Qin Jinjun drove to the Zhongdong District General Police Station, and when he arrived downstairs, Lan Jingguo was already standing in front of the elevator waiting. The two greeted each other, then walked into the elevator and went up the seventeenth floor.

Lan Jingguo took Qin Jinjun to the No. 3 interrogation room, and the two walked into the observation room behind the one-way perspective glass, through the glass she saw the big one sitting in the interrogation room facing them, and the person in charge of interrogation was the police officer Xiao Fan. Lan Jingguo took out his mobile phone, the screen showed that he was talking, he canceled the waiting button and said to Xiao Fan in the interrogation room, "Let's start." ”

"Ms. Tianyuan, please take off your hat, sunglasses, and mask." Xiao Fan said.

"She's a woman?" Qin Jinjun lowered his voice and complained.

Lan Jingguo ignored her and watched the interrogation process carefully.

At first, Tian Yuan refused to take it off, and it really took Xiao Fan a lot of lips and tongues to give in. The moment she revealed her true face, what appeared in the eyes of everyone was an ugly face covered with scars. As a professional police officer, Xiao Fan did not stare at her face, but continued to interrogate: "May I ask what is your relationship with the two deceased?" ”

"It's okay." Tian Yuan replied in a hoarse voice.

"And what was your motive for killing them?" Xiao Fan asked.

"They killed my best friend." Tian Yuan said hatefully.

"Please tell me more about what happened." Xiao Fan said.

"My face was ruined in a car accident a few years ago, my mother died in a car accident, and since then I have been living in the shadows until I was treated by a psychiatrist, my condition is much better, she suggested that I go to volunteer, and I went, and it has been more than two years now. Five months ago, I met Guan Xiaolin, a kind-hearted seven-year-old girl at the Ping An Street Integrated Service Centre, who joined the service centre volunteer group in early April. In the volunteer group, the younger generation of volunteers thought I was strange, not only because of my dress, but also because of my quiet demeanor, although they didn't say anything, I knew in my heart that they were always avoiding me, intentionally or unintentionally. Only this little girl is different from them, she will take the initiative to come and talk to me, and the first thing she said to me is: the weather is very hot, and wearing long sleeves is easy to get prickly heat. After spending a long time together, I found out that she was a very kind child, and we gradually became good friends. At this, Tian Yuan lowered his head and raised his hand to wipe away his tears.

Xiao Fan pushed the disposable water cup filled with warm water in front of Tian Yuan, she understood, picked it up and took a sip, sighed and continued her story: "Xiaolin suffers from moderate depression, this is what the volunteer group manager told me. Xiaolin volunteered at the service center under the guidance of a psychiatrist like me, and I felt sympathy for her because I was also suffering from depression. The cause of her illness is the supermarket fraud gang reported in the news not long ago, Xiaolin is the first victim of the fraud case, since she was wrongfully accused of stealing her wallet, her father beat and scolded her all day long, and it didn't take long for her to suffer from depression. On September 6, the news reported the facts, and Xiaolin had a psychological breakdown and committed suicide that night. And from that day on, I vowed to kill everyone who had framed Xiaolin. ”

After Tian Yuan fell silent, Xiao Fan opened his mouth and continued to ask: "May I ask how you killed the first deceased, Shi Ailian?" ”

"The fraud case was tried on the morning of the 7th, and I went to hear it. Unexpectedly, the judge actually acquitted Shi Ailian's slut and released her in court, I was furious all of a sudden, put on the volunteer vest of the service center and followed Shi Ailian all the way to the supermarket, which took a whole day. However, I found out a lot of things, the slut and a male employee and a female employee were passing apples to each other, this series of actions made me very confused, so on the morning of the 8th, I hid outside the window of the employee rest room and peeked, and saw the male employee give the female employee an apple, and the female employee put it in the bag. When they were all out to work, I sneaked into the staff lounge and stole the apples from the female employees' bags, took them home and examined them closely, and found a note wrapped around the apple stalk. I took out the note and spread it out to read it carefully, the content was about the breakup, so I instantly figured out that the male employee and Shi Ailian had a leg, and the female employee was equivalent to a carrier pigeon, so I came up with a plan to kill the slut. Tian Yuan paused, picked up the water cup and took another sip of water.

"I used 150 grams of bitter almonds to extract sodium cyanide*, waxed the skin of an apple, and then applied the highly toxic sodium cyanide to the waxed skin, and the poisoned apple was made. I wrote a gray note to the slut in English: Death is coming after you. To mislead the police into thinking that the murderer is the slut's lover. Wrap the poisoned apple in paper, put on a foam mesh cover to prevent the poison from getting on your hands, fix the note on the apple stem, and the murder weapon is completed. I took the poisoned apple and waited for the female employee to get off work at the door of the supermarket, and then followed her all the way, waiting for the opportunity to catch her and coerce her to send the poisoned apple to the slut, she agreed, and the whole plan was completed. Tian Yuan took another sip of water after speaking.

"May I ask how you killed the second deceased, Zhu Yi?" Xiao Fan didn't let her stop for long before asking.

Tian Yuan let out a smug laugh and said, "This one is much simpler. I knew that this slut Nine would be released that day, so I waited outside the detention center for a long time. As soon as she came out, I followed her all the way to the bottom of her house, and I found that the building where she lived was one of the areas that our volunteer group was responsible for cleaning. I hurried back to the service center and asked the administrator to replace the volunteer who was responsible for cleaning the building that week with me, and I stayed in the building for several days, arriving at 8 in the morning and leaving at 7 in the evening, to find out the time of the slut's comings and goings. It wasn't until the thirteenth day, when the slut went upstairs, that she smiled at me with a disgusting and hypocritical smile as usual, and I couldn't hold back any longer, and when she passed by me, I pushed her downstairs with all my might. After making sure she was dying, I immediately ran back to the service center. ”

"Why did you suddenly surrender today?" Xiao Fan asked.

"Because the high school student and female detective on the news went to the service center to find me today, I knew that the matter must have been exposed, and in order to reduce the sentence, I could only voluntarily come to the police station to surrender." Tian Yuan said helplessly.

After looking through the glass in one direction, Lan Jingguo looked at Qin Jinjun and frowned and asked, "How do you know that she is there?" Why didn't you call me to come with you? ”

Qin Jinjun interrupted in a stern tone: "She's lying!" She walked out of the observation room quickly, then walked into the interrogation room, kicked Xiao Fan out, and let her continue the interrogation.

"Xiao Fan, you come to the observation room first, and leave the rest of the work to her." Lan Jingguo said to Xiao Fan on the other end of the phone.

Qin Jinjun sat opposite the countryside, with a faint smile on his face, and asked, "Is it fun to apply lubricant to my car?" ”

Tian Yuan shrugged and did not answer.

"How do you know that the street lights near Ya'an Garden are turned on at seven o'clock in the evening?" Qin Jinjun asked.

"I just know." Pastoral shrugged indifferently.

"In the first murder case, the female employee you said in your mouth, her confession was that someone suddenly covered her mouth from the side, but your statement was to follow all the way, waiting for an opportunity to catch her, this is different from the confession of the witness, how do you explain it?" Qin Jinjun stared at her face, observing any slight changes in her expression.

"I don't remember the details very well, maybe as she said, I came out of the crowd and covered her mouth." Tian Yuan replied calmly.

"Bang!" Qin Jinjun got up and slapped the table with both hands, her emotions seemed very excited, and she shouted: "You are lying, you didn't do the first murder, you are shielding another murderer!" ”

"Whatever you say, I've recruited everything that should be recruited, what can you do with me?" Tian Yuan still looked at her calmly, and he had no fear of Qin Jinjun, who was in a state of rage.

Lan Jingguo opened the door and came in and dragged Qin Jinjun back to his office.

"She's already pleaded guilty, you don't hold on to these little details, maybe things aren't as complicated as you think." Lan Jingguo said.

"Small details? Definitely not! Qin Jinjun said emotionally: "There is a big discrepancy between what she said and the confession of the witness, and the first murder case was definitely not done in the pastorary." The most important thing is that the countryside can't just rely on tracking, it only takes half a day plus an apple with a note to find out what happened between the dead and the lover so clearly, if it were you or me, do you think you can do it? My answer is no. ”

"If you insist that there is another murderer, I want you to show substantial evidence, and stop using your inferences to prevaricate me." Lan Jingguo's mood also became excited.

"Okay, I'll look for it now, and we'll see." Qin Jinjun turned around and prepared to leave.

"Stop." Lan Jingguo ordered: "Hand back that evidence, I hope you don't do stupid things behind my back in the future." ”

Qin Jinjun turned to Lan Jingguo and yelled, "No, the diary is still useful to me!" ”

"Give you two days, and if you can't find evidence and another murderer, I'll close the case!" Lan Jingguo also roared.

......

When Amelia returned home, there was a deafening sound in the living room, she changed her shoes from the entrance and walked into the back room, and saw Qin Jinjun holding a game controller with a puffed face, using the TV to connect to the newly bought game console and play the game of killing zombies. She frowned suspiciously, and turned her head to look at the table in front of the kitchen, on which was the takeaway that Qin Jinjun bought for her.

Walking over slowly, Amelia sat down next to Qin Jinjun, put her hand lightly on her shoulder, and asked softly, "Rough day?" ）”

“I'm killing zombies. Do you want to play together. Qin Jinjun replied unanswered.

Amelia snatched the gamepad, Qin Jinjun's game character was quickly besieged by zombies, and was bitten to death in less than ten seconds, and then the words "Game over" popped up on the screen, and she complained: "Hey! (Hey!) You killed me. ）”

"I am having a bad day too,my girlfriend didn't cook dinner for me. Amelia feigned seriousness.

"I am not your girlfriend yet,silly Amy.Go eat your dinner,take a hot bath,then play game with me,okay? Go eat your dinner, take a hot shower, and play games with me, okay? Qin Jinjun took the gamepad back and gently kissed Amelia on the face.

Okay. Amelia got up and went to the table to eat.

Because of Amelia's movements, the off-white baseball jacket on the sofa slipped to the ground, and a corner of the photo was revealed in the pocket of the jacket, Qin Jinjun frowned slightly, put the gamepad aside, and leaned down to take out the photo.
