When Han Bin talked to Liu Rong, he kept paying attention to her expression. Liu Rong did not experience any emotional fluctuations and her emotions were relatively stable.

If Liu Rong was really Rong Rong as Xiao Bingtian said, then the relationship between the two must be very deep. Liu Rong is really the murderer, and it is impossible to say so lightly.

Another thing is that Liu Rong is older than Xiao Bingtian, and Xiao Bingtian is younger, and the appearance of the two is nearly ten years different. At least in Han Bin's opinion, Liu Rong is not worthy of Xiao Bingtian.

Of course, Han Bin's idea is a bit subjective. After all, he has only seen Liu Rong now, and has never seen Liu Rong when she was young. Maybe Liu Rong was more beautiful when she was young, and many men like mature women.

In general, Liu Rong is not very suspicious, but one thing that Han Bin can't understand is that although the deceased died shortly after being seriously injured by a knife, his life in reality is different from playing games and will not disappear immediately. Even if he is seriously injured, he can persist for a while, which is enough to call for help, which is in line with the characteristics of a person before his death.

But Liu Rong, who lives upstairs, claimed that she did not hear any abnormal sounds.

Assuming what Liu Rong said was true, then Xiao Bingtian should have been blocked by the suspect after being seriously injured, so he was unable to call for help.

The suspect blocked Xiao Bingtian's mouth. Xiao Bingtian must have to resist, and his struggle before his death will be very intense, and there will definitely be some resistance injuries on his body.

According to forensic doctor Li Can, except for the fatal injuries on the chest, Xiao Bingtian had no other wounds on his body, nor had any signs of being tied up. In other words, when Xiao Bingtian was awake, this assumption was not valid.

There is another situation, that is, Xiao Bingtian is in a coma and cannot call for help even if he is fatally attacked. This situation is valid. To prove this, it requires more tangible evidence from the forensic later autopsy.

This is physical evidence, and there is a faster way to ask other neighbors if they heard the cry for help yesterday. If other neighbors did not hear abnormal sounds, it proves that Liu Rong did not lie.

Han Bin went downstairs and the technical department also completed the on-site investigation.

Ma Xiwen said, "The site survey has just been completed and we are ready to withdraw the team."

"What's the discovery?"

"A sharp knife was found at the scene, with the blade of only about ten centimeters. It should be an ordinary fruit knife, but the quality of the knife is good and very sharp. Judging from the situation at the scene and the wounds of the corpse, it is very likely to be a weapon.

In addition, we found a broken cup in the kitchen. We collected the glass fragments. I saw broken fingerprints on the broken glass and prepared to take them back to the laboratory to splice them to see if the fingerprints can be restored.

Another discovery you should have noticed was that we found a set of blood footprints on the scene. We have collected shoe prints and sorted them out and sent them to your office.

Another point is that the situation on the scene gave me a bit confusing, and I'm not sure if this is the first scene."

Han Bin nodded, "After I checked the scene just now, I also felt that there were some problems on the scene. Judging from the amount of blood, this should be the first scene. I prefer that the victim moves after being injured. As for whether he moves by himself or is dragged by the suspect, it is unknown for the time being."

Ma Xiwen said, "There is also a possibility."

"Have you found the victim's cell phone?"

"No."

"Have you found a photo of a young lady that the deceased will probably carry with you, and this photo should be a few years old."

Ma Xiwen shook her head, "I didn't find it, but there are some old photos in the bedroom, you can go and take a look."

"Okay, you guys go back first, I'll go in and take a look." Han Bin clapped his hands and ordered several team members, "The person who is not alive on hand can help me collect photos from the house."

"yes."

Since becoming the squadron leader, Han Bin has rarely done this basic work by himself.

At this moment, Wang Xiao brought people back and reported, "Captain Han, I took people to record the other neighbors who have been to the scene."

"What's the discovery?"

"Although they have lived in this community for many years, they are not familiar with the deceased, have never approached the corpse, and have not found any suspicious places."

"Did they hear the victims call for help during the incident?"

Wang Xiao said, "No, I'm wondering about this. Although the deceased was seriously injured, it was impossible to die immediately. Logically speaking, he should have called for help, but all the neighbors heard no abnormal sound."

Han Bin touched his chin, "Let's wait for the results of Forensic Li's further autopsy."

Judging from the current situation, Xiao Bingtian may have lost the ability to call for help when he was injured. Since he had no resistance and no binding, it means that it is likely that the victim was unable to move due to the drug.

Zhao Ming walked over, "Captain Han, I have collected all the photos of the master bedroom."

Han Bin took the photo and started to look it up, and at the same time he recalled the photo he saw on the high-speed rail, size, style, and appearance.

Han Bin looked through it twice, but he couldn't find the photos of Xiao Bingtian looking on the subway.

Han Bin suddenly thought that he had overlooked a problem, and he should ask Liu Rong for a photo of his youth.

Then he denied this idea because if Liu Rong was the murderer, she would definitely not have taken out the photos collected by Xiao Bingtian.

Han Bin only remembers the size of the photo, only knows that it was a photo of a woman, but due to the angle, he could not see the appearance of the woman in the photo. Even if Liu Rong took out the photo of her youth, Han Bin could not tell it.

Han Bin continued to check the photos and quickly finished all the photos collected by the team members, but did not find the same photo as in his memory.

Han Bin did not give up. Although he did not find the photos that Xiao Bingtian carried with him, Xiao Bingtian might not have only one photo of the woman. Other photos of the woman were hidden in these photos.

Han Bin called Zhao Ming over, "Assign a task to you to find out the identities of all the women in these photos."

Zhao Ming showed a bitter feeling, "Captain Han, there are many old photos on it, which have been decades and have changed their appearance long ago. How can I check it?"

"That's your business, think of a way."

After arranging the task, Han Bin continued to observe the situation in the room, used criminal psychology to analyze it, and restore the incident.

Han Bin summarized all the clues and evidence, and he still felt that it was a familiar person who committed the crime, but there were some abnormalities in some details.

For example, the cup was broken in the kitchen, and the suspect wanted to clean the DNA and fingerprints left on the cup. Han Bin thought it was broken after cleaning, but when the technical science surveyed the site just now, Ma Xiwen found fingerprints on the glass, which means that it should have been broken before cleaning the cup.

Broken down does not mean that the DNA and fingerprints will disappear. It is logical that the murderer should collect glass fragments and take them away so that his evidence can be destroyed. However, the suspect left the glass fragments at the scene, which is somewhat unreasonable.

Of course, if the suspect is in a hurry when committing the crime and is worried that he will be discovered by others, he may not have time to clean up the broken glass on the ground.

However, the incident occurred the day after the victim died. It is said that the murderer had enough time to escape unless there was external reasons or interference at that time, which scared the suspect.

Another point is that the murderer took away the victim's mobile phone, which shows that there may be some important things on the victim's mobile phone. However, the tool for the crime is equally important. While the suspect took away the mobile phone, he did not take away the murder knife.

Han Bin patted his forehead and remembered another clue. Only one knife was found in the deceased's home, and this knife might have been used by the victim to peel apples or as a weapon to kill the victim.
