On The Day Of My 100th Blind Date, I Arrested My Date

Now that the results of the autopsy examination have come out, the next step is to arrange the deployment, investigation and arrest.

There are no fingerprints left on the neck of the deceased, so comparing the residual body fluids in the deceased is the only method at present.

"Li team," Chen Yan looked at Li Hong: "The next step is to find people who match the DNA sequence of the deceased's body fluids."

"Well, I'll arrange this!"

Chen Yan nodded: "The point is that the construction workers on the construction site can be screened in the name of blood collection and physical examination."

Of course Li Hong knew what Chen Yan meant.

Last night, only the workers lived at the construction site, and it was unlikely that students would go there.

"Also, let's go to the scene now and check the floor where the deceased fell.

In the morning, although Chen Yan found that the deceased had crawling marks, the ground was slippery and muddy due to the rain, and the deceased did not leave any traces of falling on the ground.

……

The scene is still blocked.

The newly renovated teaching building has a total of six floors and has now become a framework.

The inside of the building is relatively empty, and there is ventilation everywhere.

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, and the soles of the shoes would definitely stick to mud.

At the scene, there are two rows of footprints, very clear.

Chen Yan was watching carefully, and Li Hong was also watching.

To be the captain of the Liancheng Detective Unit 1, Li Hong is also an old detective.

"The footprints at the scene, one is a shoe of size 36 and the other is a shoe of size 37. They should all be women's shoes."

The body structure of men and women is different, even the same shoe size, the structure of the shoes is also different.

So according to the shoe print, the gender can be determined.

"According to the investigation of the deceased at the scene in the morning, the shoe print No. 36 belongs to the deceased."

Chen Yan nodded, the mark was obvious and it was easy to judge.

Li Hong followed the two rows of footprints and walked to the edge of the floor, which is directly above the crime scene: "Here, the toes of the deceased's footprints are facing the inside of the building, and their backs should be facing the outside."

"If you fall from this angle...it happens to be on your back."

Li Hong's brows were deeply wrinkled, and his mind was racing: "Could it be that the deceased was pushed down from here?"

If that were the case, the case would be a bit more complicated.

Although according to the autopsy report, the fall injury is not fatal.

However, it will definitely have a great impact on the escape of the murderer that the deceased faces next.

Chen Yan on the side shook his head.

Chen Yan pointed to the two rows of footprints: "Captain Li, look, the distance between this number 37 shoe print and the deceased's shoe print."

distance?

Chen Yan stood beside the footprints of the deceased: "Captain Li, you are standing beside another shoe print."

Li Hong walked over and stood still.

"Team Li, try to push me."

Um?

Li Hong was slightly taken aback, raised his arm tentatively, but lowered it halfway.

"The distance between the two footprints is about one meter two," Chen Yan gestured the distance between the footprints: "Even an adult male's arms can't reach each other, let alone a woman wearing size 37 women's shoes?"

"Could it be that the deceased fell by himself?"

Chen Yan shook his head, he didn't know this.

However, there is one thing that makes Chen Yan a little bit alert.

Upstairs, although there is air leaking everywhere, there is still a little smell left.

This morning, Chen Yan turned on the olfactory gene lock at the crime scene and discovered three relatively special smells.

One of them is nitroglycerin.

The other two, one of which was the scent of the deceased, and the other, which Chen Yan also believed might be the scent of the female detective present.

However, now it seems that it is not necessarily so.

On the second floor, Chen Yan found two kinds of smells, one was the smell of the deceased, and the other was a different smell from the crime scene in the morning!

There are certain regional restrictions on the residual smell.

Even if the air is moving fast, the smell will still stick to nearby objects.

All, the smell of the second floor, which you can't smell downstairs, can be found at the scene.

That is to say, last night, the deceased once met a woman on the second floor. After falling from the building, might another woman appear at the scene?

"That's not right, there are only three scents downstairs, nitroglycerin, the perfume of the dead, and another scent..."

"But...why doesn't it smell like a man?"

You know, the deceased was violated before he died.

Of course, it is unrealistic to rely solely on smell to decide a case.

Chen Yan can smell it because the olfactory gene lock is turned on, and others can't smell these odors.

Moreover, when Chen Yan passed by the scene downstairs just now, he found that all the smells were indistinguishable.

After a day's time, there are still some beams and buildings on the second floor, so the smell remains.

Until tomorrow, even Chen Yan won't be able to smell anything.

Return to the station of the Detective Unit 1.

Chen Yan kept reviewing the clues he found during the day in his mind, trying to reason all the clues together and restore the crime scene.

"Team Chen," while Chen Yan was thinking, Li Hong walked in with a boxed lunch: "Come on, have something to eat, the case is going to be handled, and the meal should be eaten."

"Thank you, Team Li!" Taking the lunch box that Li Hong handed over, Chen Yan woke up from his thoughts. He smelled the smell of the rice and his stomach was rumbling.

Handing a pair of chopsticks to Chen Yan, Li Hong smiled: "Brother Chen, I'm a few years older than you, so I will call you brother."

"Captain Li, see what you said!" Chen Yanliang quickly took the chopsticks: "Brother, please don't be polite to me."

"Okay, we are detectives and we have solved cases together, so we are comrades-in-arms."

Li Hong, who also opened the lunch box, looked at the complicated lines and names on the case analysis panel.

Liu Jingting, Jia Xinyi, unknown men, unknown women, and even Qin Xiaoyu's roommate.

"Brother Chen, you don't have to worry, Luan Ping and your subordinates have been out for almost a day~www.wuxiamtl.com~ When you come back, there are more clues, so it will be easy to handle."

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.

Otherwise, Chen Yan still believes in the system.

The seven-day detection period.

At least it's more difficult than the case of dismembering a corpse and killing a wife?

boom!

The two were chatting when the office door was suddenly opened.

It turned out that Li Hong's subordinate who arranged for the DNA investigation came back.

"Captain! Team Chen!" Liang Xu was excited, pointing to the report in his hand: "The comparison result is out!"

Out?

So fast?

DNA sequence alignment requires blood testing.

At this moment, the blood collection should have just ended, right?

The DNA sequencing has not been completed yet, so the result will be obtained so soon?

"Why so fast, tell me what's going on!"

hey-hey.

Li Hong's subordinate, Liang Xu hehe smiled, took a sip of water, and gasped: "In the afternoon, after the autopsy of the deceased, I immediately compared the report results in the criminal gene bank. ."

Li Hong and Chen Yan nodded, this was a routine operation.

"As a result, my subordinate called me just now, and it was compared!"

Li Hong snatched the comparison report from Liang Xu's hand and carefully looked at the results above.

"Zhang Jun?"

"Yes, this is Zhang Jun." Liang Xu pointed to the photo on the file: "This guy is a repeat offender, and he was just released last year for theft."

"Where is this person now?"

"Just doing odd jobs on the construction site of the teaching building of Liancheng Art College!"

Li Hong's face was overjoyed: "Then what are you waiting for, catch it!"
