Ye Yinuo said: "I just speculate that the three direct suspects in these three cases have a very close relationship, the mandala flower was purchased by Yan Jun in Wunianguan, but it appeared in the residence of the suspect in the corpse splitting case, and we also found equipment for the purification of the medicinal liquid, that is, the scopolamine ingredient in the mandala flower was purified in the suspect's house, and the implantation of the network virus to steal my outline was also carried out from this room, and the person who did these two things, It was the person in the suspect's room who burned the hard drive. ”

"Well, this man is currently under interrogation, and he has confessed to some of the facts." Wang Han answered.

Ye Yinuo continued: "The purpose of confessing so quickly should be just to clear up the relationship, does he mean that he doesn't know anything about what the suspect did, and everything is just to do things with money?" ”

"Well, that's right, it's not like lying, let's get back to the point, the fire axe is not in the suspect's house, why is it in Yan Jun's house?" Wang Han asked directly, although what Ye Yinuo said was possible, but Wang Han also had some understanding of Ye Yinuo, what he said was possible, then it would be eight or nine to ten.

Ye Yinuo replied: "I went to the scene to check the installation date of the fire box, it has been more than five years, and I have also checked the model and specification of the fire axe, the length is sixty centimeters, this length is just enough to fit into the backpack that the suspect took away when he left." This batch of fire axes is used in parking lots, so in order to increase the weight of fire axes, the axe handle is also a steel structure, and five years is enough to make the axe handle rust to varying degrees. ”

"Yes, keep talking!"

"The murderer used a fire axe to dismember the victim, and the fire axe is not very sharp, so the murderer must be very forceful, which will have two drawbacks." Ye Yinuo paused as he spoke, observed the changes in everyone's expressions, and then continued: "First, the blood and flesh tissue cells of the deceased will definitely be left on the fire axe. Second, the rusty axe handle, when the murderer vigorously dismembered the body, will leave the skin tissue cells of the murderer's palm, and the identity of the murderer can also be locked through the DNA test of the skin shedding cells of the hand. ”

"How did you determine that the killer wasn't wearing gloves?" Dong Bingning asked in a loud voice.

Ye Yinuo replied indifferently: "The murderer is very conceited, he dares to dismember the corpse in this kind of place, judging from the contact with him from the back, it also proves this, he didn't even bring the murder weapon, so it proves that the dismemberment of the corpse is just a temporary intention, if you are a criminal, will you consider the murder weapon or gloves first?" ”

Wang Han continued: "Well, in fact, if you think about it from another angle, if the murderer was wearing gloves, there would be no need for him to take away the murder weapon, because there would be no traces of him at all." ”

Ye Yinuo nodded and said: "Yes, the murder weapon fire axe is difficult to deal with, if it is discarded at will, it will be fatal evidence if it is discovered, so hiding it at home is the safest, since it is not at the suspect's house, it is possible to be at Yan Jun's house." ”

"If you don't have it, you'll find out tomorrow morning, and if there is, the suspect can be convicted of murder." Wang Han nodded and said, and then changed his words: "Where did the deceased's head go?" Or, what was the suspect's motive for killing the victim? ”

"At this point, we can sort out the relationship between the victims and suspects in the three cases." Ye Yinuo licked his lips as he spoke, and the careful Dong Bingning handed over a bottle of water.

Ye Yinuo said thank you, took two sips and pulled over a blackboard, picked up the pen and said while writing: "326 corpse case, murderer, victim, 401 Song Keer case, Yan Jun involved in the case, the deceased Song Keer, 402 Su Lin was killed, suspect Yan Tianhua, deceased Su Lin." There are several groups of relationships that have been identified so far: first, the three suspects know each other. Second, Yan Tianhua, Song Keer, Su Lin, the three of them know each other. Third, Song Keer and Su Lin know each other, and fourth, Song Keer and Yan Jun know each other. Because the three suspects know each other, it can be determined that it was a gang that committed the crime, and it can be accurately inferred that they must have known the three deceased. ”

Ye Yinuo said something similar to a tongue twister in one breath, but everyone here understood it, that is, what needs to be determined now is the relationship between the victim of the dismemberment case, Song Ke'er and Su Lin.

"Do you think they know each other?" Wang Han asked.

Ye Yinuo nodded and said: "Absolutely, and I'm sure that the relationship between the deceased in the 326 corpse case and Song Ke'er is not ordinary, but what the specific situation is, everything will not be known until tomorrow morning, after searching Yan Jun's house." ”

Wang Han nodded and said: "Well, now Yan Jun has been confirmed guilty, but we still have to find evidence to convict Yan Jun, if Yan Jun has nothing at home, then before we find real evidence, what do we rely on to continue to detain him?" ”

"Two designations." Ye Yinuo said four words lightly.

"Two identifications? Except for Zhang Zilun who is in the view of thoughtlessness, who else? Dong Bingning asked suspiciously.

Ye Yinuo said: "At the same time that Su Lin was killed, there was a traffic accident on the road outside the manor bar, and the driver who caused the accident could identify Yan Jun. ”

"You mean the driver who caused the accident has seen Yan Jun?" Wang Han asked suspiciously, and then said: "But we have already interrogated, and the reason why the car accident happened was because he was drunk driving." ”

Ye Yinuo said: "This matter is too coincidental, it should have been arranged by Yan Jun in advance." ”

"How is this possible? Impartial, just outside the Manor Bar in a car accident? And the result of our interrogation was that he was indeed in a car accident caused by drinking, and the blood test result was also excessive alcohol content. Wang Han asked.

Ye Yinuo asked: "Is there too much exceedance?" ”

"Not much, only 75mg/100ml, not even the standard for drunk driving, it stands to reason that there will not be such a big accident." Wang Han said.

"This is the suspicion, and only to this extent did he dare to go on the road, and in a specific place, a specific situation should have occurred, which led to a traffic accident, which is likely to be related to the direct consumption of scopolamine." Ye Yinuo said.

"Scopolamine again, how many people have been harmed by that magic stick." Dong Bingning said.

Ye Yinuo smiled and explained: "Scopolamine can paralyze people's thinking, make people's reaction speed slower, and under the catalysis of alcohol, it can even make people hallucinate, and from the mandala petals found from the suspect's house, it should only be a total of more than a dozen, Zhang Zilun said that Yan Jun bought two hundred flowers from him, in addition to the fifty or so flowers used on Song Keer's body, and the bottle of things in the car that kidnapped me and Tang Nianyou, the others should be used by Yan Jun on the driver who caused the accident." ”

Wang Han nodded and said, "By the way, the composition of scopolamine has been detected in that bottle, even if it is a full bottle, it is only about eighty flowers." ”

"Where's the fingerprint information on it?" Ye Yinuo asked.

Dong Bingning continued: "There are three groups of fingerprints, yours, the suspect, and one group is being identified, but it is not Yan Jun's, it is very likely that it is Wu Dongsheng's." ”

"Wu Dongsheng?"

"It's the same accomplice who lives with the suspect, and he's been detained." Dong Bingning replied.

Ye Yinuo thought for a while and said: "As for the whereabouts of the head, if it is not in Yan Jun's house, it will be dealt with, and all the facts of the case have almost been analyzed, Team Wang, I will hand it over to you." ”

Wang Han nodded and said: "Okay, thank you, it's really a vivid lesson, everyone has worked hard today, those who should work overtime stay and work overtime, and the others go back to rest early, stand by at any time, and the heads of various departments will arrange the work." ”

After Wang Han finished speaking, everyone stood up, few went home, and most of them returned to their seats, although the case was simple, but a lot of materials and materials needed a lot of time to sort out.

Wang Han raised his hand and looked at his watch, it was almost two o'clock in the morning.

He was still full of energy and said: "Ye Yinuo, I'm really sorry, are you sleepy?" If you're not sleepy, would you like to have a late-night snack? ”

Ye Yinuo naturally knew that Wang Han still had something to do with him, but now it was very late, and it was time in another hour, so he had to go back home to rest.

Ye Yinuo shook his head and said, "I'm very sleepy, just eat supper, Team Wang, I know what you want to ask, I don't have a clue now." ”

What Ye Yinuo said is naturally the leaker's matter, but who that person is, Ye Yinuo is not sure, he has an object of suspicion, that is, the second fat in the forensic office, but he has no evidence, this kind of matter involving the political position of the police officer, he Ye Yinuo does not dare to make a conclusion.

Wang Han smiled and said, "Do you have no clue, or don't you dare to say it?" ”

Ye Yinuo smiled, shook his head, and turned around and walked towards the door.

"Xiaoice, you send Ye Yinuo home."

"No, I'll just call a car." Ye Yinuo said.

Wang Han smiled and said: "That's okay, you are such a big hero, and you have no pay, and you still let you take a taxi by yourself, then our Xicheng detachment is too inhuman." ”

Ye Yinuo smiled, he knew that Wang Han did not doubt his dedication to solving the case, but he was still worried that he had other secrets, after all, he Ye Yinuo was too unusual.

"Ye Yinuo, I'll send you." Dong Bingning walked over and went out with Ye Yinuo, and she also vaguely knew what Wang Han meant.

As soon as Dong Bingning went out, Wang Han took out his mobile phone and sent a message to Dong Bingning: "You will live in Ye Yinuo's house tonight to "protect" his safety." ”

The word protection, Wang Han added a double quotation mark to the snake, and the meaning is self-evident.

Dong Bingning walked to the side of the car, her mobile phone rang, and she glanced at the message.

Dong Bingning's heart is a little helpless, and only this kind of work will have such an arrangement, she Dong Bingning is still a yellow flower girl, staying at a man's house late at night, it is not good to say.

However, the uniform on her body gave her a little sense of security, and she didn't hate Ye Yinuo as a person, and she also believed in him as a person, so Dong Bingning didn't have much resistance.

Sitting in the car, Dong Bingning took the initiative to say: "Now is the critical period for the investigation of the case, and I will protect you before the case is closed." ”

"You mean you're going to stay in my house tonight?" Ye Yinuo was stunned for a moment and asked suspiciously.

"Yes!"

"No way!" Ye Yinuo decisively rejected Dong Bingning's request, he knew very well that he couldn't be disturbed when he had a phobia, once he was disturbed, then he would have a messy day in the next day, and his thinking would become very dull, as if he had changed someone, this kind of thing, at such a critical moment, Ye Yinuo would never allow it to happen.
