There have been many horrific murders in the university: teacher Zhao Limeng hummed a song and cut off the heads of two students in the boys' dormitory; lecturer Tan Xuan killed a girl due to a relationship dispute between teacher and student, and pressed thumbtacks all over the girl's face; Central China
Dozens of students from a regional university beat a thief to death and then burned his body; two students from a university in the Pearl River Delta had a dispute over an online game; one student tricked another student into licking a mouthful of sulfuric acid...
At 8 o'clock in the morning on November 20, 2008, a bizarre and horrific bombing and murder occurred at a northern polytechnic university: a fat teacher was killed in the toilet. She was the school counselor. The death scene was horrific: the lower body of the female counselor
It was blown away, the leather skirt was torn into strips, blood spurted onto the wall, and pieces of human tissue were scattered everywhere. The toes of the deceased were at least four meters away from the nose.
At that time, a girl went to have breakfast. She passed by the toilet window with her lunch box, and a small piece of human tissue fell into the lunch box.
From the curly hair and wrinkles, you can tell which part of the human body the piece of meat comes from. The girl was so disgusted that she couldn't eat for a whole day. She said to her classmates: It's miserable, it's so miserable, there was a loud bang, and it exploded.
My pubic hair is flying around.
The school and the police immediately blocked the news and prohibited all teachers and students from talking about the incident. Various gossips were circulated among the students. The most common version was: a female teacher was raped and murdered, and her intestines were taken out by the murderer.
A grenade was also inserted into the lower body of the deceased and then detonated.
After the explosion and murder, fear permeated the campus. For a time, the price of rental housing near the school rose sharply. Many students were unwilling to stay on campus due to panic and chose to live off campus.
After the police investigated the scene, explosion prevention experts believed that the murderer had a very high IQ and extremely professional bomb-making skills.
The murderer used a sanitary napkin bomb!
The bomb was cleverly hidden in the sanitary napkin of the deceased. While investigating the method used by the murderer to detonate the bomb, the police reported the case to the highest public security agency and requested the dispatch of a special case team to assist in the investigation of the explosion.
Bao Zhan looked at the criminal investigation file and asked Su Mei for a sanitary napkin in embarrassment. Su Mei stared at her eyes and muttered something perverted, then took out a pad and threw it on the table. Bao Zhan studied for a long time and couldn't figure it out.
How could they hide the bomb? Su Mei took out another thickened sanitary napkin to prevent side leakage and asked them to study it. Hua Long smiled and said: We old men really don’t understand this kind of thing about women, but...
I do know a kind of explosive: plastic explosive.
Plastic explosive, referred to as C4, its main component is polyisobutylene, which is made of gunpowder mixed with plastic. It is extremely powerful. This is a highly efficient explosive, consisting of trinitrotoluene, semtex (semtex plastic explosive) and white phosphorus
It is mixed with other high-performance explosive substances, can be ground into powder, can be installed in rubber materials at will, and then extruded into any shape. It can be placed in very hidden places and stick to it as firmly as chewing gum.
Bai Jingyu said: C4 plastic explosive can easily evade X-ray security inspections, which is why terrorists like to use it. Some international agents have chewing gum bombs in their toolboxes. The smallest time bomb in the world can be as big as a soybean.
Small, but can be broken into pieces
personal brain.
Professor Liang added: You know, the kind of bomb disguised as chewing gum used by the agents looks just like real chewing gum. It is a very small and thin piece that can blow open a door or a wall and is hidden in a sanitary napkin.
, enough to blow a person to pieces.
Bai Jingyu: You have the right to choose whether to accept this case or not. I set up the special case team myself, and I don’t want to lose my troops.
Professor Liang: Thank you, I understand what you mean.
The detection process of any major murder case is full of danger. Bao Zhan, Hua Long and Su Mei did not understand why Bai Jingyu was so worried about the explosion. Bai Jingyu coughed and talked about a past incident about Professor Liang. Professor Liang used to
Many notorious criminals have been captured. One of the criminals escaped from prison and killed one of Professor Liang's police colleagues. Professor Liang rushed to the scene and turned over the body of his colleague, when the criminal used his mobile phone to detonate the bomb hidden in the body.
Professor Liang survived the catastrophe, but he will spend the rest of his life in a wheelchair...
Professor Liang interrupted Bai Jingyu's words and said lightly: Let's go!
The police chief and the vice-principal received the special case team. Police officers with police dogs could be seen everywhere on campus, and several police officers with detection equipment were looking for something on the grass of the football field.
The vice-president is a woman in her fifties. She said that this polytechnic university has a long history and has tens of thousands of teachers and students. The development of national defense science and technology is the school’s mission. Over the years, many talents have emerged, and among its alumni there are not only political leaders.
, as well as nuclear bomb designers and scientists and academicians in cutting-edge science and technology fields. The school undertakes more than a thousand scientific research projects every year, and there are more than a dozen national-level laboratories.
Professor Liang said: Approximately how many people in this university know how to make bombs?
The vice president said: Students from many majors can make bombs, such as ammunition engineering and explosive technology, weapon systems and launch engineering, aerospace science and technology, aircraft design and engineering, materials physics and chemistry, special energy engineering and pyrotechnics technology
.It is not difficult for these professional teachers and students to make a bomb.
Bao Zhan: Both bombings and arson cases have a characteristic. The murderer likes to commit crimes serially.
The vice-principal asked in horror: You mean, there will be another explosion?
Bao Zhan said: It's very possible.
Professor Liang: We must find the murderer before the next bomb explodes.
Bao Zhan: In the next explosion, several people may be killed, or... a teaching building or dormitory building may be destroyed.
The vice-principal said: Oh my God, are you kidding me? On behalf of the school, I implore your special case team to catch this murderer quickly! We are willing to provide all conveniences, including my car for you to use, and you can also drive at the five-star hotel near the school.
A first-class hotel has reserved a presidential suite for you to work in.
Professor Liang: I have already chosen an office location.
The police chief asked: Where?
Professor Liang pointed to the football field where they were sitting. It was very large and the grass was withered and yellow. It could be seen from the teaching buildings and dormitory buildings on campus, and you could have a panoramic view from a high place. Professor Liang asked the person in charge of the police to
Several tents were set up on the court to serve as temporary offices for the special case team. The person in charge of the police worriedly said that the deceased’s social relationship was simple and there was no initial investigation.
The suspect has been found and in-depth investigation is underway. If the murderer is not simply committing revenge, then he may be seeking revenge on the school or society. The murderer is likely to shift his target to the police and create an even greater terrorist incident.
Hualong said: In the eyes of terrorists, the police are a suitable victim role.
Bao Zhan said: It is not easy to catch this murderer. We are looking for him, and he will also be watching us secretly.
Professor Liang: Yes, we need to let this murderer slowly walk from the dark into the light and into our sight.
The tent was quickly set up on the football field. Professor Liang asked the police chief to prepare explosion-proof blankets, explosive disposal suits, and Dragon Walker bomb disposal robots. There was no cordon around the tent, but electronic monitoring equipment was installed.
Monitor all suspicious persons trying to approach around the clock.
Professor Liang told Hua Long, Su Mei and Bao Zhan that the campus is full of dangers and bombs may be placed in any corner. The special case team should not act like heroes, do not go out of the tent to act alone, and do not touch anything in the school.
The special case team must first ensure their own life safety before they can solve the case.
Professor Liang's passive detection methods made everyone feel pressured.
Bao Zhan thought that Professor Liang, who was resourceful and thoughtful, had almost been killed in a bombing before. This shows how difficult the bombing case is.
Professor Liang asked everyone to relax and not be so nervous. He found a relaxing topic and talked about college life.
Hua Long looked at the campus in front of him and said: My college life was a piece of shit and I can’t bear to look back.
Su Mei said: Ah, in my sad college days, I also had straight bangs, wore a white skirt, and walked along the campus tree-lined avenue with books in my arms. Now that I think about it, why am I so sad?
Professor Liang: What about you, Xiaobao?
Bao Zhan looked at a dormitory building in a daze, suddenly turned his gaze, and said in a low voice: There is someone there looking at us with a telescope.
Everyone pretended to be nonchalant and quietly observed with the corners of their eyes. Sure enough, there was someone on the opposite dormitory building looking over with a telescope. Professor Liang rolled his wheelchair, walked to a position where the telescope could not see, and called to inform him of bomb disposal.
The team immediately prepared. After a while, a bomb disposal expert ran into the tent panting.
Professor Liang: Is the bomb squad here?
Bomb disposal expert: I am.
Professor Liang: Just you?
Bomb disposal expert: Everyone else has taken leave. The murderer has plunged the school into panic, including my colleagues. In fact, I am an explosion prevention expert, not even an expert. I am the leader of the explosion prevention team.
Hualong: Is there any difference?
Bomb disposal expert: The difference is huge, I haven’t even defused a bomb.
Bao Zhan: Explosions and murders are rare. This time, you can come in handy.
The police secretly arrested the peeping boy. Bomb disposal experts then carefully inspected the boy's dormitory. No explosives were found, but they found a sanitary napkin that was about to burn to ashes in the trash can, and the underwear he had changed from.
There is also a sanitary napkin stuck on it, and there are some unused sanitary napkins in his drawer.
Obviously, this is a boy with a quirk, a boy who often wears sanitary napkins.
