Diary of a Criminal Investigator

Chapter 210: Someone Else Involved


In early spring, the temperature is unpredictable.

The stairway where the crime took place is crowded with onlookers—some in short sleeves, some in sweaters, and others in shorts.

Each of them stretched their necks, wanting to see what's happening with Wang Hui, who was identifying the scene at the doorway.

It's as if everyone isn't recognizing a colleague of over ten years but rather a man-eating gorilla escaped from a zoo.

Suddenly, someone becomes an object of public spectacle.

But the glaring police cordon, with what seemed like barbed spikes, deterred anyone from getting too close—they all kept their distance.

Wang Hui stammered, facing Wang Yishan's questions, he hesitated, then pointed to the sofa in the living room.

"It was... it was from the sofa. She was standing by the coffee table, I was on the sofa, she threw something, and I went to the kitchen from the sofa."

"The first strike... was by the coffee table. She stood there, thinking I wouldn't dare hit her, so I struck the first blow."

"And then, where did the victim run after being attacked?"

"The bedroom. She went into the bedroom, and that's where I killed her."

"The bedroom? Wang Hui!"

Wang Yishan pointed to the bloodstains on the edge of the entrance and the wall: "Then what's with the bloodstains here?"

"This..." Wang Hui looked at the bloodstains and hesitated slightly: "Oh, I remembered wrong, she first ran from the coffee table to the door, trying to escape."

"I struck her again at the door, then dragged her back, and she ran towards the bedroom."

"When she tried to escape at the door, where did you strike her?"

"The back, I think, can't remember exactly."

The back?

Wang Yishan's expression shifted; he'd seen the victim's body.

There were no wounds on the back at all!

Of course, from Wang Hui's account, analyzing it, the victim fled from the coffee table in the living room towards the entrance, and Wang Hui pursued from behind and should've injured the victim's back.

However, in reality, the victim had no knife wounds on the back.

The autopsy result was already out, the fatal wound was a knife wound that almost severed the neck.

In addition, the victim had knife wounds on the front chest, both arms, abdomen, and face, but none on the back.

This indicates that during the entire murder process, the victim was always facing the perpetrator, using her arms to block the assailant's strikes.

On the other hand, Wang Hui said the victim was dragged into the bedroom at the entrance door.

But there were no drag marks on the floor at all.

Traces of blood dragging are very easy to judge, even non-professional people can see it at a glance.

For professionals, they can deduce the dragged body's weight, height, and injury severity from the blood's drag area, width, and edge burrs.

Wang Hui was taken away.

He didn't tell the truth at all, the murder process he identified was completely different from the process analyzed from the bloodstains at the scene.

"Old Liu, I'll leave the scene here to you, I'll go back and personally interrogate Wang Hui."

Liu Guodong nodded, Wang Hui was lying at this point, which means there's only one possibility.

He didn't commit the murder, he's covering for someone else.

With this direction, breaking through the confession shouldn't be difficult.

However, contrary to everyone's expectations, Wang Hui was extremely uncooperative in subsequent interrogations.

He firmly insisted that he was the murderer, as for the murder process, Wang Hui claimed he was too nervous at the time to remember.

Water District Criminal Investigation Team meeting room.

"Wang Hui is obviously lying!"

The group was discussing how to get Wang Hui to tell the truth.

From the current situation analysis, it was confirmed that Wang Hui wasn't telling the truth.

Not telling the truth implies the murderer is another person.

And the longer Wang Hui delays, the greater the possibility for the real murderer to escape.

"In that case, we can't stop interrogating Wang Hui, but we also can't just rely on interrogating Wang Hui, hoping he'll tell the truth."

Wang Yishan's experience was still seasoned, he quickly formulated a response plan.

"With Liu Guodong in charge of following up at the crime scene, any discoveries there will be reported immediately."

"On the other hand, conduct a comprehensive review of yesterday's surveillance footage of the housing complex."

"Wang Hui covering for someone suggests a very close relationship with the murderer."

"Focus on checking all the people associated with Wang Hui who entered and left the complex yesterday!"

Several action teams began their work quickly.

One team combed through Wang Hui's relationships, while another focused on reviewing surveillance footage.

The East Garden District was a unit-funded housing built many years ago, with relatively old facilities. Fortunately, with regular maintenance by the unit, the district's main gate and back door are equipped with cameras.

But the district has no wall, and the so-called gate doesn't serve much purpose.

Whether the surveillance footage can capture valuable clues is highly uncertain.

A third group re-examined and revisited the residents of the building where the crime occurred.

"They fight every few days, poor Wang Hui, how beaten he is by his wife."

"I think Wang Hui was truly provoked; considering his wife's demeanor, it's not easy for him to have endured until now."

"They don't have children, I've heard it's because Wang Hui can't have any, but who knows."

"This house originally belonged to Wang Hui's parents. They couldn't get along with the daughter-in-law, got driven out years ago, and now the elderly couple rents a place outside."

The neighboring residents' evaluations of Wang Hui's family clearly leaned in his favor.

As for who else visited Wang Hui's house last night, there was no definite account.

"People come and go in the building, can't remember."

"When the fight started at Wang Hui's place last night, it was almost midnight, we didn't pay much attention. They fight all the time…"

Crime scene.

Lu Chuan was collecting the drip-shaped bloodstains at the entrance door.

When Wang Hui identified the scene earlier, Lu Chuan specifically observed Wang Hui's hands.

There were no signs of injury.

That doesn't make much sense.

Analyzing the scene, the victim fiercely resisted when attacked.

The spatter bloodstains were elongated and scattered over a considerable distance, indicating the perpetrator used significant force.

Murder, while seemingly easy, isn't all that simple.

For example, at the scene of Wang Hui's wife's murder, the perpetrator struck multiple times, from the living room to the bedroom, killing only through continuous assault.

During this, the victim put up intense resistance, making it highly likely for the assailant to have been injured.

Particularly in the hands, where strong blows increased the likelihood of injuries, at least minor abrasions.

But Wang Hui didn't have any injuries on his hands.

This was a point of suspicion.

Furthermore, Lu Chuan found another drop-shaped bloodstain next to the spattered one at the entrance door.

Such a bloodstain requires the source to have been relatively still for it to form.

Given the victim's frenzied efforts to escape at the time, it's unlikely she would have left such a bloodstain pattern.

Thus, this drop-shaped bloodstain is likely left by the murderer.

From the approximate height of the drop, it was likely from hand-level, but Wang Hui's hands weren't injured.

So, who left this drop-shaped bloodstain?
