A perfect crime? To me, it's full of flaws!

In the conference room, Qi Feng and Gao Qiu exchanged a glance.

Neither of them spoke, but they both saw helplessness in each other's eyes.

How many questions did the killer leave behind at the scene last night?

many!

There were quite a few obvious flaws that the two of them could spot at a glance.

From the second wine glass that disappeared from the wine cabinet, to the wine bottle that was wiped so clean that not even the deceased's fingerprints remained, to the so-called suicide note printed on A4 paper even though the family didn't have a printer.

Each and every one of these incidents revealed a huge flaw left by the murderer.

But the question is, is this case easy to investigate?

It's really hard to find out.

The reason is simple: although the murderer was extremely crude in his logical disguise, he was quite thorough in cleaning up the physical traces.

Before leaving the scene, he either completely destroyed everything he touched, or simply took away any biological traces he might have left behind.

There were no unfamiliar fingerprints, no extra footprints, and not even a single hair or skin flake belonging to the killer.

The police could see through his clumsy attempt to fake a suicide and were 100% certain that it was a homicide, but they couldn't obtain any direct physical evidence pointing to the killer's specific identity.

Moreover, if this case had occurred in an ordinary residential area, the police would have had plenty of ways to solve the case given that all traces at the scene had been cleared.

According to standard criminal investigation procedures.

Investigators could easily identify suspects by conducting large-scale interviews and investigations of neighbors or by directly accessing nearby public surveillance cameras, screening frame by frame to identify people who entered and exited during the time of the incident.

But where is this?

This is the Zheng family!

The building where Zheng Furong lives is inhabited by people with the surname Zheng, both upstairs and downstairs.

Although Zheng Furong, who died in the bathtub last night, was also a member of the Zheng family by blood.

But now that the person is dead, it's absolutely impossible for the neighbors in this building to betray another living member of the Zheng family to the police for the sake of a dead person.

Early this morning, Gao Qiu's investigators had already knocked on every door in the entire building and visited each household. The statements they finally obtained all seemed to have been pre-arranged, with each person claiming to know nothing.

After all, everyone in this residential area is related by blood; their ancestors can be traced back several generations.

More realistically, Zheng Furong's family was not familiar with their neighbors in the building at all.

Zheng Furong's parents live and work away from home all year round and can't return to the Zheng family's old house even once a year.

As for Zheng Furong herself, she only came back to stay for a few days occasionally after she was transferred to work at a private hospital under the Zheng family in the last two years.

The distant relatives who rarely even greet you when they come and go are nothing compared to your own family members with whom you live every day.

Bound by both clan interests and personal relationships, all the Zheng family members in the building tacitly chose to remain silent when questioned by the police, refusing to utter a single word and thoroughly adhering to the principle of avoiding trouble.

The path to visit the neighbors was blocked the moment I entered the house.

As for surveillance, which is the most relied-upon method for investigating cases.

Then there's even less hope.

The police officer in charge of retrieving the surveillance footage reported back early in the morning that all the key surveillance cameras in Zheng Furong's building and the surrounding area were broken.

Moreover, after verification by the technical department's back-end maintenance records, it was confirmed that these surveillance cameras were not maliciously damaged by chance on the night of the incident.

The recording work had already stopped completely a week ago due to aging wiring, and the property management company had been dragging its feet on repairs.

The trail leads here, and the surveillance route has completely ended.

As for the two unfamiliar police officers who were specially transferred from the Municipal Bureau yesterday evening, they staked out downstairs all night but also found nothing unusual.

The two investigators cannot be blamed for dereliction of duty.

After all, this is an old-style residential building with a front door, back door, and connecting corridors that lead in all directions.

You really can't expect just two police officers to be able to keep a close watch on all the entrances and exits of the entire building.

All witnesses remained silent, physical evidence was completely cleared away, and surveillance footage became useless long ago.

But Qi Feng and Gao Qiu, sitting in the conference room, weren't in such a hurry at the moment.

Faced with what seemed like an unsolvable predicament, the two remained remarkably calm.

Because the two of them had simultaneously come up with an excellent breakthrough.

Those are Zheng Furong's parents!

Yesterday's background check clearly showed that although Zheng Furong's mother was a member of the Zheng family, she was a marginal figure within the family.

As for Zheng Furong's father, he was a son-in-law who married into the family from another family and suffered a lot of cold treatment. He had no feelings for the Zheng family from the bottom of his heart.

The elderly couple spent their entire lives working for ordinary companies, living on a fixed salary, and were almost completely cut off from the core circle of the Zheng family.

Now, their only daughter is dead.

He died in the Zheng family's house without any explanation.

Qi Feng and Gao Qiu firmly believe that they can overcome this pain of losing their daughter.

These parents would never swallow their anger and let their only daughter, whom they had raised with such care, die so mysteriously, just for the sake of the so-called reputation of the Zheng family clan.

Moreover, Qi Feng and Gao Qiu absolutely refused to believe that the daughter they had raised from childhood was real.

Such a big change in the last two years, the parents would be completely unaware!

Once we find these parents, we'll have clues and a breakthrough!

Once this point was understood, the direction of our next actions became completely clear.

After briefly explaining the tasks at hand to the task force and ensuring everything was ready, Qi Feng and Gao Qiu did not linger on Zheng's territory. They prepared to leave Zheng's place temporarily and head directly back to the city.

They wanted to meet Zheng Furong's parents formally in the city.

In any case, Zheng Furong's body needs to be sent back to the Municipal Public Security Bureau's Forensic Center immediately for further detailed autopsy, according to procedure. There is no point in leaving it with the Zheng family.

Rather than remaining constrained in this clan territory where eyes and ears are everywhere and every move is being watched, it's better to withdraw voluntarily.

Back to the city bureau, back to the police's home turf.

There, we must completely break free from the Zheng family's circle and find a way to break the deadlock from the outside!
