Zhang Mengqi stood next to Zhang Mengjiao, and vaguely heard Lao Xian's magnetic voice:

"The blood sample was matched, and the ** in the deceased's body was Wu Jun's. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ”

Zhang Mengjiao hung up the phone and came with confidence:

"It's a man, if you do it, you do it, if you don't do it, you don't do it, what is there to hide. What the hell happened to you two last night? ”

"I ......"

"Now that everyone is dead, you still don't want to tell the truth? How long will it be hidden? Did the two of you ever have sex? Zhang Mengjiao was straightforward.

"Happen, happen, happen." Wu Jun's face flushed, glanced at Zhang Mengjiao, who was typing on the keyboard in front of the computer, and replied a little embarrassed.

"Aren't you divorced? Still in contact? Zhang Mengjiao asked with squinted eyes.

"I ......"

Seeing him procrastinating like this, Zhang Mengjiao slapped the table and shouted: "Tell me what happened that night carefully!" ”

Wu Jun was really frightened by this move, and hurriedly opened his mouth to answer:

"At about nine o'clock last night, I received a call from Wang Yan, who said that she was not feeling well and asked me to go and see her. I was so worried that I ran back. Unexpectedly, as soon as I pushed the door into the house, Wang Yan hugged me and kept kissing me on the mouth. I'm a normal man, and in the face of the woman I love so actively, I couldn't control it for a while, and I had a relationship with her in the house. ”

"How many times have you had a relationship?"

"Two ...... Twice. ”

"Go on."

"After having a relationship, we first took a shower, and then cleaned the house as before, and after the busy work, Wang Yan said the real purpose of calling me over this time."

"The real purpose?"

"She said that although we are divorced, her heart will always be with me, last night happened to be her ovulation period, she was going to give me a child, and when the child is ripe, the man named Li Da will naturally leave her, and her mother will not bear to see the child without a father, and she will never break up the two of us again."

"I know Wang Yan's good intentions, but I am a man, and in the end I need the person I love the most to use such means to save this relationship, I really feel that I am living a very humble life. Hearing her say that, I didn't linger too much at home because I wanted to be alone. ”

"What time did you leave home?"

"It's about twelve o'clock."

"Where did you go after you left home?"

"I bought two bottles of liquor at the commissary and went to the river."

"You've been there all night?"

"I got drunk last night and fell asleep on a wooden chair by the river until about eleven o'clock in the morning when the police found me and brought me here."

After listening to this, Zhang Mengjiao got up and said, "Okay, let's talk about it here today." ”

"Mengjiao, take Wu Jun to the scout's office to take care of it for a while, and then make a decision after Guoxian's result analysis is over."

"Got it."

"You print out two copies of the interrogation materials, one for the record, and the other for us to take away."

"Okay."

After doing all this, it was already half past one o'noon, and we simply grabbed two mouthfuls of lunch in the criminal police team, and then rushed to our department without stopping.

As soon as Zhang Mengqi got out of the car, he went headlong into Lao Xian's laboratory.

"Guoxian, how's it going? Have all the on-site samples been analyzed? ”

"That's it!" Lao Xian's printer was running at a rapid pace, and the blank A4 paper was printed with many patterns and words marked with data.

"I'll be waiting for you in the conference room."

A few minutes later, all the members of our department were seated. Zhang Mengqi motioned for Zhang Mengjiao to hand Wu Jun's interrogation materials to Xiao Jiao and Lao Xian. When the two of them had finished reading, he flipped through his notebook.

"Let's analyze whether this Wu Jun can rule out suspicion"

According to the order of the on-site investigation, Zhang Mengjiao was the first technician to enter the scene, first introduced the situation of the trace inspection, Zhang Mengjiao thought about it a little, and then said:

"Let me first talk about the fingerprints at the scene, I also did a lot of analysis in the room at that time, the suspect was wearing latex gloves to commit the crime, and I did find Wu Jun's fingerprints on the door of the crime scene, indicating that he was not wearing gloves when he entered the room."

"The second is the shoe print, the suspect is wearing spikes, I carefully compared them on the Internet, because the spikes of the spikes do not have a fixed installation method, so it is impossible to determine the type of spikes for the time being. When Wu Da was questioned, he was wearing sneakers on his feet, and I found shoe prints with the same pattern on the soles of his shoes in the corridor outside the scene of the crime, which shows that Wu Da probably arrived at the scene wearing sneakers on his feet, not spikes, which is very convincing. ”

"Also, the door lock cylinder in the room has no traces of prying, Wu Jun has the key to the room in his hand, but the suspect climbed the window to enter the room, which is not reasonable. So I personally feel that Wu Jun should not be a murderer. ”

"Hmm." Zhang Mengqi nodded.

"Xiao Jiao, do you have any clues there? Is there any surveillance equipment around the site? ”

Xiao Jiao's head shook like a rattle: "The community is an uninhabited ghost area, there are only three houses living in Building No. 5 where the crime occurred, and two of them have not seen anyone come back all year round, and the community has almost no supporting infrastructure, let alone monitoring." ”

"That Guoxian, let's talk about it."

Lao Xian heard Zhang Mengqi call his name, and put the interrogation materials in his hand on the table: "I agree with Mengjiao's statement, according to the results of my test, Wu Jun should not be a suspect." ”

"Oh?" Zhang Mengjiao pricked up her ears.

"Although the ** in the deceased's body was left by Wu Jun, according to the test results, I can analyze that the deceased had sex with him voluntarily, and the two of them should get along very well that night."

"Can this be analyzed?" Xiao Jiao's eyes widened, staring at Lao Xian like a monster.

"Don't interrupt." Zhang Mengqi lectured.

Lao Xian habitually pushed the spectacle lenses: "According to Wu Jun's materials, he had a relationship with the deceased on the bed in the bedroom, but I extracted Wu Jun's ** sample in the toilet lid and shower area of the bathroom." This shows that the two of them should have taken a bath after having a relationship, and I detected the ingredients of shower gel on the wipe sample of the corpse, which is consistent with Wu Jun's confession. ”

"Also, I extracted a brand new pair of white women's underwear under the bed in the bedroom, on which Wu Jun's *** was detected, and then I found a stained red women's underwear in the washing machine in the bathroom, and on this underwear, I only detected the DNA of the deceased. There was only this pair of dirty underwear in the whole room, which I think the deceased should have changed out that night. ”

"Just imagine, if Wu Jun forced the deceased to have sex with him, how could the deceased take a leisurely shower and change into a pair of clean underwear after he was raped? Therefore, I judge that the deceased had a relationship with Wu Jun, and it is very likely that it was voluntary. ”

"Brother Xian, do you mean to say that Wu Jun has no motive to kill?" Zhang Mengjiao asked rhetorically.

"If according to the interrogation materials, then he really has no motive to kill."

Zhang Mengqi's fingers tapped the table with a rhythm:

"Through my observations, I also feel that Wu Jun is not lying, and his painful expression in the courtyard of the criminal police team cannot be pretended, this is one of them. Second, Wu Jun's confession basically has some on-site physical evidence to corroborate, and he doesn't know what our on-site investigation is, but his confession is consistent with some of the circumstances of our on-site investigation, which is enough to show that his words may really be true. I think that Wu Jun can rule out suspicion for the time being, do you have any other opinions? ”

"Actually, there's one more thing I forgot to mention." Zhang Mengjiao just wanted to say "no", but Lao Xian hurriedly interjected.

"Which point?"

"When we first entered the scene, did we smell a choking smell?"

"Yes, that's the case." I remembered the smell deeply, so I hurriedly replied.

"After my inspection, it was pepper. The pepper came from the deceased's house. ”

"You mean to say that the suspect turned the kitchen into such a mess just to find pepper?" Zhang Mengjiao was surprised.

"That's how it should be." The old man nodded in reply.

"Looking for pepper at the scene, this shows that the suspect does not know the situation in the deceased's home, it used to be Wu Jun's home, if he wants to find pepper, he should not make a mess of the kitchen, so his suspicion can also be ruled out from this point." Zhang Mengjiao followed Lao Xian's train of thought and came to a point.

"Yes, that's what I mean." After Lao Xian finished speaking, he clamped the appraisal report in his hand with a clip.
