"Advisor Chen! Early! "Before nine o'clock in the morning, Chen Yiyan had already arrived at the police station of the first district.

"You're early." After Chen Yiyan said hello, he went straight to the evidence room.

"Is Old Jiang here?" Chen Yiyan knocked on the door and asked.

"Consultant Chen? I'm here, you wait a minute. After a while, the door to the evidence room opened.

"What you asked me to test yesterday is out, and here are the results." Jiang Sheng handed the list to Chen Yiyan.

Chen Yiyan took the list, glanced at it and said, "Thank you, Officer Jiang." ”

"It's okay, it's all your own."

Saying goodbye to Jiang Sheng, Chen Yiyan came to Ji Ping's office.

"What happened to Dong Hua?" Chen Yiyan opened the door directly and asked.

"I notified Li Qinlan last night, and he said that he would not pursue it, so I will let the person go." Ji Ping put down the documents in his hand and looked at Chen Yiyan.

Chen Yiyan smashed it, smashed it, and nodded. Ji Ping was still looking at him: "Aren't you able to solve the case today?" ”

"Yes. But you have to go with me to the victim's house first. Chen Yiyan made a gesture of please.

Ji Ping looked at Chen Yiyan with slightly slanted eyes, and then got up: "Okay, I'll see how you solve the case." ”

"Call Xiao Zhao and them too."

"Okay."

At nearly ten o'clock, several people came to the villa community.

Chen Yiyan motioned for Ji Ping to stop at the doorman, and then Chen Yiyan poked his head out to look at the security guard who stopped him yesterday and said, "Things, have you taken them?" ”

"Take it." The security guard was about to get up.

"You give it to the police car in the back. Thank you for your cooperation. ”

"Yes, officer."

"Well, then we're in."

"Okay, officer."

Ji Ping looked at Chen Yiyan strangely: "What's the situation, what did you ask the security guard to take?" ”

Chen Yiyan smiled: "Evidence." ”

"Evidence? What evidence? ”

Chen Yiyan turned his head to look at Ji Ping: "You'll know in a while." Ji Ping is accustomed to Chen Yiyan's conversations.

The police car stopped outside the victim's villa. Chen Yiyan and Ji Ping got out of the car, and Li Qinlan had already opened the door and waited.

"I'm bothering you again." Chen Yiyan and Li Qinlan greeted each other.

"It's okay, have you done your investigation?" Li Qinlan gave up the seats and let the two of them into the house.

"The person who posted the threat letter told you about it yesterday. You're not going to pursue it, and then you're here today to investigate the murderer. Ji Ping sat down on the sofa at Li Qinlan's signal.

"Are you here to find out what evidence is there at the scene?" I don't know if the word evidence is a coincidence or what, Li Qinlan and Chen Yiyan both mentioned it, and Ji Ping glanced at Chen Yiyan.

Chen Yiyan understood that Ji Ping asked him to speak, so Chen Yiyan spoke: "No, we already have the evidence." I'm here just to ask you. ”

"Didn't you ask yesterday? What else do you want to ask today? Li Qinlan was a little puzzled.

"You're calm." Chen Yiyan said to himself: "You should have been holding back for a long time." ”

"I've been holding back for a long time." Li Qinlan's tone changed.

"To your husband, you should have found out." Chen Yiyan walked across from Li Qinlan.

"Found what?" Li Qinlan looked at Chen Yiyan's eyes.

"Discovery." Chen Yiyan paused and continued: "I found out that your husband was cheating. ”

Chen Yiyan clearly saw that Li Qinlan's pupils dilated in an instant, which was a manifestation of an adrenaline surge.

"My husband didn't cheat." Li Qinlan turned her head and said.

"I found out about your husband and Li Lan."

Not only did Li Qinlan suddenly look at Chen Yiyan, but even Ji Ping looked at him.

"You should know that Li Lan is a student of your husband's elective class."

Li Qinlan didn't reply, and Chen Yiyan continued: "Your husband recommended Li Lan to intern at Lisheng Company, and something that shouldn't have happened to them during this period. ”

"I don't know." Li Qinlan was obviously a little angry.

"Not only do you know about it, you've also seen the threatening letters."

"Do you know about threatening letters? Didn't you say you hadn't seen it. Ji Ping looked at Li Qinlan.

"I haven't seen it." Li Qinlan refused.

"I've had your fingerprints checked and match the ones on the letter. That is, you have taken the threat letter and read it. ”

Li Qinlan wanted to refute, but Chen Yiyan spoke first: "As for your fingerprints, they were collected from the water cup you gave me when I went to the kitchen yesterday. This is a comparison list with five fingerprints on your right hand, which match the fingerprints on the letter. ”

Ji Ping took the list in Chen Yiyan's hand and looked at it: "It's true, then why are you lying?" ”

"I forgot I saw it." Li Qinlan admitted.

"You may have forgotten that you had read the threatening letter, but you couldn't forget that your husband was cheating." Chen Yiyan walked back and forth slowly: "You should have found out that your husband has an abnormal relationship with a girl named Li Lan, I guess I heard it on the phone." ”

Li Qinlan did not reply.

"You shouldn't have told your husband about this, you're a strong woman. So you keep this thing in your stomach and don't think about it. Until a few days ago, you saw a report on the news about a female college student named Li Lan who was pregnant and committed suicide by jumping off a building. That's the trigger for you to take action on your husband. ”

"You killed Zhang Sen?" Ji Ping looked at Li Qinlan and asked.

"What do you know? We've been married for more than a decade and he's never had any romantic moves. I also told myself that he was honest and loyal. But a few months ago I heard him secretly on the phone, and at first I thought he was talking about me, but I heard what he said clearly. He was talking about Li Lan, not Li Qinlan! I later found someone to check, and this Li Lan was his student. I didn't think much of it, but the number of calls I made more and more times, and every time I heard the word Li Lan. I asked him in person, and he said it was a matter of work. I also went to school to wait for him to get off work and saw him drive away with the girl! Hmph, we have been married for more than ten years and have no children. Li Qinlan looked at the two: "I know that my husband is cheating, what's the matter?" Just because I know that my husband is cheating proves that I killed my husband? Do you have proof? ”

"You're also your husband's student, aren't you?" Chen Yiyan spoke.

"Yes, I'm also his student, so I saw that he was having an abnormal relationship with another female student. I'm not surprised at all! The last sentence Li Qinlan almost shouted.

Chen Yiyan walked next to Ji Ping and whispered: "You send a message to Xiao Zhao and them to come in, the kind that wants to rush in, you must have something in your hand that the security guard just gave you." ”

Ji Ping believed Chen Yiyan and also sent a message.

The villa was quiet for ten seconds, and then I heard the door open and hurried footsteps. Chen Yiyan came in later than Ji, and he just closed the door and didn't close it.

Xiao Zhao ran to Ji Ping with two police officers, still holding something given by the security guard, which was a black garbage bag.

Li Qinlan looked at the garbage bag with wide eyes, and Chen Yiyan spoke up: "That's right, this is the garbage bag you threw away in the morning." If I'm not mistaken, the evidence is here. ”

Li Qinlan didn't speak, he watched Chen Yiyan take out a rag from the garbage bag, and there were still blood stains on it.

"This rag is the one you use to erase your fingerprints from the trophy." Chen Yiyan looked at Li Qinlan.

"Take it away." Ji Ping spoke.

The police officer stepped forward to grab Li Qinlan, Li Qinlan did not resist, and when she passed by Chen Yiyan's side, she said: "I killed the person, but God has eyes and let that woman miscarry." ”

"You'll call the detective in the future." Seeing that the case was solved, Ji Ping also breathed a sigh of relief: "How did you find out that it was Li Qinlan who killed Zhang Sen?" ”

"Didn't you see the wound of the deceased before, it was in the lower part of the back of the head? I have seen Dong Hua's height, he is half a head taller than the deceased, if he picks up the trophy and attacks the deceased, the wound should be above the back of the head. So I guess that the murderer should be shorter than the deceased, and Li Qinlan's height is very consistent. ”

"What else?" Ji Ping asked.

"I came to test it yesterday and when I asked about her husband, she was a bit of a perverse acter. It can be said that she is a little calm, but when I said that I found the person who wrote the threatening letter, she was a little surprised, or panicked, because she knew that it was not the person who wrote the threatening letter who killed Zhang Sen. As for the garbage bag, I think she knew the police were going to search the house, so she probably hid this rag somewhere we couldn't find it, I guess somewhere in this room. Yesterday I told her that when I found Dong Hua, she should be alert, when you called and said that Dong Hua was not the murderer. She should have started to rush to deal with this rag. As for why she didn't throw it away the other day, it was because she didn't feel safe enough. So I asked the security guard to put away her garbage bag this morning, saying that it was important evidence for our police. ”

"I see. So when did you start to suspect her? ”

"When I saw that picture." Chen Yiyan pointed to a photo in the cabinet.

The photo was Li Qinlan's graduation photo, and her husband Zhang Sen was sitting in the teacher's seat in the front row.

Ji Ping nodded: "Then let's go back to the police station." ”

"Hmm."

In the interrogation room of the police station in District 1, Li Qinlan is being interrogated.

"What time do you move?"

"At half past ten in the morning, I did it."

"The murder weapon used is a trophy in the cabinet?"

"Hmm."

In the observation room, Ji Ping asked Chen Yiyan: "How do you know the relationship between Zhang Sen and Li Lan." And didn't you tell Dong Hua yesterday that it wasn't Zhang Sen? ”

"If you really want to be sure, this will have to wait until Li Lan's dead fetus in her womb and Zhang Sen's paternity test. But I believe it's not Zhang Sen. ”

"Oh? Why, you don't know this person? ”

Chen Yiyan shook his head: "I really don't know this person, but the bank card tells me it's not him." I called Zhang Jiajie in the morning to ask him, and he said that he found out that there was a remittance of tens of thousands of yuan in Li Lan's previous bank card in the morning, so I asked someone to check it on the way in the morning. The money was sent from a man named Zhao Lisheng. ”

"So which one of these Zhao Lisheng is related to Li Lan? Do you want to talk to her? Ji Ping pointed to Li Qinlan in the interrogation room.

Chen Yiyan shook his head again: "It's better not to tell her, if you let her know that her husband is just helping his friend deal with Li Lan's affairs." She would think that if she killed her honest husband because she was suspicious of her husband, I don't know what she would do. ”
