National Forensic Doctor

"Let me sum it up, not a serial killer?"

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

He was a little unsure now whether to be happy or annoyed. Of course you should be happy when there is a big breakthrough in the case, but not the serial killer - when the case has no clue, of course you should be worried about the serial murder, but when there is a breakthrough in the case, shouldn't you be upset about the case? Isn't it a serial murder case?

As the deputy director in charge of criminal investigation in one of the poorest counties in Qinghe City, Director Bai Jianbai not only hopes that the case can be solved, but also hopes that the money can be used wisely, and preferably there will be some breakthroughs and opportunities to double...

Jiang Yuan interrupted Bai Jian's fantasy with one sentence: "It's not a serial killer. Now we should go back to the original idea. The murderer is most likely an acquaintance, and he is probably a villager in this village. The footprints left in the small shop are closely related to the current situation in the village. The people who stay do not match the situation, and given the position abandoned by the door stick, people who live and work outside the village should be considered.”

"Someone came and came back?" Bai Jian suddenly had an idea of ​​​​the work. This was originally the most normal investigation idea. Everyone was just scalped by the victim and felt numb.

Even if you are a criminal police officer, you may not encounter a serial killer once in your life, especially such a perverted one. Just like ordinary people who fall in love with new people every week, they never encounter the sweet love stories in movies. Everyone is acting, but if you act for real, you are too perverted.

In the entire participating group, there must be one person who can continue to take the lead.

Jiang Yuan was noncommittal about Bai Jian's investigative ideas, saying: "I don't think it should be too restrictive. If it can be confirmed that it is indeed the scalp of a dog, then the case will enter the second half. I think a lot of money can be invested in this case." A little, more investigation directions, try to be as comprehensive as possible.”

The biggest difference between real investigation and the stories in detective novels is that the investigation 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 Murder Case" pump out 38 trucks of fecal water and then use a sieve to filter human tissue in it? Because there is no evidence. Even if they know that the husband killed his wife, this case is still unfounded. Undetectable.

Jiang Yuan urged Bai Jian to be here too. Predicting a more likely investigation direction can certainly reduce costs and reduce burdens, but if you lose the opportunity, you may lose evidence.

In the end, if only one footprint is compared, the case will be too persuasive. The so-called evidence is difficult to establish in isolation, and footprints are a kind of indirect evidence. It can only prove that the murderer has been to a certain place, and even the specific time cannot be determined. Therefore, footprints alone cannot actually advance the proof of the case to the point where the murderer was in a certain place at a certain time and had a certain interaction with someone, and the murderer killed someone.

A very natural and reasonable doubt. Since the face of the deceased could be skinned by a dog, could the victim be killed by another person or another animal, and the suspect just appeared in the wrong place at the wrong time? Location, got into a fight with the victim at the wrong time?

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

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

"Well, this case is difficult. The fact that the dog bit the scalp is difficult to prove because the skin is torn off and there are no teeth marks left on the remaining muscles on the scalp. The current speculation has not been confirmed. We still have to face it with the greatest strength." Jiang Yuan showed off a little bit of emotional intelligence, and then said: "Now let's catch the dog."

"Understood. It has been arranged." Bai Jian paused and then said: "At the same time, based on the victim's relationship network, we will list the scope of the list as soon as possible for further screening."

"Well, the murderer should be a man between 35 and 40 years old. He is between 1.6 and 1.68 meters tall. He weighed between 140 and 160 pounds at the time of the crime. He is right-handed and has short and wide steps. Around 65, the footprints are mainly divided and followed." Jiang Yuan said, and then said: "I will ask Wang Chuanxing to send you a message later, and then write an identification report of the footprints."

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

Based on the conditions given by Jiang Yuan, even if the victim's relationship network is more complicated and the list is longer, the difficulty will become very small after a little screening.

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

There were 22 dogs in the village, and 20 were arrested. Two of them were lucky and happened to be playing outside the village, and people were sent to arrest them.

The police dog squadron, which contributed most to the dog-catching operation, became uneasy after arresting the suspect dog.

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

"The three dogs involved in the case are definitely dead." Jiang Yuan told the truth, and then added: "There are more than a dozen dogs left. As long as they are proven innocent, I will cook a meal for them and put them back."

"How do they prove their innocence?"

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

Li Li was a little hesitant: "Can you see a dog's feet? You can't be wrong."

"No." Jiang Yuan said and ordered: "This job will be left to you. You call Shen Yaowei to make rubbings of the dog's footprints. We will compare them later. In addition, they may also be used for follow-up. of evidence.”

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

"Suspect dog."

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

Jiang Yuan spread his hands: "You should ask the prosecutor to see if he agrees. If he agrees, I will not object...I won't do it anyway. Let Miao Ruixiang and Shen Yaowei handle this job."

The three dogs involved in the case will be executed and dissected even for reasons of evidence preservation. For forensic doctors, there is actually no psychological barrier to dissecting dogs. During their studies, forensic doctors, like medical students, learned practical techniques by dissecting dogs.

If you want to do scientific research, even if it is more common or simple, dogs will be used. In this matter, it’s not that monkeys are difficult to use, but dogs are more cost-effective.

In fact, a forensic doctor like Jiang Yuan who can identify suspect dogs is already a lucky dog ​​in Tangui Village. Otherwise, if the suspect dog cannot be identified clearly, every one of the 22 dogs in the village will have to be examined. Anatomy.

Li Li was the squadron leader of the police dog squadron and a senior criminal police officer. Seeing that the matter had come to an end, there was nothing to belabor about, so she turned around and made arrangements.

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

There are still 22 dogs participating in the banquet. Two escaped dogs have found their way back. In addition, there are three staffed police dogs sitting in the chief position. The number of dogs in Tamgui Village has not changed, just like that day.
