The two came to the Meteorological Bureau. The expert made a mathematical model to calculate the starting point of the balloon. After calculation, Chen Shi gave an approximate range. Chen Shi took a look at the map and said, "This is too big, it's almost An entire district."
Experts said: "There is no way, the high air flow is unpredictable, it is impossible to accurately infer the coordinates, and so many balloons fall in different locations in the city, which means that they are not released at the same time. The span from the first balloon to the last balloon. It may be a whole night, or it may be within an hour. We count the errors in all statistics, and the result is such a large range."
"Did the wind direction be messy that morning?"
"Quite messy."
"If you were a murderer, in order to prevent being traced back, what strategy would you use to release the balloon?"
The expert waved his hand again and again and said, "I can't imagine this!"
"Let's discuss it!"
So everyone talked about it. At first they were a little reserved, but then they started to have no scruples. Some people said that the balloon would leak. You can put a layer of glue on the outside to delay the leak. Others said you can put some dry ice in the bag. After the dry ice melts, the balloon will rise and fly farther.
Listening to the discussions of these experts, Lin Dongxue said suspiciously: "Will the murderer be so smart?"
"I have always tended to assume that the murderer is extremely clever. When a person is eager to get rid of crime, he will show more than usual IQ. This is called wit."
"But there are also some murderers, the more they panic, the more flaws they reveal."
Chen Shi smiled, "You police can handle that kind of murderer, and you won't find me. Naturally, those who find me are difficult cases."
"makes sense."
Chen Shi called Peng Sijue and asked him to double-check what was on the balloon and bag, and took a copy of the expert's calculation draft to him.
Then Chen Shi called to Lin Dongxue, drove the car to the stadium where the balloon was missing, and parked the car outside. Lin Dongxue curiously asked, "Why are you here? The police of the balloon theft case has already taken over the investigation and we don't need to intervene."
At this moment, there were indeed a few police cars parked outside the stadium. Chen Shi looked at his phone and said, "I will calculate the distance and get off."
The two got off the car, walked from here to the warehouse, stayed for a while, turned back, and returned to the car. It took a total of 20 minutes. Then Chen Shi drove into the investigation area. Two hours later, he arrived at the area designated by the expert.
He drove forward again. After driving for four hours, Chen Shi stopped on the roadside and took out a map and said, “Four hours is the limit. , The murderer’s corpse throwing plan had to be delayed by one day."
"But there are no people on the street early in the morning."
"The murderer won't release the balloon after dawn. That's a corpse. It won't work if a street sweeper sees it!" Chen Shi drew a large circle on the map, which was exactly the moving radius of the car from the stadium.
"My brother is also checking the surveillance of the Traffic Management Bureau."
"That's right, two-pronged approach."
At this time, Peng Sijue sent out a few WeChat messages. He said in the WeChat: "The composition of the balloon is complicated. It may be air pollutants from high altitude, but a small hole was found at the bottom of each bag. It is suspected that the murderer had injected it into it. Water, the water leaks out slowly during the flight. The ultimate load weight of this balloon is ten kilograms. Even if there are three kilograms of water in it when taking off, I applied the formula you photographed and finally got this approximate range. The middle section of the road radiates about ten kilometers outward."
Chen Shi replied: "Thanks!"
The scope has been shortened by half again. Chen Shi glanced at the circled map, pointing his finger at the intersection of the two circles, and said: "Let's start checking here!"
After driving for a day, it was already afternoon. The two bought fast food to solve the problem of eating. After arriving in that area, Lin Dongxue said, "Did you come here yesterday?"
"Yes, there is a supermarket selling folding saws..." Chen Shi's gaze fell on a tall building not far away, "Dynasty Hotel, is it possible that the balloon really flew out from here?"
"Go and see!"
The two parked in the hotel’s parking lot and came to the entrance of the hotel. They saw a group of young people holding signs in their hands that read "Luo Zuyu, I love you" and so on. At this time, three black cars stopped in front of the hotel. , A well-dressed young man walked out accompanied by a bodyguard and an agent. The fans immediately cheered over and the bodyguard pushed them away desperately to maintain order on the scene.
"Come on, Luo Zuyu, we believe in you!" Some of the fans shouted slogans, and others followed suit. Luo Zuyu nodded to everyone and walked into the hotel.
"Wow, it's really him!" Lin Dongxue said, "It's far worse than the image on TV. It looks sickly."
Chen Shi was silent, staring at Luo Zuyu's back in thought.
When the two came to the hotel, Lin Dongxue showed his credentials and asked to see the check-in list for the past few days, but the hotel said: "I'm sorry, our store keeps the information of guests strictly confidential, and we absolutely cannot disclose it."
Chen Shixin thought, it seems that the people who live here are either rich or rich. Lin Dongxue asked, "Can't the police also do it?"
"Unless you have search documents issued by the prosecutors."
"Can the monitor be watched?"
"Can not!"
Lin Dongxue was annoyed for a while and was about to call Lin Qiupu. Chen Shi pressed her arm and said to the counter staff: "Open a room, I want the highest level."
"There are VIP rooms above the 20th floor, are you sure?"
"Sure!"
"Do you think the 22nd floor is okay? Going up will be full."
Lin Dongxue pulled Chen Shi's arm and whispered, "Don't spend this wronged money."
"fine."
Chen Shi paid a deposit, and the VIP room cost five thousand yuan a day, which was really painful, but for the investigation of the case, he had to endure it.
The waiter escorted the two to the room and came to the 22nd floor. Chen Shi said, "Don't enter the room in a hurry. Let me take a look at the structural layout of the entire floor."
The waiter sneered contemptuously. He was accustomed to seeing the civilians who came in with swollen faces and filled up fat, just like Grandma Liu entered the Grand View Garden. When he came in, he looked around and made a fuss. It was ridiculous.
Chen Shi walked around the corridor. The corridor was covered with thick carpets. There were some oil paintings on the walls. There were monitors on both ends. The sound insulation effect was very good. He could not hear any movement in the room, so Chen Shi stretched out his hand. Touching the oil painting on the wall, the waiter reminded: "Sir, this can't be moved."
Chen Shi pointed to surveillance, "How about the security here?"
"It is foolproof. The security room is on duty in three shifts. If foreign guests want to come in, they must obtain the consent of the room owner before they can be released."
Chen Shi nodded. At this moment, there was a loud noise from somewhere. The three of them walked over and saw a fat man in red pajamas carrying a vase. He was arguing with the waiter: "How do you do the cleaning service? I spend tens of thousands of dollars. Living in a presidential suite, do you treat consumers like this? Look at this vase. I don’t know who is vomiting. It's disgusting. Go and find your manager!"
