When Lin Xinyi hurried back to the Metropolitan Police Department, the Metropolitan Police Department was already in chaos.

As soon as they saw him, the officers seemed to see some savior:

"Steward Lin, you're back!"

Before Lin Xinyi could answer, they had a bitter face, and said to him in an anxious tone that a college student who had skipped class was shocked by the surprise inspection of the counselor:

"Let's go to the interrogation room!"

"Minister Odakiri, and the Hakuba Police Director, they're all here."

"The White Horse Police Inspector is here?" Lin Xinyi suddenly realized the seriousness of the problem:

It's just a thief, and even the top of the Metropolitan Police Department was alarmed.

This is equivalent to the Heavenly Court encircling and suppressing Huaguo Mountain, and the Jade Emperor himself carrying a gun into battle.

Actually, it can't be helped...

There was even a live TV broadcast outside the Metropolitan Police Department building, and even if Director Hakuba wanted to go home from work, he had to worry about being stopped by reporters.

With such a big formation, it was indeed necessary for him to come and see it for himself.

"I'll take a look." Lin Xinyi casually confessed a few words to those police officers, and then rushed to the interrogation room.

And when he arrived, in front of the interrogation room, Minister Odakiri and the Hakuba Police Chief were talking in a low voice, accompanied by a group of police officers who were afraid to come out.

"This is Lin Xinyi, Lin Administrator, right?"

Noticing Lin Xinyi's arrival, the director of the White Horse Police took the initiative to stop talking and look over.

He had a kind smile on his face, and he looked like a kind squinting uncle, as if he was not at all angry about tonight's farce.

"It's okay, you don't have too much pressure."

"It's good for young people to act quickly and decisively."

"Investigating the case is originally a process of encountering difficulties and solving difficulties, this time the suspicion of Black Feather Kuaito has been ruled out, and it will be necessary to continue to investigate in the future."

Director Baima always smiles when he speaks, like a leader who condolences at the grassroots level.

But as soon as Lin Xin heard this, he knew...

This uncle is an old onmyoji with one mouth.

It sounds like it's all comfort and encouragement, but it's actually a beating.

This is not to knock Lin Xinyi, after all, the police director will not get along with a newcomer who has just joined the company.

He was just secretly poking and prodding Minister Odakiri next to him to express his dissatisfaction:

Oda Kiri, do you trust this young man too much?

This kid is very capable, but after all, he is too young to take care of the overall situation.

Originally, as long as this case was dealt with in moderation, even if the thief Kidd could not be caught, the Metropolitan Police Department would have been able to use last night's operation in the clock tower to successfully restore public credibility.

But this kid is simple-minded and only thinks about catching thieves, and attacks decisively as soon as there is a clue.

As a result, arresting people during the day and making such a big move attracted a large group of media at night.

Isn't this baking yourself on the fire?

“......”

Minister Odakiri silently translated the leader's words in his heart.

His face was a little gloomy, but his gaze at Lin Xinyi was very calm, and even, with a hint of apology.

Because he knew that Lin Xinyi couldn't be blamed for this.

Lin Xinyi is just reasonably investigating suspicious candidates based on existing clues.

To blame, we can only blame the media's sense of smell too much, and the Metropolitan Police Department itself does not pay attention to secrecy.

"Lin, it's okay to make a mistake once."

"This is already the closest we've come to the truth, and we wouldn't have gotten here without you."

Minister Odakiri said this in a very firm tone.

Obviously, even if this investigation did not go well, he still chose to believe in Lin Xinyi's ability.

But at this time, Lin Xinyi gave him an unexpected answer:

"Something went wrong? It's too early to say that. ”

"That Black Feather Fight, it may not be the blame thief Kidd."

"Oh?" Minister Odakiri and Director Hakuba were both surprised: "Isn't the fingerprint comparison result out?" ”

"I know."

"But that doesn't tell the whole story – after all, that's Kidd the Thief."

Lin Xinyi didn't answer directly, but said in a calm tone:

"Give me a little more time, and I'll get an answer tonight."

The two big leaders glanced at each other, and they were also interested: "Okay." ”

And Lin Xinyi didn't explain anything more.

He directly pushed open the iron door of the interrogation room next to him, walked over to Kuroba Kaito and walked down.

Minister Odakiri and Director Hakuba also came in, allowing Kuroba Kaito to enjoy, probably the highest level of interrogation lineup in the history of the Metropolitan Police Department.

At this time, after more than half a day of repeated interrogation, his expression was already a little tired.

Seeing Lin Xinyi and the three of them coming in, Black Feather Kuaidou immediately shouted with an aggrieved face:

"Hey, hey... Mr. Lin Xinyi, and two other uncles. ”

"Isn't the fingerprint comparison all the results matched? How long are you going to keep me in lock? ”

"I'm really just an ordinary high school student, not a thief Kidd!"

Minister Odakiri was completely unresponsive, and now he just wanted to see how Lin Shinichi would solve the problem.

However, the director of the white horse took a few more glances at the black feather Kuaito:

Speaking of which, Detective White Horse, his son who is a famous detective, seems to be a classmate of this Black Feather Kaito.

That kid wouldn't know anything, would he?

Director Bai Ma thought secretly in his heart, but there was no expression on his face.

And in the silent gaze of these two big leaders, Lin Xinyi finally spoke:

"Kidd, when did you get your fingerprints removed?"

"I said I wasn't Kidd..."

"Besides, I've been locked up here for most of the day, how can I change my fingerprints?"

Black Feather Kuaidou's face was full of helplessness.

But he knew it very well in his heart:

Fingerprints or something, he secretly changed them last night.

As a strange thief Kidd, it's not easy to go to the Metropolitan Police Department to steal physical evidence?

He was rescued by Hongzi last night, went home and prepared masks and props, and then rushed to the Metropolitan Police Department overnight to replace the fingerprints collected by the forensic department from the scene.

Therefore, if you compare his fingerprints with those of "Kidd the Strange Thief", the results will definitely not match.

But that doesn't mean that Black Feather Kaito really doesn't have to worry at all.

In addition to fingerprints, there was something even more terrible, which he couldn't solve when he came last night.

"DNA, you should know that your DNA test hasn't been out yet, right?"

"Kidd's blood was personally brought back to the department for research and DNA testing overnight."

"I was watching the whole time, and by the morning, the DNA sequence of Kidd the Strange Thief had already taken effect."

"Now just wait for your DNA sequence to be identified, and you can directly compare it to the DNA sequence of Kidd the Monster Thief."

"If the results are consistent, then you're Kidd the Thief."

Lin Xinyi said in a calm tone the thing that Black Feather Kaito was most worried about.

And Black Feather Kaito couldn't help but feel a little apprehensive in his heart:

Indeed, when he came to replace the physical evidence last night, although he succeeded in replacing various examination materials such as fingerprints, blood, nails, and nail dirt without anyone finding out...

However, he was unable to prevent DNA identification and identification of the composition of the nail scale.

Because Black Feather is too late.

The magic show requires meticulous preparation, and the preparation for infiltrating the Metropolitan Police Department alone consumes a lot of effort.

By the time he infiltrated in the early hours of the morning, Kosoyan had already measured the thickness of his nails and easily confirmed the substance in the nail scale.

And this report on the composition of nail scale, which Black Feather Kuaidou itself did not pay much attention to, later became an important basis for Lin Xinyi to find out from the vast sea of people.

As for the DNA identification that Black Feather Kaito himself attaches great importance to, he wants to stop it, but there is no way to stop it.

Or is it because he came too late...

By the time Black Feather Kuaidou had infiltrated the research, the DNA sample of "Kidd the Strange Thief" had been amplified by PCR, loaded onto a porous gel made of agarose, and sent to the electrophoresis equipment.

And at this time...

The porous gel with DNA fragments on it looked like a large piece of jelly soaked in an energized liquid.

Black Feather Kaito never thought that the intermediate process of DNA identification would be like this.

He can replace all kinds of fingernails, fingerprints and other inspection materials, but he can't replace a thing that he has never seen before.

Not to mention, Lin Xinyi is particularly concerned about DNA identification.

He kept an eye on the instrument, not giving it a chance.

Then, when the time came in the morning, the appraisal report came out directly.

The identification report shows the genotyping of Kidd on 16 loci, and as long as you keep this report, you can use it to compare it with the DNA identification reports of other samples.

The report is stored directly in the Metropolitan Police Department's online database.

If you want to tamper with this report, you can't do it by conventional means.

There was no way, Black Feather Kaito could only give up temporarily and go back to prepare for another.

But who would have thought that within a few hours of his return, the Metropolitan Police Department would "invite" him back again.

"No way... I can only trust the old man Terai. ”

Terai Huangnosuke, Kuroba Kaito's criminal assistant, is also his last reliance now.

After he returned in the morning, he specially instructed Terai Huangnosuke that once he was accidentally caught, he would use the camouflage props he had prepared in advance to infiltrate the Metropolitan Police Department and interfere with the DNA identification work.

And as a special tool man for two generations of monster thief Kidd...

Mr. Terai not only has excellent abilities, but also knows a lot of scientific and technological talents.

Even if Kuroba Kaito is now in prison and can't help, he should have a way to tamper with the forensic report in the police database.

"Are you waiting for your accomplices to save you?"

Lin Xinyi suddenly said:

"The fingerprint comparison results do not match, indicating that the sample material has probably been secretly replaced by you."

"In that case, as long as you find someone to interfere with this DNA test, and then find a way to tamper with or destroy the DNA test report of 'Kidd the Strange Thief', you can completely get away with it, right?"

He coldly stabbed Black Feather Kuaito's heart.

But Kuroba Kaito has always maintained his poker face, and no flaws have been revealed.

"Alas..."Lin Xinyi shook his head helplessly, and said with a smile: "Do you know why I attach so much importance to DNA identification, and even only stare at this and not pay attention to others?" ”

"Because the information about the DNA sequence can be completely recorded in the identification report."

"An appraisal report is not an object, but information."

"It's easy to replace the sample, but it's hard to destroy the information."

"So, after Kidd's DNA report came out, I took it back to the forensic class and checked my office from start to finish."

"After making sure there were no listeners, cameras, or anything like that, I..."

"I just made some small preparations."

"What preparation?" Kuroba Kaito was always silent, but Minister Oda Kiri on the side asked curiously.

"Haha..."

Lin Xinyi smiled slightly.

Then, he squinted at Black Feather Kaito:

"Tell you what..."

"In addition to the DNA identification report of 'Kidd the Strange Thief', it is automatically saved to the Metropolitan Police Department's online database..."

"I secretly sent it to my mailbox, uploaded it to the web page, took a photo, copied it into a floppy disk, faxed it to me, and a few other reliable colleagues such as Twilight and Komatsu at home, and each printed 100 copies of the backup on A4 paper."

"If you have the ability, tell your accomplice to steal slowly!"
