Chapter 213 Wufu 50 Weapons

Dynasty moves very fast.

When Zheng Xiaoming's parents walked out of the portrait room with their son dizzy, the little fat man was kidnapped by a terrifying young man running in front of him.

Lin Chen held down Zheng Xiaoming's parents and said gently: "They may have some problems and need to communicate privately..."

Xiao Ming's parents were at a loss, so Lin Chen had to invite the two parents to the lounge and make two cups of tea.

Through the glass window, you can see Wang Chao and classmate Xiao Ming face to face, having a dialogue between chickens and ducks. Wang Chao kept talking, but Zheng Xiaoming raised his head blankly, as if I didn't understand what you were talking about.

When the surrounding police officers saw the two of them like this, they all surrounded them curiously.

"Little Dynasty, are you speaking Chinese? Why can't I understand a single word?" a police officer joked next to him, "The kid is going to be dazed by your question."

Dynasty glared at the other party and waved his hand: "You mortals, don't disturb our communication!"

After a while, a very bizarre scene happened. Comrade Zheng Xiaoming opened the dynasty and sat on Comrade Xiao Wang's office chair stuffed with cushions. Facing Comrade Xiao Wang's computer, he didn't panic at all, and he typed a few Chinese characters in a decent manner. Then, a large number of pictures of tall buildings appeared. Zheng Xiaoming looked at one of the buildings, took a piece of paper, wrote down a string of values, then jumped off the chair very obediently, put his hands on his stomach, and looked up at Dynasty again.

"Are you sure?" Wang Dynasty asked.

Xiao Ming nodded.

All the surrounding police officers gathered around, but no one dared to speak.

Chao Dynasty snorted and quickly jumped into the chair and started to operate the computer.

Lin Chen nodded to the two adults in the lounge and walked behind the crowd.

Several police officers stepped aside, Lin Chen stood behind the Dynasty office chair, and the little fat man quickly rubbed against his legs.

Lin Chen had never understood Dynasty's computer interface, the young man typed a large piece of code, then looked back and saw a large group of people surrounding him, and said in horror, "Why are you all surrounding me, I'm so terrifying? !"

"I heard that the murderer tied the murder weapon to a balloon and let it go?" a police officer asked.

"I heard that you are going to retrieve the murder weapon?" another police officer asked.

"We're going to watch you pretend," said the third person.

Wang Dynasty gave a "fuck", and Xing Cong even scratched his scalp: "Speak well, how are you going to find it?"

"The most primitive search method is to pull the net all over the city. We will release the news, determine the final location of the balloon based on the information reported by witnesses, and then judge according to the wind direction of the day. As long as the murder weapon does not fall into the water or is picked up by the aunt to go home and wash it. Cutting vegetables can always be picked up by the masses or searched by us, it’s just a matter of time, right!”

"Nonsense." Xing Conglian was not angry.

"I have a faster method. I can calculate the approximate location of the murder weapon and narrow it down to a range the size of five football fields. If everything goes well, we can find the murder weapon and finish work before dark today!"

"Explain." Xing Conglian said.

"That's right. There is a mathematical model in meteorology that specializes in finding the landing point of the meteorological balloon basket after cutting. We can use this model to determine the possible landing point range of the murder weapon after the balloon released by the murderer explodes at high altitude."

"But how do you determine exactly where the balloon exploded? There are too many possibilities, and it even has a lot to do with the gas charged in the balloon, the weight of the tool, and the material of the balloon's skin." Xing Cong paused and asked; " Are we going to do an experiment?"

"Boss, this is also an original search method, but of course the experiment is to be done." Wang Chao smiled, "Xiao Ming's mother said that the balloons that the murderer gave Xiao Ming are the ones sold in the paradise, so we will buy some later. , tie a heavy object underneath and let it fly, so as to find the final possible location of the murder weapon." The young man said, handing over the value written by Xiao Chuan just now.

"What the hell is this?"

"Oh, my brother just calculated the weight under the balloon, which is the possible weight range of the knife."

Lin Chen looked at the value on the paper: "How did you calculate this?"

"Physics in high school, estimation, just taught my brother about the end of the get out of class, he understands it, amazing!"

Lin Chen frowned and looked at the dynasty suspiciously: "Huh?"

Dynasty was very embarrassed to see: "Uh... I just tried to see if he could understand. In fact, there are not many knives that can be suspended by three balloons and fly, not to mention that they can kill people. They must be lightweight and Sharp, I just asked the forensics department, and they have determined the model of the knife. I just asked my brother to calculate it according to the method of physics, and there is a reference. In fact, at high altitude, these weight errors are negligible. "

"Is it pure dazzling skills?" Lin Chen looked at the little fat man beside Wang Chao's legs, very speechless.

Xing Conglian took the paper handed over by Wang Chao, ignoring my younger brother who was open-mouthed in the young man's mouth, he waved his hand, and summoned the police to arrange an experiment by the Paradise Lake.

The number of people around the dynasty computer, Ulala, was reduced by one-third.

Chao Wang shouted at the back of the leaving police officer: "Remember to install GPS on it!"

Xing Conglian smashed the human head back to the computer and continued: "The experiment can be done, but the wind speed will change every day, how can you finish it all at once."

"Boss, here's another search method I'm going to talk about." Wang Chao said, and he was also a little excited, "Boss, you just said that the difficulty of calculating the final landing point is the time when the balloon explodes at high altitude, right, and it may be There are two explosions and one does not explode, so the trajectory will be very erratic, so how can we calculate the erratic flight trajectory of the balloon?"

Comrade Xiao Wang dragged his tone, and no one paid any attention to him. He had to increase the volume and force himself to ask and answer: "Radar."

"It's impossible." Xing Conglian said, "How could it be possible to detect such a small balloon and accessories, the weather balloon can be detected by radar because its volume is 10-20 times the size of a normal balloon."

"Have you heard of the airport bird detection radar?" Chao asked rhetorically.

"Continue." Xing Nglian stopped talking.

"Radars are all the same. I will not popularize the specific principles. Common moving target radars can detect normal high-speed moving targets, while suppressing fixed useless targets such as buildings, mountains, and clouds. Objects cannot be identified, in order to detect such low-speed flying and small reflection cross-sections through radar, the filtering algorithm needs to be improved, and this algorithm is probably worth more than one billion."

Xing Conglian glanced at him: "Let your brother Achen stand here and listen to you talking nonsense for ten minutes, so there are no conditions to talk about."

Dynasty was instantly deflated and could only say: "Let's go to the Aviation Administration and ask for a copy of the radar data after yesterday's incident. I'll filter it again, but the algorithm is not for sale!"

The time when the murder weapon was found was not too far from what Wang Dynasty had estimated. The police could always find anything they wanted to find, no accident.

Before that, Lin Chen had been sitting in the lounge without saying much, and refused Xing Conglian's arrangement to send him to the hospital. He took off his shoes and sat cross-legged on the sofa, watching everyone in the police station busy.

Zheng Xiaoming was sitting next to him doing his homework. The parents of the little fat man still had to go to work in the afternoon, but because the child himself was really unwilling to go back to school to continue the class, they could only leave him at the police station.

Lin Chen watched the child hold the pencil with his fleshy fist, and try to copy Chinese characters one stroke at a time on the notebook. In fact, this kind of creature is not scary. What is scary is that the genius itself has a strong willpower, which can basically even destroy the earth.

When Xing Conglian came in, Lin Chen was rubbing the child's head, teaching him to study hard in school.

"I thought you would suggest that his parents send the child to the genius class to be with his peers." Xing Conglian brought a cup of warm water and put it in his hand.

"Does Hongjing have such an elementary school?" Lin Chen asked.

"Uh..." Xing Conglian squeezed to his side with a smile, "How about we drive one?"

Lin Chen held the water glass and smiled.

"Your smile is far-fetched, consultant Lin." Xing Conglian said, "It's not like the kind of smile that is so sweet when you see me."

Lin Chen didn't take the joke.

"Since you know the suspect let the murder weapon fly, you have been very few words." Xing Conglian finally said.

"No, I just find it difficult to explain clearly." Lin Chen took a sip of water, "I still think it's an unnecessary thing."

"Um?"

"It's a balloon and a lethal weapon. The target is too big. Would a shrewd killer do this?"

"It's hard to say. It depends on the killer's personality. He's a bit perverted by nature. After killing people, he's very excited and can't wait to dance striptease." Xing Conglian said.

"Yeah, so I also think it's hard to explain this matter." Lin Chen shook his head, "If he was a professional killer, it would be impossible not to know that the police would find his unleashed weapon. He did this purely for the purpose of In order to get rid of the murder weapon as soon as possible, I can understand. But why he didn't tie the last balloon to the murder weapon, but took it away, and finally gave it to Xiao Ming, I really can't understand such a mental state. "

"There is a saying that the murderer should quickly release the evidence related to the murder in batches, but it is not so reasonable to explain why he gave the balloon to Xiaoming here."

Lin Chen really didn't know what to say. In the end, he could only say to Xing Conglian, "I think it must be because I have nothing to do with this murder case, so I have to find some meaning for myself."

"Xing Conglian said seriously: I blame the dynasty for being too capable. I'll go back and beat him."

Hearing this, Zheng Xiaoming, who had been doing his homework, raised his head, looked at Xing Conglian with frightened eyes, and moved his butt to the other side of the stool by the way.

This action was so cute, Xing Conglian walked over and kissed the child's face.

Zheng Xiaoming and Wang Chao are probably similar in some respects. Xing Cong even gave him a kiss. He stood up without a word, walked to the tissue box, took a sheet from it, folded it, and began to carefully wipe the side of his face. He was sentenced to the place where Lian had kissed.

Xing Conglian was stunned.

At this moment, a very excited celebration suddenly broke out outside the lounge.

Lin Chen shuddered, and Xing Conglian looked at each other.

A police officer rushed in and shouted, "Boss, that black bag has been found!"

"So fast?" Xing Conglian stood up, surprised.

"It happened to fall on a lawn in the suburbs, and it was very conspicuous. Xiao Wang calculated the address, contacted the police there, used a metal detector, and found it at once."

About 40 minutes later, the black plastic bag and the murder weapon wrapped in it were sent to the Hongjing Criminal Police Unit, wrapped with ropes and the wreckage of the balloon.

Because the process of finding the knives was so exciting, when the physical evidence was delivered, most of the forensics department and forensic doctors gathered around.

The black plastic bag was carefully dismantled layer by layer, and finally the silver-white, bloody blade was revealed.

Everyone present felt a strange sigh of relief.

Xing Conglian backed away from the stage and said, "Let's get to work, first make sure that this knife is the murder weapon used by the suspect."

The blood samples stained on the blade were taken, and forensic officers began examining the plastic bags and the scotch tape wrapped around them for fingerprints.

When the test results came out, Lin Chen and Xing Conglian were taking Zheng Xiaoming from the dynasty to eat in the cafeteria.

Zheng Xiaoming prefers the braised chicken legs cooked by the canteen chef of the police station. In order to show the good virtues of his brother and brother Gong, Wang Dynasty made an exception to buy five chicken legs from his own small treasury, and gave them all to Zheng Xiaoming. .

Lin Chen looked at Zheng Xiaoming, who had already eaten three whole chicken legs and was about to eat the fourth one.

Xing Cong took a look at the fingerprint report and asked in surprise: "The fingerprints on the tape and the fingerprints on the notebook I brought back from Stancom's office are definitely from the same person?"

"Yes." The policeman nodded and handed the second piece of paper to Xing Conglian: "Then we analyzed the blood sample on the knife and confirmed that it belonged to the victim, Stankang."

Xing Conglian nodded, sighed, and raised his chopsticks to get the chicken thighs into his bowl.

Suddenly, the police officer continued: "At the same time, another set of DNA samples that did not belong to the victim Stankang was found on the murder weapon, and objects matching the second set of DNA samples were found in Curry."

Lin Chen raised his head suddenly, Xing Conglian's chopsticks stopped in mid-air.

"Who is it?"

The police officer handed over the last piece of paper in his hand and said, "My name is Duan Wanshan."
