Chapter 409

When they came to the Meteorological Bureau, the experts made a mathematical model to calculate the starting point of the balloon. After calculation, they gave Chen Shi a rough range. Chen Shi took a map and said, "this is too big, almost a whole area."

Experts said: "no way, the high-altitude air flow is unpredictable, and it is impossible to accurately guess the coordinates, and so many balloons fall on different positions in the city, which means that they are not released at the same time. The span from the first balloon to the last balloon may be a whole night, or within an hour. We calculate all the errors, and that's what we get A large area. "

"Was the wind very turbulent that morning?"

"Quite a mess."

"If you were the murderer, what strategy would you use to release the balloon in order to prevent being traced back?"

"I can't imagine that!" the expert waved his hand repeatedly

"Talk about it!"

So we all talked about it. At first, it was a bit reserved. Later, we began to have no scruples. Some people said that the balloon would leak, and we could spread a layer of glue outside to delay the leak. Some people said that we could put some dry ice in the bag, and the balloon would rise higher and fly farther after the dry ice melted.

Listen to the discussion of these experts, Lin Dongxue said suspiciously, "will the murderer be so smart?"

"I always tend to think that the murderer is extremely intelligent. When a person is eager to get rid of his crime, he will show more intelligence than usual, which is called quick to learn wisdom."

"But there are some murderers, the more flustered they are, the more flaws they show."

Chen Shi laughs, "that kind of murderer, you police can handle, will not come to me, find me naturally are difficult cases."

"That's right."

Chen Shi calls Peng sijue and tells him to check the balloon and bag carefully, and takes a draft of the expert's calculation to him.

Then Chen Shi called Lin Dongxue and drove to the gymnasium where the balloon was lost. He parked the car outside. Lin Dongxue asked curiously, "what are you doing here? The police have taken over the investigation of the balloon theft. We don't need to intervene. "

At the moment, there are several police cars parked outside the venue. Chen Shi looks at his mobile phone and says, "I'll calculate the distance and get off."

Two people get off the car, walk to the warehouse from here, stop for a moment, turn back, and return to the car. It takes a total of 20 minutes. Then Chen Shi drives to the investigation area. Two hours later, he arrives at the area designated by the experts.

He drove on for another four hours. Chen Shi stopped at the roadside, took out the map and said, "four hours is the limit. It's about five o'clock now. If the killer doesn't get the balloon at four o'clock in the morning, he will have to delay the plan of throwing the body."

"But there was no one in the street in the morning."

"The murderer won't release the balloon after daybreak. It's a corpse. It can't even be seen by a street sweeper!" Chen Shi drew a big circle on the map, which was the moving radius of the car from the gymnasium.

"My brother is also checking the traffic control bureau."

"That's just right, both ways."

At this time, pengsijue sent out several wechat messages. He said in the wechat: "the composition of the balloon is complex. 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 killer injected water into it, and the water slowly leaked out during the flight. The ultimate load weight of this kind of balloon is 10kg. Even if there is 3kg of water in it when taking off, I applied the formula you took. At last, I got the approximate range, which is about 10km from the middle section of Hengyang road. "

Chen Shi replied, "thank you!"

Chen Shi took a look at the full circle map. He pointed to the intersection of the two circles and said, "let's start looking here."

After a day's running, it was already afternoon. The two bought fast food along the way to solve the problem of eating. When they arrived at that area, Lin Dongxue said, "did you come here yesterday?"

"Yes, a supermarket selling folding saws is over there..." Chen Shi's vision fell on a high-rise building not far away. "Dynasty Hotel, is it possible that balloons are flying out of here?"

"Go and have a look!"

The two stopped at the parking lot of the hotel and came to the door of the hotel. They saw a group of young people holding a sign with the words "Luo Zuyu I love you" on it. Then three black cars stopped in front of the hotel. A young man in bright clothes walked out accompanied by a bodyguard and a broker. The fans immediately cheered and rushed over. The bodyguard tried to kill them Push away and maintain order on site.

"Come on Luo Zuyu, we believe you!" Some fans shouted slogans and others followed. 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. I'm sick."

Chen Shi is silent and contemplates Luo Zuyu's back.

When they came to the hotel, Lin Dongxue showed his ID card and asked to see the check-in list of these days. However, the hotel said, "I'm sorry, our hotel keeps the guest information strictly confidential and can't disclose it."

Chen Shi thought, it seems that the people who live here are not rich or expensive. Lin Dongxue asked, "can't the police?"

"Unless you have a search document issued by the prosecution."

"Can I see the monitor?"

"No!"

Lin Dongxue is upset for a while. She is going to call Lin Qiupu. Chen Shi presses her arm and says to the counter clerk, "open a room. I want the top one."

"There are VIP rooms above the 20th floor, are you sure?"

"Sure!"

"On the 22nd floor, would you mind? It's full up there. "

Lin Dongxue pulled Chen Shi's arm and whispered, "don't spend this unjust money."

"Nothing."

Chen Shi paid the deposit. The VIP room costs 5000 yuan a day. It's really painful, but in order to investigate the case, he can only bear it.

The waiter accompanied the two people to the room and came to the twenty-two floor. Chen Shi said, "I will not rush into the room first. I will see the structural layout of the whole floor."

The waiter sneered contemptuously. He was used to seeing the common people who came in to experience the experience of beating the swollen face and filling the fat face. Just like Grandma Liu came into the Grand View Garden, when she came in, she looked around and made a fuss, which was really funny.

Chen Shi walked around the corridor. The corridor was covered with thick carpet. Some oil paintings were hung on the wall. There were monitors at both ends. The sound insulation effect was very good. I couldn't hear any movement in the room. Chen Shi reached out to touch the oil paintings on the wall. The waiter reminded: "Sir, this can't be moved."

Chen Shi refers to monitoring, "how about the security here?"

"It's absolutely safe. The third shift in the security room is on duty in turn. If there are any visitors coming in, they must get the consent of the room owner before they can be released."

Chen Shi nodded, and there was a loud noise from somewhere. The three people walked over, and saw a fat man in red pajamas carrying a vase, and he was explaining to the waiter, "how do you do cleaning services? I spend tens of thousands of dollars in a presidential suite. Do you treat consumers like this? I don't know who vomited in this vase. It's disgusting. Go find your manager! "
