Lu Jinping said to Jiang Zhutou: "You are responsible for investigating the source of the corpse, that is, determining who the deceased is." ”

Jiang Zhutou laughed dryly and said, "Sir, this corpse has been burned to charcoal, and it has no appearance, how can I find it?" ”

"It is true that the appearance of the deceased cannot be restored, however, there is a rough age limit, and there is an approximate time of death. Therefore, what you want to visit is the young woman who disappeared during this time, and the deceased is close to ten miles outside the city of Tongzhou, so you should spread around with this as the center, on the one hand, the people in the city, and on the other hand, the people in the surrounding villages outside the city, you must inquire clearly. The job you have to do is to collect the list of these missing people for me, so that nothing is left behind, and this is also very important. Finding the source of the body is often the key to solving the case. ”

Jiang Zhutou nodded and said, "This is no problem, I will definitely do it properly and not disappoint the lord." ”

Lu Jinping looked at Yao Zhutou and said, "You are responsible for spreading around the fire scene to find nearby shepherd dogs, large shepherd dogs, and see who has this kind of dog." It is necessary to make a list of them all, a detailed list, including the basic information of the family, etc. ”

When the three of them heard that Lu Jinping actually asked Yao Zhutou to look for a sheepdog, they didn't understand Lu Jinping's intentions for a while. Yao Zhutou said: "Shepherd dogs are generally used on the grassland, and few people in the city raise this kind of dog. ”

"That's the key, the fewer people who breed this dog, the higher our chances of solving the case," Lu Jinping said. ”

Yao Zhutou asked: "Is this case related to sheepdogs?" ”

Lu Jinping thought for a while and said, "The three of you are the core of solving the case. I can tell you some of the discoveries, but be sure to keep the investigation a secret and never say anything about it. So as not to startle the snake, if the criminal learns about it, it will be troublesome to destroy the evidence of the crime. ”

Xiong Zhutou hurriedly said: "Of course, both of them have tight mouths, shouldn't there be any difference?" ”

Jiang Zhutou and Yao Zhutou hurriedly nodded.

Lu Jinping said: "Okay, then let me tell you, I found a small handful of hair in the mouth of the deceased." I tested it with a unique method and found that it was a large sheepdog. ”

All three were taken aback again. Xiong Zhutou said: "Can the lord tell what kind of beast is a handful of hair?" ”

"Hmm. As I said, I learned from a wandering monk how to solve crimes. This includes identifying what kind of animal the hair is. ”

The three catchers couldn't help but be dumbfounded, and praised each other one after another: "The lord's method of solving the case is really incredible, and it is extremely magical. ”

Lu Jinping said: "I tell you this to let you know that catching the person who raised the large sheepdog may be the key to solving the whole case." Therefore, I suspect that the owner of the dog is likely to be the murderer. ”

Yao Zhutou said: "I understand, don't worry, sir, even if I dig three feet into the ground, I have to find out this sheepdog, there are not many people who raise this kind of dog in our state, and I will definitely be able to find it." ”

Sure enough, the first breakthrough in this case started with the wolf dog.

Two days later, Yao Zhutou submitted a list to Lu Jinping, and there were three families in the entire city of Tongzhou that had large shepherd dogs. Only one family in the village outside the city has this type of sheepdog.

Lu Jinping immediately began to investigate. He took Xiong Zhutou and others to the first family in Tongzhou City to raise large sheepdogs. The sheepdog was tall and formidable, and looked a little scary, but it had been chained by its owner. The owner said that the dog was never let go, because it was too fierce and easy to hurt people, so it was raised in the yard.

Lu Jinping extracted the DNA swab of the wolf dog, and then immediately rushed to the second home.

The second sheepdog is a newborn cub the same size as a pet dog. I spent most of my time sleeping. Although it is very cute, Lu Jinping still did not let it go. DNA swabs were also extracted from it.

When he came to the third house, Lu Jinping found that the sheepdog of this family was a female, and the hair found in the deceased's mouth was a male sheepdog, which means that the possibility was directly ruled out.

Lu Jinping immediately returned home to test the swabs of the two sheepdogs.

The test results came out, and after comparing the hair DNA of the wolf dog extracted from the mouth of the deceased, it was found that the two sheepdogs did not match.

The last possibility was left to the shepherd dog family outside the city, of course, there is also a possibility that Yao Zhutou did not collect it all, and there may be other families who raised this kind of large dog, but they did not visit.

Lu Jinping rushed out of the city with Yao Zhutou and others, and he found that the village where Yao Zhutou said the sheepdog breeder was located was not far from the fire site, just on the back of the hill.

In front of the courtyard they came to, Yao Zhutou stepped forward and knocked on the door, and soon the courtyard door opened, and a young man with a high nose, deep eye sockets, and blond hair looked at them impatiently and said, "What are you doing?" ”

The last time Yao Zhutou asked Muramasa to bring it to find it, because Muramasa proved that their family had a large shepherd dog. But when the village was taking them to visit, the family didn't open the door and ignored them. Mura Zheng smiled bitterly and said to Yao Zhutou that this family is not a Tang Dynasty person, and their personality is very weird, so they don't provoke him easily, and they don't come and go, but their family does have a large shepherd dog, which is very fierce and half a person tall.

This time, Lu Jinping knocked on the door with a large group of arresters, accompanied by Muramasa, and the young man finally opened the door, but his face was very ugly, especially after seeing a large group of arresters.

Lu Jinping said: "We are from the Yamen, and we have a murder case to ask you about, can we go in?" ”

"Ask whatever you want, my father is sick, he doesn't want to see guests, what do you have to ask me." The man leaned against the doorrail, and did not mean to let Lu Jinping and them into the house.

Before Lu Jinping could speak, Xiong Zhu's head was already on fire. In ancient times, the investigation didn't talk about civilized law enforcement, so he directly stepped forward and grabbed the young man's neck, lifted him up and threw him into the snow under the steps, and said: "You kid speak politely, this is our lord, it's not your turn to set the score." Believe it or not, Lao Tzu beat you up and ask you again? ”

This time he threw the young man on his back. Quickly got up, with a frightened look on his face, but his mouth was still muttering: "If you have something to say, just ask." If you want to go in, you can go in, why do you start beating people......"

Xiong Zhutou kicked the door open, and then said to Lu Jinping: "Sir, please." ”

Lu Jinping stepped into the courtyard. I found that the yard was quite large and spacious, and it could be seen that the living standard of this family was still good, and there were also two servants in the yard, which looked similar to the young man who was opening the door. It seems that they are all people from the Tang Dynasty.

Lu Jinping said to the young man, "Where are you from?" What is your name? ”

The young man muttered and couldn't hear clearly. The bear hunted the bull's eyes, raised his fist with a mallet, and said, "The lord is good to ask you, if you don't answer." Then eat my fists and kicks first! ”

The young man shrank his neck and hurriedly said, "We are Turks, doing business in your Datang, what?" Wouldn't it be better for us to come? ”

Lu Jinping frowned and said, "I'll ask your name now!" ”

"My Turkic name is very long, and you can't understand it. I have a Han name, called Li Ping, you can call me by that name. ”

Lu Jinping nodded and said, "I heard that you have a sheepdog, where is that dog?" ”

"Gave it away."

"Oh, what a coincidence? Who did it give it to? ”

"To a friend, our Turkic one, he took it back to the steppe."

"When?"

"It was after the fire that day that the animal screamed and jumped, and the noisy man died of annoyance. I usually eat meat and I am very good. If you have to eat one or two catties a day, who can afford to raise them? Your Datang business is not easy to do, and I am too lazy to do it. I'm thinking about going back to the Turkic steppe to graze, send the dog away first, and we will go back to the Turks another day, and I won't look at your face in the Tang Dynasty. ”

Lu Jinping said: "Where does your dog live? What about his former nest? You can't even send the nest away, right? ”

The young man pointed to a wooden shed in the corner of the courtyard and said, "Where is it?" You're a few days late, I'll tear down the fire. ”

Lu Jinping didn't bother to pay attention to him, walked straight to the kennel, squatted down and took a look. It was found that a lot of hair had fallen out of the kennel, and there were a few pieces of bones that the dog had gnawed on. I can't help but light up my eyes. This thing should have dog saliva on it, and be able to extract DNA. So he picked up a few bones and put them in a paper bag. He put the fur in a paper bag, stood up, ignored the young man, and walked out the door.

When they all walked out of the courtyard gate, Li Ping slammed the courtyard door behind him, the sound was very loud, Yao Zhu's head changed color, and he was about to go back, but was stopped by Lu Jinping and said, "Forget it, don't be like them." Then he turned to the village who was following him and said, "Send someone to keep an eye on this family, don't tell them to leave, if they want to leave the village, immediately detain them, and at the same time come and report to me." ”

Muramasa hurriedly agreed.

Lu Jinping immediately returned to Tongzhou with his people and went straight home. still asked Ye Qingqing to be on guard at the door, and then he entered the house and closed the door, and tested the remaining bones that the dog had gnawed.

Soon the results were available, and the dog's DNA was detected on the bones extracted from the kennel, which was compared to the shepherd's hair DNA found in the deceased's mouth.

Lu Jinping's heart jumped suddenly, it turned out to be this Turk!

However, this alone cannot solve the case. Because DNA testing could not be used as evidence in ancient times, and at the same time, this test could not be directly concluded that it was done by the Turkic Li Ping. Because this can only prove one part of the whole event, not the killing itself.

Lu Jinping needs to find more evidence. He immediately organized a search of the house of the Turkic Li Ping.

When Li Ping and his family saw the big team of people surround their house, and Lu Jinping rushed in with people, the family was stunned. Li Ping's face changed, and he asked in horror: "You ......, what are you going to do?" ”

"We're going to search your home! Because I suspect you have something to do with a murder! ”

"Murder? I don't know what you're talking about! Li Ping glared and said, his wife ran out in a panic and took her husband's hand, "Husband, what's wrong?" ”

"It's fine. Don't worry, the yamen is probably mistaken, you hurry in and tell your father and mother not to worry. ”

"Oh, okay." The lady ran into the house in a panic.

"That's your wife?"

"So what?" Li Ping's tone was still very impulsive.

"If yes. Then tell her and all the people of your house to come into the courtyard, and we will search your house. If you dare to resist, you will be punished directly. Lu Jinping said tepidly and slowly.

The bear catcher next to him waved his hand: "Please come out of the inside!" ”

He followed Lu Jinping for a long time. I've also learned to speak politely. But those catchers didn't care about this, and rushed in directly and pulled the people inside out. Li Ping's father was sick and lay on the bed, so he didn't do anything to him, but he was also carried out with the bed and put in the yard.

Li Ping's family saw that Lu Jinping and them were like wolves and tigers, and the original fierceness was gone, so they could only cower and hide in the corner of the courtyard to watch.

Lu Jinping didn't let the catchers go in and search through the cabinets, that was not his style.

He took the forensic investigation box from Ye Qingqing beside him. He walked in and began to search one by one.

Because the cause of death of the deceased is currently a dagger pierced directly into the mouth. If the deceased was killed in this room, it would have left a blood stain. So, after entering the house. He took out his fluorescence-enhanced glasses and put them on, then used the ultraviolet laser forensic detector to begin scanning every corner of the house, especially some hidden places. If the crime scene is here, it must have been cleaned, and often hidden corners are not cleaned, and traces may be left.

When Lu Jinping searched a cellar behind Li Ping's bedroom where vegetables were stored, after being scanned by an ultraviolet laser forensic detector, he found a bloodstain in a corner of the cellar through fluorescence-enhanced glasses. This bloodstain cannot be detected with the naked eye. It's obviously been cleaned. But. It can't escape the detection of high-tech ultraviolet laser forensic detectors.

Lu Jinping was overjoyed and immediately extracted this bloodstain swab.

Next, Lu Jinping found a small amount of blood on the wooden planks of the carriage in the stable. Of course, it is also invisible to the naked eye, and it is discovered by the ultraviolet laser physical evidence detector. Extractions were also carried out.

He then searched the rest of the house, but found no other suspicious traces.

Lu Jinping came out after packing up his things and interrogated Li Ping again, the key was to inquire about the whereabouts of the shepherd dog. But no matter how Lu Jinping interrogated him, Li Ping always insisted that the sheepdog had been given to his fellow Turkic villagers. It has been brought to the Turks. I don't know where I went. and asked his wife, and his parents, and his servants. It is said that the shepherd dog belongs to Li Ping, and he gave it to someone, but they don't know the specifics.

Although two bloodstains were found, there is no DNA of the deceased as a comparison, so it is impossible to determine that these two bloodstains are the deceased, that is, there is no way to prove that the cellar is the scene of the murder, and that the car was transporting the body.

Lu Jinping decided to identify the two bloodstains first, on the one hand, to see if the two bloodstains were the same, and on the other hand, to see if they were left by Li Ping's family. So he took swabs from Li Ping and his family's intraoral mucosa. If the identification proves the same, then the case has taken a step forward.

Because the available evidence could not conclude that Li Ping or his family were criminals, Lu Jinping did not order the arrest, but only informed Li Ping that he could not leave Tongzhou, let alone return to the Turks, and at the same time sent Minzhuang and Arrest Kuai to conduct surveillance.

When Lu Jinping left here, he found that Li Ping's gaze at them was full of hostility. This made Lu Jinping very uncomfortable.

When Lu Jinping returned home, he immediately conducted a DNA test on the bloodstain samples taken from the cellar and carriage of the Turkic Li Ping's house, and found that it was human bloodstains, and the results of the sixteen STR classifications of the two were completely consistent, proving that they were bloodstains left by the same person.

Lu Jinping then tested the DNA swabs of Li Ping and his family, and confirmed that no one matched the bloodstains found in the cellar and on the canopy of the car, proving that the bloodstains in these two places were not left by Li Ping and his family.

This further increased the likelihood that Li Ping or his family would commit the crime.

Now, the key is that Lu Jinping needs the DNA of the deceased to be compared to determine whether the blood was left by the deceased. If the answer is yes, then the case can be said to be a foregone conclusion.

However, he found the problem difficult now.

The deceased had been incinerated at high temperatures, the muscle tissue was long gone, the hair was gone, and the bones found had been burned. The bone marrow inside is no longer able to extract DNA material for testing.

Lu Jinping re-observed all the bones of the deceased again, and indeed none or a single bone could have DNA substances, except for teeth.

The deceased's entire face was buried in the dirt, and his mouth was stuffed with mud and soaked in ice water, so that he survived the high-temperature barbecue, not only finding the dog's hair between the teeth, but also leaving the last possibility of extracting the deceased's DNA material. That's the teeth.

Teeth are the hardest thing in the human body, and when a person falls from a height of thousands of meters, his body may be shattered, but his teeth will not be broken in many cases. However, the teeth are too hard, and it is not easy to drill open the pulp inside the tooth to extract the inside for DNA testing, because now Lu Jinping is in the Tang Dynasty, and there is no special dental drill.

However, Lu Jinping still designed a special dental drill to try to drill teeth.

As he expected, the craftsmanship of the Tang Dynasty could not make a tooth drill that could drill open teeth, and many attempts failed.

Now, there is only one way to get the DNA of the deceased, and that is to find out the source of the body. By determining this, it is possible to find something that may have extracted DNA from the household items of the deceased's place of life, so that it can be compared and determined.

However, Jiang Zhutou, who was in charge of the source of the corpse, has not had any good news. On the contrary, it was the bear catcher who was in charge of finding the strangely shaped dagger that sent the news, but unfortunately it was the news that made Lu Jinping very disappointed. -- After Xiong Zhutou sent people to search for the blacksmiths and weapons shops related to the entire Tongzhou City, no one knew this strangely shaped dagger, did not know its origin, and did not know who its owner was.

Lu Jinping was dumbfounded, he asked Jiang Zhutou, who was responsible for finding the source of the body, but there was no progress, could it be that this case was going to become a headless case again? (To be continued)

PS: Work is busy, especially during this time. I wanted to increase the amount of updates, but I found that I still couldn't do it, so I still kept updating 5,000 words a day. Every day, 5,000 words are updated on time at 12 o'clock at noon.

The quantity of updates should serve the quality, especially the forensic detective mystery novels. Ensuring the quality of detection is king.

Thank you for your support. Thank you!
