Xiao Chen did not go to the scene of the crime with Zhou Wang, because he was already at the scene of the crime.

Zhou Wang saw several trace inspectors squatting on the ground in the villa, carefully peeling off something, and said to Dalong: "Look at people!" It must be that you have encountered a question at work, and people know to come to the scene to find answers, what about you? I knew that I would stare at my eyes and ask, 'What are you doing?' ’”

"I went back last night and thought about it for a long time, and there were a lot of things I couldn't figure out at that time, so I wanted to come to the scene of the crime to see, thinking about it, I don't necessarily have to say it." Dalong quibbled.

"Tell me, what do you can't figure out?"

Zhou Wang said as he walked towards the bedroom on the first floor.

"Didn't you say something just now, I didn't think so comprehensively, I thought about the murderer's modus operandi, last night you said that the murderer may have something to do with Shi Yufen, I think, it depends on how many people committed the murder, if it is not one person, it is difficult to say, but no matter whether it is a person or several people, there must always be a step, because with the accelerant wants to burn, it is premeditated, the wound of the deceased Lin Jiahe is basically in the occipital position of the back of the head, which means that the murderer was behind Lin Jiahe when he committed the murder, and the deceased Shi Yufen died in the bedroom bed, And he died first, Shi Yufen exclaimed, Lin Jiahe was on the first floor at the time, he wanted to rush up, but someone stopped him......"

"Are you assuming there are two or more murderers?" Zhou Wang asked.

"Yes, I think it's hard to do this alone, you think, it's impossible for the murderer to come in with an oil drum, so why don't you call the police? Even if Lin Jiahe opened the door and only one person came in, in the dead of night, two people hit one, there is always one person who can call the police, what is the murderer premeditating? Isn't it easy to premeditate yourself? Only two or more murderers shot at the same time to kill both upstairs and downstairs, and no one could call for help, and the child, who was woken up because he heard the movement, came out of the bedroom door, was shot in the head by one of the murderers, and then carried back to the bed, and then set fire. ”

Zhou Wang stood at the door of the bedroom, glanced at the staircase and said, "If the murderer is two people, why can the Lin family tolerate someone going upstairs in the middle of the night?" ”

"Lin Jiahe is under control."

"Instead of yelling for his wife and children to lock the door, he was honestly controlled, and saw someone go upstairs, and upstairs were his wife and daughter!"

"That is, a murderer knocked Lin Jiahe unconscious with a blunt object as soon as he came up, and a murderer went upstairs directly to ......"

"Why did they come in in the middle of the night? I mean, those who can come in must have enmity, why did the Lin family let people in, instead of going out to interview the people themselves? ”

As soon as Zhou Wang's voice fell, the phone rang, it was Wang Qin.

"The fire identification report came out, the accelerant was gasoline, the three bedrooms, the beds were poured with gasoline all around, and the study and living room, not anywhere else."

"Dalong and I are in the villa to see if we can deduce the true purpose of the murderer through the cause of the deceased's death."

"We are investigating the social relations of the deceased, that Shi Yufen, alas, the social relations are too complicated! That's it, I can still marry home, I'm also convinced, let's meet in the afternoon. ”

The two hung up the phone, and Dalong hurriedly asked, "Do you think the murderer's purpose is not just to kill anyone?" ”

"Wang Qin said that the fire identification report came out, the accelerant was gasoline, in addition to the bedroom, it was also splashed in the study and living room, you said that if the murderer only wanted to kill people, and then destroy the traces of his own visit, is it necessary to even light the study that he has not been to?"

"So the murderer went to the study! Isn't this the place where there is no silver? ”

"Some criminals like to be self-righteous, and this can't be blamed on them, if their brains are good, they won't be mixed up to the point of killing people! You go talk to Xiao Chen and check the study more. ”

"Why are you going?"

"I'll take a look around the villa."

There are small yards in front and back of the villa, the fire did not burn into the front and rear yards, the fire grass on the wall in the courtyard is still standing, and some are trampled down, and when the fire is extinguished, he also helps the murderer to wash away the traces that may be left in the yard, or, the murderer did not leave traces in the courtyard at all, Zhou Wang didn't believe that the murderer even thought of what the fire would do in advance.

The villas on both sides of this villa are empty, one is sold and no one lives, and the other has not been sold, Zhou Wang turned around, stood at the main entrance again, he looked at the warehouse next to him, frowned, and walked in.

Dalong came out to look around and found Zhou Wang in the garage, who was in a daze with the tools on the garage wall.

"You don't think the murderer is looking for a murder weapon here, do you?" Dalong asked.

"Let's go to the second floor." Zhou Wang turned around and walked out of the garage.

"Master, to be honest, I can't keep up with your train of thought, what do you mean by a hammer in the east and a mallet in the west?" Dalong asked as he walked.

Zhou Wang didn't speak, went up to the second floor, he first looked at the child's bedroom, this bedroom and the master bedroom are diagonally opposite, as long as the movement in the master bedroom is not particularly big, it is difficult to wake up the sleeping child, but the child's injury is on the top of the head, that is to say, when the child is attacked, it should be standing, what woke the child up? When Shi Yufen was pressed down on the bed, she shouted?

Zhou Wang went to the master bedroom again, and the charred bed drew the position where the body was found, not lying on the bed where it should be lying, but horizontally on the bed, the charred body shrunk, and the deceased's feet were not outside the bed, but completely on the bed.

Zhou Wang frowned.

At this time, Xiao Chen stood at the door of the study on the first floor and shouted, "Old Zhou, there is something wrong with the study. ”

Zhou Wang hurriedly went downstairs.

Xiao Chen stood at the door of the study, pointed to the black mud on the ground in the study, and said:

"When the fire extinguishes the fire, a water flow is formed in the room, which has a certain effect of scouring, which affects the original state after burning, but if the books are in the bookcase, after the burning, the ash pile should be formed on the side of the wall, even if there is a fire water gun, there must be a place where the water can not be sprayed, that is, there is a place that is not impacted by the water flow, and the original state is maintained, however, we found the corners and corners that have not been burned in the ground ash pile in many places in the study, you pay attention, the bookcase is not all solid wood, there are iron shelves, and the bookcase is not poured. The glass shattered to the ground......"

"You mean, the bookcase didn't fall over, but you found a book that wasn't completely burned at a distance from the bookcase?" Zhou Wang asked.

"Yes, this room is said to be a study, just such a bookcase, and then a large desk, and there is a large cabinet with some ornaments, which can be burned to ashes is the book, it stands to reason that the corners of those books that have not been completely burned have been washed away to other places, I can understand, but everywhere, especially the glass of this cabinet containing the ornaments is also broken, and there are some corners and corners of books that have not been burned out under the glass......"

"Could it be that the glass burst after the bookcase burned...... I can't bring a few copies of that. Dalong asked and answered himself.

Zhou Wang said: "Collect evidence first, it is very likely that the murderer went to the study to find something and threw the book on the ground." ”

Xiao Chen said: "I think so too. ”

"When you're done here, you go to the garage and take a look, I always feel that something is wrong with the garage." Zhou Wang said.

Xiao Chen nodded and entered the study.
