The technical brigade subordinate to the Yuqiao City Public Security Criminal Investigation Detachment has three major departments and many small units, and its composition can be said to be intricate and huge.

The three major departments, namely the Physical Evidence Examination Department, the Trace Examination Department, and the Image Investigation Department, also have offices next to each other, on the second floor.

Qi Yuan quietly followed behind Su Ping and watched him knock on the door of the Physical Evidence Division.

After he said a few words to the inspector, he came back to his senses, looked at Qi Yuan, reported a phone number, and asked, "Is this card Duan Kun's?" ”

He quickly took out his mobile phone to confirm it, then nodded and said, "Well, this is his number, he hasn't changed it since high school, and it's been used for many years." ”

"Oh?" Su Ping glanced at him, then put on his gloves, grabbed a mobile phone, and then asked, "Then this mobile phone, is it his?" ”

"I don't know." Qi Yuan shook his head again and again: "The recent contact with him is only limited to the Internet...... But looking at the Weibo he usually posts, he should be using Xiaomi Mimix3. ”

"That's supposed to be this one." Su Ping bowed his head, and then looked at the inspector again: "You tell him about the situation." ”

"Yes!" The inspector immediately agreed, and then said to Qi Yuan: "That's right, this mobile phone was indeed found in the deceased's pocket, and the fingerprints on it also match the deceased, there is no problem."

The key is that after we unlocked the phone with the deceased's fingerprint, we conducted a detailed inspection with the help of developer tools, and found that the phone has been in the standby state of screen off in airplane mode since 1:30 noon, and there are no incoming or outgoing calls. ”

"Huh?" Qi Yuan was stunned for a moment, and hurriedly said, "This is impossible, I obviously ......"

"I know." The inspector interrupted him and said, "You called him earlier, so it stands to reason that there should be a dial-in record." ”

Qi Yuan frowned and asked, "Could it be that the murderer deleted the call log?" ”

"No, it won't." The inspector shook his head: "I just said, this phone has been in a state of screen off since noon until we unlocked the investigation, and no one has performed any operation on it, and this operation, of course, also includes deleting call logs."

We believe that the suspect probably cloned the deceased's mobile phone card in advance and switched the deceased's mobile phone to airplane mode after committing the crime, so as to replace the deceased and speak out. ”

"Clone a SIM card?" Qi Yuan asked strangely: "Didn't the operator refute the rumors before, saying that the mobile phone card chip has a high level of secrecy and cannot be cloned, and the so-called 'professional cloned mobile phone card' is just a scam?" ”

The corners of the inspector's mouth were slightly raised, and he smiled without saying a word.

Qi Yuan saw what he meant, and couldn't help but ask: "Could it be that the operator is deceiving?" ”

"It's not entirely a lie," he replied rather cautiously, "at least without the original card, it's really hard to clone out of thin air." But if there is an original card, hehe. ”

Su Ping waved his hand, asked the inspector to continue working, and left directly, as if he really came here just to let Qi Yuan identify his mobile phone and mobile phone number.

Qi Yuan was stunned, and hurriedly said, "That, senior, I'm sorry, I'll go back first." ”

The inspector nodded, signaled him to take care of himself, and he quickly ran out of the inspection room, caught up with Su Ping, and asked, "Team Su, will we go back to the meeting now?" ”

"Whatever you want."

"Huh?"

"If you want to go back, go back, and when you're tired, you can go down and rest." Su Ping replied without being salty or light.

Qi Yuan frowned slightly and said, "I'll follow you." ”

He still follows you, the frequency under his feet does not change at all, and he moves forward step by step.

Soon came to the basement floor, Qi Yuan was stunned, and asked again: "Team Su, are we going to the forensic autopsy room?" ”

Su Ping glanced at him and snorted.

Qi Yuan's face changed.

Seeing this, Su Ping finally paused, turned to look at him, sighed lightly, and said, "In our business, dealing with corpses is indispensable, if you can't stand it, give up as soon as possible."

Of course, this time the situation is special, it was your friend who died, and I didn't force you, if you can't do it, just rest, no one will force anything.

But, if you don't want to give up just like that, just give me a little bit, either calm down and watch, go to learn, or just avoid it, don't be in front of me, mother-in-law, mother-in-law, make it seem like I'm forcing you.

Finally, come with me if you can't, and go to sleep if you can't, you know? ”

"Understood!" Qi Yuan took a deep breath and nodded repeatedly: "I'll try to overcome it." ”

"Don't tell me as much as possible, it's useless, it's okay, if it doesn't work, if it doesn't work, it won't work." Su Ping snorted and said, "Let me see that egg pain again, you can go back directly." ”

After speaking, he turned around and continued to walk step by step into the depths of the aisle.

Qi Yuan took a deep breath again, suppressed all his emotions, didn't dare to show any more, and only followed quickly.

He is entangled and hesitant, it is indeed human nature, but Su Ping didn't force him to do anything, and made it clear that he couldn't stand it and went to rest, it was he who wanted to keep up, and then he was so mother-in-law, it seemed pretentious.

Soon walked to the door of the dissection room, Su Ping flicked the switch, the electronic door opened, and he walked in directly.

In the dissection room, the smell of disinfectant mixed with blood was really unpleasant, which made Qi Yuan frown, but it was only second-compared to the scene, this smell was actually much softer.

The two walked directly to the dissecting table, and Qi Yuan forced himself to stare at the corpse that had just been opened in his chest and abdomen, wanting to accept this visual impact as soon as possible.

Su Ping glanced at him, didn't say anything, then looked at the forensic doctor and asked, "Old Yan, how is it?" Is the cause of death clear or something? ”

"Almost." He replied: "There was a fatal wound on the deceased's body, located in the neck, with a total length of 17.8 centimeters, it was an incision wound, the wound was fusiform as a whole, there were no trial incision wounds on both sides of the wound angle, there was no intertissue bridge in the wound cavity, and no skin flap was seen.

The bottom of the wound is shallow on the right and deep on the left, the deepest part reaches the cervical vertebrae, and even superficial scratches can be seen at the periosteum of the vertebrae, and the trachea, esophagus and the left branch of the common carotid artery are completely severed.

However, the cause of death is more complex, and it is currently believed that hemorrhagic shock caused by arterial rupture combined with mechanical asphyxia caused by large amounts of blood drowning into the trachea, the two combined to cause the victim's rapid death.

In addition, the victim's stomach was empty, but there was still a small amount of digestive matter in the duodenum, which was identified as processed food of rice milk, as well as a small amount of minced meat and eggs, and I guess it was cheong fun, and he was killed four to five hours after the last meal.

The colleague on the other side of the physical evidence said that he had a WeChat payment at 6:15 in the morning, and the beneficiary was Chen Kee Cheong Fun Shop, which matched the food he had eaten at the last meal.

Combined with the temperature of the corpse, the degree of zombie, the state of the corpse spots, and the degree of corneal opacity, it is speculated that the time of death of the victim should be between 10 and 11 a.m.

That's probably the basic situation you get so far, are there any questions? ”
