Chapter 602

Ma Xiwen pointed to the floor and said, "these fluorescent places are human blood. After cleaning and treatment, it's hard to see them with naked eyes."

"From the traces of blood, it should have been sprayed."

"There's a lot of bleeding. If it's all a person's blood, it's likely that the main artery was injured."

"I suggest we invite people from forensic medicine to come here. They can make a more detailed on-the-spot analysis based on human characteristics."

Bao Xing asked, "can these cleaned bloodstains detect DNA?"

"I'll try."

Ma Jingbo asked, "are there any other discoveries?"

Ma Xiwen spread out his hand, "the scene was cleaned very clean, and there was no other clue except the residual blood."

Ma Jingbo took a look at his watch. "Bao Xing, call legal medicine and ask them to send someone over."

"Han Bin, you take people to visit around to see if you find anything."

"Zhu Jiaxu, you take people to collect the surrounding surveillance."

"It's six thirty in the Council room."

Everyone responded and acted separately.

……

Han Bin with a group of people in the vicinity of the visit, but the effect is not very good.

First, Niu Xin lived here for a short time.

Second, the staff here are quite miscellaneous, many of them are from other places.

Only the landlady of the nearby canteen has an impression of Niu Xin.

According to her, Niu Xin came to his store to buy things.

Han Bin asked her to call up the monitoring at that time. Niu Xin came by himself, which was basically consistent with the description of the landlady. He bought cigarettes, wine, peanuts, ham and instant noodles, but he didn't see any problems.

Han Bin still copied a copy of the monitoring and took it back for research.

Han Bin continued to visit around, but others had no impression of Niu Xin.

At 6:30 p.m., Han Bin took people back to the Municipal Bureau on time for a meeting.

In addition to the second squadron, Ding Xifeng, leader of the municipal Criminal Investigation Brigade, attended the meeting.

Ding Xifeng saw that the people came almost, and said with a straight face, "Captain Ma, let's have a meeting."

"Yes." Ma Jingbo answered and called for a meeting.

Ding Xifeng didn't know much about the details of the case. He continued, "Captain Ma, you can preside over the meeting. I'll listen in."

Ma Jingbo organized the language, "to briefly introduce some technical departments and legal medicine."

"The technology department has extracted DNA from the bloodstain in the room, and is comparing it with Niu Xin's mother's DNA. Whether the dead Niu Xin will have a result soon."

"In addition, according to the splashing traces of blood on the scene and the physiological structure of the human body, it is speculated that the victim should have been cut throat and died. From the perspective of blood fall, the victim should have been cut throat standing."

"The height of the victim should be between 1.7 and 1.82 meters."

"And Niu Xin's height is just in line with this range."

After Ma Jingbo finished, he took a look at Ding Xifeng and saw that the other party didn't say anything. He said to others, "tell me about your investigation."

Han Bin said, "I took people to visit Jiayuan community, because Niu Xin moved there for a short time, and there were not many residents who had an impression on him. The only person who has made it clear that he has met Niu Xin is the landlady of the nearby canteen. "

"We transferred the monitoring of the store. Around June 3, Niu Xin did go to the store and bought some food. At that time, he went alone and did not find his companion's whereabouts. "

"We haven't found any valuable clues yet."

Ma Jingbo pointed to the side of Zhu Jiaxu, "what about your group?"

Zhu Jiaxu replied, "Jiayuan community is an old community, there is no property company, its monitoring facilities are not complete, and it is an open community, extending in all directions, so it is difficult to investigate."

"We have collected the private monitoring of shops around the community, and we haven't had time to check."

Ma Jingbo interrupted the other side, "that is to say, your group has no new clue now."

Zhu Jiaxu didn't answer, so he was acquiescent.

Ding Xifeng threw the carbon pen on the table, and said sternly, "your efficiency is not good."

Ma Jingbo explained, "Captain, we only found the clue this afternoon."

Ding Xifeng said, "I found it this afternoon. I haven't determined the identity of the dead yet?"

Ma Jingbo replied, "the technology department is already comparing DNA."

Ding Xifeng waved his hand, "you can't test the technology department for everything. The criminal investigation team should also have the ability to judge the identity of the dead. You don't need to have solid evidence, but you have to have a spectrum in your heart. How to investigate the next case."

"Cough..."

Ma Jingbo coughed softly. "According to the existing evidence, I guess the dead should be Niu Xin. Moreover, we have checked in this direction again."

Ding Xifeng then said, "according to your hypothesis, the deceased is Niu Xin. Has the time of his death been determined?"Zhu Jiaxu replied, "the body has not been found, so the time of death can not be determined for the time being."

Ding Xifeng snorted, "when you find Niu Xin's body, the cauliflower is cold. If there is no body, you can also determine the approximate time of death by means of criminal investigation. You are all old criminal investigators. I don't need to tell you how to operate."

"Also, if Niu Xin was killed in the house, where is the body now?"

"If it's not in the house, how is it transported out? Is it dismembered or cremated on the spot? "

"Determine the approximate time of death, determine the way to transport the body, and then compare with video surveillance, whether the efficiency will be a little higher."

Seeing that Ding Xifeng was very angry today, Ma Jingbo didn't dare to answer again. He just listened quietly

Ding Xifeng said a few more words about the case, and then the story changed, "comrades, this was just a case of prison break. As a result, the escaped prisoner died. Now the person who helped Zhu Weichao escape also died. The case is snowballing."

"The arrest warrant for Zhu Weichao has been lifted, but the case of Zhu Weichao's murder can not be solved for a long time, and the truth of the case can not be disclosed to the public. The time limit of one week is coming."

"Look at the present, Zhu Weichao's case has not been solved, and a new case has been brought out. He is dead again."

"The leaders of the Municipal Bureau are very dissatisfied with this. They begin to doubt the ability of the Criminal Investigation Brigade in our city. It's a small matter for me to be scolded, but the face of the Criminal Investigation Brigade in Qindao city can't be lost."

"I know that we have worked hard and hard, but now we have to work harder. Criminals are more cunning than we think. Although I don't want to admit it, we have been led by each other's nose since the beginning."

"First Zhu Weichao was killed, and now the person who helped Zhu Weichao escape is dead. The behind the scenes agent is destroying the criminal evidence step by step. If we want to catch him, we must go faster than him and get ahead of him."

"You should understand what I said, and I don't want to repeat it again. In a word, solve the case as soon as possible!"
