Chapter 283 The Doubt That Meng Qinghan Discovered (2)
Chapter 165: The doubts discovered by Meng Qinghan (2)
"The real intention of the murderer behind the scenes is to use the trap to create an accident in which a garbage truck crashes into a bungalow, attracting the two Ushi brothers, and then use the help of our police to get rid of them!"
After Meng Qinghan said these words, everyone was shocked. Even Deputy Director Yang no longer mentioned why the other party was absent from work these two days, but asked with a surprised look: "Xiao Meng? This matter
You can’t just talk nonsense, are you sure?”
"Deputy Director Yang, I'm sure there is someone else behind this incident!"
Meng Qinghan said firmly, then pointed to the large evidence bag on the table and explained: "In order to make it easier for everyone to understand what I want to express, I specially put all the evidence found in the past two days
We have all been brought here, please take a closer look."
At this time, everyone, including Deputy Director Yang, put down what they were doing, and the police officers from the Second Investigation Brigade came over with curiosity on their faces.
After all, Meng Qinghan is a captain who parachuted in from outside the country, and it will soon be revealed how many tricks this person has.
After a while, Meng Qinghan first took out a report record from the police reception desk from the evidence bag and explained.
——"Please see, everyone, this report record from the police reception desk clearly shows that a call came in at 8:55 on the day of the incident involving Zhao Luobo and others."
——"The man who made the call is named Li Youzi. He said that he and his wife Zhang Xiaoyun were in the back alley of Mobei Hongdu on Tianjin Road at this time. If they could not get their wages, they were planning to hang themselves there."
——"Afterwards, the dispatch desk immediately arranged for Zhao Luobo and his team to go to the scene to call the police, but the couple who called the police were not found."
——"But when Zhao Luobo asked the manager of Mobei Hongdu about this, he accidentally saw the garbage truck that crashed into the bungalow."
——"In the end, the two Wu brothers came out and discovered the conflict with Zhao Luobu."
Upon hearing this, Deputy Director Yang also asked patiently: "Xiao Meng, what you said is indeed correct, but these are things that everyone already knows."
Meng Qinghan nodded, "I'm going to talk about some things that everyone doesn't know."
Subsequently, Meng Qinghan opened an audio editing software called Adobe Audition on the computer in the command room, and then used this software to open the phone recording of the police station at that time. Suddenly, the visual waveform pattern of the recording at that time appeared on the screen.
Meng Qinghan first played the 1 minute and 55 seconds of the alarm recording, but soon someone raised questions.
Only one police officer was heard asking: "Captain Meng, in this recording, why did the person who called the police seem to have given two identical answers just now?"
Meng Qinghan: "Yes! Between the 35th and 50th seconds of the recording, the reporter is telling what happened to him and providing his location to the police station. But the exact same paragraph is different.
Repeatedly between 75 seconds and 90 seconds."
Later, Meng Qinghan specially excerpted the recordings from these two time periods and played them one after another, but everyone heard two identical recordings.
"I...my name is Li Youzi! My wife's name is Zhang Xiaoyun! We are now in the back alley of Mobei Hongdu on Tianjin Road. Let me tell you! We have been working for this nightclub for a year. In the end,
We didn’t get a penny! If you police don’t come, we will hang ourselves here right now!”
Subsequently, Meng Qinghan created a new folder in the software, placed the two recordings in an audio track at the same time, and enlarged the visual waveform pattern of the audio. After stretching it to the limit, he explained.
——"Just imagine, if you were asked to read two identical passages, it would be difficult for you to ensure that the tones and pauses in the two passages are exactly the same."
——"But in this software, we can see that the peaks and troughs of the two sentences between 35 seconds to 50 seconds and 75 seconds to 90 seconds by the reporter are completely consistent with the decibel display, not even milliseconds.
Difference."
——"This can never be a coincidence that humans can do, so the only possibility is that this passage was recorded by the murderer in advance and played back to our responding officers through the police phone at that time!"
——"And the murderer must also know about our "3-minute police dispatch" action during this period, so his purpose is to attract our police officers to the back alleys of Mobei Hongdu to implement the follow-up plan."
After the conversation, everyone completely believed Meng Qinghan's analysis.
At the same time, in the Second Investigation Brigade, the old police officers who were very resistant to this kind of "airborne captain" behavior suddenly fell silent and stopped talking, and no one bothered anymore about why Meng Qinghan didn't visit Zhao Luobo in the past two days.
matter.
Because everyone already knows that the most responsible behavior towards Zhao Luobo is to do your best to solve the case in the shortest possible time and catch the real culprit behind the scenes. Other than that, all other words of comfort and warm-hearted behavior are
Imaginary.
But at this time, after Meng Qinghan gave everyone ten seconds to think, he immediately placed other evidence in front of everyone.
Meng Qinghan: "Everyone, if it is just a pre-recorded alarm call, it cannot actually be used as a conclusion to transform this case from an accident to an intentional homicide. Therefore, we need to combine other evidence to make a joint conclusion."
Deputy Director Yang was surprised and said: "Xiao Meng, what do you mean? In this incident, you also have other evidence?"
Meng Qinghan nodded and explained.
——"Yes! In the past two days, I have carefully analyzed the necessary prerequisites for the murderer's plan."
——"Respectively, 1: The police were dispatched at 3 minutes. 2: The garbage truck came to collect the garbage on time at 8 o'clock every morning. 3: The two Wu brothers had to be in the bungalow at that time."
——"Point 4 is also the most important point in this murder. Please watch the big screen."
After finishing speaking, Meng Qinghan opened a photo on the big screen in the command room. After everyone looked at it, they found that it was the garbage truck that appeared at the time of the incident. The windshield at the front of the truck had been smashed.
During this period, the investigation of the case required the garbage truck to be parked in the internal parking lot in the backyard of the Criminal Investigation Detachment.
Meng Qinghan then explained: "Look, everyone, I think that the most critical point of this accident planned by the murderer is also the point that the murderer is least able to grasp, that is, the murderer cannot guarantee that the mad dog will go smoothly at that time.
Jumping into the garbage truck, and regarding this issue, the murderer has actually exposed his clues."
Meng Qinghan then posted another photo, which was a photo of the garbage truck parked in the parking lot of the sanitation department before it crashed.
But everyone can quickly see from the photo that in the photo, the cab glass of this garbage truck was actually smashed by a stone, and the stone also shattered the glass and fell on the floor inside the car.
.
Meng Qinghan explained.
——"Please see, everyone, there is a very coincidental place here, which is where the murderer will inevitably show his flaws in this murder."
——"That is, before the incident, this garbage truck was insured once, and the insurance content was that the cab glass accidentally broke, which is what people often call glass insurance."
——"This is a photo of the on-site inspection by the insurance company's loss assessor. At that time, the car was parked in the parking lot of the sanitation department. According to the description of the accident scene by the loss assessor at that time, it was written that a stone came from next to the sanitation department.
The high-rise building fell and accidentally hit the cab glass of the garbage truck."
"What a coincidence?"
Deputy Director Yang couldn't help but have some doubts about this situation and asked: "At that exact time, a stone fell from the high-rise building next to the sanitation department, and it happened to hit the cab glass of the garbage truck?"
Meng Qinghan responded.
——"When the damage assessor was inspecting the site, he discovered that the monitoring equipment box in the parking lot of the Environmental Sanitation Department accidentally short-circuited and caught fire last night."
——"So without any evidence at the scene, he could only attribute the flying stone to a high-altitude object."
——"But I think this is by no means a simple accident of throwing objects from high altitude, but the murderer deliberately damaged the monitoring equipment box in the parking lot of the Environmental Sanitation Department the night before the incident, and then smashed the garbage truck with rocks.
Cab glass.”
——"The reason why the murderer went to such trouble is that he had actually inspected the scene before. He found that garbage trucks usually smell very bad, so the driver usually has to close the windows when driving."
——"But if the driver really closed the window, the mad dog at that time would definitely not be able to jump into the car."
——"So the murderer would rather risk his own life and sneak into the parking lot of the Sanitation Department in the middle of the night and smash the cab glass of the garbage truck. The purpose is to implement his subsequent plan."
