Chapter 191 Monitoring

"Can evidence speak for itself?"

Bai Mengfei chuckled and stepped forward. "Don't joke around. These pieces of evidence are nothing special. Even I couldn't find any valuable clues in them. What can you possibly figure out?"

“I can deduce the killer’s psychology from these physical evidences. Don’t forget, I have quite a bit of knowledge about psychology.”

Xiang Yuntian laughed heartily and said, "From your analysis of the physical evidence, I found many contradictions. So I have an idea that these pieces of evidence were very likely left behind by the murderer to disrupt our investigation."

Bai Mengfei suddenly felt that Xiang Yuntian's words made a lot of sense. She frowned slightly, nodded gently, agreed with his point of view, and said with interest, "Go on."

Xiang Yuntian slowly stood up and continued, "Besides what we've already investigated, there are no other obvious physical evidence or traces at the scene. This, however, leaves the most obvious psychological traces. This is enough to prove that the murderer was extremely meticulous and highly intelligent. He must have been exceptionally calm while committing the crime. Otherwise, how could he have fabricated such clues after killing someone?"

“But these are just your deductions,” Bai Mengfei retorted.

Xiang Yuntian smiled and said, "So you don't believe my deduction, but believe these pieces of evidence more? Actually, I've handled those physical evidences of yours."

"You've been in contact with them?" Bai Mengfei asked in surprise.

Xiang Yuntian nodded affirmatively and said, "That's right, and you've overlooked a rather common-sense issue."

"What's the problem?" Bai Mengfei asked curiously.

Xiang Yuntian smiled confidently and said, "Did you notice that there were no fingerprints on that cigarette butt? But normally smokers would use their hands to pick up cigarette butts. Also, look here, there's no ash."

After hearing what Xiang Yuntian said, Bai Mengfei took a closer look and found it to be true.

"Oh, I see. This means that the cigarette butt was picked up from somewhere else and deliberately thrown here, right?"

“Absolutely correct.” Xiang Yuntian snapped his fingers and confidently crossed his arms. “That’s why I said this murderer is very intelligent and extremely calm. This suggests that he may not be a first-time offender; he might even have a criminal record.”

Bai Mengfei felt that Xiang Yuntian's words made sense, so she lowered her head, listened attentively, and thought carefully.

After thinking for a while, she was still a little confused, so she asked, "Then how do you explain the fact that the female victim bit her tongue when she died?"

“I’ve thought about this for a long time and still can’t figure it out. But you might want to think about it: if you connect this matter with what happened before she died, maybe you can find the answer.”

"Could it be that someone else in the restaurant that day experienced similar treatment, so..."

Bai Mengfei suddenly had this speculation.

Her speculation gave Xiang Yuntian a lot of inspiration.

Xiang Yuntian suddenly said excitedly, "That's right! How come I didn't think of that before? Now that you mention it, I suddenly feel that it's very likely. Anyway, the possibility is quite high. How about this, let's go to the restaurant now and check the surveillance footage? Anyway, the surveillance video shouldn't have been deleted yet."

Bai Mengfei agreed, and the two drove back to the restaurant where they had been staying that day.

There were still customers in the restaurant at the time. When the waiter heard that the two were public officials and were there to investigate a case, he played the surveillance footage from that day for them.

Xiang Yuntian felt the playback speed was too slow, so he said, "Turn it to double speed."

Then it was adjusted to four times speed and then eight times speed.

His eyes were sharp as he carefully searched through the rapidly passing crowd.

After examining the footage carefully for a while, he suddenly shouted, "Stop, rewind, please zoom in on the middle-aged man in the red plaid shirt."

The waiter did as instructed, while Bai Mengfei watched intently with wide eyes.

The man was bumped by the female victim as he entered the room, and then he walked in.

After entering, his gaze remained fixed on Lü You.

"Did you notice?" Xiang Yuntian suddenly asked.

Bai Mengfei didn't understand Xiang Yuntian's meaning and asked in confusion, "What did you find?"

"Didn't you see that man staring at Lü You? Maybe that's why he helped Lü You kill someone? Although I can't be sure, my intuition tells me that this man is suspicious."

At this moment, the waiter suddenly said, "I remember this man. He paid with WeChat QR code before, so it's not difficult to find his information."

Seeing the waiter's enthusiasm, Bai Mengfei quickly thanked him.

Subsequently, with the help of the waiter, Bai Mengfei and Xiang Yuntian easily found out the man's information.

His name is Feng Biao. He has a criminal record, and the case he was involved in before was the murder of his wife.

He killed his wife in a fit of rage after discovering her affair, and then turned himself in to the police.

Seeing that he behaved well in prison and showed remorse, the judge and prison guards released him ahead of schedule.

Previously, forensic experts had also conducted psychological and work capacity assessments on him, confirming that he was psychologically normal and possessed the legal capacity to work.

After learning about these circumstances, Xiang Yuntian returned home and said to Bai Mengfei, "This Feng Biao is too suspicious. He is currently the prime suspect."

Bai Mengfei had an indescribable feeling; her heart felt heavy and she felt very uncomfortable, yet she couldn't quite put her finger on it.

Moreover, for some reason, she felt that Feng Biao might not be the real culprit hiding behind the scenes.

Just as she was about to take a shower, Bai Mengfei asked doubtfully, "Do you really think that Feng Biao would dare to do something like that again after just being released from labor camp?"

Xiang Yuntian did not respond immediately to this.

He lowered his head, frowned, and fell into deep thought.

After thinking for a while, he shook his head and said, "It's really hard to say. Forget it, let's not talk about this for now. Go take a shower first, let me think about it some more."

"it is good."

While Bai Mengfei was taking a bath, Xiang Yuntian promptly contacted Zhao Fei and asked him to arrest her.

After all, Feng Biao is the prime suspect, and he certainly has a motive for committing the crime.

Perhaps it was Lu You's girlfriend who provoked him?

These are all hard to say, and the truth is like a fog.

Just as Xiang Yuntian finished contacting Zhao Fei, Bai Mengfei hurriedly finished her shower and came out.
