I thought that this homicide case had enough clues and could be solved quickly, but as the suspicions of the scene investigation and the suspicions of the autopsy continued to appear, it seems that this case is far from being as simple as we imagined.

"I heard you just say that you found the wounds caused by two single-edged daggers?" I asked directly.

Ren Qiushi nodded, beckoned to me, and motioned for me to walk to the dissection table.

I walked quickly to the front and my eyes fell on the female corpse in front of me.

The body of the female corpse has been cleaned and wounded, and it is no longer the bloody blur we saw at the scene of the crime.

The corpse is waxy yellow, which is formed by excessive blood loss and the loss of blood circulation due to the weight of the body.

There were more than a dozen puncture wounds on the chest and abdomen of the deceased, the wounds were distinct, and the flesh and skin were contracted, like grinning mouths.

Ren Qiushi said in a deep voice: "There were a total of twelve puncture wounds to the chest and abdomen of the deceased, and the cause of death of the deceased was the rupture of internal organs. The lower body was also stabbed several times, but it was difficult to discern the shape of the wound. ”

Ren Qiushi paused, his hand lightly rested on a stab wound on the deceased's flank, and said seriously: "After comparing it with the fruit knife found at the scene, the depth and length of the stab wound here are consistent with this fruit knife, and it can be judged that the tool that caused the injury is this fruit knife." ”

"This is the only one?" I frowned and asked.

Ren Qiushi nodded and continued: "That's right, there is only this one, although the other eleven stabbing injuries are also single-edged daggers, but they are inconsistent with the width of this fruit knife, and the injury tools should be another single-edged dagger." And the only stab wound left by this fruit knife was not fatal at all. ”

Ren Qiushi's words made me completely confused.

The fruit knife found at the scene stabbed the deceased in the flank, but it was not fatal at all. So who caused the other stabs? Where did the murder weapon go?

Ren Qiushi's expression at this time was the same as mine, and he was also confused, and he said in a deep voice: "These twelve stab wounds are all injuries before death, if it wasn't for the murderer using two injury tools, then the murderer is more than one person." ”

Ren Qiushi's remarks woke me up, and we also mentioned this point of view at the case analysis meeting just now. On the night of the crime, a total of three groups of people entered the scene of the crime, so does it mean that there is more than one murderer? !

The murderer was not a gang, then there was a murderer who first entered the scene of the crime, stabbed the deceased with an unknown person, and then dropped the fruit knife and fled.

Immediately afterwards, another murderer entered the scene of the crime and repeatedly stabbed the deceased.

Because all stab wounds are antemortem injuries, it is also the second murderer who caused injuries to the deceased's lower body.

If this is the case, then a myriad of possibilities arise for the nature of the case.

It is quite possible that the first murderer did not want to kill, but had a quarrel with the deceased, committed a crime of passion, and accidentally injured someone.

Then the second murderer really wanted to kill.

So the third batch to enter the scene of the crime, will it be the first murderer? After injuring someone, he fled out of fear and returned to the scene of the crime shortly after.

Or the third group of people who entered the scene of the crime were completely unrelated to the case? So why didn't this person call the police after he found out that the deceased had been killed?

It's all so strange that I can't think of a plausible explanation, and none of the speculations seem to be entirely in line with the circumstances of this case.

"What are you thinking?" Ren Qiushi saw that I hadn't spoken, and suddenly asked me.

I was stunned for a moment, came back to my senses, and after telling Ren Qiushi my thoughts, Ren Qiushi also fell into deep thought.

Fortunately, he didn't think about it for long, and quickly settled down and spoke slowly: "I extracted male DNA from the deceased's lower body, and there are also secretions from the deceased, indicating that the deceased was not dead when he had sex." In addition, I found some dander tissue in the right fingernail of the deceased, and the DNA has been sent for examination, which I believe will be the key evidence to lock down the suspect. ”

I nodded and said seriously: "As long as you find the corresponding person with these clues, everything will be clear." ”

"Is the time of death confirmed?" I asked again.

"The time of death was around ten o'clock in the evening." Ren Qiushi said in a deep voice.

"Ten o'clock...... We received the call to the police at 10:15, which means that when Bai Chuyun arrived at the scene and called the police, the deceased had just died fifteen minutes ago......" I suddenly muttered.

How many murderers are there? Who leaves the male DNA? Who do the bloody footprints, the fingerprints on the fruit knife, the cigarette butts without the ash belong to?

For a while, all the questions poured into my mind, if the male DNA was left by the murderer who accidentally injured people, then the second murderer who came to mend the knife, the motive for killing could not be emotional entanglement.

Now, even our only certain motive for killing is facing denial.

It seems that we need more intuitive clues.

learned from the mouth of the deceased's sister Bai Chuyun that after the deceased Bai Chuyue was widowed, the manager of the supermarket where she worked had a very good relationship with her, and she must know Bai Chuyue better and could get some clues through him.

It's already twelve o'clock at night, and it seems that the investigation can only wait until tomorrow, and by tomorrow, all kinds of inspection reports from the laboratory department will come out, which provides us with very important evidence to solve the case.

……

Early the next morning, when I was about to investigate the store manager of the deceased's workplace, there was a sudden good news from the Technical Investigation Division.

They hacked the deceased's phone and found that at 9:10 p.m. last night, the deceased had sent a message to a person nicknamed "store manager".

The content of the message is: "It's raining and the power is out, I'm scared at home alone, you come and accompany me." ”

If this "store manager" is the store manager of the deceased's work unit, then it can be intuitively seen from the content of the text message that the relationship between the deceased Bai Chuyue and the store manager is not ordinary, and it is very close.

The message was sent at 9:10 a.m., the rainstorm was around 8:30 a.m., and the power outage was 10 minutes later.

But Bai Chuyue's time of death was around 10 o'clock in the evening, what happened in this hour?

So could the DNA in Bai Chuyue's body be left by the store manager? So what role does the store manager play in this homicide case?

Although there are still many unanswered questions, as we lock down the key person of the store manager, we are ready to find a breakthrough in the case from him.

Now that the store manager is suspected of committing a crime, we did not choose to verbally summon him, and personally "visited him to send warmth" and brought him back to the criminal police team for investigation......
