Lan Jingguo found the video of the fruit selling area of the supermarket and started watching it at 9:30 when the employees started to work. This time, he didn't dare to adjust the speed too fast, and changed it to play at twice the speed.

Qin Jinjun stood on the sidelines and stared intently at the computer screen, keeping an eye on everyone who stopped in front of the container selling red apples, observing if they had any suspicious behavior, but found nothing.

Approaching 12 o'clock in the afternoon, a female employee who looked to be in her thirties came to the red apple container, she looked at the container, raised her left hand and reached into her jacket pocket and pulled out a yellow object. Lan Jingguo paused and zoomed in slightly, holding a red apple wrapped in a yellow foam net. After resuming the playback, the female employee put the apple in a more conspicuous place in the container and left. A few minutes later, the deceased appeared in front of the camera, she came to the apple container, reached out to touch it, and finally found the apple that the female employee had put down, and took it back to the office.

"She's touching the stalk of an apple." Lan Jingguo frowned and said.

"It should be, the light gray note is similar to the color of the apple stalk, and it is difficult for the deceased to tell at a glance which one is the one sent by the lover." Qin Jinjun replied.

"Is the lover the female employee?" Lan Jingguo asked with an unnatural expression.

Qin Jinjun rolled his eyes at Lan Jingguo and said sarcastically: "It can be seen how low the IQ of the murderer in the case you solved before was that he would be caught by your stupid uncle." They can keep their romance as secret as an apple to pass the book, do you think the lover will personally deliver the apple to the container? As soon as the man put the apple, the woman came out to get it, which was too obvious. Naturally, the lovers who couldn't see the light asked the female employee to help put the apples, and the deceased was the supervisor, with her power to cover the sky with one hand in the supermarket, the female employee did not dare to refuse, nor did she dare to publicize their ugly things. ”

Qin Jinjun's words made Lan Jingguo unable to refute, so he could only glare at her.

"Actually, Uncle Lan, I shouldn't say that your IQ is low, I think your IQ is fine, it's just that your EQ is too low to understand this complex interpersonal relationship." Qin Jinjun changed his words and comforted in a playful tone.

Lan Jingguo was even more speechless, and glared at her again.

"You should have forensics about the foam mesh cover wrapped in the poisoned apple, right?" Qin Jinjun asked.

Lan Jingguo nodded and added, "The colleagues of the Forensic Identification Department have detected multiple sets of fingerprints on the net cover, one of which is the deceased. ”

"We only need to collect the fingerprints of the supervisor's lover and the female employee, compare them with the fingerprints on the net cover, and if they match, we can prove that the poisoned apple eaten by the deceased was given by the lover." The corner of Qin Jinjun's right mouth was raised, revealing a smug smile, and added: "We will call the female employee over for interrogation now, and we want to ask for the information of this lover in her mouth." ”

Lan Jingguo snorted and opened a folder on his computer that was named Supermarket Employee Files. Because of this murder, the criminal police identified all the employees and bosses in the supermarket as suspects, investigated them, archived the information of everyone they found, and handed it over to Lan Jingguo and the head of the Criminal Investigation Department. Lan Jingguo opened the files of female employees one by one, and compared the appearance of female employees in his memory with the photos displayed in the files.

Qin Jinjun suddenly handed the mobile phone to Lan Jingguo, which showed the photo of the female employee in the video, which she took when she watched the video just now.

The tacit cooperation between the two made the file of the female employee quickly found, her name is Du Ting, 37 years old this year, is a divorced single mother. Lan Jingguo picked up his mobile phone, dialed Du Ting's contact number according to the file, and waited for a while before the phone was connected. Qin Jinjun motioned for Lan Jingguo to turn on the speakerphone.

"Hello, may I ask who you are?" A woman's timid voice came from the other end of the phone.

"Hello Ms. Du, you came to the Zhongguang Police Station on the night of the 9th to cooperate with a police officer surnamed Fan to record a statement, and I am his boss." Lan Jingguo made a brief self-introduction.

"Oh, hello officer, is there anything you want me to do?" Du Ting seemed relieved and asked.

"We have made a new discovery here, and we would like to ask you to come to the police station again to cooperate with the investigation." Lan Jingguo said undoubtedly.

Du Ting was silent for a while and said, "Can you go back in a few days?" I still have something to do at home. ”

"Ms. Du, please make it clear that I am not discussing with you. If you refuse to cooperate, I have reason to arrest you for obstructing the justice of justice, and you will still have to cooperate with us at that time, and it is up to you to choose to cooperate or be arrested by us. Lan Jingguo said in a deep voice.

"Don't, don't, I'll go now." Ms. Du was frightened enough by Lan Jingguo's words, and immediately agreed.

After hanging up the phone, Qin Jinjun on the side couldn't help laughing, she patted Lan Jingguo's shoulder and said, "Uncle Lan, you are quite good at bluffing." ”

"I've seen a lot of this kind of person, and they will never cooperate if they don't scare them." Lan Jingguo shrugged.

At 11:02, the landline on Lan Jingguo's desk rang, and he picked up the phone.

"Boss, there is a lady surnamed Du who is downstairs in the police station now, and she told the police officer in charge of reception on the first floor that she was looking for you." Outside, Xiao Fan said.

"Well, please go downstairs and bring her up, and send her directly to Interrogation Room 1, where I'll wait for you." Lan Jingguo hung up the phone after speaking.

Nearly ten minutes later, Xiao Fan took Du Ting to the first interrogation room. As soon as she opened the door, she saw that only Qin Jinjun was sitting in the seat of the interrogation suspect, with a Bluetooth headset in her left ear, and Lan Jingguo was already on the other side of the interrogation room ready to watch the interrogation.

"Ms. Du Ting, please take a seat." Qin Jinjun raised the right corner of her mouth and said to Du Ting, and then turned to Xiao Fan beside her and said, "Officer Fan, please go out first, I'll be in charge here." ”

Xiao Fan glanced at the big mirror behind Qin Jinjun, turned his head and walked out of the interrogation room, and closed the door by the way.

Du Ting looked around the interrogation room with some panic, and when her eyes fell on Qin Jinjun, her eyes changed from panic to doubt, she slowly walked over, sat on the chair opposite Qin Jinjun, and asked timidly, "May I ask if you will record a confession for me today?" ”

"That's right." Qin Jinjun nodded, and said with a playful expression on his face: "Are you thinking about why this policewoman is so young?" ”

Du Ting smiled awkwardly.

"Relax, I just want to ask you some regular questions, and I can let you go when I'm done." Qin Jinjun pretended to fiddle with the blank A4 paper in front of her.

Du Ting hummed, put her hands on the table, and looked at the table with her head slightly down.

"May I ask who is your supervisor's lover?" Qin Jinjun asked sharply, making Du Ting on the opposite side tremble with fright, and almost fell off the chair.

"If you don't know interrogation, don't do the work!" Lan Jingguo, who was standing behind the one-way perspective glass, was choked by Qin Jinjun's anger.

"What kind of question are you asking? I don't know the supervisor well, how do I know she has a lover? Du Ting buried her head lower, and her voice trembled slightly.

"Slowly induce her to tell the truth, be patient." The Bluetooth headset came with Lan Jingguo's prompt.

Qin Jinjun didn't speak again, turned over the A4 paper on the table, it turned out that the bottom side was printed with a full page of words, and there was a ID photo in the upper left corner of the paper, it was a twelve or thirteen-year-old boy, and his appearance was somewhat similar to Du Ting.

"Your son is good-looking, but it's a pity that he is a sick man. If you go to jail for giving a false confession, who will take care of him? Let your mother come? That's not good, she's almost seventy, how can she have so much energy to take care of your frail and sickly son. Qin Jinjun said in a regretful tone, this information was just asked by Chen Xiao to check, and it was part of Du Ting's son's medical records.

"You ......" Du Ting looked up at Qin Jinjun suddenly, her eyes were full of horror, and she pleaded in a crying voice: "Please don't do this, I say I, as long as I know everything I know." ”

"Miss Qin, it's a violation of the law for you to do this...... In the headphones, before Lan Jingguo's words were finished, Qin Jinjun took off the Bluetooth headset and put it on the table.

"At the end of February this year, the supervisor got along with her newly hired young guy in the supermarket." Du Ting answered the first question Qin Jinjun asked.

"What's this guy's name?" Qin Jinjun asked.

"Lin Xiaomiao." Du Ting replied.

Qin Jinjun handed Du Ting a pen and handed her the paper with her son's medical records printed on it, asking her to write her lover's name in the blank space on the paper. She looked at the photo of her son on the paper with an unnatural expression, and wrote the words "Lin Xiaomiao" with a trembling hand.

Qin Jinjun took the paper back in front of him, looked down at the words written by Du Ting, then raised his head, his eyes fell on Du Ting's face again, and asked, "Why did they let you put apples?" ”

This was their idea, the supervisor didn't want her husband to find out about her and Lin Xiaomiao's ugly affair, so she thought of a way: she asked Lin Xiaomiao to write what she wanted to say to her on a note, and then wrapped the note around the stalk of the apple, fixed it with transparent glue, Lin Xiaomiao would hand over the apple to me before going to work every day, and I would put the apple on the shelf where the apple was sold when I was about to have lunch, and the supervisor would take the apple away after twelve o'clock. When I was about to get off work, the supervisor would come to me in person, hand me another apple, and ask me to pass it on to Lin Xiaomiao. Du Ting described the whole process of Apple's book in detail.

"So was there anything unusual between the deceased and his lover a few days before the crime? For example, quarrels and the like. Qin Jinjun asked.

"They basically don't see each other except on weekends, but Lin Xiaomiao seems to be a little abnormal the day before the crime. That day, he handed me the apple as usual before going to work in the morning, but his expression was sullen at the time, and he wanted to ask him what was wrong, but he didn't want to get into trouble, so he didn't ask. But on the morning of the crime, when he gave me the apples, he returned to his usual happy appearance, I thought their conflict had been resolved, but I didn't wait for the supervisor to deliver the apples after work that day. Then I heard that the director had died, and it scared the hell out of me. When she said this, Du Ting's face turned a little pale, and she still seemed to be still apprehensive about the news that the director had died.

"Why didn't you say these things when you recorded your confession that day?" Qin Jinjun asked.

"I didn't say it because I thought it didn't have much to do with it." Du Ting's face turned paler.

"Is the apple Lin Xiaomiao gave you different from usual on the day of the crime?" Qin Jinjun asked.

"No, no, it's just a normal apple." When she said this, Du Ting's eyes dodged, and although the movements were fleeting, they were still captured by Qin Jinjun.
