Detective: On the first day in office, the serial murder case was solved

Chapter 341 Sound analysis , find the crime scene ! ( Please order !)

.Wang Mo’s words rang out slowly in the conference room .

.And listen to Wang Mo’s voice .

.The expressions of everyone became a little excited .

.” Captain Wang , what did you hear ?” Zhao Duoming asked .

.” Can you lock the location of the crime ?”

.The eyes of others in the conference room also stayed on Wang Mo.

.Facing Zhao Duoming’s inquiry , Wang Mo just nodded slowly .

.” There is a slight sound of running water outside the house in the video . ”

.” This sound of running water is not the sound of water flowing in a water pipe , it should be the sound of a river . ”

.Listen to this .

.Zhao Duoming hurriedly looked at the map of Linteng City in front of Wang Mo.

.Linteng City is not small , there are two rivers in the city .

.One is in a suburban location and the other runs through the city .

.After glancing around on the ” Five Five Zero ” map , Zhao Duoming said .

.” That is to say . ”

.” Is the house where the crime happened right by these two rivers ?”

.Wang Mo nodded .

.” Because in the video , the sound of the river is quite faint , very light . ”

.” So the location of the incident should be in an area with slow water flow . ”

.” At the same time . ”

.” At this location , the sound of water can be heard , indicating that it is not a high-rise building , and the location is close to the river . ”

.Listen to Wang Mo’s words .

.Ye Youxue, who also came to watch the map, also nodded .

.At the same time .

.He also hurriedly used a pen to draw several areas on the map .

.But her look .

.Still not easy .

.” But even so , the area we want to search is still very large . ”

.” In the videotape just now , are there any other sounds besides the sound of water ?” Ye Youxue looked at Wang Mo.

.” That’s exactly what I’m going to say next . ”

.And Wang Mo also took a deep breath .

.Then he slowly looked at the crowd .

.” The house in the videotape, in addition to the sound of water , also has the sound of planes passing by . ”

.Listen to this .

.Everyone’s eyes lit up instantly .

.Qiu Yu couldn’t help but speak .

.” There are not many airports in Linteng City , there are only two things in total . ”

.” Since the sound of planes taking off and landing can be heard . ”

.” Then the location must be close to one of the two airports . ”

.” This way . ”

.” The scope of our search can be greatly reduced . ”

.Qiu Yu’s words were not finished yet .

.Ye Youxue on the side interrupted him directly .

.” It’s not that simple . ”

.” It’s not just near the airport that you can hear the sound of planes passing by . ”

.Wang Mo on the side also nodded .

.” That’s right . ”

.” When the altitude of the plane is below 500 meters , the sound of passing planes can be heard on the ground . ”

.” So we can’t just think about the environment around the airport . ”

.Wang Mo looked at Zhao Duoming .

.” You can contact the airport to get the flight records . ”

.” Look at what areas in Linteng City have the conditions to hear the sound of planes . ”

.” That is to say , look at the area within Linteng City, where all the planes pass through at a height of less than 500 meters . ”

.” Use these areas to compare and shrink with the area that two rivers pass through in Linteng . ”

.” Finally . ”

.” It should be possible to find where and where some areas overlap . ”

.”The crime scene is among these locations . ”

.Listen to Wang Mo’s words .

.Everyone nodded thoughtfully .

.Ye Youxue also looked down at the map of Linteng City in front of her .

.At the same time .

.in the conference room .

.Wang Mo’s voice has not stopped .

.” In addition to these two points , there is another key message , I did not hear the sound of the car driving on the video tape . ”

.” Isn’t this normal ?” Zhao Duoming said subconsciously .

.But Ye Youxue instantly understood Wang Mo’s words .

.” Not normal . ” Ye Youxue glanced at Zhao Duoming .

.” It’s not normal . ”

.” You have to know that the videotape is over thirty minutes long . ”

.” In the thirty minutes , there were no cars driving , indicating that the crime scene was definitely not close to the road . ”

.” Even in the early morning , it is impossible for any road in Linteng City to have no vehicles passing by for half an hour . ”

.Listen to Ye Youxue’s words .

.Wang Mo on the side also nodded slowly . �?

.” Yu Xue is right . ”

.” In addition to being close to the river and hearing the sound of planes , the crime scene was far from the road . ”

.”The above three pieces of information should allow us to lock the crime scene in a very small location . ”

.Wang Mo looked at Zhao Duoming .

.” Go to the airport first , get the flight path map , and then start the comparison . ”

.” After the general area is out , I will lead the team to the scene to find the location of the crime one by one . ”

.”The meeting can be dismissed . ”

.” Understood . ”

.” I’ll do it right now . ”

.After Zhao Duoming nodded, he also left the conference room directly .

.The other police officers also left the conference room one by one after Wang Mo’s arrangement .

.However .

.Before Qiu Yu left the conference room , he suddenly stopped .

.” Captain Wang , are there really so many subtle voices hidden in this video tape ? How on earth did you hear them ? ”

.” Why did I watch the tape several times just now and did n’t hear anything . ”

.Listen to Qiu Yu’s voice .

.Wang Mo also smiled .

.” Didn’t Zhao Duoming say that my hearing is much sharper than yours . ”

.” You go to extract the audio from the videotape , then take out the human voice , and clarify the remaining voice , and then you can get the information I said . ”

.” I see . ”

.Qiu Yu also nodded , but the shock 3.1 in his eyes was much more intense .

.He couldn’t help but mutter to himself .

.” It takes so many steps to hear other voices . ”

.”The Wang team just listened to it so directly . ”

.” Is this hearing still human ?”

.And the next second .

.Qiu Yu’s words were not finished yet .

.In the conference room , Wang Mo’s voice sounded .

.” What the hell , go to work . ”

.” Yes !” Qiu Yu hurriedly ran away .

.And in the conference room .

.Wang Mo originally intended to sort out the following information in the current videotape .

.But the door of the conference room was suddenly pushed open .

.A police officer spoke to Wang Mo.

.”The King’s Team . ”

.” There’s something going on over there, chief , please come over . “.
