"Do you think it's possible that Yang Zebiao was coerced into doing what he did?" Ran Tao guessed. "Although his name has the word 'Biao' in it, his personality doesn't match the meaning of the word. He doesn't look like a cold-blooded killer in any way!"
"Yang Zebiao is 1.72 meters tall and weighs 63 kilograms. He has no criminal record, no bad habits, and no fighting or shooting experience."
"If he was coerced, he would have been killed long ago!" Wu Xiumin denied. "It's impossible for him to appear again after 13 years!"
"Gao Facai …" At this time, Zhao Yu suddenly thought of something and asked Gao Facai, "I would like to ask you a question. If Wu Fangfang's murderer wanted to use Yang Zebiao's dandruff to forge evidence, would it be possible?"
"Before this, I was aware of this problem, so I specially tested it." Gao Facai took out his test report and said, "The residue was extracted from Wu Fangfang's left fingernail. The amount of residue in each finger was different. The middle finger and index finger had the most residue, followed by the ring finger, and the little finger and thumb."
"This condition is at least consistent with the scratches in reality!" Zhao Yu said. "There is not only skin tissue in the residue, but also a small amount of blood. It seems that Leader Wu scratched the murderer's skin with her fingers! But … "Gao Facai suddenly raised his head and said," Because we still have certain technical shortcomings in the residue detection, it is possible that someone deliberately framed Wu Fangfang! "
"Oh? Can it really be done? "Zhao Yu's eyes widened.
"Yes!" Gao Facai nodded. "The simplest way is to cut off Yang Zebiao's arm and bring it to the crime scene. After killing Wu Fangfang, the murderer can grab Wu Fangfang's fingers and scratch them hard. This way, it will be exactly the same as the real scene!"
"This …" Everyone stared at each other in confusion.
"Of course, there are more complicated ways," Gao Facai said seriously. "That is to extract enough skin tissue and blood from Yang Zebiao in advance, put them in a professional container, and bring them to the crime scene. After killing Wu Fangfang, the murderer can use some kind of sophisticated instrument to stuff the tissue into her fingernails!
"However, this requires a lot of technical skills and a lot of time!" Gao Facai nodded and said, "For a murderer who has just killed someone, it takes an extremely strong mental fortitude to do so!
"Of course, we can't rule out the possibility of multiple people committing this crime!" Gao added, "We have examined the scene carefully, but we did not find any footprints. This is enough to prove that the murderer is very good at anti-reconnaissance. At least, he is very familiar with the procedures and methods used by the police to investigate the scene!"
"Looks like …" Zhao Yu pondered. "The murderer isn't that simple. He might be a master!"
"I think so too!" Miao Ying said. "The murderer purposely used a blunt weapon like a hammer to mislead us into thinking that he killed people casually. This will divert our suspicion of the evidence under her fingernails … "
"So …" Zhao Yu thought for a moment, then asked, "Gao Facai, can I say that on the day Wu Fangfang was killed, Yang Zebiao was at least alive?"
"Um …" Gao Facai thought for a moment, then replied, "It's hard to say. As I just said, there are still flaws in the activity detection of the residue. We can't confirm whether Yang Zebiao was dead when Wu Fangfang grabbed him with her fingers or when someone else extracted his skin tissue!"
"Oh … Then … At least he hasn't been dead for a long time, right?" Zhao Yu asked.
"Leader Zhao, I understand what you mean!" Gao Facai was quite experienced, so he immediately explained to Zhao Yu, "Since this evidence has appeared, it is enough to show that Yang Zebiao hasn't been dead for a long time!
If Yang Zebiao died a long time ago, it would be impossible to extract his skin and blood at all! If he was frozen after his death, or if he had a living sample, then we would definitely be able to detect it!
Although there are flaws in our activity detection, at least it shows that Yang Zebiao's evidence is fresh enough! "
"Tsk tsk …" Ran Tao, who was behind Wu Xiumin, smacked his lips and whispered, "That's weird …"
"But, anyway …" Zhao Yu nodded. "Even if Wu Fangfang's murderer is not Yang Zebiao, it must have something to do with Yang Zebiao! So … If we catch the murderer, we may be able to solve the Ziliu case from 13 years ago! So, now … Zeng Ke, stay here, and the rest of you, follow me out of the crime scene! "
"Um … Wait …" Ran Tao asked in confusion, "Boss, didn't you just say that the focus of solving the case is the Ziliu case? Wu Fangfang's case … Um … "
"Zeng Ke …" Zhao Yu ignored Ran Tao and said to Zeng Ke, "Compare the outline of the suspect on the motorcycle to see if you can find anything."
"Okay!"
After Zeng Ke agreed, everyone got up together and prepared to leave.
"Silly …" Wu Xiumin pushed Ran Tao from behind, then said with a smile, "Did you eat too much during the New Year? The team leader's intention was to first sort out the case before investigating the case. Only then would they have a clear line of thought. Can't you see? Only by solving Wu Fangfang's murder case can we solve the Ziliu case? "
"Oh … That seems to be the case …" Ran Tao was still a little confused. "But … How do you explain the theft case?"
"Let's wait and see. If Liu Zhanbing and Xu Hai can't solve it …" Zhao Yu turned around and said, "We have to go there in person. Let's go …"
Just like that, following Zhao Yu's order, everyone went to Changming Martyrs Cemetery to investigate the crime scene.
When they arrived at the scene, it was just as Captain Wang Yongxia had said. Although the cemetery was close to the downtown area, it was extremely desolate. Moreover, because Wu Fangfang was killed on the fifth day of the first lunar month, the police couldn't find any witnesses near the crime scene.
The police could only see through the camera at the entrance of the cemetery that Wu Fangfang had arrived at the cemetery by taxi at about 8: 50 that morning.
After the crime, it wasn't until 11 o 'clock that an old cadre, who was visiting his comrade's grave, saw her and called the police.
It was said that if it hadn't happened to be seen by the old cadre, no one would have known when it would have been discovered!
Because of the timely discovery, the forensic doctor was able to accurately speculate that Wu Fangfang's exact time of death was around 9 o 'clock in the morning. In other words, she might have been murdered as soon as she arrived at her fiancé's grave!
