Jiang Yiming felt that Mou Liyang was not lying. He thought for a while and asked, "Did Huang Sang leave when you were playing mahjong?"

"It... seems to have left. Yes, he left twice. He said he might have a bad stomach after eating seafood and needed to go to the toilet."

"How long did it take him to go to the bathroom?"

"The first time was very fast, about 5 minutes, and the second time was slower, about 20 minutes."

"Will it take more than an hour?" Jiang Shan lives in Yanggang Village, Jiangbei District, and Huang Shuang lives in Qianjiang Yaju, Jiangnan District. The two places are 10 kilometers apart. Even if Huang Shuang takes a shortcut to kill people on a motorcycle, the minimum round trip is It takes more than 1 hour.

"No, it definitely can't be more than half an hour. After Vice President Huang went to the toilet for the second time, he made three cups of coffee for us to drink. We drank coffee and watched TV. We called it an intermission and waited for us to drink the coffee. After that, Vice President Huang had already come out of the toilet."

"What show are you watching?"

"Watch the Champions League."

"Are you so engrossed in watching that you forget the time?"

"It's impossible. If you don't believe it, you can ask Ye Fengyun and Ji Lan. If I forget the time, it's impossible for them to forget the time too, right?"

"Did you knock on the toilet door when Huang was going to the toilet?"

"No, the three of us are not going to the toilet, why are we knocking on the door? Do you suspect that Vice President Huang killed Jiang Shan?" He asked with a frown.

"Everyone who has anything to do with Jiang Shan is suspected. Do you think Huang Song will kill Jiang Shan?"

"If this happened to me, I might have this idea, but I wouldn't put it into practice, right? After all, killing requires a life."

"It doesn't necessarily mean that you love deeply and hate deeply. Some people will kill someone just because of a few quarrels... However, with your testimony, we can rule out the suspicion of Huang Sang for the time being."

After Jiang Yiming and Zhou Ting came out of Mou Liyang's office, they went to find Ye Fengyun and Ji Lan. Their testimonies were the same as what Mou Liyang said. This was a homicide case, and they would be legally responsible for perjury on behalf of Huang Sang. Jiang Yiming felt that the testimony of the three of them was reliable.

他俩又去前江雅居调阅8月14晚上到15日凌晨的监控录像，监控录像证明：黄送和叶风云、纪蓝、牟利扬于14日20:01走进前江雅居14栋，于15日02:25四个人一起走出来，因此，黄送就有了不在场证明。

"Captain Jiang, judging from all our investigation results so far, Huang Sang had the greatest motive for the murder. Why did he have a perfect alibi?" Zhou Ting asked.

"I also see it this way, but the 20 minutes he spent in the toilet was definitely not enough to complete the murder... But there is a possibility that he took a helicopter to the scene to kill and then flew back, so that there would be enough time to kill. "

"It is almost impossible to fly by helicopter. If he books a helicopter from a wedding company and lets the plane dock on the rooftop of his 14th building, it will make a huge sound. Residents living on the top floor or high-rise buildings will definitely Hearing the sound of the propeller of the plane, as long as we go and visit, his trick will be exposed, and there is a record of the wedding company sending a helicopter, Huang Sui doesn't dare to take this risk, right?"

"Let's go to Huang Sui's home and have a look." Jiang Yiming said.

So Jiang Yiming called Huang Suang and said he would go to his house to see him. He agreed. He said he would go home immediately and whoever gets there first would wait.

When Jiang Yiming and Zhou Ting arrived at Qianjiang Yaju from the criminal investigation team, Huang Sui was already waiting for them with the door open. They took off their shoes and walked into Huang Sui's living room.Jiang Yiming asked where his mahjong room was?Huang Sang took them into the room on the right side of the living room.

The room is about 16 square meters. There is an automatic mahjong table in the middle, with the wires still plugged into the socket. Next to the mahjong table is a rectangular table with tea cups, an electric kettle and a tea tray, as well as four chairs and two Folding chairs and nothing else, the room was clean and tidy, as if it had just been cleaned.

Jiang Yiming asked him where the toilet was?He then took them to see the toilet. The wall of the toilet was equipped with an open glass window. The window sill was about 1.5 meters high. The window was square, about 1.6 meters long and wide, because Huang Xian lived on the highest floor - 26 It's a building, so it's very close to the rooftop. If there's a rope hanging down from the rooftop, people can use the rope to climb up to the rooftop.

Huang Shuang then took them to see the bathroom in the bedroom. Its structure was the same as the toilet in the living room. Huang Shuang said that on the night of playing mahjong on August 8, he went to the toilet in the living room.Zhou Ting carefully checked the window sills of the two toilets and found no trace of anyone climbing on them. Of course, the traces can be washed away, so this doesn't mean anything.

After they came out of Huang Sui's home, they went to the rooftop. The rooftop was very large, surrounded by marble railings on all sides. The railings were about 1.5 meters high and 0.3 meters wide. The middle of the railings was connected by countless columns. The columns were connected to each other. The distance between them is about 15 cm.The two of them checked the railing above Huang Sui's toilet and found no traces of being scratched by hard objects. However, they found fibers attached to the bottom of one of the columns. Zhou Ting took out the evidence bag and used tweezers to pick up the fibers and put them in. .

"Captain Jiang, it seems likely that Huang Sang tied a rope to this column."

"Even if there are traces of being tied up with ropes on the cylinder, we can't explain that he used the 20 minutes while going to the toilet to kill Jiang Shan."

"I still think Huang Sang should have taken some kind of aircraft to leave from the rooftop and fly to Yanggang Village to kill people. Wingsuit flying requires a drop to be carried out, which can be ruled out. The hot air balloon not only requires wind direction, but also the speed is very slow, 20 minutes There is not enough time to go to the scene and kill people, which can be ruled out. Then, the only thing left is the helicopter."

"I think helicopters are also impossible, because flying a helicopter in the middle of the night will wake up the surrounding residents. Once a resident is woken up and he witnesses the helicopter, Huang Sang will be discovered."

"We'd better go visit the residents on the 26th and 25th floors. They may have discovered something unusual."

So they visited and inquired seven residents on the 25th and 26th floors. They all agreed that they found nothing unusual that night. There was a young couple living in Room 7 on the 26th floor. They were watching the Champions League football match and kept seeing 2604 people. They went to bed at 3 o'clock, and they said they heard no unusual noises. Therefore, the possibility that Huang sent a helicopter to the scene to kill people was ruled out.

They then went to the wedding companies that had helicopters to investigate, and all the wedding companies said they had no flights that early in the morning.

"Captain Jiang, I think Huang Sang may have taken a passenger drone to Yanggang Village to kill Jiang Shan."

"Passenger drone? I've never heard of it. Are there such advanced drones?"

"Passenger drones are an innovative product released in 2016. Passengers do not need to fly the aircraft. They only need to set the flight plan and destination in the onboard application, and issue takeoff instructions with one click. Then they can start autonomous driving and reach the designated destination safely. All flight parts are backed up. Even if one of the parts fails, there will be backup to ensure safety. The Dubai Transport Authority in the United Arab Emirates announced that in July 2017, Dubai will become the first city in the world to allow the operation of passenger drones, officially Started trial operation of 'drone taxi' service, using the 'EHang 7' developed in China."

“Is this drone expensive?”

"Of course it is very expensive. A passenger drone costs between 70 and 80 yuan."

"But Huang Zong has spent all his money on Jiang Shan. Where did he get the money to buy such high-tech things?"

"Maybe my investigation of Huang Sang is just the tip of the iceberg. He hid himself deeply just to avoid our investigation."

“Where can I buy this drone?”

“Ehang Drone Company in Guangzhou has it for sale.”

"So, if we go to the company and look up the sales records, can we prove whether Huang Shuang bought a passenger drone?"

"As long as he didn't entrust others to buy it for him, then we can check it. We don't need to go to Guangzhou. We first check Huang Sang's bank account to see if there are any large sums of money. If so, see where the money flows. Where. We can also go to the drone monitoring point at the Yangtze River International Airport to see if there were any drones flying in the city at that time."

"Okay, just do what you say... Today's criminals use high-tech products faster than us. We really have to keep pace with the times, otherwise we will be eliminated."

The two of them went to the bank to investigate Huang Sang's account. However, except for the 200 million yuan given to Jiang Shan, which was the largest expenditure, there were no other major expenditures. This result made them slightly disappointed, which showed that Huang Sang might be using other people. This phenomenon is very common among corrupt officials. In order to avoid being punished by disciplinary inspections, corrupt officials often use other people's ID cards to deposit money in banks.

They went to the drone monitoring point at the airport to investigate. The airport police station set up 90 enhanced control grids in key areas around the airport. A drone monitoring point was set up in each grid, and a drone monitoring point was set up at each point. Set up professional telescopes, professional radio stations, rain protection, sun protection and other equipment and tools.Therefore, when they went to the airport police station to check, they would know whether there were drones flying in the city before and after the incident.

After the police from the airport police station knew their purpose, they turned on the computer (their monitoring data was saved in the computer) to check. Because they had a relatively accurate time, they quickly found the result: at 8:15 on August 01, there was indeed a The UFO took off from Qianjiang Yaju, flew from south to north, landed on a house in Yanggang Village, and flew back to Qianjiang Yaju at 20:01!

Because the lights were dim at night, it could not be seen from the radar screen that it was a passenger drone. However, judging from the size, it should be a large drone, not a drone used for photography.After Jiang Yiming and Zhou Ting saw it, they were very excited: the fox's tail was finally exposed.
