Li Yi carefully recalled every detail of the cleaning he and Qin Gang had at the scene, he always had a pimple in his heart, nothing could be found at the scene except the corpse, and as long as any suspect could show alibi evidence, it would be difficult for them to prove the guilt.

Even if the suspects can't produce alibi evidence, they are still missing from the chain of evidence, although there is no clear suspect yet, and this question has always been haunting his mind.

Going to the scene to do the simulation is to discover the possible negligence of the criminals, to do a large-scale search of the woods between the community and the sports school, and also to find a trace of evidence related to the scene, but the items collected at present, after the classification of him and Qin Gang, do not seem to look like items left over from the near future, and there seems to be little hope in intuition.

Human evidence, physical evidence, and confessions, they can obtain two things to the greatest extent.

Perhaps, it is only psychologically possible to make a breakthrough from one aspect to each possible suspect, but first of all, to find this person.

Shao Guoqing is the only gain from this action around the sports school, how should he be defined, whether he is purely like the night before, just to make an appointment for a drinking party, or because of a specific need. In terms of setting, he meets half of the conditions.

Familiar with sports schools, has had a lot of contact with Ye Mengyin, and was a passionate suitor of her. has also followed Ye Mengyin, before she is ready to leave, the work will definitely be handed over in advance, and Shao Guoqing will definitely know, will he follow again?

If he tracks it again, he must know Ye Mengyin's current address, at least he can know which building she lives in in the community.

The reason why he went to the sports school on the 7th, and when he left, why he suddenly changed to a new car two weeks later, whether it was prepared or accidental, Li Yi repeatedly asked questions and answers in his heart, analyzing the entry point and possible answers to each question.

Of the two roles of the hypothetical murderer and accomplice, is he more in line with the role of murderer or accomplice?

Now this direction and Shao Guoqing's clue are not easy to come by, if you can't dig out more valuable clues, it is likely that your eyes will be blackened, and your efforts will be wasted, thinking of this, Li Yi smiled bitterly.

"Look at your eyebrows, ominous?" Qin Gang said.

"I haven't reached that point, think about it more and think about it, why do you think it is, I mean Shao Guoqing. He fits part of our premise, but he's in a car, and he's driving his own car, and he's not much of a thoughtful person in his past contacts, of course, just on the surface. What feels like a sudden thing is that he now has a new car. ”

Li Yi did some operations on the computer, "Yes, I almost forgot, his car No. 7 entered the sports school and never came out." ”

"Then we have three situations that we need to understand, one is the need for vehicle access information on No. 8; the second is to find out the situation from Lao Qiu, whether Lao Qiu has a car, and whether Shao Guoqing drove Lao Qiu's car away for some reason; The third is whether Shao Guoqing was alone that day or someone else went to the sports school with him, such as Bian Wei, he and Shao Guoqing are Lao Tie. ”

Li Yi thinks that Qin Gang's analysis is extremely good, and Shao Guoqing, the iron triangle, still needs to deal with them again.

In fact, the three of them are familiar with the sports school environment, and the most familiar is Lao Qiu, but he has no intersection with Ye Mengyin, and Shao Guoqing has the most contacts. But it is also possible for Lao Qiu to understand the Yijing of Lushan, and there must be a lot of movement when the new market is opened, and it is normal to watch the excitement in the vicinity. ”

Qin Gang suddenly slapped his thigh, "I remembered something." ”

Li Yi looked at him, waiting for his brain hole.

"Shao Guoqing We have asked three times, but his performance in the last two times is obviously different from the first time, we all have a feeling, is someone giving him a trick, right?"

The murderer and accomplice, this is the process of committing the crime set by Li Yi and Qin Gang, Qin Gang said this, and Li Yi immediately linked the two characters.

"Are you suspicious of him? In the ABC relationship we set, he and the person behind him are A and C. ”

Qin Gang nodded affirmatively.

"But there are contradictions."

Li Yi pulled the whiteboard in front of the two people and wrote: Crazy OR meticulous.

"The site is so clean, he should be a meticulous person." Li Yi said.

"There's no doubt about it."

"Familiar with the sports school, driving his own car into the sports school, will inevitably leave traceable clues, this is a bit crazy, he doesn't take the police seriously at all, will he take all the police for fools?"

Qin Gang was silent, he was also thinking about what Li Yi said, it was indeed a bit contradictory, Shao Guoqing had Lao Tie in the sports school, and it was a common thing to go to the sports school, but it happened to go on the 7th, and the Lushan Yijing case happened. If there is one thing that raises doubts, it may be that he changed to a new car shortly after the 7th, and his performance in the face of three inquiries before and after.

"He doesn't match our accomplice portrait, but in other set conditions, he meets to a certain extent, since he appears in our field of vision, we shouldn't let it go, anyway, the person in the portrait is not clear now, and we can't wait." Qin Gang said.

"Well, I've also been thinking about it repeatedly, the general direction we set is the movement trajectory between the sports school, the woods, and the community, and the small direction is the accomplice of the backpack and the hat. Because we assume that the accomplice must avoid the camera, but if he has other means of handling the items at the scene of the crime, he can avoid them deliberately. The general direction should not change, the small direction may be adjusted according to the situation, Shao Guoqing must go through it again, whether it is a routine inquiry, or a breakthrough according to the assumed direction, we must think about this first. Li Yi said.

"It's hard to analyze, he just happened to appear in the twists and turns in Ye Mengyin's case, and it just happened to be part of the portrait of the accomplice we set, and careful investigation is necessary. If we assume that he is an accomplice, then we must also assume that he is willing to take the risk to do so. Last time we went to his company, to see his outdoor product agent doing okay, the big boss is not a small boss is definitely a worry-free life, and he should not have a driving force for the benefit of pure money. If it's not for money, then his friendship with the murderer is really great, what kind of relationship does it have to be, it can't be a gang member, and there is no such so-called gang in Suishi. Qin Gang said.

"I have a lot to do with you."

"Count, but if you do this, I will definitely correct you with my own hands."

"Aside from the relationship of friends and interests, only brothers and fathers and sons can take risks for such things."

"Brothers and fathers? So what kind of family is this, it's a bit ruined. ”

Qin Gang felt that the possibility of Li Yi's analysis being true was extremely low.

Li Yi told Qin Gang a real case:

Somewhere, in a small city, a big family, two brothers, the elder brother is married, and they all live in the same yard as their parents. The younger brother killed someone, leaving traces, because it was a small place with no foreign population, in order to escape the police's biological extraction of men in the city, he went home after the crime and violated his sister-in-law, so he was detained and avoided biological extraction.

"No, it's weird, how did this case be solved later." Qin Gang sighed.

"It doesn't matter how the case is solved, I want to talk about this family." Li Yi sold Guanzi.

"Tell me, hurry."

"After my younger brother was detained, this mother was not happy, because she has doted on this little son since she was a child, delicious food, easy to use and easy to wear, and met the requirements as soon as possible, and of course developed a lot of bad habits."

"Getting to the point."

"On the second day of becoming a mother, she took the whole family, including my brother and sister-in-law, to the police station to make trouble, and asked for my younger brother to be released, on the grounds that family affairs were solved at home. The police station will definitely not agree to this ridiculous request, and when she is a mother, she forces her sister-in-law to admit that she has committed adultery with her brother-in-law, so she makes trouble at the police station every day, and she is not ashamed of what happened in her own family. ”

"I'm XXX, I took it, there is neither morality nor ethics, and the daughter-in-law who entered this family is also a tragedy."

"Yes, in life, many real things are often more ruinous than those seen in novels."

"Is there any possibility, these three people actually have nothing to do with each other, after the first person arrived, he killed Ye Mengyin, he was very panicked when he left, and he just wanted to leave quickly, so he didn't care if the door was not closed. After the senior arrived at the scene by appointment, he was also panicked, and after a short thought, he took his mobile phone and left. And the last person to come is Ye Mengyin's phantom boyfriend, the 7th is her birthday, they should spend it together, there is such an intimate relationship, this person can open the door with a key to enter, but he also found that the room has become a murder scene, in order to prevent him from being regarded as a suspect by the police, he cleaned up the scene, and then found an opportunity to leave covertly. ”

Li Yi was about to speak, "No, this is not in line with human nature, if this is the case, he should choose to call the police, I was just thinking nonsense, don't count." Qin Gang had already denied this idea.

"We are still in the established direction, and the birthday of 4.26 that you analyzed, since 087 is the birthday of August 7th, why not the last three directly 426 but 264?" Li Yi looked at Qin Gang.

"I've thought about this.,Computer you learn better than me.,The system date in the computer can be represented by 4.26 or 26/4.,The format of the two dates before and after is not uniform,I guess it's to prevent others from guessing it.,The password of the card can only be 6 digits.,There are no 64 days in February.,There are no 26 months in a year., It just so happens that Ye Mengyin's mobile phone memo has a 4.26 birthday record, and my analysis must be that she used her and her friend's birthdays as bank card passwords, these two dates are meaningful to her, and they are also easy to remember, of course, the date format has been changed a little, this is very reasonable, hehe, this also taught me a method. ”

Habitual thinking and brainstorming is a good thing, which is conducive to analyzing problems from more angles and looking for more clues and corroboration, which is what Li Yi taught when he was a teacher at the police academy. Don't be afraid of mistakes, many times, it's because of trial and error that you can find the right direction.

"How do we define Shao Guoqing, I draw a mind map." Qin Gang asked.

"A suspect who doesn't quite fit the portrait."
