Guide to Domestic Police Dogs

"Is the case very difficult?" Zhang Jing came over with the dumplings and put them on the table, the steaming aroma filled the room, "I will offer incense to your father when I come back."

Gu Nianyi raised the incense stick over his head, bowed to his father's portrait, then inserted the incense into the incense burner, and sighed deeply.

"I can't say it's difficult." Gu Nianyi sat down at the table, started to eat, and raised his head halfway through eating, "I just think it's annoying..."

"Is your foot better?" Zhang Jing didn't ask about the case anymore, but asked about his body.

"Yeah." Gu Nianyi nodded, "It's okay."

"Take a day in a few days to check again." Zhang Jing said, "If you don't want me to accompany you, go by yourself. You still need to check."

"Got it." Gu Nianyi finished a small serving of hot dumplings in 3 minutes, wiped his mouth with a tissue, "I'm going to sleep."

"Sit down and digest food." Zhang Jing suggested, "It's just right, wash the dishes."

Gu Nianyi had no objection, stood up with the bowl to wash, and went into the kitchen humming a little tune.

Zhang Jing couldn't sit still either, and went to the kitchen to see two bowls in his hands.Gu Nianyi's hands were full of foam, and while washing, he said, "I hope my father will protect me, and quickly end this case."

"Father can't protect you, you still have to rely on yourself at critical times." Zhang Jing stood beside him, staring at the bowl in his hand, "You, sometimes you are too stubborn..."

Zhang Jing is a very gentle mother, at least in Gu Nianyi's opinion, since the years after her father's death, she has been surprisingly strong and calm.Back then, Gu Nianyi wanted to take the college entrance examination, and he wanted to become a drug police officer in the southern region far away from home, and he wanted to apply for a major in drug control.Relatives and neighbors in the family are all trying to persuade Zhang Jing, but Zhang Jing is the only one who doesn't care.

"Just be safe." Zhang Jing said at the time, "When the child grows up, his whole life will be so long. It's better to be afraid than to have regrets."

But Gu Nianyi finally stayed. After thinking about it, he shouldn't be so selfish.At that time, after Gu Qiuchang sacrificed, he was posthumously awarded the second-level hero model of the public security, and his police number was sealed up. Gu Nianyi could have been admitted to the police academy by exception, but he had outstanding grades in the academy and had always shown amazing talent for insight. A few police uncles who watched him grow up and gave him a lot of help. Once his father’s comrades in arms cared about him even if he went to all parts of the country, and Wang Cheng always regarded him as his own. When he really entered the police department , Let Gu Qiuchang's alarm signal be restarted and passed on to him.

He remembered that when he put on that police uniform, Zhang Jing insisted on making him straighten his back and take a short video for him to post on Moments. That was the only time in the past few years that he saw her shed tears.

It's been so many years in a flash.

He looks good, adapted to the life of the police force, and can take care of his mother. Whenever a difficult case arises, he will come back to talk to Gu Qiuchang. Make a show in front of the grave.

"Hurry up and give me your dream." Before going to bed, Gu Nianyi clasped his hands together and bowed to the black and white photo.

……

Gu Nianyi woke up at midnight, very disappointed, there was nothing in the dream.

He could only rush to the bureau after finishing the breakfast prepared by Zhang Jing.

When I arrived at the office, it was still early, and I saw Gu Xinxin eating buns.

"Morning, eat and eat." Gu Nianyi knocked on the table and said, "I will upload the statement of the two of you yesterday, I will use it."

"Hmm." Gu Xinxin patted his chest, choking and said, "Let me finish my breakfast..."

Gu Nianyi took out his usual recording book, saw that there was still a cup of coffee on his desk, and asked, "Whose is this?"

"Here you are." Gu Xinxin said, "It was originally given to me by Dr. Xu. He is going to work on the calculation system today. He came early in the morning. I suspect that he didn't come home."

When Gu Nianyi heard Xu Luo's name, he picked it up and took a sip unceremoniously, and said in a strange way: "Doctor Xu? Why did he invite you to drink coffee again?"

"Yesterday he invited the whole group to drink milk tea, but today he invited me to drink coffee." Gu Xinxin rubbed his stomach, and his tone was a bit regretful, "But I can't drink it during my menstrual period, it hurts to death..."

"That's right." Gu Nianyi smiled and showed her that he had already drank a third of his coffee in one go, "Drink more hot water."

"Get out!" Gu Xinxin pointed outside, "That's right, Sister Tian came to you early in the morning, and the physical evidence center seems to have adjusted the monitoring. Waiting for you and Team Wang to go to see in the morning, is Team Wang on a business trip? Early in the morning There is no luggage at my feet, so I am in such a hurry."

"Well, it seems to be going to Hualin." Gu Nianyi said.

"What are you doing in Hualin?" Gu Xinxin swallowed the last bite of the bun, "He's gone, and the case on Bar Street will be shelved again."

Gu Nianyi didn't speak, put down the coffee cup, smacked his lips, and said: "I'll go there first, remember to finish sorting out the confession for me."

"Hmm." Gu Xinxin shook his hand.

Although his father didn't have a dream last night, he thought about it and found that he still wanted to start with the surveillance video. The murderer was probably hiding in a special way.

Gu Nianyi flipped through yesterday's on-site investigation report again, and found that there was no evidence of discarding in the sewer septic tank dump, and in the final analysis, nothing was found.Instead, there was an extra report on the table, which was a reference for the police force made yesterday by Xu Luo based on the current evidence to analyze the psychology of criminals.

Gu Nianyi walked across the building with his legs, flipping through the paper with shaking hands, remembering the conversation with him yesterday before he got off work.

Is this person really kicked out without sleep?

Xu Luo and his thoughts are actually similar. The murderer is likely to be plain and unobtrusive, and he is a very convenient person to enter and exit the hospital. He understands the hospital's terrain and on-duty system.Furthermore, this person is a very "ordinary" person for the hospital, and he doesn't need to deliberately pretend, because this is his daily routine.

What Gu Nianyi thought before going to bed last night was that if there was a murder related to him last night, and he saw Gu Xinxin in his office in the morning, he would not feel surprised why she was here.

If Xu Luo appeared in his office in the morning, he would focus all his suspicions on Xu Luo, because Xu Luo was an outsider, the suspicion would multiply and become more conspicuous.

Therefore, on a rare morning, if the murderer walks through the employee aisle, even if he is holding a chair in his hand, no one will think it is a violation of peace.

Xu Luo also mentioned that although many things seem to be coincidences, such as the rain washing away the traces, such as the disappearing surveillance, it can also show that the murderer is well prepared for the situation and his proficiency in handling the scene is not like the first one. One crime.

He mentioned that Lin Song, another surveyor in the Bureau, who once participated in the detection of eleven serial headless corpses in Massachusetts, USA, stitched up the corpses that he didn't want to stitch continuously in his life, he consulted the deceased Lin Song felt that the six stab wounds were done in a panic and haste.

Xu Luo decided that it was "completely inconsistent" with his character and consciousness of calmly handling the scene.

Combining their previous guesses on the premise of "torturing the murderer"...

He may have tortured the other person many times, and the stabbing afterward was more like a whim because of its roughness.Whether he is being tortured or has been tortured to death, he can completely pretend that the other party is self-abusing or committing suicide instead of letting himself fall into a passive state.

If it has not been found elsewhere, based on the current search progress and the suspect's psychology, there is a high probability that he has not transferred the murder weapon. However, since he may know that the police have expanded the search area, there may be a possibility that he will take The murder weapon was placed where they had already checked, creating the illusion of continuing to hide.

So to sum up, Xu Luo suggested that the police conduct a second or even third search of the location where the murder weapon may have been hidden before.

Gu Nianyi bit the straw in his mouth, flattened the straw, raised his hand and threw it into the trash can next to him.

He felt that Xu Luo's whole nonsense was nonsense, but there were a few points that he could really think about.

To be honest, many of the criminal cases in the 90//[-]s were unsolved cases at that time because of the backwardness of criminal investigation technology and the unpopularity of surveillance cameras and DNA technology, and it was quite difficult to solve them.But today is no longer what it used to be. The convenience brought by technology has made crime nowhere to hide. However, if this is simple and straightforward, it seems that a case that can be solved tomorrow will make it more difficult for them.

The police need to make inferences based on current evidence, but this is a gradual process based on their daily accumulation and experience.

Only part of Xu Luo's judgment coincides with his. How should I put it, it's something, but it's too illusory. What's the basis for guessing?What about logic?What's the point of wasting police force?That's why he couldn't understand why the Bureau wanted to implement something like a "calculation system" that cost lives and money.

The technicians of their great physical evidence identification center took out all the surveillance videos from the corridor connecting the staff passage to the locker room between [-]:[-] and [-]:[-] in the night, and they wanted to rummage through them one by one for the current valuable clues , Everyone who passes the screen has passed face recognition technology, and no matter how unclear the face is, the names of the people must be aligned.And there were many people in the blurry video during that time, including nurses, doctors, and nurses in the hospital department, as well as security guards, canteens, logistics, and cleaners.There were even several people walking back and forth carrying a few chairs and tables, carrying suitcases, and large garbage bags abound.

So far, it seems that it can basically be matched.

Gu Nianyi looked at the video, waved his long legs, stroking his hair with his hands, and said irritably, "Because of the surveillance blind spots, even if these people may have time to commit crimes, what is their motive? Isn't it strange why a university professor who is thousands of miles away has murderous intentions? To seek wealth? To seek power?"

"You can't always analyze problems based on motives, you should pay more attention to evidence." Technical Xiaowang looked at Gu Nianyi, "I saw your grandson looking crooked when I was walking, and I stabbed you with evil thoughts. What is my motive?"

"The motive is me pulling." Gu Nianyi pointed at him, "You said it yourself."

"Damn, you're really cool." Xiao Wang scolded.

Xiao Wang had an idea, and pointed to the surveillance screen: "Is there a nurse at Professor Lu's house, a babysitter or something? Is he also in this hospital? In order to fight for inheritance or something... There have been several cases like this in recent years."

"I checked." Gu Nianyi arched his back and looked at the monitor listlessly, "I checked early in the morning, and there is no close nannies or nurses around the professor, let alone a will."

"That daughter is the sole heir..." Xiao Wang also supported his head with his hands, "According to what you said, his daughter is very suspicious, and... how do you explain that high-end locator and that strange note?" ? Don’t tell me there are Crouching Tiger, Hidden Dragon FBI agents in a private hospital.”

"..." Gu Nianyi waved his hand, just when the phone rang, the other party said, "Gu police, you still come to the hospital today, we have checked the garden area, but we still haven't found anything."

"Thank you." Gu Nianyi said, "Have they checked the staff dormitory carefully? Go there again, maybe there are important clues. Ah yes..."

Gu Nianyi thought about it: "Check all the toilets and canteens for me."

"I've checked it several times before." The other party said, "The toilet's sewer entrance, as well as the water tank, knives, chopping boards, and corners have all been checked. If necessary, we are going to start dismantling the toilet."

"Check again." Gu Nianyi said, "Thank you for your hard work... I will check again today."

"Okay, no problem." The other party said, "See you there."

Gu Nianyi hung up the phone and relaxed his shoulders.

Gu Nianyi went back to his place, glanced at his watch, and then looked at the monitor, unknowingly, for almost an hour and a half.Before he was ready to sit down, Gu Xinxin ran over and said, "Gu Nianyi!!! Gu Nianyi come here quickly!"

Last night, several police officers from the group that went to arrest Gu Nianyi gathered together. Gu Nianyi stood behind them like a beacon, and said, "What are you looking at?"

"Gu Zai! You're here." Little Sun Chengming, who went to Wei Ming's house with him last night, saw Gu Nianyi coming, and quickly made room for him, "Come on."
