Ito finally looked up, knowing that if she didn't speak again, the situation would be even more unfavorable for her.

She tried hard to control her emotions and asked in a cold voice, "Officers, although I am only a housewife, I also know the truth of catching thieves and taking stolen goods. You've said so much, it's good and wonderful, but what about the evidence?"

Lin Lei walked up to Ito Chengjia and stared at her for a long time, before he said slowly: "Do you think that since I have concluded that you are the murderer, I will not find evidence?"

Ito Chengjia snorted coldly: "Hmph!"

All the policemen at the scene raised their hearts to their throats, and everyone knew that the most important thing - that must be evidence, not reasoning.

Lin Lei's previous reasoning was indeed reasonable and could be said to be wonderful, but without evidence, everything was in vain.

Lin Lei turned his head to the Fujimoto police station and said, "Fujimoto police officer, do you remember what I said just now that Ito Chengjia resigned from his job, which is very abnormal?"

Fujimoto nodded and replied, "Exactly." Ito Chengjia was in a hurry to find a job, but a good job was in front of her, and she quit it, which really didn't make sense. ”

"The reason is not complicated. Lin Lei's eyes deepened, and he said word by word: "It is human nature to seek advantages and avoid disadvantages." Ito must have been worried about her resignation from her job - her employer had no contact with her before, so the possibility that the employer had anything to do with the case could be ruled out. There are not many answers left, and the focus is naturally on the whereabouts of Ito Chengjia on the day of the crime. After the killing, she went back to her room in a panic, cleaned the blood stains briefly, and then went directly to the employer's house to apply for the job, without stopping elsewhere......"

Everyone was still thinking about various possibilities, but Lin Lei said directly: "There is only one truth. ”

While speaking, Lin Lei took out his phone and sent a text message.

Fujimoto asked, "Detective Lin, what's the truth?"

Lin Lei put the phone in his pocket and looked at Ito Chengjia: "You quit your job because you don't want the police to investigate you at your employer's house." If the police run to your employer's house twice in three days, you're afraid you won't be able to sleep at night......"

"Could it be that what evidence was left by Ito Chengjia at the employer's house?" Ono was the first to react and blurted out.

Lin Lei smiled but did not answer.

At this moment, the door of the apartment opened with a "squeak-" sound, and Qiao Yan and Lu Yun, who had never appeared, walked in.

Lin Lei pointed at Qiao Yan and said to Ono Police: "What you want most, naturally you have to find a forensic doctor to ...... it."

The "most wanted thing" in Lin Lei's mouth is well known to everyone, of course, it is evidence!

Without evidence, what is the use of reasoning?

At this time, Qiao Yan opened the forensic toolbox she was carrying, and took out a evidence bag from it, and inside the evidence bag, there was a doorbell!

That's right, it's the doorbell of Mr. Suzuki, Ito's employer!

Qiao Yan took a deep breath and said slowly: "After Ito Chengjia finished killing people, she went to Mr. Suzuki's house to apply for a job in a very short period of time, which shows that she didn't dare to change her clothes rashly, and there was not enough time to wash the bloodstains. From going home to killing people and then going out, it only took about ten minutes for Ito Chengjia, so it was a high probability event that she went to Mr. Suzuki's house with some biological information. ”

Everyone's eyes focused on the transparent evidence bag in Qiao Yan's hand, of course, the focus was on the doorbell in the evidence bag.

Fujimoto looked at the doorbell carefully, but did not find any obvious traces, Ono also walked up to Qiao Yan, and after asking for permission, he carefully took the evidence bag and examined it carefully.

However, after reading it, Ono had a suspicious expression on his face: "This ......"

Ono was a little afraid to say it, but Fujimoto asked in a low voice, "Forensic Doctor Joe, I feel like this is an ordinary doorbell!"

Qiao Yan smiled slightly and explained: "Edmund Rocca, the father of forensics, once said a famous saying - whoever walks must leave traces. There is a basic principle in micro-testing: every contact leaves a trace, even if it is very subtle. This is because all molecules are not stationary, and the thermal movement of the molecules will definitely leave some particles in the contact object when they are in contact, as for whether they can be detected, it depends on the level of the instruments used and the detectors. ”

After leaving his employer, Mr. Suzuki's house, that day, Lin Lei quickly locked up the real culprit - Ito Chengjia.

The key is not how to reason, but how to lock down the evidence.

After Ito Chengjia killed someone, he simply dealt with the blood stains and hurried to the employer's house for an interview, so it is a high probability that some biological traces were left at Mr. Suzuki's house.

What is even more corroborative is that Ito Nariyoshi was initially reluctant to go to Mr. Suzuki's house to investigate, and she quit her much-needed job. However, as soon as the news passed, Ito immediately returned to work at her employer's house - presumably she must have used the cover of work to carefully clean up all the things she had touched that day.

Except—the doorbell outside the door.

To enter the door, it is necessary to ring the doorbell, and the doorbell is outside the house and is not easy to attract attention.

Lin Lei's task for Qiao Yan is to carefully investigate Mr. Suzuki's house, and if no evidence can be found at home, then the doorbell must be carefully checked......

Qiao Yan took out an appraisal book, pointed to the relevant content and said to everyone: "Through the high-powered microscope, I found the sweat residue of Ito Chengjia on the doorbell. And in these sweat residues, the DNA composition of the deceased was detected. To be on the safe side, I did another time test, and finally locked the time of DNA residue on the day of the crime. In other words, on the same day, Ito Narika had the DNA of the deceased on his hand and rang the doorbell of Mr. Suzuki's house......"

Fujimoto suddenly realized, and said loudly: "Shuffle——! so that's the case!! no wonder Forensic Doctor Qiao and Officer Lu haven't seen anyone for a few days, it turns out that they are doing a DNA test!"

Ono Police also showed a convincing expression, and exclaimed: "It is worthy of Detective Lin, not only has a strict reasoning, but also a mountain of ironclad evidence, admire, admire!"

Lin Lei smiled slightly, didn't seem to care, just said lightly: "It's over." It's just a small CASE, and it doesn't bother me. ”

Yes, reasoning is important, but without evidence, reasoning bullshit is not!

Detective Lin not only reasoned, but also mastered the evidence, and the suspect could not refute it at all!

Everyone was amazed, and the atmosphere of the scene became lively for a while......

"No way! You're talking nonsense! I've wiped the doorbell many times!" Ito couldn't hold back anymore and yelled hysterically.

Lin Lei's eyes flashed, and he quickly returned to normal, and said nonchalantly: "What science do you know as a housewife? Do you know what forensic forensics is?

Ito argued loudly: "I didn't pay attention to the blood stains on the corner of my coat that day, and I found out when I got home later that I had cleaned all the places where I sat and touched the Suzuki family, and even the doorbell I wiped ......."

When these words were spoken, the faces of Lin Lei, Qiao Yan and Lu Yun all showed imperceptible smiles.

Fujimoto, who had been observing his words, widened his eyes, as if he realized something, but how could he dare to say it before Lin Lei didn't speak?

Lin Lei didn't have the slightest intention of "exposing" everything, but just said coldly: "Leave these words to the judge!"

Ito Chengjia's feet were weak, and she sat on the ground, trembling all over her body - her psychological defense line completely collapsed.

Lin Lei waved his hand, and Ono immediately ordered his subordinate policemen loudly: "Take her away!"

Soon, the police took Ito out of the apartment.

Fujimoto didn't leave, his mouth wide open and he couldn't close it all the time......

Everyone left, but Takashima didn't dare to leave - after all, he committed perjury and was a crime.

And at the same time, there is also Ryoko Hirota.

At this moment, Takashima Moto didn't bring his scarf either, and Miss Ryoko didn't seem to care, although both of them lowered their heads, there were some things that a discerning person could know at a glance.

Lin Lei glanced at the two of them, and said slowly: "Takashima, if you do something wrong, you have to take responsibility yourself......

Takashima Motoya nodded and replied in a deep voice, "I understand, Detective Lin." Thank you, I don't regret what I did. ”

Fujimoto frowned, thought for a moment, and said, "In Takashima's case, if you pay a large amount of bond, you should be able to bail out." If the guilty plea is good, a few months of probation will be about the same. ”

Upon hearing this, both Takashima and Ryoko showed a happy look on their faces, and it seemed that Miss Ryoko was very moved by what Takashima Motoya had done......

"Do things according to law. Takashima's affairs will be left to you. Lin Lei nodded and said to Fujimoto Police.

"Hi Yi!"

Just as Lin Lei was about to leave with Qiao Yan and Lu Yun, Fujimoto trotted in front of Qiao Yan and stopped talking.

Lin Lei smiled and asked, "Do you want to see the appraisal report in Forensic Doctor Qiao's hand?"

Fujimoto nodded again and again, and said curtly, "I'm sorry, I shouldn't have asked for it, but I still want to take a look." ”

Lin Lei continued to laugh, but shook his head resolutely: "It's better if you don't read this report." ”

As if realizing something, the Fujimoto police officer asked in a low voice, "Detective Lin, is it—"

The meaning is obvious after the words "is it not".

Lin Lei's smile was even bigger: "Guess what?"
