Chapter 877 Suspect Dog

"Let me summarize, it's not a serial killer?"

Director Bai Jianbai patted his stomach with his hand, making a popping sound.

He was a little unsure whether to be happy or upset. He should be happy about the breakthrough in the case, but it's not a serial killer - when the case is unclear, of course you should worry about the serial homicide, but when the case has a breakthrough, should you be upset that the case is not a serial homicide?

As the deputy director of criminal investigation in the poorest county of Qinghe City, Director Bai Jian not only hopes that the case can be solved, but also hopes that the money can be spent on the right things, and it would be best if there is a chance of explosion and doubling...

Jiang Yuan interrupted Bai Jian's fantasy with one sentence: "It's not a serial killer. Now we should return to the original idea. The murderer is most likely an acquaintance, and it is very likely a villager in this village. The footprints left in the store do not match the people who are currently staying in the village. In addition, the location where the door-topping stick was abandoned should be considered as people living and working outside the village."

"Someone came and went?" Bai Jian immediately had a work idea. This was originally the most normal way of investigating. Everyone was just numbed by the victim's scalp.

Even if you are a criminal police, you may not encounter a serial killer once in your life, especially this kind of perverted one, just like ordinary people fall in love every week, changing new people every week, but you can't encounter the sweet love story in the movie. Others are acting, if you play it for real, you are too perverted.

There has to be someone in the entire group who keeps going.

Jiang Yuan was noncommittal about Bai Jian's investigative ideas, saying, "I don't think we need to be too limited. If we can be sure that it was indeed a dog scalp, then the case will enter the second half. For this case, I think we can invest more, have more investigative directions, and try to be more comprehensive."

The biggest difference between real investigation and the stories in detective novels is that the investigative behavior has costs, and at the same time, the results of the investigation must be presented in the form of evidence.

Why did the police in the "Hangzhou Wife Killing Case" draw 38 trucks of fecal water and then use a sieve to filter human tissue in it? Because there was no evidence, even if they knew that the husband killed his wife, the case would still be rootless and could not be solved.

Jiang Yuan urged Bai Jian to be here. Guessing a more probable investigative direction can certainly reduce costs and reduce burdens, but losing the initiative will likely result in losing evidence.

In the end, if only one footprint is matched, the persuasiveness of the case will be too poor. It is said that a single piece of evidence is hard to prove. Footprints are even more of an indirect evidence. They can only prove that the murderer has been to a certain place, and even the specific time cannot be determined. Therefore, with only footprints, it is actually impossible to advance the proof of the case to the extent that the murderer was in a certain place at a certain time, had a certain interaction with someone, and the murderer killed someone.

A very natural and reasonable suspicion, since the face of the deceased can be peeled by a dog, then the victim can be killed by another person or another animal, and the suspect just appeared in the wrong place at the wrong time and had a fight with the victim at the wrong time?

Jiang Yuan naturally does not allow such a situation to appear in his case, so he specifically explains it.

Bai Jian also immediately realized Jiang Yuan's needs and quickly responded, saying: "The investigation of the suspect should be wider."

"Well, this case is difficult. The dog bit the scalp, because the skin was torn off, and there were no teeth marks on the remaining muscles on the scalp, so it is difficult to prove. The current speculation has not been confirmed, and we still have to face it with the greatest strength." Jiang Yuan raised his emotional intelligence a little bit and said: "Let's catch the dog first."

"Understood. It's already been arranged." Bai Jian paused, and then "At the same time, we will list the range of the names as soon as possible according to the victim's network of relationships for further screening."

"Well, the murderer should be a male between 35 and 40 years old, between 1.6 and 1.68 meters tall, weighing between 140 and 160 kilograms at the time of the crime, right-handed, short steps, step width of about 65, and footprints are mainly split steps." Jiang Yuan said, and then said: "I will ask Wang Chuanxing to send you a message later, and then write a footprint identification report."

"Okay, that's good." Bai Jian's confidence has increased greatly.

According to the conditions given by Jiang Yuan, even if the victim's network of relationships is more complicated and the list is longer, it will be very easy to screen it a little.

Soon, the dog catching team also sent back the news.

There were 22 dogs in the village, 20 were arrested, and two were lucky enough to be playing outside the village, and people have been sent to arrest them.

The police dog squadron, which contributed the most in the dog catching operation, became uneasy after arresting the suspected dogs.

Li Li came to Jiang Yuan on purpose and asked, "What should we do with these dogs?"

"The three dogs involved in the case are definitely finished." Jiang Yuan told the truth, and then said, "As for the remaining dozen dogs, as long as they are proven innocent, I will cook them a meal and let them go."

"How can they prove their innocence?"

"Look at their feet." Jiang Yuan looked at Li Li calmly.

Li Li hesitated a little: "Can you see the dog's feet? I'm not wrong."

"No." Jiang Yuan said and ordered: "This job is left to you. You call Shen Yaowei to take rubbings of these dogs' footprints and compare them later. In addition, they may be used as evidence later."

Li Li agreed and asked again: "That...innocent dog..."

"Suspected dog."

"Okay, the suspect dog... can the suspect dog just have an operation?" Li Li knew it was unreliable, but she still had some hope.

Jiang Yuan spread his hands: "You ask the prosecutor, if he agrees, I have no objection... Anyway, I won't do it, this job will be left to Miao Ruixiang and Shen Yaowei."

The three dogs involved in the case will be killed and dissected, even for the reason of evidence preservation. For forensic doctors, dissecting dogs is actually not a psychological barrier. During school, forensic doctors, like medical students, learn practical techniques by dissecting dogs.

If you want to do scientific research, ordinary and simple ones are also done with dogs. In this matter, it's not that monkeys are not easy to use, but that dogs are more cost-effective.

In fact, Jiang Yuan, a forensic doctor who can distinguish suspect dogs, is already a dog fortune in Tangui Village. Otherwise, if the suspect dogs cannot be distinguished, all 22 dogs in the village will be dissected.

Li Li is the captain of the police dog squadron and a senior criminal police officer. Seeing that things have come to this point, there is nothing to say, so she turned around and made arrangements.

Jiang Yuan turned around and found the village chief's house. After paying some money, he used the LV5 dog meal skill in the village chief's kitchen to prepare a big feast for all the dogs in the village.

There are still 22 dogs participating in the feast. The two escaped dogs have returned to the right path. In addition, there are three regular police dogs sitting in the chief position. The number of dogs in Tangui Village has not changed, just like that day of that year.
