I'm not a genius detective

Chapter 107 Both siblings have alibis

Branch interrogation room.

Wang Mengjie was handcuffed to a chair, head down, his hands trembling slightly.

After all, he was just a young man of twenty years old. He was arrested by the police and taken to the branch office. He must have been scared, and it's unknown whether he regretted it.

Throughout the entire ordeal, Wang Mengjie didn't utter a single word except when he saw the police and tried to run away. This basically indicates that he had resigned himself to his fate, making him easier to interrogate.

Indeed, when Fang Zhou mentioned his whereabouts in the early hours of the morning and Xiao Yuxuan, Wang Mengjie confessed to stabbing her.

He had been stalking Xiao Yuxuan for several days, and found an opportunity in the early hours of this morning. Without hesitation, he went up and stabbed her three times.

He had no intention of killing her; he stabbed her and ran away. It was all to avenge his sister.

"Do you know how dangerous and heinous your actions are?!" Fang Zhou slammed his fist on the table, angrily reprimanding her. "Three stabs! If even one of those stabs had hit her heart, or if Xiao Yuxuan had gone into shock from excessive blood loss before calling the police, you would be committing intentional homicide! Don't you understand the seriousness of the matter?!"

He was stabbed three times at random; it was indeed very dangerous.

It's lucky that Xiao Yuxuan didn't die, and it's also lucky for Wang Mengjie. According to the forensic report, Wang Mengjie shouldn't live more than ten years; he should be released before he turns thirty.

Inflicting serious injury intentionally, even with the victim's forgiveness, still warrants imprisonment, which is significantly different from causing minor injury.

Wang Mengjie, in a fit of emotion, shouted: "She's my sister! I have to stand up for her! She deserves it! That woman deserves it!"

At twenty, you're at an age where you're fearless and don't care about anything when your temper flares up.

Fang Zhou: "Have you thought about the price of standing up for yourself? How many years will you spend in prison! What will happen to your sister? What will happen to your parents? How much money will your whole family have to pay in compensation? Haven't you thought about any of that?!"

Xiao Yuxuan is still lying in the intensive care unit, and the medical expenses are a big problem.

The Wang siblings are both migrant workers, and their parents don't seem wealthy. For an ordinary family, this is a devastating blow.

Wang Mengjie was speechless: "I..."

A moment of impulsiveness has led to irreversible consequences, and one can only bear the price.

Dai Bin's parents arrived, and they were emotionally distraught, desperately wanting to see their son. The police officers from the Criminal Investigation Brigade were trying to calm them down and would later ask them about Dai Bin.

Xiao Yuxuan was stabbed by Wang Mengjie, but Dai Bin's death had nothing to do with Wang Mengjie. After stabbing Xiao Yuxuan, he went directly to the construction site and stayed with his friends all day without leaving. There are many witnesses, and his alibi is very strong.

Fangzhou and his team will follow up on this matter further.

At this point, it can be confirmed that this couple is involved in two separate cases. Regardless of whether the cases are related, there is at least more than one suspect.

Room inquiry.

Upon learning that her younger brother had indeed stabbed Xiao Yuxuan, Wang Mengqi completely lost any hope of survival, and her eyes quickly reddened.

Overwhelmed by guilt, she covered her mouth with her hands and trembled violently, accompanied by a profound sense of helplessness.

"I...I just fell in love with someone..."

Overwhelmed with emotion, Wang Mengqi broke down in tears.

She had a secret affair with Daibin, and then Daibin died.

Xiao Yuxuan confronted her and accused her of being a mistress, after which her younger brother stabbed Xiao Yuxuan and was arrested.

Dai Bin's death may not have been caused by her, but her brother's crime was entirely her fault.

In a way, she ruined Wang Mengjie's life.

Regardless of whether the feelings were pure or not, Dai Bin's extramarital affair is a fact, and Wang Mengqi's status as a mistress is also a fact, which is morally wrong.

The electronic evidence room has checked Xiao Yuxuan's phone and found no signs of misconduct. Based on the current investigation results, Xiao Yuxuan has not wronged Dai Bin.

Early this morning, Xiao Yuxuan went to a disco and an internet cafe. The surveillance footage showed that she was alone the whole time, without any strange men accompanying her, which also supports this point.

Willful, playful, and extravagant, Xiao Yuxuan is unable to provide Dai Bin with the emotional value he desires. These are her shortcomings as a wife, but she has not crossed any lines.

Dai Bin and Wang Mengqi were the ones who crossed the line.

If we really have to judge who is right and who is wrong, it seems that the Wang siblings are more at fault.

The technical squadron's footprint comparison results came back: one of the two new footprints found in Dai Bin's rented house belonged to Wang Mengqi.

The identity of the other footprint is unknown and does not belong to Wang Mengjie.

The technical squadron has a relatively mature theoretical system for judging human characteristics based on footprints. The gender is male, and the height is about 1.78 meters, with an error margin of 3 centimeters.

Due to the influence of the ground material, the weight cannot be determined.

The owner of the footprints is a prime suspect.

There was a cup on the coffee table at the crime scene, containing unfinished water. The forensic doctor has tested the water and confirmed the presence of poison.

From this perspective, Dai Bin's death resembled suicide, but the unfamiliar footprints remained unexplained.

"Besides you, does anyone else usually go to the house that Dai Bin rents?" Ji Bowei continued to ask Wang Mengqi.

Strictly speaking, if Dai Bin's death was a homicide, Wang Mengqi is the prime suspect because she had the perfect opportunity to commit the crime.

Given their relationship, Wang Mengqi could easily poison Dai Bin's water without arousing any suspicion, and would not need to provide an alibi.

Poisoning to kill also fits the characteristics of a female perpetrator.

According to big data, poisoning is often the primary method used in cases where women kill men, or at least as a preliminary measure. After all, men are naturally stronger than women, making it very difficult for them to succeed in a direct confrontation, and they are more likely to be countered.

Faced with Ji Bowei's question, Wang Mengqi, still reeling from the blow, stared blankly and shook her head, saying, "No, only I know he's in seclusion there creating." Ji Bowei: "Are you sure?"

Wang Mengqi: "It's true, he told me that he didn't tell anyone else except me, including Xiao Yuxuan."

Ji Bowei: "Why did he suddenly want to rent out a house?"

Wang Mengqi: "It wasn't sudden. He was stuck at home every day and lacked inspiration. He would go out to find a quiet place to write the beginning and end of his novels, and he didn't want to continue facing Xiao Yuxuan."

The inquiry process lasted a long time.

Wang Mengqi is the key. Recently, she has been in the closest contact with Dai Bin, and she is also the last known person to have met with Dai Bin. She needs to be closely monitored.

When asked about Dai Bin's enemies, Wang Mengqi said that there were many people who disliked Dai Bin, but she couldn't think of anyone who would kill him.

The friends who lent him money were at most in debt to a few tens of thousands of yuan. It doesn't make logical sense for someone to kill Dai Bin over a debt of a few tens of thousands of yuan.

However, the investigation should still be conducted. There is no shortage of mentally ill people in the world, and they may have multiple motives.

The problem now is that no one knows that Dai Bin rented a house in the suburbs. If Dai Bin died from homicide, even his wife Xiao Yuxuan doesn't know the exact location. How did the murderer find it?

Unless it's a long-term, secret surveillance, or... provided by Wang Mengqi behind the scenes.

Meanwhile, questioning of Daibin's parents has also begun.

The couple was unable to accept their son's sudden death, and their grief made the questioning more difficult, but it was still manageable.

According to Dai Bin's parents, they disagreed with Dai Bin's decision to marry Xiao Yuxuan. They felt they had a good eye for people and that Xiao Yuxuan was clearly not someone who could manage a household.

She dresses extravagantly, wears over-the-top makeup, and doesn't have a job. Besides being pretty and having a good figure, what else does she have?
As parents, they only hope that their son can find a reliable person to avoid uncontrollable problems after marriage.

Things are different now than they were in the past. Putting aside fate and free love, nowadays, men with a little money will generally choose beautiful partners, while beautiful girls will prioritize wealthy partners.

Being beautiful is a requirement, being rich is also a requirement, that's normal.

"He spends all his time hanging out outside, and when he gets home he just plays computer games and binge-watches TV shows. Is this how you live a life? It's like he married a tyrant!"

From their conversation, it was clear that Dai Bin's parents disliked Xiao Yuxuan very much, and their relationship with her was so bad that they often argued. This was why the two of them did not visit her in the hospital.

To be honest, that's a bit much.

No matter how bad the relationship is, if someone is in the intensive care unit, you still have to show your face, even if it's just for show.

At this moment, Xiao Yuxuan's parents have probably cursed the Dai family's ancestors for eighteen generations, and it will be difficult for the two sides to continue to have contact in the future.

There was no need for them to have any further contact. Dai Bin was dead, and the two had no children, so their marital relationship was completely over.

At most, they will negotiate and discuss the distribution of the estate in the future.

Since there are other first-order heirs, Xiao Yuxuan cannot inherit all of Dai Bin's property; she needs to set aside a portion of it.

Dai Bin's parents knew very little about their son, and after asking around for a long time, they couldn't get any useful clues. The investigators had to temporarily stop because they were trying to calm the elderly couple down.

Wang Mengqi's side.

Ji Bowei took out photos from the scene and showed Wang Mengqi the cup Dai Bin had drunk from, asking, "Does this look familiar?"

Wang Mengqi looked up and replied, "It looks familiar. I bought him the complete set of cups."

Ji Bowei: "How many cups are there in total?"

After discussing it with Hu Lihui and Fang Zhou, they changed their perspective and first checked whether any cups were missing.

Scenario: Suppose that Dai Bin died from homicide. Suppose that there was a second person present when Dai Bin was drinking water. Did the second person drink water?

If you drink from it, what happens to the cup?

Is it possible that they took it with them?

A cup used for drinking water will retain fingerprints and DNA, and a murderer with a certain level of counter-surveillance ability will not overlook this.

“Four cups,” Wang Mengqi replied.

Four?

Ji Bowei put down the photo in his hand.

According to the on-site investigation, there were three identical cups in total, and no fourth one was found.

This means that someone took the fourth cup.

At this moment, a police officer knocked on the door and came in. He bent down and whispered to Ji Bowei, "The time of death is accurate: 2 PM, within an hour's margin of error."

Having learned the key information from the autopsy, Ji Bowen looked at Wang Mengqi: "Were you in the coffee shop from noon to 4 pm today?"

He extended the time by an hour.

Wang Mengqi nodded gently: "Yes, I've been in the coffee shop the whole time."

There's no way to lie about this. There are other colleagues in the coffee shop with CCTV footage, and a simple check would confirm it.

The girl did not have the opportunity to commit the crime.

While murder can be ruled out, the possibility of knowledge of the crime or even complicity cannot be ruled out. The criminal investigation team cannot completely remove its focus from Wang Mengqi for the time being.
