After a surprise interrogation, Gong Yuanliang and Yan Sien confessed to the fact that they conspired to kill Bai Chuyue and blame Tang Chengji.

Now it seems that if it weren't for the second murderer entering the house to mend Bai Chuyue, then this case could be called an almost perfect crime.

Even if that knife didn't hit the vital point, it would still make Bai Chuyue die of excessive blood loss.

Of course, there is no perfect crime in this world, as long as it is done by people, it will definitely leave traces. Just like this case, during the fight, Bai Chuyue's nails still left Gong Yuanliang's dandruff tissue.

Harming others will eventually harm oneself, and what awaits Gong Yuanliang and Yan Sien will be punished by law.

However, what awaits our Serious Crime Team is still a homicide case with no clues.

According to the clues that have been available, we have sorted out the timeline of the case.

That night, at 8:30, it rained heavily in Gushui Town, and about ten minutes later, there was a large-scale power outage in Gushui Town.

At around 9 o'clock, Gong Yuanliang entered Bai Chuyue's home, killed people and set up the scene, but Bai Chuyue did not die immediately after being stabbed.

At around 10 o'clock, the time of Bai Chuyue's death was learned according to the autopsy, and then Tang Chengji received a text message and came to the scene of the crime, found Bai Chuyue's body and fled.

At 10:15, Bai Chuyun, the deceased's sister, arrived at the scene of the crime, found the body and called the police.

Therefore, the nearly hourly period from 9 o'clock to 10 o'clock that night was the process of Bai Chuyue's real killing.

And what happened in this hour is the crux of the case.

"If Jiang Tingbai's judgment is not wrong, then the murderer carried out the rape and murder after being drunk, and it is very likely that an acquaintance committed the crime."

In the office of the serious crime team, Li Meng suddenly spoke.

"It is very likely that an acquaintance will commit a crime, so we still have to look for clues from the social relations of the deceased." Jiang Tingbai slowly raised his head and said in a deep voice.

"Perhaps, this person is also one of Bai Chuyue's suitors." Xue Hang said lightly.

"The killer was a man, unemployed, between the ages of thirty-five and forty, divorced or widowed, and currently single. I have known Bai Chuyue for a long time, and it is very likely that she is a young person or a classmate, and she has kept in touch for a long time. The murderer must have pursued Bai Chuyue many times, but Bai Chuyue refused. On the night of the crime, he entered Bai Chuyue's home, saw the injured Bai Chuyue, and instead of sending her to the hospital, he raped and murdered, which showed that Bai Chuyue was bored with the murderer, which angered the murderer. ”

Li Mengmeng thought about it and gave a criminal profile of the murderer in this case.

"This criminal profile is very comprehensive, and I will use this as a clue to conduct a comprehensive investigation of Bai Chuyue's social relations." I nodded and said in a deep voice.

Immediately afterward, I pondered for a moment and said lightly: "Go back to the scene of the crime and take a look." ”

Our soldiers were divided into two routes, and the first team continued to investigate clues from the neighbors of Gushui Town, especially from Bai Chuyue's relationship between men and women. The other team returned to the scene of the crime and conducted a thorough on-site investigation at Bai Chuyue's residence. If the murderer and Bai Chuyue's lives have intersected for a long time, then there will definitely be some clues left in Bai Chuyue's life.

Picking up the long cordon, we once again came to Bai Chuyue's home. The place still retains its original appearance, with physical evidence signs on the ground and fixed lines drawn on the traces of the scene.

The blood had dried up, but a faint smell of blood could still be smelled.

Everything in front of us tells us that there was a homicide here the night before last.

Our mission this time is not to re-examine the traces of the crime scene, but to check Bai Chuyue's daily belongings and find some clues from them.

Bai Chuyue's house is not big, and there are no decent furniture and furnishings, the room is a little messy, and many of the supplies are relatively old, which shows that Bai Chuyue's life is not rich, and it is a little poor.

Her marriage is not happy, her husband is an alcoholic, drunk like life, drunk every day, and even domestic violence against Bai Chuyue and children. But Bai Chuyue still chose to endure it, and tried her best to maintain this not warm home.

Bai Chuyue has a habit of keeping accounts, and we found a thick ledger in a drawer, on which every important expense in life was recorded.

These expenses are nothing more than children's tuition fees, as well as the daily expenses of the family's daily necessities, and the amount is not very large. But as Li Meng flipped through it, the more he looked at it, the more he felt that something was wrong.

Because there are a large number of liquor purchase records in the ledger, and the number of purchases at each time is very huge.

Bai Chuyue's husband is an alcoholic, and it is relatively normal for the family to buy alcohol, but in the account book, the detailed amount of expenditure is not indicated.

"Buying alcohol is the biggest daily expense of Bai Chuyue's family, and her other expenses are recorded in detail, why isn't this the only one?" Li Meng muttered suspiciously.

I took the ledger and flipped through it quickly, focusing all on the monthly drinks expenses at home.

This kind of thing happened mainly two years before Bai Chuyue's husband died in a car accident, and there was no such situation in the past.

"It's definitely not because of carelessness, it's intentional." I slowly put down the ledger in my hand and said in a deep voice.

At this moment, Jiang Tingbai, who was conducting an investigation in another bedroom, made a major discovery.

"Lao Qin, Li Meng, come and see!" Jiang Tingbai suddenly shouted at us.

"What's wrong?" Li Meng and I left the house together and walked towards Jiang Tingbai.

In the other bedroom, Jiang Tingbai was standing on the edge of the bed, not moving.

Following his gaze, we found a large number of simple liquor under the bed, and all of them were in boxes. Although the packaging of the wine bottle is simple, the packaging of the wine box is very luxurious, and it is a gift box style at first glance, which is very suitable for visiting relatives and friends during the New Year's holidays.

I took out a bottle of liquor from the box, there was no logo on it, only a big brand name - rose wine.

It's a brand I've never heard of, and there's definitely no such brand of liquor on the market right now.

"Have you heard of this brand?" I handed the wine bottle to Jiang Tingbai and Li Meng.

"I haven't heard of it." Li Meng shook her head in a daze, she didn't drink, and she never understood the brand of alcohol.

However, Jiang Tingbai looked at the wine bottle in his hand carefully, and his expression was a little strange.

"I seem to have heard of this wine, which is a new brand that came out a few years ago, but it is not sold through a wide range of channels, and it is usually sold locally. But within a few years of its appearance, it suddenly disappeared, and since then there has been no such wine on the market again. Jiang Tingbai said in a deep voice.
