A seemingly deadlocked case found a breakthrough through a small delivery note. Faced with the suspect's silence, law enforcement officers conducted meticulous investigations and accurately captured the details of the case from massive information, cutting off a long-standing smuggling black chain. On the night of January 8, 2025, the Wenzhou Coast Guard Bureau in Zhejiang Province received a report from the public that there was an unnamed ship near Leqing, Wenzhou, which was suspected of illegal modification. It repeatedly docked at a remote and unmanned dock at night, secretly loading and unloading goods, and its appearance was very suspicious. After receiving the alarm, the bureau quickly organized law enforcement forces to conduct an investigation. After days of surveillance and investigation of clues, a smuggling gang led by Zhang and Lin gradually emerged, and their organizational structure and modus operandi were also gradually grasped one by one. The law enforcement officers immediately set up a sea land joint and multi-point encirclement "sky net" in the target sea area and multiple suspicious ports. On the night of January 25, 2025, after more than seven hours of nighttime surveillance, law enforcement officers finally discovered the suspected ship. The law enforcement boat seized the opportunity and quickly approached, sounding its siren and shouting to stop the ship for inspection. However, the suspected ship refused to cooperate and accelerated its frantic escape. The on-site commander was calm in the face of danger, commanded the law enforcement boat to get close, successfully carried out gang jumping boarding inspection, captured three suspect, Yang, Zhang and Lin, and found 118.9 tons of frozen goods without legal procedures. Faced with overwhelming evidence, Zhang, Lin, and others only admitted to committing the crime for the first time and avoided discussing past crimes, attempting to cover up their long-term and repeated smuggling crimes. The investigation of the case was temporarily deadlocked. In the face of difficulties, law enforcement officers adjusted their strategies and carefully sorted out the data involved in the case again. At this moment, a delivery note with a weight of 25kg stored in Lin's hand caught the attention of the law enforcement officer. Taking this as a breakthrough point, law enforcement officers divided into two groups to conduct investigations. On the one hand, they visited the courier and retrieved a fixed chain of surveillance evidence, while on the other hand, they launched a psychological attack on Lin. In the face of conclusive evidence, Lin's psychological defense line completely collapsed, and he truthfully confessed to the criminal facts of smuggling with Zhang, Yang and others 12 times from September to December 2024. As the investigation deepens, the "upper house" Mr. Gao gradually emerges. Gao, a former criminal, did not repent after serving his sentence and formed a partnership with others to organize a larger illegal activity of smuggling frozen goods, which was more covert. His anti reconnaissance consciousness is extremely strong, and he frequently travels to Henan, Shanghai, Liaoning and other places for remote command, attempting to cut off the investigation clues. Faced with this cunning opponent, law enforcement officers traced and searched through massive amounts of information, gradually identifying their hiding place and criminal evidence. In April 2025, after several days of strict surveillance, with the cooperation of the public security organs, the "mastermind behind the scenes" Gao, who had been running rampant in many places and repeatedly evading pursuit, was arrested in Henan. In this case, more than 1400 tons of smuggled frozen goods were seized, with a value of over 80 million yuan. Gao and others were sentenced to imprisonment ranging from two years and six months to three years in accordance with the law. (New Society)
