Listening to Lu Chuan, a few thoughts flickered through Qin Hui’s mind, but each thought was very vague, as if he had grasped sothing, yet nothing at all.
Lu Chuan continued to analyze.
"Suppose everything Xi ngyao said is true."
"There were indeed three suspects at the cri scene of Case 116, so let’s boldly assu these three suspects are the sa ones from the Tianzhou City massacre case."
"These three committed the cri in Qinzhou City back then, they must have known that the school’s surveillance caras were broken, right?"
Qin Hui nodded.
"We made the sa judgnt back then. The three climbed over the wall to enter the girls’ dormitory for the cri, knowing in advance that the surveillance caras on the school’s wall were damaged."
"They knew climbing the wall into the dormitory wouldn’t leave traces, so they chose that ti to commit the cri."
"However, the caras hanging down from the wall could be seen by anyone passing by, so solely identifying the suspect based on this was extrely difficult."
Lu Chuan agreed with Qin Hui’s analysis.
But there was another point.
"The windows, the windows of the cri scene dormitory were not locked from the inside."
This point...
Qin Hui had also considered this point back then.
"The Qinzhou Vocational and Technical College used its own boiler, which was quite warm, so many dorms would sleep with the window open at night."
The day after the cri, Qin Hui and others confird this. Not only the cri scene, but many of the neighboring dormitories also left a gap in the window open.
Good, Lu Chuan nodded in agreent with this point too.
"Thirdly, the reason the killer could render the six students unconscious without alerting anyone in the dorm was because the students drank alcohol that night, right?"
This point...
Qin Hui nodded, it was indeed the case.
No matter how cautious the perpetrator was, there would have been so noise climbing over the wall or window, and if the six in the dorm hadn’t been drinking, they shouldn’t have remained unaware.
"So... Captain Qin, the caras, windows, and drinking, these three coincidences combined allowed the killer to succeed, right?"
This...
Qin Hui’s scalp tingled at that mont.
Having been a detective for so many years, solving so many cases, Qin Hui didn’t believe in coincidences.
If there are too many coincidences in a case, it’s certainly no coincidence.
This has been Qin Hui’s summary of experience over the years.
And all of this, what’s going on?
That innocent smiling face had beco terrifying in Qin Hui’s mind for the first ti.
Was it really her?
But...
How could this be possible!
Xi ngyao was indeed a victim at the ti.
The evidence of her assault was solid.
The scar on her head was also true, now stitched with eight stitches.
It was even Qin Hui who sent people to take her to the hospital at the ti.
But if it wasn’t her... who could it be?
Everyone else was dead.
The more Qin Hui thought about it, the more frightened he beca.
After a long pause, Qin Hui spoke: "Lu Chuan... evidence..."
"We need evidence..."
Yes, Qin Hui was right, and Lu Chuan could understand his feelings at the mont.
Three years, and the case remained unsolved, with the only survivor possibly being the perpetrator, anyone would be unsettled.
As for the evidence Qin Hui spoke of, maybe it would soon appear.
"Rember the photos I took during the autopsy this morning?"
Lu Chuan had both Qin Hui’s and Wang Ruiqing’s WeChat.
"The first photo is of the female victim’s genital injury in the Tianzhou City massacre case."
"The second photo is of the relevant parts of the two victims in Case 116."
"What’s the difference?"
Wang Ruiqing, being from the Cri Scene Investigation, was very sensitive to this aspect.
"Scars!"
"The first photo has abrasive scars, likely caused by the suspect shaving body hair and then causing frictional injuries."
"The second one doesn’t."
Exactly!
Lu Chuan gave Wang Ruiqing a thumbs up.
"Brother Wang is right."
"No body hair was found on the scene of Case 116. In cases of sexual cri, it’s very hard to achieve this."
Wang Ruiqing and Qin Hui nodded, it was true.
Because even if there were no sen stains, what about body hair?
Given the intense friction, body hair shedding, especially pubic hair, is very likely.
Moreover, the killer would find it difficult to clean up completely.
But the problem was, there weren’t any traces of this in the Case 116 scene.
"So, I have a bold guess."
"The killer of Case 116 might just be one person, and this person could be naturally hairless!"
"There are three killers in the Tianzhou City massacre case, one of them is the killer in Case 116, while the other two aren’t naturally hairless, but they shaved off their pubic hair during the cri."
"But the counterpart overlooked one thing, even without body hair, the roots can’t be completely removed, in the act of cri, with intense friction, it could easily cause friction burns on the victim’s genitals."
...
Boom!
Lu Chuan’s words felt like a bomb exploding in Qin Hui and Wang Ruiqing’s brain.
The two turned pale and their expressions were very unsettling.
Lu Chuan looked at them in surprise.
His own speculation...
Was it that powerful?
"Brother Wang, you..."
Wang Ruiqing responded with a wry smile after a while.
"Xi ngyao’s step-father... is naturally bald..."
Lu Chuan: "..."
The Qinzhou City Criminal Investigation Team.
In the office, Qin Hui and Lu Chuan were deducing the case.
"If our guess is correct, why would Xi ngyao do such a thing?"
Wang Ruiqing couldn’t figure it out.
Lu Chuan couldn’t either.
If Xi ngyao was an accomplice, and the perpetrator was her step-father, then a lot of things could indeed make sense.
For instance, the damaged caras and the open windows could have been inford to her step-father by Xi ngyao.
And Xi ngyao could have cooperated with her step-father’s cri by intentionally using her birthday as an excuse to get the other five drunk that day.
But why?
What was Xi ngyao’s motive for the cri?
"All of this is just speculation, as Captain Qin just said, evidence."
Lu Chuan was rely suspicious but indeed lacked concrete evidence.
Qin Hui extinguished his cigarette, taking a deep breath: "No need to wait, just arrest soone and interrogate, then we’ll know."
"Maybe we don’t have to arrest."
Lu Chuan had a more prudent approach.
"No matter if our guess is true or not, if the perpetrator of Case 116 is indeed Xi ngyao’s step-father, then by simply obtaining his shoe print and comparing it with the one from the Tianzhou City massacre suspect, we could confirm if he is the killer."
"Once confird, the other party won’t be able to deny it!"
This plan was obviously much better than directly interrogating Xi ngyao or arresting her step-father.
"Alright, I’ll handle this."
