◎ Chapter 2 The Hanging Female Corpse

The special case team asked Officer Zhou to gather the police officers and hold a press conference in the conference room of the building.

This question is also a criminal reasoning test question from the FBI (Federal Bureau of Investigation), and if you can answer it correctly within one minute, you will be admitted to the FBI.

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

FBI test question: An old man in a wheelchair took the elevator downstairs, the elevator was empty, only the old man himself, but when he got downstairs, the elevator door opened, and people found that the old man was dead with a short sword stuck in his back, how did the murderer do it?

The police officers present had a lot of discussions, the elevator is such a small space, there is no murderer, but how to explain the deadly sword?

The police officers in the conference room couldn't give a reasonable answer if they tried to break their heads, and the one-minute time limit was approaching.

Bao Slash blurts out: Using the downward force of the bungee rope and the elevator to fire a short sword, this is the killer's way of killing in his absence.

Everyone suddenly realized, a police officer asked, how did the murderer determine the location of the wheelchair old man?

Bao Shu explained: The position of the wheelchair person in the elevator must be close to the elevator button, and the murderer's short sword is aimed in that direction. On the handle of the short sword, the murderer had previously attached a very elastic rubber rope through the ventilation hole of the elevator, and the other end of the rubber rope was tied to a fixed object above the elevator shaft. When the elevator goes down, the rubber rope will elongate as the elevator descends, and when the length reaches the limit, the rubber rope will be taut and broken, because of its elastic force, the short sword will shoot out like a bow or arrow, killing the victim.

Professor Liang nodded approvingly: The answer is correct, what we are looking for next, I don't say, everyone can guess.

Bao Chu took the initiative to ask: There must be traces left by the murderer in the elevator shaft or in the machine room at the top of the elevator, I will definitely find it, but I don't know what kind of rope the murderer used, steel wire, nylon string, or carbon fiber textile rope?

Professor Leung said: Let's start with the neck.

Su Mei took out a prepared anatomical diagram of the neck, which was clearly structured. The outermost part is the skin, under which are the muscles and lymph nodes, on both sides there are longitudinal blood vessels and nerves, in front of which there is the respiratory tract and digestive tract, and behind the fascia is the spine. The neck is fragile, with a lot of soft tissues and only one bone, with the neck of the spine as the pillar. The cricoid cartilage of the spine has ligaments in the middle, and the executioner can easily cut off a person's head by aiming at this position when cutting off the head.

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

The wound of the deceased was in the submandibular triangle, and only mechanical force could tear the human head alive. Suppose the killing tool is a steel wire, the wire is lassoed around the human head, and the other end is tied somewhere above the elevator shaft, and through the elevator, this machinery generates a tremendous force. The elevator kept descending, first hanging the deceased on a high place, the head was on the top of the elevator, the steel wire was tightened, strangled into the neck, and the soft tissues were strangled into the first splash point of the deceased's blood appeared at the top of the elevator, and the steel wire was strangled into the ligament of the spine, which was also a very vulnerable position in the neck bone, and then, the human head was strangled by the steel wire, and the steel wire quickly sank into the ventilation hole of the elevator and disappeared.

The whole killing process was quick, almost instantaneous.

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

Then, according to the blood splash trajectory and distribution map, it can be determined that the deceased has been standing after his death, and after the steel wire broke the human head, the deceased's body spasmed and stiffened, and landed in the air, and the headless body fell into the elevator, shaking twice and never falling.

The headless corpse stood in the elevator, blood spurting from its neck like a fountain, splattering all over the walls of the elevator.

Professor Leung said: "The killing rope is very thin, has characteristics such as super strength and elasticity, and is at least as high as a two-story building.

Officer Zhou asked puzzledly: 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, and after entering the elevator, she must have pressed the button on the first floor, and the murderer should have been in the elevator at the time. The witness was on the 40th floor, the mother and son, the mother lowered her head to tie the child's shoes, 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 is at least two stories high.

The child added: What the child saw was definitely not a body hanging in the air, and the victim may not have died at that time, but was just hanging in the elevator, struggling, and struggling to stilt his legs backwards, which is why the child said that the sister had no legs. Subsequently, the elevator came up again, and witnesses saw the standing corpse.

Officer Zhou raised a question: Time, from the 42nd floor to the 41st floor, only a few seconds, it is impossible for the murderer to tie the victim's hands behind his back and put his neck around his neck in such a short time.

Professor Liang said: This question cannot be answered at present, and the time of the murderer is still a mystery.

Before the end of the meeting, Professor Liang assigned the task. Bao Chu carefully surveyed the elevator shaft to find the tools and traces left by the murderer; Su Mei visited colleagues in the deceased's company to understand the relevant situation, especially to grasp the people who had conflicts with the deceased; Officers Hua Long and Officer Zhou were responsible for investigating the people left behind in the building at the time of the crime, focusing on the elevator control room and the people who knew that the deceased was working overtime, and made a detailed list.

Professor Liang told everyone that the work must be meticulous, and the name of the murderer is likely to be hidden in this list.

Everyone took their responsibilities and got to work soon.

It was a Friday, and two days later, the employees of the various companies in the building started work.

A female editor who worked late into the night was killed in an elevator with her head broken, but her body was still standing. When this terrible news came, it was like a frying pan, and the colleagues of the publishing company where the deceased Wen Xiaowan worked were very shocked, everyone had no intention of working, and three staff members submitted their resignation reports on the same day. They have to take the elevator to and from work every day, and they feel very frightened when they see the elevator where the crime occurred, believing that every colleague will have a psychological shadow for a long time.

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

The editor-in-chief said: Yes, it is normal for publishing editors to change jobs and staff turnover.

Su Mei said: I think it is more related to this case, do you have any competitors in your company?

The editor-in-chief said: The competition is fierce, almost every publishing company is our competitor, and the 40th floor is a cultural company.

The editor-in-chief briefly introduced that although their publishing company and the cultural company on the 40th floor worked in the same building, due to competition, there had been a legal dispute before, and the cultural company finally lost the lawsuit.

Su Mei recorded the words of the editor-in-chief with a pen, and then asked Wen Xiaowan's boyfriend. His name is Yang Zi, and Wen Xiaowan is a colleague, a book planning editor, who has done a lot of suspense books. After the incident, the police went to his residence to make interrogation records, and found nothing suspicious.

When Yang Zi was questioned, he behaved calmly, his attitude was that this matter had nothing to do with him, and he and Wen Xiaowan had broken up.

Su Mei prompted: You broke up for only a week, and my colleague confirmed that you had a good relationship before, and you had a big fight when you broke up.

Yang Zi tilted his head to the side and said in a flat tone: Lovers break up, isn't it all like this?

Su Mei said: Your eyes are a little red and swollen, you can see that you have cried, and we have investigated and learned that you have given her a silk scarf.

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

Yang Zi told Su Mei that before the breakup, Wen Xiaowan straightened her hair and had an ion perm, and she didn't dare to sleep at night, for fear of crushing her hair

Shape. He knew a trick of putting a gauze towel or silk on the pillow, and when he got up, his hair would not be easy to deform, so he gave her a silk scarf.

Su Mei said: It seems that you have a good relationship, but there is such a paragraph in your web log, let me read it-

Every time I fall in love is the first love, it is impossible to love a person for a lifetime, there are thousands of charming women in the world, beautiful women like clouds, I always have to appreciate different women, feel different love, there is passionate love, there are unforgettable feelings, there is warm attachment, so that a lifetime is not wasted. Moldy vegetables and meat are delicious, why should I eat one dish for a lifetime.

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

Su Mei said: You wrote it in the diary, you deliberately angered her, right?

Yang Zi raised his voice and said: I annoy her, Xiaowan, this woman is too jealous, she is jealous every day, she has an awkward relationship with me when I look at beautiful photos, and I have to check my mobile phone text messages, I am not allowed to do this, I am not allowed to do that, I am annoyed, so I simply broke up.

There was no progress in the investigation of Officers Tu Long and Zhou, and the property management department of the building set up several working groups: the security group, the maintenance team, the sanitation team, and the water and electricity team. At the time of the elevator murder, each team in the building had several night duty officers. There were originally two officers on duty in the elevator monitoring room, but on the night of the incident, the only elevator in operation was not monitored, so the two officers on duty asked for leave and left. Two security guards from the security team did not find anything unusual during their night patrols.

Officers Tu Long and Officer Zhou questioned each other one by one, and asked the officers on duty to write down what they were doing at the time of the crime and their relationship with the victim.

Wen Xiaowan looks average, but she has a hot body, she dresses very fashionably, and her flowing hair looks very charming from behind. The autopsy revealed that she had not been sexually assaulted, and that no one on duty at night knew her, and only a few people had some impression of her.

Bao first conducted a careful survey of the elevator machine room, there are traction wheels and guide wheels in the elevator machine room, and no traces of steel wire suspension were found on the base. Disappointed, Bao Chop inspected the bottom of the elevator shaft, hoping to find a murder weapon such as a wire rope, but found nothing but garbage.

When Bao Chop was about to give up, a suspension point was found on the guide rail support at the top of the elevator shaft, the friction marks were very new, and the anti-rust paint had peeled off.

However, Bao Chu has new doubts: where did the murderer enter the elevator shaft?

There are only two places:

1. The elevator machine room can be opened with a triangular key, and the personnel on duty have this key.

2. In the elevator, open the trapdoor on the top of the car, and the murderer climbs to the top of the car, or he can tie the wire to the guide rail support.

Although no tools for killing people such as wire ropes were found, Bao Slash found something strange in the trash.

Bao Chu said: I checked the trash cans at the elevator entrances on the 42nd, 41st, and 40th floors, hoping to find the tools of the crime that the murderer threw away. I found a strange thing in the trash can, which we see a lot, but now it looks weird.

The dragon said impatiently: What is it? In the future, you will directly say, I annoy you the most.

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

Bao Shu took out a bag of evidence and said: A strange banana, the banana is still wrapped in duct tape, and the inside is hollow.

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

Bao Chu said: The garbage bin on the 41st floor looks like it hasn't been cleaned for at least two days.

Inside the transparent evidence bag was a banana, with a complete peel and a hollow interior, and strangely enough tape wrapped around it.

Professor Leung looked at it carefully, and he asked everyone: Can anyone tell me what this banana is for?
