Ma Xiwen pointed to the floor and said, "These fluorescent places are full of human blood, which has been cleaned and treated, and it is difficult to see with the naked eye. ”

"Judging by the traces of blood, it must have been sprayed. ”

"There's a lot of bleeding, and if it's all from one person's blood, there's a good chance it's a major artery. ”

"I recommend having someone from the forensic department come and come up with a more detailed on-site analysis based on human characteristics. ”

Bao Xing asked, "Can these washed blood stains still detect DNA?"

"I'll try my best. ”

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

Ma Xiwen spread his hands, "The scene is very clean, and I can't find any clues except for the residual blood." ”

Ma Jingbo glanced at his watch, "Bao Xing, call the forensic department and ask them to send someone over." ”

"Han Bin, you take someone to visit the surroundings and see if there is anything you find. ”

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

"The meeting was held at half past six in the conference room of the city bureau. ”

Everyone responded and went their separate ways.

......

Han Bin led a group of people to visit the neighborhood, but the effect was not very good.

First, Niu Xin lived here for a relatively short time.

The second is that the people here are relatively mixed, and many of them are rented from other places.

Only the proprietress of the nearby commissary had 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 alone, which was basically consistent with the description of the proprietress, and bought cigarettes, alcohol, peanuts, ham, and instant noodles, and did not see any problems.

Han Bin still made a copy of the surveillance and took it back for study.

Han Bin continued to visit the surroundings, but no one else had any impression of Niu Xin.

At half past six in the afternoon, Han Bin took people back to the city bureau on time for a meeting.

In addition to the people of the Second Squadron, there was also Ding Xifeng, the captain of the Municipal Criminal Investigation Brigade.

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

"Yes. Ma Jingbo responded and beckoned everyone to a meeting.

Ding Xifeng didn't know much about the details of this case, and continued, "Captain Ma, you preside over the meeting, and I'll observe." ”

Ma Jingbo organized the language, "I will briefly introduce to you some technical and forensic departments. ”

"The technical department has extracted DNA from the bloodstains in the house, and is comparing it with Niu Xin's mother's DNA, whether the deceased is Niu Xin or not will soon have a result. ”

In addition, based on the splash marks of the bloodstains at the scene and the physiological structure of the human body, it is speculated that the victim should have had his throat cut to death, and from the angle of the fall of the bloodstains, he should have had his throat cut while standing. ”

"The victim's height should be between 1.7 and 1.82 meters. ”

And Niu Xin's height is exactly in line with this range. ”

After Ma Jingbo finished speaking, he glanced at Ding Xifeng, saw that the other party did not say, and said to the others, "Tell me about your investigation." ”

Han Bin said, "I took people to visit the Jiayuan community, because Niu Xin moved there for a relatively short time, and there are not many residents who have an impression of him. The only person who explicitly said he had seen Niu Xin was the proprietress of a nearby commissary. ”

"We called up the monitoring of the commissary, and around June 3rd, Niu Xin did go to the commissary and buy some food. He went alone and did not find his companions. ”

"We have not found any valuable clues on our side at the moment. ”

Ma Jingbo pointed to Zhu Jiaxu on the side again, "What about your group?"

Zhu Jiaxu replied, "Jiayuan Community is an old community, there is no property company, its own monitoring facilities are not complete, and it is an open community, extending in all directions, and the difficulty of investigation is a bit great." ”

"We have collected private surveillance of the shops around the community, and we have not had time to investigate it. ”

Ma Jingbo interrupted the other party, "That means that your group has no new clues now." ”

Zhu Jiaxu didn't answer, which can be regarded as a tacit acquiescence.

Ding Xifeng slammed the carbon pen on the table and said in a stern tone, "Your efficiency is not good." ”

Ma Jingbo defended, "Captain, we also found the clue this afternoon. ”

Ding Xifeng said, "What was discovered this afternoon, and the identity of the deceased has not been determined yet?"

Ma Jingbo replied, "The technical department is already comparing DNA. ”

Ding Xifeng waved his hand, "You can't take the technical test for everything, the criminal investigation team must also have the ability to judge the identity of the deceased, you don't need to have solid evidence, but you must have a spectrum in your own heart, how to investigate the next case." ”

"Ahem......"

Ma Jingbo coughed lightly, "Based on the available evidence, I speculate that the deceased should be Niu Xin, and we have already checked in this direction." ”

Ding Xifeng continued, "According to your assumption that the deceased is Niu Xin, is the time of his death confirmed?"

Zhu Jiaxu replied, "The body has not been found, so the time of death cannot be determined for the time being." ”

Ding Xifeng snorted, "When you find Niu Xin's body, the daylily is cold, there is no corpse, and the approximate time of death of the deceased can be determined through criminal investigation methods, you are all old criminal investigators, I don't need to tell you how to operate it." ”

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

"If there is no one in the house, how is it transported out? Is it a dismemberment, or is it cremation on the spot?"

"Wouldn't it be more efficient to determine the approximate time of death, determine the way to transport the body, and then compare it with video surveillance? ”

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

Ding Xifeng said a few more words about the case, and then the conversation changed, "Comrades, this was originally just a prison escape case, but as a result, the escaped fugitive died, and now the person who assisted Zhu Wei in escaping the prison is also dead, and the case is getting bigger and bigger like a snowball." ”

"The arrest warrant for Zhu Weichao has been lifted, but the murder case of Zhu Weichao has not been solved for a long time, and the truth of the case cannot be announced to the public, and the one-week deadline for solving the case is approaching soon. ”

"Look at it now, Zhu Weichao's case has not been solved, and a new case has been brought out, and another person has died. ”

"The leaders of the city bureau are very dissatisfied with this, and begin to doubt the ability of our city criminal investigation brigade to handle cases. ”

"I know that everyone has worked hard, and I know that everyone is working hard, but in the current situation, we must work harder, criminals are more cunning than we imagined, although I don't want to admit it, but from the beginning to the present, we have been led by the nose by the other party. ”

"First Zhu Weichao was killed, and now the person who assisted Zhu Weichao in prison is also dead, the mastermind behind the scenes is destroying the evidence of the crime step by step, if we want to catch him, we must go faster than him and walk in front of him. ”

"You should all understand what I said, and I don't want to repeat it a second time, in a word, solve the case as soon as possible!"
