Chapter 498

Everyone came to the supermarket and called out the monitoring, but unexpectedly found that the monitoring screen just avoided the crime site and only saw the road in front of the door.

Lin Qiupu frowned: "is there such a clever thing? The only surveillance was nothing. "

"I think someone did it deliberately." Chen Shi borrowed a herringbone ladder from the supermarket, and Lin Dongxue came outside. He propped up the ladder and let Lin Dongxue climb up to have a look. Chen Shi held it under him.

Lin Dongxue checked it and said, "some of the dust on the camera has been removed." As she spoke, she photographed it on her cell phone.

Chen Shi looks around, and a fruit shop across the street is also equipped with a monitor. The police used to tune the video. It took half an hour to find a man sneaking up to the door of the supermarket in the middle of the night, pulling out a folded hook and moving the camera head.

The time is on August 6, before the crime.

The man in the picture is dressed in a black sweater, wrapped tightly, and the pixels are so bad that even men and women can't recognize him.

There is no doubt that the man is the murderer. His mind is meticulous and unexpected. He investigates the site of the body throwing in advance to eliminate the hidden danger. Of course, if the murderer were not so careful, he would not have been at large for six consecutive years.

Chen Shi thought, "why does he do this?"

Lin Dongxue went to the supermarket to buy two bottles of drinks and handed one to Chen Shi, "isn't that easy? Don't want to be photographed. "

"But didn't the other monitor shoot him? It means that what he doesn't want to be photographed is not himself, but something else... "

"Something else?"

"The car he drives, or the time of abandoning the body, will take this layer into account, indicating that he predicted that the police would check his alibi evidence, so it seems that he is in our view..." Chen Shi said to himself, his logic brain is moving at full speed, suddenly looked up and said, "the supermarket monitoring remember to copy back!"

Lin Qiupu said, "it's been copied down. It's copied down from supermarkets and fruit shops."

"Lao Peng, Lao Peng, and I will go to the scene again."

Chen Shifeng stormed across the road. Lin Qiupu complained, "who is the team leader?" Lin Dongxue said with a smile, "look how excited he is. Maybe he has an idea!"

Back at the scene, Chen Shi looks at the corpse from various perspectives, just like an artist is examining exquisite art works. He breaks off the eyelids of the dead, moves her arms, and wants to reconfirm the time of death.

Peng sijue said: "don't look at it. The time of death is around 9:00 p.m. on the 7th. You can't get it wrong."

"What about the time of throwing the body?"

"Throwing time..."

"Is there any way to find the time for the body to be thrown?"

"It's very difficult. You can start with the microorganisms and insects on site, but..."

"Those are not accurate enough. I need to be more accurate. The error is within an hour."

Everyone was at a loss. It was a big problem. Chen Shi stared at the corpse and thought for half an hour. He kept talking to himself. There was a policeman smoking nearby. Chen Shi stopped in front of him and looked at him.

The policeman was embarrassed to put out the smoke, but Chen took a deep breath of second-hand smoke and added some nicotine to drive the brain.

Peng sijue said, "don't look at it. You have to take the body back for autopsy."

"Wait, wait..." Chen Shi squatted on the side of the body, crushed some salt particles in his hand, and looked down on the ground. Suddenly he smiled, "the ground is mud!"

"What happened to the earth?"

"When salt touches blood, it melts and seeps into the soil Lao Peng, can you use this as a reference to calculate the time of throwing the corpse? "

Pengsijue thought about it for a moment and said, "a set of experiments is needed to compare it."

"Let's do it. Take the mud away from the scene. I want all the people who are stained with blood and those who are not."

Peng sijue immediately ordered his subordinates to come and start the operation. In order not to damage the original structure of the soil layer, they bought some lunch boxes from nearby convenience stores and shoveled up the soil layer neatly and put it inside.

Eager to get the result, Chen Shi goes directly with Peng sijue by car and leaves Lin Dongxue here.

Lin Qiupu wryly smiled, "this guy, it's true that no madman can survive I'll take you home! "

That night, the members of the technical squadron were watched by Chen Shi to work overtime for the salt penetration test, and they were busy until 10 p.m., of course, waiting for the results to get tomorrow morning.

Chen Shi sat there and thought about the whole case. Suddenly he said, "Lao Peng, can I drink alcohol with antidepressants?"

"It depends."

"Paroxetine."

Peng sijue checked the ingredients of the medicine on the computer and said: "if the medicine is taken together with wine, the blood pressure will rise, accompanied by stomach colic, and the negative effect is relatively large."

"Will it die?"

"It depends on the dosage, but the normal dosage will not die even after drinking alcohol. It will be very uncomfortable at most."

"Oh Should the doctor tell you not to drink

"It's beyond my knowledge."

"I don't know. It's so implicit..." Chen Shi smiled, "by the way, is the anatomic result out in the morning?"

Peng sijue threw a report to him. Chen Shi glanced at it and said, "the internal organs are broken, and the stomach bag is lost? The back of the brain found bits of burnt brick? "

"I think your conjecture at the scene may be right. The murderer opened the abdomen of the deceased to find something. The whole abdomen was scratched. It seems that the murderer didn't have the professional anatomical knowledge, so he took the whole stomach away."

"In this way, the deceased may have swallowed something before he died, which may be an important evidence Do you think the two bodies were made by one person? "

"At night, this one hasn't been dissected. It's not clear. In the morning, although the lethal technique of that one is different, other details are very close. Because I dissected the corpse of the previous years, I'm very impressed."

Chen Shi glanced at the report, "then Cai Yating killed her out of plan. The murderer took her stomach after killing her, and then dressed her in a red dress What did Cai Yating swallow? Can you test it? "

"No damage was found in the esophagus during the dissection. It seems that it's not too big. But if you want to test out what it is, the workload is heavy and it's not easy to get results. It's likely that you won't find anything in a few days. Are you sure?"

"Forget it, no need She chose to swallow it before she died, which shows that it is not easy to damage and relatively small. "

"Will it be The memory card of U disk or mobile phone? "

"Well, it's possible, but we can't see it By the way, if this is the case, it means that Cai Yating was secretly investigating the murderer and knew the identity of TA.

"In fact, Lin team is also looking up Cai Yating's Clues today. Her profession is a reporter of a newspaper. She found everyone's information about the serial killings on the Chinese Valentine's day in her computer. She has been tracking the case."

Chen Shi lamented, "poor girl, maybe she already knows the truth, but she never has the chance to say it."
