After informing them of the case, Su Ping led them directly to the scene of the crime in Lingyang District, while Xun Mu stayed in the detachment to deal with the lawyer, the suspect's family, and the deceased's family.

The lawyer said that the families of both sides were about to fight, which was a headache, Su Ping couldn't cope with this situation, and as for Brother Song, it was even more unsuitable, after all, Xiucai met a soldier, and it was unreasonable.

So Xun Mu can only stay and deal with it.

The scene was not close to the detachment, and it took half an hour to get there.

The police officers who stayed behind greeted them, tore off the temporary seals, opened the door and invited them in.

"There are not a lot of bloodstains, and it seems that Song Xiuzhen's knife wound is indeed not serious." Su Ping said: "The perpetrator couldn't kill Song Xiuzhen with a knife, but she knocked the knife off...... The perpetrator should not be much better than Song Xiuzhen in terms of fighting.

But he can't deal with Song Xiuzhen with a knife, how can he strangle people to death with his bare hands? After the deceased knocked the knife off, his physical strength was also at the limit? ”

Brother Song inspected the door lock for a while and said: "There is no trace of the door being pryed, and according to the husband of the deceased, they are all closed at home, and they have a strong sense of safety precautions, and strangers will not open the door when they knock on the door, so it is speculated that an acquaintance should have committed the crime." ”

"Acquaintances committed crimes......" Su Ping sighed, looked left and right, and found no clues, after all, the criminal investigation team of the sub-bureau had already investigated and the evidence was retrieved.

After a visit to the site, there was also no gain.

All clues still point to Ruan Xuanmin.

Until the end of the team, there was no breakthrough in this case.

Nine p.m., conference room.

Xun Mu was tired, obviously the families of both parties were not easy to deal with, and it took him a lot of energy.

At a glance, he knew that the team led by Su Ping was afraid that there would be nothing to gain, so he looked directly at Yan Zhongxin and asked, "Old Yan, you should have re-examined the corpse, right?" What do you think? What's the catch? ”

"Sort it off," Yan Zhongxin got up and said: "Song Xiuzhen has given birth, gave birth smoothly, and the shade is relatively relaxed, but the autopsy found that her perineum is still torn, in addition to the perpetrator's rough movements, and the victim's death has caused stress expansion and lubrication to disappear, the large diameter of the intrusion is also an important reason." ”

Qi Yuan opened his mouth.

This is a clue, the question is, if you have a definite suspicion of committing a crime and have certain objective evidence, it is better to say, otherwise how to investigate? Do you want the suspected target to take off their pants?

However, seeing that Xun Mu and the others all looked thoughtful, he didn't speak.

After being silent for a while, Xun Mu continued to ask, "What about the other things?" Anything else? ”

"There was a bruise on the back of the deceased's head, but it was not serious, there was no obvious damage to the brain tissue in the skull, and the skull was fine." Yan Zhongxin said: "Judging from the photos at the scene, it should be that he accidentally fell while pushing and shoving with the perpetrator, and the back of his head hit the coffee table."

After that, the perpetrator immediately seized the opportunity, rode on the deceased, strangled him to death, and then quickly raped the body and fled the scene.

In addition, the sharp weapon injuries on the victim's body are relatively superficial, the murder weapon is a single-edged fruit knife, which is not sharp, and it is speculated that the strength of the perpetrator should not be large, and judging the height by the direction of the sharp weapon, the perpetrator should be shorter than the deceased, between 1.55 and 1.6 meters, which does not match Ruan Xuanmin's height.

As for the shoe prints and bloody shoe prints on the ground, I speculate that either the perpetrator's feet were unusually large, or he deliberately wore shoes several sizes larger. ”

"The latter is more likely," Chai Ningning continued: "We have done a gait analysis of the footprints at the scene, and found that the perpetrator's gait was quite awkward, and the center of gravity was also unusual, which was speculated to be caused by ill-fitting shoes."

In addition, we extracted all the footprints at the scene through the electrostatic film sampling method, and found that one group, regardless of the shoe length, pattern style, and degree of wear, was consistent with the leather shoes worn by Ruan Xuan Min on the day of his arrest, proving that he had indeed entered the scene recently.

But the blood footprints, although the length of the shoes is the same as Ruan Xuanmin's, but the pattern style is completely different, and the degree of wear is not equal, I went to compare all the shoes in Ruan Xuanmin's house one by one, and there is no correspondence.

This leads to two possibilities: either the judgment of the 'one perpetrator' reached by the colleagues of the previous brigade was wrong, and Ruan Xuan Min was one of the perpetrators and participated in the murder, or Ruan Xuan Min entered it after the murderer left, did some finishing work, and deliberately left his own traces in order to impersonate the crime. ”

"Oh?" Xun Mu asked, "Which one do you think is more likely?" ”

"The latter," Chai Ningning said without thinking: "Judging from the traces at the scene, only one person is fighting with the deceased, and the other perpetrator can't be watching the play all the time, right?" So I think the latter is a lot more likely. ”

"Impostor." Xun Mu crossed his fingers: "Moreover, the culprit is not tall and his strength is not great, but that stick is particularly big." ”

The corners of Chai Ningning's mouth twitched and sat back.

Yan Zhongxin said: "In addition, I also re-evaluated the suspect, no problem, the suspect did completely lose sexual ability, the vulva was completely removed, and the urethral opening reconstruction was performed, and it was impossible for him to violate the deceased." ”

"Understood." Xun Mu bowed: "Then, the focus of the next investigation is to keep an eye on the balances and flows of various financial accounts and bank cards in the names of him and his family, and in addition, his home is also carefully searched."

If he is guilty of financial reasons, the culprit will definitely have to pay, either by transferring money or by cash. If the culprit chooses to repay the debt, Ruan Xuanmin will not be stupid enough to continue to blame him.

After all, admitting the guilt of impostor is much lighter than murder and rape of corpses, as long as he is not stupid, he should know how to choose. ”

Song Ge added: "On the other hand, Ruan Xuanmin's interpersonal relationship must also be investigated.

Impersonation is not necessarily due to financial reasons, but may also be emotional, such as the offender is an immediate family member of the ......"

"No," Xun Mu shook his head: "He has no son, just a daughter, and his father is in his hometown, so he does not have the conditions to commit a crime." As for the brothers...... There's no way he's going to take the blame for his brother, right? Unless he's a brother and a brother. ”

"It's hard to say," Su Ping took over, flipped through the investigation report, and said: "His younger brother, thirteen years younger than him, twenty-eight this year, unmarried, single.

At the same time, Ruan Xuan Min is still a traditional and pedantic man, with a strong concept of 'passing on the lineage', and colleagues in the brigade investigated and learned that he had a good relationship with his younger brother, if the criminal was his younger brother, he took into account his own situation, and then considered that his brother was still a bachelor, and he might not jump out and take the blame for his younger brother. ”

After a pause, he frowned again and said, "The biggest problem is, his younger brother ...... It's not in Yuqiao, it's in the magic capital. ”
