Shao Guoqing's car, nothing was found, Li Yi was not surprised, it must have been from the 7th to today, many days have already passed, if Shao Guoqing halally entered 1503 to take away the items, there is too much time to clean up the car, even if he does not change to a new car, under the effect of Zhang Jiajun's accelerator, drag back to the 4S shop, there will be no chance to leave traces.

But it's okay, by the way, I got to know Zhang Jiajun from the other side.

Zhang Jiajun's reputation in the 4S store is OK, impartial, about his good betting, basically colleagues know, fortunately he has never borrowed a penny from any colleague, which is also the best reputation of colleagues in the store for him.

However, Shen Zhibin is more talked about in the store, although no one has ever seen this Zhang Jiajun's old iron before, but this time, Shen Zhibin inserted a knife in his friend's ribs, which is famous in the store.

The second is Ms. Lin, the family member of the bitter master, first, the expenses beyond the car insurance are borne by herself, which has exempted Zhang Jiajun from a large financial burden; For the compensation for the deceased husband, only a symbolic 10,000 yuan was proposed, which was also a hot topic in the store.

Zhang Jiajun also has two elderly people in his family, his wife works in a clothing store, and the child is just in the first grade of primary school, if Shen Zhibin doesn't help him, the family will collapse 100%, at this point, Li Yi still admires Shen Zhibin.

"Their friendship is only 4 years at most, and it can be regarded as fate to this extent." Qin Gang said.

"Well, that should be Zhang Jiajun's luck."

Li Yi said this in his mouth, but he still had ideas in his heart.

"You seem to have something to say." Qin Gang saw that Li Yi's mouth was wrong.

"From the analysis of human nature, a person has a gambling habit, and the only person in the world who can forgive him and bear the debt for him, I think in addition to his parents, his own brothers may not be willing. Based on the two of us, I will lend you the money for your marriage. ”

"I recorded it, don't regret it." Qin Gang interjected.

"Don't interrupt, I will lend you the money for your poor medical treatment, and I will lend you the money to buy a house within my ability, but I owe a lot of gambling debts, and I won't lend you a single hair, this is reasonable, I think my friend has done it to this extent, it is already very glorious."

"What you said is right, then how to understand the friendship between Shen Zhibin and Zhang Jiajun."

"To put it bluntly, if someone bears debts for a gambling person like Zhang Jiajun, it means that Zhang Jiajun must still have his usable value. Although this is malice to speculate on human nature, it may be the truth. ”

"What do you think, Ms. Lin?"

These are two concepts, that is, Ms. Lin has a benevolent heart, so she can only understand it this way. Zhang Jiajun put it down first, our main direction is still 1503. ”

Li Yi opened the report sent by the technical team, the bottle of wine was blended wine, without any hallucinogenic or anesthetic ingredients, and was composed of grains, rice, potatoes, and agave.

Qin Gang came into the office with a glass of wine.

"This is what Lao Qiu brought from there? You're welcome to drink it. ”

"There is still a third of the wine bottle, I poured a glass out, the wine bottle is in the technical group, we also want to try this wine, whether it has such great power, this will definitely promote the analysis of the case."

Li Yi tried a small sip, and it felt mellow and natural, but it was very stimulating to the taste buds, and it did have a very strong rice fragrance, but from the perspective of intensity, it seemed that he could drink more than half a catty, not like a wine that could drink two people.

"I feel like it's between 50 and 60, and theoretically I can kill most of the bottles myself." Li Yi said.

"So confident, what is the composition of this wine."

Li Yi handed the report to Qin Gang, "Look at it yourself, different wines are blended with each other, I wonder if we should mix a bottle to try." ”

Qin Gang quickly glanced at the ingredients, took the cup and took a small sip.

"Well, it tastes good, give Team Liu a squeak, and we also stock up on it, and we can use it at dinner."

Li Yi didn't answer Qin Gang's words, blending wine, he thought in his heart, this kind of blending is often found in bars, but it will be mixed with a large amount of fruit juice to dilute the alcohol concentration, if it is completely blended with this high degree of liquor, it will be easy to get started, and people with poor alcohol will even be completely broken, this is an experience that is often introduced to him by a small person who often goes to bars.

Li Yi tasted wine just now, and the taste and smell are mainly the rich aroma of rice wine, but the taste buds are slightly stimulated, but it is also a reasonable thing to mix wine, and what kind of wine you like to drink is also a person's preference and freedom, but if you use this method to achieve a certain purpose, this technique is very hidden and will not show obvious traces.

Lao Qiu's retelling is basically the same as Shao Guoqing's statement, the wine is in a naked glass bottle, which Bian Wei brought to Shao Guoqing, according to Lao Qiu's recollection, he fell asleep not long after Shao Guoqing fell asleep. It was only half an hour at most, and there was a lot of wine left, and he also slept until dawn, so I don't know if Shao Guoqing, who was sleeping in the hall, had any other conditions, and his only feeling was that the wine was very strong. Could this be Ma Bianwei's blended up a long time ago? Qin Gang said.

"Tomorrow we will also find Bian Wei, and we will know as soon as we ask, there is one more detail."

"What details."

"After Shao Guoqing put down the wine, Lao Qiu asked him to go to the commissary downstairs to help buy two boxes of cigarettes, and he made soup in the kitchen, because the door of the takeaway house was always open, when he came up, Lao Qiu didn't know, Shao Guoqing was already there when he came out with the soup, this is what Lao Qiu himself said."

"Yes, there is no iron door downstairs, and the old-fashioned dormitory of the school is not installed."

Li Yi wrote on the whiteboard: The wine briefly left Shao Guoqing's sight.

Later, he wrote: the portrait of the accomplice, the school's surveillance, and the blending of wine.

"We are now in these three directions, the first two are consistent with our established goals, blending wine is new, and I wrote it out because of the three people who think about wine, two of them are more or less related to Li Yaling." Li Yi said.

"Is there a possibility that the accomplice did not enter from the sports school, he took a vehicle to get off at the Ring Road, went directly into the forest, climbed over the wall into the community, and when he came out, it was the same operation, and then left in the vehicle that responded." Qin Gang proposed a new idea.

Li Yi held his chin and thought carefully.

"If you don't want the murder case to be widely publicized, you can only turn around and respond to the accomplice. We drove through that section of the road, there were trees on the side of the road, in fact, there was no obvious reference location, the time to clean up the site was unpredictable, who waited for whom. The goal of the car is large, and the driver must be panicked if the waiting time is too long to stop on the roadside, and it is even more impossible to park in the woods; The accomplice came out first, hid in the woods and waited for the car, and there was no recognizable location on the side of the road for the driver to identify. The point is that the murderer has a poor psychological quality, which is not a good program. Besides, whether the car goes straight on the highway or turns around at a traffic light, it will definitely be photographed, which for a thoughtful person will definitely think, and I judge that he will not make such a choice. Li Yi elaborated on his thoughts.

Qin Gang took a sip of wine, "It also makes sense, the murderer's poor psychological quality is certain, otherwise he won't leave without closing the door, it's really not suitable for him to turn around and respond, and changing to someone else is equivalent to one more person knowing, and it's even more unsuitable." It's a plan, but it's also an option. ”

"Yes, it's still our established direction, sports school, woods, community, three points and one line. Now let's analyze how he bypassed the surveillance. ”

Li Yi continued to write: monitoring equipment specifications.

Qin Gang has inquired about the relevant information of camera monitoring on the Internet, the shooting distance of the ordinary 3.6-6.0mm infrared camera is about 40 meters, the camera 6-25mm can shoot 100 meters, and the above 25mm can shoot 150 meters, if it is a high-speed PTZ all-in-one machine, it can shoot 300 meters, of course, the PTZ all-in-one machine is a special equipment, and the school will not use this type of specification.

"We came out of the sports school today, from the restaurant with the back door to the teaching building, I carefully observed the perimeter, near the back door, the distance between the nearest cameras is about 80 meters, the ordinary 3.6-6.0mm infrared camera shooting distance is about 40 meters, the sports school is this specification, it is impossible to shoot. There is a camera in the school building pointing in this direction, but as long as you adjust the angle of walking, you can't shoot it either. Walk through the teaching building is the canteen, walk around the canteen without cameras, and then go all the way to the wall behind the school, there are 2 cameras along the way, both with an interval of more than 100 meters, to the wall, the perimeter and the cameras on both sides of the wall, the straight-line distance is not less than 50 meters. In other words, if the accomplice enters the sports school in this way and climbs over the back wall, there is a perfect route to avoid the surveillance in the campus. Outside the West Gate, from the door to the end of the food street, two cameras shoot in the middle, one in front and one behind, but this distance spans more than 200 meters, and the restaurant is out of the shooting range from both sides, so you don't need to deliberately avoid it, and you can't shoot it at all. ”

Qin Gang put down his wine glass, "Also, the restaurant starts at 11 o'clock in the morning and is open until about 11 o'clock in the evening, and the back door is actually basically open." It is mainly the school's staff and students who come in and out of the restaurant to eat, and if there is no gate, they have to go around the west gate. Of course, this door must be a privilege, and the restaurant is opened by the family of a certain leader on campus. The back door is not closed during business hours, and if it is closed, it may only be brought by someone when they enter and exit. Even if it's closed, if you want to enter the restaurant through the wall, you just have to knock on the door and someone will open it. ”

"Actually, that door just adds an easy way to get in and out." Li Yi said.

"That's right, as long as you know the inside and outside, you can enter the restaurant and enter the kitchen outside the school, and you will enter the school directly through this door. I asked the restaurant staff if they had any impressions of No. 7, but no one noticed who was coming or leaving through that door, and they couldn't remember it at all. Because the entry and exit of this door is a norm, no one cares. If we had gone in the right direction, we would have had a bump here, and I believe the suspect was never in the camera's range from the beginning to the end. ”

Qin Gang's words made Li Yi feel a sense of joy: Qin Gang became more and more meticulous and entered the state.

At the same time, it was like a bucket of ice water, drenched from Li Yi's head to the soles of his feet, in the direction he set, he couldn't paint a portrait of the murderer, there was a chill, and he frowned.
