The police car roared in, and when the police went upstairs, the landlord was still sitting on the ground, getting up with difficulty and opening the doorknob, looking decadent as "please please". Shi Yan put on protective measures and walked in front with instruments, Chen Shijie followed behind Qiao Zhen and pulled up the cordon, from now on, no one can approach this area until they finish investigating the scene and preliminarily inspect the body.

Qiao Zhen turned his head and silently examined the man on the ground. The landlord's face was pale, and the fear on his face could not be concealed or concealed. The room he was living in was outside, and a sofa bed had not yet had time to be folded. At this time, Qiao Rao just helped him up and began to question him.

She continued to walk inside, and the back room was clear at a glance, with no signs of turning or fighting. There was an ashtray at the head of the deceased's bed, in which there were also cigarette butts. At the head of the bed was a plastic comb commonly used in small hotels, on which the handwriting had been carefully sanded off. Playing cards, cigarette tissues, and empty beer bottles were scattered on the floor.

The deceased lay on his back on a single bed, his face covered with a towel, soaked with blood and hardened. When the covering was lifted, the victim's face was revealed, with a total of twenty or thirty scratches, and the murderer obviously wanted to make it difficult for people to distinguish what he looked like before his death.

Shi Yan touched the deceased's hair with her fingers, checked his scalp that had been lifted, and checked the lower corpse spots and corpse stiffness: "The fatal wound is on the head, there is no trace of resistance, he was killed in his sleep." ”

"Didn't you strangle?" Qiao Zhen pointed to the knotted rope around his neck. The shape of the knot is not an ordinary dead knot, and it looks a little complicated.

"The suffocation and scratch injuries were superimposed on top of each other, and the initial fatal injuries were on the head, and the cause of death was a head injury."

"How do you see that?" Qiao Zhen asked curiously.

"It's not about seeing it, it's about analyzing it." Shi Yeon corrected her, "You see, he has a skin laceration on his head, with a contusion of brain tissue, severe subcutaneous hemorrhage, and a depressed fracture of his skull. However, there are so many wounds of different sizes from his face to his jaw, but they are basically parallel wounds, indicating that he was already in a state of coma with no ability to resist when he was attacked, and if he was strangled, he would still have time to react, and there would be traces of resistance. As for the neck, it was a murderous action made by the murderer in order to ensure his death. ”

Qiao Zhen gave her a thumbs up: "Understood, it's really interlaced and separated from the mountains." Can you determine the time of death? ”

"When I went back to the dissection room, I looked at the contents of his stomach and judged it more accurately."

Qiao Zhen looked around, the murder weapon was missing, and the towel was confirmed to be the landlord's personal belongings, but Qiao Rao Gang obviously ruled out his suspicion of committing the crime, and firmly locked the suspicion on the other co-tenant. When he disappeared, the landlord was not aware at all.

He told the police in shock: "These two people are comrades-in-arms, and they didn't leave a mobile phone number for me, saying that they had just come to this city." ”

Zhang Chenzhi asked: "Do you know the name, how can they contact you without a mobile phone?" ”

"According to them, as soon as they got off the bus, they told me on the public phone that they wanted to rent a house. I didn't have a phone number, but I was given an ID card, and our rental contract was the person's ID card. The landlord cowered and raised his chin into the house.

"Where's the contract?"

"I'll find you here." The landlord scrambled in a locked drawer and dug through a document. Within a few minutes, Zhang Chenzhi came in from outside the house and told everyone: "It's not me, my ID card was stolen." ”

Qiao Zhen looked at the deceased on the bed, after searching just now, none of his belongings could prove his identity. So what they need to do urgently now is to determine who the anonymous deceased is, how did he come here from a foreign country, and what kind of industry is he engaged in locally?

The conference room was brightly lit that day, and the investigators of the criminal squad sent messages to their families in twos and threes, and took the initiative to stay and work overtime. At eight o'clock in the evening, when Zhang Chenzhi thought of convening everyone to hold a case analysis meeting, the internal staff easily summoned people and was busy preparing projectors and computers.

The conference room was full, and the forensic doctor Shi Yan first reported the specific situation of the deceased's victimization: "According to the autopsy, the suspect first hit his left jaw with a blunt object in his sleeping state, causing him to completely lose his ability to resist, and then used a rope to strangle his neck and cut his face with a sharp object, the cause of death was a head injury, the time of death was about three days from the incident, and according to the state and capacity of the victim's stomach contents, it was determined that the time of death was about 6 hours from the last meal." ”

"Team Joe, what do you think, tell everyone?" Zhang Chenzhi, as usual, let the master speak first.

Qiao Rao just gestured to flip to a few pictures on the periphery of the scene before: "There are no signs of hard entry at the scene, and it is more likely that an acquaintance committed a crime." In addition, the murderer deliberately painted snakes to add to the deceased's face, disrupting our investigation vision, and took away the mobile phone and all documents that may prove his identity, so it is more likely that the person involved committed the crime. We first ruled out the possibility of the landlord committing the crime, and the focus should be more on the deceased's past social relationships. ”

"As Team Qiao said, the first step we need to do in this case is to determine the true identity of the deceased, on what occasion did this person get acquainted with the victim, what kind of relationship did the two have had between them, and what motive was there for murder and robbery? It's possible that the clues are hidden in his identity. ”

"Team Zhang," Qiao Zhen raised his hand to sign, "Although the cigarettes found at the scene are Zhonghua brands that have been bought everywhere, the cigarette butts in the ashtray, combined with the tobacco and appearance characteristics, have been determined to be Yin Tao cards produced in Xiangnan City, and the playing cards left at the scene have also been identified as produced in Xiangnan, and I speculate that at least one of the victims or victims has some kind of connection with Xiangnan City." ”

Another criminal police officer interjected: "We found in our communication with the landlord that the two went to a large supermarket to purchase at the beginning of their stay, and according to the video surveillance investigation, the basic physical characteristics such as the appearance and height of the suspect were basically determined." ”

Zhang Chenzhi asked: "How is the situation of misappropriation of ID cards?" ”

"I went to see the person who registered my ID card today, and he said that the document was stolen at home half a year ago, and the suspect has not been found after reporting the case, and he does not know the screenshot of the video of the two people we showed."

Zhang Chenzhi reminded the people present: "Continue to follow up on the traces of the scene of the theft to see if you can match suspicious people or related personnel." Previously, before the two rented the house, they used a public IP phone to contact the landlord, at this point in time, confirm it again, and check whether there are any clues. ”

Qiao Rao just knocked on the table next to him, and echoed in a deep voice: "Yes, help guide the landlord to recall accurately, if the point he remembers is not wrong, this line should have material to dig up." ”

Zhang Chenzhi nodded and looked around the conference room: "In addition, do you have any additional views on the physical evidence at the scene?" ”

Everyone was silent, and they all felt that this case was purely a "headless case", and there was a debtor who was wronged, but this case was obviously not easy to handle. The silence was a bit long, everyone waited for someone to speak, and a few of the scouts muttered to each other, but they didn't want to make a public statement.

Qiao Zhen, who was flipping through the notes, didn't notice the muttering colleague, and said without hesitation: "I have." There was a comb at the scene, and the words 'so-and-so hotel' on it were worn, according to common sense, this was not a general trace, but a deliberate worn. I think this was done by the murderer on purpose. ”

"What is the purpose of grinding out the words, and what does it mean?" Someone asked.

Qiao Zhen added seriously: "If you simply rub off the handwriting and hope to erase the past traces, it makes sense for the purpose of anti-reconnaissance." But combined with a series of actions of these two people, they don't use ID cards to leave accommodation information, don't leave mobile phone numbers, don't contact outsiders, and rarely talk about themselves. Therefore, I strongly suspect that the two have criminal records, and it is even possible that they themselves are on the run. ”

Everyone nodded yes, Qiao Zhen looked at his father expectantly, he was still indifferent, and even a faint gloom between her eyebrows, she buried her head in disappointment.
