Yu Chen and Yuan Youchong, Gu Yandong and Lei Huailu, the two groups of people came out of the interrogation room almost at the same time, so they raised their hands to say hello to each other, and then got together and asked in unison: "How is the situation over there?"
Yu Chen and Gu Yandong pursed their lips at the same time, and then, Yu Chen said, "You speak first."
"Well," Gu Yandong nodded: "The suspect we are responsible for the investigation is named Lin Huidong, and Shuangmulin is a KTV manager" "Although his patience has almost been exhausted, after some questioning, Lao Lei and I still think that we can basically rule out his suspicion of committing the crime, and writing it down is to confirm his confession and find out his interpersonal relationships."
"That's right."
Yu Chen was a little disappointed: "The situation on our side is similar.
The suspect's name is Xie Hao, the photographer, who is very cooperative in his attitude, and has preliminarily ruled out his suspicion of committing the crime. ” "That" Gu Yandong asked tentatively: "Continue" "Go ahead, or split up."
"Okay."
By lunchtime, the five suspects had completed their second investigation.
It is a little disappointing, but as expected, this investigation still did not yield anything, and the five suspects were ruled out as direct suspects.
"This case is much more complicated than I imagined."
At the dinner table, Yu Chen rubbed his eyebrows and asked, "Si Junnong, you have tried to investigate, have you seen all the surveillance, have you found anything?"
Si Junnong shook his head: "Just like the director said, Xiong Da's suitcase is placed in the blind spot of monitoring. ” "Then it won't be nothing," Yu Chen frowned: "Whoever has approached that blind spot must be counted."
"Uh" Si Junnong scratched the back of his head: "In fact, Xiong Da, as well as the five suspects currently under investigation, as well as the attendants of the commercial car, without exception, have all entered the blind spot of surveillance. ” "Or to put it this way, as long as you enter the business car, you have to go through that small monitoring blind spot, which is located in the corner of the car and is blocked by two row seats."
"The angle of the camera, although it can shoot the passenger, or the upper body of the suspect, but the movement of the hand cannot be filmed, as long as the hands and feet are fast enough, Xiong Da's suitcase can be completely replaced.
However, if you want to empty the gloves of the white wolf, it is also a fool's dream. ” "Oh" Yuan You rushed to his senses and sat up straight: "In other words, it can be determined that the only feasible way for the suspect to commit a crime is to replace it with a suitcase of a similar style or simply the same style with a suitcase containing a golden pig, right?"
After thinking about it, Si Junnong nodded, but the narrative was still relatively conservative: "Theoretically, that's the case. ” "Hmm."
Yuan Youchong had an idea: "Immediately notify your department and our colleagues who are good at gait analysis to come over and monitor again." ” "I think that the weight of the same suitcase should be less than half of the weight of the stolen suitcase, and the weight of the things in the hand has changed, and the gait and hand movements will definitely change accordingly."
The director immediately spoke: "We have two colleagues in the institute who are also good at this, and I told them to come over and help." ” "That's for the best."
Yuan Youchong smiled, and then said: "In this way, you can directly rule out the suspicion of Xie Hao and Lin Huidong, their suitcases are quite different from the one stolen by Xiong Da, and there is no possibility of replacement." ” "And the last business traveler, Wang Zhao, is relatively suspected of committing the crime" "Uh, Team Yuan, I have a question," the director interrupted Yuan Youchong's narration and asked curiously: "Wang Zhao's suitcase, we have opened the box and checked it, and there is no problem, why do you still say that he is suspicious?"
"The suitcases of the two second-class passengers, don't you also open the suitcases and check them" Yuan Youchong asked rhetorically, and then said: "Before and after the incident, in addition to our police, there were only four business travelers, two second-class passengers, and a flight attendant, seven people." ” "The thief must be among the seven, there is no doubt about it.
The suspicion of the flight attendant is temporarily ruled out, and she also does not have the conditions to directly commit the crime; Xiong Da doesn't think about it for the time being, so won't only Wang Zhao and the others be left?"
"In this case, we can't be fooled by performance.
Indeed, Wang Zhao's suitcase, you have checked, but there is another possibility, you did not consider that if Wang Zhao first replaced Xiong Da's suitcase, and then replaced it with two second-class passengers who strayed into the business car" The director suddenly realized: "Yes, when you were in my office, you actually made this guess.
In the same way, the other two also used this method to avoid inspection."
"Yes."
Yuan Youchong said: "In fact, the two of them are the most suspected of committing the crime. ” "You think, the excuse that a second-class seat strayed into the business car sounds a bit nonsense.
Moreover, after they get off the train, whether it is a second-class carriage or a platform, they can use four words to describe the crowd of people. ” "In this case, it is actually very easy to replace the suitcase in your hand again without realizing it and avoid the shooting of the surveillance probe."
"Therefore, no matter from the consideration of the conditions for committing the crime, the difficulty of the crime and the reasonableness of the behavior, these two people are suspected of committing the crime among the five people, and I think that the focus of the next investigation should be on the two of them, and strive to find a breakthrough."
"Actually," Yu Chen pursed his lips and said, "I also thought of a possibility. ” "Oh" Yuan Youchong looked at him and said with interest, "Tell me about it." ” "His suitcase, will it have been replaced after passing the security check" Yu Chen said: "The X-ray of the security inspection machine has a perspective function, and there is nothing to hide in the suitcase, so his golden pig should not have been stolen at this time." ” "But after passing the security check, it is the waiting room, which is big enough, there are many people, and he stays long enough, it is entirely possible that the golden pig was stolen and replaced by the real criminals at this time."
"After that, he boarded the car, and his suitcase was targeted by another group of people, but since the real target had already been replaced, we launched an investigation into these people and their luggage, and naturally found nothing."
"It's a possibility."
After listening, Yuan Youchong bowed his head slightly, followed closely, and his words changed: "But, don't you think that when you think about it, the direction of the investigation is too big to start at all?"
"There are so many things that are actually not much different from no clues, and we have to pull a thread out of it and sort it out gradually.
It's better to follow my train of thought first, one way to the dark, it's really not good, and then follow your guess.
