However, after careful identification by the Sichuan Provincial Department, there were no biological samples on the felt hat that could identify the murderer. The investigation lasted for more than a year, and the task force was later disbanded due to the lack of progress in the case. The investigators in charge of the investigation had no choice but to sort out the 15 thick files and put them in the archives. But at the same time, they also secretly resolved in their hearts that one day, they would definitely bring those two vicious gangsters to justice. So, they took good care of the only piece of physical evidence, the felt hat, hoping to use it to identify the killer one day in the future. ”

Time flies, and with the gradual improvement of the application of DNA technology in criminal investigation, the Ziyang police decided to restart this big case that has been sealed for many years. This time, they found the best appraisal agency in the country that is currently in this field. After more than half a month of waiting, the good news finally came that made everyone excited. ”

"The technician extracted a (note this unit, it is a) exfoliated cells from the felt cap, and compared them to the warehouse, and found a suspect, 49-year-old Liang Kaiwu. This Liang Kaiwu, a native of a county under the jurisdiction of Ziyang, had co-robbed a silk warehouse more than one year before the crime, that is, in 2001, and took the opportunity to escape on the way back from the identification scene. The local police have also been looking for him for a long time, but he has been on the run. ”

Ziyang's case-handling staff immediately rushed to Liang Kaiwu's house. His family said that this person liked to steal chickens and dogs and fiddle with firearms since he was a child, and his family couldn't control him and rarely contacted him. ”

And according to Mr. Liang's family, after the 2001 case, he and his cousin, Shi Shengqiang, who co-founded the crime, went to Feng County, Shaanxi Province, to open a restaurant. And the village where their restaurant is located is the closest to the railway crossing where the armed police soldier was killed in August 2002! What's even more coincidental is that more than a month after the gun seizure case, Liang Kaiwu and Shi Shengqiang closed their doors, and more than a month later, the Sihai Group gun case occurred. ”

As a result, the police believe that Liang Kaiwu is suspected of committing a major crime. Through many inquiries, Liang Kaiwu was finally caught in Suining, Sichuan. After arriving at the case, he only admitted to the theft case in 2001, but flatly denied that it had anything to do with the Sihai Group case. However, it was useless not to admit it, and the investigators found a large number of photos of his homemade pistol in his mobile phone. After interrogation, he confessed that there were several homemade guns buried under a tree in front of his house. Note that Cao Jianqiang, a soldier of the armed police, was killed by a homemade pistol. ”

And as the police talked to Liang Kaiwu's family, his father said that Liang Kaiwu had hidden a package in the cellar of his family many years ago. The investigators found and opened the package, and what appeared in front of everyone was a military submachine gun. Although the number on the gun has been erased, when the internal number and ballistics are analyzed, this is the gun that the armed police soldier was robbed and killed the cashier Zeng Wen. ”

In front of the evidence, Liang Kaiwu had no choice but to confess that after they fled to Feng County, they wanted to do a big deal. Because he had sold pigs to the Sihai Group before, he knew that the Sihai Group was easy to rob in the early morning. And because the pig dealers at the scene had machetes and other tools, Liang Kaiwu was afraid that his self-made pistol would not be powerful enough, so he thought of grabbing the gun. After discussing with Shi Shengqiang, he decided to attack the sentry of the railway sentry, because the sentry was only one person standing guard, and it was far away from the barracks, so it was not easy to be discovered. ”

"At about 0:00 p.m. on August 30, 2002, Liang Kaiwu came to the vicinity of the sentry box that had already stepped on the point with a gun, and when a train passed by, he took out his gun and was about to aim, when the sentry's wolf dog barked, and at this time, the soldier Cao Jianqiang also seemed to have discovered Liang Kaiwu, so Liang Kaiwu took the first step to shoot Cao Jianqiang's head, and then grabbed the gun and fled. In order to be discovered, he buried the gun in the mountain, and it took more than a month before the limelight had passed before it was dug up and brought back to Ziyang. ”

In the early morning of December 1, he pretended to be a pig dealer and infiltrated the factory of Sihai Group, and then carried out a robbery and murder plan. The person who answered him at the door was his cousin Shi Shengqiang. After the two fled the scene, when they passed the railway crossing, due to the bumps, his felt hat also fell off, and he did not have time to pick it up. ”

Hearing this, I couldn't help but ask, "Caught?" Case closed? ”

Zhang Bin looked at me as he should: "Of course, otherwise you can let him run away?" You must know that the French Open is restored and not leaked, how can it be possible for him to escape! Don't speak, I'll give you another case. ”

"In the early morning of June 30, 2003, on Dezhou Island, an island located in the sea near Shantou City, Quang Bei Province, the staff of the Maritime Safety Bureau found a very strange box on a reef by the sea when they got up to clean up."

"On the outside of the box was an iron frame welded with water pipes, and iron chains were wrapped around it. The staff said that this strange box was a bit weird, so they decided to call the police. Based on the direction of the case in this building, you should have guessed it all. In the midst of the extremely pungent stench, it was natural that the investigators found a highly decomposed corpse curled up in the open box, and what was even more terrifying was that the corpse only had a torso and no head. ”

"After a great forensic examination, the deceased was a woman, in her 20s, 1.6m, and the time of death was about a month. A further autopsy revealed a cat-like tattoo on the deceased's thigh near the knee. ”

"The first step in the nameless corpse case is to determine the source of the body. Since Texas Island is a small island only the size of three football fields, there are no residents on the island, and only two staff members of the Maritime Administration are stationed on the island to be responsible for the work of the navigation tower. Therefore, the investigators speculated that the box should have floated from the urban area of Shantou, which is only a few kilometers away from the island. In the police investigation of the recent missing persons in Shantou, no one was found to be consistent with the headless corpse. Obviously, the murderer cut off the deceased's head for fear that the police would find out the identity of the deceased. ”

"If it weren't for the local missing people in Shantou, where would the deceased come from? Then, the medical examiner will find two incredible things in the autopsy that will play a major role in finding the deceased - two silicones for breast augmentation. ”

The police took the silicone bra to the plastic surgery hospital staff for identification, and they said that it was a British brand of breast augmentation silicone, and this silicone has a general agent in China, and all the general agents of sales records are registered. This is good news for the investigators who can't find the source of the body. Soon they went to the agent in Wuhan and got a form from them. A total of 29 silicone pieces of the brand were sold in China to 15 patients in more than 10 plastic surgery hospitals. Each patient had their contact information, and the police contacted 14 of the women, except for Qingqing, a young woman who had surgery in Zhuhai. So will Qingqing be the deceased? ”

The police quickly found a plastic surgery hospital in Zhuhai and quickly obtained Qingqing's identity information from the hospital. She is a native of Guangxi and was born in 1991. The hospital said that Qingqing is a girl who loves beauty, and has undergone a total of 6 plastic surgeries in their hospital, the most recent of which is breast augmentation surgery. The originally scheduled follow-up visit on June 10 did not show up, and the hospital felt strange. ”

The police then contacted Qingqing's family in Guangxi, who said that Qingqing's phone suddenly became unreachable after June 8, and they were also in a hurry. In order to confirm that the deceased was Qingqing, the police also asked Qingqing if she had a cat tattoo on her body, and received a positive reply from the family. And later DNA identification also confirmed that the headless female corpse was Qingqing. At the same time, she is supposed to have disappeared on June 8. ”

Immediately, an investigation into Qingqing's whereabouts before and after her disappearance and her personal social networks began. The police found that Qingqing usually lives in Zhuhai, and on June 6, two days before her disappearance, she and her boyfriend, a Hong Kong businessman, went to Shenzhen together. Her boyfriend went abroad for business that day, while Qingqing stayed in Shenzhen and stayed at a friend's house. Friends said that one of Qingqing's big hobbies is to take personal photos. At 3 p.m. on June 8, she asked a photographer to help her take a photo. By accessing her call records, the police found that the last call was made to her by the photographer at 2.42 pm on the 8th. ”

"So will the photographer know Qingqing's whereabouts? The police found the photographer, and he said that in the afternoon, several of them set up the police, but Qingqing did not show up, and they could not get through to her phone, so they also contacted Qingqing's friends to complain about her behavior of herding pigeons. ”

After that, some of Qingqing's personal emotional life was also grasped by the police. Qingqing is a junior, her so-called boyfriend actually has a family, is a wealthy Hong Kong businessman, has been dating for more than 2 years, and treats her very well. At the same time, she also has an online dating partner, but the suspicion of these two people has been ruled out. ”

"From the perspective of acquaintances, it seems that there is no breakthrough at all, so the police began to investigate the whereabouts of Qingqing's personal finances after her death - when she was found, she did not have any documents or wallets, mobile phones and other items on her body, and her friends said that she had 2 mobile phones. Soon, the police who were tracking down her bank information found out. She had a total of 6 cards, one of which was withdrawn in three installments totaling 59,000 yuan after her disappearance, or even after her body was found by the police, and the bank's surveillance also recorded the appearance of the person who withdrew the money. But this person clearly has a strong sense of anti-reconnaissance, and each time he performs various facial disguises - wearing glasses, hats, bandages, grimacing, etc., although it is clear that they are all the same person. ”

And the more important clues come from the tracking of the whereabouts of Qingqing's mobile phone. The investigators who had been working hard to find the whereabouts of Qingqing's mobile phone in the periphery found that Qingqing's two mobile phones were sold in an electronic market in Shenzhen. ”
