The process of arresting Wang Junshan went very smoothly. Zhang Hui and his team didn’t encounter any resistance while arresting Wang Junshan in his current rented house.

"You must have made a mistake, right?"

"I haven’t seen Zhang Xiaotian for more than half a year, how could I kill him?"

Wang Junshan was livestreaming when he was arrested.

Moreover, with his makeup, long flowing hair, and red lips in a long dress, he could easily pass for a real woman.

"If you don’t believe me, you can check my livestream records. I’m livestreaming 24/7 now, even while eating and sleeping, and my fans can prove I haven’t left anywhere."

Outside the Criminal Investigation Team’s interrogation room.

Zhang Hui frowned at the footprint comparison report in his hands: "It doesn’t match?"

Lu Chuan nodded: "Although Wang Junshan wears size 43 shoes, the footprints at the crime scene are slightly wider in the forefoot and have a different center of gravity. I’m certain the footprints at the crime scene are not his."

Zhang Hui opened his mouth, thinking about whether the other party might have used some kind of trick, but remembering Lu Chuan’s expertise in footprint identification and analysis, he knew if the footprints were indeed left by Wang Junshan, they wouldn’t escape Lu Chuan’s examination.

But if it’s not him, then who could it be?

At this time, the criminal officer who reviewed Wang Junshan’s livestream video also returned.

"We’ve figured it out. Wang Junshan has been livestreaming since half a year ago, his livestream runs 24 hours a day. From 3 to 4 AM today, he was livestreaming himself sleeping in his rental apartment, so he had no time to commit the crime."

"Additionally, there’s surveillance at the entrance of Wang Junshan’s unit. Song just reviewed the footage for the time of the crime, and only a delivery guy was seen entering. Wang Junshan should not be the murderer."

It’s not him...

If it’s not him, then who else could it be?

"What about the DNA analysis? Are the results out yet?"

"Not yet, it should be completed tonight."

"Alright, we’ll wait for your results, I’ll have another chat with Wang Junshan to see if there are any other clues."

In the interrogation room, Zhang Hui questions Wang Junshan.

"Mr. Wang, when we mentioned Zhang Xiaotian’s death at your place, you didn’t seem very surprised."

Earlier, in Wang Junshan’s rented apartment, Zhang Hui was almost certain for a moment that Wang Junshan could be the murderer.

Even though he seemed shocked by the police’s presence, he did not appear surprised at all about Zhang Xiaotian’s death, as if he had known beforehand.

A death, especially a murder, is something that hardly leaves anyone indifferent.

Especially when it’s someone you know; upon hearing they’ve been murdered, Wang Junshan’s lack of surprise was certainly suspicious.

"What’s there to be surprised about? I had told Zhang Xiaotian early on that he would eventually die in that place."

"Oh, and why do you say that?"

"I’ll tell you, where we used to live was cursed. When I lived with Xiaotian last year, I felt something was wrong. Early this year, I told him to move out, but he refused, and we eventually broke up."

"You broke up over this?"

"Exactly. I’m telling you, they were all crazy, they’d all end up dead there sooner or later."

"Can you tell us more about it?"

"I’m not really sure, but Zhang Xiaotian and the neighbors there seemed to have joined some Mutual Aid Association. They wanted me to join, but I didn’t. He wouldn’t tell me exactly what it was about."

"Does that make sense to you? I was his girlfriend, and he wouldn’t even tell me."

Wang Junshan gestured with a delicate hand, appearing quite upset.

Mutual Aid Association?

"You broke up over this?"

"Not entirely, but close enough, plus he betrayed me once."

Wang Junshan seemed very angry, his voice roughened as he spoke: "He was with that old landlord, damn it, he was with such an ugly old landlord, I was blind to have been with him!"

"Does he think he won’t find true love without me?"

"He must be out of his mind if he thinks that. Since I started livestreaming, I’ve received countless gifts from viewers, all saying I’m beautiful."

"Plus, when I was with him, we were so poor we couldn’t even afford good things twice. Now, I have plenty of money!"

...

9:30 PM, Criminal Investigation Team meeting room.

"We are now holding a case analysis meeting, everyone please report on the progress of your work."

Liu Guodong cleared his throat: "Let me start."

"The investigation and analysis are complete. The causes of death for the four victims have been determined, and the time of death is between 3 AM and 4 AM this morning. After the bloodstains at the scene were collected, we found DNA information from five people."

"In addition to the four victims, there is DNA information from one unknown person."

"There are signs that the killer wiped the blood at the scene. We deduced that the killer must have bled during the struggle, so we can confirm that the unknown DNA belongs to the killer."

"Lu Chuan also found the killer’s footprints at the scene and did a footprint identification and analysis. The killer is approximately 1.78 meters tall and weighs about 70 kilograms."

"Based on the circumstances and the victims’ identities, we initially suspected that Wang Junshan, who roomed with Zhang Xiaotian half a year ago, was highly suspicious."

"But after Wang Junshan was arrested, we conducted a DNA comparison and footprint analysis at noon."

"We excluded the possibility that Wang Junshan is the killer."

Qin Yong glanced at Zhang Hui, who sat up slightly: "After finding Wang Junshan, we investigated his actions during the time of the crime. For the past six months, Wang Junshan has been doing a 24/7 livestream. From 3 to 4 AM today, he was livestreaming himself sleeping, and the surveillance at his rental unit’s entrance shows no signs of him going in or out."

"So this lead is essentially ruled out?"

Both nodded simultaneously.

"Did the DNA identification analysis of the fifth person match anyone in the system?"

Liu Guodong shook his head: "We haven’t found anything. It is likely that the target killer’s DNA was never recorded, but we’ve already asked the task force to collect blood samples from everyone in the rental unit to see if we can find anything."

While the killer hasn’t left a DNA trail in the database, revealing their identity is just a matter of time once they appear.

"The last aspect is fingerprints; we collected some fingerprints from the exterior door at the crime scene, but they belonged to the four victims and the landlord, with no other fingerprints present."

This indicates that the killer must have worn gloves when opening the door.

It’s normal for the victims’ fingerprints to be on the door, and since the landlord reported the crime, his fingerprints being there makes sense too.

"How is the Forensic Doctor doing?"
