After getting the list, the members of the task force took separate actions and stepped up the time to investigate the suspects in the list. Although there is a general direction of investigation, time is pressing, and it is not easy to quickly and accurately find the murderer who kidnapped Yan Yiyi among these two dozen people.

Just when the others started to get busy, Gu Song was still holding the list, thinking about a detail that He Weiqi had mentioned when he restored the incident. That overlooked sentence may be the key link that can connect kidnappings and shootings. In order to confirm some seemingly irrelevant information, Gu Song called Fan Cong, the main investigator of the "6.7 shooting case".

"Slept? I have a few things I'd like to confirm with you. ”

Fan Cong let out a confused "um" on the phone, yawning and complaining: "Dude, don't you look at what time it is, you came to disturb me as soon as I fell asleep......"

"I don't want to." Gu Song said apologetically, "But this matter is related to the life of a 10-year-old girl, so you can cooperate with me a little." ”

"What?" Hearing this, Fan Cong instantly sobered up and asked eagerly, "What's wrong?" How can I help? ”

Gu Song explained the general situation of the kidnapping case to Fan Cong in short language, and then explained: "We just got a list of suspects from the girl's father, and we found that Wang Chengyu, the victim of the shooting, was also inside. I suspect that he is the culprit who kidnapped Yan Yiyi. ”

"There must be some basis for that, right?" Fan Cong was suddenly interested. He knew that Gu Song's suspicions of anything were justified, and it was impossible to make hasty inferences just because he found a familiar name on the list.

"Sort of, but before I act, I'd like to ask you a few questions."

"Okay, you ask."

"Wang Chengyu is single now, and he shares a house with a male roommate in the Hongyun community, right?"

"Yes, that's right."

"At the time of the shooting, Mr. Wang's electric car was parked in front of a convenience store. Did he just come back from outside and was about to come home from shopping? Or have you just come out of the house and are you planning to go somewhere in the future? ”

"According to what we have learned, he had just come out of the house not long after the incident, and the elevator monitoring has a record."

"In other words, he's going to buy something at the convenience store in front of his house and ride his electric car to somewhere, right?"

"That's how it should be." Fan Cong replied with certainty, "If he just came out to buy something, there is no need to push the electric car out of the underground parking lot and park it in front of the convenience store." ”

"In addition to the electric car that was stolen by the robbers, does Wang Chengyu have any other means of transportation?"

"No, but he occasionally borrows his roommate's car and drives it. It is said that the two of them get along quite well. ”

"What is Wang Chengyu's financial situation? Do you know? ”

"All I know is that he used to be a salesman and didn't have a formal job when he was killed, so I don't know much about it. After all, for us, Wang Chengyu is a victim of the shooting, not a suspect, and we don't need to investigate his personal information in every detail. After a pause for a few seconds, Fan Cong suddenly remembered something, "Oh, by the way, after the shooting, only Wang Chengyu's sister rushed over from out of town, and his bedridden mother didn't know the news of her son's murder." I have the feeling that their family's financial situation should be problematic, but I can't guarantee it. ”

"Do you know what disease his mother had?"

"I don't know, but I can help you inquire."

"Last question, has Wang Chengyu been married before? Do you have small children at home? ”

"Huh?" Fan Cong was stunned for a moment, not knowing why Gu Song asked him this question, and replied in surprise, "Of course not." He works alone in R City, with no relatives, where did he come from. Why do you ask this? ”

Gu Song smiled and said, "Because before the crime, he bought a lot of snacks in the convenience store that only children love. When the robbers broke into the convenience store, the pile of snacks was scattered all over the cash register. Don't you think Wang Chengyu has long passed the age of eating those snacks? ”

"It seems a little strange to hear you say that......"

"So I suspect that the snacks were probably bought by him for some of the kids. Fan Cong, do you remember what Wang Chengyu said to the robbers before he was shot? ”

"I think about it, it seems to be a begging for mercy......" Fan Cong recalled for a moment, and suddenly exclaimed, "Ah, isn't it the sentence 'Don't kill me, I still have a child at home.'" 'It's hard to ......'"

"yes, that's it." When he first heard He Weiqi restore the scene of the crime, Gu Song didn't take that sentence to heart, and believed that others were the same. "If you look at the shooting alone, it's just an inconsequential remark. Regardless of whether Wang Chengyu has children at home or not, we will think that when he faced the gunpoint of the gangster, he said that sentence just to win the sympathy of the gangster and try to get the gangster to open up to him. But combined with all the information, especially when there is some overlapping information between the shooting case and the kidnapping case, we have reason to suspect that the child Wang Chengyu mentioned before his death may be Yan Yiyi, who was kidnapped by him.

The general story of the incident is likely to be as follows: On the evening of June 6, Wang Chengyu kidnapped Yan Yiyi in front of the bookstore near Jianshe Road Primary School, used transportation to move her to a hidden location, called Yan Yiyi's mother, and demanded a ransom of 2 million yuan from her.

On the evening of June 7, Wang Chengyu contacted Yan Yiyi's mother again, and the two sides determined the time and place of the transaction the next morning. At around 21 o'clock, Wang Chengyu originally wanted to buy some food for Yan Yiyi at the convenience store in front of his house and send it over. However, in the process of checking out, a gunman broke into the convenience store and pointed a gun to his head, and he was so anxious that he said, 'Don't kill me, I have a child at home.'" Trying to get the gangsters to spare his life. Unexpectedly, the gangster was ruthless, not only hit him in the eyebrows with a shot, but also snatched his electric car, so from that night on, Wang Chengyu never contacted Yan Yiyi's mother again.

For Yan Yiyi's parents, the sudden disappearance of the kidnappers made them very panicked. They thought the shooting had alarmed the police across the city and affected the kidnappers' trading plans, causing the kidnappers to abandon the deal or have already ripped their daughters up. But in reality, the kidnappers were not frightened into hiding by the heavily guarded police, but had already become the first victim of the shooting. If the situation is as I speculated, then Yan Yiyi should still be alive by now......"
