When I thought of this, He Sheng and Gao Mingqiang had already come to the front of a room in Min Jiashu, and it was the waiter who had been bringing us over, so I walked slowly, because I sent a message to Du Yuting and asked her to help investigate whether Hao Xiangxue had a history of theft, and she quickly replied to me that this guy didn't know how many things he had stolen before.

It seems that my guess is correct, and Du Yuting told me that Hao Xiangxue's sister Hao Xiangmei is indeed dead, and the time is very close to what Hao Xiangxue said.

It turned out that Hao Xiangxue didn't lie to us in this matter.

At this moment, the waiter tapped on the door of Min Jiashu's room, and an impatient voice came from inside and said, "Didn't I tell anyone not to disturb my rest?" Are you going to rebel? ”

"No, boss, there are three cops looking for you!"

As soon as we heard the word police, we soon heard the sound of someone bouncing up from the bed and running to a place, when Gao Mingqiang and He Sheng took a step back and slammed the door, Min Jiashu had already jumped out of the window, but unfortunately, he was directly pressed to the ground by several policemen who were ambushed downstairs before he landed!

He really thought that we were not prepared, the policemen were already watching him, and before we went downstairs, we fumbled around the room where he was staying to collect some hair and fingerprints, and then found two books on psychology, and some ideas popped into my head at that time, it seems that some of the things about this bastard were guessed correctly, but there are also some things that I didn't expect.

Before He Sheng entered the interrogation room, I first worked with the people from the laboratory department to test the physical evidence, in fact, the hair we collected back did not have hair follicles, because those fell out naturally, and some people may think that hair without hair follicles is undetectable, that was in the past, not now.

In fact, DNA can still be detected in hair without hair follicles according to current technology, because hair without hair follicles (hair shaft) also contains genetic information, but at present, only mitochondrial DNA can be made from hair shafts in China.

Mitochondrial DNA is only inherited by females, which means that your matrilineal clan relatives all have the same mitochondrial DNA, which can be used as the basis for individual identification and blood relationship identification, but the degree of identification is relatively low, but there are forensic anthropologists in our forensic department, and it is very possible to find the DNA of Min Jiashu through hair.

Then there are his fingerprints, we really found some corresponding information in the database, what I didn't expect was that he had been a thief like Hao Xiangxue, and the two were sentenced to prison for a period of time at the same time, and when they met again after they came out, plus Hao Xiangxue's sister was gone, so the two were together.

Hao Xiangmei committed suicide when the two of them were in prison because they were worried about excessive depression, and her parents did not believe that the cause of death was determined by medical examiners, and the results finally confirmed her suicide.

I looked through her file at the time, and in that case, it should be a petition case, and I checked it in the archives and found a report.

At that time, the forensic doctor did not find any unusual scars on Hao Xiangmei's body, the syringe used to inject an overdose of morphine into her hand to commit suicide was her own fingerprints, there were only her own footprints in the house and no second person, and the surveillance did not see the picture of someone entering her house, and after investigation, it was found that Hao Xiangmei was very depressed before the accident, which already showed that she committed suicide.

There is nothing suspicious about this case, but there are only traces left by Hao Xiangxue on the deceased's body, and I didn't figure out what role Min Jiashu played in the case, but when I saw that there were a lot of suggestive words left in the psychology book, I realized that something was wrong.

I found Dao Zhiyong for the first time where the document inspection room is located, he is the section chief of our handwriting identification department, although he is the only one in this department, but this guy is definitely also a person, he is a character measurement expert specially taken back by He Sheng.

At that time, my master, Forensic Doctor Liang, was also here, and the two seemed to be studying some cases.

I saw that Master must have said hello first, and found that I was holding a book in my hand, and Master quickly understood: "It seems that Mr. Monkey, you have a job again, thank you for your betel nut!" ”

Master took the betel nut and gave me a look and left, and then I came to the monkey's side, which was deliberately called by the people in our bureau, but it only meant that he had a smarter head and a thinner body.

This guy is not black, and his limbs are full of hair, he is not tall, and he is always bent over, and he is usually a little naughty, so there is nothing wrong with everyone calling him a monkey.

When I opened the book to him, the monkey exclaimed, "This thing is really interesting, but you have to help, Chen Kang!" ”

In general, only Du Yuting and Gao Mingqiang will call me "Ah Kang", otherwise most people will call me by my name directly, I hummed and approached Dao Zhiyong, he turned on a purple lamp, and then erected a few uneven mirrors, supported by some blue brackets, and then raised his head to turn on a chandelier on his head, and started an ancient typewriter in the desk drawer!

If this strange operation were changed in the eyes of others, it is estimated that I would have complained a long time ago, but I have seen it with the people of the number one serious crime team, so there is no surprise.

On the contrary, I was wholeheartedly helping Dao Zhiyong to complete his purple light word measurement this time!

Under the effect of the purple light, the rays of light were originally shining around, but because of the comprehensive effect of the mirror, these rays were refracted countless times and then concentrated on the psychology book opened in the middle.

Now this book has opened to the page that I found problematic before, Dao Zhiyong observed everywhere from left to right, his head tilted, almost half of his face was attached to the top of the book, I was actually worried that he would destroy the physical evidence, but seeing his so focused appearance, I was afraid of interrupting him, and after a while, he picked up a magnifying glass with the help of a strong purple light and carefully observed the handwriting!

I hadn't seen anything, but when my eyes fell in the direction of his magnifying glass, I suddenly noticed that there seemed to be some small bumps on the handwriting......
