Chapter 93 The identity of the deceased must be confirmed
In the interrogation room of the Municipal Bureau, Xu Jiaguang sat in the detention chair, motionless, like a sculpture.
At this time, the lights outside were already on, but the entire city bureau was brightly lit. Because a major case had occurred, the entire city bureau was destined to have a sleepless night tonight.
Zhou Yi was treating his wounds in the infirmary when suddenly a fat man in a police uniform walked past the door and quickly came back.
"You are Zhou Yi, right?" asked the fat man.
Zhou Yi nodded. He had never seen this fat man before and didn't know who he was.
But I could vaguely guess who the other person was from his epaulettes.
Sure enough, the fat man said, "I'm Shi Tao, the captain of the second team. Old Wu should have mentioned me to you, right?"
Zhou Yi shook his head: "No, Captain Wu never said that."
Shi Tao suddenly felt a little embarrassed and immediately changed the subject: "I've heard Director Xie mention you several times."
Zhou Yi laughed in his heart, this time Director Xie was involved again.
"Captain Shi, is there something wrong?"
"I heard from them that the dismemberment case in Donghai Community was discovered only at your insistence?"
Zhou Yi did not answer because he didn't know what the other party was up to.
Suddenly, Shi Tao came up and said with a smile: "Zhou Yi, would you like to consider joining our second team? I have a lot more people here than Old Wu, and..."
Shi Tao lowered his voice and said, "I've been lacking a deputy captain here, the kind that has a regular position in the bureau."
Zhou Yi was somewhat surprised. He knew that Team 2 had more people. Due to the different division of responsibilities, Team 2 was responsible for anti-gangster work with a wider coverage.
But he didn't expect Shi Tao to offer such a lucrative condition. He had just been transferred from the grassroots to the Municipal Bureau for a week, and someone asked him if he wanted to be the deputy captain of the brigade. This was a bit magical.
Zhou Yi packed his clothes and said with a smile, "Thank you, Captain Shi, for your kindness, but I'm a timid person. Your anti-gang work is too hard and too dangerous. It's not suitable for me. I haven't even started a family yet, not even a girlfriend. The work of Team 3 is more suitable for me. I can solve cases by running around here and there. It doesn't require much technical skills."
Zhou Yi's words gave Shi Tao enough face. He praised the second team and belittled the third team, but also rejected him tactfully without offending anyone.
Shi Tao was very pleased to hear this and nodded repeatedly: "That makes sense, that makes sense. Old Wu's work is not difficult at all."
"Captain Shi, I'm going to interrogate the prisoner first."
"Okay, go ahead and do your thing."
Zhou Yi smiled and waved. Even after walking away, he heard Shi Tao say from behind: "If you need any help in the future, just let me know."
Zhou Yi turned around, clasped his fists, and said, "Thank you, Captain Shi."
Turning his head, Zhou Yi couldn't help but laugh at himself, thinking that he seemed to have become a little more smooth-talking.
After turning the corner, he ran into Wu Yongcheng. They had the same goal: the interrogation room where Xu Jiaguang was imprisoned.
"Is the wound okay?"
"It's okay, just two more stitches."
Wu Yongcheng looked down at the blood-stained collar of his shirt and said nothing.
"Has Xu Jiaguang spoken yet?" Zhou Yi asked. After being escorted back, Zhou Yi's wound was bleeding severely, so Wu Yongcheng asked him to treat the wound first while he interrogated him first.
"This guy hasn't said a word since he was put into the police car. Even after entering the interrogation room, he refused to answer any questions."
Zhou Yi's heart skipped a beat, and he hurriedly asked, "How's the autopsy going with the forensic doctor?"
As soon as he finished speaking, he saw Xu Nian in a white coat walking towards him, with a slightly tired look in his eyes.
"Xu Nian, what are the results of the autopsy? Can the identity of the body be confirmed?" Zhou Yi asked.
Xu Nian took off his mask and shook his head. "These body parts are already highly decomposed and heavily contaminated. An autopsy will be extremely difficult, and I'm afraid it will take some time."
Wu Yongcheng nodded and said, "Thank you for your hard work. It's been a long time since we've had such a big case."
Zhou Yi asked, "Can you confirm that the body part is Zhang Hui?"
This is the most critical issue.
But Xu Nian shook his head again, his face solemn. "The body parts are so decayed that we can no longer restore the deceased's original appearance. Not all ten fingers of the deceased have been found, and fingerprints cannot be restored. We are now trying to extract blood from the body, but it is also very difficult."
"Xiao Qiao is conducting an on-site investigation at Xu Jiaguang's home. That should be the first crime scene and also the dismemberment scene. Blood samples should be able to be extracted there." Wu Yongcheng said.
Xu Nian nodded, "But there's still one problem. We need Zhang Hui's blood type test results as a reference. Otherwise, even if we get a blood sample, we can't prove that the body part is Zhang Hui's."
Wu Yongcheng said, "I'll send someone to check right away. Zhang Hui has given birth twice, so the hospital should have her blood type results."
But Zhou Yi suddenly said, "Not enough."
"What?" Wu Yongcheng and Xu Nian were both stunned.
"I said blood type matching alone is not enough."
"Xu Jiaguang remained silent because he was certain we couldn't confirm these body parts were Zhang Hui's. As long as he denied it, Zhang Hui would remain missing, and these body parts would simply be nameless corpses."
Wu Yongcheng objected, "No, as long as Xiao Qiao detects blood at the crime scene and compares it with the blood type of the body parts, he will be unable to defend himself."
Wu Yongcheng's thinking was very normal. As long as a large amount of blood residue was found in Xu Jiaguang's home, it would prove that the body had been dismembered. Even if Xu Jiaguang still did not speak, the complete chain of evidence based on the established facts could be used to convict him and bring him to court.
This idea is correct, and Zhou Yi also agrees.
Xu Nian said, "The murderer must have done a lot of cleaning after dismembering the body, but you can try using luminol reagent."
The luminol that Xu Nian mentioned is a professional chemical detection agent. For blood that cannot be observed with the naked eye at the crime scene, the luminol reagent can reveal extremely small amounts of bloodstains.
It is widely used in criminal investigation scene investigation.
But unexpectedly, Zhou Yi shook his head: "Luminol should be of no use in this case."
"Why?" Both of them were surprised.
"When Sister Qiao and I first went to Xu Jiaguang's house, he was fixing the sewage pipe. The whole toilet was covered in traces of excrement splattering. I saw it with my own eyes."
"The huge drawback of the luminol reagent is that the light it emits when it reacts with feces is the same as the light it emits when it reacts with blood."
Hearing Zhou Yi's words, Wu Yongcheng immediately looked at Xu Nian, because he didn't know about this.
Xu Nian frowned slightly and nodded.
Wu Yongcheng looked at Zhou Yi in surprise. This kid knows all this?
"Not only excrement, but also animal blood and certain bleaching agents can cause luminol to develop."
"So luminol is just a means to an end. It's hard to use it as part of the chain of evidence."
Wu Yongcheng asked, "Could it be that Xu Jiaguang deliberately destroyed the sewage pipe because he knew this?"
Zhou Yi shook his head. "I don't think it's likely. It must have gotten clogged when he was flushing the body, and in a hurry he dismantled the sewage pipe to clear it, which caused a leak. It was probably a coincidence."
"Damn, is this guy lucky?"
Zhou Yi said, "Captain Wu, don't worry. There are other ways to confirm the identity of the body."
I went to visit the graves early in the morning, so I posted it late. I will post it five times in a row. I will post it right away.
