The next day, the police station of the western district of Baigang City.

Tong Lie sat at his desk, his hand on his forehead, and looked at the investigation report of Ji Dongshun's death yesterday. The cigarette butts in the ashtray had been piled up into a small mountain, and he had been thinking about it all morning, and doubts were rife.

Ji Dongshun's "accident" is too strange, and this must be related to the accident two years ago. If this so-called "accident" was not an accident, what method did the murderer use to kill him? Secret rooms can be faked, such as locked windows and security chains hung on doors, which can be artificially closed on the outside through special fine-wire mechanisms. But apart from a few traces of the attacker last night, there was no evidence in the house that he had killed him. And who the hell is that attacker? If the attacker was not the murderer, but had just arrived at the scene, did he have the same purpose as himself? The same purpose? The purpose is the same...... Tong Liehu was dumbfounded! Suddenly I remembered someone!

At this time, Zhang Fan knocked on the door and came in, and said with a little excitement: "Master, there is a new discovery!" ”

"What discovery?" Tong Lie's eyes lit up and he asked.

"We were in the next room to Ji Dongshun and found that the room had been cleaned. The cleanliness of the cleaning was so clean that not even a single footprint was left. It's so abnormal, there's no management at all for a hacking stack like this, and it's only cleaned up once in a long time. And even if it's cleaning, it's just casual and perfunctory. How is it possible to leave not a single footprint? Where are the footprints of previous residents? So I went out of my way to ask the bald clerk. He said he hadn't cleaned his rooms recently. Moreover, no signs of cleaning were found in the other rooms! Zhang Fan reported.

"That's right! The same too clean, and Ji Dongshun's room! Just ask a black hotel with no management and a fugitive from the end of the world, who has the kung fu to clean the room so clean? Nothing but himself and last night's suspect with no one else's footprints? Tong Lie slapped the table and said.

"There's something even more interesting! We found some gum at the corner between the ceiling and the wall in the cleaned room. It looks like someone has used something like strong transparent glue on it! Zhang Fan added.

"Hehe, that's true, call everyone to a meeting!" Tong Lie knocked on the table and got up and walked out of the office......

5 minutes later, the police station conference room. The cadres of the Criminal Investigation Brigade who did not have an assignment sat inside and listened to Tong Lie's reasoning about the case.

"The basic findings of the case are here, and based on these results, I speculate that Ji Dongshun's death was not an accident, but should be an organized and planned murder carried out by a gang!

Ji Dongshun's first place of death was not in his own house, but in the cleaned room next door. The murderer should have wrapped the entire room with several huge sheets of thick waterproof plastic sheeting before committing the crime. After committing the crime, they were all torn off, and the scene was thoroughly cleaned before leaving calmly. That's why we found that the room had been thoroughly cleaned, and there were traces of scotch tape in the corners and near the ceiling! ”

"Why did the murderer go to such great lengths?" Zhang Fan asked

"The reason why the murderer did this was because of the bloodstains, on the one hand, to prevent the bloodstains from spilling into all corners of the house, which was difficult to clean up thoroughly; On the other hand, it is for the collection of blood! Of course, all this is to disguise Ji Dongshun's death as suicide! ”

"Collect blood?" A police officer was puzzled when he heard this.

"Yes! Collect blood! Because if you want to disguise yourself as being stuck in the throat by a broken glass, it will be a non-instantaneous death process. Before Ji Dongshun dies completely, more blood will inevitably flow out. If we were at the second scene, that is, Ji Dongshun's room, and found that there was a problem with his blood loss, we would immediately rule out an accident or suicide! Tong Lie said

"I'll go, this murderer has thought well enough!" Another officer lamented.

"Not 'this', but 'these'! There should be more than one murderer, because of time! First of all, I checked the layout of the inn, and the restrooms were too small for one person to enter. Therefore, the murderer chose to commit the crime in the room, and the modus operandi of such a big battle, the preparation work in advance and the finishing work after the clean-up work are very time-consuming and energy-consuming work. Ji Dongshun died at about three o'clock in the morning, and the murderer had to complete the layout of the second scene and the cleaning of the first scene before dawn. So I judged that it was a gang!

The murderer should have completed the arrangement with his accomplices, and led Ji Dongshun to the next room in a certain way at midnight. It is speculated that the murderer should know Ji Dongshun, or have some reason to persuade him to go. Most likely, he was invited directly into the house through his mobile phone. We did not find his mobile phone at the scene, and we can suspect that he sneaked back to White Harbor, so in order to prevent tracking and positioning, so he did not carry his mobile phone. But according to our investigation, he had called P on the phone before his death, and had ordered takeout twice. Therefore, Ji Dongshun should have carried his mobile phone with him, so where did his mobile phone go? ”

"Taken by the murderer?" Zhang Fan asked.

"Quite possibly! It is possible that the murderer asked him to come to the next room by phone call or text message. And after he entered the room at the first scene by appointment, he must have noticed the abnormality in the room for the first time. But the killer must have used a weapon such as a firearm to coerce him into the house, while another person restrained him from behind and plunged the broken glass that had been prepared into his throat.

Ji Dongshun took a large dose of viagra in front of him, and he recruited P, coupled with a hangover, his body should be in a relatively weak state. As long as the murderer is a strong man, he will be inserted into his throat while embracing him. Or with the use of drugs, the traces of resistance on his body should not be obvious and easy to ignore. Tong Lie said a lot in one breath, a little thirsty, picked up the teacup and took a sip of water.

"Then since the murderer had contact with Ji Dongshun, why didn't we find any skin tissue or hair left by the murderer on him?" Zhang Fan asked

"The murderer who came into contact with Ji Dongshun should have worn a raincoat and rubber gloves in advance. In other words, the murderer is like that room, wrapping himself tightly! Judging from this, these people are very well prepared, their criminal methods are quite clever, and they have a strong sense of anti-reconnaissance! Tong Lie said.

In other words, the murderer killed Ji Dongshun next door, and then used the key that Ji Dongshun carried with him to transport Ji Dongshun back to his own room, so there was no trace of the door being picked. But what is the explanation of the safety chain that can only be put on from the inside? The murderer created an accident scene, and the battle was so big, didn't anyone find out in the process? Zhang Fan followed Tong Lie's train of thought and asked questions.

"The safety chain only needs to pass through a tool like thin wire, tough hair, and with some clever means, it can be put on outside the door. After the murderer faked the scene of the accident, he completely cleaned up the next room and retreated. The more people there are in this process, the faster it will be completed. And there should be someone outside the house who is keeping watch for them. In addition, it was around 3 o'clock in the morning, which was the time when everyone was asleep, and the composition of the inhabitants of the hacker stack was relatively complicated, so there were no strong witnesses! There is also one of the most obvious suspicions, the glass that killed Ji Dongshun is not the standard configuration of this hacker stack room. Imagine how likely it is that a wanted criminal sneaks back to White Harbor and carries a fragile glass with him? So as far as I can judge, it was a premeditated murder carried out by a highly intelligent criminal gang of at least three or four people! Tong Lie said firmly.

"When did we have such a clever criminal gang in White Harbor City? It's a pity that the secret is sparse, and you still found a flaw by the master! Zhang Fan admired.

"Ji Dongshun secretly returned to Baigang City only before yesterday, and the murderer was too hasty to carry out a closed room murder case that was faked as an accident in such a short time. I feel that if we had given this gang a longer time to plan and prepare, we might not have been able to find such clues and flaws so easily. Tong Lie said in a deep voice.

At this time, he thought in his heart that if he hadn't been suspicious and looked at the problem with preconceived ideas, he was afraid that this time he would also be treated as an accident. If the Westside Tower billboard accident two years ago was not an accident, but also a premeditated murder, could it have something to do with this gang?

"Master, what should we do next?" Zhang Fan asked.

"First of all, check Ji Dongshun's lost mobile phone and communication information, and the number can be started from the prostitution lady or the food delivery store; Second, let the technical department expand the access to surveillance data near the hacker stack, and don't let anyone suspicious go. Finally, increase the scope and intensity of the investigation, and strive to find eyewitnesses! In terms of the grouping of investigators, Zhang Fan, you will arrange it. Alright, do as I say, adjourn! Tong Lie commanded.

"Yes!" Everyone received the order and walked out of the conference room one after another.

"Zhang Fan! Wait a minute, check my personal ......" Tong Lie stopped Zhang Fan, wrote a person's name with a pen and paper on the table, and handed it to Zhang Fan.

Zhang Fan took the note and opened it curiously, and there were two words written on it: Jiang You!
