Chapter 2 Covering up the evidence of murder

After a brief observation, Akikawa Sosuke became increasingly aware that the current situation was not favorable to him.

"The blood that stained the clothes was still bright red, which means that the oxygen content in the blood was still high..."

“The reaction of life can also be seen very clearly around the wound.”

"He really died from a knife wound."

The blood is bright red, which means that it has not been exposed to the air for too long.

The living reaction near the wound also proved that the woman was still alive when she was attacked by the dagger.

Plus the car was locked and the windows were closed.

This undoubtedly raises the suspicion that the original owner is the murderer.

"If the blood starts to turn black, or if the body shows signs of rigor mortis, there is still room for maneuver. But now this woman has obviously just died, and it is impossible to reduce my suspicion..."

When the blood starts to turn black and the body shows signs of rigor mortis, it is clear that the person has been dead for a long enough time.

As long as the time of death of the deceased can be prolonged, or the time for the police to discover the body can be delayed, there are still many possibilities for manipulation.

However, now that the police sirens had been heard, it was a foregone conclusion that he would be regarded as the prime suspect.

"Since I'm already suspected of being the murderer, what I need to do now is not to eliminate my suspicion as the murderer, but to make sure that the evidence left at the crime scene is not enough to directly prove that I am the murderer."

Akikawa Sosuke looked at the clothes on the woman's abdomen. The part that was not soaked with blood was left with obvious marks because he had just pushed the woman away with his bloody hands.

He stretched out his right hand and gently rubbed the clothes of the woman next to him with the knuckles of his middle and index fingers.

"Cotton clothes, so my fingerprints can be covered with blood."

Fingerprint detection mainly detects the oil and sweat on the fingers, but blood can roughly cover the oil and sweat left on the clothes.

Coverage varies depending on the material of the garment.

Once absorbent cotton clothing like the one women wear is stained with blood, the original oil and sweat will be difficult to detect.

Akikawa Sosuke carefully grabbed the clothes with his fingerprints on them, pulled them to the wound and pressed down.

Suddenly, blood gushed out from the wound, and that part of the clothes also turned bright red.

In this way, everything, including Akikawa Sosuke's bloody palm print, was covered with blood.

Akikawa Sosuke repeated it twice, and after soaking the woman's clothes with his bloody fingerprints, he looked at the dagger inserted in the woman's abdomen.

"When I woke up just now, I was holding this dagger tightly in my hands. Now I can basically conclude that this is the murder weapon that caused the woman's death. But in this situation, there is no condition to get rid of the murder weapon at all."

Regardless of whether the original owner killed this woman, his situation would take a turn for the worse if the police saw the dagger that he had touched with his own hands.

Unfortunately, there is no way to get rid of the murder weapon now.

"If I can't hide the murder weapon, then I can only cover up the traces of me touching it."

Akikawa Sosuke once again grabbed the hem of the woman's clothes stained with blood on her abdomen, and carefully wiped the handle of the dagger with the blood-soaked clothes.

As for why the parts not soaked with blood were not selected, it was mainly because under the simple conditions, it was impossible to completely remove the blood.

Many inexperienced murderers think they can cover up the crime by simply wiping away the blood.

They don't know.
Even if you wipe the blood completely with a cloth or paper towel, there will still be traces of "being wiped".

As long as the police detect bloodstains through the luminol reaction, any attempt to cover up the bloodstains will be exposed instantly.

After wiping the handle of the knife completely with the blood on the clothes, Akikawa Sosuke once again carefully used the blood from the woman's abdomen to soak the clothes he had just touched.

Of course, it was not enough to simply erase the traces of touching the dagger handle. After all, any detective with a brain would have guessed that he was trying to cover up his fingerprints with blood after seeing the blood on the dagger handle.

"You must completely sever my connection with this dagger."

Akikawa Sosuke carefully lifted the woman's shirt and observed the wounds on her abdomen and chest.

Just as Akikawa Sosuke expected.

He found that most of the wounds were not perpendicular to the woman's body, but were tilted towards the passenger seat where he was.

"I'm right-handed."

The driver's seat of the car was on the right side, and the wound was tilted towards him, which just fits the logic of a person with a dominant hand on the right facing the woman.

Even for experienced agents or killers, it is difficult to cover up their dominant hand in an emergency.

Not to mention the situation where a woman is sitting in a car seat.

In this situation, it is several times more difficult to get the knife to enter a woman's body vertically than when she is lying flat on the ground.

After identifying the dominant hand of the murderer who killed the woman, the next thing to do is clear -

Akikawa Sosuke pressed his right hand hard on the storage box opposite the seat, then raised his foot and stomped hard on his right hand.

Accompanied by a crisp "click" sound, piercing pain rushed straight to the brain.

Akikawa Sosuke tried hard not to make any sound.

Because before he completes the final finishing work, he must not attract anyone.

If anyone finds out that their car is locked, all their efforts will be wasted.

Akikawa Sosuke had no time to care about his right hand that was bent in an impossible arc. He forced himself to lean forward and pressed the unlock button on the main driver's seat with his knuckles.

After hearing the sound of the car door lock popping open, Akikawa Sosuke suddenly relaxed.

"Although there are many ways to lock the car after the murderer left, with me as the prime suspect, the police simply cannot consider that direction."

"Once it is determined that the car has always been in a 'secret room', there will be no way to defend it."

After relaxing and slumping back in the seat, feelings of fatigue and dizziness suddenly hit Akikawa Sosuke's mind.

It was not until this time that Akikawa Sosuke discovered it.

Even though his spirit was already exhausted to the extreme, his breathing frequency and heart rate were still so fast that it frightened him.

The sound of the violent heartbeat was extremely piercing.

Amid the thumping sound of the heartbeat, Akikawa Sosuke also caught the humming sound of the engine.

"I thought it was just dizziness caused by excessive blood loss, but it turned out to be carbon monoxide poisoning."

Akikawa Sosuke was only concerned with dealing with the traces of the original owner's crime, but completely ignored another major threat that frequently occurred at the scene of the car accident -

Carbon monoxide poisoning caused by incomplete combustion of gasoline due to engine damage.

But when he noticed this, he had completely lost the ability to continue moving his body.

However, this situation did not make Akikawa Sosuke feel panic at all.

Before his consciousness fell into darkness, Akikawa Sosuke's lips moved slightly, and he uttered words in a voice as soft as a mosquito:
"God help me too."
