In the afternoon of the next day, Gu Liao returned to the criminal police detachment of the city bureau again. Although Qiao Sheng impatiently drove him back to rest as soon as he saw him, he still insisted on participating in the case discussion meeting of the task force.

Originally, before listening to reports from all sides, Gu Liao did not have much hope for the progress of the investigation of these two cases. He never dreamed that overnight, the police not only had very important evidence of the crime, but also the identity of the suspect had been basically determined.

The reason why there was such a huge breakthrough in the case was all due to Qi Ruonan, a trace inspector from the Criminal Technology Section.

Yesterday morning, after a brief look at the scene of the crime, Qi Ruonan and Xiang Feng of the technical department still stayed at the scene to continue looking for clues. Although the cunning murderer did not leave any fingerprints and footprints at the scene of the crime, the careful Qi Ruonan found a short yellow hair on the bathroom sink.

The female victim, Luo Yuxin, had long black hair, and the male victim, Luo Mingjun, had short black hair, and this yellow hair was obviously not the one of the two victims. Thinking that the murderer might wash away the relevant evidence in the sink in the bathroom after the murder, Qi Ruonan handed over the hair to the teacher of the physical evidence department for testing.

This time, the god of luck finally sided with the police. The hair that Qi Ruonan picked up had intact hair follicles on it, in other words, the possibility that such hair could detect DNA is very high.

Just two hours ago, they had received exciting news from the Forensic Evidence Division. The hair that Qi Ruonan picked up was not only able to detect DNA, but also found a matching owner in the police's DNA database.

This result is even more surprising to say. Because they found out that the DNA was not left by someone else, it was the perverted murderer who committed six cruel corpse mutilation cases between 2012 and 2013 - Wei Chiliang.

The so-called wise man must make a mistake in a thousand thoughts, and no matter how smart a person is, he will inadvertently make a mistake. An extremely small negligence exposed Wei Chiliang's new crime, so that the police finally saw the hope of solving the case.

Because of this astonishing discovery, the facts of the case have become very clear.

The suspects in the "1.13 Lanting Villa Homicide Case" and the "1.29 Guanghua Community Double Corpse Case" are Chi Liang, a serial murderer who has been wanted by the police for more than two years. He disappeared for a long time, and now he appeared in R City, killing his biological father Yu Chilong, stepmother Luo Yuxin, and Luo Mingjun, who happened to appear at the scene of the crime.

From the perspective of the motive for committing the crime, Wei Chiliang does have some long-standing grievances with the victim. Because most of the people in the task force had not participated in the investigation of the serial murder case a few years ago, and they did not know much about Wei Chiliang's personal background, Qiao Sheng took this opportunity to give them a general description of Wei Chiliang's growth experience.

Of course, to talk about these, we must first briefly understand the family history of the victim Yu Chilong.

In the late 80s of the 20th century, like many intellectuals, Yu Chilong followed the trend of the times, gave up his stable but low-paying job in a state-owned enterprise, and went to the sea to do business.

At first, his road to riches was not smooth, and his lack of experience and mistakes in market prediction soon made him lose money, and he lived a very embarrassing life for a while. But Yu Chilong is not a person who gives up easily. He borrowed some money from relatives and friends and started over under great pressure. It was at that time that a noble man appeared in his life, and from then on, his life took a completely different path.

This person is Yu Chilong's first wife, that is, Yu Chiliang's biological mother - Liu Dongxia.

The Liu family is a well-known wealthy silk merchant in Jiangsu and Zhejiang, with two sons and a daughter. Because of their brothers helping to run the family's business, their youngest daughter Liu Dongxia never had to worry about business matters, let alone give up her pursuit in order to take over the family's industry.

Liu Dongxia has a gentle personality, delicate and exquisite, and is a typical Jiangnan woman. She has loved painting since she was a child, and she wants to walk around the outside world, see more beautiful things, and meet more people. In 1983, she was admitted to the university in R City and studied her favorite major in oil painting.

At an art exhibition one year, Liu Dongxia and Yu Chilong became attached because of an oil painting, and a beautiful relationship began from then on. Although at that time, Yu Chilong's career was just starting and he was penniless, but the rich lady chose the object of her choice, often not caring about the other party's property, but more interested in the other party's character, appearance and talent.

Yu Chilong is a high-achieving student who graduated from Zhejiang University, which was already a very good academic qualification back then. Not only that, Yu Chilong also has the ability to appreciate art, and has a special love for oil painting and sculpture. There are always endless topics to talk about when two people are together. For them at that time, life was extremely happy. That happiness goes far beyond the pleasures of money, but by the time they realize it, life has already changed beyond recognition.

Yu Chilong was lucky, his relationship with Liu Dongxia was not interfered with too much by the Liu family. In the spring of 1988, the two who fell in love with each other finally became married, married and formed a happy and beautiful small family. In 1990, Liu Dongxia gave birth to a smart and lovely son to Yu Chilong, named Liang, which means beautiful and kind.

With the funding of the Liu family, Yu Chilong's business gradually got on the right track, and it didn't take a few years for him to make a name for himself in the real estate industry. Although Liu Dongxia was born in art, she is the daughter of a wealthy businessman in Jiangsu and Zhejiang, and she has had an extraordinary economic acumen since she was a child, and she has given Wei Chilong a lot of help in business. With such a smart and reliable virtuous helper, Yu Chilong's life was like receiving the help of God, and he went very smoothly along the way.

By around 2000, Yu Chilong was already a relatively successful businessman, and he was well-known in R City. This is rich in hand, and there are more rights and wrongs around him. It is said that men will become bad if they are rich, although this is not absolute, but Yu Chilong does not seem to have escaped this curse.

Since Wei Chilong lived in a mansion and drove a luxury car, after becoming famous, even if he didn't take the initiative to find others, there were always some young and beautiful girls around him who took the initiative to seduce him. Those women don't care whether he has a family or not, whether he has a wife and children, and they just want to sell their youth and body in exchange for the luxurious life they need from Yu Chilong.

At the beginning, Yu Chilong just carried Liu Dongxia on his back to raise a little lover outside. At that time, although his body had some infidelity, he still loved his wife very much in his heart. It wasn't until the summer of 2002 that Yu Chilong met a young girl named Luo Yuxin, and his beautiful and happy life was completely disrupted.

I don't know what kind of "witchcraft" I fell into, Yu Chilong was fascinated by that little vixen, and the feelings that were originally just casual play finally evolved out of control. In order to be with Luo Yuxin, Yu Chilong ruthlessly abandoned his wife who was kind to him and restarted his family.

After the divorce, Liu Dongxia was heartbroken and fell seriously ill. After returning to her parents' home for a period of time, in order to have a new start, she resolutely left China, left her parents and brother who were worried about her, and went to Chicago, USA, to continue her art studies at the art academy there.

Although she went to the United States, her heart remained with her son. On lonely and lonely nights, she would always dream of her son parting with her in tears. Soon after arriving in the United States, she realized that she couldn't be a selfish woman and couldn't just leave her poor son alone. She called Wei Chiliang and promised that she would definitely find a way to take him to the United States to live with him as soon as possible.

At that time, Wei Chiliang was only twelve years old and had just graduated from elementary school. He misses his mother very much and looks forward to the news from her from the United States every day. In his heart, his father and the vixen who drove away his mother were undoubtedly the worst villains in the world, but when he thought that he would soon go to the United States and never have to live with these two people again, many beautiful longings surged in his heart.

In order to adapt to life in the United States, Wei Chiliang began to study English hard, and his academic performance improved by leaps and bounds, which impressed teachers and classmates. Although the waiting days are long and torturous, because of that small expectation in my heart, life is not completely without fun.

Suddenly, one day, the expectation came to an abrupt end, and a school shooting in Chicago, USA, was like a thunderbolt from the sky, completely shattering all his hopes for the future.

For a long time, Wei Chiliang couldn't believe that the mother who had promised him to take him to live in the United States had disappeared from his life without a trace. Even if he didn't eat, drink or sleep every day, and stayed by the phone day and night, his mother couldn't call him anymore, care about his life and study, and practice conversation with him in fluent English. Even though he stood in front of the villa every day, waiting for a gentle and kind woman to come to the door and say to him with a smile: "Ah Liang, my mother is here to pick you up." "That person will never be seen again......

Even if he no longer believes it, the separation of yin and yang has become an unchangeable fact.

"Ah Liang, in two months, my mother will be able to complete the formalities to take you here to study. You have to wait for your mother at home obediently, and your mother promises you that she will never leave you again. ”

"I will......" These were the last three words Wei Chiliang said to his mother. From then on, there was nothing to look forward to in his life......
