The master of medicine confessed his motive when a friend's family was murdered and dismembered. What happened afterwards?

July 14, 2009, the weather was hot. Due to receiving an alarm from the public, the Gulou police came to the door of a unit on the ninth floor of Lanshan International Apartment on Heilongjiang Road and asked the property to open the door. After that, the air suddenly filled with a smell of blood mixed with stench. There is a female corpse in the corridor, a male corpse in the study and a little girl in the bathroom ... What the investigators never expected was that there was a living person in the room. A man in his thirties was sitting on the sofa blankly. Facing the police, his first sentence was: "Kill someone, help!" " He wanted to leave the scene and was immediately controlled by the police. In addition to the three dismembered bodies, investigators also found some crime tools at the scene. The murderer tried to destroy the body after killing a family of three. After investigation, the murderer who committed the crime in July of 12 never escaped, and had lived at the scene of killing the door for two whole days when handcuffed. The head of the murdered family is Jian Xu, who was a middle-level cadre of Simce Lei Company before his death. Ai Jianguo, a murder suspect, is from Zhumadian, Henan Province, and holds a master's degree in Pharmaceutical University. He worked in another pharmaceutical company, worked as a colleague with Jian Xu for a while, and then left the company to do business with Jian Xu.

Ai Jianguo was then taken to the police station as a major suspect. Ai Jianguo confessed to the murder in his first statement. According to his confession, he and Jian Xu were former colleagues. At about 20 o'clock on July 1 1 2009, he came to Jian Xu's home, struck Jian Xu on the head with a claw hammer, and killed Jian Xu's 7-year-old daughter who was also indoors. Later, he stayed at Xu Jian's house until the next afternoon 16. Xu Jian's wife came home from other places to visit relatives, and he also killed her. After killing Xu Jian's family, Ai Jianguo made it easier for them to live together in the same room. On June 5438+03, he went out to buy tools such as grinders and cutting machines, and returned to the crime scene to dismember the bodies of the three victims. During this period, some bodies were thrown into the manhole under the Jinchuan River Bridge. After the incident was disclosed by the media, the cruel means of killing shocked the whole country. Just when people said that they would severely punish the murderer, Ai Jianguo suddenly retracted his confession and refused to admit that he had killed others. At the same time, Ai Jianguo's motive for killing has always been a mystery, which makes it difficult to finalize the case.

Ai Jianguo himself said that no one can jump to conclusions about the motive of committing the crime. However, the evidence in this case can explain some problems. For example, when Ai Jianguo was arrested, Xu's bank card was in his pants pocket, with a balance of nearly 30,000 yuan. In his temporary residence in Shengli Village, Qixia District, there are three bank cards of his own, and the money inside is pitiful. That is 1 19.07 yuan, 0 yuan, 0.94 yuan.

In the judgment of the first instance, Ai Jianguo heard the death sentence and took the oath on the spot. Ai Jianguo claimed that he "had a sore hand and could not sign" and refused to sign the verdict. "I was coerced" claimed that there were three other men at the scene. When the judge asked how many people went to Xu Jian's house during the trial, Ai Jianguo said that there were three other strange men in Xu Jian's house at that time, all in their twenties, and their height was similar to their own. One of them has a southern Jiangsu accent. Ai Jianguo told the presiding judge that he went to Xu Jian's house because Xu Jian wanted to introduce him to someone and asked him to go. At 5: 30 in the afternoon, he went into Xu Jian's house and found three men at home, so he put down the coffee and biscuits he brought to Xu Jian and prepared to come again another day. Who knows that the three men are not allowed to leave, or they will kill him.

He was so scared that he took out his mobile phone and 1000 yuan in cash to go to the antique market and begged the strange man not to kill him. After that, Jian Xu talked with three men in dialect, but he didn't understand. In the evening, three men allowed him to go out for dinner with the daughters of Jian Xu and Jian Xu. After the payment, Jian Xu went to a nearby bank to withdraw money and return it to him. That night, he slept on the sofa with Jian Xu and his daughter. The next day, Jian Xu's wife Dai Xiaohong went home, and the contradiction between the two sides intensified. One of the three people kept looking at himself, and the other two dragged Jian Xu's family into the study, killed them one by one with a hammer, and arranged for him to go to a nearby garbage dump after dismembering the body. Ai Jianguo, who did everything, survived after the police arrived. When answering the prosecutor's question that he could escape from the control of three men without running for his life, Ai Jianguo said that three men told him that there were snipers outside the community.

Police evidence confirmed 1. After they entered the crime scene, they only found Ai Jianguo. After investigation, the public security personnel confirmed that all windows and curtains in the room were closed, and no suspicious traces of other personnel were found.

A merchant in the hardware hall of Jinqiao Market identified that on the afternoon of July 13, 2009, Ai Jianguo went to his booth to buy steel cutting machines and grinders. After Ai Jianguo paid, he delivered the goods to the Blue Mountain International Gate as required. Ai Jianguo was waiting at the door and took him downstairs.

The clerk of a supermarket near the incident also clearly recognized Ai Jianguo: "He hurried into the store and bought a big shopping bag directly. At that time, he first bought five red' punctuality' mosquito repellent shopping bags. After about ten minutes, he came back and bought 30 transparent plastic bags for our supermarket. "

According to the community surveillance video and witness testimony, from the night of July 1 1, Ai Jianguo entered Room 90 1, and when he was arrested on July 14, he went in and out of the crime scene alone many times, two of which lasted for more than 70 minutes, and entered the decorative city and supermarket with crowded people and complicated environment. If, according to Ai Jianguo's defense, there were three male murderers and snipers followed him, then the three murderers would not have to take great exposure risks and let Ai Jianguo go out alone many times, and Ai Jianguo would have enough time and opportunity to call the police or escape.

Except for the victim, the blood and DNA at the scene came from Ai Jianguo, and a large number of biochemical identification tied Ai Jianguo to the murderer. For example, the DNA of adhesion tissue extracted from Ai Jianguo's sternum is the same as that extracted by Dai Xiaohong. A blood fingerprint of Ai Jianguo extracted from the back of the chair at the scene is the same as Dai Xiaohong's painstaking DNA. The blood DNA extracted from Ai Jianguo's underwear is the same as Jian Xu's painstaking DNA; The DNA of the blood on Ai Jianguo's socks is the same as that of Xu's young daughter.

There were human particles in the cutting machine at the murder scene, latex gloves beside the girl's body, DNA of Ai Jianguo on the right glove, and broken blood bubbles on the index finger and middle finger of Ai Jianguo's right hand. The DNA of the wipe on the hand of the cutting machine was tested and found to be the combination of AI Jianguo's DNA and Xu's daughter's DNA. Based on the above evidence, you can almost imagine the scene of dismembering the body with a cutting machine on one knee.

The judicial appraisal opinionNo.: Judicial Appraisal Institute of Nanjing Brain Hospital (2009) 193 proves that Ai Jianguo was not mentally ill at the time of committing the crime and had full criminal responsibility.

In addition, Ai Jianguo was just arrested and confessed that he wanted to dispose of the bodies of the Xu family of three, and then sold his house without telling Xu's unit. The police found the last pages of five contracts in Xujiazhong, which were printed with "Party A" and "Party B Ai Jianguo" respectively. There is a red inkpad handprint on Xu's name, which is proved to be Xu's left thumb print by identification. This is also strange, because you will use the index finger of your right hand when fingerprinting.

What's the motive? There is really no motive for murder in this case. The defendant Ai Jianguo had a good personal relationship with the victim Jian Xu. Jian Xu and Ai Jianguo met in 2004. At that time, they worked in Zheng Da Tianqing Company as colleagues and subordinates. When Jian Xu moved into Blue Mountain International Apartment in 2008, Ai Jianguo and his brother drove the victim Jian Xu to move. He also introduced his wife Dai Xiaohong's cousin Yao to Ai Jianguo as his girlfriend. Before the incident, Jian Xu worked in Simce Lei. Ai Jianguo runs a company that sells scientific research instruments, consumables and chemical products. Jian Xu introduced Ai Jianguo to the purchasing manager of the synthetic aperture company. Ai Jianguo and simcere have business contacts and have certain business opportunities.

A purchasing manager in Lei, Simce, Jiangsu confirmed that around April 2008, Xu Jian introduced Ai Jianguo to negotiate business with him. After that, the two talked about a pure water machine business. Because Ai Jianguo's quotation was too high, it was later ruined. Ai Jianguo followed him many times and threatened him. An executive of Xiansheng Pharmaceutical Research Co., Ltd. said that in 2006, Ai Jianguo took the initiative to talk to him about business, claiming to be a former colleague of Jian Xu. His company and Ai Jianguo * * *, made seven transactions, with a total payment of 540 14 yuan. Around 2007, the company negotiated a deal with Ai Jianguo, worth 780,000 yuan. According to the regulations, Ai Jianguo needs to pay half of the payment, but he can't pay and the business is not done. "Jian Xu has helped jian-guo ai so much. According to the understanding of ordinary people, it is too late for Ai Jianguo to thank Jian Xu. " Cai said that Ai Jianguo had no deep hatred to kill Jian Xu's family anyway. Why on earth did Ai Jianguo commit a rare murder for many years? Judging from his present attitude of confession, I'm afraid no one will ever know.

According to Ai Jianguo's own account, the economy was very tight before the incident, and the figures on the bank card had reached a single place. Ai Jianguo confessed that in order to solve the problem of separation between husband and wife, Xu Jian wanted to buy a house in Nanjing and settle down, so he borrowed money from Ai Jianguo, but did not write a loan. Ai Jianguo said in his first confession that Jian Xu had been dragging his feet and didn't want to write an iou, so he decided to go directly to Xu Jianjia. On July 12, 2009, he came to Xu Jian's house and saw Jian Xu's 7-year-old daughter watching TV, while Jian Xu's wife was not at home, so Ai Jianguo told Jian Xu that he would not leave because there was no explanation for borrowing money. At 4 o'clock in the afternoon, Jian Xu's wife Dai Xiaohong came back. Although AI Jianguo had been introduced to someone before, Dai Xiaohong pretended not to know him when he saw him, and then chatted with her husband in Wuxi dialect. Ai Jianguo didn't understand a word.

Dai Xiaohong thought that her husband would not borrow money from Ai Jianguo. When Ai Jianguo asked whether Jian Xu had borrowed 300,000 yuan from himself, although Dai Xiaohong blinked and hoped that Jian Xu would deny it, Jian Xu admitted it, so Ai Jianguo asked Xu Jian to make a written statement, but Dai Xiaohong refused. Ai Jianguo confessed that he was going to find a debt collection company to solve the problem and prepare to leave Xu Jianjia.

At this time, Ai Jianguo saw Dai Xiaohong holding a hammer to hit him. He jumped up at once and grabbed the hammer to hit him. Dai ran into her daughter's bedroom and locked the door. Ai Jianguo kicked the door open and locked it again. He took a hammer and said to Dai, who was curled up in bed, "I can't stand it no matter how strong I am!" " Dai Xiaohong immediately responded: "You hit you!" After slapping Ai Jianguo three times, Dai added: "Although I am not very good-looking, I enjoyed everything I should. You're not married. It's worth killing me! " Ai Jianguo added, "Jian Xu is my eldest brother. I'll send you on the road for my eldest brother and find another woman ten times stronger than you. " After that, Ai Jianguo tried his best and hit Dai on the head with a hammer. With a loud cry, Dai fell to the ground and said, "It's over." Ai Jianguo then gave Dai a hard knock on the back of the head, and Dai suddenly stopped. Later, Ai Jianguo opened the door and let Jian Xu in. Jian Xu was stunned when he saw the scene of his wife's tragic death. Jian Xu pulled Ai Jianguo to the bathroom, knelt down and begged him, saying that he could sell his house to pay off his debts, and begged Ai Jianguo to let him and his daughter go. Ai Jianguo said that they can get rid of the body and help Jian Xu find a good woman, and the expenses can be paid by him. Seeing that Jian Xu didn't listen to his advice, he just begged him to let himself and his daughter go. Ai Jianguo thought that Jian Xu didn't believe him, so he killed Jian Xu with several hammers. He felt that the little girl saw the whole process of her being killed, dragged her into the bathtub in the bathroom and killed her with a hammer.

Jian Xu's family speculated that Ai Jianguo killed Jian Xu largely because he took a fancy to Jian Xu's beautiful house in Blue Mountain International. Because after killing Xu, Ai Jianguo downloaded and printed a standard house sales contract on the computer. He dragged the dead Jian Xu's finger, pressed his handprint and signed the names of both parties, in an attempt to transfer Jian Xu's house to his own name in the form of business. He also plans to go to Xu Jian to announce his resignation, and use Jian Xu's mobile phone to send text messages to contact his family, so that others will think that Jian Xu's family is still alive. This speculation has also been partially confirmed by the staff of Nanjing Legal Aid Center. At the beginning of this year, Jian Xu's brother and sister-in-law came to the Nanjing Legal Aid Center to apply for legal aid for the incidental civil litigation involved in the murder of his younger brother's family of three. Jian Xu's brother-in-law said that Jian Xu developed from his hometown to Nanjing and got married after hard struggle. It wasn't long before he bought a house in Blue Mountain International, and his life just settled down. Jian Xu's brother-in-law said that the murderer Ai Jianguo had planned to enter Xujiahui. They estimated that Ai Jianguo had the idea of Xu Jianjia's real estate before the murder, because he printed a power of attorney on the computer to the effect that Jian Xu entrusted Ai Jianguo to handle their real estate in Blue Mountain International Apartment. After killing Xu Jian's family of three, Ai Jianguo put Mr. and Mrs. Jian Xu's fingerprints on the power of attorney in an attempt to smash the house with a forged power of attorney.

Ai Jianguo, 34, was single before the incident and had no girlfriend. The deceased introduced his wife Dai Xiaohong's cousin Yao to Ai Jianguo as his girlfriend. But this relationship has no result. Cousin Yao said after the incident that around the Spring Festival in 2009, her brother-in-law introduced her to talk with Ai Jianguo. Since then, she and Ai Jianguo have sent several short messages to each other. During the contact, Yao felt that Ai Jianguo's thoughts were eccentric and took the initiative to interrupt his feelings with Ai Jianguo. It is speculated that after Ai Jianguo's lovelorn love, he did not rule out his revenge on Yao's brother-in-law and sister Dai Xiaohong, and killed Xu Jian's family. However, the judicial staff who have contacted Ai Jianguo believe that this possibility is not great.

In view of Ai Jianguo's poor family, bumpy growth track after work, introverted and irritable personality, Ai Jianguo's defense lawyers believe that the most likely reason for Ai Jianguo to kill Jian Xu's family is jealousy. Lawyer Cai believes that Ai Jianguo has a good relationship with the past. On July 12, 2009, Ai Jianguo went to Xu Jianjia to borrow money from Jian Xu, because Jian Xu, who held an important position in a pharmaceutical company at that time, earned 200,000 yuan a year. Ai Jianguo may borrow money from Jian Xu, but the amount that Jian Xu refuses or lends on the spot is far below Ai Jianguo's expectation. Seeing that Xu Jiansheng was living so well, Ai Jianguo, who also graduated with a master's degree, was psychologically unbalanced, from envy to jealousy, and suddenly broke out, killing Jian Xu and his daughter. Combined with his first confession, before Jian Xu died, Ai Jianguo may have forced him to transfer the house to himself, because Jian Xu's blood was found on the murder weapon hammer.

On July 7, the "blue mountain international apartment murder tragedy" that shocked Nanjing was pronounced in the first instance. Ai Jianguo, accused of hammering and brutally dismembering a family of three friends, was sentenced to death by the Nanjing Intermediate People's Court for intentional homicide. Ai Jianguo resolutely faced the verdict and said that he would appeal ―― the 34-year-old master of medicine kept saying that "the killers were three other people".

Although Ai Jianguo denied murder, there is sufficient and conclusive evidence in this case to prove that Ai Jianguo committed murder and dismemberment. Finally, the Jiangsu Higher People's Court upheld the first-instance judgment and submitted it to the Supreme People's Court for approval. On the afternoon of 2011August 12, Ai Jianguo, a master of medicine, was taken to the execution ground by the Nanjing Intermediate People's Court of Jiangsu Province.
