The paper "On the Characteristics of Theft Cases and Countermeasures for Digging Deep into Crimes" is about 5000 words. Ok, four questions!

With the development of economy and the increase of means of transportation, motor vehicle theft cases are increasingly prominent in a series of property infringement cases. It has become a cancer that infringes on citizens' property. Therefore, it has become an important task to strengthen the investigation of motor vehicle theft cases and crack down on motor vehicle theft crimes. ?

First, the status quo and causes of motor vehicle theft cases

In 2005, China public security organs filed 683,000 cases of motor vehicle theft, up 2.9 percentage points year-on-year. In recent years, the number of motor vehicle theft cases has gradually increased. Motor vehicle theft cases are generally a series of cases, involving a huge amount of money, a large number of people involved and a wide span, causing great economic losses to the people, with a bad nature and serious impact. On April 16, 2007, Shenzhen Interpol Detachment, with the strong support of the Municipal Bureau's Action Technology Detachment and close cooperation with Longgang Branch, made a decisive attack, successfully cracked the Liao car theft gang case (code-named "September 09" case), knocked out a criminal gang that had been madly stealing cars for a long time in Longgang District of this city and many cities and counties in the province, arrested 4 suspects of car theft, and seized 4 stolen cars and 4 tools for committing crimes. ?

Objectively speaking, there are the following reasons for the frequent occurrence of motor vehicle theft cases:

1, the number of motor vehicles has increased dramatically. With the rapid development of social economy, people's living standards have been continuously improved, and people's purchasing power has been significantly enhanced. A large number of motor vehicles objectively provide targets for criminal suspects. ?

2, motor vehicle parking management confusion. 90% of the motor vehicles stolen from June 5438 to May 2007 in Heshan City were parked on unattended roadsides, residential areas and open spaces. ?

3. Motor vehicle owners are backward in anti-theft awareness. A considerable number of car owners, especially used car owners, think that car thieves do not have such courage, so their awareness of vehicle theft is poor. At night, the vehicles are parked around, and few cars have anti-theft devices. Locking the car only depends on the lock on the door, which provides convenient conditions for the car theft suspect to commit crimes. ?

4. The anti-theft method for motor vehicles is simple. Among the stolen cars, some vehicles used electronic alarm devices. Because the electronic anti-theft lock has been put on the market for a long time, the anti-theft technology level of this product has not improved in recent years, and the car thief knows the structure and disassembly method of this electronic lock like the palm of his hand, so the car using this electronic lock has been stolen frequently. ?

In addition, it is easy to sell stolen goods in motor vehicle theft cases subjectively, which is the reason for its frequent occurrence; Failure to crack down on motor vehicle theft cases is another important factor in the high incidence of such cases. ?

Second, the characteristics of motor vehicle theft cases?

Compared with general theft cases, motor vehicle theft cases have the following characteristics:

(1) There are many premeditated activities, and the crime time is short, so it is quick to escape from the scene. Most criminals who steal motor vehicles know the internal structure of motor vehicles, and there are premeditated processes before committing crimes, such as preparing crime tools, determining the direction of escape, choosing the place to hide stolen goods, looking for buyers, sneaking into the crime area, looking for crime targets, and waiting for opportunities to commit crimes. Because the perpetrator has prepared special crime tools and mastered the skills of unlocking and stealing cars, once the target is selected, the unlocking and ignition procedures of a car can be completed within a few minutes, and the car can be stolen and fled from the scene. At the scene, in general, except for the traces of car tires parked on the ground, other traces are rarely found, which brings certain difficulties to the on-site investigators in collecting traces and obtaining evidence. ?

(2) The gang committed crimes. Criminals who steal motor vehicles rarely commit crimes alone, usually by gangs, in order to successfully sell stolen goods and avoid investigation and punishment. There is a clear division of labor among gang members, some specialize in stepping on the spot, some specialize in unlocking cars, and some specialize in selling stolen goods. Basically form a criminal gang that steals, hides, transports, refits and sells stolen goods. ?

(three) continuous crime, criminal tactics are habitual. Most criminals who steal motor vehicles commit crimes continuously and wander in a certain range. After the success of the first crime, criminals are often tempted by high profits and often commit crimes many times. At the same time, in order to escape the blow, car thieves usually jump around in their familiar areas to commit crimes. Traces and physical evidence left on stolen vehicles can often reflect professional characteristics, technical level and means of committing crimes. ?

(4) There are stolen cars to be investigated. From the perspective of investigation, the most favorable condition for motor vehicle theft is that there are stolen cars to be investigated. The model, car number and engine number of each motor vehicle are specific. No matter what kind of car the criminal steals, the stolen car closely connects him with the criminal case, forming clues and evidence for investigators to search. Criminals are bound to sell stolen cars after stealing them, while people who buy stolen cars have to drive on the road after buying them, which provides favorable conditions for detecting car theft cases. In addition, China has a strict management system for the purchase and use of motor vehicles, and stolen vehicles may be found at any time in many links such as settlement procedures, license plates, annual inspection, driving, repair and parking. ?

(5) Party A commits a crime, and Party B commits the crime of selling stolen goods and escaping. In order to escape the blow, criminals who steal motor vehicles generally do not sell stolen goods at the scene of the crime, but quickly flee the scene after committing the crime and sell stolen goods in different places, which is very fast. Some contact buyers in different places before committing crimes, understand the types of motor vehicles that buyers need, negotiate the price, and then steal the vehicles; Some quickly fled the crime scene after committing crimes, and then modified or repainted the stolen vehicles, and replaced the license plates and car purchase certificates to sell stolen goods in different places. In the case of Liao's car theft detected by our city, members of the gang, together with fellow villagers, fled the province to commit crimes. A place was hit hard, so I went to B place, and the chosen places of residence were rented houses with complicated personnel conditions. Even if they commit crimes in the same city, they frequently change their residence. ?

(6) Judging from the time and place of motor vehicle theft, most of the theft places are remote places with dim light and few pedestrians, and the vehicles parked in these places can easily become the prey of thieves; Theft time is mostly around 4 am, so people are sleepy and not easy to wake up. At this time, the security personnel patrolling are also sleepy, their vigilance is reduced, and their prevention work is relatively weak. ?

Third, the investigation essentials of motor vehicle theft cases?

The investigation of motor vehicle theft cases should be carried out at different levels from the following aspects. ?

(a) accept the report and make a good registration. The time and place of motor vehicle theft cases are generally very clear. When accepting the report, you should ask the owner in detail, record it truthfully and register it well. The contents of registration include: the names, work units and addresses of the informant and the owner, the time, place and process when the case occurred or was discovered, the type, brand, model, color, age, engine and frame number of the stolen vehicle, the memory, repair and replacement of accessories, door locks and keys, and the activities of vehicles and people parked around when parking. ?

(2) Establish a rapid response mechanism and strengthen pursuit and interception. In view of the characteristics of motor vehicle theft, such as quick crime, quick escape and quick sale of stolen goods, the policy of "quick response" is adopted and a quick response mechanism is established. Once receiving the alarm mechanism, we should immediately inform the public security organs of the route to which the perpetrators may flee for interception, and at the same time organize forces to pursue them along the direction in which the perpetrators may flee. In the pursuit, we should make full use of the video monitoring system of the expressway toll station to determine the escape direction of the criminals and capture the suspects through the pursuit. ?

(3) Strictly control the motor vehicle maintenance industry. After the criminal suspects stole motor vehicles, a considerable part of them were transported and sold after being modified by motor vehicle repair shops. Therefore, it is necessary to strengthen the post control of special industries such as motor vehicle maintenance points. It is necessary to severely investigate and punish the owners and related personnel who find that criminals have changed the engine number and frame number, changed the body and color, or modified stolen cars and bought and sold stolen auto parts. All those who should be banned should be banned, and all those who should be investigated for criminal responsibility should be investigated for criminal responsibility, and they will never be soft. Criminal investigation departments should attach importance to the control of special information and intelligence of construction positions in motor vehicle repair shops and other related industries, especially to strengthen the use of special information of high-quality projects, keep abreast of the dynamics and whereabouts of criminal suspects in time, and strive to take the initiative to catch them all. ?

(four) to strengthen road inspection and interception, found stolen vehicles. In view of the characteristics of criminal suspects stealing cars in place A, selling stolen goods in place B, and fugitives running away secretly, the criminal investigation department should set up necessary checkpoints in the traffic arteries within its jurisdiction and the traffic arteries bordering neighboring counties, especially the highway trunk lines entering and leaving the provincial boundaries and key areas to intercept stolen cars and criminal suspects; Highway patrol and criminal police should cooperate closely, carry out road inspection in a timely manner, and strictly examine vehicles with inconsistent vehicle photos, altered or destroyed engines, and find suspicious vehicles from them. In road inspection and interception, we should make full use of the online inquiry information system of stolen vehicles to find stolen vehicles. ?

(five) to strengthen the investigation and expand the results. In view of the fact that most cases of car theft are committed by gangs and continue to commit crimes, we must never link cases together when investigating such cases. It is necessary to pay attention to collecting information about car theft in other places, strengthen the interrogation of suspects who have been arrested for stealing motor vehicles, and inform relevant regions of their criminal characteristics, strengthen cooperation, string together cases with the same modus operandi in relevant regions, and investigate them together, so as to try to break one case and catch one person and dig a group. ?

(6) Establish and improve motor vehicle files. The criminal investigation department shall, together with the traffic police, internal security and other administrative departments, do a good job in the investigation of the owners of all units, and focus on verification after finding suspicious vehicles by looking at the vehicle files. It is necessary to establish and improve the motor vehicle text, photos, pictures and data files, implement computer management and retrieval of motor vehicle data, and network with computers in the whole province and the whole country, give full play to the role of computer network system in investigating stolen cars, and ensure smooth information and enjoyment of information. Generally speaking, stolen vehicles are mostly unlicensed vehicles or vehicles with fake license plates. Putting an end to such vehicles will block the flow of stolen cars to society. Therefore, the traffic police department and the police station should actively strive for the cooperation of grassroots organizations, organize the police in the area of responsibility to investigate the motor vehicles within their jurisdiction, grasp the basic situation of licensed and unlicensed motor vehicles and the owners, and comprehensively and thoroughly rectify unlicensed and unlicensed vehicles. If unlicensed and unlicensed motor vehicles are found, they will be seized resolutely. For motor vehicles of unknown origin, it is necessary to trace the source, trace the source, severely crack down on gangs that steal motor vehicles, and completely eradicate the motor vehicle stolen goods market. ?

(seven) constantly innovate the means of investigation, strengthen the internal professional division of labor, and increase the detection of motor vehicle theft cases. The first is quick response. With the great opening of society, the great mobility of personnel and the great progress of communication and transportation, it is impossible to investigate the case step by step, but only to make a quick decision. After the case happens, we must rush to the scene in time, make decisive decisions according to the case, quickly adjust the police force, chase and stop the stolen goods. Second, fully grasp the characteristics of such cases, identify the breakthrough point, focus on key people, strictly control the channels of selling stolen goods, and constantly realize the transformation from the traditional investigation mode from case to person to case and from things to people. The third is to strengthen technical monitoring and discover case clues in time. It is necessary to make full use of modern science and technology and criminal technical means, give play to the role of "online investigation and control", technical investigation means, highway toll stations and urban "electronic eye" monitoring, obtain relevant information in time, find clues and solve cases in time. ? 「HT5H」

IV. Countermeasures to prevent motor vehicle theft cases?

In view of the high incidence of motor vehicle theft cases, we should adopt a "comprehensive management" approach, focusing on prevention and simultaneously fighting and preventing. ?

(1) Strengthen prevention publicity and education. It is necessary to make full use of newspapers, radio, television and other news media, educate the majority of car owners to raise their awareness of safety precautions, teach them some basic preventive methods and skills, actively install alarm devices and anti-theft locks on motor vehicles, and park their vehicles in garages, indoors or supervised places. The establishment of parking lots in commercial centers and residential areas can implement the responsibility of safety prevention in accordance with the principle of combining responsibility with rights and enhance the ability of prevention. This can not only effectively prevent motor vehicle theft cases, but also prepare for the increasing number of private cars. ?

(2) Strengthen the control of social patrols and adopt waiting tactics in due course. Regularly analyze the characteristics and laws of motor vehicle cases, adjust the police force arrangement in a targeted manner, and actively carry out road patrol, cosmetic tracking, mobile observation, and investigation. Through the comprehensive use of patrol, inspection, first, blocking, blocking, digging and other facilities, improve the ability to control the social surface. In the street inspection, the investigation of suspicious vehicles was particularly strengthened. Units and owners in key areas such as shopping malls, hospitals and residential quarters should strengthen the density and intensity of night patrols, strive to capture the current situation, and often carry out targeted sign-in and waiting. In order to determine the physical characteristics and vehicle use of the suspect in the Liao gang car theft case, the police of the task force decided to wait for tracking downstairs in their residence. People who come down from the upstairs where the suspect lives, especially those who leave by car, will be secretly followed by investigators, and then return to their original places after confirming that the person is not suspected of committing a crime. Finally, after a period of tracking, investigators found that a young man of about 30 years old was suspected of committing a crime by driving a Jetta with a Guangdong BT3263 license plate. After picking up two people on the road, the man parked his car near the shopping mall from time to time. Two of them got off the bus, one followed the people who entered the mall, and the other unlocked the door with a tool in a black briefcase. Due to various reasons, the suspect did not succeed, but our investigators have clearly grasped the physical characteristics, vehicle use and activity rules of the suspect, and achieved good results in investigation and tracking. ? 「JP」

(three) timely organize special actions to combat motor vehicle theft. After criminals steal motor vehicles, many of them are sold to other places or rural areas, and they are basically not used for their own use. Therefore, to solve motor vehicle theft cases, we must break the geographical boundaries, strengthen the information exchange between various departments of our unit, strengthen communication and coordination with foreign public security organs, and exchange information. The criminal investigation department timely organized the detection of the battle, and the police station fully mobilized the masses to provide clues to the crime of motor vehicle theft. Those who are verified to be true should be rewarded in time, and strive to crack a number of cases, arrest a number of criminals, recover a number of stolen cars, and severely crack down on the arrogance of criminals who steal motor vehicles. ?

(4) Introduce the anti-theft skills and experience of vehicles to drivers through various channels, and remind owners to take necessary measures to strengthen the anti-theft work of vehicles. For example, in order to prevent the vehicle from being stolen, some car owners installed an oil circuit power switch in the hidden place of the car. When people leave the car, turn off the oil circuit power supply. When the car is started illegally, the engine cannot be started because the oil supply circuit is cut off, which prevents the car from being stolen. This method is simple and easy, and because the switch is installed in different positions of each car, even if the car thief realizes that there is a fuel supply circuit switch in the car, it is not easy to find it in a short time, and finally he can only give up stealing the car. In handling the case, we have repeatedly found that the car is equipped with such a small switch, forcing the suspect to finally give up stealing the car. In addition, when the driver leaves the vehicle, he turns on the radio and turns up the volume. Generally, a car thief only pays attention to trying to disarm the alarm when committing a crime, but at the moment when the power is turned on, the sound of the radio will frighten him into panic and will also play a certain alarm role. Another method is that when the owner is ready to stop for a long time, he will switch the ignition wires of each cylinder, so that the car thief can't start the vehicle smoothly, and it is also helpful for the vehicle to prevent theft. In short, the relevant departments can introduce some of the above-mentioned effective anti-theft methods to the masses, so as to improve the anti-theft coefficient of vehicles. ?

(5) Strengthen the construction and management of parking lots. With the increasing number of motor vehicles, it is imperative to choose a suitable location to build a regular parking lot. Especially in some residential quarters under construction, parking lot construction should be taken as a compulsory measure and implemented by developers to avoid no parking space after the completion of residential quarters. At the same time, it is necessary to manage the temporary parking lots in roadside and open residential areas, and be guarded by specialized personnel 24 hours a day, and collect parking fees according to the parking lot management measures. At the same time, it is necessary to vigorously advocate and popularize the installation of probes in parking lots, strengthen the monitoring scope, and not give thieves an opportunity. ?

(six) give play to the advantages of science and technology, improve the technical content of vehicle anti-theft. Public security organs can cooperate with technology development companies to develop vehicle anti-theft products in view of the defects and deficiencies in vehicle anti-theft For example, with the application of GPS positioning system, the owner can not only know the orientation of the vehicle at any time, but also remotely control the flameout of the vehicle. Another example is the vehicle VIN code that is currently being promoted. The label of this code can be added from the big frame and engine of the vehicle to some parts that can be reused after being removed by car thieves, such as the front and rear windshields and doors of the vehicle. While preventing vehicles from being stolen, it also helps to crack down on criminal activities of stealing motor vehicles. ?

Conclusion?

The research on motor vehicle theft cases has been paid more and more attention in theory and matured in practice. The Ministry of Public Security, the Supreme Law and the Supreme People's Procuratorate have issued some policies and documents on the detection, handling and legal application of motor vehicle theft cases. In practice, public security organs in many places also regard the detection of motor vehicle theft cases as an aspect of investigation. These also reflect the great influence of motor vehicle theft cases in social life from one angle. Therefore, investigators should further strengthen the awareness of combining fighting with prevention and comprehensive management, strengthen patrol and increase publicity and prevention; The combination of ordinary investigation means and high-tech means will strengthen the awareness of series of cases and the intensity of investigation, so as to pay equal attention to the crackdown and prevention of motor vehicle theft cases and create a harmonious and stable living space for the people.
