Luo Fei stared at Cheng Wei, this guy was not slow to react, knowing that the police could easily confirm that Zhao Yi was pregnant, so he directly confessed that he lied to Lin Gang.

"After knowing that Lin Gang killed your father, not only did you not think about calling the police to arrest Lin Gang, but even wanted to help Lin Gang escape the punishment of the law, does this mean that you have no feelings for your father at all?" Luo Fei stared at Cheng Wei and asked.

Cheng Wei shook his head, "No, I have a good relationship with my father, I was extremely sad after I knew that my father was killed by Lin Gang, this is the father who gave birth to me and raised me, and it is also my only relative in this world." ”

"I want to call the police to arrest Lin Gang, but what can I do? Could it be that if Lin Gang is caught, my father will be able to come back? This can't, when people die, they die, and Lin Gang is my good friend, and I also asked him to steal money, in a way, it was my reason that caused this tragedy to happen, and I have a lot of responsibility. ”

"So after thinking about it for a long time, I gave up the idea of calling the police to arrest Lin Gang, of course, I was also afraid that the police really caught Lin Gang, and Lin Gang would implicate himself as soon as he confessed, after all, my father is gone, but I still have to live, Xiaoyi is still waiting for me, I can't have an accident, I can't let Xiaoyi lose me and live alone."

Cheng Wei's remarks can be said to be leaky, obviously it should have been thought of a long time ago, Luo Fei didn't believe that Cheng Wei could make up such a complete statement.

"You lied, we learned that you don't have a good relationship with your father?" Luo Fei asked coldly.

"That's a misunderstanding of us by outsiders, we have a good relationship between father and son, but we just don't show it." Cheng Wei explained.

Luo Fei didn't ask again, he knew the current situation, even if he asked again, he couldn't ask anything, he glanced at Cheng Wei coldly, and then beckoned Sun Jun out.

Soon Luo Fei and Sun Jun left the interrogation room together.

Outside the interrogation room, Zhao Donglai and Zhang Fan, the leader of the second group, were both there.

"Team Zhao, this guy is very calm and cunning, if you can't find tangible evidence, I guess it's difficult to get him to tell the truth." Luo Fei reported to Zhao Donglai.

Zhao Donglai frowned, he also saw the situation in the interrogation room just now, this Cheng Weiyi seems to be a very calm and intelligent person, this kind of person is really difficult to deal with.

"Cheng Zhiyou's murder, it can be said that from beginning to end Cheng Wei just asked Lin Gang to steal money, plus some time coincidences, it caused this seamless murder, and the other Cheng Wei didn't do anything, this seems to be an accident at all, we want to find evidence of Cheng Wei's murder, unless Cheng Wei takes the initiative to admit it, I think it's difficult." Zhang Fan also said with a solemn face.

Luo Fei didn't speak, judging from the current situation, I have to say that Cheng Wei used an accident to kill Cheng Zhiwei, which is indeed a very clever technique, it is really difficult to find evidence in this case, but Cheng Wei really didn't do anything except let Lin Gang steal money?

"It's really difficult, but no matter how difficult it is, we have to solve it, and the purpose of our criminal police is "murder cases must be solved" and "no bad guy can be spared". Zhao Donglai first said firmly, and then looked at Luo Fei and Zhang Fan, "You go down, think about how to investigate this case, and at twelve o'clock in the meeting, we will hold another temporary meeting in the conference room, gather everyone, and then discuss it." ”

"Yes"

"Yes"

Zhang Fan and Luo Fei nodded.

Luo Fei came out of the interrogation room and went directly back to the three groups of offices.

In the office, Sun Jun and the others were discussing the case.

"It's really difficult to do now, except for the fact that Cheng Wei instigated Lin Gang to steal money, the case of Cheng Zhiyou's murder can be said to be an accident, how can you find evidence?" Wang Yong looked irritable.

"Yes! How do you find evidence for this? It's too hard to find evidence. Zhao Cheng also followed.

Sun Jun said: "There can be no perfect murder, as long as it is a murder, there will definitely be evidence, but we haven't found it now." ”

Luo Fei also agreed with Sun Jun's words, there can be no murder without flaws, as long as it is a murder, it will definitely leave clues.

"Team Leader"

"Team Leader"

Seeing Luo Fei coming in, Sun Jun greeted Luo Fei one by one.

"Well, come here, at twelve o'clock in the meeting, Team Zhao will hold an impromptu meeting to analyze the case, and we will have a brief meeting within the group to discuss it." Luo Fei walked to the case analysis panel.

Luo Fei wiped the blackboard clean, and Sun Jun and a few people came over.

"Now let's put together our thoughts."

"First of all, let's presuppose that Cheng Wei is the murderer of Cheng Zhiwei?" Luo Fei said, raised his hand and wrote Cheng Wei - the murderer on the blackboard, and then wrote the reason and the conditions for the murder next to him.

"Secondly, it is the reason, why did the murderer kill Cheng Zhiyou, he and Cheng Zhiyou are a father and son, what kind of hatred is there between them?"

"Another point is that the murderer wants to carry out his own murder plan, so what about the murder conditions." Luo Fei pointed to the blackboard and asked continuously.

"The reason for the murder is unknown, but the conditions for the murder are obvious, one, let Lin Gang go to the room to steal money, and two, when Lin Gang stole money, Cheng Zhiyou just came back." Sun Jun replied.

"Then there are two problems in this, first of all, how can Cheng Wei be sure that when Lin Gang stole the money, Cheng Zhiyou just came back, you must know that Lin Gang went to the room to find the money in the bedroom, and then went out, all of which add up to ten minutes at most, how can Cheng Wei guarantee that Cheng Zhiyou will come back within ten minutes." Luo Fei asked.

"This" Sun Jun thought about it, but he couldn't think of a suitable reason for a while.

"Could it be that Cheng Wei called Cheng Zhiyou and asked Cheng Zhiyou to come back." Wang Yong looked at Luo Fei and asked.

"The people of the second group checked the deceased's communication records, and the deceased did not receive any phone calls that night." Luo Fei shook his head and replied.

"Secondly, Lin Gang robbed the house and was bumped into by Cheng Zhiyou, why did Lin Gang kill Cheng Zhiyou? There are cases of burglary and murder, but it is a small probability event, Cheng Wei really wants to murder Cheng Zhiyou, do you think he is gambling on this kind of small probability event? Luo Fei continued to ask.

Sun Jun shook his head, "This probability is too small, Cheng Wei wants to murder Cheng Zhiyou in this way, I think it is unlikely to work unless it is lucky." ”

"But the reality is that Cheng Wei did it, Lin Gang successfully killed Cheng Zhiyou, do you think this is a small probability accident?" Luo Fei then asked again.

The members of the three groups either frowned or scratched their ears and cheeks.

"I can't figure it out." Wang Yong felt that his brain cells were dying rapidly, and he really couldn't figure it out, and then gave up thinking completely.

"In fact, the first point should be easy to figure out, that is, the problem of habits, Cheng Wei and Cheng Zhiyou are father and son, Cheng Zhiwei should know all the work and rest habits of Cheng Zhiwei."

"I estimate that Cheng Zhiyou should have a habit, most of which is a daily habit, that is, to come back around ten o'clock in the evening, so Cheng Wei will let Lin Gang go over at ten o'clock to steal money, so that the probability of Lin Gang and Cheng Zhiyou colliding will be infinitely larger, as for whether this is the case, let's find the neighbors around Cheng Zhiyou to verify it."

"One more point, have you ever thought about it, Lin Gang went to steal money, and there is a certain irrationality in holding a knife, and it is not a burglary, just to steal money, I think few thieves will steal money with a knife, right?"

"Secondly, the deceased Cheng Zhiyou was stabbed a total of eight times, Lin Gang burglarized, was discovered by Cheng Zhiyou, according to the logical thinking of normal people, the first thought at this time must be to escape, but according to Lin Gang's own confession, his head was blank at the time, so he stabbed him with a knife, Cheng Zhiyou grabbed his shoulder, and he stabbed and slashed Cheng Zhiyou indiscriminately."

"It's nothing, but I thought about it carefully and simulated the scene in my mind, but no matter what, the direction of the two stabs on the deceased's back and back can't be explained."

"Just now, taking this opportunity, let's decorate the office, let's simulate the scene at that time, and see under which circumstance Lin Gang can cause two stabs on the deceased's waist." Luo Fei commanded.

Then several people roughly arranged the office according to the furnishings of the deceased Cheng Zhiyou's living room.

"In this way, Wang Yong plays the deceased Cheng Zhiyou, Sun Jun plays Lin Gang, you should all know the situation, but I still tell you, first of all, the deceased entered the door and turned on the light, and saw Lin Gang who was about to leave, Lin Gang saw the deceased directly stabbing the deceased with a dagger, the deceased grabbed Lin Gang's shoulder, Lin Gang couldn't break free all of a sudden, stabbed and chopped indiscriminately, the two scuffled together, and the deceased finally fell on the sofa." Luo Fei explained the situation.

"Captain, can I not play the dead?" Wang Yong grimaced.

"You are about the same height and size as the deceased, you don't come to play the deceased, who plays the deceased, don't beep." Sun Jun said dissatisfiedly.

"Okay, get ready, remember that from this moment on, the two of you are the murderer and the dead, let's start, go the three of us over there, don't affect the two of them." Luo Fei handed Sun Jun a piece of chalk to use as a knife, and then walked to the side with Zhang Fan and Zhao Cheng next to him.

Then Wang Yong walked out of the room and closed the office door.

Sun Jun holds the bag in his left hand and the chalk in his right.

"At this time, the pen should be in your pocket." Luo Fei frowned and reminded Wang Yong.

When Sun Jun heard this, he hurriedly put the pen in his pocket.

The deceased played by Wang Yong opened the door and entered the house, turned on the light next to him, and then saw the murderer played by Sun Jun in the living room.

The two were stunned for a moment, and then Sun Jun took out the chalk and stabbed Wang Yong fiercely.

Wang Yong was stabbed, but it was not fatal, Wang Yong immediately grabbed Sun Jun's shoulder, Sun Jun wanted to break free, but he couldn't break free, and then Sun Jun frantically slashed and stabbed Wang Yong.

Wang Yong had already entered the play at this time, and subconsciously hugged Sun Jun, and the two scuffled together.

Later, the deceased played by Wang Yong was pushed down on the sofa by the murderer played by Sun Jun because of excessive blood loss and physical exhaustion, and Sun Jun saw that the deceased had no movement, so he hurriedly left the room.

"Team leader, how's it going?" As soon as it was over, Wang Yong got up and hurriedly asked.

Luo Fei looked at the chalk marks left on Wang Yong's body, except for the marks on his abdomen and hands, there were no marks on his lower waist, and then frowned.

"No, do it again, this time, the two of you scuffled together, and then the two fell on the sofa together, and the murderer also made up for the deceased on the sofa, and he had to be stabbed in the back of the waist." Luo Fei said.

Sun Jun and Wang Yong didn't have much to say, and the simulated case must be tried again and again.

Then the two of them conducted a new simulation.

"No, Wang Yong, the deceased you played should not have the strength to resist at this time."

"No, Sun Jun, you are the murderer, you are holding a knife in your hand at this time, what about your knife?"

In the office, Luo Fei recalled the scene of the crime in his mind, and corrected the actions of Wang Yong and Sun Jun over and over again.

However, no matter how it is simulated, there is no way to explain the direction of the two knives on the deceased's lower back, and Sun Jun wants to make the direction of the knife the same as the direction of the wound on the deceased's lower back, so he can only use a very awkward posture, which is not logical.

There is only one case where Sun Jun stabs Wang Yong, and the direction of the knife on Wang Yong's back waist is almost the same as the direction of the wound on the deceased's lower back, that is, after the death of the deceased played by Wang Yong, Sun Jun walked to the middle of the sofa and mended the deceased.

"So, Lin Gang made up for the deceased after he collapsed on the sofa? But didn't Lin Gang say that he was panicked at the time? How could you think of mending the knife, could it be that Lin Gang lied? Sun Jun asked.

Luo Fei also frowned, it really doesn't make sense to mend the knife, but if you want to say that Lin Gang is lying, Luo Fei doesn't think it's like it.

But if Lin Gang didn't lie? So does it mean that there was a third person at the scene, he waited for Lin Gang to leave, and saw that the deceased was not dead, so he made up the knife.

Cheng Wei

Almost immediately, Luo Fei thought of Cheng Wei, a delicate and calm person.

Could it be that from the beginning, Lin Gang was the scapegoat that Cheng Wei had found, Cheng Wei thought that Lin Gang could kill Cheng Zhiyou, and if Lin Gang hadn't killed Cheng Zhiyou, Cheng Wei would have killed Cheng Zhiyou himself and blamed Lin Gang.

So after Lin Gang killed, Cheng Wei entered the room, checked the situation, and saw that the deceased was only stabbed and did not die, so he made up two more knives.

Just when Luo Fei was thinking frantically.

"Team leader, twelve o'clock, the meeting is over." Wang Yong reminded beside him.

"Let's go, then."

Then the three groups of people rushed to the conference room together, and the people from the criminal police team were almost here in the conference room.

After waiting for a while, when everyone had arrived, Zhao Dong came to let everyone talk about the current situation.

"Team Zhao, there is a new situation on the forensic doctor's side, which I just discovered, and I haven't had time to report it to you yet." Yang Mei said.

"What's the situation?" Zhao Dong looked at the technical room.

The forensic doctor pony in the technical room got up and replied: "That's the Zhao team, after we dissected the corpse, we found that several knife wounds on the deceased's body were somewhat different, we found that the deceased had four stab wounds on his abdomen, and the wound was obviously a large piece of contusion and abrasion skin, while the two wounds on the deceased's back waist were neat and smooth and did not have any contusions. ”

"So we suspect that the knife wounds on the deceased should have been caused by two knives of the same shape, but with different sharpness."

On the other side of the three groups, as soon as Sun Jun and the others heard the words of the forensic pony, they immediately looked at Luo Fei in unison, which was completely consistent with the situation they simulated just now.
