Novel Bin Chapter 44 - 44: Locating the Murderer (1)
Since the results of the autopsy were out, the next step was to arrange for the investigation and arrest.
There were no fingerprints left on the deceased’s neck, so comparing the residual bodily fluids in the deceased’s body was the only method at the moment.
Chen Yan looked at Li Hong. “”The next step is to find someone who matches the DNA sequence of the body fluid in the deceased.”
“Okay, I’ll arrange this!”
Chen Yan nodded.” The main point is the construction workers on the construction site. They can be screened in the name of a blood test.”
Of course, Li Hong knew what Chen Yan meant.
Last night, only the workers were staying at the construction site. It was unlikely that the students would go.
“Also, let’s go to the scene now and check the floor where the victim fell.
In the morning, although Chen Yan found traces of the deceased crawling, because of the rain, the ground was slippery and muddy. The deceased did not leave any traces of falling on the ground.
The scene was still under lockdown.
The newly renovated teaching building had a total of six floors and had now become a framework.
The building was relatively spacious and airy.
On the second floor of the teaching building directly opposite the crime scene, Chen Yan and Li Hong found some traces.
Due to the rain last night, the construction site was slippery and muddy. The soles of the shoes would definitely be stuck with mud.
At the scene, there were two rows of clear footprints.
Chen Yan was watching carefully, and so was Li Hong.
To be able to become the captain of the city’s detective squad one, Li Hong was already an experienced detective.
“The footprints at the scene are a size 36 shoe and a size 37 shoe. They should be women’s shoes.”
Men and women had different body structures. Even if they had the same shoe size, the structure of their shoes would be different.
Therefore, based on the shoe prints, he could determine the gender.
“According to the scene investigation of the deceased this morning, the shoe print number 36 is the deceased’s.”
Chen Yan nodded. The mark was obvious and easy to determine.
Li Hong followed the two rows of footprints and walked to the side of the floor, which was directly above the crime scene.” Here, the victim s footprints are pointing toward the inside of the building. His back should be facing the outside.”
“If you fall from this angle … It just so happens that his back is on the ground.”
Li Hong frowned deeply, his mind spinning rapidly.”Could it be that the victim was pushed down from here?”
If that was the case, the case would be a little complicated.
According to the autopsy report, the fall injury was not fatal.
However, it would definitely have a great impact on the murderer’s escape.
Chen Yan shook his head.
Chen Yan pointed at the two rows of footprints.” Inspector Lee, look. The distance between the number 37 shoe print and the victim’s shoe print.”
Distance?
“Inspector Lee, you stand next to the other shoe print.” Chen Yan stood beside the deceased’s footprint.
Li Hong walked over and stood still.
“Inspector Lee, try pushing me.”
Hmm?
Li Hong was slightly stunned. He raised his arm tentatively, but put it down halfway.
” The distance between the two footprints is about 1.2 meters.” Chen Yan measured the distance between the footprints.” Even an adult man’s arm can’t reach her, let alone a woman wearing a size 37 shoe.”
“Could it be that the victim fell down on her own?”
Chen Yan shook his head. He didn’t know.
However, there was one thing that made Chen Yan a little vigilant.
Although the air was leaking from the upper floor, there was still some lingering smell.
This morning, Chen Yan opened the olfactory gene lock at the crime scene and found three relatively special smells.
One of them was nitrogen.
One of the other two was the scent of the deceased, and the other was the scent of the female detectives present.
But now, it seemed like that might not be the case.
On the second floor, Chen Yan found two smells. One was the smell of the deceased, and the other was a smell that was completely different from the scene of the crime in the morning!
The smell was limited to a certain area.
Even if the air was moving very fast, the smell would still stick to the nearby objects.
Therefore, the smell on the second floor could not be smelled downstairs, but it could be found at the scene.
In other words, last night, the victim had met a woman on the second floor. After falling off the building, there might be another woman at the scene?
“That’s not right either. There are only three scents downstairs. Nitrate, the scent of the deceased’s perfume, and another scent…”
“But…Why isn’t there a man’s scent?”
One had to know that the victim had been violated before she died.
Of course, it was unrealistic to rely solely on smell to solve the case.
Chen Yan could smell it because the smell gene lock was unlocked. Others couldn’t smell it.
Moreover, when Chen Yan passed by the scene downstairs, he realized that all the smells were already inaudible.
After a day, there were still some beams and buildings on the second floor, so there was a lingering smell.
By tomorrow, even Chen Yan would not be able to smell anything.
He returned to the station of Detective Squad One.
Chen Yan kept replaying the clues he found during the day in his mind, trying to infer all the clues together and restore the crime scene.
” Captain Chen.” Just as Chen Yan was thinking, Li Hong came in with a lunch box.”Come, have something to eat. We have a case to solve, so we have to eat.”
“Thank you, Inspector Lee!” Taking the lunch box from Li Hong, Chen Yan woke up from his thoughts. His stomach was rumbling as he smelled the fragrance of the rice.
Li Hong handed a pair of chopsticks to Chen Yan and smiled. “”Brother Chen, I’m a few years older than you, so I’ll call you brother.”
“Captain Li, look at what you’re saying!” “Brother, please don’t stand on ceremony with me.” Chen Yan quickly took the chopsticks.
“Alright, we re detectives. We’ve solved cases together, so we’re comrades.”
Li Hong, who also opened his lunch box, looked at the complicated lines and names on the case analysis panel.
Liu Jingting, Jia Xinyi, the unknown man, the unknown woman, and even Qin Xiaoyu’s roommate.
“Brother Chen, you don’t need to worry. Luan Ping and your men have been out for almost a day. When they come back, there will be more clues. Naturally, it will be easier.”
Chen Yan nodded. Of course, he knew what Li Hong meant.
However, Chen Yan was worried that this case would not be easy to solve.
Chen Yan believed in the system.
Ten days to solve the case.
At the very least, it would be more difficult than the case of dismembering his wife.
Bang!
As the two of them were chatting, the office door suddenly opened.
It turned out that Li Hong’s subordinate who had arranged for the DNA test had returned.
“Captain! Captain Chen!” Liang Xu looked excited as he pointed at the report in his hand. “”The comparison results are out!”
He came out?
So fast?
The DNA sequence comparison required blood samples for testing.
At this moment, the blood collection should have just ended, right?
They hadn’t even finished the DNA sequence yet, and there were already results so quickly?
” Why are you so fast? Tell me what happened!”
Hehe.
Li Hong’s subordinate, Liang Xu, chuckled and gulped down a mouthful of water. He panted heavily, “”In the afternoon, after the autopsy of the deceased was completed, 1 immediately compared the report results with the criminal gene bank.”
Li Hong and Chen Yan nodded. This was considered a routine operation.
“In the end, when my subordinate called me just now, he actually won!”
Li Hong snatched the comparison report from Liang Xu’s hands and read the results carefully.
“Zhang Jun?”
“Yes, it’s this Zhang Jun.” Liang Xu pointed at the photo on the file.* This guy is a repeat offender. He was released last year for theft.”
“Where is this person now?”
“I’m working part-time at the construction site of the Liancheng Institute of Art’s teaching building!”
Li Hong was overjoyed..” Then what are we waiting for? Catch them!”
