Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 1057 Determining the Ownership of the Garbage Bag

In addition to some of the content that has been determined to be investigated, other people in the serious crime team also compared the interpersonal relationships of the victims related to previous internship cases with the interpersonal relationships of the victims in this case.

It’s just that the amount of data is quite large, and there haven’t been any significant discoveries yet.

At present, some related persons have been found and their investigations have shown relatively clear evidence of their alibi. However, the investigation in this regard has not made much substantial progress.

In addition, the possibility that the victim and the murderer are related or know each other is just a speculation made by the serious crime team.

In fact, whether this is possible is still not completely certain at present, it is just a direction of investigation.

After reporting on several aspects, Li Donglin looked at Lu Chuan.

"Lu Chuan, have you found anything here?"

In fact, Li Donglin didn't have much hope for this aspect this time.

Li Donglin has read the autopsy report. In fact, Li Donglin has studied the case files many times, including the files of previous cases.

This killer in red seems to be very good at doing confusing moves.

Although some fingerprints and footprints he left at the crime scene pointed to certain people, none of them were suspects.

The other party has done this ten times before, so there is no reason for him to leave evidence for the 11th time.

What is certain now is that the other party only left experiences in the bodies of these victims and left their own DNA information.

In addition, it seems that all the evidence left at the crime scene is fake, and is a smokescreen used by the murderer to interfere with the police investigation.

Of course, although Li Donglin has this judgment, in fact, as a technical criminal policeman who came from the field investigation criminal police, he hopes that the field investigation side can use technical means to lock in the suspect.

Because this is irrefutable evidence.

Lu Chuan hasn't had a good night's sleep in the past few days, and he only has about three or four hours of rest every day.

However, he still gained a lot.

"I have some discoveries here."

Lu Chuan stood up, turned on the projector, and began to report some details he had discovered.

"First, I extracted some residual fingerprints from the black plastic bag."

The projection shows a photo of a black plastic bag containing the victim’s severed fingers that was found in a trash can in North Lane 2, Jianguo Road.

Everyone is familiar with this photo, and Li Donglin has even seen it dozens of times.

"Did the comparison succeed?"

Li Donglin was a technical criminal policeman. He originally matched fingerprints. He knew very well how difficult it was to find fingerprints on this kind of black medicine bag. And if he wanted to make a successful match, the workload would be incalculable.

Lu Chuan nodded affirmatively.

"We finally succeeded in matching them this morning."

The processing of these broken fingerprints takes more time than expected.

The fingerprints were too broken, and Lu Chuan spent nearly two days before he finally pieced together the patterns of the broken fingerprints according to his experience, but he only managed to piece together 2/3 of the fingerprints.

"No fingerprint residue was found on the surface of the black plastic bag, but some broken fingerprints were found on the handle of the black plastic bag. After splicing and extracting these fingerprints, we got 2/3 fingerprints and compared the fingerprint owner in the system!"

Lu Chuan flipped the projection.

A middle-aged man appeared on the screen.

"Huh? Is it him?"

Before Lu Chuan could reveal the identity of this person, Wang Song suddenly stood up. "How could it be him?"

Li Donglin was moved when he saw Wang Song's reaction.

Lu Chuan's job was purely technical analysis, while Wang Song's was mainly responsible for investigating the victim's interpersonal relationships.

If these two intersect, then...

Li Donglin's heartbeat suddenly accelerated!
Lu Chuan was not surprised.

When he successfully matched this person, his identity was confirmed.

"Yes, this person is called Gao Zhiyuan, and he is a purchasing employee at Aijia Supermarket."

The broken fingerprints that Lu Chuan found on the black plastic bag belonged to a man named Gao Zhiyuan, who worked in the same Aijia Supermarket as the victim Zhu Panpan. It is very likely that they had some work-related interactions.

The victim’s colleague’s fingerprints were found on the black plastic bag containing his severed fingers. What does this indicate?
"But...that's impossible. I have an impression of this person."

Wang Song investigated the staff members in Aijia Supermarket one by one, so even though Gao Zhiyuan was just a purchasing employee, Wang Song remembered him as soon as he saw his photo.

"Although this person knew the victim, they were not particularly familiar with each other. He was in charge of purchasing materials at the back and had little to do with the front desk. The two people only knew each other's names."

"The most important thing is that the other party went on a business trip to purchase goods on the morning of the first day of the Lunar New Year and did not return until the sixth day. He was not in Dongzhou City at all!"

When everyone heard this, they were stunned involuntarily.

I don’t know what to do. This scene seems so familiar. This case seems to be the same as the previous cases.

Fingerprints were found at the crime scene, but the owners of those fingerprints had alibis.

What is different from the previous cases is that this time the fingerprints that the murderer deliberately left on the black plastic bag are difficult to match successfully because of the carrier.

"The murderer left it there on purpose?"

"Grass!"

upset.

The other party seemed to be doing this intentionally. Was he mocking the police officers handling the case?
"Director Li, in addition to this, there are some other discoveries about the black plastic bag."

Lu Chuan worked for three or four days and found not only a fingerprint, but also many other clues.

"Let's put this man named Gao Zhiyuan aside for now."

The photo that appeared under the projection operated by Lu Chuan was some tea residue.

"This is……"

When seeing the things in the photo, everyone knows that these are tea residues, but what does this have to do with solving the case?

"Is this the tea in the plastic bag?"

Li Donglin carefully looked at the contents of the black plastic bag. In addition to broken paper, there were also some tea leaves, some toilet paper, and other scraps of garbage and kitchen debris.

Lu Chuan nodded: "This is indeed the tea residue in the black plastic bag."

"But this is no ordinary tea residue."

Lu Chuan continued the operation, and a tea box appeared under the projection.

"This tea is Da Hong Pao, but this is not an ordinary Da Hong Pao. Judging from the tea residue, it is a relatively expensive Da Hong Pao. I did some research and found that one tael of this tea costs more than 1 yuan."

"Obviously, Gao Zhiyuan... probably can't afford this tea, right?"
