As he spoke, Tang Ze was checking around the sand pit, trying to see if he could find anything else.
He didn't have any expectations at first, but he didn't expect to pull out a key not far from the murder weapon.
"This looks like a locker key." Tang Ze looked at the key and pondered: "Who left it here? Or did the deceased drop it when he was attacked..."
"But it doesn't look like the key to the gym locker."
Nanatsuki Koshimizu took the key and said, "Anyway, we'll find out after a little investigation. Leave it to me. I should be able to find out which cabinet this key corresponds to by investigating the manufacturer."
"Also, collect some sand." Tang Ze called a forensic examiner over and instructed, "Remember to compare it with the sand on the soles of the deceased's shoes."
After everything was arranged, Tang Ze stood up and looked around, but found no trace of Dahlia.
Obviously, the dahlia pollen on the deceased must have been picked up from somewhere else.
All in all, the discovery of the park as the crime scene was a major breakthrough, and scientific research was naturally busy again.
The collected fingerprints, bloodstains on the stones, the composition of the sand, each piece of evidence was analyzed one by one.
And the test results came out soon.
First of all, there was bloodstains on the stone, which had been confirmed to be the blood of the deceased.
The wound on the victim's head was also confirmed to be in the same shape as the stone after comparison.
It is almost certain that this stone caused the wound.
In addition, they also detected fingerprints on the stone, which were most likely the murderer's fingerprints.
However, after comparing the database of criminals with previous convictions, no one with the same fingerprint was found in the fingerprint database.
In addition, gravel from the Qinming Coast, dahlia pollen, tree roots, and cat and dog hair were found in the soil extracted from the park.
Some of the cat hair was consistent with the cat hair extracted from the victim.
In other words, their previous speculation was correct, and the gravel on Qinming Coast was actually the sand that was moved to the sand pit in the small park.
"The only pollen whose source hasn't been found is dahlia pollen."
After reading the report, Nanatsuki Koshimizu said, "But there's dahlia pollen in the sand pit, which proves that there were indeed dahlias in the park."
"Maybe someone bought a bouquet of dahlias and passed by the park and left some pollen."
Tang Ze touched his chin and speculated, "Anyway, Dahlia once existed here.
By the way, did you find anything over there?"
"I came here just to tell you this. We've found the source of the key." Nanatsuki scratched his head and sighed, "The key in the bunker belongs to a public locker. When we opened it, we found a handbag inside.
But after opening it, I found all kinds of miscellaneous items inside.
Clothes, bags, speakers...
There are a lot of messy things and there is no system at all.
And if you look closely, some of the things are quite worn out, and you can't tell what they are used for.
I have asked the laboratory to investigate, and the results will be out soon."
"Then wait patiently for a while."
After hearing this, Tang Ze nodded, and began to look forward to the items that Koshimizu Nanatsuki had found.
Although everything is going smoothly in the investigation now, not only has the crime scene been found, but the murder weapon and the suspect's fingerprints have also been basically found.
However, these clues did not allow them to go further.
None of the clues pointed to the identity of the deceased, and without a way to confirm the identity, there was no way to check the interpersonal relationships.
That's why Tang Ze hopes that the items in this locker can help them find some clues and discover the identity of the deceased.
Otherwise, relying solely on the clue of the tooth, they didn't know how long they would have to wait.
Even if the tooth was very expensive at the time, if a nationwide investigation was carried out, it would take a lot of time just to check one region at a time.
Therefore, it is best to further investigate the other party's intelligence.
Even common information like where the other party is from can save them a lot of investigation.
However, as the identification results of an item came out, the two people's hearts, which had originally been filled with hope, gradually sank.
Because these things were so mixed and some were damaged, they looked like they were picked up, which made Tang Ze think that the other party was a homeless person again.
As the results of each item came out, it seemed to further verify Tang Ze's idea.
Those items were stained with fingerprints of different people, and their identities could not be found.
"What are these?"
Looking at the inspection data of the numerous items, Nanatsuki Koshimizu said somewhat dejectedly, "It's such a mess, it feels like I just picked it up."
"Well, it's not like there's no gain."
Just as he turned to the identification report of one of the items, Tang Ze suddenly stopped turning the pages and looked at one of the documents carefully.
"Is this a blanket?"
Nanatsuki Koshimizu came over to look at the information and said, "There is hair from the deceased on it. It looks like it belongs to him.
But there shouldn't be anything noteworthy about this, right?"
"Look at the composition of the blanket." Tang Ze smiled and pointed to one of the results in the report: "It contains Volvox and diatoms, which are microorganisms found in rivers."
"But that only means the deceased used this blanket near the river," Nanatsuki Koshimizu said, puzzled. "Maybe they had a picnic or something."
