Shenzhen Luohu murder case sounds alarm bell home security awareness needs to be enhanced
At 6 o'clock in the morning on April 15th, a tragedy occurred in the urban famous garden district of Luohu District, Shenzhen City, Guangdong Province: three female white-collar workers who had rented a house together were slashed and killed by a man inside the house. The murderer ignited and burned the scene. The smoke was discovered by the security guard. One woman was rescued after the incident and the other two women were killed.
According to the police, before the incident, the suspect Xie Mou went online in the Internet cafe downstairs. In the middle of the night, he climbed the 6th floor platform along the fire exit to find the target of theft. After searching for the platform on the 6th floor, he suddenly found a window on the 7th floor. Off, then sneak into the room. This house happens to be the 7th floor B room of Building A, where 3 girls live. The tragedy also occurs when the dream wakes up. According to reports, the three women on the scene are employees of China Resources Group. The two women killed are all famous schools, and all of them are 85 years old. They are still under 30 years old. They are also very popular at work. They have ideals, pursuits and futures. However, it was awkward to die because of this accident. In this case, although a woman was rescued, the woman also suffered more than 20 knives and was seriously injured and admitted to the hospital.
At present, the case has been broken, and the suspect has fallen into the French Open, but it has sounded the alarm for people with weak security awareness, and has made security industry practitioners committed to launching safer and more complete solutions .
Community management vulnerability
In fact, all entrances to the urban famous garden community must be swiped in order to enter. Foreigners who want to enter the relatives and friends must also register their ID cards. The reporters of Nandu tried to enter the community in the name of visiting friends at noon yesterday, but they were rejected because they did not bring their ID cards. The reporter tried to drive into the underground garage of the community and was also blocked. The signboard showed that the garage was not open to the public.
However, the security in the community is not tight, the reporter did not pay attention to the garage security, walked directly to the garage on the first floor, and was prompted to swipe when trying to enter the elevator. A closed fire exit was found on the left hand side of the first floor. Push your hand open and you will be able to go straight to the 6th floor.
There are no exits in the middle of the five-story staircase, which is dark and damp, and there is a pool of water on the ground. When I walked to the 6th floor, the door and lights suddenly appeared. The reporter walked out and saw that he had reached the door of the elevator on the 6th floor. It is already an internal area, and no need to swipe the card up and down the elevator.
In addition, the windows on the 6th floor and above of the building are no longer equipped with security windows. This also allows the suspects to have the opportunity to climb into the houses of the three women’s rented houses from the unopened windows. And killing people arson.
In this case, the poor management of community access control is one of the main reasons for the tragedy. The main reason for the suspects being able to enter the office is the loopholes in the management of the community and the weak security awareness of the people. They broke through the three levels of the access control of the community, the access control of the A building and the window of the B room (the crime scene) on the 7th floor.
Inadequate technical defense needs to be repaired by civil air defense
It is understood that the access control facilities such as the urban famous garden are relatively complete. According to Wang Dapeng, general manager of Kaierui Technology (Shenzhen) Co., Ltd., the access control products selected by many communities in engineering construction are relatively cheap. Most of the quality is not particularly good. It is a large iron gate, as long as there is a person swiping the card. The person behind can follow in, or if someone swipes out, the outsider can also take the opportunity to enter the door. This is a loophole in itself. If you use the gate, you can control the flow of people. If you brush the card, you can only let one person Passing, together with the security guards at the door security room, can prevent outsiders from using the community access control loops into the community. Considering the passage of baby strollers, you can open a special passage next to the access control.
Another major hazard of the access control system is the copy card. At present, the access cards used in many communities are all duplicate cards. Such cards are easy to copy and cannot display user information, which is inconvenient to manage, and it is easy for outsiders to obtain access cards by abnormal means. Wang Dapeng said that from the current situation, the security factor of identity cards is relatively high and easy to manage.
Fire escapes into safety hazards, fire locks can show their talents
In this case, the second level of the criminal suspect’s breakthrough was that the case was found in the building. The fire exit of the building was used because of the lack of use and long-term unattended, creating opportunities for criminal suspects to enter the room.
The fire exit is an emergency passage for the residents to safely reach the downstairs when the common passage cannot pass, and it is also convenient for the relevant personnel to go upstairs for rescue in an emergency. However, the fire exit is also faced with a dilemma: on the one hand, in order to facilitate rescue, the fire passage must be easily opened; on the other hand, in order to prevent the fire passage from becoming a criminal channel for criminals, it must also play a role in theft prevention. The application of the fire lock allows the fire exit to have two choices: install a fire lock at the entrance of the fire exit. When an emergency occurs in the building, in the event of a fire, everyone can escape from the fire exit to the entrance and exit. People can easily open the fire lock from inside and escape the danger; in the case of theft prevention, the residents in the building can swipe the card into the passage. If the criminals force open the fire lock, they will touch the alarm system and the security personnel will arrive at the first time. on site.
However, according to Wei Hua, manager of Junyi Technology Channel Lock Development Department, the current fire locks are widely used in major shopping malls in China, but there are fewer applications in the community, and only a few high-end residential areas have applications. However, this case will give everyone a more comprehensive and in-depth understanding of the safety of the fire exit in the community. This may open the prelude to the popularization of fire locks in the community fire channel in our country.
Reporter's Note: Home security products should not be absent
In this case, it is easy to find a problem, that is, the crime scene has almost no shadow of security products. First of all, the window magnetic alarm was not installed near the open window of the victim's home, which caused the suspect to find the abnormality in time when the suspect entered the room through the window, and no emergency measures were taken; and the suspect was in the first victim's During the operation of the room and turned to the other two victims' rooms, there was no alarm facility in the living room to alert the other two victims; in the process of the criminal suspect's assault, the victim did not seek help in any way; finally, when When the criminal suspect arsoned at the scene of the crime, the property management department saw that there was a smoke from the window to find the case, and there was no alarm product such as a smoke detector at the scene; but in the whole process, no popularity was seen. The highest level of video surveillance products, so that the public security organs spent 17 hours to arrest the suspects, and seized his whereabouts through the bank card usage records illegally obtained by the suspect from the crime scene, instead of passing The most intuitive video surveillance data.
Xie Zhiping, senior market manager of Shengbo, analyzed the case and thought that if the owner or renter can install the corresponding security products in the house, the outcome is likely to be very different. If there is a window detector or other alarm near the window of the crime scene, the first victim can be prepared for it. The alarm ringtone will also have a deterrent effect on the suspect, even if it cannot scare off the suspect. People or the attention of neighbors and security personnel can also allow victims who first come into contact with suspects to have more time to take emergency measures. The suspect will have to go through the living room from the first victim room to the other two rooms. If there is a video composite alarm device in the living room and is connected to the room owner’s mobile phone or tablet, the two victims who have not yet contacted the suspect will You can find the case in your own room and take action quickly or delay the time or counterattack in a relatively safe room and notify the security guard or the police. When the suspect is arson, if a smoke detector is installed at the scene, the case can be discovered earlier, and the rescuer can rush to the scene in time. Perhaps one more victim can be rescued and the damage and loss can be reduced. lowest. Finally, whether the suspect escapes from the window or escapes from the fire exit or the elevator, the public security organ can extract the characteristics of the suspect from the video surveillance data in the course of the investigation after the event, and solve the case as soon as possible.
Some insiders also said that if the security measures in the community are in place, the criminals will have no chance at all. Xie Zhiping said that the lack of security products in such rented houses in the case is common in Shenzhen and even in Guangdong Province. When he approached the customer, he found that the community used for renting generally did not pay much attention to the configuration of security products. The head of the household did not live in the house, so they were not willing to increase the cost, and the renters were only temporarily renting and not willing. Buy and install security products at your own expense. In fact, in the final analysis, people's security awareness is weak, and they are not aware of the serious consequences of the lack of security products.
