Chapter 980

Han Bin and Liu Rong talk, has been paying attention to her expression, Liu Rong no emotional fluctuations, emotions have been relatively stable.

If Liu Rong is really Xiao Bingtian's Rong Rong, then their feelings must be very deep. Liu Rong is really a murderer. It's impossible to say that they are so indifferent.

Another is that Liu Rong is older than Xiao Bingtian. In addition, Xiao Bingtian is younger, and their appearance is nearly ten years worse. 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 only saw Liu Rong now, but he didn't see Liu Rong when he was young. Maybe Liu Rong was more beautiful when he was young. Many men like mature women.

In general, Liu Rong's suspicion is not big, but one thing Han Bin can't figure out is that although the deceased was seriously injured by a knife, he died soon, but the real life is different from playing games. He won't disappear immediately. Even if he is seriously injured, he can persist for a period of time, which is enough to call for help. This is in line with the characteristics of a person before death.

But Liu Rong, who lives upstairs, claims to have heard no unusual sound.

If what Liu Rong said is true, Xiao Bingtian should be gagged by the suspect after his serious injury, so he can't call for help.

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

According to Li can, a forensic doctor, except for the fatal wound on his chest, Xiao Bingtian has no other wounds or traces of being bound. That is to say, when Xiao Bingtian is sober, this hypothesis is not tenable.

There is another situation, that is, Xiao Bingtian is in a coma, even if he is fatally attacked, he can not call for help. This situation is true. In order to prove this point, we need to provide more practical evidence in the later autopsy.

This belongs to material evidence. Another faster way is to ask other neighbors whether they heard a cry for help yesterday. If other neighbors didn't hear any abnormal sound, it proves that Liu Rong didn't lie.

Han Bin went downstairs, and the technology department also completed the scene investigation.

Ma Xiwen said, "the scene has just been completed, we are ready to close the team."

"What do you find?"

"A sharp knife was found at the scene, with a blade of about 10 cm. It should be an ordinary fruit knife, but the quality of the knife is good, very sharp. Judging from the situation at the scene and the wound of the body, it is very likely that it was the murder weapon.

In addition, we found a broken cup in the kitchen. We collected pieces of glass. I saw the incomplete fingerprints on the broken glass. I'm going to take it back to the lab for splicing to see if I can recover the fingerprints.

Another discovery you should also notice is that we found a group of blood footprints at the scene. We have collected the footprints, sorted them out and sent them to your office.

Another point is that the situation at the scene makes me feel a bit confused. I'm not sure if this is the first scene

Han Bin nodded, "I just checked the scene, but also felt that there were some problems on the scene. Judging from the amount of blood, this should be the first scene. I prefer the victim to move after being injured. As for whether he moved himself or was dragged by the suspect, it is not known for the time being. "

"It's also possible," mahevin said

"Did you find the victim's cell phone?"

"No

"Did you find a picture of a young lady? The deceased is likely to carry it with him, and this picture should be some years old."

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

"Well, you go back first, and I'll go in and have a look." Han Bin clapped his hands and told several team members, "people who have no work on hand help me collect photos of the house."

"Yes."

Since becoming the squadron leader, Han Bin seldom does this kind of basic work by himself.

At this time, Wang Xiao brought people back, Hui reported, "team Han, I took people to make notes for several other neighbors who came to the scene."

"What do you find?"

"Although they have lived in this community for many years, they are not familiar with the dead, have not been close to the body, and have not found any suspicious places."

"During the time of the crime, did they hear the victim call for help?"

Wang Xiao said, "no, I'm just wondering about this. Although the dead are seriously injured, they can't die immediately. It's reasonable that they should call for help, but all the neighbors haven't heard any abnormal sound."

Han Bin touched chin, "wait for Li forensic further autopsy results."

Judging from the current situation, Xiao Bingtian may have lost the ability to call for help when he was injured. Since he did not resist the injury and was not tied up, it is likely that the drug caused the victim to be unable to move.

Zhao Ming came over, "team Han, I collected all the photos of the master bedroom."

Han Bin took the photo and began to look through it. At the same time, he recalled the photo, size, style and appearance he saw on the high-speed railway.

Han Bin looked twice, but did not find the photo Xiao Bingtian saw on the subway.Han Bin suddenly thought that he had overlooked a problem, he should ask Liu Rong for a young photo.

Then she denied the idea, because if Liu Rong was the murderer, she would not take out the photos collected by Xiao Bingtian.

Han Bin only remembers the size of the photo and only knows that it's a woman's photo, but because of the angle, he can't see the woman's face in the photo. Even if Liu Rong takes out the photo of her youth, Han Bin can't tell.

Han Bin continued to look at the photos, and soon saw all the photos collected by the team members, but did not find the same photo as his memory.

Han Bin didn't give up either. Although he didn't find the photo that Xiao Bingtian carried with him, Xiao Bingtian may not only have one picture of the woman, but other photos of the woman may be hidden in these photos.

Han Bin called Zhao Ming over and said, "I'll arrange a task for you to find out the identities of all the women in these photos."

Zhao Ming showed a touch of bitterness, "team Han, there are a lot of old photos on it. They've been decades. Their appearance has changed a long time ago. How can I check it?"

"That's your business. Think of your own way."

After arranging the task, Han Bin continued to observe the situation in the room, using criminal psychological analysis to restore the process of the crime.

Han Bin summed up all the clues and evidence. He still thinks that it's more likely to be an acquaintance, but there are some exceptions in some details.

For example, if the cup is broken in the kitchen, the suspect should want to clean the DNA and fingerprints left on the cup. At first, Han Bin thought it was broken after cleaning, but just now when the technical department investigated the scene, Ma Xiwen found fingerprints on the glass, which means it should have been broken before cleaning the cup.

Broken does not mean that DNA and fingerprints will disappear. It is reasonable that the murderer should collect glass fragments and take them away so as to destroy his own evidence. However, it is unreasonable that the suspect left the glass fragments at the scene.

Of course, if the suspect is in a hurry and worried about being found by others, he may not have time to clear the broken glass on the ground.

However, the crime happened the day after the death of the victim. It is reasonable that the murderer had enough time to escape. Unless, at that time, the suspect was disturbed or frightened by external reasons or people.

Another point is that the killer took the victim's mobile phone, which indicates that there may be some important things on the victim's mobile phone. But the tools of crime are equally important. When the suspect takes the mobile phone, he does not take the knife away.

Han Bin patted his forehead, and thought of a clue, the dead only found a knife at home, and this knife may be the victim used to cut apples, may also be the murder weapon to kill the victim.

So the question is, did the murderer come to the victim's house with other weapons, or just for a moment, they had a fierce conflict during the conversation, and the murderer picked up the apple knife on the table and stabbed the victim to death.
