After listening to Lu Chuan's words, several thoughts flashed through Qin Hui's mind, but each thought was very vague. It seemed that he had caught something, but he didn't catch anything.
Lu Chuan continued his analysis.
“Assuming that what Xi Mengyao said is true.”
“There were indeed three suspects at the scene of the 116 case, so we boldly assume that these three suspects are Tian Three suspects in the murder case in QZ City. "These three people committed the crime in QZ City. They must have known that the school's surveillance was damaged."
Qin Hui nodded.
"This is what we also judged back then. The three people climbed over the wall and entered the girls' dormitory to commit crimes. They must have known in advance that the surveillance cameras on the school wall had been destroyed."
"They knew that through The wall would not leave traces when it was rolled into the dormitory, so the time chosen to commit the crime was that time."
"But when the camera on the wall was pulled down, anyone passing by could actually see it. Therefore, it is very difficult to narrow down the scope of criminal suspects only from this aspect."
Lu Chuan agreed with Qin Hui's analysis.
But then there’s one more thing.
"Window, the window in the dormitory where the crime occurred was not locked internally."
This point...
Qin Hui also considered this point back then.
“The boiler of Qinzhou Vocational and Technical College is burned by itself, and the temperature is relatively high, so many dormitories open the windows to sleep at night.”
Qin Hui and others confirmed this on the second day after the incident. Not only the dormitory where the incident occurred, but also the dormitory next door and many dormitories next door would leave a gap in the windows.
Okay, Lu Chuan also nodded in agreement.
"Third, the murderer was able to knock out 6 people without disturbing anyone in the dormitory. The fundamental reason is that the 6 students drank alcohol that night, right?"
This...
Qin Hui nodded, it is true.
No matter how cautious the murderer was, there would still be some noise when climbing over the wall and through the windows. If the six people in the dormitory had not been drinking, they would not have noticed it at all.
"So...Qin detachment, surveillance, windows, and drinking, three coincidences came together and finally allowed the murderer to succeed, right?"
This...
Qin Hui's scalp was numb at the moment.
After working as a criminal police officer for so many years and solving so many cases, Qin Hui certainly doesn't believe in coincidences.
As long as there are too many coincidences in any case, it is definitely not a coincidence.
This is the experience Qin Hui has summed up over the years.
And what is going on with all this?
That innocent smiling face became terrifying for the first time in Qin Hui's mind.
Is it really her?
But...
How is this possible!
Xi Mengyao was indeed the victim at the time.
The evidence that she was assaulted is conclusive.
The scar on the head is also confirmed. The scar that was sutured eight times is still there.
It was Qin Hui who sent someone to take her to the hospital.
But if it wasn’t her... who else could it be?
Everyone else is dead.
The more Qin Hui thought about it, the more scared he became.
After a while, Qin Hui said: "Lu Chuan...evidence..."
"We need evidence..."
Yes, Qin Hui is right, and Lu Chuan can also understand Qin Hui's mood at this moment.
Three years have passed and the case has not been solved. The only survivor may be the murderer. No one can bear to leave him alone.
As for the evidence Qin Hui said, it may be available soon.
“Do you still remember the photos I took during the autopsy in the morning?”
Lu Chuan has the WeChat accounts of Qin Hui and Wang Ruiqing.
“The first photo is a photo of the female victim of Tianzhou City’s Miemen case whose lower body was injured.”
“The second photo is of the relevant parts of the two victims of the 116 case. Photo. "What's the difference?"
Wang Ruiqing is a current surveyor and is very sensitive to this aspect.
"Scars!"
"The first photo has scratches, which should be scratches caused by friction after the suspect shaved his body hair."
"There are no scratches in the second photo."
Yes!
Lu Chuan gave Wang Ruiqing a thumbs up.
"Brother Wang is right."
"No hair of the suspect was left at the scene of the 116 case. This is very difficult to do in accidental murder cases."
Wang Ruiqing and Qin Hui nodded, it was indeed the case.
Because even if there are no sperm spots, what about body hair?
After severe friction, it is very easy for body hair to fall off, especially the hair on the lower body.
Moreover, the murderer is difficult to clean up.
But the problem is that there is no trace of this at the scene of the 116 case.
“So, I have a bold guess.”
“The murderer of the 116 case is very likely to be only one person, and this person may be born without body hair!”
"There were three murderers in the Tianzhou City Massacre Case. One of them was the murderer in the 116 Case. The other two were not born hairless, but they shaved off their lower body hair when they committed the crime."
"But the other party ignored one point. Even if there is no body hair, because the roots of the body hair cannot be completely removed, when committing a crime, it is easy to cause friction scars on the victim's lower body due to severe friction."
...
Boom!
Lu Chuan's words were like a bomb that blasted into the minds of Qin Hui and Wang Ruiqing.
The expressions on their faces suddenly changed and they were very ugly.
Lu Chuan looked at the two of them in surprise.
My own guess...
Is it so powerful?
"Brother Wang, you..."
Wang Ruiqing replied with a wry smile after a while.
"Xi Mengyao's stepfather... was born bald..."
Lu Chuan: "..."
QZ City Criminal Investigation Detachment.
In the office, Qin Hui and Lu Chuan were deducing the case.
“Assuming our guess is correct, why did Xi Mengyao do this?”
Wang Ruiqing couldn't understand.
Lu Chuan couldn’t understand either.
If Xi Mengyao is an accomplice and the perpetrator is his stepfather, then many things can indeed be explained.
For example, Xi Mengyao could tell his stepfather about the damaged camera and the open window.
Moreover, in order to cooperate with her stepfather in committing the crime, Xi Mengyao deliberately got the other five people drunk on that day in the name of their birthday.
But why?
What was Xi Mengyao’s motive for committing the crime?
"Now all this is just speculation, just like what Captain Qin just said, evidence."
Lu Chuan only had suspicions, but there was indeed no substantial evidence.
Qin Hui put out the cigarette butt and took a deep breath: "No need to wait, just arrest the person. We will know after the first trial."
"Maybe there's no need to arrest people."
Lu Chuan has a safer way.
"No matter whether our guess is true or not, if the murderer in the 116 case is indeed Xi Mengyao's stepfather, then as long as we get his shoe prints and the shoes left by the suspect in the Tianzhou City Massacre Case By comparison, we can determine whether he is the murderer of the Tianzhou City massacre."
"As long as this is confirmed, it is impossible for the other party to deny it."
This plan is obvious! It is much better than directly interrogating Xi Mengyao or directly arresting Xi Mengyao's stepfather.
"Okay, I'll do this." (End of Chapter)
