Ma Xiwen pointed to the floor and said, "These fluorescent areas are human blood that has been washed and processed. It's hard to see with the naked eye."
"Judging from the traces of blood, it should have been sprayed."
"There's a lot of blood loss. If this is the same person's blood, then it's likely that the main artery was injured."
"I suggest that we ask the forensic department to come over. They can combine human characteristics to make a more detailed analysis of the scene."
Bao Xing asked, "Can the cleaned blood still be tested for DNA?"
"I'll try my best."
Ma Jingbo asked, "Did you find anything else?"
Ma Xiwen spread out his hands. "The scene was cleaned very well. Other than the residual blood, we can't find any other clues."
Ma Jingbo glanced at his watch. "Bao Xing, call the forensic department and ask them to send someone over."
"Han Bin, bring some people to look around and see if there's anything."
"Zhu Jiaxu, bring some people to collect the surrounding surveillance footage."
"We'll have a meeting at the municipal bureau's conference room at 6: 30."
Everyone responded and split up to carry out their tasks.
…
Han Bin brought a group of people to look around, but the results were not very good.
First, Niu Xin had only lived here for a short time.
Second, the people here were quite mixed. Many of them were renting houses from other places.
Only the lady boss of the nearby snack bar had an impression of Niu Xin.
According to her, Niu Xin had come to her shop to buy something.
Han Bin asked her to check the surveillance footage. Niu Xin came alone, which basically matched the lady boss's description. He bought cigarettes, alcohol, peanuts, ham, and instant noodles. There was no problem.
Han Bin still made a copy of the surveillance footage and took it back to study.
Han Bin continued to look around, but the others had no impression of Niu Xin.
At 6: 30 pm, Han Bin brought his people back to the municipal bureau for a meeting.
Other than the people from Squadron Two, the captain of the municipal criminal investigation team, Ding Xifeng, also attended the meeting.
When Ding Xifeng saw that almost everyone had arrived, he said with a straight face, "Captain Ma, let's start the meeting."
"Yes." Ma Jingbo responded and called for everyone to start the meeting.
Ding Xifeng didn't know much about the details of the case, so he continued, "Captain Ma, you host the meeting. I'll sit in."
Ma Jingbo organized his words and said, "Let me briefly introduce the situation of the technical department and forensic science department."
"The technical department has already extracted DNA from the blood stains in the house and is currently comparing it with Niu Xin's mother's DNA. We will soon know whether the victim is Niu Xin or not."
"In addition, according to the blood splatter and the physiological structure of the human body, the victim should have died from having his throat slit. Judging from the angle of the blood, he should have been standing when his throat was slit."
"The victim's height should be between 1.7 to 1.82 meters."
"And Niu Xin's height is in this range."
After Ma Jingbo finished speaking, he glanced at Ding Xifeng. Seeing that he did not respond, he said to the others, "Tell me about your investigation."
Han Bin said, "I brought some people to visit the Jiayuan District. Since Niu Xin moved there recently, there aren't many residents who have an impression of him. The only person who clearly said that she had seen Niu Xin was the lady boss of the nearby snack bar. "
"We retrieved the surveillance footage from the store. Around June 3rd, Niu Xin did go to the store and buy some food. At that time, he went alone and did not find the whereabouts of his companions. "
"We haven't found any valuable clues on our side so far."
Ma Jingbo then pointed to Zhu Jiaxu. "What about your team?"
Zhu Jiaxu replied, "Jiayuan District is an old district. There is no property management company, and the surveillance facilities are not complete. Also, it is an open district that extends in all directions, so the investigation is a little difficult."
"We have collected private surveillance footage from the shops around the district, but we haven't had time to conduct an investigation."
Ma Jingbo interrupted him. "That means your team has no new clues now."
Zhu Jiaxu did not answer, which was a tacit agreement.
Ding Xifeng threw the carbon pen on the table and said sternly, "Your efficiency isn't good."
Ma Jingbo argued, "Captain, we only found the clues this afternoon."
Ding Xifeng said, "We found it this afternoon, and you still haven't confirmed the identity of the victim?"
Ma Jingbo replied, "The technical department is already comparing the DNA."
Ding Xifeng waved his hand. "You can't test the technical department for everything. The criminal investigation team also needs to be able to determine the identity of the victim. We don't need you to have solid evidence, but you need to have a plan in your heart about how to investigate the next case."
"Ahem …"
Ma Jingbo coughed softly. "According to the current evidence, I speculate that the victim should be Niu Xin, and we are already investigating in this direction."
Ding Xifeng continued, "According to your hypothesis, the victim is Niu Xin. Has his time of death been confirmed?"
Zhu Jiaxu replied, "The body hasn't been found, so the time of death can't be determined for now."
Ding Xifeng snorted. "By the time you find Niu Xin's body, it will be too late. Even without the body, we can still determine the approximate time of death through criminal investigation methods. You are all experienced criminal investigators, so I don't need to tell you how to do it, right?"
"Also, if Niu Xin was killed in the house, where is the body now?"
"If it's not in the house, how was it transported out? Was it dismembered or cremated on the spot? "
"Determine the approximate time of death, determine the method of transporting the body, and then compare it with the video surveillance. Will it be more efficient?"
Seeing that Ding Xifeng was very angry today, Ma Jingbo didn't dare to answer and just listened quietly …
Ding Xifeng said a few more words about the case, then changed the topic. "Comrades, this was originally just a prison break case, but the escaped prisoner is dead. Now, the person who helped Zhu Weichao escape is also dead. The case is like a snowball that is getting bigger and bigger."
"The arrest warrant for Zhu Weichao has been lifted, but Zhu Weichao's murder case has not been solved, and the truth of the case can't be revealed to the public. The one-week deadline for solving the case is coming soon."
"Look at now, Zhu Weichao's case hasn't been solved yet, but a new case has appeared, and another person has died."
"The leaders of the municipal bureau are very dissatisfied with this, and they are beginning to doubt the ability of our city's criminal investigation team to handle cases. It's a small matter that I'm being scolded, but we can't lose the face of our city's criminal investigation team."
"I know that everyone is working very hard, and I know that everyone is working very hard, but in the current situation, we must work harder. Criminals are more cunning than we thought. Although I don't want to admit it, we have been led by the nose from the beginning until now."
"First, Zhu Weichao was killed, and now the person who helped Zhu Weichao escape from prison is also dead. The mastermind behind this is destroying the criminal evidence step by step. If we want to catch him, we must be faster than him and walk ahead of him."
"You should all understand what I'm saying, and I don't want to repeat it again. In short, solve the case as soon as possible!"
