The pattern that attracted Ling Xu's attention was a group of winding traces, this group of traces was very regular, and there was a thin silk thread in the center of the ashes, looking up along the thin line, I saw a burned switch at the upper end, and then up, there was a plug, it turned out that this was a burned electric blanket, commonly known as an electric mattress.

Because all the surroundings were burned black and scorched, so this group of traces was not noticeable, Ling Xu carefully observed, and found that the plug of the electric mattress was still plugged into the socket on the wall at this time, although the switch of the electric mattress was burned out, but if you carefully identify it, you can still see that the closer of the electric mattress is in a state of high gear at this moment.

When the firefighters were extinguishing the fire, they had already cut off the electric gate in the house, so Ling Xu was not worried about electric shock, and cleaned up the scorch marks on the closer with his hands, and then called He Siwen and asked him to send someone to re-shoot the scene near the corpse for evidence, focusing on the burned electric blanket.

"Alas...... The serious murderer is not caught, but he is messing around here, and the people from the technical department have just finished collecting evidence, what else is there to take pictures of? Although he muttered in his heart and disagreed with Ling Xu's approach, He Siwen did not say it explicitly, but according to his order, he found someone from the technical department to re-inspect the scene and take photos for evidence.

Leaving the house, Ling Xu came to the courtyard, took off his gloves, washed his hands with water, and then splashed the water in the basin casually, as a result, just as Ling Xu was about to turn around, he suddenly saw an interesting phenomenon.

It turned out that when Ling Xu splashed the water just now, he happened to splash the water in the basin to the corner next to the faucet, and that place was the place where Bai Yuanchao raised his dogs, and next to the kennel built up, there was a broken bowl, which seemed to be fed to the dogs, and many of the water that Ling Xu spilled fell into the bowl, and at this moment, the little stupid dog that Bai Yuanchao was feeding couldn't wait to lick and drink from the bowl.

Looking at the water in the bowl was drunk by the dog in the blink of an eye, Ling Xu retook some water with a basin, and after pouring the water into the bowl, he stood there quietly watching the dog drink water, when the dog drank the water in the bowl, he continued to add water to the bowl, and added four bowls of water in a row before the dog stopped drinking water.

"Captain He, please go to the house next door and get a few steamed buns."

A few minutes later, He Siwen found a bag of steamed buns and stuffed them directly into Ling Xu's hand, the dog saw the steamed buns in Ling Xu's hand, and was so anxious that he almost stood up, if it wasn't tied by an iron chain, it was estimated that he would have fallen on Ling Xu at this moment.

Seeing that the dog was so impatient, Ling Xu took the steamed buns that He Siwen found, and fed them to the dog piece by piece, one, two, three, four, five, enough to eat five steamed buns, and the dog filled his stomach, when Ling Xu saw the dog put the sixth steamed bun he threw into the nest for storage, he knew that the dog had eaten enough.

Returning the pocket in his hand to He Siwen, Ling Xu showed a thoughtful expression on his face, took the pocket handed over by Ling Xu, and saw that only half of the steamed buns in it were left, He Siwen said casually: "I'm ...... This dog hasn't eaten for a few days, how can he be hungry like this. ”

Ignoring He Siwen's words, Ling Xu's dog came in front of him, probably because Ling Xu had just fed steamed buns and water, after the dog saw Ling Xu, he wagged his tail, snorted lightly, and did not roar.

Then, Ling Xu asked He Siwen and several members of the criminal police team to take turns to get together, but when the dog saw everyone, it kept barking loudly, roaring and rushing forward, it seemed that it wanted to drive those strangers out of the house.

After the people of the criminal police team dodged away, Ling Xu invited a few nearby neighbors and asked them to get together in front of the dog, it is strange to say, after the dog saw those villagers, he honestly lay on the ground, with a docile look, it seems that this dog has a relatively stable personality when he meets familiar people.

After observing these, Ling Xu asked He Siwen to send someone to visit the village and ask the nearby villagers about a few things, first, to ask everyone if they had noticed any abnormalities in Bai Yuanchao's house recently? Second, when was the last time the villagers saw Bai Yuanchao? Third, in the past few days, have any strangers been in and out of Bai Yuanchao's home?

He Siwen did not arrange for someone to carry out Ling Xu's order, but raised objections, he believed that the criminal police team should indeed conduct a visit and find the platoon, but the focus of the criminal police team's visit and platoon should be on investigating the arson suspect, and after finding the arsonist, lock up the suspect in Shunteng.

If the police force is now put on investigating the abnormality of Bai Yuanchao's home and Bai Yuanchao's life actions within a few days, it is a waste of police force and a consumption of the golden period for solving the case, and the fire broke out in the early hours of this morning, then the focus of the investigation should be mainly this morning.

He Siwen believes that the first task now is to check the monitoring of nearby intersections, and investigate the suspicious people and vehicles who have entered and exited Baijia Village in the early hours of this morning, focusing on suspicious vehicles.

In this case, the murderer needs to drive a car with a large interior space, and the ideal model is a van, so He Siwen wants to arrange his subordinates to divide into two roads, one to investigate the surveillance cameras along the way, and the other to be responsible for detecting vans or suspicious vehicles entering and leaving the village. As long as you find the car, you can lock the murderer.

Seeing that He Siwen was unwilling to carry out his orders, Ling Xu was more or less helpless, although he had the right to solve the case, but if He Siwen did not cooperate with him, Ling Xu would not be able to act according to his own thoughts even if he had thoughts in his heart.

After a moment of silence, Ling Xu proposed to make a bet with He Siwen, Ling Xu asked He Siwen to leave two members of the criminal police team to assist him, and after that, Ling Xu and He Siwen acted at the same time according to their own ideas, and the two teams competed to see who found the suspect first.

Originally, He Siwen was dissatisfied with the direction of Ling Xu's investigation, thinking that Ling Xu's various actions were a waste of time and a waste of police power, so after hearing Ling Xu's proposal for the competition, He Siwen did not hesitate at all, and immediately agreed.

Assigned two people to cooperate with Ling Xu, He Siwen took out the walkie-talkie and gave a task to the team, he first arranged for the technical department to extract fingerprints from the scene, and then instructed the people of the criminal police team to go to the nearby intersection to investigate and monitor, check the suspicious vehicles and pedestrians entering and leaving the village, focusing on the vehicles entering and leaving the village after six o'clock in the morning today.

Considering that after the murderer stole those household appliances, the possibility of using them by himself was relatively small, so He Siwen sent people to the nearby second-hand household appliances recycling market to take a turn, and after arranging these, He Siwen thought about it, and sent some people to visit the villagers to see if Bai Yuanchao had any conflicts and disputes with others before his death.

When He Siwen was busy here, Ling Xu looked at the two people around him and had a brief exchange, Ling Xu had some understanding between the three of them, the two team members sent by He Siwen to Ling Xu were named Du Zhou and Pang Licheng, Pang Licheng is 43 years old this year, Du Zhou is younger, only 38 years old this year.

After introducing each other, Ling Xu didn't have too many greetings, and directly assigned the work, he asked Du Zhou to go to the village to inquire about it and see if anyone met several criteria, first, to know the deceased. Second, be in good shape. Third, there is a lot of strength. Fourth, have experience in home appliance maintenance. Fifth, be bold. Fifth, the family background is not very good. Sixth, they have a history of theft or sale of stolen goods. Seventh, there is an urgent need for money in the near future.

In addition to these points, Ling Xu also asked Du Zhoushun to inquire about it, and asked the villagers if they had noticed anything unusual in Bai Yuanchao's house recently? When was the last time the villagers saw Bai Yuanchao? Has there ever been a stranger in or out of Bai Yuanchao's residence?

When Du Zhou went to work according to Ling Xu's order, Ling Xu called Pang Licheng to his side again and instructed him: "Brother Pang, you go to the fire brigade and ask them to send someone over to identify the cause of the fire, and in addition, please ask a senior forensic doctor to come over and check the time of death of the deceased." ”

After Ling Xu finished his order, Pang Licheng did not hesitate, and immediately drove towards the county fire brigade.

Ling Xu is different from He Siwen, He Siwen focused his investigation on the moment when the fire broke out in the early hours of this morning, but Ling Xu set the time of the investigation two days ago because of the state of the dog when he ate water and steamed buns.

When He Siwen learned about Ling Xu's investigation direction, he couldn't help but shake his head with some contempt, and said to himself with a smile: "It's nonsense, the fire didn't happen two days ago, what was there to investigate at that time?"

Also, this person actually went to the forensic doctor to investigate the time of death of the deceased, the deceased obviously died of a fire in the early hours of this morning, what is there to investigate, he doesn't even know this basic common sense, and he is still a policeman. ”

Although he knew that He Siwen had opinions about his own approach, he didn't defend anything, since Liu Qianchuan led him to see Ren Daojian, Ling Xu got rid of the problem of "everything is preconceived", and tried to make himself "always in detail." ”

Ten minutes later, three staff members of the county fire brigade rushed to the scene of the fire, said hello to Ling Xu and He Siwen, and then entered the scene to investigate the cause of the fire.

After more than ten minutes, Pang Licheng led a man who was polite, about 40 years old, capable-looking, wearing a police uniform and a second-class police inspector's epaulette, to the scene of the crime.

Seeing this person, He Siwen took the initiative to greet him: "Section Chief Li, why are you here in person?" ”

It turned out that this person was Li Youjie, the section chief of the Forensic Medicine Department of the Beiyu County Public Security Bureau, and exchanged a few words of greeting with He Siwen, and Li Youjie said hello to Ling Xu under He Siwen's introduction.

After learning of Li Youjie's identity, Ling Xu first thanked Li Youjie for coming, and then asked him to inspect some of the deceased's bodies, but Ling Xu told Li Youjie about the deceased's daughter's objection to the autopsy, hoping that Li Youjie could conduct the autopsy without destroying the body.

Although Ling Xu's requirements were a bit high, Li Youjie pondered for a while, then nodded, and after putting on gloves and masks for himself, Li Youjie looked around and asked for an assistant to help him perform the autopsy.

Hearing this, Pang Licheng coughed twice and quietly took two steps back. He Siwen also pretended not to hear, holding his leather bag and bowing his head from the spot to think about something. Several members of the surrounding criminal police team also turned their heads to the side with blank expressions, as if there was some treasure somewhere.

Originally, after Ling Xu heard that Li Youjie needed an assistant, he also planned to play some tricks, but he was a step slower, and just as he was about to act, others had already used all the moves he wanted.

Seeing everyone's expressions in his eyes, Ling Xu was a little speechless while being annoyed, found a pair of gloves and a mask to put on, and then said with a depressed face that he could be Li Youjie's assistant.

When the words fell, Li Youjie urged Ling Xu to enter the scene for an autopsy from behind......
