The car entered the community and came to Li Yi's downstairs, and it took less than 50 seconds from the gate of the community to the downstairs.

Li Yi asked Qin Gang to drive around the wall slowly, paying close attention to the wall, in fact, he knew in his heart that after a typhoon and a rainstorm, nothing would be left.

While driving, Qin Gang also looked around, "This community is really quiet, and the air is good, but it is really not suitable for Ms. Lin, this place is obviously inferior to Lakeside, she should choose the villa area." ”

"That's what Zhu Happy thinks about, not her."

"I feel that Team Liu's intuitive recognition of you today is quite high, but unfortunately the case has been closed, if it can be a few days later, it will be good today."

Li Yi didn't think so, but some things were done in such a way that the nine bends and eighteen turns were done, as long as Team Liu didn't veto his idea, they could still work hard to squeeze out spare time and make a low-key visit.

All clues are accumulated bit by bit, just like the current 1503 case.

He trusts his instincts and, above all, his logical analysis.

"Don't go into the basement when the car is parked downstairs, leave your mobile phone number in the car." Li Yi said.

Qin Gang was puzzled, "Are you deliberately looking for some work for the community security guards?" ”

"Qi Guobin's car is parked downstairs, not in the basement, we will calculate the time when we go out later, I think it's about the same, but I have to confirm it myself."

Qi Guobin drove about 45 minutes from the unit to the community, and when he arrived at the scene, Ye Mengyin had already been killed, and perhaps he had seen the murderer in the car.

"Let's assume the scene and rehearse it once according to the three roles of A, B, and C, A is the murderer, B is Qi Guobin, C is the accomplice who cleaned up the scene, and you are Ye Mengyin." Li Yi said to Qin Gang.

Li Yi pretended to be a murderer, knocked on the door, and Qin Gang opened the door.

"Who are you, what do you want me to do?" Qin Gang grinned.

"Take your life."

Li Yi walked into the hall, and the two of them were messing around.

"Okay, you're giving me Shao's girlfriend."

"You don't believe it, when you are a golden pimple, you are married."

"Lie, I see traces of lies in your eyes."

"Nonsense, no."

"Why is that face red?"

"Refreshed."

"Why is it yellow again?"

"Cold-resistant wax."

After finishing the lines, both of them couldn't help laughing.

"Now we're entangled."

After Li Yi finished speaking, he found that there seemed to be something missing, and patted his head, "I forgot to bring a fruit knife." ”

"Brother, are you really coming?" Qin Gang said.

"Come here, eat me." Li Yi pulled Qin Gang to his side and made an upward stabbing motion.

Qin Gang pretended to fall on the side of the sofa against the door.

"There's a problem here." Li Yi said.

"What have you found?"

"Ye Mengyin died of excessive blood loss, the knife piercing is not too deep, whether it is no force or no force, the murder weapon pierced into the abdominal cavity, Ye Mengyin may still have the ability to survive."

"In principle, yes, but many times severe pain can cause the injured person to faint."

"But the desire to survive can also make many people endure pain." Li Yi said.

"In principle, yes, but in the end, it depends on the individual, and everyone's physiology and psychology are different."

Li Yi couldn't be sure if Ye Mengyin had this ability to suffer pain, he hoped that it was best not to, but immediately fainted, and finally died of blood loss. Otherwise, she might have watched the murderer, staring at her with a vicious and indifferent gaze in front of her eyes until she died helplessly.

Qi Guobin entered the community, and at this time, it was about 15 minutes away from the time when the technical team identified Ye Mengyin's death.

Qi Guobin went upstairs and pushed the door directly in, walked into the hall, and saw Ye Mengyin who fell on the side of the sofa, trembling and stepped forward to touch Ye Mengyin's hand, cold, at this time Ye Mengyin was on the verge of death, but it should not be officially dead, fear drove Qi Guobin to flee, and also left fingerprints and shoe prints.

Finally, the accomplices of the scene cleanup arrived.

Qi Guobin closed the door when he left, he had to use the key to open the door and enter smoothly.

At this time, Ye Mengyin was dead, he cleaned up room by room, first wiped the tables, chairs and benches, mopped the floor (to avoid blood stains), carefully tidied up the bed in the bedroom, collected hair, repeatedly flushed the bathroom, collected the sludge from the floor drain, rearranged the body, took away the mobile phone, wallet, murder weapon, and finally erased all traces on the door, and quietly escaped.

During the whole process, he completely ignored the presence of the cold corpse in the room.

Li Yi and Qin Gang finished performing this process, and it was already sunset, "This is a time-consuming and physically demanding job." ”

"You're just not used to it." Qin Gang didn't care.

"Yes, I'm not used to cleaning up the site, do you think it's the part-time workers who come up to clean up the site?"

"I think we made a mistake"

Qin Gang squeezed his eyes at Li Yi, "Your house is downstairs, when we come over, we will buy good food and wine, won't we start a fire at your house at this time."

"This mistake is irreparable, but I have cigarettes in my house, please?"

Qin Gang and Li Yi laughed together.

Li Yi opened the notebook and began to record in the notebook.

One: Taking away the mobile phone is to hide the traces, so the murderer or the accomplice who cleaned up the scene, one of them, must be someone Ye Mengyin is familiar with or even close to.

2: If Qi Guobin lies, from the past analysis of the confession, he may be the second person close to Ye Mengyin in the city besides Wei Hui, if so, he may be the first person to enter the scene and the murderer.

Three: If what Qi Guobin said is true, then he is the second person to enter the scene, then it was the murderer and the third person who committed the crime, and he happened to be a witness in the middle of the time difference.

Four: There must be a close connection between the murderer and the accomplice who cleaned up the scene.

Five: The person who cleans up the site must have a backpack or box, and always take away some cleaned and used items, such as towels and brushes, which are not heavy, but they are always an eyesore when they walk in the community with them in their hands, and they can clean up the scene so cleanly that they will not make such low-level mistakes.

Six: From the analysis of Ye Mengyin's death time and the time of the simulated scene cleanup, the murderer must have left at night, he walked very calmly, and he should not choose to leave through the gate.

Seven: the back of the community is a large piece of wild forest hill, the gate of the community is the ring road, because it has just opened, there are few pedestrians and not many cars, but you can't avoid the camera, unless you have been walking through the forest, but the black light needs some courage. The avenue leads to the highway to the right, and two kilometers to the left is a sports school in the city.

Qin Gang felt his stomach rumble open, "Let's go back, there is still a video to watch, I happened to eat something on the way, and my stomach was almost vacuum." ”

When entering the elevator, Li Yi subconsciously pressed the floor of his house, "What do you want to take?" Qin Gang asked.

"It's wrong, there's nothing to take."

Li Yi pressed the first floor again, and suddenly remembered the phone call haunting in his dream, which needed to withdraw the telecommunications work order, and there would be no time to wait for the construction personnel to come to install the phone at home for a while.

Driving out of the community and passing the road where fireflies fly, the earth quieted down after a scorching day, and the heat was constantly steaming.

"Has it rained?" Li Yi asked Qin Gang.

"Like, it's not big, we don't feel much in the house."

In the distance, maybe it's the dust in the air, maybe it's the water vapor that evaporates after the rain at night, faintly, a fog.
