According to the procedure, the police sealed off the explosion site and searched for the box parts. The fragments were found through the previous video data and the scene. Three hours later, the technicians made a simulation map of the mercury bomb explosion. The outer shell is a toy box containing wooden three-dimensional puzzles. The core of the bomb is two points, one is the trigger method, and the other is the material.
According to the debris at the scene, it is preliminarily judged that this box has a remote control and balanced dual trigger mode. The materials used are homemade tube mines plus standard explosives, a cheap circuit board, a battery, and a flip phone. This bomb is not difficult for EOD personnel, as long as the circuit is cut off, the bomb can be dismantled. . Generally speaking, it was made by a person with exquisite design, insufficient expertise, and familiarity with explosives.
This preliminary conclusion seems contradictory. The EOD supervisor further explained to the detectives: the exquisite design refers to the use of space in the box, and the design of the mercury organ, all of which indicate that the suspect has strong manual skills. The lack of professional knowledge means that the difficulty of disassembling the bomb is very low. In front of professionals, the beautiful mercury mechanism is just a decoration. The most fatal design flaw of this bomb is that there is no need to select the red and blue lines at all, and the bomb can be dismantled by directly cutting off the battery power cord.
However, the exquisite design makes up for the lack of professionalism to a certain extent. During the on-site operation, the EOD operator was faced with a dilemma. He had to do fine manual operation, hooking up and cutting the bottom line from the explosive gap with a hook, and soon the EOD operator found that the wire had no extra length and no room for hooking up. The only way to do this is to reach in with pliers and cut the wires. There is a certain room for maneuver, but the EOD personnel must face a choice. If the EOD operator wears a bulky explosion-proof suit, it is difficult for him to perform micromanagement, as long as there is a slight shake, the mercury mechanism will be touched. If you don¡¯t wear anti-explosion suits, tremble while holding the armor that exploded, or the EOD personnel operate a lot, both of them have to go to see God. No one in the EOD department has performed micro-operations with such a low error tolerance rate.
The reason why it is said that the suspect is familiar with explosives is because the suspect knows the principle of explosives and the way to trigger them. The EOD department believes that the suspect is a person who has normal contact with explosives, but has no normal contact with bombs on a daily basis. In terms of the strength of the EOD department, the bombs they made themselves are basically indestructible. Since more than ten years ago, countries such as the United States have given priority to detonation in dealing with explosives, sending the bomb to a safe place and detonating it. EOD personnel are not encouraged to dismantle bombs on site, unless hostages are involved. security or other reasons.
The EOD director introduced: "Single circuit, no trap, just like connecting a wire directly from the power supply to the light bulb, as long as the wire is cut, the light bulb will definitely not light up. We don't know the other party's intentions, and we can't figure out the other party's thoughts. Double trigger The method shows that he can do better, but the design of the bomb is very simple. We have searched the bombing crime data of the European Union and my country in the past 30 years, and there is no bomb similar to this bomb. Therefore, there is There are reasons to suspect that the suspect is a first-time offender."
There are many classifications in the criminal investigation department, including arson, poisoning, theft, murder and other classification departments. When an important case occurs, the frontline police department will dispatch the case according to the specific conditions of the three major criminal investigation areas, not limited to the division of jurisdiction. Among the three major criminal investigation districts in London, the Southern District Criminal Investigation Department often deals with gang crimes and kidnapping cases. The North District Criminal Investigation Department has more experience in investigating chemical crimes such as arson and poisoning. The Criminal Investigation Department of the Central District is responsible for serial murders and bombings.
The person in charge of this case is a woman named Betty, about 30 years old, and she is the team leader of the special case group of the Criminal Investigation Department of the Central District. Her short hairsprayed hair gives her a very sophisticated look. Betty walked up to the projection cloth: "Hi everyone, I'm Betty. First of all, let me introduce the participation in this meeting, and it's the first time I've heard of the civilian who participated in the case meeting, Mr. Liang Xiliang."
Everyone looked over, Liang Xi raised his hand and forced a smile.
Betty said: "Mr. Liang is a detective. Mr. Detective brought us a map, which he claimed was given to him by the suspect. Look at the screen, it is a paper administrative map of Greater London that was officially released half a year ago. We went to the city hall to get a copy of the same map for scanning and comparison, and found no difference as Mr. Detective said. Except for the three numbers 27, 13 and 35 on it. Mr. Detective thought it was 13:35 on the 27th. Today It's the 30th, and according to Mr. Detective's theory, there will be a new bombing on the 27th of next month."
Liang Xi interjected: "Sorry, I mean the three numbers are 13:35 on the 27th, and I didn't say anything would happen."
Betty glanced at Liang Xi, ignored him and said, "In short, we have scanned and compared many times and found no difference between the two maps. Although the case happened in the Southern District, Mr. Downer handed over the case to The Central District is in charge. The brothers and Mr. Detective in the Southern District have had a hard day, and we will be in charge of the rest of the matter in the Central District. Two, your work is over. Thank you."
Baker glanced at Liang Xi and stood up, Liang Xi asked: "Since the map and the case are notWarehouse management, warehouse management confirmed that there are such rumors, and he himself thinks there may be problems. When answering Liang Xi's phone call, Betty and the team members were comprehensively analyzing the information of all members of the EOD department and determining the order of interviews.
Soon Betty arrived at the scene of the explosion, and after understanding the situation, she found that all the victims were staff members of the Binghai Building Law Firm. Betty couldn't understand, it's impossible, her own people scanned the map several times, but didn't find any difference, Liang Xi didn't have a map but could scan the difference?
A team member reminded: "It is said that Liang Xi has some background as a magician."
This hint was very direct, and Betty asked back: "He directed and acted by himself?"
Team member: "Otherwise, how do you explain his prophecy?"
Betty thought for a while: "See how he explains this problem."
Liang Xi received a call from Betty and replied: "I'm picking up my girlfriend from get off work, and I'm not free now." He already knew about a bombing in a certain restaurant.
Betty said: "Mr. Liang, three people died."
Liang Xi replied: "I know, I'm not free now, I'll talk about it tomorrow if I have something to do."
Betty said: "Mr. Liang, I am very polite to invite you to the police station. If you refuse, we will have to send someone to pick you up. It will be difficult for everyone."
"Send someone to pick me up." Silly, Liang Xi called: "Sprinkle money, borrow a lawyer."
Bobby: "Anything fun?"
Liang Xi: "Yes, it's fun. I'm going to be arrested soon, and I can't explain it." You can't betray Fiona, right? While Fiona was an official hacker, hacking into the Central Technology Department's computers was at least a violation. This is not why Liang Xi doesn't want to explain. As I said before, the best way to deal with long-term premeditated crimes is to disrupt the opponent's plan. Since the suspect involved himself in the matter, he would go to live in the police station for a few days to break the suspect's original plan.
As a detective, Liang Xi already knew the possibility that Betty suspected him and then detained him. Liang Xi knew the direction of the matter as soon as he turned his head. Liang Xi didn't mean to argue with Betty, he would not let himself be uneducated because of other people's impoliteness. Fighting against Betty, it seems that he is too small.
Considering the case itself, is this the last case? Impossible, once the case involves a law firm, the data will become very large. The first thing to do is to determine which lawyer the suspect targeted, and then to figure out whether the lawyer was attacked for professional or personal reasons. What made Liang Xi uneasy was that the suspects were not good men and women. The homeless man would kill him if he wanted to, and he didn't care. It might be because he didn't treat the homeless man as a normal person. Where's the lawyer? 3 dead and 5 injured, doesn't he care about killing innocent people by mistake?
While talking, Karin came out of the hospital, Liang Xi greeted her, hugged and kissed to explain the situation. The two sat down in the small park of the hospital, leaned together and had a little whisper. About ten minutes later, two plainclothes came to the door and showed their IDs: "Liang Xi, please come with us." Judicial arrest requires a reason, but not evidence. The arrest time limit is 24 hours. If the case is complicated, you can apply for an extension of the detention time. .
Liang Xi went quickly, and Karin took Liang Xi's car keys and shouted: "Honey, if you have nothing to do, stay a few more days, I like the heating in your apartment."
Liang Xi looked back and glared, and Karin blew a kiss: "I miss you." Karin had no idea about Liang Xi's detention, and the situation was under Liang Xi's prediction and control.
In order to be successfully detained, Liang Xi didn't know anything about Betty's questions, and only answered one sentence: "Talk to my lawyer if you have anything to do."
According to Liang Xi's request, the Clement Group finally found a stupid lawyer. With the help of the stupid lawyer, Liang Xi was successfully detained by the Criminal Investigation Department of the Central District in the criminal investigation department's suspect detention room. An hour later, according to Liang Xi's arrangement, the reporter contacted by Karin called the Criminal Investigation Department and confirmed that the short-lived Internet celebrity Liang Xi was detained by the Central District Criminal Investigation Department as a suspect. Liang Xi didn't want his resources to put pressure on Betty, in fact, these resources were very smart, and they would not take care of Liang Xi's affairs unless Liang Xi asked. The purpose of Liang Xi is to tell the suspect through the Internet: I have been arrested, and I can¡¯t get out for a few days, you can play your game yourself.
