◎Chapter 2    The female corpse hanging in the air

The special case team asked Officer Zhou to convene police officers and hold a case press conference in the conference room of the building. Unlike in the past, Professor Liang did not analyze the case and arrange tasks, but instead gave everyone a puzzle first.

This question is also a crime reasoning test question for FBI (FBI) in the United States. Only if you can answer it correctly within one minute will you be admitted to FBI.

The enthusiasm of the police officers in the conference room was mobilized, and everyone was eager to try and seemed very excited.

FBI test question: An old man in a wheelchair took the elevator downstairs. There was no one in the elevator, only the old man himself. But when he got downstairs, the elevator door opened and people found that the old man was dead and a short sword was inserted on his back. How did the murderer do it?

The police officers present talked a lot, saying that there was no murderer in such a small space as the elevator, but how to explain the deadly sword?

The policeman in the conference room could not give a reasonable answer even if he wanted to break his head. The time limit was about to come.

Baozhan blurted out: using the elastic rope and the downward force of the elevator, it was a way for the murderer to kill people without being on the scene.

Everyone suddenly realized that a police officer asked, how did the murderer determine the location of the elderly person in the wheelchair?

Bao Zhan explained: The person in the wheelchair must be close to the elevator button, and the murderer's dagger aims in that direction. On the handle of the dagger, the murderer connected a very elastic rubber rope in advance, passing through the air-changing hole of the elevator, and the other end of the rubber rope is tied to a fixed object above the elevator shaft. When the elevator goes down, the rubber rope will extend as the elevator descends, and the length reaches the limit, and the rubber rope will be tightened and broken. Because it has elasticity, the dagger will shoot out like a bow or an arrow, killing the victim.

Professor Liang nodded and praised: The answer is correct. Next, I will not tell you what we are looking for, and you can guess it.

Bao Zhan volunteered: There must be traces left by the murderer in the elevator shaft or the computer room at the top of the elevator. I will definitely find it, but I don’t know what kind of rope, steel wire, nylon rope, or carbon fiber textile rope the murderer used?

Professor Liang said: Let’s study the neck first.

Su Mei took out a prepared anatomical picture of the neck. The structure was clearly defined. The outermost part was the skin, the muscles and lymph nodes were under the skin, longitudinal blood vessels and nerves on both sides, respiratory and digestive tracts in front, and spine behind the fascia. The neck was very fragile, with a lot of soft tissue, with only one bone, with the neck of the spine as the pillar. There are ligaments in the middle of the annular cartilage of the spine. The executioner aimed at this position when beheading his head, and he could easily chop off the head.

The special case team analyzed the entire homicide process in detail.

The wound of the deceased is in the subjandal triangle, and only the power of a mechanical force can tear the head off alive. Suppose the murder tool is steel wire, the steel wire covers the head, and the other end is tied to a place above the elevator shaft. Through the elevator, this machine produces huge force. The elevator continues to descend. First, the deceased is hung high, with its head on the top of the elevator, the steel wire tightens, and it is tied into the neck, and it is tied into soft tissue. The first splash point of the deceased's blood appears at the top of the elevator, and the steel wire is tied into the ligament of the spine, which is also a very fragile position in the neck bones. Then, the head is broken by the steel wire, and the steel wire quickly sinks into the vent hole of the elevator and disappears.

The entire murder process was very fast and was completed almost in an instant.

Because it was an instant force, although there were traces of tearing on the skin on the deceased's neck, the entire wound was very neat.

Then, based on the blood splattering trajectory and distribution chart, it can be determined that the deceased has been standing after death. The steel wire cuts the head behind him. The deceased's corpse is cramped and stiff, falling from the air. The headless corpse falls into the elevator and shakes slowly for two times, but never falls.

The headless corpse was standing in the elevator, with blood spurting out from his neck like a fountain, splashing all over the elevator walls.

Professor Liang said: The murder rope is very thin, with super strength and elasticity, and is at least as high as two floors.

Officer Zhou asked in confusion: The wire rope has not been found yet, how do you know the length?

Professor Liang said: The deceased Wen Xiaowan took the elevator on the 42nd floor. After entering the elevator, she must press the button on the first floor. The murderer should have been in the elevator at that time. He used steel wire to cover the deceased's head, tied his hands behind his back, and left on the 41st floor. The witness was on the 40th floor, and the mother and son, who lowered their heads and tied their shoelaces for the child, but did not see a scene in the elevator. The child saw a person hanging in the air, which means that the length of the rope was at least as high as two floors.

Hualong added: The child must not see the corpse hanging in the air. The victim may not have died at that time, but was just hanging in the elevator, struggling, and his legs were crossed back. This is also the reason why the child said that the sister had no legs. Then, the elevator came back and witnesses saw the standing corpse.

Officer Zhou asked a question: It only takes a few seconds from the 42nd floor to the 41st floor. The murderer could not tie the victim's hands and put them around his neck in such a short time.

Professor Liang said: This question cannot be answered yet, and the murderer's time of committing the crime is still a mystery.

Before the meeting ended, Professor Liang assigned a task. Bao Zhan carefully inspected the elevator shaft to find the tools and traces left by the murderer; Su Mei visited colleagues in the company where the deceased was located to understand the relevant situation, especially to grasp the people who had conflicts with the deceased; Officers Hualong and Zhou were responsible for investigating the left-behind personnel in the building at the time of the incident, focusing on the elevator control room and those who knew that the deceased worked overtime, and listing a detailed list.

Professor Liang reminds everyone to work carefully, and the murderer's name is likely to be hidden in this list.

Everyone took their own responsibilities and started their work soon.

The incident occurred on Friday, and two days later, employees of various companies in the building started working.

A female editor who worked overtime until late at night was killed in the elevator, her head broke, but her body was still standing. This horrible bad news came, like a blowout, and colleagues at the publishing company where the deceased Wen Xiaowan were all shocked. Everyone was unwilling to work, and three employees submitted their resignation reports that day. They had to take the elevator to and from get off work every day, and they felt very scared when they saw the elevator where the crime occurred. I believe that every colleague would have psychological shadows for a long time.

Su Mei interrogated the editor-in-chief of the publishing company: Wen Xiaowan's boyfriend is among the three resignations, right?

The editor said: Yes, publishing and editors change jobs and personnel transfers are all very normal.

Su Mei said: I think it is more related to this case. Do your company have any competitors?

The editor-in-chief said: The competition is very fierce, and every publishing company is almost our competitor, and the Forty Floor is a cultural company.

The editor-in-chief briefly introduced that although their publishing company and the cultural company on the 40th floor were both in the same building, there was a legal lawsuit [31      Fast Update] dispute in the end, the cultural company lost the case.

Su Mei used a pen to record the editor's words, and then asked Wen Xiaowan's boyfriend. His name is Yang Zi, and Wen Xiaowan is a colleague, a book planning and editor, and has done many suspense books. After the incident, the police went to his residence to do interrogation records, but found no doubts.

When Yang Zi was asked, he was very calm. His attitude was that this matter had nothing to do with him, and he and Wen Xiaowan had broken up.

Su Mei reminded: You only broke up for a week. My colleagues confirmed that you had a good relationship before, but they had a big fight when they broke up.

Yang Zi tilted his head to the side and said in a plain tone: Isn’t it the case for lovers to break up?

Su Mei said: Your eyes were a little red and swollen. You can tell that you had cried. We found out that you had given her a scarf.

Yang Zi glanced at Su Mei, lowered his head, and his tears flowed out again.

Yang Zi told Su Mei that before breaking up, Wen Xiaowan straightened her hair and had ion perm. She didn't dare to sleep at night, for fear of crushing her hair.

He knew a little trick, putting a gauze scarf or silk on the pillow, so his hair would not deform easily after getting up, so he gave her a silk scarf.

Su Mei said: It seems that you have a good relationship, but there is a passage in your online log, I'll read it-

Every time I fall in love is my first love. It is impossible to love someone for the rest of my life. There are charming and beautiful women in the world. I always have to appreciate different women, feel different love, have passionate love, unforgettable feelings, and have warm attachment. This way, I will not be wasted. The moldy and bubbly pork is delicious, why should I eat one dish for the rest of my life?

Yang Zi interrupted Su Mei impatiently and said: This is my view of love, what's wrong?

Su Mei said: Did you write it in the log deliberately anger her?

Yang Zi raised his tone and said: I annoy her. Xiaowan is a woman who is too jealous and is jealous every day. When I see the photos of the beautiful girl, she has a quarrel with me. She also needs to check my mobile phone text messages. I am not allowed to do this or that. I am so annoyed that I just broke up.

There was no progress in the investigation of Hualong and Officer Zhou. The property management department of the building has several working groups: the safety group, the maintenance group, the sanitation group, and the water and electricity group. When the elevator murder occurred, there were several night duty personnel in each group in the building. There were originally two on-duty personnel in the elevator monitoring room, but on-duty personnel did not install surveillance on the night of the incident, and the two on-duty personnel asked for leave and left. The two security guards in the safety team inspected at night, but did not find any abnormal situations.

Officer Hualong and Officer Zhou asked each of them, asking the staff on duty to write down what they were doing at the time of the incident and their relationship with the victim.

Wen Xiaowan looks average, but she has a hot body, fashionable clothes, and has flowing hair. From the back, her back looks very charming. The autopsy results show that she has not been sexually assaulted. No one on duty at night knows her, and only a few people have some impression of her.

Bao Zhan first conducted a careful investigation of the elevator machine room. There were traction wheels and guide wheels in the elevator machine room, and no traces of steel wire hanging were found on the base. Bao Zhan was a little disappointed, and then inspected the bottom of the elevator shaft, hoping to find murderous weapons such as wire ropes, but found nothing except garbage.

When Baozhan was almost giving up, he found a hanging point on the guide rail bracket at the top of the elevator shaft. The friction marks were very new and the anti-rust paint had peeled off. Obviously, it was too heavy hanging on this point, and it seemed that this was the place where the wire rope was tied.

However, Bao Zhan had a new doubt: Where did the murderer enter the elevator shaft?

There are only two places:

1. In the elevator room, you can use a triangle key to open, and there are all keys on duty.

2. In the elevator, open the car top trap door, and the murderer climbs to the top of the car, and can also tie the steel wire to the guide rail bracket.

Although no killing tools such as wire ropes were found, Baozhan found something strange in the trash can.

Bao Zhan said: I checked the trash cans at the elevator entrance of the 42nd floor, 41st floor, and 40th floor, hoping to find the murderer thrown away the tool. I found a strange thing in the trash can. We often see this kind of thing, but now it looks very strange.

Hualong said impatiently: What is it? From now on, you will just say that I annoy you the most insincere.

Su Mei smiled and said: Xiaobao has always been very rigorous, what exactly is it?

Bao Zhan took out a bag of evidence and said: A strange banana was wrapped with tape on it, and it was hollow inside.

Professor Liang said: Xiaobao, which floor did you find it?

Bao Zhan said: The trash can on the 41st floor seems to have not been cleaned for at least two days.

There was a banana in the transparent evidence bag. The peel was complete and the inside was hollow. Strangely, there was tape wrapped around the banana.
