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

Captain Jiang laughed dryly and said, "Sir, this corpse has been burned to carbon and has no appearance. How can I find it?"

"Indeed, the appearance of the deceased cannot be restored, but there is roughly a age limit and there is a rough time to die. So, what you want to visit is the young woman who disappeared during this period, and the deceased is ten miles away from Tongzhou Prefecture. It should be centered around. On the one hand, it is people in the city, and on the other hand, people in the surrounding villages outside the city, so you must find out clearly. The work you have to do is to collect all the list of these missing persons for me, so that there is no omission. This work is also very important. Finding the source of the corpse is often the key to solving the case."

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

Lu Jinping looked at Captain Yao and said, "You are responsible for spreading around the fire scene to find nearby sheepdogs and large sheepdogs to see who owns such dogs. You need to list all the lists, including the basic situation of this family, etc."

When the three of them heard that Lu Jinping actually asked Captain Yao to look for the sheepdog, they did not understand Lu Jinping's intention for a while. Captain Yao said, "Sheepdogs are usually used on the grassland, and few people in the city have such dogs."

Lu Jinping said: "This is the key. The fewer people raise this kind of dog, the higher our chances of solving the case."

Captain Yao asked: "Is this case related to a shepherd dog?"

Lu Jinping thought for a while and said, "You three are the core of solving the case. I can tell you some of the discoveries, but be sure to strictly observe the secret of investigation and never tell them at will, so as not to alert the enemy. If the criminals learn about it, it will be troublesome."

The captain Xiong hurriedly said, "This is of course. Both of them have tight mouths, so there should be no mistakes?"

Captain Jiang and Captain Yao nodded quickly.

Lu Jinping said: "Okay, then I will tell you that I found a small chunk of hair in the mouth of the deceased. I used a unique method to test it. It was found that it was a large shepherd."

The three of them were shocked again. The captain bear said, "Can you tell what kind of wild beast a tuft of hair is?"

"Well, I said that I learned the method of solving cases with a traveling monk, including identifying what kind of animal hair is."

The three captains couldn't help but be dumbfounded and exclaimed repeatedly: "The Lord's method of solving cases is really incredible and magical."

Lu Jinping said: "I tell you this to let you know that catching people raising large sheepdogs may be the key to solving the entire case, so I have to spare no effort to investigate. I suspect that the owner of the dog is likely to be the murderer."

Captain Yao said, "I understand. Don't worry, even if I dig three feet into the ground, I will find this sheepdog. There are not many people who raise such dogs in our Tongzhou, so I will definitely find them."

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

Two days later, Captain Yao submitted a list to Lu Jinping, where three families in Tongzhou had large sheepdogs. Only one household in the village outside the city had such sheepdogs.

Lu Jinping immediately began to investigate. He brought Bear Captain and others to the first family to raise large sheepdogs in Tongzhou City. The sheepdog was very tall and mighty, and looked a little scary, but it was tied up by the owner with iron chains. The owner said that the dog had never been spared because it was too ferocious and could easily hurt people, so it was kept in the yard.

Lu Jinping took out the DNA swab of the wolf dog and rushed to the second house immediately.

The second sheepdog was the newly born Xiaozaizai, the same size as a pet dog, and spent most of the time sleeping. Although it was very cute, Lu Jinping still didn't let it go and also extracted its DNA swab.

When he arrived at the third house, Lu Jinping found that the sheepdog in this house was a female. The hair found in the mouth of the deceased was a male sheepdog, which means that the possibility was directly ruled out.

Lu Jinping immediately returned home and tested the swabs of the two shepherds.

After the test results were found, the hair DNA of the wolf dog extracted from the mouth of the deceased was compared. It was found that the sheepdogs in both families did not match.

The final possibility was left to the shepherd family outside the city. Of course, there is another possibility that Captain Yao did not collect all of them. Others may have raised such large dogs, but they did not visit them.

Lu Jinping led Captain Yao and others to the outside of the city. He found that the village where Captain Yao said the shepherd dog was raised was not far from the fire site, just on the back of the hill.

In front of the courtyard where they came, Captain Yao stepped forward and slapped the door. Soon the gate opened. A young man with a high nose bridge, deep eye socket and blonde hair looked at them impatiently and said, "What are you doing?"

The last time Captain Yao asked Cun Zheng to bring him, because the village proved that they had a large shepherd dog. However, when the village brought them to visit, the family did not open the door and ignored it. Cun Zheng smiled bitterly and said to Cun Yao that this family was not from the Tang Dynasty and had a weird personality, so they did not provoke him or interact with each other easily. However, their family did have a large shepherd dog, which was very fierce and half a person tall.

This time, Lu Jinping brought a large group of constables to knock on the door accompanied by the village chief. The young man opened the door at least, but his face looked very bad, especially after seeing a large group of constables.

Lu Jinping said: "We are from the yamen. There is a murder case to ask you. Can we go in?"

"If you want to ask, ask what you want. My father is sick and he doesn't want to see guests. Ask me if you have anything to do." The man leaned against the door railing and did not mean to let Lu Jinping and the others enter the house.

Before Lu Jinping could speak, Captain Bear was already in a state of fire. In ancient times, he did not talk about civilized law enforcement. He went forward and grabbed the young man's neck and lifted him up and threw him into the snow under the steps, saying, "You guys are kind-hearted. This is our Lord, it's not your turn to show off. Believe it or not, I beat you up and ask you again?"

This made the young man fall and he quickly get up. He showed a look of fear on his face, but his mouth mutters: "If you have something to do, ask if you want to go in, why do you hit someone..."

Captain Bear kicked the door open with a slam, and then said to Lu Jinping: "Sir, please, please."

Lu Jinping stepped into the yard and found that the yard was quite large and spacious. It can be seen that the living standards of this family are quite good, and there are two servants in the yard. Judging from the appearance, they are almost the same as the young people who are opening the door. They seem to be from the Middle Earth people of the Tang Dynasty.

Lu Jinping said to the young man: "Where are you from? What's your name?"

The young man couldn't hear clearly the muttering words. The captain bear glared at the eyes of the bull, raised his big fist and said, "Sir, I'm so sorry, if you don't have a good answer, then I'll take a meal first!"

The young man said, shrank his neck and said quickly, "We are Turkic. What's the matter in your Tang Dynasty? Could it be that we won't come?"

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

"My Turkic name is very long, and you can't understand it even if you say it. I have a Han name called Li Ping. Just call me this name."

Lu Jinping nodded and said, "I heard that you have a shepherd dog. Where is that dog?"

"I've given it to someone."

"Oh, such a coincidence? Who did you give it to?"

"I gave it to a friend, we Turkic, and he took it back to the grassland."

"When did it happen?"

"It was after the fire that day, the beast yelled and jumped, which made people very annoyed. I usually eat meat so well, and I have to eat one or two pounds a day. Who can afford it? Your business in the Tang Dynasty is not easy to do, and I am too lazy to do it. I was thinking about going back to the Turkic grassland to graze, and sending the dog away first. We will also go back to the Turkic next day. We will not look at your face in your Tang Dynasty."

Lu Jinping said: "Where is your dog living? Where is his former nest? It is impossible for him to even send the nest away, right?"

The young man pointed to a wooden shed in the corner of the yard and said, "Where are you there? I'll demolish it a few days later. I'll burn it."

Lu Jinping was too lazy to pay attention to him, so he walked straight to the doghouse, squatted down and looked at it, and found that there were a lot of hair falling from the doghouse, and there were still a few pieces of bones left by the dog, and his eyes lit up. There should be dog saliva on this thing, which could be extracted into DNA. So he picked up a few bones and placed them in a paper bag. He also put the dog hair in the paper bag, stood up, ignored the young man, and walked out of the door.

When they all walked out of the yard, Li Ping closed the yard with a bang from behind. The sound was very loud. Captain Yao changed color and wanted to go back, but was stopped by Lu Jinping and said, "Forget it. Don't be as knowledgeable as them." He turned around and said to the follower of Kuang Zheng: "Send someone to stare at this family, don't tell them to leave. If they want to leave the village, take them off immediately and report to me quickly."

The village quickly agreed.

Lu Jinping immediately returned to Tongzhou and went straight back to his home. He still asked Ye Qingqing to guard the door, then went into the house and closed the door, and tested the remaining bones of the extracted dog.

The results were soon obtained. The dog's DNA was detected on the bones extracted from the dog's kennel. After comparison, it was completely consistent with the shepherd's hair DNA found in the mouth of the deceased.

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

However, this alone cannot be solved. Because DNA testing could not be used as evidence in ancient times, and at the same time, this testing could not be directly concluded that it was done by the Turkic Li Ping and others. Because this can only prove one of the fragments of the entire incident, but cannot prove the murder itself.

Lu Jinping needed to find more evidence. He immediately organized a search for the Turkic Li Ping's house.

When Li Ping and his family saw the brigade constable and Min Zhuang surrounding their family and Lu Jinping rushed in, the family was shocked. 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're related to a murder!"

"Murder? I don't know what you said!" Li Ping said as he stared at him. His wife ran out in panic and held her husband's hand, "Husband, what's wrong?"

"It's okay. Don't worry, the yamen probably made a mistake. Go in and tell your parents not to worry."

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

"Is that your wife?"

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

"If so, then ask her and all the people in your family to come to the yard. We want to search your home. If you dare to resist, just take the punishment." Lu Jinping said slowly without any hesitation.

The head bear next to him waved his hand: "Please come out all the people inside!"

After following Lu Jinping for a long time, he learned to be more polite. However, the constables ignored this and rushed in and drove out the people inside. Li Ping's father was lying on the bed and did not move him. However, he was carried out with the bed and placed in the yard.

When Li Ping and his family saw Lu Jinping and others as good as wolves and tigers, their original ferocity disappeared, so they could only shrink and hide in a corner of the yard to watch.

Lu Jinping did not let the constables go in and search through the cabinets. That was not his style.

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

Because the cause of death of the deceased is that the dagger is directly stabbing into the mouth and piercing the brain and dying. If the deceased was killed in this room, it may leave blood. So, after entering the room, he took out the fluorescent enhancement glasses and put them on, and then used an ultraviolet laser evidence detector to scan every corner of the house, especially some hidden places. If the crime scene is here, it must have been cleaned, and often the hidden corners are not cleaned, leaving traces.

When Lu Jinping searched for a cellar storing vegetables behind Li Ping's bedroom, he scanned the ultraviolet laser evidence detector and found a blood spot in a corner of the cellar through fluorescence enhancement glasses. This blood spot cannot be found with the naked eye. It is obvious that it has been cleaned. However, it cannot escape the detection of the high-tech ultraviolet laser evidence detector.

Lu Jinping was delighted and immediately extracted the blood-stained swab.

Next, Lu Jinping found a small amount of blood on the wooden boards laid in the carriage carriage in the stable. Of course, it was not visible to the naked eye. It was discovered by ultraviolet laser physical evidence detectors. It was also extracted.

After searching for other parts of the entire courtyard, he found no other suspicious traces.

After Lu Jinping packed up his things, he came out and interrogated Li Ping again. The key was to ask about the whereabouts of the sheepdog. However, no matter how Lu Jinping interrogated, Li Ping always insisted that the sheepdog had been given to his fellow Turks and had been taken to the Turks. He didn't know where he went. When asked about his wife, parents, and servants, they all said that the sheepdog was from Li Ping and he gave it to someone. They didn't know about it.

Although two blood stains were found, there was no DNA of the deceased as a comparison object, so it was impossible to confirm that these two blood stains were the deceased. In other words, there was no way to prove that the cellar was the murder scene, and that car transported the corpse.

Lu Jinping decided to identify the two blood stains first, on the one hand, to see if the two blood stains are the same, and on the other hand, to see if they were left by Li Ping's family. So he extracted the oral mucosal swabs of Li Ping and his family. If the identification proves that they are the same, then the case will move forward one step forward.

Because the existing evidence cannot conclude that Li Ping or his family are criminals, Lu Jinping did not order the arrest of people, but only informed Li Ping that he could not leave Tongzhou and could not return to the Turks. At the same time, he sent civilians and constables to monitor him.

When Lu Jinping left here, he found that Li Ping's eyes were full of hostility when he looked at them. This made Lu Jinping very uncomfortable.

When Lu Jinping returned home, he immediately conducted DNA testing on the cellar of the Turkic Li Ping's house and the blood stains extracted from the carriage. He found that it was human blood stains, and the results of the sixteen str typing of the two were completely consistent, proving that they were blood stains left by the same person.

Then, Lu Jinping tested Li Ping and his family's DNA swabs and confirmed that no one matched the blood stains found in the cellar and on the tent, proving that the blood stains in these two places were not left by Li Ping and his family.

This further increased the possibility of Li Ping or his family committing crimes.

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

However, he found that this problem was difficult now.

The deceased had been burned by high temperature and was highly carbonized. The muscle tissue had long disappeared, the hair was gone, and the bones found were burned. The bone marrow inside could no longer be extracted for testing.

Lu Jinping once again observed all the bones of the deceased. There was indeed no piece or bone that could have DNA substances except teeth.

The entire face of the deceased was buried in the soil, and his mouth was filled with mud and soaked in ice water. This allowed him to survive the high temperature barbecue. Not only did the dog's hair be found in the gaps in the teeth, but the final possibility of extracting the deceased's DNA substance was left. That was the teeth.

Teeth is the hardest thing on a human body. When a person falls from thousands of meters above the altitude, his body may fall into pieces, but in many cases, human teeth will not be broken. However, the teeth are too hard, and it is not easy to drill open the teeth and extract the pulp inside for DNA testing, because Lu Jinping is now in the Tang Dynasty and does not have a special tooth drill.

However, Lu Jinping designed a special tooth drill to try to drill open teeth.

As he expected, the Tang Dynasty's craftsmanship could not create a tooth drill that could drill teeth, and many attempts failed.

Now, there is only one way to get the DNA of the deceased, that is, to find out the source of the corpse. By determining this, you can find the things that may extract DNA from the daily necessities of the deceased's living places, so that you can compare and determine.

However, Captain Jiang, who was responsible for the source of the corpse, had not yet received good news. Instead, Captain Bear, who was responsible for finding the strange-shaped dagger, had news. Unfortunately, it was a news that disappointed Lu Jinping. Captain Bear sent people to search for the blacksmiths in Tongzhou City. After the weapon shop, no one knew the strange-shaped dagger, he didn't know where it came from, and he didn't know who its owner was.

Lu Jinping was stunned. He asked Captain Jiang, who was responsible for finding the source of the corpse, but there was no progress. Could this case be a headless case again? (To be continued.)

ps: I am very busy at work, especially during this period. I wanted to increase the amount of updates, but I found that I still couldn't get enough, so I should keep updating for 5,000 words every day. I updated five,000 words every day, and updated on time at 12 noon.

Updated quantity must serve the quality, especially forensic detective mystery novels. Ensuring the quality of the detection is the king.
