But in addition to this, there is another person's fingerprint, but his identity information is unknown.
However, this fingerprint is most likely the murderer's, because after comparing the fingerprints, it was found that the fingerprint is consistent with the fingerprint on the murder weapon.
So it can be basically confirmed that the murderer had touched the envelope.
This seems meaningless, but in fact it points out another direction of investigation for Tang Ze and others.
That was the cause of the murder, most likely a robbery.
As for the skin fragments they finally found on the cat's paw, they were confirmed to be human.
However, after comparison, they found that it was not Morikawa Kazuhiro's, which means it was most likely the murderer's.
After careful testing, they discovered a tea-colored coloration.
After further analysis of the tea color, it was found that its components include salt, amino acids, nucleic acids and other substances.
After comparison, it was found that the ingredient was fish sauce, which is made by fermenting fish.
In addition to this, there are other substances, and after comparing the ingredients, it was found to be mango juice.
When Tang Ze heard the combination of these two things, a flash of inspiration came to his mind and a figure flashed through his mind.
At this moment, Nanatsuki Koshimizu also looked over, with the same expression on her face as Karasawa.
Obviously, after receiving the news, both of them thought of the same person.
The waiter who was very dissatisfied with Mr. Kazuhiro Morikawa, the "try-only" man.
Among his tasting dishes, there are many pickles, including mango slices with fish sauce.
And the other party has sufficient motives to commit the crime.
After knowing this, Tang Ze immediately contacted Takagi, described the other party's appearance, and asked him to go to the underground supermarket to have a meal and obtain the other party's fingerprints.
After all, everything is just speculation now. If Tang Ze and the other person go over to collect fingerprints, and there is no way to arrest the other party immediately, it might alert the other party and give him a chance to escape again.
So in order to avoid this, it is natural to send someone the other party does not know to secretly collect fingerprints.
After Takagi arrived at the restaurant, he secretly took a photo at the door and sent it to Tang Ze. After confirming the person, he went in and ordered food.
He kept the packaging of the disposable chopsticks that the other party had given him, and put away the disposable paper towels that had also been given to him, and then began to enjoy his dinner.
However, Takagi ate the meal quickly, and then sent the two pieces of evidence wrapped in a handkerchief to the scientific research institute.
The next step was to extract and compare fingerprints. Because this was the final step, no one wanted to go home. Tang Ze and others went to the cafeteria to deal with it for a while, and then came back to get the results.
The waiter's fingerprints matched those on the murder weapon and the envelope.
Without any hesitation, after getting this result, Takagi and Sato Miwako immediately arrested the waiter named Akiyoshi Seta.
By the way, when arresting the other party, Takagi also saw cat scratches on the other party's arm, which also proved that the other party was the murderer.
According to the other party's explanation, he was very angry because Mr. Morikawa Kazuhiro, the "try-only" man, often came to their house to eat and drink for free.
That day, he went home early because of something and happened to see him coming out of the pawnshop, so he had bad intentions.
Because he often came to try the food, everyone knew more or less about his situation. Some people also said that they saw him with homeless people, so the rumor was probably that he was a homeless person.
For such people at the bottom of society, Akiyoshi Seta naturally had no fear of bullying them.
Evil thoughts suddenly took over his mind and he followed Morikawa Kazuhiro directly.
When they followed the other person all the way to the children's park, seeing that there was no one around, Akiyoshi Seta suddenly put his arms around the other person's neck from behind and blackmailed him by asking him to pay some food expenses since he had been eating and drinking for free for so long.
Morikawa Kazuhiro naturally didn't want to do that, and the two fell into the sand pit while fighting. He picked up a stone and hit the other person on the head.
The already older Kazuhiro Morikawa was now at a disadvantage and could only tightly protect the envelope on his chest.
At this moment, a cat suddenly ran over and scratched his arm. The pain made him subconsciously let go of his hand to check the situation.
Taking advantage of this opportunity, Morikawa Kazuhiro quickly got up and ran away.
Akiyoshi Seta thought he had just failed in a robbery, but he didn't know that the casual smash he made would lead to the death of Kazuhiro Morikawa.
When he was caught, he was still a little bit unbelievable why the other party died like this.
But everyone must be responsible for his own actions, and if he could be more open-minded, or not understand evil thoughts, such a tragedy would not have happened.
"Mr. Morikawa, please think about giving the money to Xiaohui no matter what."
After listening to the interrogation, Nanatsuki Koshimizu couldn't help but sigh, "Father's love is so heavy..."
Just as the two were walking towards the exit, a phone call suddenly came in. After Tang Ze answered it, he found that the call was from the gym where the crime scene was located.
The reason the other party called was because "Nobuo Takayama" left their gym's phone number to a jewelry store, saying that the item he had ordered was ready.
Hearing this, Tang Ze was so surprised that he wrote down the location of the jewelry store. After thanking him, he hung up the phone.
"He actually ordered jewelry?"
After learning the content of the call from Karasawa, Nanatsuki Koshimizu said in surprise, "This Mr. Morikawa is really smart.
