"Or rather, did we really overlook some key clues in the preliminary screening process?"

Suddenly, he recalled a detail mentioned by Li Changhe—their village had registered nearly tens of thousands of people during the population census five years ago.

In such a time of frequent population movement, is there a potential relationship network that we have yet to grasp?"

For a moment, he felt his temples pulsating, as if countless fragments were swirling and colliding in his mind.

Wang Yang calmly spoke into the phone, "Okay, since you are so certain about the situation at the scene, this information is very important to us."

"Continue to maintain the site closure, and I will immediately arrange for technical personnel to conduct further investigations."

After hanging up the phone, he stood still by the corridor window for a long time.

At this moment, his brain was working at high speed, trying to sort out a clear thread of logic amid the complex clues.

Through Jiang An's latest site analysis, the two key suspects they had previously targeted were ruled out from being possible perpetrators, a result that was both surprising and unsettling.

"Where is the real perpetrator hiding?"

"Why can they still remain elusive despite the all-encompassing investigation?"

"Has our investigation direction deviated, or is the perpetrator more cunning than we imagined?"

The call from Jiang An regarding the determined location of the traffic accident provided him with new insights.

That seemingly ordinary traffic accident scene could very well be the crucial key to unraveling the mystery of the entire case.

Various signs indicate that the traffic accident is intricately linked to the deceased's bizarre death.

Thinking of this, Wang Yang subconsciously clenched his fist, took a deep breath, and walked forward with determination, reaching out to push open the heavy soundproof door of Interrogation Room No. 1.

In the interrogation room, Zhou Yong was launching an offensive with his signature fierce style.

He leaned his body forward, hands on the interrogation table, his sharp gaze tightly locking onto the suspect across the table, "Wang Ming, I advise you not to harbor any more delusions!"

"Confessing now can still fight for leniency!"

However, no matter how much he pressured, Wang Ming consistently repeated the same sentence mechanically, "I'm innocent, I want to get out early."

Wang Yang moved calmly next to Zhou Yong, gently patting his shoulder.

At the moment their eyes met, years of tacit understanding allowed Zhou Yong to immediately grasp his partner's intentions.

He put away the notebook on the table, signaled the recorder beside him to pause, and then followed Wang Yang out of the interrogation room.

In the corridor, Wang Yang silently paced for a few steps, eventually stopping by the fire hydrant.

He turned around, his face solemn, and said to Zhou Yong, "Mr. Zhou, we may need to rethink the entire investigation direction."

"Direction wrong?"

"What makes you say that?"

Zhou Yong's brows instantly knitted into a knot, his face full of disbelief.

For this case, they burned countless midnight oil, retrieved a vast amount of surveillance footage, interviewed numerous individuals, each investigation step was meticulously scrutinized.

From timeline to spatial trajectory, all evidence chains were perfectly aligned, how could there suddenly be a directional error?

Seeing Zhou Yong's agitated reaction, Wang Yang nodded in understanding,

He immediately detailed, "Just now, Jiang An made a major discovery while inspecting the scene."

"In the woods near where Luo Xi disappeared, they found very noticeable vehicle collision marks."

"Didn't this perfectly confirm our previous deductions?"

Zhou Yong eagerly interrupted, "After the traffic accident, the body was transported over a long distance, this mode of operation perfectly fits the behavioral pattern of a serial killer!"

Wang Yang gestured for calm and continued, "The issue lies in the significant discrepancies between the collision marks they found and our expected situation."

He pulled out his phone and brought up the site photos Jiang An had just sent over, "

Look here, technical personnel have measured that the lowest point of the collision impact is only 20 centimeters above the ground, clearly lower than the chassis height of a typical car."

Zhou Yong leaned closer to the screen, his expression gradually shifting from confusion to shock.

Wang Yang then analyzed, "More critically, according to the site inspection, the culprit's vehicle maintained extremely high speed when veering off the road and hitting the trees."

"The strong impact force led the chassis to neatly slice through the grass on the ground, forming special shear marks."

"These mark characteristics completely contradict the type of vehicle we initially speculated."

Upon hearing this, Zhou Yong frowned.

As a forensic investigator, though primarily handling anatomical work, he has been involved in numerous traffic accident site investigations over the years.

Wang Yang's words flashed countless possibilities in his mind, "Your meaning is... it's not a large truck?"

Wang Yang slowly nodded.

Zhou Yong's breathing became heavy.

Although he hasn't handled many traffic accident cases, he is versed in basic investigation principles.

He involuntarily stroked his stubble and asked, "At the site... besides the obvious collision marks, are there any other suspicious traces?"

"Or rather, is there some kind of connection between this accident and the case we are investigating?"

Wang Yang stood, paced to the window, and with his back to Zhou Yong said, "I have repeatedly considered this possibility just now."

"Although Jiang An mentioned finding only one collision mark over the phone, but..."

He turned around, his eyes sharp, "We cannot rule out the possibility of other vehicles passing by beforehand."
