Everyone came to the supermarket and called up the monitoring, but unexpectedly found that the monitoring screen happened to avoid the scene of the crime, and only the road in front of the door could be seen.
Lin Qiupu frowned and said, "Is there such a coincidence? The only surveillance camera did not capture anything."
"I think someone did it deliberately." Chen Shi borrowed a herringbone ladder from the supermarket and went outside with Lin Dongxue. He propped up the ladder and let Lin Dongxue climb up to take a look. Chen Shi was holding it underneath.
Lin Dongxue checked it again and said, "The dust on the camera's head has been wiped off a bit." As she said, she took the photo with her mobile phone.
Chen Shi looked around. A fruit shop across the street also installed surveillance. The police went to watch the video. It took half an hour to find someone sneaking up to the supermarket door late at night and pulled out a foldable. The hook of the camera moved the camera head.
The time display is August 6, before the incident.
The person on the screen is wearing a black sweater, which is tightly wrapped, and the pixels are so poor that even men and women cannot be distinguished.
There was no doubt that the man was the murderer. His careful thoughts were unexpected. He surveyed the place where the body was thrown beforehand and eliminated the hidden dangers. Of course, if the murderer is not so cautious, it is impossible to get away with justice for six consecutive years.
Chen Shi thought, "Why would he do this?"
Lin Dongxue went to the supermarket to buy two bottles of drinks, and handed one of them to Chen Shi, "Isn't that simple? I don't want to be photographed."
"But didn't the other surveillance camera photograph him? It means that he didn't want to be photographed not himself, but something else..."
"Something else?"
"The car he drove, or the time he abandoned his body, would take this into account, indicating that he predicted that the police would investigate his alibi. From this point of view, he is within our field of vision..." Chen Shi said to himself Yu Yu, his logical brain was operating at full speed, and suddenly he looked up and said, "Remember to copy back the monitor of the supermarket!"
Lin Qiupu said: "It's done. The supermarket and the fruit shop are all done."
"Lao Peng, Lao Peng, and I will go down the scene again."
Chen Shifeng crossed the road fiercely, Lin Qiupu complained: "Who is the captain anyway?" Lin Dongxue smiled and said, "Looking at him so excited, he should have an idea!"
Back at the scene, Chen Shi observed the corpse from all angles, as if an artist was examining a beautiful artwork. He opened the deceased’s eyelids and moved her arm to reconfirm the time of death.
Peng Sijue said: "Don't look at it, the time of death is around nine o'clock in the evening on the 7th, you can't make a mistake."
"So what about the time to toss the body?"
"Time to toss the body..."
"Is there a way to figure out the time to throw the body?"
"This is difficult. You can start with the microorganisms and insects on site, but..."
"Those are not accurate enough, I need to be more precise, the error is within an hour."
Everyone looked at a loss. This is really a big problem. Chen Shi stared at the corpse and thought. He stood for half an hour and talked to himself non-stop. A policeman smoked a cigarette nearby, and Chen Shi stopped at him. Before, I glanced at him.
The policeman embarrassedly prepared to put out the cigarette, but Chen Shi took a deep breath of secondhand smoke and added a bit of nicotine to drive his brain.
Peng Sijue said: "Don't look at it, you have to take the corpse back for autopsy."
"Wait, wait..." Chen Shi squatted on the edge of the corpse, crushed some salt particles and looked at it on his hands. He squatted down to observe the ground and suddenly smiled, "The ground is mud!"
"What's wrong with the dirt?"
"The salt touches the blood, melts, and seeps into the soil... Lao Peng, can you use this as a reference to calculate the time to throw the body?"
Peng Sijue considered it for a while and said: "A set of experiments is needed to compare."
"Then do it, take away the dirt from the scene, I want it all with and without blood."
Peng Sijue immediately ordered his subordinates to come over and start the operation. In order not to damage the original structure of the soil, they bought some lunch boxes from a nearby convenience store and shoveled the soil neatly into them.
Anxious to get the result, Chen Shi went directly with Peng Sijue in the car and left Lin Dongxue here.
Lin Qiupu smiled bitterly, "This guy, he's really not crazy and he won't survive... I'll take you home!"
That night, the members of the technical squadron were stared at by Chen Shi to work overtime to conduct salt penetration tests. They were busy until ten o'clock in the evening. Of course, they had to wait for the results to get tomorrow morning.
Chen Shi sat there to supervise and thought about the whole case. He suddenly said: "Lao Peng, can I drink alcohol with antidepressants?"
"It depends on which one."
"Paroxetine."
Peng Sijue checked the ingredients of this medicine on the computer and said: “If this medicine is taken with alcohol, blood pressure will rise, accompanied by stomach cramps, and the negative effects will be greater.”
"Will it die?"
"It depends on the dose, but the normal dose will not die even if you drink alcohol, at most it will be uncomfortable."
"Oh... should the doctor tell you not to drink bars?"
"This is beyond my scope."
"'I don't know' is so implicit..." Chen Shi smiled, "By the way, have the results of the anatomy in the morning come out?"
Peng Sijue threw a report to him, and Chen Shi glanced at him and said, "The internal organs are broken and the stomach pouch is missing? Burnt brick debris is found in the back of his head?"
Peng Sijue said: "I think your speculation at the scene may be correct. The murderer opened the deceased’s abdomen to find something. The entire abdominal cavity was poked. It seems that the murderer did not have professional knowledge of anatomy, so he took the entire stomach away. Up."
"In this way, the deceased may have swallowed something before death, perhaps an important exhibit... Do you think these two corpses were made by one person?"
"This one has not been dissected in the evening. It is not clear. Although the killing method of the one in the morning is different, the other details are very close. Because the corpse from the previous few years was also dissected by me, I am very impressed."
Chen Shi glanced at the report, "Then Cai Yating was an unplanned murder. After killing her, the murderer took away her stomach, and then put her in a red dress for a while... What exactly Cai Yating swallowed can be tested. A moment?"
"The esophagus was not damaged during the autopsy process. It does not seem to be too big a thing, but if you want to test what it is, the workload is heavy and it is not easy to produce results. It is very likely that you will get nothing in a few days. You are sure ?"
"Forget it, no need... She chose to swallow something in her belly before she died, indicating that this thing is not easy to damage and is relatively small."
"Could it be... a USB flash drive or a cell phone memory card?"
"Well, it is possible, but unfortunately we shouldn'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 the TA, so she was silenced."
“In fact, Team Lin is also investigating Cai Yating’s clues today. Her profession is a reporter for a newspaper. She found information about the Tanabata serial homicide on the computer where she lives. She has indeed been tracking this case.”
Chen Shi sighed with regret, "Poor girl, maybe she already knows the truth, but she will never have a chance to tell it."
