According to Han Bin's speculation, the two cases should be related. Even the murderer who killed Jin Zhiwen is likely to be the same person who killed Dong Yubei.

The murder of Dong Yubei has reached a dead end, and no new breakthrough has been found, and the murder of Jin Zhiwen has pointed out a new direction for Han Bin's investigation.

Han Bin told Zeng Ping of his speculation, and at the same time put forward the idea of setting up a joint investigation team for the Wuhua Mountain case.

Zeng Ping has no opinion on this, he and Han Bin cooperate tacitly, and there is no problem. Taking a step back, even if they have opinions, they can't compete with the city bureau.

Subsequently, Han Bin reported to the captain of the brigade, Ding Xifeng, and learned that the murderers in the two cases were likely to be related, and Ding Xifeng immediately agreed to the proposal to set up a special joint investigation team.

He has also been paying attention to this case, and he has not been able to find a breakthrough in the case for a long time, and he is also in a hurry.

With the support of Ding Xifeng, Han Bin joined the investigation of the case with people from the Second Squadron of the Municipal Criminal Investigation Brigade.

When Jin Zhiwen went to the police station to testify, Zhu Jiaxu investigated his surrounding relations, and the people in the second squadron were no strangers to Jin Zhiwen's situation.

After Liu Yanni's mood stabilized, Han Bin spoke, "Ms. Liu, I can understand your current mood, but the current situation is special, and we need your assistance to solve the case as soon as possible and get justice for Jin Zhiwen." ”

Liu Yanni wiped her eyes, "Comrade policeman, what do you want me to do?"

"You should have seen the camera equipment that Jin Zhiwen often uses. ”

"I know that. ”

"Can you describe what camera equipment he has?"

"He has a camera, a small video camera, and a tablet, and he usually takes those three with him when he goes out to do the work. ”

Zhu Jiaxu said, "When I met Jin Zhiwen in Wuhuashan, he only carried a camera and a tablet, and he had never seen a small video camera. ”

Han Bin looked at Zeng Ping, "Team Zeng, did you find a small camera at the scene?"

"Nope. ”

Han Bin looked at Liu Yanni and asked, "Ms. Liu, can you describe the brand and style of the camera?"

"It's a foreign brand, it's all in English, and I don't know what it's called. The color of the camera is black. Jin Zhiwen is usually very babyy, and even I won't be allowed to move. ”

Han Bin patted Li Hui on the shoulder, "You take someone to search carefully, if there is a manual or warranty card for a small camera." ”

Liu Yanni couldn't recognize the brand, so Han Bin could only find clues to determine the brand of the camera by himself.

Han Bin continued to arrange, "Team Leader Zhu, you know more about Jin Zhiwen's situation, you go to investigate whether Jin Zhiwen's photo has won an award, and whether there is really a big boss he said." ”

"Yes. Zhu Jiaxu answered, called a few people and left the scene.

The technical team and the forensic doctor are also almost busy.

Lu Wen of the technical team walked over and greeted, "Team Zeng, Team Han, the scene has been surveyed." ”

"What did you find?"

"Some fingerprints and hairs were collected from the scene, and we need to bring them back for identification." In addition, we also found a group of bloody footprints at the scene, this Korean team is an expert, and when I take it back and deal with it, I will send a clear shoe print photo to the Korean team.

In addition, judging from the traces of blood splattering and dripping at the scene, the victim should have been stabbed at the door of the bedroom first, and then turned around and fled back to the bedroom and fell on the bed, forming the scene like this.

We also took out a towel from the deceased's mouth, which was supposed to be used by the killer to prevent the victim from crying out. That's all we have found so far. ”

Han Bin said, "I've worked hard, waiting for your appraisal results." ”

“OK。 Lu Wen greeted and packed his toolbox.

After Jin Zhiwen's body was put into a body bag, Wu Xia also came over and took off her gloves and mask, "Huh, I'm finally done, I don't know what happened in the recent period, there are obviously more homicides than before." ”

Zeng Ping said, "As soon as the epidemic passed, many people lost their jobs, and social conflicts increased. People are prone to accidents when they are impulsive, and it should be fine next year. ”

"Hopefully. ”

Wu Xia responded and continued, "I have completed the preliminary time, the cause of death of the deceased is just like you can see, he was stabbed once in the chest, five stabs in the back, the fatal wound was pierced into the lungs from behind, plus excessive blood loss caused hypoxic shock and died.

The time of death was between half past eight and eleven last night, and the murder weapon was a sharp knife with a blade seven to ten centimeters long. As for the detailed autopsy report, it needs to be further identified after returning to the precinct. ”

After Wu Xia finished speaking, she instructed the police to carry the body bag onto the stretcher and transport it down from the elevator.

After Han Bin listened, he instructed Wang Xiao on the side, "You visit the neighbors around you and ask if they heard any unusual sounds between eight and eleven o'clock last night." ”

According to forensic doctor Wu Xia, the time of Jin Zhiwen's death was between half past eight and eleven o'clock last night, and the time of injury must have been earlier, considering that Jin Zhiwen's injuries were serious and could not last long, Han Bin pushed the suspect forward the time of committing the crime by half an hour.

"Da ......" A heavy footstep sounded, and Sun Xiaopeng walked into the living room.

When Sun Xiaopeng was about to report to Zeng Ping, he suddenly looked at Han Bin in surprise, "Team Han, why are you here?"

Han Bin smiled, "I was still thinking just now, where did you kid go, why haven't you seen him all this time." ”

"Hehe, Team Zeng told me to check the surveillance. Sun Xiaopeng laughed and reported, "Team Zeng, Team Han, I went to the property company to check the monitoring, and found that at about 9:35 last night, a suspicious person took the elevator to this floor, and left by elevator at about 9:42. ”

Li Hui asked, "Is it the owner of this building?"

Sun Xiaopeng shook his head, "I don't know." ”

"The property company doesn't know either?"

"Team leader, just look at the surveillance. Sun Xiaopeng took out his tablet and played a surveillance video, which should be a video of the inside of the elevator from the screen.

At 9:35, the elevator door opened, and a person got on the elevator, this person was dressed very tightly, wearing a hat on his head, a mask on his mouth, a black coat on his body, and a black backpack behind him, judging from the style of clothes, he looked like a man.

Zhao Ming leaned over and took a look, "This is too tightly dressed, I have a ghost in my heart when I see it." ”

Tian Li retorted, "It's not necessarily, it's winter now, and many people wear masks and hats when they go out, which is very common on the street." ”

Zhao Ming laughed and didn't speak.

Bao Xing took a closer look and shook his head, "It's so tightly wrapped that I haven't even taken a picture of my face, and I can't catch anyone with surveillance." ”

Han Bin also felt that this person was a little suspicious, not only because of his clothes, but also because of the timing of his appearance, since he had been near the scene during the time period of the crime, he naturally had to investigate.

"Check the surveillance around the neighborhood and continue to track this person's whereabouts......"
