"internet plus Kidnapping" Retrieves Nearly 4,000 Missing Children
In March 2010, the Supreme People’s Court, the Supreme People’s Procuratorate, the Ministry of Public Security and the Ministry of Justice jointly issued the Opinions on Punishing the Crime of Abducting and Trafficking Women and Children according to Law, which stipulates that if a child is reported missing or a woman who has reached the age of 14 but is under the age of 18 is reported missing, the public security organ shall immediately file a criminal case and promptly carry out investigation; If it does not belong to its own jurisdiction, it shall be promptly transferred to the public security organ with jurisdiction.
"The Ministry of Public Security has never said that children can be missing for 24 hours before filing a case." Chen Shiqu said that if parents find their children missing, they should call 110 at the first time, and the police must immediately file a case and carry out investigation according to regulations. The Ministry of Public Security has previously made it clear that in all cases of child trafficking, the public security organs implement the "one long and three guarantees system", that is, the main leaders or competent leaders of the county and urban public security organs serve as the project leaders, and are responsible for the investigation of the case, the search and rescue of the trafficked persons, and the appeasement of the victim’s family.
The reporter learned from the the State Council Inter-Ministerial Joint Conference Office and the Criminal Investigation Bureau of the Ministry of Public Security that the publicity campaign of "Caring for Children and Opposing Trafficking" was held in Beijing. In the three years since the emergency release platform "Reunion" of missing children information of the Ministry of Public Security was launched, a total of 3,978 pieces of missing children’s information were released, and 3,901 missing children were recovered, with a recovery rate of 98%.
According to reports, in order to meet the requirements of the "internet plus abduction" era, the Ministry of Public Security has developed the "Reunion" system, an emergency release platform for missing children’s information, which was officially launched on May 15, 2016. Once the missing information of children is released, the platform can help the public security organs to push the missing information of children to a certain range around the missing place through new media and mobile application terminals in the first time, so that more people can obtain relevant information accurately and provide clues in time to help the public security organs solve the case as soon as possible. At present, many new media and mobile applications have been connected to the platform.
Comprehensive Xinhua all-media headlines, People’s Public Security News, etc.
For many years, the police have been tirelessly pursuing abducted children.
Ten lost faces, gradually blurred in the years … …
Look at AI’s meritorious service.
"Not reconciled, if we can’t find a child, we can’t explain it to our parents. We can’t lose!" On July 3rd, on the 6th floor of the Criminal Investigation Bureau of Sichuan Provincial Public Security Department, a white board in the office of Jiang Xiaoling, director of the Anti-trafficking Department, was filled with names, and they intertwined to form a net.
In the past few years, Sichuan abduction police have been "competing" with a child trafficking case. Wang Mouwen is the key to this case. This 63-year-old man is closely related to 13 cases of child abduction in several cities and counties in Sichuan in 2008, 2009, 2010 and 2014. The reporter learned from the Criminal Investigation Bureau of the Sichuan Provincial Public Security Department that the case was the biggest child abduction case in the process of abduction in Sichuan.
In 2014, Wang Mouwen was arrested. Except for the three children who were abducted in that year, the search for the other 10 children has continued to this day. At present, there are still three children still looking for them.
13
Not One Less
On that whiteboard, the names of four abducted children are lined up in a row, with their date of birth and the time and place where they lost. Below the name, the lines are intertwined, and the clue information is connected in series.
"This is the first group of children we found before." Xiao-ling jiang pointed to the whiteboard and looked tired. She didn’t go to sleep until after 2 am for several days. I just flew back to Chengdu from Shenzhen the day before.
There are too many things, there are still three children who have not been found, and they have to mediate the relationship between the children and the two families. Things didn’t go well. She bluntly said, "I have a good personality, but I still can’t help losing my temper."
This is a search for people that has been going on for five years. Jiang Xiaoling secretly struggled. "I’m not willing. If I can’t find a child, I can’t tell my parents. We can’t lose!"
Three children.
Successfully rescued in the year of abduction.
The suspect was arrested
Time goes back to five years ago.
On the evening of April 26th, 2014, a three-year-old child was abducted from Suining, Sichuan. In the surveillance screen, a man in dark underwear left with his child on a motorcycle. After more than two months of investigation, the police grasped the trace of the suspected man and issued a notice to Quanchuan to collect similar cases with the same modus operandi.
According to local reports: on April 7 of that year, a 3-year-old child from Tongjiang, Bazhong was abducted; On June 25th of that year, a 3-year-old child was abducted in Yilong, Nanchong. The three cases were connected in series, the suspect Wang Mouwen was highlighted, and the general whereabouts of the abducted children were found out.
On the evening of July 30, 2014, the arrest operation began. The police arrested Wang Mouwen in Qu County, Dazhou, and arrested some middlemen associated with Wang Mouwen in Guangdong. Three children abducted in September of that year were also successfully rescued.
The case written by Wang Mouwen is not limited to this. In 2014, the construction of public security monitoring in all parts of Sichuan has matured. Through the comparison of massive video information, the police found that in two cases of children lost in the summer of 2009, Wang Mouwen appeared again. "He is not tall, about 1.6 meters. He drags his children away and leaves by motorcycle." Jiang Xiaoling said.
The same suspect has committed crimes many times in a row, and Wang Mouwen is definitely not simple.
10 children
The suspect confessed that they were taken to Guangdong a few years ago.
As the trial continued, shocking progress appeared — — Wang Mouwen confessed that in addition to the three cases in 2014, he also brought 10 children to Shantou, Guangdong Province in Sichuan for three consecutive years in 2008, 2009 and 2010.
Soon, the case was listed as a case supervised by the Ministry of Public Security. In the view of Jiang Xiaoling, who has been engaged in abduction for many years, the case has undoubtedly become the largest child abduction case in Sichuan.
We must find these 10 children.
"For parents, even if they give everything, if they don’t find someone, then everything is meaningless." Compared with catching the suspect, a long-lasting war for finding people has just begun.
Wang Mouwen is the only breakthrough. But it is not easy to pry his mouth open. Wang Mouwen either refused to provide information about the middleman to the police, or constantly retracted his confession, which brought great difficulties to finding people.
At that time, the police escorted Wang Mouwen to Guangdong and asked him to identify the place where the child was sent. In the process, Wang Mouwen was vague. "It seems that it is, but it seems that it is not. The urban construction has changed too much." After a lap, the police got nothing.
"He is a very cunning man, and it is difficult for you to find out the truth of his words." Jiang Xiaoling introduced that in 2015, Wang Mouwen was finally convicted and sentenced to 15 years in prison for his crimes in 2014 and is still serving his sentence.
"But in any case, there must be hope!" The police did not give up.
deadlock
10 "fuzzy" faces
After many years, it is difficult to find people by changing their faces.
In 2015, the Sichuan police carried out an attack on the case. The police sent a task force to Shantou and other places in Guangdong again to explore the clues left by Wang Mouwen and continue to look for people. However, due to dialect barriers and unfamiliar environment, the work is extremely difficult. In addition to learning the bank transaction information left by Wang Mouwen, I got nothing.
Jiang Xiaoling said that the 10 abducted children involved were all under four years old at the time of the crime, and the youngest was only a 100-day-old baby. Children’s ability to remember stories is poor, and they can hardly remember the case. Moreover, they are in the stage of language learning, and their accents will change in just a few months. The police who participated in the rescue of three abducted children in 2014 said that when they were found in Guangdong, only in the past five months, the children had spoken fluent Chaoshan dialect, and their biological parents’ impressions were blurred.
One road is impassable, so change to another. In 2016, the task force found Professor Zhao Chengwen, an expert in appearance at China Criminal Police College, for help. I hope that through the way of portraits, I can show the appearance of children in their teens, and then look for people according to the portraits.
A group of Sichuanese went to Guangdong again with portraits. There is no special way to extract the photos of school-age children and "look at them with the naked eye." This time, the task force brought back more than 300 suspected photos, informed parents to identify them, and finally determined more than 170 objects. But the DNA match, none of them match. Looking for someone failed again.
"We will fight Wang Mouwen to the end, we can’t lose, but it is difficult to find a breakthrough." Jiang Xiaoling said that they almost exhausted the means of investigation. "I even went to the local area to find out which school-age children don’t look like their families, but it’s like looking for a needle in a haystack."
In 2017, Sichuan police pushed the information of children to the local area through the help of Tencent QQ, and one child offered a reward of 30,000. At the same time, more than 10,000 circulars were printed and distributed in Shantou. "But the two jobs didn’t work. There were no valuable clues except receiving two calls asking whether the reward information was true or not."
Looking for someone, deadlocked.
On the one hand, there is a deadlock in finding people, and on the other hand, there are fast-growing children. Nearly 10 years after the incident, their appearance has changed dramatically. Traditional means have become more difficult. The turnaround occurred at the end of 2017. At that time, Chen Shiqu, deputy director of the Criminal Investigation Bureau of the Ministry of Public Security, went to Tencent for investigation. Li Xin, a security expert of Tencent Guardian Program, mentioned a new technology of cross-age face recognition. Subsequently, the technology was introduced to the Sichuan police, hoping to break through the case with scientific and technological strength.
Caught in Trap
Cross-age face recognition technology
"Smart" and "mature" algorithms find 7 children.
"At that time, Chen Bureau said that there was such technology and asked us if we would like to try it. We are definitely willing. " Jiang Xiaoling said. In 2018, Sichuan police officially cooperated with Tencent’s face recognition team — — Youtu laboratory docking.
Cross-age face recognition is also a big problem in the world. It mainly learns the natural cross-age change law of face through algorithms and presents the cross-age change of face. The 10 children involved in the case are just in the growth period, with a large age span and great changes, and its difficulty is self-evident.
"It’s very difficult, and I didn’t have a bottom before." On July 3 this year, Li Xin told reporters, "But if we can find these children through technology, it is also of great significance."
Li Xin introduced that the face recognition team of Youtu Lab has done a lot of work for a long time to make the algorithm "smart" and "mature". In order to verify the accuracy of cross-age face recognition, team members also took their own photos for experiments at the annual meeting. What is exciting is that the end result is good.
Sichuan police collected positive photos of all the children from parents and sent them to the technical team. In this regard, Jiang Xiaoling was impressed: "There are not many photos in the hands of parents. After their children are lost, these photos are even more entrusted with all their feelings and thoughts about their children, for fear of losing them."
"After the Spring Festival in 2018, a number of results were produced. One person corresponds to 50 similar people, and the similarity scores are from high to low." Jiang Xiaoling introduced that the abduction police "digested" the data packet for several months, and then carried out ground investigation on the suspected objects with high similarity. In the end, at the beginning of 2019, the success ratio was 4.
"I found it!" This is a result that excites everyone. At that time, Xiao-ling Jiang cried out excitedly, making it difficult to sit down in the office.
Good news continued, and the second batch of 1 person and the third batch of 2 people were successfully found in the next two months. So far, seven abducted children have been found, and the similarity between the successful comparison and the recognition results is over 96.
In May of this year, the CCTV program "Wait for Me" presented this technology to find people. Confirmed by Sichuan police and Tencent, this is the first time that cross-age face recognition technology has been used by the police to abduct and find people.
However, there are also some puzzles. "Among the remaining three children who have not been found, there is a male doll. Every time the comparison is made, the first similarity is the same person. In any case, I think it should be this person, but the DNA can’t match." Jiang Xiaoling said, "We even went to check the birth situation of this child’s parents, but we still didn’t understand the reason."
The kidnapper is a husband and wife.
Looking for, still going on … …
Looking for someone, still going on. With seven children found, Wang Mouwen, who has been sentenced to 15 years, will also face heavier punishment.
The case-handling personnel restored Wang Mouwen’s personal experience to the reporter.
In fact, Wang Mouwen’s first crime occurred in 2006. At that time, Wang Mouwen abducted a child in Hunan. In the process, the child cried and others called the police. Wang Mouwen was arrested and sentenced to 3 years in prison.
"He was released from prison before the 2008 Olympic Games, and then he started committing crimes again." Jiang Xiaoling said that in 2008, 2009 and 2010, he committed 10 crimes, all in some counties or rural areas, taking the children away and then transporting them to Guangdong with his lover. "Accurately speaking, he is responsible for abducting children, and his wife is responsible for transporting them, because women with children are not easy to be suspected, which is ‘ Husband and wife file ’ Commit crimes. "
Judging from the transaction records of Wang Mouwen’s bank found by the police, after Wang Mouwen brought his children to Guangdong to make a profit, he would deposit the money in the passbook, with the amount ranging from about 10,000 to about 100,000.
"The amount that can be verified is at least more than 200,000." Jiang Xiaoling introduced.
In 2010, after earning hundreds of thousands, Wang Mouwen took over and went to Qinghai to start a business. However, in just over three years, Wang Mouwen lost all his money.
In 2014, Wang Mouwen decided to commit another crime. "on the one hand, the technique has been skilled and I feel that the money is fast; On the other hand, I feel that I have done it so many times before, and the police have not caught him. There is no way to take him. " Jiang Xiaoling said, but this time Wang Mouwen was quickly arrested by the police.
At present, the police are doing further work and will increase the punishment for Wang Mouwen through judicial procedures.
