Chapter 1057 Determining the Ownership of the Garbage Bag
In addition to some of the contents of the investigation that have been determined so far, other members of the serious crime team also separately investigated the interpersonal relationships of the victims related to previous internship cases and the victims of this case. Compare the interpersonal relationships.
It’s just that the amount of data is relatively large, so we haven’t found much yet.
At present, some related personnel have been found, and there is relatively clear evidence of alibi outside of the investigation. The current investigation in this area 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 crime team.
In fact, it is still not completely certain whether this is possible. It is only used as an investigation direction.
After reporting on several aspects, Li Donglin looked at Lu Chuan.
"Lu Chuan, let's see if you find anything here first?"
This time, Li Donglin actually didn't have much hope in seeing this.
Li Donglin has read the autopsy report. In fact, Li Donglin has studied the files many times, including the files of previous cases.
The killer in red seems to be very good at making some confusing moves.
Although some of the 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. There is no reason why he would leave his own evidence for the 11th time.
What is certain now is that the other party only left experiences and his own DNA information in the bodies of these victims.
In addition, it seems that all the evidence left at the crime scene is false, and they are smoke bombs used by the murderer to interfere with the police's investigation.
Of course, although Li Donglin has this judgment, in fact, as a technical criminal policeman with a background as a detective, he hopes that the criminal suspect can be identified through technical means.
Because this is the ironclad proof.
Lu Chuan didn't get a good night's sleep in the past few days, and he only had about three or four hours of rest every day.
However, the gains on his side are still great.
“I have some discoveries here.”
Lu Chuan stood up, turned on the projection, and began to report some details he had discovered.
“First, I extracted some broken fingerprints from the black plastic bag.”
The projection shows the black plastic containing the victim’s severed finger found in the trash can at North Lane 2, Jianguo Road. Bag photo.
Everyone is familiar with this photo. Li Donglin has even seen it dozens of times.
"Comparison successful?"
Li Donglin is a technical criminal police officer. He used to compare fingerprints. Of course, he knows very well how difficult it is to pick up fingerprints on such a black medicine bag, and if the comparison is to be successful, the workload involved is unreasonable. calculated.
Lu Chuan nodded affirmatively.
"The comparison was finally successful this morning."
The processing of these broken fingerprints took more time than I had imagined.
The fingerprints were too broken. It took Lu Chuan nearly two days to finally piece together the lines of these broken fingerprints based on 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, 2/3 fingerprints were obtained, and compared in the system The owner of the fingerprint was found!”
Lu Chuan flipped the projection.
A middle-aged man appeared on the screen.
"Huh? Is it him?"
Before Lu Chuan could tell the identity of this person, Wang Song suddenly stood up. "How could it be him?"
Li Donglin felt moved when he saw Wang Song's reaction.
Lu Chuan's side is doing purely technical analysis work, while Wang Song's side is mainly responsible for investigating the victim's interpersonal relationship.
If there is any intersection between these two, then...
Li Donglin’s heartbeat suddenly accelerated!
Lu Chuan was not surprised.
When he successfully compared this person, his identity was confirmed.
“Yes, this person’s name is Gao Zhiyuan, and he is a purchasing employee at Aijia Supermarket.”
The broken fingerprints Lu Chuan found on the black plastic bag belonged to a person named Gao Zhiyuan , and this person’s workplace is in Aijia Supermarket, and the victim Zhu Panpan is in a supermarket. It is very likely that there are work contacts and contacts between them.
The black plastic bag containing the victim’s severed finger was found to have his colleague’s fingerprints on it. What does this mean?
"But...it's impossible. I have an impression of this person."
Wang Song investigated the staff in Aijia Supermarket one by one, so although this Gao Zhiyuan is just a purchasing employee , but Wang Song remembered it as soon as he saw the other party's photo.
“Although this person knew the victim, he was not particularly familiar with him. He was in charge of material procurement at the back and had little connection with the front desk. The two of them just knew each other’s names.”
"The most important thing is that the other party went on a business trip on the morning of the first day of the Lunar New Year and came back on the sixth day of the Lunar New Year. He was not in Dongzhou City at all!"
When everyone heard this, they were involuntarily stunned.
I don’t know what to do, this scene seems familiar at all, this case seems to be the same as the previous cases.
Fingerprints were found at the crime scene, but the owners of these fingerprints had alibi.
What is different from the previous cases is that this time the fingerprints deliberately left by the murderer on the black plastic bag were difficult to successfully compare due to the carrier.
“The murderer left it on purpose?”
“Grass!”
upset.
The other party seems to be doing this intentionally. Is he mocking the police handling the case?
"Li Chu, in addition to this, there are some other discoveries about the black plastic bag."
Lu Chuan worked hard for three or four days, and found more than just a fingerprint. He has many other clues.
“Let’s put this person named Gao Zhiyuan aside for now.”
A photo that appeared under Lu Chuan's projection showed the residue of some tea leaves.
"This is..."
Seeing the thing in the photo, everyone knows that it is tea residue, but what does this have to do with solving the case?
“Is this the tea leaves in the plastic bag?”
Li Donglin carefully looked at the contents of the black plastic bag. In addition to the broken paper, there were also some residues of tea leaves and some Toilet paper and other scraps of trash.
Lu Chuan nodded: "This is indeed the tea residue in the black plastic bag."
"But this is not an ordinary tea residue."
Lu Chuan continued to operate, and what appeared under the projection was a Tea packaging box.
“This tea category is a big red envelope, but it is not an ordinary big red envelope. Judging from the tea residue, it belongs to a relatively expensive big red envelope category. I did some research and found that this kind of tea is probably the most expensive. Two will cost more than 10,000 yuan.”
“Obviously, Gao Zhiyuan... probably can’t afford this tea, right?”
