After whispering a few words to the police officers guarding outside, Wang Dong re-entered the house, at this time Xia Zhiqing and the others had already found Zhang Cuihua's body, her body fell to the ground, half of her body had been soaked in water too much, and the body of Zhang Cuihua's ten-year-old son was found in the corner of the West House, and the head was also smashed with a blunt object, and blood flowed all over the bed.

This scene is really tragic, even an old criminal policeman with many years of experience like Xia Zhiqing is not very suitable for this scene, so he first went outside to breathe fresh air before walking in again.

Lu Shanshan and Wang Dong didn't feel half uncomfortable, and even got together to judge how the deceased was killed by the murderer through the posture of the deceased falling.

The deceased on the ground should be Zhang Cuihua, the hostess of the house, and the reason why she said yes was because her face was hit by a blunt object, and her left eye and lower jaw were shattered.

"This should be Zhang Cuihua sleeping with her son in the East House, heard a movement in the West House, came out to check, but it happened that the murderer also happened to come here, after the two met, the murderer took a blunt object and gave Zhang Cuihua directly, I think the first blow should have hit Zhang Cuihua's jaw, so she couldn't make a sound to warn her son, and as a result, her son, like the man, was killed in his sleep."

Lu Shanshan nodded slowly, he also agreed with Wang Dong's idea, but the idea is the idea, and solving the case is to pay attention to clues, and now the ground is not dry, but it seems that it is undoubtedly very difficult to extract the murderer's footprints from the ground.

The more detailed search began again, Wang Dong opened the room from the house, and a fresh air mixed with the smell of earth poured in, which finally made him a little more comfortable, and first looked around the courtyard, but the two motorcycles in the corner of the place attracted his attention.

The motorcycle itself has nothing to pay attention to, but there is a white plastic pipe inserted in the fuel tank of the motorcycle, which makes Wang Dong a little puzzled.

This is all worth wondering, first use the camera to record these, just when Wang Dong was about to take a look at the white tube, suddenly a police officer walked in from outside the courtyard, saw Wang Dong and immediately shouted: "Wang Dong, Niu Er is back." ”

Niu Er came back, which was undoubtedly a big news in the village, and when Wang Dong squeezed out of the crowd, he saw a dark-faced man walking over surrounded by the police, shouting as he walked: "What are you doing here, and I didn't kill that woman, you can do whatever you want." ”

Although there were not many words, there was an extra layer of other meanings in Wang Dong's ears, he seemed to know that his mother-in-law Zhang Cuihua was good with others.

At this time, Niu Er finally came to Wang Dong's face, Wang Dongyi stretched out his hand and stopped the person, probably Wang Dong's face was still a little green, Niu Er was stunned for a moment, and didn't understand what this little policeman was doing when he stopped him.

Wang Dong opened the notebook and habitually asked, "Name?" ”

"Niu Xihong."

"Age?"

"37 years old."

"Occupation?"

"Labor." After speaking, Niu Xihong also gestured at his thick arm.

If it is a force, it seems that many things can be said clearly, such as the wire that binds the door, there are naturally more blunt objects on the construction site, and the most important thing is that this Niu Xihong has enough reasons to kill Zhang Cuihua and her adulterer, but if he is a murderer, why should he kill his son together?

For the time being, Niu Xihong was listed among the suspects, as for the male deceased, he still didn't let him meet now, and after saying a few words, Wang Dong asked the others to send Niu Xihong to the car first, and then return to the team together in a while, and then conduct a more detailed investigation.

There are many things going on indoors and outdoors, how did the murderer get into the yard? Whether or not you can find obvious footprints on the periphery has now become the focus of the work, Lu Shanshan led a new intern indoors, and the others began to look for possible doubts in the yard.

Thinking of this, Wang Dong thought of the motorcycle with the tube inserted again, and when he turned back, he happened to meet Xia Zhiqing who was also looking at the motorcycle and was stunned, Wang Dong walked over, carefully pulled the pipe up, put it under his nose and smelled it, the smell of gasoline is not very strong, it seems that this motorcycle has been parked here for a long time, and there is no gasoline for a long time.

"What does this tube do?" Xia Zhiqing asked curiously.

"I think someone tried to pump gas out of the tank, but it turned out that there was no gasoline in the tank for a long time, so they left this pipe here." Wang Dong guessed.

"Murderer?" Xia Zhiqing suddenly thought of yesterday's fire for no reason, maybe the murderer wanted to take gasoline out of the fuel tank at the beginning to light it, but the pipe was inserted, but he accidentally found that there was no oil in the tank, so he directly abandoned it.

It makes sense to say it, Wang Dong pondered for a while and nodded, then this pipe will become a treasure again, maybe it will be stained with the murderer's fingerprints and other things, take a big plastic bag to wrap the tube, and put it away.

There were not many other things in the courtyard that were worth noting, until half an hour later, when I finally found a trace on the courtyard wall, next to Niu's house, there were not obvious traces on a courtyard wall, as if it had climbed over the wall.

"Where is the owner of this house?" Xia Zhiqing found the village chief and pointed to the neighbors of the Niu family and asked.

"Oh, you're looking for Xiao Kai, this is my distant nephew's house, called Zhao Kai, I saw him just now, you wait, I'll find him for you right away." Zhao Danian quickly ran away, shouting Zhao Kai's name while running, and after a while, a middle-aged man in his thirties came out of the crowd, said a few words to Zhao Danian, and was brought to Xia Zhiqing.

"Hello, this is your house, right?" Xia Zhiqing asked, pointing to the house next door to the Niu family.

"Yes, yes, it's my house." Zhao Kai looked very ordinary, and smiled when he saw Xia Zhiqing, which made Wang Dong a little uncomfortable, and asked first: "Where were you from ten o'clock last night to one o'clock in the morning?" ”

"Uh......" Zhao Kai didn't have to think about it, and said directly: "I went to bed early last night, about eleven o'clock, and was woken up, and then I got up to fight the fire with them, and I didn't come back until about three o'clock." ”

Zhao Kai said reasonably, Wang Dong wrote down his words in the notebook, and then pointed to the wall and asked, "Then how should you explain it here?" ”
