Chapter 330: The Case is About to Be Solved
"Oh, okay. I'm afraid I don't have time for the time being." Xia Yu nodded.
"Not only that, there are two more tasks I need to trouble you with."
"Officer Zhou, please go ahead."
"First, go to Zheng Tianlan's house and talk to his wife to find out about the situation, including the relationship between them, the reason why Zheng Tianlan and his family of three moved out of the villa, and... find out about the relationship between Zheng Tianlan and Huang Yanli."
"Secondly, Zheng Guangming owns a large number of properties. We need to check the current living conditions of these properties to see if they are vacant or rented out."
Xia Yu asked, "Do you want to find out where Bai Xiuxiu lives?"
Zhou Yi nodded. Xia Yu was indeed a teachable young man. "Zheng Guangming has so many houses. If he wants to settle Bai Xiuxiu down, he'll definitely prioritize her living in one of his properties. Both deceased were wearing pajamas, so theoretically, the possibility of them staying in a hotel for a long time is low. However, we'll also need to conduct a basic investigation of the high-end hotels in Anyuan City."
Xia Yu nodded, but said with some embarrassment: "It's just this workload, I'm afraid it's difficult for me to complete it alone..."
"Call for help. You can ask Captain Pan to take the initiative and ask for personnel from the detachment to assist you and follow your command. You can also ask the police station for help. Remember, we are the Municipal Bureau, and we are handling a major case that the city leaders attach the most importance to. It has the highest priority."
When Xia Yu heard this, he was cheered up and immediately nodded to thank Officer Zhou for the reminder.
Seeing his back as he trotted away excitedly, Zhou Yi suddenly felt relieved. Young people still need opportunities to perform, otherwise their passion and spirit will easily be worn away, and they will become lifeless and no longer enthusiastic.
After making all these arrangements, Zhou Yi still didn't rush back to interrogate Zheng Tianlan.
Instead, he went to find Tang Wenli, because Zheng Guangming's current height matches that of the male corpse, but this alone is far from enough.
From a judicial perspective, faster and more decisive evidence is needed.
"Teacher Tang, is it possible to extract fingerprints from the male corpse?" Zhou Yi asked.
Tang Wenli shook her head without hesitation. "The success rate of extracting fingerprints from a body that's been decomposed for more than two weeks is very low. Because the surface layer of the skin swells and falls off during the decomposition process, the ridge structure of the fingerprints will be destroyed. So it's basically impossible."
Zhou Yi stroked his chin and thought, "Basically impossible... does it mean there's still a slight possibility?"
Tang Wenli smiled helplessly: "You are really persistent. Let me put it this way, in this situation, there are roughly three ways to extract fingerprints."
"The first method involves treating epidermal fragments. This involves softening the epidermis by soaking it in formalin or glycerin to restore it, and then using powder or tape for extraction. This is currently the most common method. Its advantage is that it's easy to perform, but its disadvantage is that the fingerprints extracted are completely affected by the degree of epidermal shedding."
Zhou Yi hurriedly asked, "Can this be done?"
"Yes, but the fingerprints extracted are likely to be small, localized fragments that cannot be used as reference evidence at the judicial level."
"What about the second one?"
"The second method is called dermal reconstruction. For epidermis that has shed but not yet severely decayed, the papillary structures of the dermis may still retain fingerprint traces. However, ordinary extraction techniques cannot be used to perform this. It requires more complex micro-dissection techniques, both equipment and people with experience in this area."
Tang Wenli was afraid Zhou Yi didn't understand, so she explained, "Simply put, most forensic doctors use systematic anatomy and regional anatomy in their daily work. They primarily study the human body's morphological structure through naked-eye observation. In our profession, this is collectively referred to as macroscopic anatomy."
"In contrast, microscopic anatomy is the study of the local morphological structure of the human body at a microscopic level through the use of a microscope."
Zhou Yi nodded: "Can I understand this as using a microscope to restore the rotten and detached finger skin?"
"Yeah, about the same."
"Then Mr. Tang, can you do this?"
Tang Wenli shook her head and said, "I only have some knowledge of this area. I'm not an expert. Besides, the equipment we have here doesn't support this. It requires an ultra-high-magnification optical microscope."
Zhou Yi lowered his head in thought for a moment, then raised his head and asked, "What about the third option?"
"I saw the third method in a professional academic journal, but I'm not sure if China has the technology to implement it yet. It uses laser scanning and spectral imaging to capture residual fingerprint traces. Theoretically, this has the highest success rate, but... in terms of practical application, I'm not sure if it's feasible in first-tier cities, let alone small places like ours."
"I understand." Zhou Yi nodded. Since the third option is not feasible at the current technical level, the best option is the second option.
It’s just that Tang Wenli can’t do it, but when he heard it before, he actually thought of someone who might be able to do this technology.
Xu Nian.
He remembered that in his previous life, he had heard Xu Nian mention that the topic of her graduation thesis was about the application of microscopic anatomy in clinical forensic medicine.
It seems that her university teacher is an authority in this field in China.
However, he doesn't know much about its specific practical applications.
"Teacher Tang, the second method, someone in Hongcheng might be able to do it. I'll make a call."
Tang Wenli was stunned and asked, "Can Song Yiming do this?"
Zhou Yi pulled out his mobile phone and said, "It's not Forensic Doctor Song, it's someone else."
Zhou Yi directly dialed the landline of the Forensic Department of Hongcheng City Bureau, and the call was connected after a while.
"Hello, this is the forensic department." Xu Nian's cold voice sounded on the other end of the phone.
"Xu Nian, I'm Zhou Yi, I'm in Anyuan now."
"An Yuan? No wonder I haven't seen you these past few days."
"I'm here to assist with the investigation. We have a very difficult case, and you might be the only one who can help us."
After a moment, Zhou Yi hung up the phone and said to Tang Wenli, "Teacher Tang, it's done. It's another female forensic doctor from Anyuan, Xu Nian. She's quite proficient in microscopic anatomy. She said she'll come to Anyuan early tomorrow morning with her equipment to assist us."
"That's great. Do you have such a high-power microscope in Hongcheng?"
"No..." Zhou Yi said, "but she said she has..."
Tang Wenli was stunned. "You have it at home? This kind of equipment is not cheap."
Zhou Yi sighed inwardly. If a professional forensic doctor said it was not cheap, then it really was not cheap.
The fact that Xu Nian has such equipment at home is probably related to her father.
After Zhou Yi was reborn, he had thought about the issue of Xu Nian's father.
The conclusion is that the three-foot-thick ice does not form overnight.
Her father's final result was that he was deported and returned to the country, which means that the country has thoroughly investigated your problems and must have committed major violations of regulations and disciplines and serious corruption.
When police investigate cases, even murder cases, there is always the possibility of false charges or wrongful convictions. However, when it comes to matters involving state officials, there is absolutely no room for error.
Therefore, he must not have made the mistake on a whim, but had been corrupted by power and money long ago.
It's just that there is no thunder yet.
Don’t say you don’t want to do anything. Even if you want to, you can’t do anything.
Remind someone to clean up their mess? Their first thought is to get rid of you because you might know something.
When the country investigates everything thoroughly, your future will be ruined just because you said this.
Therefore, the fate of some people has already been determined, and even if they are reborn, they cannot change anything.
That's why he thinks so clearly. If he hesitates in emotional matters, he will only suffer from the consequences.
Coming back to his senses from his sigh, Zhou Yi found himself walking out of the forensic room and standing in the corridor.
He picked up the phone and called Wu Yongcheng, firstly to report to him on the current progress of the case.
The second is to ask him to arrange someone to accompany Xu Nian to Anyuan tomorrow to ensure the safety of Xu Nian and the equipment.
He had a hunch that confirming Zheng Guangming's identity would be the key to finalizing the case.
On the phone, Wu Yongcheng told Zhou Yi to let Qiao Jiali accompany Xu Nian.
Zhou Yi heard the noise from the other side, which seemed to be on the road, so he asked, "Captain Wu, is there anything else going on?"
Wu Yongcheng said, "You're such a cunning fellow. I wanted to wait until I had the results before telling you. Biaozi, Chen Yan, and I will drive to Lujiang City."
"Lu Jiang? From another province?" Zhou Yi was stunned and asked hurriedly, "Did they find Fu Daqing?"
"It's still uncertain, but we can only say it's highly suspected. A suburban hospital in Lujiang admitted a patient who had alcohol poisoning from drinking fake liquor. The hospital felt the patient was suspicious, so they called the police. The patient has now been detained by local police, but he hasn't woken up yet."
"So they took a photo and sent it over. Judging from the facial features, he's very similar to Fu Daqing, but he's very unkempt and has a beard. So, to be on the safe side, we'll just go after him. If it's confirmed to be Fu Daqing, we'll interrogate him on the spot and bring him back."
When Zhou Yi heard this, he thought it was really good news. The case, which had been stalled for many days, had made significant progress today. It seemed that solving the case was just around the corner.
"Captain Wu, I'll wait for your news."
"Okay, I'll sync it to you as soon as I find out."
After hanging up the phone, Zhou Yi felt much more cheerful. This was probably the best day he had felt since coming to Anyuan.
After Pan Hongjie finished interrogating Jiang Wei, the murder of Li Youqiang should be clear. There was a witness at the car wash, and the homemade gun was physical evidence. It would be useless for Jiang Wei to resist.
When Wu Yongcheng arrived in Lujiang City and interrogated Fu Daqing, he was able to find out who hired the killer. What happened on March 16th and Li Youqiang's death could be matched with Jiang Wei's confession.
When Xu Nian arrives, if he can successfully extract the fingerprints of the male corpse, it will be possible to confirm for legal purposes that the deceased is Zheng Guangming.
By sorting out all of these, we can establish a complete chain of evidence.
Zhou Yi pushed open the door of the interrogation room, and Zheng Tianlan, who was sitting inside, had been tortured like a Shar-Pei dog.
Zhou Yi sneered and thought, it’s about time I take action against you!
