Chapter 483 Analysis

"Hmm? How did you figure that out?"

Zhao Fei asked, his face full of surprise.

Bai Mengfei silently walked forward, slowly squatted down, and stared intently at the dark-colored floor, carefully observing every detail.

"This place has obviously been cleaned, which is why it's so clean. However, I suspect that the person who cleaned it was not the deceased, but the murderer."

Upon hearing Bai Mengfei's deduction, Wang Tian immediately stood up and said with a face full of doubt, "How did you come to this conclusion? Could it be just based on intuition?"

“Of course not.” Bai Mengfei’s eyes remained fixed on the floor as she calmly said, “Actually, it’s not difficult to figure this out. Just give me a UV pen, and I can prove to you that there was blood here.”

"Is it really that amazing?" Wang Tian asked in surprise, her face full of doubt.

Bai Mengfei nodded gently and answered affirmatively, "That's right."

However, Wang Tian remained somewhat skeptical and frowned. She pondered for a moment, then said, "Let's consider this the primary crime scene. Let's begin our investigation now." She then muttered to herself, adding softly, "Actually, I think it's a bit too hasty to conclude that this is the primary crime scene so easily."

Bai Mengfei heard Wang Tian's mutterings but pretended not to. Her judgment was based on rigorous logical reasoning, not on unfounded accusations.

Zhao Fei agreed with Bai Mengfei's idea and immediately instructed the accompanying criminal police officers: "Everyone, pay close attention to every corner here, and try not to miss any details. Do you all understand?"

"Understood!" the team members answered in unison.

Zhao Fei grunted in agreement and then joined the others in examining the scene.

Bai Mengfei joined in, searching for evidence with everyone. But just as she had predicted, the scene had already been carefully cleaned by the murderer.

In fact, besides the bloodstains on the living room floor, there were also bloodstains in the kitchen, bathroom, and other places.

Bai Mengfei closed her eyes slightly, and the scene from that time involuntarily surfaced in her mind.

The murderer may be holding a sharp blade, slowly approaching the victim.

The victim, still alive, struggled to crawl to this spot. The murderer then stabbed the victim repeatedly with a knife, initially hitting areas that were clearly not vital. The victim then likely struggled to crawl into the living room, where the murderer finally stabbed him to death.

After the victim's death, the murderer began to destroy evidence, attempting to cover up the body, leaving red bloodstains in the toilet. Moreover, the murderer's actions were likely hasty, and they didn't realize that water couldn't completely wash away the bloodstains.

Thinking of this, Bai Mengfei slowly opened her eyes.

Just then, Zhao Fei walked over with a photo in his hand and said to Bai Mengfei, "I've found an important clue!"

"What is this?" Bai Mengfei glanced at it curiously and found that the photo showed a man and a woman. The woman was the deceased Cai'er, and the man, judging from his appearance, was probably her boyfriend or brother.

Bai Mengfei couldn't help but ask, "Does Cai'er have an older brother?"

Zhao Fei shook his head slightly and said, "No. That's precisely why it seems suspicious. She works in that kind of industry; I never expected her to have a friend like this."

Bai Mengfei found it strange, frowned, and asked Zhao Fei, "Where did you find this photo?"

Zhao Fei turned his head and looked at the coffee table next to him, saying, "It was found under the glass on the coffee table."

“This photo should be taken back and analyzed to see what’s on it…” As she spoke, Bai Mengfei took out an ultraviolet flashlight and shone the photo with strong light.

No fingerprints were found in the photo.

Since Zhao Fei is a criminal investigation expert, he would naturally wear white gloves when handling these items, so as not to leave fingerprints on the photos.

Just as Bai Mengfei was pondering this, Zhao Fei said, "Perhaps our criminal police can start their investigation by focusing on this man."

Bai Mengfei slightly raised the corners of her mouth, revealing a forced smile, and then said, "It's possible. However, I think the man in the photo is innocent."

"Why do you think that?" Zhao Fei asked curiously.

Bai Mengfei looked towards the coffee table and said in a deep voice, "Don't you think the photo is too conspicuous? The murderer cleaned almost the entire room; how could they possibly leave such a photo there?"

Zhao Fei pondered for a moment, then slowly nodded and said, "That makes sense. So the murderer left this photo likely to confuse our police investigation. However, for now, this photo is our only useful clue, so we can only investigate in this direction for the time being."

Bai Mengfei nodded slightly, then walked into the restroom. She knew the murderer must have been in that restroom.

She inadvertently found a cigarette butt in the toilet bowl.

The deceased woman, Cai'er, probably didn't smoke, right?

Out of curiosity, she turned to Zhao Fei and asked, "Captain Zhao, Cai'er doesn't smoke, does she?"

Zhao Fei said, "You're a forensic doctor, you should know this better than I do, right? Doesn't the autopsy report say that she had a stab wound to her lung, but her lung function was originally normal?"

"Oh, right!" Bai Mengfei nodded, then prepared to pick up the cigarette butt. "So, this cigarette butt is very likely left by the murderer."

After saying that, she stopped what she was doing and said to Zhao Fei, "Captain Zhao, could you please come over here for a moment and have someone come and retrieve this piece of evidence?"

Upon hearing Bai Mengfei's words, Zhao Fei curiously went into the restroom and took a look. Finding the cigarette butt, he had no choice but to call his subordinates to retrieve it.

After the subordinate came in, he successfully retrieved the cigarette butt.

"I never expected to find a cigarette butt like this here," Zhao Fei said.

Bai Mengfei smiled calmly and then said, "That's normal. It shows that the murderer is probably a heavy smoker."

"No, I just find it strange. Isn't he usually quite meticulous? He even cleaned the whole room, so how come he didn't notice that there was a cigarette butt left in the toilet bowl?"

Just as Zhao Fei was feeling puzzled, Bai Mengfei explained, "Because the filter in the cigarette butt is made of sponge. The murderer must have used the toilet here, smoking while defecating. After finishing, he threw the cigarette butt into the toilet bowl, hoping the water would wash it away, but he overlooked the difference in density between sponge and water, which is why the cigarette butt remained."

After hearing this explanation, Zhao Fei nodded as if he understood, and said with a look of understanding, "I understand."
