Han Bin wasn't sure, but it was obvious that Rong 'rong was very important to Xiao Bingtian.
The fact that Xiao Bingtian kept that old photo and carried it with him meant that he cherished it.
Logically speaking, this kind of photo should only be taken out when there was no one around, such as at home or in his car. However, Xiao Bingtian looked at it on the high-speed train. There were a lot of people sitting next to him, so it wasn't suitable to look at private photos.
There must be a reason for such an unreasonable situation.
Han Bin thought that the biggest reason was that the woman named Rong 'rong was in Qindao. As the high-speed train approached Qindao, Xiao Bingtian became more and more excited. That was why he couldn't help but take out the photo.
Of course, if that was the case, it could only mean that the person in the photo was very important to Xiao Bingtian. It couldn't prove that Xiao Bingtian's death was related to her.
However, after Xiao Bingtian was killed, the photo that he carried with him disappeared. This was the key question.
If the murderer didn't know the person in the photo, why would he take away an insignificant photo?
Han Bin wasn't very satisfied with Song Xiaodong's interrogation.
Although Song Xiaodong admitted to going to Xiao Bingtian's house during the time of the crime, she didn't admit to killing Xiao Bingtian.
With the current evidence, Han Bin couldn't prove that she was the murderer.
Moreover, Song Xiaodong couldn't prove her innocence either.
Without new clues, it would be difficult to make further breakthroughs in the interrogation.
Han Bin left the interrogation room, leaving Li Qin and Ma Jiaoxu to fill in the details.
After returning to the office, Han Bin continued to study the bloody footprints at the crime scene …
The next morning.
In the conference room of the Municipal Criminal Investigation Unit.
Early in the morning, Han Bin held the third case summary meeting, which was attended by people from the forensic and technical departments.
Han Bin took a sip of tea to moisten his throat. "Let's have a formal meeting. There are more clues in the case, so everyone should report the progress of the investigation. Li Qin, tell us about Song Xiaodong's situation. "
Li Qin sorted out her thoughts. "Song Xiaodong admitted to going to Xiao Bingtian's house, but she didn't admit to killing Xiao Bingtian. I checked the neighborhood's surveillance. Song Xiaodong arrived at Bai Cui at 7: 32 pm and left at 7: 50 pm. She stayed there for 18 minutes, which is more than enough time to commit the crime, but we haven't found a clear motive yet. "
Han Bin asked, "Eighteen minutes isn't long, but it's not short either. Bai Cui Community was an old community with a small area. If it was really as Song Xiaodong said, it wouldn't have taken her so long to leave Xiao Bingtian's house after just a glance at the door. How did Song Xiaodong explain this? "
Li Qin answered, "We only checked the surveillance footage after we finished last night. Since it was quite late at that time and we had an early morning meeting today, we didn't have time to interrogate her again."
Han Bin noted it down in his notebook. "Remember to interrogate him after the meeting."
"Yes."
"Who else wants to report?"
The forensic doctor, Li Can, cleared his throat. "Captain Han, let me talk about the autopsy. Xiao Bingtian's autopsy has been completed, and there's not much difference from the initial examination. There's one thing I want to clarify, I didn't find any drug in the deceased's body. "
Han Bin confirmed, "In other words, Xiao Bingtian was conscious when he was injured."
"Yes."
Wang Xiao immediately raised a question. "If Xiao Bingtian wasn't drugged and wasn't tied up, why didn't he call for help? He's not a mute."
Jiang Yang guessed, "Could it be that he was threatened and killed if he dared to call for help?"
Wang Xiao said, "That's a possibility, but Xiao Bingtian can't be threatened forever, especially when Xiao Bingtian realized that his injury could be fatal. Would he care about the murderer's threats? Also, there should have been a period of time between Xiao Bingtian's injury and his death. The murderer couldn't have been standing by and threatening him. "
Li Qin said, "Could it be that the murderer used other things or people to threaten the deceased? Death is scary, but it's not the scariest thing. Could it be that the murderer used something that Xiao Bingtian cherished to threaten Xiao Bingtian to give up calling for help? "
Zhao Ming answered subconsciously, "For example, the photo that Captain Han saw or the person in the photo? In other words, other than the murderer, there might have been someone else present when Xiao Bingtian died. "
Han Bin listened very seriously. Two heads were better than one. The team's analysis and discussion might provide a new direction for the investigation of the case.
"Did the technical department find anything new about the crime scene?"
Ma Xiwen replied, "We collected scattered blood samples at the scene. All the blood samples collected matched the victim's DNA, and we didn't find any blood samples from a second person. We checked the fingerprints on the handle of the murder weapon, which were also the victim's. The glass cup hasn't been pieced together yet, so we can't test it further for the time being. "
Zhu Jiaxu asked, "The victim didn't commit suicide. How could there be only his fingerprints on the murder weapon? Could it be that the fruit knife that fell at the scene wasn't the murder weapon? "
Ma Xiwen shrugged his shoulders. "I think Forensic Doctor Li has more say on this point."
Li Can said, "I made a detailed comparison between the shape and size of the knife and the victim's wound. I can confirm that the knife is the murder weapon."
Zhang Shungu said subconsciously, "Could it be that the victim committed suicide?"
Wang Xiao replied, "That's impossible. If it was a suicide, how do you explain the broken glass? Why was the door open? Why did the victim ask to meet Song Xiaodong? Also, the victim's mobile phone and 80,000 yuan wouldn't have disappeared into thin air."
Wang Xiao took out a document. "I checked Xiao Bingtian's bank account. On the morning of January 31st, he did withdraw 80,000 yuan from the bank, which is the same as Xiao Guodong's statement. Based on the existing evidence, the murderer is likely to have taken the money. "
Zu Dawei said, "Could it be that the murderer deliberately erased his fingerprints on the handle of the knife and put the knife in the victim's hand to make it look like a suicide?"
He Yingsheng said, "This is unlikely. If the murderer really wanted to make it look like the victim committed suicide, he wouldn't have taken the victim's mobile phone. This is a very big loophole."
Han Bin touched his chin and followed He Yingsheng's train of thought. "According to Song Xiaodong's statement, the door of the victim's house was open. Assuming that she was telling the truth, it means that other people besides the murderer could have entered the crime scene. The person who killed Xiao Bingtian and the person who took the cash and mobile phone might not be the same person. "
Zu Dawei quickly echoed, "Yes, according to Captain Han's hypothesis, the loophole of the murderer faking a suicide scene makes sense."
He Yingsheng said, "Although this possibility exists, wouldn't it be too much of a coincidence? The moment the murderer left, the thief came in."
Zhu Jiaxu said, "Actually, it's not necessarily a thief. The door of Xiao Bingtian's house was open, and the neighbors might have seen what was going on inside. Originally, they wanted to save Xiao Bingtian, but upon closer inspection, they found out that Xiao Bingtian was dead, and there was 80,000 yuan on the coffee table. It's possible that he couldn't resist the temptation in front of him and stole the phone and money. "
Han Bin said, "I agree with Team Leader Zhu's speculation. This possibility does exist. I'm considering investigating the residents of Bai Cui Community to see if we can find any clues about the 80,000 yuan in cash. "
Zhu Jiaxu said, "If we want to investigate, I think the residents of the building where Xiao Bingtian lived are more suspicious. The residents of the other buildings shouldn't have come in for no reason. The scope of investigation has been further narrowed, but the investigation is still very difficult. We can't enter the house to search without evidence. "
"There are indeed a lot of residents in one building, but we can further narrow the scope." Han Bin took out a document. "This is the bloody footprint found at the crime scene. Through the footprint identification, I can roughly infer the physical characteristics of the owner of the footprint. He's a male, about 40 years old, thin, about 1.75 meters tall, and walks with a splayed figure."
After listening to Han Bin's introduction, Wang Xiao blurted out, "Lin Chunhua. I've made a statement for him. He's 41 years old, about 1.7 meters tall, very thin, and walks with a splayed figure. He lives in Room 402 above Xiao Bingtian's house. "
