A forensic doctor is reborn, sir, please don't bully me!

Chapter 120 Ex-boyfriend

After the two men had gone far away, Xiang Yuntian took the test report and began to examine it intently.

Bai Mengfei offered him timely guidance: "Look at the details, pay attention to serum proteins, molecular cells, and see if there are any normal changes."

"Yes, I'm watching it now."

Xiang Yuntian paid even closer attention to the changes in the various data points on the report.

He then discovered that in a normal temperature and humidity indoor environment, all changes were within the normal range and there was nothing abnormal.

"Master..." Xiang Yuntian almost blurted out "Master", but immediately changed his mind.

“Zhang Ting, I didn’t find anything unusual here. I feel that apart from the body being disturbed, everything else is normal.”

"The body has been disturbed. What does that mean?" Bai Mengfei's gaze unconsciously darkened.

Xiang Yuntian held the report, thought it over carefully, and then slowly said, "This shows that the murderer may not have seen her face clearly when he killed her. In other words, the murderer may have killed the wrong person."

"Yes, that's a possibility."

"Who was the murderer originally intended to kill?"

Hearing Xiang Yuntian ask this, Bai Mengfei couldn't understand for a moment, shook her head inwardly, and said, "I'm afraid we still have to go to the scene again."

“But the scene has already been investigated, and no suspicious clues were found!” Xiang Yuntian said.

Bai Mengfei smiled slightly, already having made up her mind.

As the two passed a convenience store, Bai Mengfei went inside and bought a bottle of vinegar.

Why buy vinegar?

Because vinegar has an acidic pH, it can be used as an auxiliary test.

After the two returned to the scene, Bai Mengfei did not pour the vinegar directly onto the key locations at the crime scene, but instead sprinkled it on some surrounding areas.

The result was a surprising discovery.

The toilet was the real primary crime scene!

When the vinegar was poured on, the blood immediately underwent a chemical reaction, and the bathtub turned red.

"The deceased was killed in a relaxed state; we hadn't examined her hair carefully before."

As Bai Mengfei spoke, she turned to look at Xiang Yuntian.

"Indeed, the victim's hair was very likely pulled by the murderer."

Xiang Yuntian immediately understood: "Judging from the bloodstains, the deceased was probably taking a bath and then died in the bathtub. The murderer's method was quite swift and efficient."

After buying two boxes of instant noodles, the two hurriedly returned to the cold storage to continue their investigation of the body.

Because the body is frozen, the rate of change slows down.

The deceased's hair was covered with a layer of white frost, which would be difficult for an ordinary person to see, but Bai Mengfei could.

Wearing white gloves, she gently pried open the deceased's eyes.

"What are you looking at?" Xiang Yuntian asked.

"Of course, it's the cornea."

Bai Mengfei turned her head and glanced at him sideways before saying, "It's six o'clock now. If the time of death exceeds 24 hours, the cornea will become opaque because the white spots have already spread. She probably died around this time yesterday."

"Isn't our main focus on checking hair?"

Bai Mengfei gently touched the deceased's hair with tweezers and said, "It's very obvious that the hair has been touched."

After saying that, Bai Mengfei pinched the deceased's cheek, making the deceased's mouth open slightly.

"The biggest problem right now is that even with all this information, we still can't find the killer," Xiang Yuntian said with a hint of regret.

"As forensic doctors, our main responsibility is to conduct investigations and analyses of the dead, living people, physical evidence, documentary evidence, and crime scenes, without letting too much personal emotion interfere."

Upon hearing this, Bai Mengfei turned her head and reminded Xiang Yuntian, "Especially when facing a corpse, acting on emotions might affect your judgment of the body. You should examine the corpse carefully."

"Actually, we can tell without even looking that the deceased died around 6 a.m. yesterday. The spine suffered blunt force trauma, and it's not hard to tell from the marks that he died in the bathtub, not on the table," Xiang Yuntian analyzed. "The main thing is that the murderer was very cunning and deliberately disguised himself, that's all."

Bai Mengfei responded with an "Mm," and said, "That's true, but relying on these clues alone is no different from finding no clues at all, is it? How can we assist the police in solving the case with just these?"

Xiang Yuntian looked at the female corpse, shook his head, and said, "But this is all the clues she can give us."

“During the on-site investigation, we seem to have overlooked a very important detail,” Bai Mengfei said.

Xiang Yuntian stared at Bai Mengfei with a puzzled look, observing her expression, and asked, "Is there anything else I've overlooked?"

"window."

This made Xiang Yuntian realize something, but he didn't really want to go back to the scene anymore, so he said, "Actually, I don't think there's any need to investigate this case anymore. The murderer was able to cleverly cover up his criminal evidence."

Bai Mengfei's attitude was firm: "The net of Heaven is vast, and though its meshes are wide, nothing escapes it."

Under Bai Mengfei's unwavering gaze, Xiang Yuntian finally agreed to secretly accompany her back to the scene for further examination.

After arriving at the scene, the two conducted a thorough inspection together.

As a result, some soil was found near the window.

Bai Mengfei immediately used tweezers to extract the soil and put it into a plastic bag.

Just as Xiang Yuntian was about to speak to her, she was focused on the contents of the bag and only said one sentence: "Don't disturb me while I'm collecting evidence."

"Ok."

At the same time, Bai Mengfei also took photos of the window to preserve evidence.

After recording everything, as the two were leaving, Bai Mengfei said to Xiang Yuntian, "The case has progressed to this point, and we're temporarily at a standstill. However, if our reasoning is correct, the murderer will definitely return here to commit another crime and kill the person he truly wants to kill."

"But he's already made a mistake once, would he dare to try again?"

The two walked and talked along the corridor.

Just then, a man and a woman walked towards us, their tugging and pulling at each other attracting a lot of attention.

Bai Mengfei and Xiang Yuntian couldn't help but look up at the same time.

Among the men and women walking over, the woman turned out to be Zheng Xiuxiu.

The man, however, was not Jiang Fan.

Xiang Yuntian was curious about her coincidence of living on this floor, so he asked, "What a coincidence, you live here?"

Before Zheng Xiuxiu could answer, the man immediately asked, "Who is this person? Do you know him?"

Zheng Xiuxiu quickly explained, "He's just an ordinary friend."

After saying that, he grinned at Xiang Yuntian.

Xiang Yuntian didn't bother looking at her and turned to look at Bai Mengfei, whom he found pleasing to the eye.

Bai Mengfei suddenly felt that this case might really be related to Zheng Xiuxiu, so she asked with a smile, "Miss Zheng, does Jiang Fan know that you've done this?"

The man turned around in surprise and asked in a questioning tone, "And who is Jiang Fan?"

Zheng Xiuxiu immediately became hesitant and stammering.

Bai Mengfei answered for her: "Her boyfriend."

Unexpectedly, Zheng Xiuxiu argued, "He's my ex-boyfriend, and I've already broken up with him."
