According to Meng Yu and Xiao Qin's investigation, on the afternoon of June 6, Yan Yiyi's last place of appearance was a small bookstore called "Xuehai Wuyan", and the owner of this bookstore, Wu Zhenguo, was Yan Yiyi's best friend, Wu Xueyao's father.

According to Wu Xueyao's recollection, after school on June 6, she and Yiyi first went to a dessert shop near the school to eat, and then went to her father's bookstore to read novels together. At around 5 o'clock, Wu Xueyao's mother suddenly called and asked her to go home to help take care of her sick grandmother, and she had something to go out. At that time, Yan Yiyi still wanted to stay in the bookstore for a while and finish the story, so the two girls said goodbye. That was the last time Wu Xueyao saw Yan Yiyi.

Wu Zhenguo, the owner of the bookstore, gave the following explanation: After Wu Xueyao returned home, Yan Yiyi continued to read books in the bookstore for half an hour, and left the bookstore at about 5:50, and he didn't know where he went after that.

Meng Yu and Xiao Qin searched for potential witnesses along the streets near the bookstore and contacted the relevant authorities to retrieve surveillance footage in an attempt to figure out Yan Yiyi's whereabouts next.

The results were disappointing, not only did they not find any witnesses, but they also did not find Yan Yiyi in the surveillance. This shows that Yan Yiyi was probably taken away when she first walked out of the bookstore, and then transferred the hostages in some way. If not, it is the bookstore owner Wu Zhenguo who has lied.

A few hours later, Gu Song slapped a search warrant on the cash register and said coldly to Wu Zhenguo: "Boss Wu, we suspect that you are related to a child abduction case that occurred on June 6, and now we will search your bookstore and your upstairs residence in accordance with the law, please cooperate with our work." ”

Hearing this, Wu Zhenguo's face turned blue in an instant. He stared at the search warrant in front of him with wide eyes, and asked in surprise, "Why do you suspect that I kidnapped my daughter's classmate?" Just because she came to my bookstore on the day she disappeared? ”

"Nope." Gu Song immediately corrected, "To be precise, it should have disappeared after coming to your bookstore." ”

"What do you mean?" Wu Zhenguo felt that he had been greatly insulted, and he was so anxious that he almost jumped up. "You suspect I hid her? Why should I do this? ”

"Boss Wu, your bookstore is operating at a loss, right?" Gu Song said and looked around the store for a week, and finally landed his eyes on a small wooden door marked "Idlers are not allowed to enter", and glanced at Meng Yu and Xiao Qin. The two men nodded knowingly, put on their gloves and walked towards the small door. Wu Zhenguo was about to step forward to stop him, but Gu Song grabbed his arm and said, "Boss Wu, what are you nervous about?" Could it be that there is something unsightly hidden in it? ”

"It's the utility room, it's ...... inside"

"Brother Song, the door is locked." Meng Yu pulled down the door and said. Gu Song glanced at Wu Zhenguo, who immediately handed over the door key with a slightly uneasy expression.

Gu Song grabbed the key and threw it at Meng Yu, and continued to say to Wu Zhenguo: "Boss Wu, we have already understood, your bookstore has been operating poorly, making ends meet, and is in danger of closing at any time. And recently, your mother-in-law's old illness has relapsed, and she needs a lot of medical expenses. In other words, you're short of money right now, right? ”

"So what?" Wu Zhenguo was a little incomprehensible, "What does this have to do with Yan Yiyi's disappearance?" ”

"Of course it does. Yan Yiyi was kidnapped, and the kidnappers demanded a ransom of 2 million yuan from her parents. That's enough money to help you get through the current situation, right? ”

"What did you say?" Wu Zhenguo's eyes widened again, and his body couldn't stop shaking with anger and excitement. "Comrade policeman, you can't just wronged good people. I am also a person with a daughter, how could I do such a crazy thing? I'll admit that I'm short of money, but I can sell my house, I can think of other ways to avoid turning myself into a kidnapper, right? ”

"Then let me ask you, on June 6th, why is the surveillance in your store not working?"

"I've already explained this to the officer surnamed Meng. The store's surveillance has been broken for more than a week, and even now I haven't found anyone to fix it. Anyway, I don't have much business in this store, so I don't need to prevent thieves, and I've been thinking about cashing the store to someone else recently, so I don't even bother with it. ”

"But it's also possible that you deliberately let the surveillance 'fail' during this period in order to facilitate your own crimes?"

"This ......" Wu Zhenguo looked embarrassed, a little speechless.

At this moment, he knew very well in his heart that his daughter's classmate Yan Yiyi's whereabouts were unknown after coming to his bookstore, and it was reasonable for him to be suspected by the police. It just so happened that during the period of the crime, the surveillance in the bookstore was broken, which made the police mistakenly believe that he was secretly playing ghosts, in order to facilitate the crime. It is a fact that his bookstore is not well run, it is a fact that he is seriously short of money, it is a fact that he was the last person to see Yan Yiyi, and it is a fact that he had the opportunity to attack Yan Yiyi...... All of these unfavorable factors almost at the same time point to a clear and clear answer: he is the murderer who kidnapped Yan Yiyi.

The more Wu Zhenguo thought about it, the more panicked he felt. At this moment, Meng Yu retreated from the utility room, and helplessly spread his hands at Gu Song and said, "Brother Song, there is nothing suspicious in it, except for ......" He paused for a moment and said with a smile, "Except for hiding a large number of pornographic books and magazines, I didn't find any clues related to the kidnapping case." ”

"Pornography?" Gu Song raised his eyebrows, and seemed to begin to wonder if this Boss Wu had any special habits.

Wu Zhenguo was afraid that they would misunderstand, so he quickly explained: "That's all the leftovers that were sold before." For a while, the anti-pornography inspection was strict, and I was afraid of being fined, so I hid those books and didn't dare to sell them anymore. ”

"Forget it." Gu Song pursed his lips, feeling bored. Tonight's search was just a routine affair, and he didn't have much hope at all. "Since we can't find any clues here, let's ask Boss Wu to go back to the bureau with us to continue to assist in the investigation."

"No, I can't go with you!" Wu Zhenguo's attitude suddenly became tougher. "I can't let Xiaoxue know that the police are treating me as a suspect in kidnapping Yan Yiyi, which has a very bad impact on me......"

Hearing this, Meng Yu sneered on the side and said, "Yo, do you think of your daughter at this time?" Then why didn't you think you were a father when you kidnapped someone else's daughter? ”

"Several police officers, I repeat, I am innocent, and Yan Yiyi's disappearance has nothing to do with me. You're looking for the wrong person. Wu Zhenguo was angry and anxious, and the muscles on his face twitched comically.

Meng Yu sneered and said, "We will judge whether we have found the wrong person or not, it's not that you can get rid of criminal suspicion with a few casual quibbles." ”

"You ......"

"Alright, you both calm down." Gu Song hurriedly interrupted their conversation, comforted Wu Zhenguo and said, "Boss Wu, I didn't say that Yan Yiyi must have been kidnapped by you. I just ask you to go back and assist in the investigation, if you don't have a ghost in your heart, then you might as well come with us. ”

"Brother Song." The young and vigorous Meng Yu was a little angry, and snorted and said, "What are you polite to this kind of guy with a human face and a beast's heart, just take it away." Yan Yiyi has been missing for more than 50 hours, and we don't have time. ”

"Then, do you still need to inspect the residence on the fifth floor?" Xiao Qin, who had not spoken for a long time, interjected leisurely.

Gu Song frowned and thought for a while and said, "His wife, children, and mother-in-law all live in it, and it is impossible to hide hostages." You call someone over and search the bookstore inside and out to see if there are any secret doors, dark rooms, or anything like that. ”

"Okay, I got it." Xiao Qin agreed, then took out his mobile phone and dialed his colleague's number.

"Please, Boss Wu." Gu Song made a very gentlemanly move, although he was smiling, his eyes were cold and sharp. Wu Zhenguo knew that he couldn't escape tonight's catastrophe, so he silently struggled in place for a while, had to give up resistance, sighed, and walked towards the police car parked in front of the bookstore.

"Dad, it's so late, where are you going?" Just when Wu Zhenguo got half of his body into the police car, a girl's startled voice suddenly came from not far away.

Wu Zhenguo was stunned, quickly got out of the car, looked at his daughter in a daze, and didn't know how to explain for a while.

"I see that you haven't come home so late, I'm worried about whether something happened in the store......" Wu Xueyao's voice became smaller and smaller, and the whole person was like a frightened little animal, and her frightened eyes wandered back and forth between several people.

"Xiaoxue, I'm ......" As soon as Wu Zhenguo spoke, Gu Song made a "stop" gesture at him, walked in front of the girl, squatted down, smiled softly and said, "Xue Yao, your best friend Yan Yiyi has an accident, you must want to find her, right?" ”

"Of course." The girl nodded vigorously, "I made an appointment with Yiyi to learn to paint together during the summer vacation, and my father bought me all the paint boxes." The girl glanced at Wu Zhenguo as she spoke, and a sweet and happy expression flashed on her face.

Gu Song continued: "Your father has some clues to solve the case, maybe he can help us find Yiyi." So tonight, we'd like to ask him to help catch the bad guys. ”

"Really?" The girl blinked innocently and looked at Wu Zhenguo with an inquiring gaze. The latter opened his mouth in surprise, and then said yes again and again. The girl relieved her heart, waved her hand to Wu Zhenguo and said, "Dad, you go early and come back early, and my mother and I will wait for you at home." ”

"Don't worry." Wu Zhenguo promised his daughter with a smile, and the warm and kind smile made Gu Song's heart tremble. No, something seems to have gone wrong. This person......
