Wang Qin rubbed his face and said a little discouraged: "I feel that I have been busy all morning, and there is no clue they are looking for." ”

Xiao Shang persuaded:

"What credit did you take with Zhou Shentong? He is the best in forensic medicine, and the best in forensic science among investigators, he thinks about the case for 25 hours a day 24 hours a day, what do you compare with him? One day he couldn't think of a reason, which was the loss of our serious crime team! ”

Liu Bing held his chin and asked, "Eh, you say, is it possible that it is because of Lao Zhou that Feng Ju is reluctant to add people to us?" I remember that Bureau Feng said that one Zhou Wang can top three old investigators. ”

"It depends on how old you are!" Wang Qin raised his spirit: "Let's get the deceased's car in order now!" ”

……

Zhou Wang took Dalong to put on the autopsy suit again, Zhou Wang has been blaming himself, he felt that the previous autopsy missed a very important link, it was his negligence, repeated a few times, Dalong couldn't listen to it anymore, and asked:

"Did you delay something? If you find a timely remedy, how many times do you chatter, and the autopsy report will be automatically generated? It's not that I said you, Master, you're a little too strict with yourself......"

"I'm not strict with myself, and if I did, I wouldn't have made this mistake......"

"When I didn't say it, let's get to work!"

The second autopsy did not waste too much time, because the purpose was single, the deceased Shi Yufen had sex before his death, and there were still biological samples left in his body!

When Dalong excitedly took the extracted samples to the technical department for inspection, Xiao Chen had just finished inspecting the scepter, and he excitedly told Dalong that although the scepter had been cleaned, it still found residual bloodstains, and it was already compared with the deceased Lin Jiahe and Lin Duoduo, and there were several vague fingerprints on the scepter, but the scepter had been cleaned, and the extraction work was a little difficult.

The two excited people encouraged each other, Dalong hurried to Wang Qin's office, which was empty, he called Zhou Wang, and Zhou Wang said that Wang Qin and they went to the scene to complete the vehicle.

Dalong ran back to his office and relayed Xiao Chen's words again with a sigh of relief.

Zhou Wang soothed: "Don't worry, all we have to do now is wait, wait for the results to come out!" ”

"Master, why didn't you say the murderer took the murder weapon away? If it is taken away, it is really difficult for us to deduce the order of killing, and we can't lock down the people who have something to do with Shi Yufen, at least to investigate the Lin family and those creditors. ”

"yes, why did he take the pipe away and leave the murder weapon behind?"

"Pipes? A pipe for gasoline out of the car? Using the siphon principle? Then you have to have a basin or bucket to take away the pipes. ”

Zhou Wang stared at Dalong intently, and suddenly slapped the table and said, "These things just need to be thrown into the fire!" There is no need to take it away. ”

"Master, are you a little bit ahead of your time, you haven't found out if there is less oil in the car, and you're starting to think about what to do with the tools you steal oil."

"The murderer couldn't clean up the scene, and he came up with a way to burn it, and if he could think of burning it, he could immediately think of gasoline, and then he could think of the garage...... That is to say, when the Lin family entered the house, the murderer had already found what he was looking for! ”

"Why do you say that?"

"Because the scepter never left his hand until it was placed on the garage tool shelf."

Dalong thought about it seriously, nodded and said:

"For a person who has just killed someone and is not very cool-headed, once he puts down this thing in his hand, he may not think about it again, that kind of situation is a bit tense, and he can't pay attention to too many aspects, and it is not easy for him to think about cleaning the murder weapon."

"Yes, that's what it means, the murderer killed Shi Yufen first, and found what he wanted in the study on the first floor, at this time Lin Jiahe came back, the murderer panicked, he saw the scepter in the study, and he didn't do anything, quietly followed Lin Jiahe into the kitchen, quickly knocked down Lin Jiahe, and knocked down the little girl who heard the movement and went downstairs, and then carried the murder weapon in his hand, stood there and began to think about what to do next?"

Zhou Wang's eyes seemed to have the scene of the crime: after a short blank of brain, the murderer thought of the idea of arson, he carried the scepter and wanted to go to the garage, he was more familiar with the layout of the villa, but the scepter was still dripping blood, he thought of cleaning, and when he thought it was cleaned, he quickly went to the garage and began to study how to get the oil out, and the scepter was set up on the tool rack.

"Then you say, if the murderer just strangled Shi Yufen and got what he wanted, and Lin Jiahe hadn't come back at this time, would he just leave and let the little girl go?" Dalong asked very lightly.

Zhou Wang was silent for a moment, but still shook his head.

He didn't know what the killer would do.

Once a wrong thing is done, it is like a lie, and they need to do one wrong thing after another to cover it up, until they can no longer cover it up, and they will have a fluke mentality, waiting for the negligence of others, and only when everything is revealed, they will regret not doing it at the beginning.

……

The results of Xiao Chen's comparison came out quickly, and the bloodstains on the scepter belonged to the Lin family and Lin Duoduo.

Zhou Wang immediately called Wang Qin and told him about the situation

Wang Qin was very excited and said:

"We checked the expenditure flow of Lin Jiahe and Shi Yufen, Lin Jiahe came back to the high-speed gas station in Yangjiang, just filled up the oil, and now the amount of oil in the car has bottomed out, coincidentally, Shi Yufen also added oil on the same day, and now the oil volume has bottomed out, the easiest way to extract the oil in the fuel tank, you need a hose, use the siphon principle, and then there is something to load the oil, and the trace inspection is looking for the scratches at the mouth of the fuel tank......"

Zhou Wang listened and did not interrupt.

“…… I'm going to call someone who had an illicit relationship with Shi Yufen right now to make an inquiry! In the end, Wang Qin said, and hung up the phone without waiting for what Zhou Wang was saying.

Dalong had been listening to the side, and when he saw Zhou Wang hanging up the phone, he asked Zhou Wang, "Could it be those men?" ”

Zhou Wang shook his head and said, "It's hard to say, but what did the murderer look for in the study?" ”

"Do you still think the murderer is a person?"

"If the cause of the murder was because Shi Yufen cheated on him, then it is unlikely that the murderers were two people."

Dalong hurriedly asked: "Is it possible that one person went in and the other waited outside the door......"

"If it was premeditated, there shouldn't be so much time between the death of the parents and the children, and wouldn't it be more convenient to bring your own gasoline cans? There are people who have just finished killing in the house, and they can still calmly refuel in the garage? Even if it's the middle of the night, if there is a security guard patrolling, what do you see? ”

"It doesn't matter if it's one person or two people, anyway, we have the inspection materials in our hands, find the suspect, and compare them."
