Xun Mu shook his head and didn't say.

Su Ping didn't ask much, and continued to close his eyes to recuperate, until he arrived at the detachment, and felt the car stop in a daze, then he opened his eyes and asked, "Have you arrived?" ”

"It's here, get out of the car." Xun Mu just turned off the engine, opened the car door, and said, "If you're tired, just rest, and leave the rest of the work to me." ”

"No, you don't." Su Ping waved his hand, unbuckled his seat belt, and got out of the car.

Then the two went directly to the forensic department. Yan Zhongxin had returned with three corpses earlier, and at this time he should have come to some conclusions - of course, the autopsies of Yao Chugui and Chi Lekui were of little value, and the focus was on the cause of death of another unidentified young man.

"Team Xun, Team Su, are you two here?" Hearing the movement from the electric door, Yan Zhongxin raised his head and looked, and then said hello.

"How?"

"It can be determined that the victim died of an acute asthma attack, which led to bronchial obstruction and cardiac arrest, and eventually caused death, which is a typical 'death from disease' among the major causes of death.

In addition, I have also checked his medicine, and there is no problem with the ingredients, which can rule out the possibility that others intentionally replaced the medicine to cause his asthma attack to achieve the purpose of murder. If you can rule out the possibility that his fright was deliberately arranged by someone else, then I think you can rule out that he was killed. ”

"For now," Su Ping took over: "The possibility of setting up a bureau is very small." ”

"There's not much more to say." Yan Zhongxin said: "The conclusions that can be reached by the forensic autopsy, you all have ......"

"Wait," Xun Mu interrupted him and asked, "Where is the murder weapon?" ”

"Oh, I almost forgot." Yan Zhongxin coughed dryly twice and said: "A single-edged dagger, the blade is brand new without defects, the blade is curled, the angle of the tip is about 25 to 35 degrees, there is a blood groove, the thickness of the back of the knife is about 3.5 millimeters, the error is plus or minus 0.5 mm, the blade length is about 15 centimeters, and the error is plus or minus 1 centimeter. ”

After a pause, he glanced at the notebook on the side, looked at the data for a while, and then said: "There is also a machete, the blade length is uncertain, there are two gaps in the back, the width of the gaps is about 1.5 millimeters and 1 millimeter respectively, there is an obvious curling blade, the blade is blunt, it is estimated to be a kitchen knife." ”

After speaking, he shrugged again: "It's basically like this, it's a relatively ordinary sharp weapon, don't count on this as directional evidence, but if you lock the suspect and find a suspicious sharp weapon, you can use it for me to do an identity identification." ”

"Okay, I'll make a note of that." Xun Mu closed the notebook and said, "Then you continue to be busy, Lao Su and I will go to the trace examination department to ask." Rest early and don't fight too hard. ”

"Anla, I'm very strong." Yan Zhongxin smiled and waved his hand, and then continued to work with his head down.

Su Ping and the two glanced at each other. Without further ado, he turned around and left.

I paced to the trace examination department, asked a few questions, and learned that there was nothing to gain here for the time being, and I couldn't help but be a little disappointed.

The fingerprints found at the scene were also owned by the three victims, and no hair was found - according to the clues provided by the battery thief, the two perpetrators had shaved their heads, and no hair of the same length was found at the scene.

"Headache." Xun Mu rubbed his eyebrows and sighed lightly: "The murderer's modus operandi seems to be rough, but in fact it is quite exquisite, although we have obtained a lot of clues, but there is no one that is truly valuable, except for the video provided by the guy who stole the battery......"

"Yes, from this point of view, these two guys are actually quite professional." Su Ping pulled a chair out and sat down, pondered for a moment, and then said, "But...... A faint voice told me that there was something wrong with the car thief. ”

"Well, he's too much of a contrast, but it's a bit far-fetched to explain that he had to recruit for fear of the murderer's revenge and falling into our hands." Xun Mu also agreed, and said, "But ...... What's wrong?

Let's say he's an accomplice to the murderer...... Then there's no reason for him to just recruit those two people and provide the video directly to us, right? But if not, he has no reason to worry about this and that, and he took the initiative to shake out the matter of stealing the battery. ”

"So something is wrong." Su Ping said: "There must be a demon when things go wrong, but I really can't figure out what is going on." Wondered......"

"Report!" At this moment, Qi Yuan suddenly came over, knocked on the door, looked at Xun Mu and Su Ping, and said, "Team Xun Su, you two are really in the trace examination department......

"How?" Su Ping raised his eyebrows.

"Chi Lekui's parents are here."

"So fast?" Xun Mu immediately stood up.

"Her parents live nearby." Qi Yuan said: "Just now, the doorman passed the news, I went to bring people in......

"Let's go, then." Su Ping also stood up and said, "Go and meet." By the way, what about Yao Chugui's family? How so? ”

Qi Yuan immediately replied: "Brother Song has been informed, saying that they are also on the way, but they are relatively far away, and it may take half an hour." ”

"It's all in Yuqiao, it's good and convenient." Su Ping responded.

Soon, the three of them saw Chi Lekui's family, a middle-aged couple in their fifties, with some tears on their faces, their bodies lying on their backs, their hands together between their legs, typical restraint and self-protection actions.

The middle-aged man was a little better, and there was still a little expression on his face, and the woman's face was full of sluggishness, and her eyes were empty and out of focus, as if she couldn't stand such a big blow, and she hadn't come back to her senses so far.

"Is it Chi Lekui's family?" Su Ping asked.

The middle-aged man nodded: "Hmm." Officer, what's the situation? Who hurt my little Kui? Yao Chugui, that bastard? ”

"Yao Chugui was also killed." Xun Mu said slowly.

"Huh?" The middle-aged man was a little stunned.

"What do you call it?" Su Ping asked again.

He said: "Chi You, this surname is not easy to name, I was born in Youshi, so I am called Chi You." ”

Su Ping was not interested in why he chose this name, and only continued to ask: "Why do you suspect that Yao Chugui killed your daughter?" Have they had conflicts? ”

"Blame me, blame me." At this time, the middle-aged woman suddenly collapsed, howled and cried, and said, "Ah Kui and that bastard had a fight, that person cheated, Ah Kui wants to divorce her......

I shouldn't have persuaded her to endure it, I shouldn't have persuaded her to live her life on the same page...... If it weren't for this, if she had divorced that bastard earlier, how could she be killed by him! ”

Xun Mu clasped his hands in front of his chest, leaned back, and said, "Madam, it's not what you think, both of them were killed......

"Forget it." Chi You shook his head: "No matter what you say at this time, she won't listen to it at all." ”
