Entering Liu Dandan's room again, Feng Yuan's eyes were completely different from the last time, this time, Feng Yuan's eyes swept directly over all the objects in Liu Dandan's room that could be used as murder weapons.

Glasses, figures, pen holders......

Feng Yuan turned off the light in the bedroom, and then walked to the window and closed the heavy curtain, and the light source in the room was suddenly cut off, and it was abnormally dim.

"Guo Yi!"

"Yes."

Guo Yi took the luminol reagent, starting from the place where Liu Yan fell in the corner of the wall, and then expanded outward little by little, and the spray of the reagent slowly fell in all corners of the room.

Blood stains can be washed and the room can be rearranged, but luminol reagents can make this room appear in its most primitive and sinful state.

From the corner of the wall, the fluorescent color has been moving along the floor towards the desk, but according to the test, the blood stains are drop-by-drop, and blood-colored footprints that fall on the ground.

"Captain, this ......" Lu Zhong frowned as he looked at the fluorescent color that gradually appeared on the ground.

Feng Yuandao: "I saw it, take your time, I want to see what Du Xuelin used as a murder weapon." ”

"Hmm."

Guo Yi frowned and sprayed the reagent on every part of Liu Dandan's desk, not even the handle of the drawer, he was very careful, he wanted to see where the blood would extend in the end.

Suddenly, all three people in the room breathed a sigh of relief.

Lu Zhong said: "Captain, you didn't guess wrong, that Du Xuelin really dragged a murder weapon casually, but he didn't even have the courage to destroy the evidence afterwards." ”

Feng Yuan stared at the stainless-steel pen holder dyed pink on the desk and muttered: "I think, he should be worried that Liu Dandan will suddenly come back and find that the room is missing the pen holder and revealing the filling, after all, compared to this, no one will suspect that Liu Yan's death is not an accident." ”

Lu Zhong smiled and said, "But you still found out." ”

"Well, it's just luck." Feng Yuandao: "Guo Yi, the time for fluorescence to appear is limited, hurry up and take pictures for evidence." ”

“…… Be. ”

Guo Yi took out his mobile phone to take pictures step by step, but fortunately, the camera that came with the mobile phone has a high pixel and it does not affect it.

Feng Yuan frowned and said, "It's really careless, you should bring a camera, and you have brought all the luminol reagents." ”

"Captain, there are only two cameras in the bureau, one is in the forensic doctor's place, and the other is in the technical investigation, we didn't bring the technical investigation to the scene this time, where did the camera come from!" Lu Zhong complained quietly.

"Tsk! I'm going to complain to Lao Ye another day, comrades have worked hard to investigate the case, and this hardware can't keep up! ”

Lu Zhong dismantled the stage and said: "It's useless for you to complain to the director, these are all administrative and financial responsibilities, every expense has to be reported, and, in fact, the two cameras can also be turned over, I think Guo Yi is very good with the additive, and the camera is also heavy on the back." ”

"Hey! Your captain, I want to keep your equipment updated to keep up with the times, but you're not happy anymore! ”

Lu Zhong laughed twice and said: "Captain, really, now the mobile phone is quite up to date with the times, and it also saves costs for the bureau, I think it's good." ”

“……”

"Captain, it's alright." Guo Yi stepped forward at the right time and interrupted the awkward atmosphere.

"Alright!" Feng Yuan touched his nose and said, "Then pack the evidence."

, we close the team. ”

"Yes."

……

In the interrogation room of the Municipal Bureau, Du Xuelin opened his eyes and looked at the environment in the interrogation room nervously, people! When I entered the palace, I was always curious and scared, and it would be good to come a few more times, this is what Feng Yuan always thought.

"Du Xuelin, let's talk about it! What happened after Liu Dandan left that day? Feng Yuan looked at Du Xuelin, who was cowering, and said.

"Officer, I told you a long time ago, I don't know what else you want to know, anyway, after Dandan left, I waited for the ambulance to arrive." Du Xuelin gritted his teeth and refused to admit it.

"Then tell me, what is the blood stain on the stainless steel pen holder in Liu Dandan's room?" Feng Yuan picked up the printed photo and looked it in front of Du Xuelin's eyes.

Du Xuelin's eyes instantly showed a hint of panic, and he said: "I don't know, officer, I really don't know, maybe, when the child is in the room by himself, he may accidentally scratch something, and it may not be stained with blood." ”

"Got blood?" Feng Yuan suddenly smiled and said, "Then these bloody footprints are also because where Liu Dandan scratched and got blood?" ”

Seeing that Du Xuelin was speechless, Feng Yuan continued: "Look at your weak heart, you want to lie to us again, the autopsy results have come out, the back of Liu Yan's head has indeed been hit twice, and we have brought back the murder weapon, there are no fingerprints on it, do you know what it means?" The things in Liu Dandan's room, and they are commonly used things, there are no fingerprints on it, but why don't you even have Liu Dandan's fingerprints? ”

"I ...... I do not know. ”

Yes, Feng Yuan can see it clearly, no matter what they say today, Du Xuelin will definitely want to settle the matter with a sentence of not knowing.

"Du Xuelin, you said you don't know anything, so do you know when Liu Yan cheated? Who is the object of cheating? Feng Yuan threw a bombshell again.

Du Xuelin's face was stunned for a moment, and then he was stunned: "I, I don't know, although Yan Yan has someone else, our relationship is still there......"

Feng Yuan rolled his eyes helplessly.

Lu Zhong on the side raised his eyebrows and said: "Our people found out that you married Liu Yan back then, and you were alone in the Liu family, at that time you were just a normal student who had just graduated from the countryside, you had no relationship, no resources, and your ability was not very good, you have been a substitute teacher in the primary school, until you climbed to the Liu family and Liu Yan got married, you were transferred to the current school, and you got the respect you have never received, but it's a pity that ......"

Looking at Du Xuelin's increasingly pale face, as well as clenching his fists, Lu Zhong did not have any sympathy, he continued: "It's a pity that you signed an agreement before marriage, and the Liu family's property has nothing to do with you, what makes you even more depressed is that you found out that Liu Yan actually couldn't have children after you got married, you found out that you were deceived, you were very angry, but you have enjoyed the dignity, rights and money she brought you, so you can't give up, you can only take this childless marriage, and later, you went to the orphanage to adopt a daughter." , Daughter who has nothing to do with you, Du Xuelin, you actually hate Liu Yan very much in your heart, Liu Yan's parents have passed away, and the child is not biological, as long as Liu Yan is dead, all the property in her hands will be yours, right? ”

Feng Yuan listened to Lu Zhong's words with interest, but he didn't expect that the child who was easy to be shy and dumb at the beginning had grown to such a point now, which was good!

Du Xuelin's fists clenched, his

The lips trembled so much that I couldn't tell whether I was excited or scared, but my mood was very unstable. Feng Yuan was very curious, how could this person with such poor psychological quality suddenly think of killing Liu Yan that day and be in trouble forever?

Du Xuelin looked at the two people in front of him, he didn't expect them to investigate so meticulously, it was as if he had stripped himself naked for others to see, and all the darkness and despicability in his heart were exposed under the blue sky and white sun, as if Ling Chi.

Thinking like this, Du Xuelin suddenly collapsed, he wanted to cover his face, but his hands were restricted, and he could only let the tears slip from his eyes, and then the fog in front of him was misty, and he couldn't see anything clearly through his glasses.

"I don't want to either, it's all forced by their Liu family." Du Xuelin simply gave up on himself and said: "When I was young, I really wanted to use the Liu family to realize my wishes, but I put up Liu Yan, we were also true love at the beginning, I just didn't think that she couldn't have children, is it wrong for me to want a child of my own?" She can't give birth, but she doesn't allow me to find a surrogate, she doesn't want me to have my own child, so she mentioned to adopt a child, I thought, adopt it, and then have your own child in a few years, but this time it's been more than ten years, Liu Yan said, as long as I dare to surrogate outside, let me go out of the house, okay, I can bear it, but what about her, she has a few stinky money, and she actually engages in men outside, and brings people to the house, isn't this just using me as a tool for marriage? Now I'm useless, kick away without mercy......"

Saying that, Du Xuelin seemed to think of the difficulties of these years, and tears flowed down, and he said as he flowed: "Officer, can you help me take my eyes off, this is strange and uncomfortable." ”

“……”

Feng Yuan was speechless and gave Lu Zhong a look, and the latter pursed his lips and smiled and stepped forward to take off his eyes.

Feng Yuan said: "Since you said so, then Liu Yan hit the back of the head with you?" ”

Du Xuelin pursed his lips and thought for a while before he nodded, obviously he didn't want to bother to argue anymore, he said: "That day, after Dandan left, Liu Yan sat on the ground, very weak, I had already called an ambulance, but somehow, I suddenly thought of this stubble in my mind, the ghost made the god worse, I didn't think about it again, I just felt that if I didn't do it this time, I wouldn't have a chance in the future, so ...... I casually dragged something down from Dandan's table, and without looking at it at the time, I smashed it against Liu Yan's wound again. ”

Feng Yuan continued: "What did you do after that? ”

Du Xuelin sniffed and thought for a while: "After that, I was very scared, before the ambulance came, I cleaned the blood stains on the ground and the pen holder, in fact, I was very nervous at the time, and I was not sure whether Liu Yan was dead, the nurse carried her into the ambulance like that, and it was also when the car was in the car that Liu Yan died." ”

"Officer!" Du Xuelin suddenly grabbed the edge of the table in front of him and said, "I'm not a murder!" She didn't die at the time, she died in the ambulance. ”

"Now that you have pleaded guilty, wait for the result in the detention center! Whether it is murder or not, after going to court, the judge will have a verdict. Feng Yuan said coldly.

"What about Liu Dandan? If this is murder, she is also one of the murderers, and you are going to let her go like this? Du Xuelin said without giving up.

"Liu Dandan, we will find it, this is not something you should worry about."

After speaking, Feng Yuan and Lu Zhong left the interrogation room, leaving Du Xuelin, who regretted alone, in pain in the small room.
