There are only a few pens on the note, but I will never forget that it was definitely Du Lei's handwriting. Handwriting identification is a compulsory course for detective science majors, I have a lot of research on handwriting identification, Du Lei's handwriting is very familiar to me, and the memory of my cerebral cortex immediately automatically made a preliminary comparison with the handwriting on the photo.

My hand shaking as I held the photo, I put it down and asked to see the original. The criminal police glanced at me and didn't say anything, the Public Security Department had already notified the police station, my request was not excessive, and soon, he took the original of the three notes. The note is wrapped in a special identification bag.

All three notes were a little wrinkled, and it looked like they had been crumpled up and unfolded when the police found them. Touching the original note, I am even more sure that the handwriting on it comes from Du Lei. I took a deep breath and took a closer look at what was written.

The few pens were written with a fountain pen, which seemed to be running out of ink, and the handwriting seemed a little faded. Three notes, three signatures, were addressed to me, Xu Yi, and Meng Ting.

Meng Ting: I love you.

Xu Yi: I'm sorry.

Li Ke: I'm sorry.

That's all there is to the note. I still have a bit of luck in my heart, I expect that it is not Du Lei who will die, but a person who looks exactly the same as Du Lei, but whether it is the handwriting on the note or the signature on the note, they are telling me that the person lying in the morgue is Du Lei.

"Professor Li, the Li Ke on this note should be you, right?" I held the note and stared at it for a long time, and the detective asked me.

I nodded smugly.

Detective: "You said you recognized the deceased, so does the handwriting look like that of the deceased?" Or, do you have any written materials from the deceased, and we would like to do another handwriting test. ”

I still nodded: "Let's wait for the police academy file to arrive." "There is also Du Lei's autograph on the file, in this world, there are many people who are good at imitating other people's handwriting, and the written materials they write are difficult to distinguish between true and false even professional investigators in the criminal department, not to mention that I only identify them through the surface.

The detective took the notes back, and he told me that the notes were found in the pockets of the deceased, and that there was nothing else on the deceased's body except for three notes. Next to the coffin where he was lying, a fountain pen was found that was about to run out of ink, and the police had preliminarily determined that the fountain pen was the deceased's tool for leaving books.

The three notes were identified by the police as the deceased's suicide note, so they had no intention of investigating further, and if it weren't for me and Jiang Jun who happened to be here, the case would probably be closed. At my request and with the help of the leadership of the Public Security Bureau, the police made a decision to conduct a more detailed investigation of the case.

This case seems to be that the deceased committed suicide by taking sleeping pills, but there are still doubts. The biggest doubt is why the deceased committed suicide at Xu Yi's house, and carried a coffin to Xu Yi's house. At my suggestion, the police decided to start with the coffin. According to the town's neighbors and residents, no strange people have been seen entering the town in recent days, let alone strange people entering Xu Yi's house.

Xu Yi's house is located in a relatively concentrated residential area in the town, where people come and go during the day, and everyone in the town knows that Xu Yi is the only one left who owns the house, so if anyone enters, everyone will definitely find out or stop it. It is impossible for a coffin to appear in Xu Yi's house out of thin air, the four walls of Xu Yi's house are intact, and the only thing that can provide such a large coffin to enter is the door of his house.

The door has a large lock, and it is actually not difficult to enter the house without a key and without breaking the big lock, because many people have mastered the art of unlocking, such as locksmiths, or thieves. However, it is absolutely impossible to lock the big lock in the house after entering the house.

Therefore, after the deceased entered Xu Yi's house, there must have been another person or people outside the house who locked the house.

Moreover, it is impossible for the deceased to carry a coffin as heavy as one person, which requires multiple people to complete. The town is so small, and someone must know that someone carried the coffin into the town and into Xu Yi's house during the day, so I concluded that the coffin was carried into Xu Yi's house in the middle of the night when no one was around.

There is only one coffin shop in town, and the police have sent someone to investigate, but the owner has denied that the coffin came from their shop. The boss showed the police a few coffins they had beaten, and the wood of those coffins was very poor, because they were sold to poor people, so the price was not expensive.

But the coffin where the deceased was lying was of good wood, and the price should be expensive. The police ruled out the suspicion of the shop owner.

Since it is not a coffin purchased in the town, it is outside the town, according to the distance, the nearest town to Xu Yi's hometown, it takes more than an hour to drive, that is to say, the coffin cannot be carried by hand, but sent to the town by transportation.

The means of transportation that can accommodate such a large coffin should be a medium and large car, there are few outsiders in the town, if you get into a medium or large car, whether it is in the day or night, the sound of the engine will be very loud, but the residents still say that they have not heard this sound.

It is inferred that the transport of the coffin stopped at a distance from the residential area, and then the coffin was carried to Xu Yi's house on foot, which determined that the coffin was not carried by the deceased alone. It is more troublesome to transport the coffin, and when you pass the city or provincial inspection, you may be stopped by law enforcement officers.

If the deceased really wanted to commit suicide, it would definitely not cause unnecessary trouble, so the coffin must have been purchased in a town relatively close to Xu Yi's hometown. I asked the detective to take the pictures of the coffin to the coffin shops in several nearby towns to investigate and see if anyone admitted that the coffin originated in their shop.

If the source of the coffin cannot be found, then this case is more likely to be a murder. Only in murder cases, the murderer will deliberately leave the police without a trace, and in a simple suicide case, the deceased will not think so much.

The police immediately followed my suggestion, and I waited for the police academy to transfer Du Lei's file to this police station, and on the other hand, for the forensic autopsy report with legal effect.

A large amount of sleeping pills were found in the mouth of the deceased, and taking a small amount of sleeping pills can inhibit the excitatory nerves in the cerebral cortex and help people fall asleep peacefully, but if they are taken in large quantities, they may cause shock, fainting and even death. Many people commit suicide and choose to take sleeping pills.

The police had issued a notice, but a day had passed and no one had come to claim the body, and with my identification, the police presumed that the deceased had no relatives. According to the procedure, if there are no relatives of the body, the police may, in special circumstances, conduct an autopsy on the body without the consent of the other person.

The police asked me for my opinion beforehand, because I might have been a good friend of the deceased, and I agreed, and I also thought of the real cause of death of the deceased. While waiting outside the identification center, I was so upset that I didn't call Meng Ting, the identity of the deceased had not been finally confirmed, and I didn't want to cause unnecessary trouble.

I don't know how to talk to Meng Ting, out of responsibility, I have to tell Meng Ting the news.

I didn't eat all day, during which Jiang Jun went out to buy something, but I had no appetite, and finally, anxiously waiting, the forensic doctor came out of the autopsy room. He was wearing a white medical robe, and sweat was dripping from his forehead behind the medical cap.

The police and I immediately asked about the results of the forensic examination.

The medical examiner said that the written autopsy report would be given later, but he told us about the condition of the body. On the surface, as I have observed, there are no other bleeding wounds or bruises found on the body of the deceased, except for some old scars, that is, the deceased died voluntarily, or did not resist or could not resist.

The forensic doctor conducted an autopsy on the body, and in addition to the sleeping pill residues found in the oral cavity, the forensic doctor also found a large number of sleeping pill residues in the deceased's body, and according to calculations, the forensic doctor believed that the deceased had eaten hundreds of sleeping pills. This kind of dosage, in the absence of timely rescue, can be said to be certain death.
