misplaced survival

"Where's the technical department?" Song Zhou looked at Su Mian.

Su Mian nodded in response, projected the computer to the big screen, and said, "During the on-site inspection, the hotel staff said that the surveillance system in the underground restaurant was broken, because it was going to be a holiday for New Year's Day at that time, and no workers could be found to fix it. So we are going to put it off until next year.”

He said, calling out a photo, "But when we climbed to the surveillance camera to check, we found traces of man-made vandalism."

Jiang Xiyan nodded to confirm. After arriving at the sub-bureau, he stayed in the physical evidence room to re-examine the physical evidence clues of the previous case when he was free, trying to catch up with the progress of the team's case as quickly as possible. However, the physical evidence of the casino death case he had yesterday Seen.

"According to the physical evidence from the monitoring video cable and power cable brought back from the scene, the aging is not serious, and there are signs of pulling at both ends of the break, which is indeed man-made."

Su Mian continued, "But the problem is that the monitoring on the whole floor has been destroyed, but the monitoring at the toilet door is good."

Don't you understand how to put clues in front of the police?

He said, calling out the video captured by the surveillance.

The surveillance camera near the toilet door had captured Yi Xin entering the toilet before the incident, and someone followed him in and stayed for a long time before leaving.

About 5 minutes later, shortly after the reporter entered the toilet, he ran out in a panic while making a phone call. This time coincided with the time of calling the police.

Yi Xin entered the toilet and called the police to the informant. Less than 20 minutes later, only the informant and another man entered the crime scene.

But the reporter ran out not long after entering, and did not have the time to commit the crime.

Then the suspicion of another man suddenly increased.

"However..." Su Mian dragged the video back. After the reporter in the screen rushed out of the toilet to call the police, the staff came to confirm the situation.

He froze the frame, pointed to one of the crowd and said, "I didn't know it before, but later I found out that Yan Yu was related to several other persons in charge, so I re-watched the surveillance video and found that Yi Xin was dead. At that time, he was also present at the scene."

In the picture, a man whose height and appearance are very similar to Yan Yu is wearing work clothes, mingling among the crowd, looking calmly at the scene of the crime.

When Guan Haowen's assistant Zeng Zhi was interrogated before, he also mentioned this matter.

But Su Mian didn't close the coffin to conclude that the murderer was Yan Yu, because during the time between the deceased entering the crime scene and confirming the accident, the surveillance did not capture Yan Yu entering the scene.

On this point, Song Zhou agreed. They did not rule out Yan Yu's suspicion of committing the crime, but before finding evidence, they would not assert that he led other cases because of their suspicion.

But this video is the last clue they have about Yan Yu's appearance.

He immediately looked at Lu Nanhuai, "Doctor Lu, is there anything new in the autopsy report of the deceased?"

Lu Nanhuai pursed his lips and nodded, and said slowly: "The forensic doctor conducted an autopsy on the deceased before and determined that the real cause of death was the rupture of the carotid artery and radial artery of the wrist by external force. But it was not the killing with playing cards as rumored. fruit knife."

After killing the deceased, the murderer stuck a playing card in each of his wounds, so there was a rumor of "playing card killing" among the onlookers.

But they took samples from the wound of the deceased and found some fruit acid in the blood, so the murder weapon was a fruit knife, but the murderer took it away from the scene.

And the physical evidence found two complete fingerprints on the playing cards.

Lu Nanhuai: "During the autopsy, the forensic doctor found that the contents of the deceased's stomach were extremely acidic, and the examination found that there were components of fermented yogurt and capsaicin, as well as undigested potato chips and fried chicken."

So they suspected that the deceased should have eaten spicy food, and then used milk to relieve the spicy food.

But if it was only for this reason, the contents of the deceased's stomach would not be so sour, so he and Wu Yi continued to investigate.

"We contacted the family members of the deceased. The deceased had a long-term history of stomach problems and hyperacidity, and usually would not take the initiative to eat dairy products." Lu Nanhuai took out the medical records of the deceased, which can also be used as evidence.

Patients with hyperacidity can drink some milk to supplement nutrition, but it is best not to drink it cold or on an empty stomach.

In Yi Xin's case, it would be fine to drink a sip or two of milk, but judging from the contents of his stomach, what he drank should be yogurt, and he drank a lot.

It is spicy and yogurt. For a person like him who needs to take medicine for a long time, he will react soon, and the vomiting and diarrhea are mild.

In this way, the murderer can guarantee that the deceased will go to the toilet.

"The deceased ate chili first, and then used dairy products to relieve the heat, so why did he eat chili? Didn't he know that he couldn't eat these?" Song Zhou asked a question.

Lin Yue followed the captain's words and explained: "We went to the deceased's office and asked his family members. The deceased liked to eat snacks very much and almost never left his hands. So we guessed that the murderer probably changed the snacks of the deceased. But it can be done Seeing this and understanding the habits of the dead should be the people around him."

In addition, the deceased did not respond much to the struggle during his lifetime, and the autopsy report of the forensic doctor also stated that his pupils were dilated and he was in a state of surprise, so they speculated that this should be an acquaintance who committed the crime.

When they went to Yi Xin's office, the table and drawers were full of snacks.

According to the memories of the cleaning aunt, Yi Xin didn't drink a sip of water all day, and she used drinks to quench her thirst. She cleaned here every day, and the trash can was full of snack bags, which were overflowing.

Having long-term stomach problems but not eating well, he only ate these unnutritious and harmful things, which made Yi Xin obese and his stomach problems became more and more serious.

The deceased's parents died young, and his wife also died of illness two years ago, leaving only a married younger sister in the family.

When questioned by the police, the deceased's younger sister said that the deceased used to have a well-proportioned figure, but later he did not control his weight and ate too much, so he never lost weight.

"Do you know what enemies your brother has?" the policeman asked at the time.

The deceased's sister shook her head and denied, "My brother is kind-hearted and fat. He behaves well and is an optimist. I haven't heard of any enemies."

She also said, "My brother is very kind to me and has always taken care of me. My brother bought the house I got married with. My husband failed to start a business a few years ago, and it was my brother who helped us pay off the debt. He is really nice! So Trouble police officers, you must help us catch the murderer!"

In addition to relatives, the police also investigated the deceased's friends and hotel staff. Everyone said that the deceased had a good personality, was open-minded, and was generous in his actions, and did not take the initiative to provoke any enemies.

However, it was illegal for the deceased to gather crowds to gamble during his lifetime. He gave generously to his family and friends, but his actions really endangered the society.

Because of Yi Xin's case, the police also investigated the hotel and found nothing wrong. As the hotel staff said, this is a place to eat.

But the police always feel that there is something wrong. Now it seems that this is a group of organized and disciplined gambling gangs.

"So in this case, we were still guided." Just now Song Zhou was taking notes on the whiteboard while listening.

According to the investigation results of various departments, this case has a clear direction, but this guidance is contrary to the case itself. It is obvious that someone deliberately threw clues to them.

Jiang Xiyan nodded in agreement, "The physical evidence found two clear fingerprints based on the poker cards on the deceased's body, thus pinpointing a suspect, that is, Tan Xia, but the range of suspects we discussed just now is acquaintances who committed the crime."

This Tan Xia had a criminal record in the Public Security Bureau and was a repeat offender of theft.They imported the fingerprints into the database and checked them out, and then compared his footprints, which matched the footprints on the compartment door, and he himself was the man who followed the deceased into the toilet.

Almost all clues point to this person, but the evidence is too obvious.

The police searched for Tan Xia's home address. Unexpectedly, Tan Xia was wandering downstairs at that time. When he was brought back to the police station, he was still confused.

They interrogated Tan Xia overnight, but he kept denying that he had killed anyone.

"Yes, I admit, I went into that toilet, but I just want to plead with Boss Yi, I didn't kill anyone!"

"plead?"

Tan Xia hesitated for a long time, but compared to the murder, what he did was nothing worth mentioning, so he confessed honestly: "I...I owed a sum of money to Boss Yi, and I just wanted to ask him for more money that day. Give me a few days of grace. As a result, after I went in, Boss Yi kept talking harshly to me, and I was so angry that I kicked the door a few times, and then left."

Policeman: "That means, when you left, the deceased was still alive?"

"Yes, he still scolded me." Tan Xia only felt aggrieved.

Usually he can't get in touch with Boss Yi, so he can only look for him at this time.

The police showed evidence, "What happened to the fingerprints on the playing cards?"

Tan Xia scratched his head, hesitantly said: "How do I know this? Could it be because I was playing cards there that night, and the cards were taken away by others?"

Because the suspicion of Tan Xia could not be ruled out, the police later temporarily detained him.

But if what Tan Xia said is correct, how did the murderer manage to feed Yi Xin chili peppers in a short period of time, then hand him dairy products to relieve the spiciness, and then go back to the toilet to ambush and commit crimes?

So this case is not only committed by acquaintances, but there may be more than one murderer.

"So the question is, where did the murderer hide before committing the crime, and where did he leave after committing the crime?" Song Zhou guided.

The main purpose of this meeting is to review the whole story of Yi Xin and Zhang Wei's case, so as to facilitate the development of future work.

"Besides the toilet cubicle, there is only one place where people can hide, the ventilation duct above the toilet." Bai Ya continued, "We went back to the murder scene again, climbed up the ventilation duct of the toilet, and found the murder weapon inside, as well as someone The traces of staying. Following the traces, we found the office of Zhang Wei, another person in charge of the casino."

And Zhang Wei just met the suspect conditions they deduced before, and the degree of suspiciousness skyrocketed.

Lin Yue said in a deep voice: "But when we were about to investigate Zhang Wei, we received a call from the marine police. Several children playing at the beach found the body washed up on the beach."

The corpse was highly decomposed and looked like a giant, beyond recognition. The entire abdomen was swollen and might explode at any time. It was the sixth day they were dealing with Yi Xin's case.
