In the office.

Director Li, upon hearing Guan Feng's words, did not deny them, but instead explained, "Tan Kai was assigned to our institute right after graduation, but how should I put it? I have seen his work attitude, especially his love for learning and his ability to learn."

"Ever since Captain Guan sent the micro-expression analysis video to all the grassroots stations in Hua'an, he has been studying it diligently, sometimes staying up all night in his dormitory to watch it."

"If he has the opportunity to be transferred to the criminal investigation team, I think it would be a good thing for both the criminal investigation work and his personal development."

That's almost a very high compliment!

Guan Feng nodded and looked at Director Li, asking, "Does Tan Kai have any tasks today? We're investigating village affairs and we're looking for someone who knows about them."

Director Li said, "No problem! There's nothing going on at the station, and besides, we can handle any problems that do arise."

Guan Feng then turned to Tan Kai and asked, "Tan Kai, how's things going on your end? Would you be willing to investigate this case with us?"

Tan Kai was certainly willing!

Not only were they willing, but it was an unexpected delight.

This is investigating a case with my idol whom I've admired for so long!

He nodded excitedly and said, "I've been dreaming about this!"

Seeing Tan Kai's excited expression, Director Li laughed heartily, and Guan Feng and Huang Lili also smiled.

Guan Feng then instructed, "In that case, we'll temporarily transfer Tan Kai today. Lily, call Zou Qian and tell her that we need to add someone to the micro-expression analysis assessment. Tell her to prepare the application."

Huang Lili said, "Okay, Captain."

After Huang Lili finished her call, Guan Feng shook hands with Director Li to say goodbye, and the two of them took Tan Kai back to their car.

Tan Kai was still a little reserved, so Huang Lili reminded him, "Tan Kai, don't be nervous. Our captain is very easygoing. Don't feel any pressure. Just show your normal qualities and state."

Tan Kai said, "Okay, I'll try my best."

Guan Feng then reminded her, "Lily, drive to the traffic control center. I'll contact the person in charge here in Liancheng."

......

Ten minutes later.

When the vehicle arrived at the Liancheng Traffic Command Center, the person in charge from the Liancheng Bureau was already waiting downstairs outside the command center.

He saw Guan Feng get out of the car and immediately went up to him, smiling and saying, "Captain Guan, right?"

Guan Feng nodded and said, "Hello, Section Chief Zhang! And these two are..." He briefly introduced Huang Lili and Tan Kai, and then said, "We're here mainly because of a murder case, and we need to retrieve the driving trajectory of a van."

Manager Zhang hurriedly said, "No problem! Come with me, our people are ready."

The group entered the command center and went directly to the lobby.

The relevant footage is being monitored in real time on all roads.

Several figures sat there monitoring.

The person in charge, Zhang, said, "Xiao Liu, come here! Cooperate with Captain Guan to do a good job of retrieving the data."

A young man in his twenties walked over, looked at Guan Feng, and said, "Captain Guan, hello. What do you need me to retrieve?"

Guan Feng took the license plate number from Huang Lili and said, "We need to retrieve the information about this vehicle."

The young man immediately took the license plate number, entered the relevant number, and started searching.

After a moment he said, "This is the usage trajectory of this car during this period, but the other party's vehicle has not appeared in the surveillance footage since five days ago."

Guan Feng asked, "Does this mean the other party hasn't opened it again?"

The young man shook his head and said, "Our surveillance system only has cameras on main roads and major thoroughfares that are connected 24 hours a day. Some cameras on smaller roads may not be connected, so he might have been driving on a smaller road and not been caught on camera, or he might have been caught but the footage wasn't transmitted."

Guan Feng nodded and said, "In that case, please help me retrieve the last scene of him appearing."

The young man began to retrieve the footage.

A silver van appeared, drove on the road, and then disappeared.

Guan Feng asked, "How far is this road from Xiaowang Village?"

"Xiaowang Village?"

The young man frowned slightly.

Tan Kai then reminded him, "Captain Guan, this road should be in Meihe Town. Xiaowang Village is in Meihe Town, so the distance between the two shouldn't be too far, maybe three to five kilometers at most."

Guan Feng nodded and said, "In that case, we should still follow this path to search."

He looked at Huang Lili and said, "Lili, copy this time period down."

"receive!"

Huang Lili immediately stepped forward and started copying.

Guan Feng then looked at the young staff member and asked, "What about this side? If the other party continues to drive forward, where are the surveillance cameras ahead?"

The young staff retrieved the relevant intersection camera footage.

Guan Feng opened the relevant map and found that the surveillance camera was at the end of the road. However, the map also showed that there were two other intersections. Guan Feng said, "There are no surveillance cameras on these two side roads, right?"

The young staff member nodded and said, "Yes, this is the path I was talking about. It's usually not used by many people, and it's a dirt road, so our surveillance cameras don't cover it."

Guan Feng nodded and looked at Huang Lili and Tan Kai, saying, "The situation is quite clear now. Whether the other party's vehicle disappeared in this area or left through a side road, we need to go to the scene to investigate."

"Get ready to go! Let's see what's going on!"

"receive!"

"receive!"

Huang Lili and Tan Kai both nodded.

The three returned to the car and, led by Tan Kai, arrived at the road.

Guan Feng frowned as he looked at the tire tracks on the road and said, "This road is usually used by many cars. It's probably not going to be easy to find tire tracks here."

Tan Kai asked, "Captain Guan, do you also have expertise in tire rut identification?"

Before Guan Feng could answer, Huang Lili said directly, "Trace evidence identification is a matter of general knowledge. Captain Guan even understands footprint identification, so wheel rut identification is definitely no problem for him. The clue in the last case was found by investigating wheel ruts!"

The admiration on Tan Kai's face became even more evident.

Guan Feng waved his hand and said, "Keep driving forward! Until you reach the first fork in the road."

Huang Lili continued driving and arrived near the first fork in the road.

Guan Feng asked Huang Lili to stop the car and observe the relevant tracks along the fork in the road. The road at the fork was a dirt road, and since it had just rained last week and it was winter, there was still some mud on the ground, which made the tire tracks very obvious.

The tracks of both bicycles and tricycles were clearly visible to Guan Feng, but he could not see a single tire track from a motor vehicle.

He looked at Huang Lili and asked, "What day was it last week that it rained?"

Huang Lili said, "It's Wednesday!"

Guan Feng nodded and said, "That was six days ago! That just covers the surveillance footage from this time."

Huang Lili said, "According to the timeline, yes."

Guan Feng stood up and said, "There are no tire tracks on this side road. Let's go and check the next side road."
