"He died between 10 and 11 o'clock, and the fatal wound was a cut to the neck." Su Ping nodded clearly, and asked again: "Does the deceased have signs of poisoning, or resistance injuries, restraint injuries or something?" ”

"None of them." Lao Yan shook his head: "There is no coma, no poisoning, no restraint injuries."

In addition, the nails of his ten fingers were carefully scraped by the murderer with a knife, I guess it was the moment he was stabbed, he instinctively struggled to resist and scratched the murderer's skin, the murderer was worried that we would extract DNA from the dander tissue, so he carefully scraped it off. From this point of view, his sense of anti-investigation is quite strong. ”

Su Ping thoughtfully, glanced at Qi Yuan, and asked, "What do you think?" ”

Qi Yuan's gaze finally moved away from the corpse, and he forcibly suppressed his unbearable color, and said with a straight face: "Team Su, this must be an acquaintance who committed the crime. ”

Su Ping raised his chin and asked him to unfold it and say it well.

He organized the language a little and said, "First of all, sound. The suspect disguised himself as Duan Kun and played games with me normally. Regardless of what his motives were, being able to imitate them to this extent showed that he had enough understanding of Duan Kun, at least Duan Kun's voice, and had deliberately practiced it. ”

Su Ping did not say anything, only motioned for him to continue.

He hummed and continued, "The second is the mobile phone card." The colleague who just gave physical evidence said that his mobile phone card was suspected to be cloned, so I would call him. And this kind of clone requires the original card, otherwise the difficulty will undoubtedly increase a lot, and it is almost impossible to do.

Of course, it may also be that his mobile phone was lost and fell into the hands of the suspect, but I think that since it is a clone, it means that all the information of the original card has been moved, so if Duan Kun reports the loss afterwards, the mobile phone card cloned by the suspect will naturally be useless.

So I think he must have gotten the mobile phone card for some reason, without arousing Duan Kun's suspicions, and then quickly proceeded to Kelong. To do this, of course, you can only be acquaintances. ”

Su Pingjian frowned, nodded slightly, and asked, "What else?" ”

When Qi Yuan saw it, he was a little excited, and said, "In the end, it was the injury on his body." Director Gang Tu said that the murderer committed the crime behind the deceased, and there was no medicine to stun the deceased, nor did he restrain him, and I also watched the scene, and the victim was lying on the counter after he died.

This shows that Duan Kun has a considerable degree of trust in him, at least, the suspect can enter and exit the counter fairly freely, and Duan Kun will not be too guarded. In this way, he has the conditions to storm the killer and stab him in the back.

In addition, the cut is shallow on the right and deep on the left, indicating that the direction of the cut is from right to left, and if the murderer stabbed the deceased in the back, it is likely that he was holding the knife in his left hand, in other words, he was left-handed.

It just so happened that when I analyzed his gait through footprints at the scene, I found that when the suspect walked and stood normally, his supporting leg was also his left leg, indicating that his usual hands and feet were on the left side, and he was completely left-handed. ”

Su Ping nodded again, his face was much gentler, and asked, "Then what characteristics do you think the murderer has besides the fact that the murderer is likely to be an acquaintance of the deceased?" ”

"This ......" Qi Yuan thought seriously for a while before he said: "He is likely to be engaged in electronic maintenance-related work, so that he has enough conditions to obtain his mobile phone and mobile phone card without Duan Kun's defense, and can easily carry out Kelong on the mobile phone card."

In addition, Duan Kun's Steam account should have been stolen by him by hacking, after all, people now habitually set a large number of software account passwords to the same, and it stands to reason that they will not easily tell others.

If the game account alone is not enough to explain the matter, then, it is impossible for him to tell the murderer on the WeChat account, right? And although it is not difficult to steal the number, not everyone can do it, so I think the suspect's occupation should be related to it.

Acquainted with the deceased, left-handed, sound and image, engaged in mobile phones or computers and other related electronic industries...... If my speculation is correct, I think the range is small enough. ”

After speaking, he looked at Su Ping blankly, waiting for him to evaluate.

"Not bad." Su Ping nodded slightly: "You can calm down and use your brain." ”

His face was bitter, and Su Ping gave a rare affirmative response, just because he calmed down.

But it's right to think about it, his inferences are actually very shallow, just a simple guess based on existing clues, and it's normal that he can't get into Su Ping's eyes.

On the contrary, Lao Yan, who had been silent for a long time, couldn't stand it anymore, he glanced at Su Ping: "You have it, I look at the little guy quite well, at least better than when you just graduated." You know, at that time, you couldn't even memorize the endorsement, and you were trained by the old man all day long......"

Su Ping rolled his eyes, too lazy to take care of him.

Qi Yuan turned his head slightly and pursed his lips, indicating that he hadn't heard anything......

Seeing that they didn't say anything, Lao Yan couldn't help but wave his hand and began to drive people away: "Come on, if it's okay, you guys should leave quickly, my autopsy here is not finished yet." ”

When Qi Yuan heard this, he was a little puzzled: "Director Tu, aren't the cause of death and the time of death clear?" What else to do? ”

"Confirm the above speculation and rule out other possibilities." Lao Yan is old and quite easy-going, so he immediately explained:

"The cranial cavity, the thoracic cavity and the abdominal cavity must be systematically and carefully examined.

If nothing else, what if the victim has some hidden chronic disease? For example, chronic alcoholism, which requires a blood test at the same time, to smell his liver for acetaldehyde, and to take a tissue section.

Only after all other possibilities have been ruled out can the resulting report be effective, right? ”

Qi Yuan nodded slightly, and then looked at Su Ping.

He was silent for a short time before he said, "Then I won't bother you." Well, what's new, give me a call. ”

"Gotcha."

Seeing this, he nodded, glanced at Qi Yuan, and walked out of the dissection room.

"Tomorrow you follow Komatsu." After walking a few steps, Su Ping suddenly said: "He is responsible for visiting the relatives and friends of the deceased, and I will ask him to arrange the corresponding tasks for you." ”

Qi Yuan nodded, and then asked, "What about you from Team Su?" ”

Su Ping didn't answer, just glanced at him.

Seeing this, he immediately changed his tune and said, "No problem, I'll do it well." ”

"Hmm." He nodded and asked, "What do you want to eat?" ”

"Huh?" Qi Yuan hesitated for a while: "Don't you go back to the meeting?" ”

"I already know about the trace examination, and the forensic doctor and the physical evidence have just been seen separately, and the on-site visit will obviously not find anything, otherwise they will say on the spot, what are you going to do? Besides, it's estimated that it's over at this point, just ask Komatsu to tell me. In this way, you give Komatsu a call, let's go out for a bite to eat. ”

"But ......"

"How did you mother-in-law?" Su Ping paused: "But what?" ”

"I don't have Brother Song's phone ......"
