Red Star News Network, March 7.
In the Chengdu Wuhou Public Security Criminal Science and Technology Office, there are three such ones.
Liu Jing: Mao Sui recommended himself to do criminal skills, and he was impulsive this time in his life.
In 2022, Liu Jing knocked on the office of Zhang Heng, director of the Criminal Science and Technology Office of the Sub-Bureau, and came to a self-recommendation, and it took her 7 years to make this decision and take this step.
In 2015, when Liu Jing first joined the Chengdu Wuhou Public Security, she was assigned to the patrol police brigade, and she stayed on duty in the Flying Eagle Commando and the gun storehouse, and also worked in the office for several years, but there was something in her heart that she couldn't let go.
Coming to the Criminal Science and Technology Room, Liu Jing was able to exert his strengths. In May 2023, a woman reported her encounter to the police, hoping to find a breakthrough in the fragmented information.
Eventually confirmed as the same person.
Starting from a subtle screenshot, supplemented by voiceprint identification technology, and using big data intelligence analysis, Liu Jing persevered for three months to successfully highlight the suspect. After verification, there were 29 cases of collusion and merger, and the amount involved was as high as 7 million+. This case was reported to the Ministry of Public Security as a classic case of breakthrough in voiceprint identification, and Liu Jing also used the case as a traction to refine the selection competition.
Li Shan: Concentrate on interdisciplinary study, break through obstacles just to realize your dreams.
In the same office, there is a young girl who is as persistent as Liu Jing to realize her dreams.
In 2014, Li Shan was admitted to Sun Yat-sen University majoring in biomedical engineering. In this special major that integrates life science, engineering technology and medicine, she learned about life science and medicine, learned engineering skills such as programming and engineering drawing, and has a multidisciplinary knowledge background in science, engineering and medicine. When choosing a job, the long-dormant heart burned again. Without the slightest hesitation, Li Shan applied for the postgraduate examination of the Criminal Technology major of the China Criminal Police Academy, and succeeded in the first battle.
After graduation, she came to the Criminal Technology Room of the Wuhou Branch, and Li Shan's growth pace was fast and steady, and she was able to bloom here. Under the leadership of Gui Gaofeng, the master and apprentice ran through the intricate crime scene, looking for the truth and deciphering the code from the clues; Under the guidance of her senior brother Zhou Fan, she hid behind the investigation of the crime scene in the cyber virtual space, concentrated on overcoming various problems in the examination and identification of voiceprints and electronic physical evidence, combined traditional and new physical evidence for in-depth research, and let technology support the investigation, lead the investigation, and serve the investigation.
In less than two years of work, Li Shan has been out of various criminal cases more than 100 times, extracted more than 100 cases of physical evidence, issued more than 60 fraud case scene analysis and judgment reports, and provided more than 20 voiceprint clues. Last year, Li Shan also represented the Chengdu Municipal Public Security Bureau to participate in the provincial department, competing with a group of experts, and won unanimous praise from the leaders of the provincial department for her professional skills and perspective.
Be sure to chase it to the end.
Liu Xiaoyu: Devoted to intoxication with fingerprint comparison, twenty years of hard work.
In front of Liu Jing and Li Shan, Liu Xiaoyu can be called the leadership of the Criminal Science and Technology Office, she quickly got started with the scene investigation, and then the focus of her work gradually tilted towards fingerprint comparison, and this work has been done for 21 years.
When asked about Liu Xiaoyu's work achievements over the years, she always said that even she herself did not realize that her work had made great contributions to the investigation and solving of cases and the maintenance of law and order.
One night in early August 2013, a burglary occurred in a community on Jinchuan Road in Wuhou District, and cash was stolen 1270,000 yuan and countless valuables such as laptops, tablets, watches, and mobile phones. Restricted by the best monitoring conditions, the most important thing left at the scene is fingerprints, and this heavy responsibility falls on Liu Xiaoyu's shoulders.
After returning to the unit in the early morning, Liu Xiaoyu immediately edited and entered the on-site fingerprints extracted by the on-site investigators into the fingerprint system, which coincided with the city's period, and the fingerprint system compared the huge number of cases and the slow response to the comparison, but Liu Xiaoyu still insisted on staying up late in the unit and waiting for the results. After waiting patiently for nearly 4 hours, he finally hit the suspect Zhou. Considering the impact of summer sweat on the clarity of fingerprints, Liu Xiaoyu conducted repeated verification and comparison, confirming that the fingerprint at the scene was the same fingerprint as the finger on Zhou's left hand, and locked the direct suspect for the detection of the case.
The hanging hearts of the surrounding residents finally calmed down.
Around us, there are many outstanding female policemen like them, who shine in their own fields and promote the high-quality development of public security work. Approaching International Women's Day, salute the outstanding ones!
