"Well."

Lin Xinyi unceremoniously handed him paper and pen, as well as a calculator:

"I will measure, you will calculate, speed up the work."

An agent who can even count sniper ballistics won't be able to make mistakes with his calculator.

So he confidently handed over the work of counting to Jiang Gu Ling, and he also said in passing:

"Don't make a mistake."

"The measurement and calculation of each blood drop must be accurate, otherwise the final error will be quite terrible."

With that said, Lin Xinyi continued to work hard.

This job is tedious:

He had to select a concentrated area of ​​blood stains first, then measure the length and width of each blood droplet in the concentrated area, and calculate the angle of incidence.

Confirm the direction according to the "head and tail" of the oval blood drop, and then use the "drawing method" to locate it according to the directionality and incident angle of the bloodstain.

That is to fix a section of the line at the end of the bloodstain, and the fixed point is located at the end point on the long axis of the bloodstain that is away from the tail of the bloodstain.

Then extend the line in reverse along the calculated direction and angle.

Finally, the intersection of several bloodstain extension lines above the plane is the location of the bleeding point.

This work is very meticulous and cumbersome, not to mention prone to errors, and the operation of pulling up multiple lines is also extremely complicated.

Its operation is so difficult that even in this world, those strange murderers who have eaten the "thread fruit" will have to bow down.

If it is in the future, the "computer program method" can be used to replace this cumbersome "drawing method"

You only need to take a digital camera to take a picture of the bloodstains at the scene, and then put the photos into the bloodstain analysis program, and the results can be obtained quickly.

But in this day and age, mobile phones are still Nokia, and this is the only way Lin Xinyi can use.

Only with the utmost care and fatigue can the location of the bleeding point be found out relatively accurately.

Lin Xinyi just kept busy.

He carefully squatted in front of the bloodstain, carefully measured, calculated, and pulled the thread, even though his forehead was covered with sweat, he did not stop working.

Finally, the results came out.

"Calculate the height of the bleeding point, connect the knife entry angle, the height of the deceased, and determine the murderer's height..."

Lin Xinyi felt helpless for the result:

"Maybe not even 1 meters."

"I'm afraid, this guy is just a middle school student."

"This...junior high school student?"

If it is a middle school student, it must be younger than 16 years old.

Kazami Yuya still wants to avoid this answer:

"Mr. Lin, could the murderer be... congenital dysplasia?"

"Did you say a dwarf?"

"That's not impossible."

Lin Xinyi sighed deeply, and his tone became more complicated:

"But think about it if you're an adult and you know you're short and you don't have much strength."

"Do you dare to break into someone's house with a hammer and attack a strong adult male?"

Officer Kazami was speechless:

Indeed, the murderer is not only short in stature, but also has a high temper.

What's more terrifying is...

"The murderer has such confidence. Apart from being young and impulsive, it is also very likely because he knows that he is a minor:"

"He knows that even if he enters a house with a weapon and kills someone, it doesn't matter if he succeeds or fails..."

"No one else can do anything about him."

Chapter 366 The Disappearing Juvenile Prisoner

Mrs. Yamazaki, who was temporarily invited by the police to drink tea, was soon invited to the scene of the crime.

This is what Lin Xinyi requested.

Now the criminal profile of the murderer has been roughly drawn out:

Minor, under 1 meters tall, presumed to be a junior high school student, who had a grudge against the deceased Mr. Yamazaki.

With this in mind, the case is almost over.

With these specific details, it should not be difficult to find the murderer.

When Lin Xin invited Mrs. Yamazaki over, he wanted to know the situation face to face with her, and asked if the deceased had any gangsters during his lifetime.

"Have a grudge against my husband... a junior high school student?"

Mrs. Yamazaki looks very haggard.

Her eyes were red and swollen, and there were still dry tears on her face. It looked like she had cried all night for her husband's death.

But at this moment, maybe she has cried enough, the sadness on her face has completely turned into a calm, a kind of death-like calm.

"I do remember one person..."

Mrs. Yamazaki replied flatly:

"That's a 14-year-old punk."

"About a year ago, that guy was blackmailing elementary school students with a knife on the street. My husband happened to pass by and took him to the police station."

"I heard that he was sent to a juvenile reformatory, but he was released after half a year."

"After he came out, this guy has been harassing our couple for a while... Later we called the police and contacted his parents to let him calm down."

"If you want to find him, I can provide his home phone number."

"Understood..." Lin Xin nodded.

He didn't call directly to ask if he wanted to catch the murderer. He didn't call to inform him first.

"Officer Jiang Gu, officer Kazami."

"It shouldn't be difficult to find the suspect's address, and I ask you to bring someone to the door and bring that little bastard under control."

"no problem."

Furutani Rei and Kazami Yuya nodded in unison.

The two of them led a team, and the secret police of the public security came to check the water meter. The little gangster would definitely not escape.

Lin Xinyi confidently handed over the matter of arresting people to professionals like them.

Then, apart from the police officers who stayed behind, only him and Mrs. Yamazaki who looked dull and depressed were left.

Mrs. Yamazaki seemed very reluctant to stay in the house where her husband died.

She walked out of the villa with an uncomfortable expression, and stood blankly at the door.

"Ms. Yamazaki."

Lin Xinyi walked up to her quietly, and asked without thinking:

"Last night, from 0:1 when the izakaya closed to 20:[-] when the police called you, where were you?"

"Huh?" Mrs. Yamazaki frowned tightly: "Didn't you police ask these questions?"

"I want to double check."

Lin Xinyi tried his best to sound gentle.

But his inquiry still made the widow very unhappy:

"I lived in the store and didn't come back."

"When I got the call and rushed back, my husband..."

Mrs. Yamazaki choked up and couldn't speak.

Lin Xinyi carefully kept silent, giving the other party time to mourn.

But in the end, he couldn't hold back anymore and asked someone an incomprehensible sentence:

"Ms. Yamazaki, do you...have a gun at home?"

"What do you mean?"

Mrs. Yamazaki's reaction suddenly became violent:

"What are you trying to imply by asking me that?"

"Are you trying to say that I killed someone?!"

"No, no, no..." In Lin Xinyi's voice, there was an unprecedented weakness like "justice".

It seems that the investigation he is doing at the moment is not a good thing.

But he still insisted on investigating:

"I just want to know the truth."

"Mrs. Yamazaki, if you and your wife are legally holding guns... even if you don't say it, we can quickly find it in the file."

"So, I hope you can..."

"Cooperate with you?"

There was a sneer at the corner of Mrs. Yamazaki's mouth:

"What's the use of cooperating with you?"
