Hearing that Liu Li hadn't found the murderer yet, the flight attendant was a little anxious: "How can I find this?" We only have three hours, and once the plane lands, those people will get off the plane, and by then, we won't be able to find the murderer. ￡∝，”

Frowning and thinking for a while, Liu Li said to the flight attendant: "Beauty, call up the surveillance video in the cabin, and start playing it from half an hour before Zheng Zhenze's death, I just asked the doctor, the drug induces coronary heart disease, until the patient dies, it takes about twenty minutes for the slow one, and only a few dozen seconds for the fast one."

The murderer used a certain drug, which induced Zheng Zhenze's coronary heart disease, causing him to die, in order to make this method successful, the murderer must at least contact the deceased, otherwise, how can the murderer drug the deceased? I'll see if anyone had been in contact with Zheng Zhenze before he died of coronary heart disease. ”

After hearing this, the flight attendant skillfully turned on the surveillance video, and in less than two minutes, she adjusted the surveillance screen to half an hour before Zheng Zhenze's death: "Okay, the video has been adjusted, you can watch it." ”

"So fast?" Glancing at the stewardess with some surprise, Liu Li exclaimed: "When you rescued Zheng Zhenze just now, you showed a very professional medical technique, at that time, I thought you were from medical school, but I didn't expect you to be a computer master." ”

"Big officer, you can look away this time, I'm not from medical school, and I'm not a computer whiz." After saying this, the flight attendant paused, and then said something that surprised Liu Li very much: "Actually, we have some origins, I am from the police academy."

After graduating from the police academy, I was assigned to the household registration office of a police station for an internship, and worked all day to apply for household registration and ID cards for others, and after working for less than a month, I found that that life was not suitable for me, so I began to find another way.

Coincidentally, the airline recruited flight attendants, so I came to try it, but I didn't expect to pass the customs at once, before getting on the plane, we flight attendants have undergone special training, including emergency rescue and cabin equipment operation. ”

"I didn't think you're still an all-round expert, amazing." With a look of admiration, Liu Li began to watch the surveillance.

It can be seen from the footage captured by the surveillance video that Zheng Zhenze asked the flight attendant next to Liu Li for a glass of water before he died.

When the stewardess went to serve water to Zheng Zhenze, Shi Xinchuan, who was sitting in the front row, also asked for a glass of boiled water, the stewardess poured two cups of boiled water at the service desk, put them in the tray and sent them to Shi Xinchuan first, and after Shi Xinchuan took one of the glasses of water, the stewardess brought another glass of water to Zheng Zhenze.

Since Zheng Zhenze was sitting in the window seat inside, when the flight attendant walked to Zheng Zhenze's seat, Zhao Xuan next to him helped hand the water cup to Zheng Zhenze inside, Zheng Zhenze said something to Zhao Xuan? As if to thank him, Zheng Zhenze drank the water in the cup.

After drinking the water, Zheng Zhenze got up and returned the water cup to the flight attendant, and at this time, Keku, who was sitting on the left side of the fourth row, happened to see Zheng Zhenze standing up, should the two know each other? After seeing Zheng Zhenze, Koku politely got up and shook hands with him, but the two did not speak, and returned to their seats after shaking hands.

When he sat back in his seat, Zheng Zhenze seemed to be a little sleepy, covered his mouth with his hand and sighed, and then leaned on the seat to rest, at this time, Zhao Xuan got up and went to the bathroom, and when he came back, he sorted out some silk scarves, and then flipped through the magazines from the seat.

After about four or five minutes, Zheng Zhenze's head slowly leaned on Zhao Xuan's shoulder, turned his head to look at Zheng Zhenze on his shoulder, and Zhao Xuan pushed Zheng Zhenze's head back to his seat with his hand.

After pushing Zheng Zhenze's head back, Zhao Xuan continued to look down at the magazine, she didn't notice that about twenty or thirty seconds later, a trace of pain flashed on Zheng Zhenze's face, and then, the corners of Zheng Zhenze's mouth began to bleed, and at the same time, his head continued to lean towards Zhao Xuan's shoulder.

When Zheng Zhenze's head leaned on Zhao Xuan's shoulder again, it was estimated that Zhao Xuan regarded Zheng Zhenze as a pervert, a trace of unhappiness flashed on her face, and after putting down the magazine, she pushed Zheng Zhenze's head back on her shoulder with her hand.

Because he was a little unhappy with Zheng Zhenze's repeated actions of leaning on his shoulder, Zhao Xuan's push this time was a little stronger than last time, and as a result, when Zhao Xuan pushed Zheng Zhenze's head back, he felt that there was something strange on his shoulder, so he looked sideways at his shoulder.

At this time, Zhao Xuan saw that the clothes on her shoulders were stained with blood, so she slowly turned her gaze to Zheng Zhenze next to her.

At this look, Zhao Xuan found that Zheng Zhenze's mouth was overflowing with a lot of blood, and he was stunned for a moment by the scene in front of him, and then, Zhao Xuan screamed in horror on his face, and then stood up with a panicked face.

Seeing this, Liu Li turned off the surveillance video, at this time, he had thoroughly understood the entire process of the case, and screened those who had been in contact with the deceased in his mind, and after that, he fell into deep thought.

"It seems that the murderer should be hidden in Keku, Zhao Xuan, Shi Xinchuan, and this flight attendant, but among the four of them, who is the real murderer?" (To be continued......)
