Diary of a Criminal Investigator

Chen Jiang switched the projector again, displaying a man’s watch.

"Vacheron Constantin?"

As soon as the watch appeared, Lu Chuan recognized it.

He also owns this watch.

Chen Jiang nodded with a smile, "This watch was given by Liang Juan to them within three days of their relationship."

"The watch brand, just like you said, Vacheron Constantin, priced at 200,000."

Damn!

A 200,000 watch?

Everyone was unsettled.

"Isn’t Liang Juan too generous?"

"Dating an old man and giving a 200,000 watch?"

"Really?"

Of course, it’s true.

This is the result of Chen Jiang’s investigation over the three days.

The 18 people Liang Juan dated, including the three who committed suicide like Wang Gang, all have such watches.

"Isn’t this a case of ’sacrifice a child, catch a wolf’?"

Although Liang Juan gave such expensive watches to everyone she dated, she received much more from them than the value of the watch.

"Is there any direct evidence of Liang Juan’s involvement in the charcoal suicide deaths of Wang Gang and the other two?"

To be honest, Lu Chuan is not concerned with how many people Liang Juan dated or how much money she took from them.

If Liang Juan dated these people for money or fraud, naturally someone would file a civil lawsuit against her.

The problem is, there isn’t.

Chen Jiang’s investigation shows the remaining 5 living individuals declare the gifts were voluntary and they don’t intend to take them back.

In fact, these few even stated that Liang Juan could approach them anytime if willing.

Aside from true love, no other words seem adequate to describe this.

"No discovery."

Chen Jiang shook his head, "From the clues currently investigated, Liang Juan and the three suicide individuals had normal romantic relationships."

"As for estates, she truly didn’t want them."

The first time Chen Jiang met Liang Juan, when mentioning estate, the other party appeared surprised.

At that time, she stated she wouldn’t take the property of the three deceased.

"These days, Liang Juan and the children of the three deceased are communicating the related contents of their wills."

"The property, she indeed didn’t take."

This made everyone’s brows furrow deeper.

If you say Liang Juan dated these people purely for money, there’s no need to refuse the properties at hand.

After all, Wang Gang and the others’ wills explicitly offer all properties to Liang Juan.

Although they are wealthy, the value of these properties is not low; combined, they add up to seven properties.

The total value exceeds 20 million.

This is not a small amount.

"So if the deaths of these three people are related to Liang Juan, the motive doesn’t hold now, does it?"

Lu Chuan isn’t concerned if it’s fraud, but he wants to clear if these three deaths are normal.

What role exactly did Liang Juan play here?

Is there any element of incitement involved?

But looking at it now, it seems Liang Juan has no motive to incite the trio to suicide.

"Personally, I think... no."

This is Chen Jiang’s judgment.

No...

Phew...

"But I have a doubt."

Lu Chuan spoke up, catching everyone’s attention.

"Firstly, the suicide method of the three deceased."

"Chen, show the photos inside the deceased’s car."

The projector displayed photos taken after the deaths of the three deceased.

"Although all three deceased were romantically involved with Liang Juan, they did not know each other."

This point is confirmed.

There are no records of communication or transaction exchanges between the three deceased.

Wang Zhaokai confirmed this while investigating the background relationships of the three deceased; their children also reflected mutual unfamiliarity.

"Three people who don’t know each other all chose charcoal suicide."

"However, charcoal burning suicide... not seen in years."

"All carbon monoxide poisoning cases are accidental, not suicides."

"But these three chose the same method; is it coincidence?"

"Absolutely not!"

Lu Chuan’s judgment was absolutely not.

If all three chose to jump off a building, it might still make sense, but to adopt a suicide method never before used...

One instance could be plausible.

If all three are the same, Lu Chuan doesn’t believe it!

To Lu Chuan’s judgment, everyone exchanged glances, acknowledging its plausibility.

"I think Captain Lu is right."

Someone expressed a view, "Carbon monoxide poisoning cases were more common before renovations; when households used coal stoves."

"But small coal stoves have long been phased out over the past decade, so carbon monoxide poisoning is rare."

"Cases of deliberate charcoal burning in cars to create a carbon monoxide environment for suicide have not appeared before."

"No, it’s not that they haven’t appeared, just not domestically."

Lu Chuan continued, "Chen, turn the PPT to the last page."

"Look, these are some materials on charcoal suicide I found in recent days."

"Not many domestic cases, but more abroad."

"Especially in some western countries, the proportion of car charcoal suicides is relatively high."

The projector displayed data and image materials. After viewing, someone raised a question.

"Captain Lu, do you mean they might have learned this suicide method through some means or approach?"

Lu Chuan nodded.

"That possibility exists."

"But I lean towards someone inciting or assisting in their suicides, as the possibility they chose this method merely through films or materials is extremely low."

"From the investigation results, the only link between the three is Liang Juan."

Clearly, Lu Chuan still suspects a connection between Liang Juan and the trio’s deaths.

"One last oddity concerns the locations of the suicides."

The projector photos shifted to wide shots of the suicide sites.

These are surveillance captures Lu Chuan requested.

"The three deceased not only used the same suicide method but also chose monitored parking lots."

"If their method was self-taught online, they stumbled upon a low-probability coincidence; what about the choice of location?"
