Guan Feng briefly recounted what had just happened.

Zhao Dong said, "Your idea is good! But are you sure Wang Hongquan isn't home?"

Guan Feng nodded and said, "He's not home! When I was questioning him just now, I paid special attention to Wang's body language and facial expressions, so he shouldn't be lying."

Zhao Dong said, "Your micro-expression analysis is definitely correct! Now let's wait for the technical department to arrive."

Guan Feng said, "Team leader, I think we should contact Skynet? Although we can't confirm Wang Hongquan's suspicion yet, we can start with an internal investigation. He came back the night before last, and his car happened to be parked in the open space in front of his house. That can't be described as a coincidence, can it?"

Zhao Dong thought for a moment, then nodded and said, "Your consideration makes sense! Let's first determine the approximate location of the person, and then we'll discuss it further once we find more clues."

Guan Feng took out the transparent plastic bag from his pocket: "This is the blood we just extracted from the car." Then, as if by magic, he pulled out two hairs from his pocket and said, "These are the boss's hairs. We'll submit them for testing when the technical department arrives."

Zhao Dong said, "Well done, Xiao Guan, your technique is even better! The boss didn't even feel a thing after you plucked his hair."

Guan Feng said, "I would like to extract Wang Hongquan's hair directly, but unfortunately he is not here, so I can only make do with his father's for now."

As they were talking.

The technical department's vehicle arrived.

An inconspicuous black sedan pulled up next to Zhao Dong's car.

"Team Leader!"

The car window rolled down, revealing Old Wang's face.

Zhao Dong handed over the bag containing the bloodstains and said, "Let's test these few drops of blood first. We've already identified Shi Juan's DNA, right? Let's confirm whether these drops of blood belong to her!"

"Also, take another spot check on these two hairs and compare them with the marks on the car."

Old Wang from the technical department immediately said, "Okay! I'll arrange for someone to test the bloodstains right away, and I'll personally go and collect the traces from the car."

Zhao Dong said, "Be careful!"

Old Wang said, "Don't worry, Captain, it's broad daylight, who could possibly be there..."

Guan Feng added, "The suspect may be lying in wait nearby. The team leader means that he hopes you can narrow down your target and try to avoid being discovered."

Old Wang said, "Is that so? Then I'll close the door and check it after I get in the car."

Guan Feng asked, "Won't there be any problems with this?"

Old Wang said, "Except for the fact that people feel a bit stifled, there won't be any blind spots."

Guan Feng said, "In that case, I'll take you there. Captain, shall I go over there myself? Just in case someone's watching."

Zhao Dong nodded and said, "Be careful."

Guan Feng then led Lao Wang from the technical department to the vicinity of the vehicle.

The same old trick again!

He turned on his smart glasses, made sure no one was watching the vehicle's location, then arranged for Lao Wang to get in the car and begin checking for vehicle tracks. He, meanwhile, stood guard at the entrance of the alley, observing pedestrians and keeping an eye on the vehicle's movements to ensure Lao Wang's safety.

About twenty minutes later.

His phone rang.

Connected!

However, Lao Wang had already checked the vehicle's traces and extracted relevant fingerprints, hair, and other items from inside the car.

Guan Feng immediately stepped forward to assist him.

Five minutes later, the two returned to the technical department's vehicle.

By this time, the first batch of results from the technical department had been released. After comparison, the bloodstains on the vehicle matched the DNA from the hair samples extracted from Shi Juan's home.

In other words, the bloodstains most likely belong to Shi Juan.

Upon hearing this news, Zhao Dong and Guan Feng both frowned.

Blood!

This is a further deterioration from the previous situation.

Zhao Dong immediately said, "Xiao Guan, call Liu Keming and tell him about this! Lao Wang, immediately test the extract from this car to see if it matches Wang Hongquan's DNA!"

"receive!"

"receive!"

Both of them nodded seriously and got to work.

Guan Feng then dialed Liu Keming's number in front of Zhao Dong, telling him that he had found the black car with the license plate ending in 857 and that he had also extracted Shi Juan's blood from the back seat of the car.

Liu Keming was also surprised when he heard the news, and subconsciously asked, "Did the comparison really succeed?"

Guan Feng nodded and said, "The comparison is successful! Unless the hair extracted from Shi Juan's home is not left by Shi Juan, she must have been in the car and was injured."

Liu Keming's heart skipped a beat, and then he said, "I understand! I also wanted to tell you about the situation here. We investigated Shi Juan's interpersonal relationships in detail and found that her social interactions are very simple. Apart from going to and from get off work, she stays in her rented room. She had a boyfriend before, but they broke up three months ago. Through the comparison of her whereabouts, we found that he did not have the time to commit the crime."

"We're still checking the surveillance footage, but it's taking a lot of manpower. We haven't found any specific suspects yet. We'll contact you again if there's any news."

Guan Feng said, "Okay, I'll send the car back after I'm done here. Then we'll merge and conduct a comprehensive inspection."

Liu Keming said, "Okay."

After hanging up the phone, Guan Feng reported the progress made by Captain Liu Keming to Zhao Dong, and said, "Captain, if the traces found in the car match Wang Hongquan's, then we will immediately activate Skynet and investigate his whereabouts."

Zhao Dong nodded and said, "That's only right!"

Guan Feng added, "There's one more thing. We were worried about alerting the car owner, but now that the owner has called the police, we can use that as a reason to take the car back."

Zhao Dong said, "You're absolutely right. Let's do it your way."

Guan Feng nodded, got into the car, took a sip of water, and waited patiently with Zhao Dong for the results from the technical department next door.

Ten minutes later.

Just as the air seemed to become oppressive, news came from the technical department: through technical comparison, the hair, dander, and other tissues they found in the vehicle came from four people, and the DNA of one of them was a perfect match for the two hairs that Guan Feng had sent.

In other words, there is a physiological relationship between the two!

Guan Feng and Zhao Dong's expressions both changed.

Old Wang then asked, "Squad leader, what should we do now?"
