What a coincidence!

Bai Mengfei thought Zhao Fei's analysis made sense, so she turned to look at Xiang Yuntian and nodded gently.

Xiang Yuntian understood immediately and said to Zhao Fei on the other end of the phone, "Shall we go over and take a look?"

"Alright, the body has been taken back to the forensic center. Come and take a look. It's raining heavily outside, so drive carefully and don't rush." ​​Xiang Yuntian and Bai Mengfei had known Zhao Fei for so long, and this was the first time they had ever seen him so long-winded.

The two couldn't help but look at each other and smile.

After agreeing, Bai Mengfei and Xiang Yuntian hurriedly went out and rushed to the forensic identification center.

Corpses are naturally stored in cold storage.

After changing into her work clothes and putting on a mask, Bai Mengfei walked into the cold storage with Xiang Yuntian.

By this time, several forensic doctors, dressed in protective suits, had gathered around the body placed under the light.

Upon seeing Xiang Yuntian approach, the forensic doctors quickly made way for him.

One of the forensic doctors turned to look at Xiang Yuntian and said, "This body has already shown signs of rigor mortis, but livor mortis has not yet formed. Based on this, we can infer that the time of death should be within 24 hours."

After Bai Mengfei followed Xiang Yuntian closer, she turned around, slightly tiptoed, and softly asked Xiang Yuntian, "Could you ask them to leave first?"

Xiang Yuntian readily agreed and said to the forensic doctors present, "Gentlemen, could you please step outside for a moment? I would like to examine this body alone with my friend."

All the forensic doctors knew that Xiang Yuntian was exceptionally capable, so they all nodded in agreement.

After they left, Bai Mengfei stared intently at the corpse, then reached out to examine it. She first checked the deceased's jaw and neck, finding signs of downward pulling.

This indicates that the female victim had indeed passed away recently.

Next, she observed the deceased's pupils, gently pinched them, and waited for five minutes. She found that the pupils had not returned to their original shape. This is one way to determine whether a person is truly dead.

In the medical field, death is classified into three types.

Respiratory death, cardiac death, and brain death.

The first two cases still have a chance of being saved in a short period of time.

As for brain death, modern medicine recognizes it as true death, and once it occurs, there is no way to reverse it.

Then, Bai Mengfei gently pried open the female victim's mouth to examine the teeth inside, in order to estimate the victim's approximate age.

After confirming that the female victim was truly dead, Bai Mengfei officially began the investigation of the body: "The deceased was a woman, aged between 20 and 30, who died from violent injury, with the suspected cause of death being a blow to the cervical spine from a hard object..."

Xiang Yuntian watched quietly from the side, his opinion agreeing with Bai Mengfei's.

After the two finished examining the female corpse, Xiang Yuntian asked, "Is it necessary to go to the crime scene to investigate now?"

Bai Mengfei pondered for a moment, then turned to look at Xiang Yuntian, nodded firmly, and said, "It's necessary!"

“Mm,” Xiang Yuntian replied immediately.

Afterwards, the two requested to leave the forensic identification center and drove to the hotel room where the incident occurred.

The scene has been cordoned off by investigators, and everything except the body has been removed remains as it was.

As soon as Xiang Yuntian entered the room, he asked Bai Mengfei, "Do you think this is the primary crime scene?"

"Based on the time frame of the news report and the information Zhao Fei and his team obtained during their previous investigation here, this place is very likely the original crime scene."

Bai Mengfei lowered her head and pondered for a moment before saying, "Even if it isn't, the original scene should not be far from here. After all, the traces on the body match the condition of the room's floor."

After saying that, Bai Mengfei walked around the room to check.

As she walked, she carefully examined every corner, while also paying attention to the smells in the room.

There was no unusual odor in the room, nor was there any smell of smoke or cigarette butts.

After all, those who came to investigate before were all professionals and wouldn't smoke here. If someone left a cigarette butt here, they would have no way to explain themselves.

Although this is just a detail, it is precisely these details that forensic examiners pay attention to when investigating crime scenes.

At this moment, Xiang Yuntian was not idle either. He paid special attention to the corners of the room, the table, and the corridor outside.

He meticulously recorded the details of the scene, took photos and videos, and even took out silver nitrate solution and sprayed it on the table and cups.

Human sweat secretes sodium chloride and oil. If fingerprints are left, silver nitrate will react chemically with sodium chloride to produce silver chloride and sodium nitrate. After silver chloride decomposes when heated, sodium nitrate will leave a black fingerprint.

This is a commonly used method for forensic experts to extract fingerprints.

Bai Mengfei used to use a different method, using bronze powder or aluminum powder. If these materials were unavailable, toner could be used as a substitute. Then, she would gently brush the area to reveal the fingerprints. However, this method was not as convenient as the one Xiang Yuntian was using now.

The two began their own investigations and discovered that only one handprint had been found in the entire room. This meant that the murderer might not have even been at the scene.

That's quite strange.

After completing the survey, the two walked up to each other and looked into each other's eyes.

"What did you discover?" Xiang Yuntian asked.

Bai Mengfei gently shook her head and said, "Only a handprint was found. Apart from that, no bullet casings or anything like that were found in the room. It can be said that no other physical traces were left at the scene."

“The method of the crime is quite ingenious.” A glint of wisdom flashed in Xiang Yuntian’s eyes. “This shows that even if the murderer is not Fan Nianzhen, he deliberately disguised the murder as an accidental killing. This person is extremely meticulous.”

"Moreover, judging from the degree of rigor mortis, the body has been dead for no more than 8 hours. Rigor mortis usually begins to form within 1 to 3 hours, and at the latest 8 hours."

Bai Mengfei naturally agreed, recalling, "Her jaw and neck were still extending downwards, and there was urinary leakage from the body. Especially at the large joints, there was a clear downward trend, so I think the time of death must have been between 4 and 6 hours ago."

After listening, Xiang Yuntian nodded repeatedly.

Then, to help pinpoint the time, the analyst began, "That means she was murdered between 6:30 PM and 8:30 PM, which is right around dinner time. At that time, I had just dropped Zheng Xiuxiu off and hadn't been gone long."

"Yes, that means the murderer came to this room right after you left and killed the female victim."

After hearing this, Bai Mengfei lowered her head in deep thought, her face solemn, and she unconsciously crossed her arms over her chest, saying, "So, we can also go to the monitoring room to check which other suspicious people appeared during this time period, besides Fan Nianzhen, who can be ruled out."
