Chapter 121 Deciphering the means of committing the crime
He Jiahui took the shoe of the deceased and returned to the forensic department again.

Seeing He Jiahui, Gao An was taken aback for a moment, then asked with a smile, "Why are you back again? Don't go back on your word about my sister!"

"I'll show you something." He Jiahui handed the shoe to Gao An directly, and said at the same time; "This is the shoe of the deceased in the falling building case."

Gao An took the shoes and took a closer look. He quickly saw the oil stains on the shoes, so he said, "This thing looks like some kind of oil stains, right?"

In the next second, Gao An also realized the problem: "I remember that the balcony where the deceased jumped off was very clean. If there were oil stains on the soles of the deceased's feet before he jumped off the building, then the balcony couldn't be so clean! Could it be that the deceased didn't jump from his own balcony? "

"So hurry up and check for me, what is the oil stain on the sole of the deceased's shoe." He Jiahui said.

Gao An immediately took the shoes to test, while He Jiahui waited in place.After waiting for more than half an hour, Gao An came back with the test report.

"We have tested the composition of the oil stains on the soles of the deceased. The main ingredient in it is cooking oil, in addition to amino acids, sugars, organic acids, proteins, vitamins, etc." Gao An said.

He Jiahui thought for a while and said, "Judging from these ingredients, the soles of the deceased's shoes should be the vegetable soup produced during cooking, right?"

"Yes, it's vegetable soup." Gao An nodded, and continued: "The deceased should have accidentally stepped on vegetable soup, but our forensic evidence found no vegetable soup residue on the ground of the deceased's residence, including Not in the kitchen either."

"I remember that in your forensic report, did you calculate the fall path? Didn't you find the problem of the origin of the fall?" He Jiahui asked immediately.

"The initial fall point we calculated is in line with the location and floor height of the deceased. However, there will definitely be errors in the calculation of the initial fall point."

Gao An's voice paused, and then continued: "After all, people are not dead objects. People can exert force and make movements. When jumping from a building, whether or not to use force, the direction of force, and even the movement and posture of the deceased in the air will affect to the final crash site,

This is also the reason why there will be some errors in our calculations.In general, the higher the floor of the fall and the longer the fall path, the greater the resulting error.

The deceased lived in a high-end residential area, where the houses were relatively large. In order to ensure a certain degree of privacy, a certain distance was also designed between the balconies of two adjacent houses.

Based on where the deceased landed and the direction of his body when he landed, he did not fall from the balcony of a neighbor's house.If it fell from the balcony of the neighbor's house, it would be impossible to land in that position. "

"What height? Could it be that they fell from different floors at the same location?" He Jiahui asked immediately.

Gao An thought for a while, and answered, "This possibility cannot be ruled out. In this case of falling from a building, we calculated the starting point of the fall to be between 45 meters and 48 meters, and the error is plus or minus three meters.

The floor height of the deceased's residence was 3.85 meters, while the height of the twelfth floor where the deceased lived was between 42.35 meters and 46.2 meters, which was in line with the error of plus or minus three meters.That's why we think that there is no problem with the initial fall point. "

He Jiahui immediately took out his mobile phone to do some calculations, and said, "According to what you said, the initial fall point is between 45 meters and 48 meters, and the error of three meters is between 42 meters and 51 meters.

The highest point on the eleventh floor is 42.35 meters, but it is impossible for the deceased to stand on the ceiling and jump down, so the eleventh floor can be directly ruled out.The twelfth floor is the floor where the deceased was located, which is what we identified as the falling point.

十三楼的高度是46.2米到50.05米之间，而十四楼就是50.05米到53.9米之间，这两层也符合42米到51米的区间范围。

That is to say, the real fall location of the deceased is very likely to be the same unit on the [-]th and [-]th floors!Looks like we'll have to make another trip to the scene! "

……

The serious crime team came to the community where the crime happened again, and the security guard took them directly to the fourteenth floor by elevator.

"Mr. Qian from D on the [-]th floor is in finance. He works in a fund company. He is usually very busy with work and is almost never at home during the day. But Mrs. Qian should be at home. Mrs. Qian is an illustrator and usually works at home.

They have a child in kindergarten, a boy, and they have a Filipino maid. "The security guard introduced, he obviously has a better understanding of the owner's information.

Knocking on the door, it was a Filipino maid who opened the door, and He Jiahui immediately revealed his identity: "We are the police of the Regional Crime Squad."

The Filipino maid couldn't speak Cantonese, so she called Mrs. Qian out to receive them.

Mrs. Qian was a very petite woman. Facing a group of policemen, she asked weakly, "Sirs, who are you looking for?"

"Mrs. Qian, don't be nervous. The day before yesterday, there was a case of falling from a building in your community. I think you should have heard about it? The person who fell lived on the twelfth floor. The location is the same as yours, and it is also Block D.

So we want to go to your balcony, take some measurements, and collect information about your building so as to solve the case. We also ask Mrs. Qian to cooperate. "He Jiahui said.

He Jiahui did not directly explain, and suspected that the deceased jumped from this floor.He is also worried that it will arouse the vigilance of the homeowner and do things like destroy evidence.

Mrs. Qian didn't doubt it, she nodded: "Those sirs, please come in."

"Let's put on the shoe covers so as not to dirty the ground." He Jiahui said, putting on the shoe covers.

His real intention was not to worry about soiling the ground, but to avoid damaging the trail.

Coming to the balcony, He Jiahui looked at the surrounding environment. Unlike the clean and tidy one on the twelfth floor, there were a lot of things piled up on the balcony of this household.There are children's toys, three boxes for miscellaneous items, and several pots of flowers and plants.

"Mrs. Qian, you also like to grow flowers! This pot grows really well." He Jiahui said, deliberately moved one of the flower pots, and looked under the flower pot.

On the ground under the flower pot, there is a circle of soil traces, which is formed by the water mixed with soil flowing out after watering the flowers.

"It seems that these flowers and plants are not just arranged." He Jiahui thought to himself.

Gao An searched for evidence on the balcony, then shook his head at He Jiahui, expressing that he hadn't found it.

"Mrs. Qian, we have finished the measurement. Thank you for your cooperation. We will not disturb you." He Jiahui said goodbye.

After walking out of the room and reaching the elevator entrance, Gao An opened his mouth to report: "Although the balcony on the fourteenth floor is a bit messy, there are no footprints with oil stains."

"There are usually two women in this household, and Mrs. Qian is relatively small, and the Filipino maid is even more unreliable, and she is unlikely to push the deceased off the balcony." He Jiahui looked at the security guard and asked, "We Go to the thirteenth floor D to have a look! Who lives in this thirteenth floor D?"

"Room D on the [-]th floor is not the owner, but a tenant." The security guard replied.

"The rent here shouldn't be cheap, right? Those who can rent a house in this community must at least be white-collar workers." He Jiahui said.

The security guard continued, "Sir, the tenant on the thirteenth floor should not be at home now. He may not be back for a long time."

"How did you know?" He Jiahui asked.

"Yesterday, the tenants on the thirteenth floor called a moving company and moved all the things inside. I saw that even the bed was dismantled and loaded into the car. They probably won't be coming back in the short term," the security guard said. replied.

"Moving? Someone died the day before yesterday, so you moved yesterday?" He Jiahui frowned.

"The tenants on the thirteenth floor said that it is unlucky for people to die in this building, so they should move out as soon as possible." The security guard replied.

"Then you don't have to leave in such a hurry, right? If you even moved the bed, you must have found a new place, or you wouldn't need to move the bed. But can you find a suitable place in one day?"

Thinking of this, He Jiahui ordered: "Leaving in such a hurry, there is something wrong with D on the thirteenth floor! Just call the lock-picking expert to open the lock!"

Taking advantage of the gap between calling the lockpicking expert, He Jiahui continued to ask the security guard: "What kind of person is the tenant on the [-]th floor D?"

The security guard answered, "The tenant on the [-]th floor D is a young couple. The man's surname is Zhang, and the woman's surname is Sun. They are only living together and are not yet married."

"You even know if someone is married or not?" He Jiahui asked with a smile.

"It's like this. Once I met that woman. I called her Mrs. Zhang. She told me that they were not married yet." The security guard paused, and then added: "But I don't think they are the same. Looks like you can get married."

"How did you find out?" He Jiahui continued to ask.

"The relationship between them is not very good. When the two walked together, there was still a long distance between them. It didn't feel like a couple at all, but like strangers." The security guard continued to answer.

"What does this tenant do, do you know?" He Jiahui asked again.

"Mr. Zhang said that he is a programmer, and he looks like a programmer. He wears glasses, and his writing is weak and he is not good at talking. As for Ms. Sun, I haven't asked her what she does, but she People are pretty good at dressing up." The security guard said.

"Know how to dress up? What exactly do you mean? Wearing a famous brand?" He Jiahui asked with great interest.

"She wears heavy makeup all day long, and her outfit is different every day. Sometimes it's like changing her face. If she didn't wear makeup, I would definitely not be able to recognize her," said the security guard. Open your mouth and answer.

While the two were talking, the lockpicking expert had arrived.

The lockpicking expert opened the door of D on the thirteenth floor, and it was really empty inside, all the furniture had been evacuated.

Gao An went straight to the balcony and began to collect traces.

"He sir, I found out that there are shoe prints on the railing of the balcony!" Gao An said.

He Jiahui walked over to have a look, and said: "This means that someone stepped on the guardrail, and it is likely that the deceased left it when he jumped off the building. Take it back and compare it with the deceased's shoes, and you should be able to confirm it."

Afterwards, He Jiahui walked to the restaurant again, looked carefully at the ground, and called Gao An.

"Gao sir, look here, does it look like dried vegetable soup?" He Jiahui pointed to a puddle of marks on the ground.

"I'll collect evidence immediately and compare it with the oil stain on the sole of the deceased's shoe." Gao An nodded.

He Jiahui looked around and said, "There are shoe prints and oil stains, the deceased should have jumped from the balcony on this floor."

At this time, Ma Jun, who had been silent all this time, asked, "The deceased didn't live here. If he wanted to jump off a building, he could jump off in his own home. Why did he jump off a building in someone else's house? Could it be that he was forced to jump off the building?" Someone threw it down?"

"If it was thrown down by someone, then there should be signs of struggle or struggle on the body, but the forensic report did not mention these." He Jiahui said, looked around, and frowned fiercely.

"Ma sir, do you think that the decoration style here is very similar to the decoration style of the deceased's house on the [-]th floor? I remember the decoration of the deceased's house, right?" He Jiahui asked.

"The decoration is very similar, but this is normal. Many developers now sell houses after decoration. After the owner buys it, they don't need to decorate it. Let alone two adjacent floors, it is a whole building , and the decoration is the same," Ma Jun replied.

He Jiahui pointed to the ceiling lamp again: "But even the ceiling lamp is the same!"

"Well-decorated, the lamps, sinks, and even toilets are all the same." Ma Jun replied.

"No, I was at Mrs. Qian's house on the fourteenth floor just now, and I saw the ceiling lamp in their living room, which is different from the one here." He Jiahui thought about it carefully, and then said; "And the decoration style of their house is also different from here .”

Ma Jun recalled it, and said, "You reminded me so much, and I remembered that the decoration of their house is indeed different from here. Did the ceiling lamps be replaced on the fourteenth floor?"

"I have a bold guess now." He Jiahui took a deep breath, and then ordered: "Go and check, which moving company came here yesterday!"

……

The management of this high-end community is relatively strict, and the moving company is registered when it enters and exits. The police quickly found the moving company yesterday.

He Jiahui and Ma Jun came to the moving company and found several masters who went to move yesterday.

I saw He Jiahui took out a few photos, handed them to the moving master, and said at the same time; "Several masters, please confirm whether you moved to the unit you went to yesterday."

One of the moving masters took the photo, glanced at it, and nodded: "Yes, it's this one!"

"Master, please take a closer look." He Jiahui said.

The moving master looked carefully again, and still nodded with confirmation: "That's right, it's this one, I remember it's D on the [-]th floor! This sofa and this coffee table were all packed by me, no would be wrong."

Another master next to him also pointed to the photo in his hand, and said, "I pushed the refrigerator down with a cart. It's this one, that's right."

"I remember this cabinet. The paint on the corners is a little bit off. I also asked the owner if I need to protect it when I pack it. The owner said it's okay." The third master said.

"Thank you a few masters." He Jiahui took back the photo and thanked him at the same time.

Ma Jun next to him asked, "Didn't the thirteenth floor D be vacated? Why do you have photos there?"

"Look where are these photos." He Jiahui handed the photos to Ma Jun.

Ma Jun took the photo, looked down, and was shocked: "Isn't this a photo of the deceased Wang Hai's family?"

"That's right, these photos are the photos of the deceased's residence taken by the forensic department at that time. But these movers said that these are the photos of the family they moved yesterday.

This shows that the deceased's residence on the twelfth floor D is exactly the same as his upstairs thirteenth floor D, not only in the decoration, but also in the furniture! "

He Jiahui said, with a confident smile on his face, and continued; "The murderer really knows how to play tricks, but his method of committing the crime has been deciphered by me!"
