    After finishing the interview, Ye Qian obtained a copy of Su Yu's ID card from the factory personnel department. Regrettably, the address registered in the address column of the ID card was "Village Group No. 32, Suoqiao Village, Yunxi City, Wannan Province"  ".  Obviously, this should be Su Yu's registered residence, not his current residence.

    The easiest way to prove whether the deceased is Su Yu is to do DNA matching of direct blood relatives.  Unfortunately, after many investigations, it was found that Su Yu was born in a single-parent family. His mother passed away many years ago. His brother went out to work a few years ago and there has been no news.  Su Yu also has a sister-in-law who is currently out of contact.  As a result, there is no DNA sample available for comparison.

    Since there is no way to find directly matching DNA samples, the only way to prove it is indirectly.  After checking Su Yu's household registration file, it can be determined that he was born and raised in Suoqiao Village.  As long as the DNA of the deceased and Suoqiao Village can establish a blood relationship, it can be determined that Su Yu is the headless male corpse.

    According to genetic research, human chromosomes have 23 pairs and 46, of which 22 pairs are called autosomes. The autosomes in men and women are the same; the remaining pair are called sex chromosomes, which are different in men and women. The pair of sex chromosomes in men are composed of  It consists of one x chromosome and one y chromosome and is written as xy. In women, it consists of two identical x chromosomes and is written as xx.  During the formation of sperm, the germ cells undergo meiosis, and the chromosomes in the nucleus, including autosomes and sex chromosomes, are divided into two. At this time, half of the sperm carry X sex chromosomes, called X sperm; the other half of the sperm carry  Those with Y sex chromosomes are called Y sperm.  In the process of inheritance, if the x sperm combines with the egg, the next generation will be female; if the y sperm combines with the egg, the next generation will be male.  In other words, the y chromosome from the father will continue to divide and combine in the family.  Therefore, the y chromosome is also called a family gene.  In rural areas, it is common for families with the same surname to live together. We only need to compare the Y chromosome of the deceased with the Y chromosomes of the eldest, middle and young males in Suoqiao Village to find out whether the deceased and Suoqiao Village are related by blood.  Fortunately, the results of the comparison were exciting. The Y-chromosome genotype of the deceased was the family gene of Suoqiao Village. In other words, the headless corpse was Su Yu who had been missing for many days.

    In order to further verify, Su Yu¡¯s registered residence is our next focus of investigation. After Team Xu applied for the relevant legal procedures, we came to the village group No. 32 of Suoqiao Village.

    There are three bungalows on the center site facing south and facing north. They cover a large area of ??more than 200 square meters and are arranged in an inverted "L" shape in the yard.  Just as I was using hydraulic pliers to cut the door lock, the weird atmosphere in the yard began to make us shudder.

    There is a vegetable field in the southwest corner of the yard. A grave bag is piled up in the center of the vegetable field. There is a wooden sign in front of the grave, which reads in red paint: "Tomb of daughter Li Yanmei."

    "Li Yanmei?" Ye Qian took out her notebook and flipped through it carefully, "Yes, she is Su Yu's sister-in-law. Didn't the village director say she has been missing for several months? How could she be buried in her yard?"

    "It seems that things are more complicated than we imagined." I pointed to a large series of messy footprints in front of the grave. "It completely matches the shoe sole pattern of the suspect in the headless corpse case. There are two and a half shoe prints directly in front of the tablet.  There are two depressions in front of the shoe prints, and the suspect once knelt down in front of the grave."

    Brother Ming¡¯s face turned extremely ugly: ¡°Ye Qian, is it possible that Su Yu¡¯s brother can¡¯t be contacted either?¡±

    Ye Qian took another look at the notebook: "Yes, the village director said that Su Yu's brother went out to work several years ago and has been unable to be contacted. He has never come back during the holidays."

    Brother Ming: "I now suspect that this is a premeditated revenge killing. Inform Brigade Xu to send more people, and then contact the police station in the jurisdiction. No matter what method you use, you must contact Su Yu's brother."

    "Okay, Director Leng, I'll do it now." (Remember the website address: www.hlnovel.com
