Chapter 23

Everyone has their own unique smell, which Xiang Kun felt more clearly after his sense of smell was greatly improved this time.

However, he had just woken up for a few hours this night, and he was still very unfamiliar with the distinction of various smells. Before at the crime scene, he had thought about whether he could find the smell of the perpetrator, and then track it down.

But Xiang Kun lacked a source of smell. The perpetrator should have left not long ago, and there was still a residual smell at the scene, but he couldn't distinguish it from the various smells, or there were too many options to be sure.

After the police arrived, there were more people at the scene, so it was naturally more difficult to track.

However, relying on his strong hearing, Xiang Kun heard the conversation between the police and knew that the murder weapon had not been found yet.

The murder weapon should have been stained with the victim's blood. Looking at the scene, there was no thing used to wipe the blood on the blade, so the blood on the murder weapon should still be left before it could be disposed of in time, or the wiped paper and cloth were still there. on the assailant.

Then Xiang Kun came up with an idea to see if he could find the perpetrator or the murder weapon by tracking the smell of blood.

The direction where the victim's blood smelled strongest was naturally the previous crime scene.

But Xiang Kun would not return there, but walked in another direction.

According to his judgment, when he saw the victim, the assailant would not leave for more than three minutes.

Before Xiang Kun smelled the smell of blood, he didn't see any suspicious people, nor did he hear any panicked footsteps. Obviously, the direction that the perpetrator fled after hurting someone was not his side.

After excluding one side, the assailant still has two roads to go, but one of the lanes leads directly to the main road outside, which is very lively. There are still many pedestrians during this time period, and there are also many surveillance cameras. is positioned.

Judging from the style of the assailant not attacking directly at the door of the ATM, but following to a relatively remote place before attacking, he probably wouldn't go there.

So Xiang Kun chose the remaining path and patrolled all the way.

But he basically couldn't follow the scent of the victim's blood, because if he did, he would definitely go in the direction of the crime scene.

Xiang Kun wasn't discouraged either. Anyway, he didn't take it as his task or responsibility to catch the perpetrator. He just tried to practice his olfactory tracking ability.

Xiang Kun imagined himself as the perpetrator, and every time he reached the intersection, he almost subconsciously chose to move on.

After walking so far, the smell of blood left at the crime scene was already very faint, and when Xiang Kun was about to give up on tracking, suddenly a faint, "familiar" smell was mixed with various thick and mixed smells In, smelled by him.

Xiang Kun immediately cheered up. The smell was the victim's blood smell. Although it was so faint that it almost dissipated, its source direction was different from that of the crime scene. That is to say, he could easily find the target.

Following the smell, Xiang Kun walked back and forth for more than ten minutes, and finally determined that the source of the blood smell was in an open trash can.

The garbage bin was obviously used for throwing household garbage for nearby residents. Some garbage bags containing kitchen waste were torn open, and there were soup, water, and food residues everywhere. Now that Xiang Kun's sense of smell has increased a lot, it is even more tormenting.

He had to maintain his concentration so that he could always lock on to the scent of the victim's blood.

Looking at the dustbin full of flies coiling around it, Xiang Kun couldn't help hesitating. He had no obligation to track down the suspect, so why go through the dustbin?

But after hesitating for a while, he still wanted to see if the target he was following was right, if it was something stained with the victim's blood, could it be the murder weapon?

Xiang Kun sighed, and leaned forward to drive away the flies on the dustbin.

Then began to lean over to rummage.

It didn't take long for Xiang Kun to find something stained with the victim's blood. It wasn't the murder weapon, but a pair of bloody cotton gauze gloves.

Xiang Kun didn't hold it directly with his own hands, but pulled a piece of clinker bag from the side, pinched the glove, took it up to his nose and smelled it, a smell mixed with various types made him beat three times in a row a sneeze.

However, he still keenly caught that trace of human smell from the stench.

It was the secretion of sweat glands, sebaceous glands and other skin glands on the hands. The smell was not so easy to dissipate in the gloves.

As for the smell of the victim's blood, needless to say, even without smelling, the blood stains on the gloves can be seen directly with the naked eye.

Xiang Kun hesitated for a while whether to tell Officer Chen where the gloves were, but after thinking about it, he threw the gloves back into the trash can and didn't call Officer Chen. It was really hard to find an excuse.

And he felt that with the strength of the police's search, they should be found here soon.

Of course, I hope that the trash can has not been cleared by the sanitation workers at that time.

Although he got the scent of the assailant, after Xiang Kun walked around the area a few times, he still found nothing. In the city, there are too many distractions, both sounds and smells.

The next day, Xiang Kun added his wechat with the number given by police officer Chen and asked about the progress of the case.

He didn't have much hope at first, because he knew that the police generally would not disclose the progress of the case under investigation, but to his surprise, Officer Chen sent him a photo directly.

The police's investigation efficiency was much faster than Xiang Kun imagined. In just one night, the identity of the suspect had been confirmed!

According to Officer Chen, the suspect had just been released from prison in March this year, and arrived in the city in April. Unexpectedly, he committed another major crime a few months later—the victim who was stabbed last night was rescued. Ineffective, has passed away in the early morning.

The suspect's photos and information have been sent to the station, the airport, various hotels and hostels, and the local TV station will release the wanted news later. It can be said that it is a matter of time before he is arrested.

Officer Chen also told Xiang Kun that if he saw the suspect, don't be impulsive, call the police, or call him directly.

In Xiang Kun's view, the suspect has basically already booked a prison meal. In this day and age, cameras are everywhere, real-name authentication is required everywhere, and ID cards are required to clear the way. Hunt him above.

In this case, Xiang Kun didn't even think about tracking down the suspect based on the scent he got. After all, this is a big city with a population of more than 10 million. Without a certain range, if he wanted to find someone by smell, he would have no choice. It is different from finding a needle in a haystack.

But what Xiang Kun didn't expect was that he would meet the suspect before he was caught.
