He Jiahui took the deceased's shoes and returned to the forensic department again.

When Gao An saw He Jiahui, he was slightly startled, and then asked with a smile: "Why are you back again? Don't even think about going back on my sister's matter!"

"Let me show you something." He Jiahui handed the shoes directly to Gao An and said at the same time, "These are the shoes of the victim who fell from the building."

Gao An took the shoes and looked at them carefully. He soon saw the oil stains on the shoes, so he said, "This thing looks like some kind of oil stains, right?"

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

"

"So quickly help me check to see what the oil stains on the soles of the deceased's shoes are." He Jiahui said.

Gao An immediately took the shoes for testing, while He Jiahui just waited there. After waiting for more than half an hour, Gao An came back with the laboratory report.

"We have tested the components of the oil stains on the soles of the deceased's shoes. The main component is edible oil. In addition, there are amino acids, sugars, organic acids, proteins, vitamins, etc." Gao An said.

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

"Yes, it's vegetable soup." Gao An nodded, and then said: "The deceased should have accidentally stepped on vegetable soup before he was alive, but our forensic evidence did not find any residue of vegetable soup on the ground of the deceased's residence, including

Not even in the kitchen."

"I remember that in your forensic report, you calculated the path of the fall, right? Didn't you find the point of initial fall at that time?" He Jiahui asked immediately.

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

Gao An paused and then said: "After all, people are not dead objects. People can exert force and make movements. When jumping from a building, whether or not the force is used, the direction of the force, and even the movements and posture of the deceased in the air will all affect

to the final crash site,

This is also the reason why there will be certain errors in our calculations. Generally speaking, the higher the falling floor and the longer the falling path, the greater the error will be.

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

Based on the calculation of where the deceased landed and the direction of his body when he landed, he did not fall from the neighbor's balcony. If he had fallen from the neighbor's balcony, he would not have landed in that position."

"What about the height? Could it have fallen from the same location but from different floors?" He Jiahui asked immediately.

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

The floor height of the deceased's residence is 3.85 meters, and the height of the 12th floor where the deceased lived is between 42.35 meters and 46.2 meters, which is within an error of plus or minus three meters. So we believe that there is no problem with the initial fall point."

He Jiahui immediately produced his mobile phone and made some calculations, then said, "According to what you said, the starting point of fall is between 45 meters and 48 meters. If the error is three meters, it could be between 42 meters and 51 meters."

The highest point on the 11th floor is 42.35 meters, but it is impossible for the deceased to stand on the ceiling and jump down, so we can directly exclude the 11th floor. The 12th floor is the floor where the deceased was, which is what we identify as the fall point.

The height of the thirteenth floor is between 46.2 meters and 50.05 meters, while the height of the fourteenth floor is between 50.05 meters and 53.9 meters. These two floors also meet the range of 42 meters to 51 meters.

In other words, the real place where the deceased fell is most likely the unit on the 13th and 14th floors in the same location! It seems we have to go to the scene again!"

…

The crime team once again came to the community where the crime occurred. The security guard took them directly to the fourteenth floor in the elevator.

"Mr. Qian on the 14th floor is in finance. He works in a fund company. He is very busy at work and is rarely 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 also hired a Filipino maid." The security guard introduced, he obviously knew the owner's information quite well.

Knocking on the door, the one who opened the door was a Filipino maid. 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 to come out to receive them.

Mrs. Qian was a very petite woman. Facing a group of police officers, she asked weakly: "Sir, who are you looking for?"

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

So we want to go to your balcony, do some measurements, and collect information about your building to facilitate the investigation of the case, and we also ask Mrs. Qian to cooperate." He Jiahui said.

He Jiahui did not directly explain that he suspected that the deceased jumped from this floor. He was also worried that it would arouse the vigilance of the homeowner and destroy evidence.

Mrs. Qian had no doubts. She nodded: "Sir, please come in."

"Let's put on shoe covers to avoid soiling the ground." He Jiahui said and put on the shoe covers.

His real intention was not to worry about staining the ground, but to avoid damaging traces.

When he came to the balcony, He Jiahui looked at the surrounding environment. Different from the neatness on the twelfth floor, there were a lot of things piled up on the balcony of this apartment. There were children's toys, three boxes containing sundries, and

Several pots of flowers and plants.

"Mrs. Qian, you also like to grow flowers! This pot is growing really well." He Jiahui said, deliberately moving one of the flower pots and looking under the pot.

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

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

Gao An searched for evidence on the balcony, then shook his head at He Jiahui and said he found nothing.

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

After walking out of the room and coming to the elevator, Gao An reported: "Although the balcony on the fourteenth floor is a bit messy, no footprints with oil stains were found."

"There are usually two women in this household. Mrs. Qian is smaller in stature, and the Filipino maid cannot be counted on to push the deceased off the balcony." He Jiahui said, looking at the security guard, and asked: "We

Let’s go to D on the 13th floor and have a look! Who lives on D on the 13th floor?”

"The person living in Room D on the 13th 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 come back for a long time."

"How did you know?" He Jiahui asked.

"Yesterday, the tenant on the 13th floor called a moving company and moved everything inside. I saw that even the bed was dismantled and loaded into the truck. He probably won't be coming back to live in the short term," the security guard said.

replied.

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

"The tenants on the 13th floor said that this building is unlucky because of the death of someone, so they need to move out as soon as possible," the security guard replied.

"Then there's no need to leave in such a hurry, right? Even the bed has been moved, so you must have found a new place to live, otherwise there is no need to move the bed. But can you find a suitable place to live in one day?"

Thinking of this, He Jiahui ordered: "If you leave in such a hurry, there is something wrong with D on the 13th floor! Just call the locksmith expert to unlock it!"

Taking advantage of the opportunity to call the locksmith expert, He Jiahui continued to ask the security guard: "What kind of person is the tenant in D on the 13th floor?"

The security guard answered, "The tenant on D on the 13th floor is a young couple. The man's surname is Zhang and the woman's surname is Sun. They just live together and are not married yet."

"Do you even know whether someone is married or not?" He Jiahui asked with a smile.

"It's like this. One time I met that woman, I called her Mrs. Zhang, and she told me that they were not married yet." The security guard paused, and then added: "But I don't think the two of them are.

Looks like you can get married."

"How did you see it?" He Jiahui asked next.

"The relationship between them is not very good. When the two of them walk together, they are still separated by a long distance. They don't feel like a couple at all, but like strangers." The security guard continued to answer.

"Do you know what this tenant does?" He Jiahui asked again.

"Mr. Zhang said that he is a programmer, and he looks like a programmer. He wears glasses, is weak-mannered, and is not good at talking. As for Ms. Sun, I have not asked her what she does, but she

You are quite good at dressing up," the security guard said.

"You know how to dress up? What do you mean specifically? Are you 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 she has a different face. If she didn't wear makeup, I definitely wouldn't recognize her." The security guard said.

He opened his mouth and answered.

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

The locksmith opened door D on the 13th floor. It was indeed empty inside, and all the furniture had been removed.

Gao An went straight to the balcony and started collecting traces.

"Sir, I found that there are shoe prints on the guardrail of the balcony!" Gao An said.

He Jiahui walked over, took a look, and said, "This means that someone stepped on the guardrail. It was probably left behind when the deceased jumped from the building. Take it back and compare it with the deceased's shoes, and you should be able to confirm."

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

"Sir Gao, look at this, does it look like dried vegetable soup?" He Jiahui said, pointing to a puddle on the ground.

"I immediately collected evidence and compared it with the oil stains on the soles of the deceased's shoes." 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, asked: "The deceased does not live here. If he wanted to jump off the building, he could jump off the building at his own home. Why would he go to someone else's house and jump off the building? Could it be that he was kidnapped?

Someone threw it down?"

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

"Sir Ma, do you think that the decoration style here is very similar to the decoration style of the deceased's home on the 12th floor? I remember that the deceased's home was also decorated like this, right?" He Jiahui asked.

"The decoration is very similar, but this is normal. Many developers now sell houses that have been fully decorated. The owners do not need to decorate after buying it. Let alone two adjacent floors, it is an entire building.

, and the decorations are all the same." Ma Jun replied.

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