Sick roommate observation notes

The police’s case-solving process needs to be kept strictly confidential according to requirements, but this restriction is not without loopholes. For example, some police officers will disclose simple content such as the type of case in progress and the purpose of the murderer to family and friends. The degree of leakage is generally within the allowed range.

For a moment, Shen Lu was not sure how much information to reveal to Qin Qiu was in compliance with the regulations, so he hung his fingers on the top of the screen and did not move. While thinking, the taxi stopped slowly, only to hear the driver reminding loudly: "Sir, you The destination has arrived!"

Shen Lu came back to his senses, and after thanking him, he hurriedly got out of the car with his briefcase, moved his injured left arm with some difficulty, took out the key, opened the courtyard door and limped back home.

After he had packed up all his things and cooked the meal, Qin Qiu's profile picture had already dimmed when he turned on the phone again, so he felt even more sorry, and after a moment of pondering, he typed out a line slowly: There is a troublesome case, the deceased died in front of the refrigerator He was stabbed on the ground, but our evidence is limited, and many reasonings are untenable. Now it is difficult to determine who the real murderer is.

After sending the message, he waited for a while, but his roommate did not reply again. Shen Lu went back to the second floor and entered Qin Qiu's room. Sprinkle water on two pots of epiphyllum.

After finishing the simple sprinkling work, Shen Lu put the kettle back to its original position, and instead of leaving Qin Qiu's room immediately, he stood by the window sill and took a quick look around the room.

Qin Qiu's room was too clean and tidy, and all the items were placed in an orderly manner. Although the room did not open the window, it was not cramped, and there was a faint fresh smell. Shen Lu had no doubt that Qin Qiu must be There is OCD, but exactly how severe the symptoms are remains to be seen.

He felt that Qin Qiu's room seemed to have a strange magic power, and the demon hidden in it couldn't help but show its sharp claws at him after he entered the room, and desperately seduced him by his ears——

Check it out, Qin Qiu is not at home now, even if you touch his things, he will not be able to find out.

What does it matter if he finds out?The devil kept making excuses, anyway, he let you come to this room, as long as you are careful enough to restore things, even if there is a slight difference left, you can still say that you touched it by accident, not on purpose I'm going to check it out.

Shen Lu took a deep breath, and then resolutely walked out of the room.

If Qin Qiu is really doing something suspicious, then he will definitely look for clues in an upright manner, and will not break his own moral bottom line to do such sneaky and dirty things!

It's just that Shen Lu's peripheral vision still inevitably caught sight of some things in the room when he left. For example, a USB flash drive on the left side of Qin Qiu's desk made Shen Lu feel very fresh in his memory, because that thing was much more vivid than normal things. The USB flash drive is much larger, and there are a few letters "RTL-SDR" printed on the surface of the USB flash drive, which looks like a rare brand that Shen Lu has never seen before.

Shen Lu shook his head and put the matter of the USB disk behind him, went back to the room and imported the photos collected during the day into the computer, carefully observed and analyzed them one by one, and two hours later, he sat at the desk like this and fell asleep past.

The next morning, after being woken up by the alarm clock, Shen Lu only felt back pain. He walked into the bathroom with the background sound of the alarm clock. After washing, he woke up a little before returning to the desk to turn off the alarm clock. The roommate replied to himself a message at five o'clock in the morning: did he die at home?

The second message was sent at [-]:[-]: Have you ever thought that the failure of the reasoning may be caused by human factors?

After arriving at the police station that day before it was time for work, the black police officer was already sitting in the office to check the documents. Shen Lu couldn't help but came to the police officer and asked, "Deputy Bureau, besides the mistakes in the reasoning process, Under what circumstances will there be human factors that make our reasoning untenable?"

Instead of answering the question directly, the black police officer asked rhetorically, "Where did you get all the evidence you got before reasoning?"

Shen Lu lowered his eyes and thought for a while, and after only a few seconds, he suddenly realized: "So the relevant evidence provider may provide false information, which will cause our reasoning to fail. I'm sorry, it's a very simple question but I don't understand Be careful to ignore it."

The black police officer responded noncommittally, and then raised his head from the file: "What's your purpose in asking this question suddenly?"

"I suggest that Mrs. Green be called to the bureau for re-interrogation. I suspect that some of the information she provided in the report was false." Shen Lu frowned and explained, "Most of the evidence we obtained was through surveillance and other information. From the record, only a small part of the evidence is taken from the confessions of the relevant personnel, and the information provided by Mrs. Green has the greatest impact on our conclusion of the case."

"Your idea is very bold," the black police officer pondered for a moment. "The deceased is Mrs. Green's husband. She is the most affected person in this case. What good is it for her to conceal the correct information from us?"

"Perhaps concealing the real information from us will indeed bring her benefits," Shen Lu pursed his lips and insisted, "There is too little information that can prove that the courier is suspicious, and we have no evidence other than the fingerprints on the doorbell." Nothing, haven't you considered that this matter may have nothing to do with the courier?"

There was silence in the office for a while, and the black police officer sighed heavily: "There is indeed a possibility, but we still need to analyze the interrogation video from last night before making further arrangements. Let's make a decision after everyone comes."

At nine o'clock, the police officers in the office all received an intelligence document related to the courier. After some preparations, everyone sat around the conference room again to observe the video of the interrogation of the courier the night before.In the video, the courier’s expression implied anger, but he didn’t have the panic of ordinary people when he was summoned by the police. He just said in a calm tone to the two police officers who were in charge of interrogating him: “So I’m being arrested by you now, or is it I am innocent, so I can leave now?"

"We didn't arrest you, and you can leave soon, but before that, you need to answer us a few questions," Kelvin said in a gentle manner, "A case happened in the EastTree community today..."

The courier sneered and did not cooperate, and interrupted Kelvin's words: "Do you have an arrest warrant to arrest me? If not, I have the right to leave now. You don't want to keep me here. I understand the law."

"We'll only ask you a few simple questions, but if you don't want to cooperate with us, that's great, we can arrest you for obstructing official duties, it seems that you know something about the law, then you should know that I The charges mentioned are true," Hugh said coldly to the courier, "Answer our questions or be arrested, you choose one."

The courier is a stickler. Hearing this, he just stared at Hugh angrily and didn't answer. After a while, he gritted his teeth and said, "I didn't expect your police to be so despicable. You only know how to threaten good citizens."

"Whether you are a good citizen or not is yet to be discussed," Hugh tapped his pen on the table. Although the courier spoke harshly, it was proof that the other party had no choice but to compromise. "Please answer my question, at 01:30 this afternoon Have you ever been to the EastTree community to deliver packages to residents?"

After a moment of silence in the interrogation room, the voice of the courier reluctantly rang out: "Yes."

“你在01:30到02:30之间曾给701号房派件过吗？”

"Sent it," the courier replied quickly, and then laughed mockingly, "Why, someone died, and you suspect that I did it?"

"You don't need to speculate too much about the case, just answer my question," Hugh warned indifferently, "Can you still recall exactly when you sent it?"

"Around two o'clock, how can I remember the exact time!" The courier's mood became more and more manic, and he raised his hands frantically and smashed the interrogation table with his fists, "Can you do something about personnel, if you can't catch the real The murderer is going to pull me in to take the blame, right?! If you don’t have the ability, you should resign as soon as possible, I know you can’t do it, you can’t do anything!”

The video ended abruptly at this point, and a police officer murmured in surprise, "Is this courier mentally ill?"

"We checked his medical records last night, and there was no information that he had been to the psychiatric department, so he was sent to the psychiatric department after seeing that his mental state was not right," Kelvin now recalled the situation last night and still felt a little bit Speechless, "Later, it was diagnosed that he had a severe mania. At that time, he had a sudden attack, and it was impossible to ask any questions, so the monitoring records disappeared here."

After recording the information on the document, the black police officer raised his head and pointed in the direction of Shen Lu with his chin: "Our little consultant, what do you think?"

"Here is enough, the murder should not be done by him," Shen Lu began to analyze, "Judging from the video, he should have been hurt by the police before, and it may be something like a misjudgment that caused him to have a lot of affection for the police. Great hostility, coupled with the mental illness of mania, he may not be able to control his behavior during the onset of the disease. If we analyze only from these aspects, it is indeed possible to lose control and commit crimes... But what people say when they are emotional It is the least likely to use lies to cover up, not to mention that the courier was ill at the time, and his brain was affected by hormones, so he was even less likely to lie during the interrogation."

"What's more, it's written in the document that he was still dispatching the package in room 55 at 633:59, and sent it to 701 at 701, and then at 935:15, he sent the package to [-], which is two kilometers away from [-]. "Shen Lu said while motioning everyone to turn the documents in their hands to the second page, "In the [-]-minute window, it is impossible for him to complete the murder case in such a short period of time and perfectly deal with the traces of his crime. So there was a very strong alibi."

"Well," the black police officer nodded, and finally agreed to the suggestion made by Shen Lu before nine o'clock, "Call Mrs. Green back, the information she provided before may have some omissions or falsehoods, we have to re- Ask her for all the information she has."

A police officer was ordered to call the phone number left by Mrs. Green. The phone rang for a long time but no one answered it. Two minutes later, the police officer dialed a second time, but this time he was directly prompted " The phone you are calling is off."

"She shouldn't think that someone is making harassing calls to her, right?" Shen Lu said with some trepidation, "Have we reminded her that her phone must be kept open 24 hours a day?"

"We said," the black police officer's complexion suddenly became darker, "find out the address of her friend's house. If she doesn't answer the phone, then we'll go directly and bring her here."
