug.
In other words, it is very likely that the deceased was not raped before his death, but it is more likely that the deceased was voluntary and had a relationship with Shang Biao. In other words, Shang Biao’s confession is extremely credible.
Combined with the above-mentioned various "evidences" that appear to be logically contradictory and conflicting, the police quickly came to an inference: the crime scene of home invasion, robbery and murder was probably carefully forged. The person at the scene, the real culprit, had the purpose of framing Shang Biao.
This murderer achieved his goal of putting the blame on Shang Biao based on various evidences, but his logic was full of loopholes and made no sense. Even because of being clever and superfluous, it leads to logical paradoxes. The problem is that determining whether a person has committed a crime is mainly based on evidence, not logic.
Therefore, although the Hushan County police knew that Shang Biao was most likely not the murderer, they had to temporarily detain him until the real murderer was captured and brought to justice.
Therefore, Shang Biao, who thought he was more unjust than Dou E, was full of complaints, saying that the Hushan County police acted erratically and wrongfully accused him of murder.
When Yang Feng, Wang Xing, Lao Liu, and Ouyang arrived at the Hushan County Bureau, the investigators of the case were having a headache:
They asked Shang Biao to think carefully about who he had offended. Shang Biao racked his brains and couldn't think of anyone he had offended. He also said that he was a businessman, and what he values is that harmony is the most important thing, and harmony makes money. Who can he offend?
Even if he had conflicts with people, it was nothing more than some nonsense in business, such as the client being dissatisfied with his designed work or the company's services, dissatisfied with his high charges, and asking him to refund his money. Go kill someone and then put the blame on him?
For the purpose of giving it a try, the Hushan County Police asked Shang Biao to provide a list of several people who had had business quarrels with him, and then investigated them one by one based on the list.
As a result, none of these people had anything to do with Song Zhiying. Whether it was call records or social platforms, they had nothing to do with Song Zhiying. Some of them could provide direct evidence that they were not in Hushan County at the time, or that there was no time when the crime was committed. evidence.
The Hushan County police were at a loss as to where to start the investigation.
The arrival of Yang Feng and others just provided them with some new investigation directions. While they were on the road, they had carefully considered the case.
Wang Xing and the Hushan County Police basically have the same view:
Since the murderer deliberately put the blame on Shang Biao, the murderer is most likely the person Shang Biao has offended. This is an investigation direction. Of course, there must be an "acquaintance" relationship between the murderer and Shang Biao. At the same time, since there were no signs of struggle at the murder scene and the crime was committed indoors, the murderer and Song Zhiying should also have an "acquaintance" relationship.
However, as mentioned above, the investigation work initiated by the Hushan County Police based on this logical inference has reached a dead end.
Ouyang believes that judging from the fact that the murderer has cleaned the crime scene, the murderer has certain anti-reconnaissance capabilities. At the same time, although the murderer could think of a way to frame the crime, and pointed all suspicions at Shang Biao by forging the scene and arranging evidence, he ignored that the police handled the case not only with evidence, but also with logic.
Therefore, the murderer will not be a member of the police, or someone from other judicial systems who is familiar with the police's methods and methods of handling cases, nor will it be a "professional" who kills people to silence them, or even has never killed anyone before.
But the murderer is very likely to have been involved in the crime and has a criminal record. In other words, the murderer may have been in prison, or his friends or acquaintances are from the police. He has dealt with the police and heard some rumors about the police's methods of handling the case, but it is not complete. unprofessional.
Lao Liu believed that Song Zhiying asked Shang Biao to buy her tape and nylon rope. As a result, these two items became tools for committing crimes. She even left some for Shang Biao and stuffed them into the trunk of Shang Biao's car. ;Song Jiying
After having sex with Sang Biao, she took the initiative to dispose of his used condoms and tied a knot in the condoms. Could it be that Song Ji Young did this deliberately? .
Of course, this behavior may also be intentional when the murderer arranged the crime scene.
Let us first assume that tying the condom is the result of Song Zhiying's behavior.
In this way, will we draw an inference: In the conspiracy to blame Shang Biao, the deceased Song Zhiying herself was a participant and implementer?
Wang Xing was shocked and said that you think the deceased knew that he would blame Shang Biao before he was alive, and even planned this conspiracy with the murderer. The question is, who would be willing to blame his own death on another person? ?
Moreover, whether judging from Shang Biao's confession or the life trajectories of the two of them, they did know each other just two or three months ago. They didn't get along for a long time, and there was no conflict of interest between them. There shouldn't be any deep hatred that would lead Song Zhiying to have such thoughts and behaviors of "perish together" towards Sang Biao.
Even if there is some unknown deep hatred between them, Song Zhiying directly kills people. Since she has the thoughts and actions of "willing to die", surely she is not afraid of being sentenced to death after killing someone? Do you have to go to such great lengths to risk your own life?
Lao Liu shook his head, saying this is hard for me to understand, but things develop and change, movement is the movement of matter, matter is moving matter, nothing is static...
