“Two different knives?” Zhao Donglai frowned upon hearing this.
"Team Zhao, our third team also has a new situation to report to you." Luo Fei also stood up and said.
"Say" Zhao Donglai nodded.
“Just now, my team members and I conducted an on-site simulation of the situation on the day of the crime, and found that Lin Gang could only stab the deceased in the lower back after he fell on the sofa. , but according to the description, Lin Gang was in a state of extreme panic at the time, so we think it is unlikely that Lin Gang would perform a last-ditch attack on the deceased who had completely lost his ability to resist," Luo Fei said unhurriedly.
"What do you mean?" When Zhao Donglai heard what Luo Fei said, he had some speculation in his mind, but he still asked.
“I think that on the night of the crime scene, in addition to Lin Gang and Cheng Zhiyou, there was a third person who entered the crime scene. He entered the scene after Lin Gang left and found that Cheng Zhiyou was not dead. He was stabbed twice in the waist." Luo Fei expressed his speculation.
"The third person? Is it Cheng Wei?"
"It should be him right. Judging from Lin Gang's interrogation, Cheng Wei's reaction was very wrong."< br>
Everyone in the conference room started talking after hearing Luo Fei say that there was a third person at the scene of the crime who had stabbed the deceased.
"Do you suspect it's Cheng Wei?" Zhao Dong came to look at Luo Fei and asked.
"Yes, according to the current conditions, Cheng Wei is the most motivated to commit the crime." Luo Fei nodded affirmatively.
"If it is true that Cheng Wei entered the crime scene and injured the deceased twice, then Cheng Wei should have climbed in from the iron railing behind the community like Lin Gang." Yang Su thought for a moment. He said that because a group checked the surveillance at the gate of the community, there was no record of Cheng Wei entering or leaving the community that night.
“If Cheng Wei really entered the crime scene and harmed Cheng Zhiyou a second time, then I think the most important thing for us at the moment is to grasp the evidence that Cheng Wei entered the crime scene as soon as possible, and to find out The most critical weapon." Zhao Donglai brought up the two most urgent points at the moment.
“In this way, Group 1, Group 4 and the technical team immediately conducted a comprehensive search of the crime scene, the community and the surrounding area to see if they could find evidence that Cheng Wei entered the crime scene.”
"The second and third teams went to investigate Cheng Wei's movements on the day of the incident, and find out where Cheng Wei went that day, and the knife. It is very likely that Cheng Wei bought it recently. If that is the case, As long as we can find evidence that Cheng Wei purchased the knife, it will be of great help to us in solving the case." After confirming that there was a third person at the scene of the crime and that the murderer was most likely Cheng Wei, Zhao Donglai immediately took up the task. Distributed.
"Let's see if you have anything else to say? If you don't have anything to say, let's just carry out the task according to the arrangements just now." Zhao Dong came to ask the people below.
"Captain Zhao, Lin Gang, we didn't ask clearly about the two wounds on the lower back before. Should we interrogate again?" Luo Fei reminded, before everyone thought that the wounds on the deceased were all Lin Gang got it out, and he never thought that another criminal suspect would perform a last-ditch attack on the deceased.
"Yes, I almost forgot about this. Luo Fei, you will interrogate Lin Gang again immediately to confirm whether these two wounds were caused by Lin Gang." Zhao Donglai ordered.
End of meeting
Luo Fei immediately brought Lin Gang up for interrogation.
Interrogation Room
"Lin Gang, what you told us before was that you stole money and took the knife to embolden your courage, right?" Luo Fei asked Lin Gang, who was already looking very haggard.
"Well, that's it. Actually, I didn't think of holding a knife at first. It was Cheng Wei who reminded me. He said that if you hold a knife, you can use it to scare people even if you encounter a situation. I think so, so I brought my usual dagger." Lin Gang replied.
“That’s it.” Luo Fei nodded.
"By the way, do you still remember how many times you stabbed Cheng Zhiyou?" Luo Fei continued to ask.
Lin Gang shook his head, "I don't remember this. I only remember that I stabbed me once, and then he grabbed my shoulder. I couldn't struggle away, and stabbed me several times in a row, and then I pushed him to the sofa. I saw that he was unresponsive and ran away."
"Are you sure you didn't stab Cheng Zhiyou again after he fell on the sofa?" Luo Fei? He asked, staring into Lin Gang's eyes.
"No, I don't want to kill anyone. I just want to escape. How can I think of stabbing him again?"
Luo Fei saw that Lin Gang looked natural and didn't look like he was lying. , it is basically certain that the two knives on the deceased’s waist were not stabbed by Lin Gang.
Group Three Office
Luo Fei has just returned to the office
"Sun Jun, take out the map." Luo Fei quickly walked to the case analysis board and said to Sun Jun hurriedly.
Sun Jun quickly walked to the bookcase at the back of the office and took out a folded drawing from the bottom table.
Then he quickly returned and gave the drawings to Luo Fei.
Luo Fei opened the drawing, which was a detailed map of Ningjiang County.
Luo Fei then placed the map on the case analysis board with a magnet.
Use chalk to mark the six residential areas where the deceased Cheng Zhiyou lived.
"This is the sixth community where the deceased was located. There are monitoring points around the six communities, which are here and this." Luo Fei said using chalk to mark the surveillance points around the six communities one by one.
"Sun Jun, you and Zhao Cheng first go and copy all the surveillance videos from these cameras on the day of the incident. We will check the surveillance videos at night." Luo Fei ordered.
"Yes"
"Yes"
Sun Jun and Zhao Cheng nodded in reply.
"Wang Yong, Zhang Fan, you two first go ask the neighbors around Cheng Zhiyou to see if Cheng Zhiyou is used to going home around ten o'clock in the evening, and then you two will go investigate the shops selling knives on the market. Let's see if we can find out about Cheng Wei's purchase of knives. I'll go to the Internet Security Team to check Cheng Wei's online consumption records," Luo Fei then said to Wang Yong and Zhang Fan next to him.
After the tasks were arranged, the three groups of people set out collectively.
Luo Fei first found Zhao Donglai and asked Zhao Donglai to help contact the Internet Security Brigade, which Luo Fei was not familiar with.
Zhao Donglai called the captain of the Internet Security Brigade without saying a word, and soon he contacted Zhang Yao, the captain of the Internet Security Brigade.
Luo Fei drove directly to the Internet Security Brigade and found Zhang Yao, the captain of the Internet Security Brigade.
"Captain Zhang, I am Luo Fei from the Criminal Police Brigade." Luo Fei introduced himself directly to Zhang Yao.
"Haha, no introduction is needed. You are now a celebrity in our Ningjiang County public security system. You have arrested the three gangsters in Jiang, solved serial murder cases, and are Ningjiang County's outstanding police officers of the year. It's hard for me not to know you. And I have met you at several commendation conferences before," Zhang Yao said with a smile.
"Captain Zhang is overly praised." Luo Fei said politely.
"Captain Zhao has already told me the situation. I originally wanted to talk to you, but since you are investigating the case, I won't waste your time. Let's go find Xiao An."
Then Zhang Yao took Luo Fei to a computer room. There were four young Internet police officers in the room who were working online. Everyone was very serious. When Luo Fei and Zhang Yao approached, No one found out.
"Xiao An, comrade from the criminal police team needs your help to check something. Please check it for him." Zhang Yao patted the young girl in front who was writing code. The girl turned her head and saw Luo Fei and Zhang Yao.
"Captain, what are you doing? I'm writing code!" the girl said unhappily. The girl looks very good-looking, a bit like the girl next door. Judging from her childish expression, she is probably not very old. She should be like Luo Fei. almost.
Zhang Yao glanced at Luo Fei with a helpless expression on his face, and then looked at the girl, "Comrade from the criminal police team needs your help to check something."
The girl then looked towards Luo Fei then showed a surprise expression on his face.
"You are Luo Fei, the one who caught Jiang Sanqiang. I know you. You are really amazing. You have solved so many cases." The girl said in surprise.
"I am Luo Fei." Luo Fei nodded. Looking at the girl's expression, he felt that the girl seemed to admire him.
"He is Luo Fei"
"It's really Luo Fei, he is very good at solving crimes"
The several Internet policemen who were working hard just now also looked at Luo Fei. Discuss softly.
"Okay Xiaoan, Luo Fei has a case to investigate. Help him check something online." Zhang Yao, who was standing next to him, saw that his subordinate was looking a little crazy and quickly reminded him.
"By the way, you must be investigating murder cases. Luo Fei, what do you want to investigate?" The girl named Xiaoan quickly asked Luo Fei.
"Cheng Wei of Community Six, ID number xxxxxx, please help me check Cheng Wei's online shopping records in the past three months." Luo Fei replied.
"No problem, it's a joke." Xiao An gave Luo Fei an OK gesture, and then tapped flexibly on the computer keyboard with his ten fingers.
Only ten seconds passed.
"OK, done." Xiao An took his hands off the keyboard, then turned to look at Luo Fei.
"Luo Fei, take a look and see if there is any information you need?" Xiao An said, stood up and gave up his position to Luo Fei.
Luo Fei was not polite, sat down directly, and browsed carefully.
Three months of online shopping records were very complicated, but Luo Fei read them very quickly. He finished them in a short time and made a surprising discovery.
On January 7th, Cheng Wei bought a knife online, which was the same type as Lin Gang's.
“Can I print this online shopping receipt?” Luo Fei asked.
“Just print it out, it’ll be fine.” Zhang Yao smiled, and then asked: “Are there any clues you need?”
"Yes, I really want to thank Captain Zhang and..." Luo Fei said and looked at the girl next to him, whose name he didn't know.
"Anqi, my name is Anqi, remember." The girl emphasized.
"Yes." Luo Fei nodded in agreement.
After printing out Cheng Wei's online shopping order, Luo Fei left the Internet Security Brigade and returned to the Criminal Police Team.
And reported the situation to Zhao Donglai immediately. At about three o'clock in the afternoon, good news came from the technical room. They extracted a set of shoe prints from the lawn outside the community and compared them. It was confirmed to be Cheng Wei's.
Wang Yong and Zhao Cheng from the third group also brought good news. They found out that Cheng Zhiyou would go running in the square at night and had the habit of coming back at ten o'clock in the evening.
There is also good news. Luo Fei and Sun Jun checked all the surveillance cameras around the Sixth Community and found Cheng Wei. At one o'clock in the evening on the night of the incident, Cheng Wei was on a street not far from the Sixth Community. Wei left in a hurry.
With this evidence, at five o'clock in the evening, Luo Fei and Sun Jun interrogated Cheng Wei again.
"I have told everything I know. I admit that I am guilty. I should not have let Lin Gang steal money." Cheng Wei had an indifferent look on his delicate face.
Luo Fei said nothing and kept staring at Cheng Wei.
After waiting for several minutes, Cheng Wei's calm face flashed with a trace of annoyance, "What do you mean by looking at me like this?" At what point would he kill his father?" Luo Fei finally said calmly.
"I don't know what you are talking about?" Cheng Wei looked at Luo Fei with a livid face.
"You don't know? But God knows, there is an old saying that if you don't know what to do, don't do anything except yourself. Do you think your plan is perfect? Don't be stupid, there is no perfect murder at all. We have already We have conclusive evidence that you murdered your father," Luo Fei said coldly.
Hearing this, Cheng Wei frowned and looked at Luo Fei. He didn't know whether Luo Fei's words were true or false.
"Comrade police, are you kidding me?" Cheng Wei's face turned cold.
"Just kidding, I never joke. Do you think that by throwing Lin Gang out as a scapegoat, you can hide the truth? The purpose of letting Lin Gang steal money is not for money. , but in order to kill your father, Lin Gang was the scapegoat you found. You asked Lin Gang to go to the room to steal money around ten o'clock. That was Because you know that your father goes for a run in the square every night and is used to coming back at ten o'clock. "
"You let Lin Gang carry a knife. On the one hand, it increases the chance of Lin Gang killing your father, but most importantly. The reason is to put your murder charge on Lin Gang and clear yourself of suspicion, because you are going to use the same knife as Lin Gang "Kill your father."
"On the day of the second grade of junior high school, you waited for Lin Gang to leave, sneaked over the wall into the community, opened the door and entered the room. Your idea was that if Lin Gang didn't kill you, Father, you kill your father yourself, but you find that your father has been stabbed by Lin Gang and is lying on the sofa. The situation is progressing more than you imagined. Okay, but you found out that your father was only stabbed and not dead. You were worried that your father would not die, so you took out the prepared knife and stabbed your father twice before leaving the scene.”
"This is the story of your crime. There shouldn't be anything wrong." Luo Fei said but stared at Cheng Wei.
Cheng Wei's handsome brows were already furrowed at this time. He boasted that the case was done flawlessly, but why could the police describe all the details of his crime so clearly?
"Comrade policeman, you are really good at making up stories. If you don't become a novelist, it would be a pity to be a policeman." Cheng Wen said coldly.
"Haha, writing novels is not as exciting as reality. The most exciting plots all happen in real life, and I like to catch bad people?" Luo Fei sneered, then looked at Cheng Wei and asked :"Do you know what's the biggest mistake you've ever made?"
Cheng Wei didn't say anything, just looked at Luo Fei.
Luo Fei smiled and said: "That means you underestimated the IQ of our police officers, and at the same time you overestimated yourself. Another thing is like you said, writing novels is not the same thing as reality. Do you think A perfect script can only exist in a novel, and there is no perfect crime in reality.”
Cheng Wei looked at Luo Fei, and after a while he said: "Comrade police, have you forgotten what I told you? On the night of the crime, my girlfriend and I stayed together. How could I be at the scene of the crime?"
“This is a good reason, but it is also very selfish. Do you think you are selfish for letting your girlfriend commit a crime instead of yourself?" Luo Fei glanced at Cheng Wei indifferently, and then said coldly: "You said you were with your girlfriend all night, what about this surveillance video? Something."
Luo Fei said, showing the surveillance video to Cheng Wei.
