After the all-night struggle of an old interrogator in the bureau, in the face of the facts that could not be justified, Zhang Cailiang confessed.

At about half past seven in the evening on the day of the incident, Zhang Cailiang rode a motorcycle through the first scene.

At that time, an elderly man crossed the road with a large bundle of corn stalks, because Zhang Cailiang did not observe the old man in advance, and the motorcycle could not dodge and knocked the old man down.

The motorcycle also fell on the side of the road, causing damage to the small light on the right side, and Zhang Cailiang injured his right index finger.

Zhang Cailiang saw that the old man was seriously injured and saw that there was no one around, so he rode a motorcycle and left, but he didn't know that there was a drop of blood near the scene.

However, whether a vehicle subsequently ran over the deceased is uncertain from the current evidence.

About half an hour later, a fully staffed shuttle bus passed through the first scene, because there were a large number of corn stalks on the ground, the shuttle bus did not pay attention to the corpse on the road, so the body was stuck at the bottom of the bus, and fell at the second scene 15 kilometers away.

After Zhang Cailiang's description, the identity of the deceased was also clarified, he was a lonely homeless old man who hugged a cornstalk to make a fire......

The case is basically over here, and it is not the murder and throwing away the body as mentioned when the case is accepted, and the rest is to finish the work, sort out the file, and submit it to the procuratorate.

That night, after bringing Zhang Cailiang back to the bureau, the members of the task force were disbanded and went home.

Xiao Ran couldn't wait to return to the apartment, after all, in the three days at the police station, the time was tight and the task was heavy, non-stop during the day, and there was no time to take a shower at night, so he could sleep immediately by the bed.

So much so that Xiao Ran himself felt a bad smell on his body, went back to take a good hot bath, and slept beautifully - I hope that tonight is safe and there is no police.

Looking at Xiao Ran's departing figure, Qin Zihe silently cheered himself up in his heart, he must continue to work hard, strive to keep up with Xiao Ran's pace, and not be left behind!

Sleeping beautifully until he woke up naturally, Xiao Ran turned off the alarm clock, happy that last night was another Christmas Eve.

As soon as I was happy, I wanted to do something, so when Xiao Ran entered the forensic office with two hearty breakfasts, watching Yu Yu happily licking the caviar on the baked eggs, Xiao Ran smiled even more warmly.

"Nothing to do, either a traitor or a thief!"

Yu Yu felt more and more that there was a little devil hidden under the handsome and sunny skin of Xiao Ran, the kind that eats grapes and does not spit out the skin.

"No rape, no theft. ”

Xiao Ran shook his finger and said with a clear conscience: "I saw that you were busy so early, and you must have not eaten yet, so ......"

"Xiao Ran, you have changed. ”

Yu Yu's eyes were full of surprise: "You actually learned to coax a girl, you are no longer the cold-faced male god I know, your image in my heart has collapsed, woo woo ......"

Xiao Ran glared at Yu Yu: "Give you a good face and you will kick your nose, right...... It's been a few days since I got the cigarette butts I gave you before, and the DNA has been ready. ”

"I knew you weren't so kind!"

Yu Yu snorted, as if he had already seen through Xiao Ran, and threw Xiao Ran a USB flash drive: "The information is all in it, what do you want to do yourself...... By the way, this breakfast doesn't count, I'm going to have a big meal!"

"Got it. ”

Xiao Ran took the USB flash drive, knocked Yu Yu's little head, turned around and left.

As for having a meal or something, have you said it, what about human witnesses, is there such a thing?

Back in the office, open the USB flash drive given by Yu Yu, log in to the system and start comparing the DNA sequence.

Although I don't know why the Eye of Justice warned this cigarette butt at that time, since there is any suspicion, let's compare it.

After all, on this cigarette butt, it seems that only DNA may be left, if it is not to compare DNA, could it be that the Eye of Justice wants to tell Xiao Ran that it is a fake cigarette from the butt of this cigarette?

How could it be!

But if the comparison doesn't come up with any results, it's really hard to do.

Looking at the long DNA sequence in the USB flash drive, after looking at it for a long time, Xiao Ran suddenly felt a sense of déjà vu for this DNA.

Where have you seen it?

Xiao Ran knocked on his head, he had read too many files in the past few days, and suddenly he really couldn't remember.

Shaking his head, Xiao Ran didn't continue to entangle, anyway, the system was already comparing, if he had seen it a few days ago, then it would definitely be detected in the end.

After a short break in the morning, Xiao Ran opened the fingerprint library and looked at one fingerprint photo after another boredly.

In the morning, I followed Pang Jinghui to the Linqu District Bureau, merged the two theft cases into one case, and went to the procuratorate to hand over a file, and when I came back at noon, the system on the computer was still matching.

"Tick!"

Not long after Xiao Ran sat down, a prompt suddenly came from the computer in front of him.

Xiao Ran, who was lying on the table eating, raised his head for a moment, and then saw the system words 'Matched Successfully' on the computer screen.

Pushing the meal away, Xiao Ran quickly clicked on the file of successful matching.

"The ...... of the 721 Murder Case"

The moment the electronic file was opened, Xiao Ran's heart seemed to stop beating, and his deep eyes were filled with words on the screen.

"The murderer has not been found so far, an unsolved case from eight years ago!"

Xiao Ran read through the file and felt that sweat was oozing slightly from his palms.

It is written in the file that on July 21, eight years ago, the H City Public Security Bureau received a report from the masses that a life case occurred in a certain community.

After receiving the police information, the police of the Public Security Bureau quickly dispatched and arrived at the scene, and the police found that the deceased was a young woman named Cheng Ying, 25 or 6 years old, with scars on her body and neck.

After a forensic autopsy, it was determined that the deceased had died of mechanical asphyxiation caused by someone holding him around the neck, and that the wounds on the deceased's body had been formed before death.

The medical examiner then found white viscous genetic material in the deceased's lower body and suspected skin debris in the deceased's fingernails, and after comparison, the medical examiner determined that the genetic material and the debris were from the same person.

So the police judged that this should be a murder incident after forcible annihilation, a criminal case of an extremely bad nature!

However, when the police investigated the scene, they found that the scene had been cleaned by the criminals extremely carefully, and everything was neatly arranged, except for the genetic material in the deceased's body, no trace was left.

The police started from the aspect of genetic material, and constantly compared with all the men around Cheng Ying who had dealings, but found nothing.

In the end, after more than two years of hard work, the police reluctantly put the case on hold temporarily, leaving only a copy of DNA information, which was occasionally brought up for comparison in the information database.

This case has also become an unsolved case in the hearts of the police officers in H City......

And now, the same DNA sequence as the case at that time actually appeared on a cigarette butt!
