Solving the case: Combining the police dog's olfactory genes at the beginning

Chapter 7 The smell of cigarettes, the nose makes another contribution

Luo Fei nodded and replied: "Master, how could I say such nonsense?"

Zhang Haiyang glanced at Luo Fei, then at the people on the balcony, and then said to Luo Fei: "Follow me."

Zhang Haiyang walked straight to the balcony.

"Team Zhao, we have carefully checked the entire room and found nothing. Apart from the traces of the deceased, there was no trace of the presence of the second person in the room." The cool female detective with a ponytail was reporting to Zhao Donglai, her delicate brows slightly raised. Frowning.

Hearing this, Zhao Donglai looked around and then said firmly: "If this case is really a homicide, there will definitely be traces left. As long as it is a crime, no matter how perfect the crime is, there will always be traces. Let's look for it again." .”

"Zhou Suo, Luo Fei has made an discovery." Zhang Haiyang's voice suddenly sounded at an inappropriate time, attracting the attention of several people.

Zhou Suo, Team Zhao and several members of the Criminal Police Team all stared at Zhang Haiyang and Luo Fei.

"Luo Fei, what have you discovered?" Zhou Weimin asked quickly when he heard that Luo Fei had discovered something.

I don't know if it was the confidence and confidence brought by the golden finger, but Luo Fei didn't feel nervous when he saw everyone staring at him.

"Zhou Suo, Captain Zhao, I smell a faint smell of cigarettes in the room, but the victim does not smell of cigarettes, so he probably doesn't smoke. I suspect that the smell is the smell left by the murderer smoking in the room." Luo Fei said calmly.

After Luo Fei finished speaking, several members of the criminal police team started discussing in low voices.

"I didn't smell it, did you smell it?"

"I didn't smell it either."

"Sister Yang Mei, do you smell it?" The girl with short hair and glasses also quietly asked the cool girl next to her.

The cold girl frowned and shook her head.

Then everyone looked at Luo Fei suspiciously. So many people didn't smell it, but Luo Fei was the only one who smelled it.

"Are you sure?" Zhao Donglai spoke at this time. Zhao Donglai didn't have much doubt. He felt that Luo Fei didn't need to lie. He was just a little surprised that Luo Fei had such a good nose. No one could smell it, but Luo Fei could smell it.

Seeing that everyone didn't believe it, Zhang Haiyang hurriedly said: "Captain Zhao, Luo Fei has a very good nose. You also know about the Gu Youguo case. It was Luo Fei who smelled the corpse odor that time, so we were able to find out Murder case, catch Gu Youguo.”

Luo Fei followed up with a firm reply: "I'm pretty sure there is a smell of cigarettes in the room."

"There is a smell of cigarettes in the room. It's possible that the victim smoked it himself. Just because the victim doesn't know how to smoke doesn't mean she can't smoke. What if she felt bad and smoked one." The crew-cut man from the criminal police team was suspicious. road.

Before Luo Fei could speak, the girl with a cool temperament refuted the crew cut man's words: "If the cigarette was smoked by the victim, then at least a lighter and the remaining cigarettes or cigarette butts should be found in the room."

Zhao Donglai looked at Luo Fei deeply, and then said: "If there is a smell of cigarettes in the room, it is very likely that it was left by the murderer."

"Now, based on the clues we have obtained so far, let's think about it. First of all: from the situation of the body falling from the scene, combined with what Comrade Luo Fei just said about the smell of cigarettes in the room, we will initially determine that this case is a murder." "Secondly, the deceased was thrown from the balcony by the murderer when he was unconscious or dead. Based on the height of the balcony, the weight of the deceased, the smell of cigarettes in the room, and the distance from where the body landed, one thing can be determined, that is, the murderer was A strong male with a height of at least 1.75 meters."

"Third point, the time of death of the deceased was around six o'clock in the morning, so that means the murderer left the crime scene after six o'clock, but when did the murderer enter the victim's room? How did he enter? And how did he leave? ? What is the relationship between him and the victim? It should also be noted that the murderer may be someone from the community or someone from outside. These are all things we need to find out."

"The last point, and the most important point, is the murderer's motive and why he wanted to kill the victim." At this point, Zhao Donglai looked at everyone inquiringly.

"There is no sign that anything in the room has been rummaged through. The victim's wallet, cash, and jewelry were not missing from the cabinet, so we can rule out the possibility of the murderer seeking money and murder." The crew-cut male detective immediately expressed his opinion idea.

"It's probably not a murder of love. The room is so tidy and there are no things for men. You can tell that the victim usually lives alone, so naturally there is no murder of love." The detective girl with glasses and short hair followed.

"It's probably not a vendetta."

Everyone expressed their opinions on the murderer's motive, and even debated when they encountered conflicting reasoning.

Luo Fei was also wondering about the murderer's motive at this time. As an author of suspense novels, he still had logical reasoning skills.

When everyone had finished talking, Zhao Donglai suddenly looked at Luo Fei and asked: "Luo Fei, what about you, what do you think the murderer's motive was?"

The last murder case in Gu Youguo and Luo Fei's smell of cigarette smoke just now made Zhao Donglai deeply impressed by Luo Fei, a young policeman, so he asked such a sudden question.

He wanted to see how Luo Fei was doing in other aspects besides his nose.

Luo Fei did not expect that Zhao Donglai would suddenly ask him, and was very surprised. As for Zhao Donglai's motive for the crime, he had been thinking about it just now, but honestly speaking, with the little information he currently had, he wanted to deduce the murderer's motive. Luo Fei I find it difficult, since Luo Fei couldn't figure it out himself.

"I don't know the murderer's motive, but I think the murderer and the victim should be familiar." Luo Fei replied.

"Tell me about it." Zhao Donglai asked curiously.

Well, Luo Fei nodded, and then said: "I took a look and found that if you want to enter the victim's room, you have to open the door and come in. And I also noticed that in this room, the door has a pin inserted inside. Once this kind of door is used, Put the pin on the inside, and no one can open it from the outside. Only the people inside can open the door, and the people outside can get in."

"The victim was killed around six in the morning, and at that time, the door should have been locked. If the murderer entered the room at that time and killed the victim, then as a stranger he would have no chance of entering, let alone kill."

"If the murderer entered the victim's room during the day, it means that the murderer had already planned the murder. If this was the case, he could not have waited until [-] a.m. to kill the victim and leave, because it was already dawn at [-] a.m. , many people have already gotten up to go to work, so it is easy to be exposed, and the murderer cannot be that stupid." Luo Fei analyzed.

"It makes sense. Indeed, the possibility of the murderer being a stranger is extremely low. It is probably an acquaintance who committed the crime." Zhou Weimin nodded in the affirmative after hearing this.

"Luo Fei is right. If the murderer is a stranger, it makes no sense logically, so I am more inclined to believe that an acquaintance committed the crime. And I would like to add that I think this case is not a premeditated murder. The murderer is Killing the victim at 6 o'clock in the morning, just like Luo Fei analyzed just now, it is already dawn at this time, not to mention office workers in the community, many old men and women have already gotten up to exercise. Committing a crime at this time is It is an extremely unreasonable choice, so the murderer should have chosen to commit the crime temporarily due to passion." Zhao Donglai said.
