Sometimes friendship is like this, it comes quickly, it is good and faster, when there is a man between two women as a topic, the distance between them is shortened a lot in an instant, and when the chubby Dabai joins the two people, Park Jingyan's eyes suddenly can't be shifted, and the appearance of holding the big white cat is not much different from hugging her son.

Wang Dong was forced again, originally to prepare food for a woman and a cat, but now he has to add another one, and the reception banquet specially found a local flavor restaurant in Qingyang, but Park Jingyan had to order a fish alone and bring it back to Dabai, saying that it was a meeting gift for it.

What kind of meeting gift, that is the money spent by Lao Tzu. Wang Dong stared at Da Bai, who was intoxicated and eating fish, and reluctantly retreated from the room after a while.

Happy days are short-lived, when Wang Dong took Park Jingyan to the reference room the next day and put the file in front of her, Park Jingyan finally understood why Wang Dong didn't tell her the content of the case yesterday, although Park Jingyan, who has always had a strong sense of justice, did not choose to be a policeman after graduation, but her inner conscience was calling her, if it was said that at the beginning, she was ready to help Wang Dong, but now, she has taken this case as her own business.

"What are you going to do?" Park Jingyan closed the first file, wiped the tears that remained in the corners of her eyes, and asked Wang Dong.

"I want to read all of this first, and then summarize the things that I think are important, keep them on the computer, and then ......"

Before Wang Dong finished speaking, his words were interrupted by Park Jingyan a little rudely, "That's too slow, even if the two of us don't want to finish reading so many materials for a few months, there should be a faster way." Park Jingyan began to think about it, the murderer's method is actually very simple, and he also left some evidence at the scene, such as his blood type B, but with such a large crowd base, how can you know who is blood type B.

"I think I know where to start." Park Jingyan opened her mouth coldly, so much so that she shocked Wang Dong, she could think of a way so quickly, didn't she compare herself to nothing.

"Where to start?" Wang Dong asked with some excitement.

"You're so stupid, haven't you heard the saying that we are standing on the shoulders of our predecessors, ask?"

Wang Dong blinked his eyes and explained in a low voice, "It's standing on the shoulders of giants." ”

"Where there are giants, now there is only one predecessor, first eliminate the methods they have used, and the rest may be correct." Park Jingyeon stood up as she said and walked towards the front of the reference room.

After a while, Qiu Guoqiang was invited by her, sat down and looked at Park Jingyan and Wang Dong, and said directly: "If you don't know anything, just ask." ”

Park Jingyan was not polite, she really couldn't see the end of so many files, so she first had to eliminate a part of the people who no longer had any suspicion, and what methods were used by the police back then, and she naturally wouldn't bother to do it again.

Eight years ago, now in retrospect, but as if vivid, Qiu Guoqiang was brought back to the day eight years ago by Park Jingyan's words, recalled a little and muttered: "It was about 11 o'clock in the morning on April 28, the team received a call from 110 to the police, three little girls were killed in the abandoned cave, less than five minutes, all the criminal police at home immediately dispatched, when I rushed to the ditch, I saw this scene......"

The old man picked up a panoramic photo, the cave above was probably clearly visible, but the vicinity of the cave door was full of thorny branches, and there was no difference between the inside from the outside, but in the next one, he could already see the body of the little girl in the house through the gap in the branches.

"We had a quick meeting at the site, thinking that it should be done by the nearby villagers who went to the ground, but the area of the river ditch is too extensive, and almost all the surrounding 14 natural villages have land here, so we first focused on the people who went to the ground yesterday."

"It took us a week just to visit these villages, and as time went on, people's memories dropped a lot, and even they themselves remembered confused."

"People in the village are also mobile, and some of them go to the city to work after they are busy with their farm work, and it is uncertain when they will leave or when they will be at home."

"Suspects appear every day, but none of them fully match the characteristics of the murderer."

"I believe that this murderer is in this full file, but there is no way to find him."

“……”

The data room was very stuffy and quiet, and the voice of the old policeman echoed in the room like this, Wang Dong and Park Jingyan both felt the heavy sense of responsibility on their shoulders, visiting this road is almost a dead end, how to dig this person out.

After Qiu Guoqiang finished speaking, he left, Wang Dong and Park Jingyan fell into thought, and after a while, Park Jingyan spoke first.

"Wang Dong, have you ever thought about starting with the character of the murderer?"

Nature? Wang Dong was a little surprised, looked at Park Jingyan curiously, and waited for her next words.

"In your opinion, what kind of person should this murderer be?" Park Jingyan threw the topic to Wang Dong again.

This question is a good question, take the murderer's character as his flesh and blood, first build a general framework in his heart, and then fill in his character step by step, the fuller the image of this person, the easier it is to find this person, Wang Dong thought for a while, and determined: "First of all, he should be a person with a little distortion in his heart, his family may not be complete, and it is likely that he has never been married, or he is simply a bachelor." ”

"Judging from the fact that he can control three little girls alone, he must have a lot of strength, in addition to farming, maybe he will also work in the city."

"The place where he lives may not have any connection with the three little girls' family, but on the day of the incident, maybe the three children offended him in some words, such as saying 'lame', 'blind', these insulting words."

"Fools?" Hearing Wang Dong's words, Park Jingyan's eyes suddenly lit up, and the word fool blurted out.

Idiot? Wang Dong thought about it, this is really possible, because fools are indeed a little simple-minded, and such people often do not have a very happy family, and it is also possible to have great strength, being said to be a fool, and it is true that they will explode in some cases, but will fools cover the entrance of the cave with branches?

Anyway, this is also the first clue that the two people have studied, and the case finally has a clear direction to search.
