Zhou Wang followed Lao Niu out of the office, and Wang Qin pushed Dalong: "Are you stupid?" If you don't follow the study at this time, when will you be able to become a teacher? ”

Only then did Dalong react and chased him out.

Wang Qin, Liu Bing and Xiao Shang went to find the three security guards who were already waiting in the team to make a record of the interrogation.

……

In the dissection room, three generations stood at the head of the little girl's corpse in dissecting gowns.

Lao Niu explained while operating:

"The child's scalp is incomplete, and it is very brittle, and there is no way to tell whether there is a hematoma under the scalp, but the skull fragmentation can be distinguished from the color of the brain tissue whether it is caused by trauma.

Zhou Wang said excitedly: "It's not a line, it's a depression!" ”

Lao Niu said: "This is a depressed fracture line, and there is bleeding in the brain tissue, and there is no bruise, so it is only caused by external force." ”

Dalong hurriedly asked: "Was the little girl knocked unconscious first and then burned to death?" ”

Lao Niu and Zhou Wang nodded at the same time.

……

Lao Niu finally got off work after working overtime.

Wang Qin and the others returned to their office, called Zhou Wang and Dalong, and several people partnered to order takeout.

When waiting for the takeaway, the comparison results came out, and the deceased was Lin Jiahe, Shi Yufen and Lin Duoduo's family of three.

Wang Qin said: "The security guard basically doesn't know anything, and when he goes to work, he is mainly lazy, and tomorrow we will first make the social relationship between the two clear, and if they can enter the house in the middle of the night, even the children will not be spared, it should be a vendetta." ”

Xiao Shang raised his hand and said:

"Raise an objection, the security measures in the villa area are not perfect, the fire burned the house very thoroughly, and many clues have been burned, and now we have no way to determine whether the murderer knocked on the door or pry the door and climbed the window to enter."

Dalong said: "I knew that the comparison results would come out at this time, what kind of takeout did you order, wouldn't it be delicious to eat at home?" I don't have any clues now, so don't we have to wait until tomorrow to investigate? ”

Zhou Wang said: "The deceased Lin family and a mold factory had a bad business during this time, owed some foreign debts, and had mood swings, but there were two cars parked in his garage, both of which were clean. ”

"What does that mean?" Dalong asked.

"At least it shows that the debt collector has not yet started his car, or that he has not yet been driven to the point of desperation, but you can focus on the debt dispute tomorrow, money is a thing, it is easy for people to lose their nature, if it is a debt with an institution, it is good to say, if it involves personal ......"

"So you thought it was a homicide and not an accident before the autopsy today?" Dalong asked.

"If you want to kill yourself, can you wake up in the morning and make a decision and do it at night? That must be a few days of contradictions, and in these few days, especially on the day of suicide, are you still in the mood to wash the car? Zhou Wang asked rhetorically.

Liu Bing snorted coldly, Wang Qin didn't wait for Liu Bing's mocking words to come out, and said first:

"If it were in the village, it was really hard to say where such a big fire would burn, but in a reinforced concrete house, it is difficult to achieve the murderer's purpose without relying on accelerants, I thought at first that the body was transferred, and the murderer deliberately burned the victim beyond recognition, and then I thought about how many years it was, and there would be no one who felt that they couldn't confirm the identity of the deceased if they couldn't see their faces clearly, right?"

"I understand what you mean, if it's just to kill these three people, there's no need to make such a big fire." Zhou Wang said.

"Yes, that's what it means! The Lin family and Shi Yufen are already dead, why do they still burn them? Or amplify the fire less, as if he was afraid of leaving some clues for the police. ”

Xiao Shang asked: "Could it be that you want to burn the traces you left behind?" ”

"It's possible, but he also needs to prepare in advance, let's take the accelerant as gasoline for the time being, there should be a report tomorrow explaining what the accelerant is, do you think the murderer didn't prepare gasoline in advance, and he didn't want to make it clear, this fire can burn?" Liu Bing asked?

Wang Qin said:

"That's what I'm talking about, he can't carry a gasoline drum to someone's door, right? Even if you climb the window and pry the door, it's not easy to carry a bucket of gasoline, and besides, you want to kill people...... Shi Yufen was strangled to death, Lin Jiahe was hit on the head with a blunt object, and the child, the child was also hit on the head......"

"Judging from the way the murder was committed, the murderer may have something to do with Shi Yufen." Zhou Wang interrupted Wang Qin and said.

At this time, the takeaway came, and Xiao Shang hurriedly said: "Eat, get off work after eating, what clues will you start tomorrow!" ”

"How much money do you make a month? If you have nothing to do, just order takeout and eat it at home, okay? The dragon muttered.

Liu Bing snatched Dalong's box of lunch: "Go home and eat!" I paid for the takeaway. ”

"Why?"

"It's up to you to grind and chirp! Can't order takeout after earning a lot? It's not your money to go home and eat and spend, it's also your parents' money, you gnaw on the old and you are very energetic, how old are you and you can't support yourself? ”

"What did I say? This is on the line! Whoever marries you in the future can suffer, a word is not to your liking, you can convict him of several civil and criminal crimes, you are not much better than domestic violence! Dalong snatched his lunch box and said excitedly.

Liu Bing tilted his head and looked at Zhou Wang, who hurriedly buried his head in eating wildly, as if he knew that Liu Bing remembered Lu Yi.

……

The next day, Zhou Wang arrived at the office a little late, he said that he had overslept, and Dalong said that he was tired these days, and people couldn't lack food or sleep.

Lao Niu was not in the office, saying that there was an injury appraisal to be done.

Dalong asked Zhou Wang: "Why would Niu Lao rather run these appraisals every day than participate in the homicide investigation?" When I first arrived, I thought I had to run for all the tests. ”

Zhou Wang said: "Didn't I tell you, Lao Niu wants to give young people a chance, not to have more contact with homicides, and to see more types of cases, just with the little knowledge you have learned, I really say that one day you will need to take the lead alone, and you are also cool." ”

Dalong nodded in agreement.

"You clean up, let's go to the scene of the crime again, call Xiao Chen, and ask him to bring the investigation box as well."

"What for?"

"There must have been some clues that were not found yesterday, so take advantage of the dawn and take a closer look."

"It's all burned to ashes, what can you find?"

"I'm most afraid of you when investigating cases! How do you know you won't find anything? The deceased died in bed and under the bed, were they moved after death or did they die there in the first place? What was the route of the murderer? Why did you beat the child, but not kill him? Did the blunt object that hit the Lin family and the head hit the little girl? ”

Dalong took a deep breath and asked, "Can these be seen at the scene?" Seeing that Zhou Wang was in a hurry, Dalong asked again: "Don't you have to tell Wang Qin and them?" ”

"They are mainly investigating the interpersonal relationships of the deceased today, and we are going to introduce the process of the deceased's death."

Zhou Wang said that he had already walked out of the office, and Dalong hurriedly followed.
