Diary of a Criminal Investigator

Chapter 911: Confess Within Twenty Minutes or Lose Your Chance

Although he added the last sentence, giving a limiting condition, this is undoubtedly the most important clue currently in the case.

Of course, theoretically, the fingerprint on the twig may not necessarily be left by the suspect, for example, it could be left by the person who retrieved it or broke it off.

Wang Song chimed in, "I think we should first collect Li Baowei’s fingerprints for comparison."

From yesterday until now, in order not to alert the suspect, both Wang Song’s team and Song Mingguang’s team have conducted their investigations in secret, avoiding any direct questioning of Li Baowei.

Since fingerprint comparison is now possible, we can directly collect the fingerprint.

Although the other party has an alibi, what if it’s fake?

After Lu Chuan reported his findings, the other teams also made corresponding reports.

Li Donglin’s team focused on listening to reports on the video investigation about Wang Jingya’s disappearance.

This work is mainly conducted by the Tianzhou City Criminal Investigation Team because it involves cooperation with the local traffic police.

Wang Chuanmin has been running around for this matter.

"The street where Wang Jingya went missing has heavy traffic. That night, we conducted a thorough investigation of the vehicles passing by this stretch of road."

Wang Chuanmin turned on the projector, displaying a set of data.

"First, we speculate whether the suspect followed Wang Jingya to the vicinity of the Chenyang District or if they were just there all along."

"If the suspect was always there, then where did they park their car?"

Since yesterday, after Li Donglin reviewed the scene and made arrangements, Wang Chuanmin has done a lot of work.

"We checked the parking conditions nearby. This road is not a heavily regulated area; parking is possible along the street, and there are no large parking lots around, only the underground parking garage or the courtyard of the district where vehicles can be parked."

"If the suspect was waiting for Wang Jingya there, then they likely parked their car on the roadside."

Wang Chuanmin stood up, "We investigated all vehicles parked for a long time on the target road that day."

"So far, we have found the owners of all parked vehicles, a total of twenty-eight people, and the investigation results show that they have no connection with Wang Jingya."

"Next was the investigation of moving vehicles after the time frame when Wang Jingya went missing."

Wang Chuanmin flipped through the presentation, showing surveillance footage of a white Volkswagen sedan.

"Based on the time Wang Jingya exited the taxi as the starting point, up to 9:30, we conducted a thorough investigation of all moving vehicles passing through the road."

"We found something interesting here."

Wang Chuanmin focused on introducing the white Volkswagen sedan in the presentation.

"The owner of this car is Qin Jianshe, but the vehicle is actually used by her daughter, Qin Xiaohui."

"Qin Xiaohui?"

Li Donglin frowned, "Was she the one who had dinner with Wang Liya the night she went missing?"

Wang Chuanmin nodded, "That’s right."

"After Wang Liya went missing, we conducted an investigation and learned from Qin Xiaohui that she and Wang Jingya had a meal together, and they ate Japanese cuisine."

Wang Chuanmin quickly introduced the situation, "According to Qin Xiaohui, the dinner appointment with Wang Jingya was set three days in advance."

"After the two had dinner, Wang Jingya took a taxi, following the arrangement, and headed to Chen Yang’s place."

"But why did Qin Xiaohui’s car also appear near that district?"

"Personally, I think this is suspicious, and Qin Xiaohui is likely not telling the truth."

Wang Song’s team, Song Mingguang’s team, and Wang Chuanmin’s team all made progress in the vehicle investigation.

All three teams have identified some individuals of suspicious value.

And now, it seems, Li Baowei and Qin Xiaohui are the most suspicious.

Firstly, although Li Baowei has an alibi, his height matches Lu Chuan’s assessment, and from the perspective of motive, he has the strongest motive to kill.

The other suspect is Qin Xiaohui.

Regardless of whether she is involved in Wang Jingya’s disappearance, she at least did not fully disclose the truth during the police questioning.

According to Qin Xiaohui, after the two finished dinner, Wang Junya took a taxi to Chen Yang’s place, and she left.

However, Wang Chuanmin discovered her vehicle appearing near the entrance of Chenyang District in the surveillance footage.

Precisely during the time frame when Wang Jingya disappeared.

"Immediately summon these two individuals."

With suspicion, further investigation is warranted.

Li Donglin decisively instructed, "Lu Chuan, keep a close eye on the fingerprint matter."

"Understood."

One hour later.

Li Baowei and Qin Xiaohui both appeared in the interrogation room of the Tianzhou City Criminal Investigation Team.

"I’m really not lying. Wang Jingya took a taxi that day and left, like I said, she went to Chen Yang’s place. You should ask Chen Yang."

Chen Yang?

The interrogation of Qin Xiaohui was conducted by Wang Chuanmin, who personally stepped in this time.

Wang Chuanmin picked up a photo from the table and asked his assistant to hand it to Qin Xiaohui, "Do you know what this is, Qin Xiaohui?"

"This is a screenshot captured by the road surveillance camera at the entrance of Chenyang District of your vehicle on the night Wang Jingya disappeared at 9:12 PM."

Screenshot?

Upon receiving the photo, Qin Xiaohui’s complexion changed instantly.

"Don’t think that just because this car is registered under your father’s name, we can’t trace that it was actually you driving it there."

Before becoming the leader of the Criminal Investigation Team, Wang Chuanmin was one of Quanzhou City’s Public Security Bureau’s best pre-trial investigators.

His interrogation style is steady and compelling.

He makes those being interrogated feel like they are facing a mountain, with time, breathing becomes harder under the pressure.

"I... I didn’t..."

"I advise you to think carefully before you speak!"

Wang Chuanmin directly interrupted Qin Xiaohui.

"You haven’t been truthful with the police, and now we have every reason to suspect that you are directly connected to Wang Jingya’s death."

Wang Chuanmin’s voice was low and serious, "I should also inform you, we’re currently using the traffic police’s surveillance system to track your vehicle’s trajectory."

Wang Chuanmin glanced at his watch, "In about twenty minutes at most, all of your vehicle’s movements from that night will be fully and clearly investigated."

"Also, some high-definition surveillance cameras can clearly capture who is in the driver and passenger seats."

"Qin Xiaohui, you still have a chance to confess, twenty minutes!"

"Before I receive the report of your vehicle’s driving trajectory and the photos taken by high-definition surveillance cameras, I consider your confession frank."

"After this time point..."

Wang Chuanmin sighed, "You won’t have another chance!"
