Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Lu Chuan gave his reasons, but this was not evidence.

Lu Chuan's speculation was actually from the perspective of the murderer.

If Lu Chuan was the murderer, how could he transport carbon monoxide into the car without being discovered? This was the only way he could think of.

It's called the supposed murderer.

"Lao Lu, let's assume that your guess is correct, but who can open Wang Chuanzhi's trunk without his knowledge."

"You even have to do some tricks inside and put in a carbon monoxide gas generating device?"

The question raised by Zhang Hui is actually very clear and directional.

The relative must be someone very close to Wang Chuanzhi.

Otherwise, how could the other party open the trunk of Wang Chuanzhi's vehicle.

"Also, is the carbon monoxide gas generating device you mentioned... difficult to make?"

Two questions.

There are two problems with Lu Chuan's guess.

The first is who can open the trunk of Wang Chuanzhi's car without alerting him.

During the on-site inspection, we found no signs that the vehicle had been broken into, and the locks were intact.

The trunk of the vehicle driven by the deceased Wang Chuanzhi could only be opened with a key.

Or open it through the trunk unlock button in the driver's seat.

But no matter which one, either the other party is proficient in unlocking, just like Lu Chuan found the locksmith and opened the car door in a few clicks.

Or have the keys to the vehicle.

Second, the carbon monoxide generating device...

What is this stuff?
"The device is quite simple."

Lu Chuan said: "The so-called carbon monoxide poisoning refers to other gases besides oxygen, such as liquefied gas, coal gas, natural gas, etc."

"An ordinary liquefied gas tank can do it."

In fact, gases such as liquefied petroleum gas themselves have no taste.

The liquefied gas we often smell has aromatics added during the processing process, so that it can be detected when it leaks and avoid poisoning.

"As long as someone has a little knowledge of chemistry, it is not difficult to prepare carbon monoxide gas."

"Do you still mean to focus on the two deceased people, especially Wang Chuanzhi's relatives?"

Zhang Hui understood what Lu Chuan meant.

The murderer was able to open the trunk and place carbon monoxide without disturbing Wang Chuanzhi, which means that the murderer knew Wang Chuanzhi.

And the relationship is so close that at least he can get Wang Chuanzhi’s car keys.

Lu Chuan nodded: "I feel like we still need to investigate further."

"Of course all this assumes that our guesses are correct."

"I think we can push ahead with Director Lu's idea."

Some people agreed with Lu Chuan's opinion.

"Yes, there was an extramarital affair between the two victims."

"Although the current investigation shows that the relationship between the two victims and their families is good, this is only a one-sided statement."

"No one can be sure whether the husband and wife of both parties knew about the relationship between the victims."

Someone else agreed with Lu Chuan's proposal.

"Zhang Hui, how is your investigation going?"

Qin Yong did not express his position, but turned his head to look at Zhang Hui.

After the incident, the action team was responsible for investigating the interpersonal relationships between the two victims. Zhang Hui personally inquired about the wives and husbands of Wang Chuanzhi and Zhang Cuilian.

Lu Chuan returned to his seat from the projection screen, ready to listen to Zhang Hui's investigation.

What we are doing here is just evidence analysis.

Lu Chuan, Yang Lin, Yang Sen and others came up with conjectures about the current investigation based on some inspections of the deceased's vehicle.

This is just one possibility for the development of the case.

But whether the truth is really like this remains to be investigated.

"After the incident, the identities of the two deceased persons were confirmed, and we notified the families of the victims as soon as possible."

Zhang Hui began to report the situation: "The deceased Wang Chuanzhi's family is local, and his wife is also in Haizhou City. This morning, we questioned Wang Chuanzhi's wife Xu Qianqian."

"Our focus here is to learn about Wang Chuanzhi's personal situation from Xu Qianqian, as well as some information about Xu Qianqian herself."

"Let's talk about Xu Qianqian first. Because of the extramarital relationship between Wang Chuanzhi and Zhang Cuilian, Xu Qianqian is our key suspect."

"Although Xu Qianqian denied that he knew about the relationship between Wang Chuanzhi and Zhang Cuilian, we still investigated her whereabouts."

"The deceased Wang Chuanzhi left home for the company at 17:7 am on the 00th."

"This is the last time Xu Qianqian sees Wang Chuanzhi."

"We have checked the surveillance at the entrance of Wang Chuanzhi's residential area."

"Look, everyone," there was a photo on the projector, "This is a screenshot of the video taken by the surveillance camera at the gate when Wang Chuanzhi's vehicle left the community in the morning."

"It can be clearly seen from here that Wang Chuanzhi was the only one in the car."

"Later, we also conducted an investigation into Wang Chuanzhi's company."

"The time when Wang Chuanzhi's car entered the company's underground parking garage was 7:28."

"This time is exactly the approximate driving time from his home to the company."

"And we checked Wang Chuanzhi's call records during this journey. No one called him, and he never made any calls."

"After that, Wang Chuanzhi stayed in the company until he left the company at 6:30 p.m."

"An investigation of the call records and chat records on Wang Chuanzhi and Zhang Cuilian's mobile phones shows that they made an appointment to meet tonight at 11 a.m. the day before."

"At 6:00 p.m., Wang Chuanzhi called his wife Xu Qianqian and said that he had a social event in the evening."

"After that, he left the company and went directly to the entrance of the Municipal Public Security Bureau community."

"During this period of time, Xu Qianqian has been at home and has not gone out."

"This is an internal surveillance video of the community. On the day of the incident, Xu Qianqian went downstairs three times."

"One time I went out to take out the trash in the morning."

"Another time I was walking my dog, but it stayed in the community and didn't come out. It was captured on surveillance cameras many times."

"The last time I went downstairs was about three o'clock in the afternoon."

"This time she left the community and went to the supermarket at the door to buy groceries."

"We checked the surveillance and her payment records."

"After that, Xu Qianqian stayed in the community until this morning, when we informed her of Wang Chuanzhi's death."

"The entire time chain is complete. Xu Qianqian did not leave the community. Therefore, judging from the current investigation results, Xu Qianqian did not commit the crime."

The investigation of the second operation team can be said to be very detailed.

Because of the special relationship between the two deceased persons, Wang Chuanzhi and Zhang Cuilian, during the investigation, the second operation team first targeted the wives and husbands of the two deceased persons.

As for Wang Chuanzhi's wife, Xu Qianqian, her time in the community is continuous.

It can be said that there is a sufficient alibi. (End of chapter)
