Chapter 48 Using Crime to Judge Criminals

Xu Zhi looked at the two of them with a blank expression: "Wait, what did you find? I didn't see anything!"

Bai Xiao patiently explained, "There is another tiny wound inside Lu Yao's venomous fang wound. This wound was caused by an injection with a needle. It is not visible to ordinary people with glasses. You need a magnifying glass or a microscope to see it."

Xu Zhi finally realized: "Oh, I understand. So, after killing the person, the murderer covered the wound a second time to deliberately mislead our investigation and confuse us? So the real fatal wound wasn't snake venom."

“The fatal wound is still snake venom,” Bai Xiao said.

Xu Zhi stared wide-eyed at Bai Xiao, puzzled.

Qin Ruowei continued, "You can understand it this way: the murderer first sucked the snake venom into the needle, then injected the venom into the victim's body with a syringe, and then covered it up with the snake's fangs."

"So that's how it is!" Xu Zhi also understood. It was indeed difficult to carry a venomous snake to commit a crime, but it was much easier to carry a pair of snake fangs. However, a new question arose: "To inject accurately, the victim must first be unable to move. We did not find any other wounds on the victim."

Qin Ruowei continued, "You're right. A normal person would resist when facing a murderer. Even if she was tied up, there were signs of binding on her hands and feet. However, when I extracted the contents of Lu Yao's stomach and the gastric mucosa, I found a large amount of alcohol. In other words, the murderer injected snake venom into her while she was drunk."

"I see."

Upon hearing this, Xu Zhi couldn't help but gasp.

He couldn't help but admire the murderer's intelligence, and also Qin Ruowei's professional methods.

If what Qin Ruowei said is true, then everything makes sense logically.

"The only question now is, how did the killer evade the cameras?" Bai Xiao frowned.

Qin Ruowei skillfully pulled off her mask and gloves, washing her hands as she said, "This is your area of ​​expertise."

Every case is a tragedy, especially in a place like the autopsy room, where the discussion revolves almost entirely around the case, and no one mentions Lu Yao's personal behavior of abusing small animals.

This is a basic respect for the deceased.

...

After leaving the dissection room.

The afternoon sun was blindingly bright, and a scorching heat wave rose from the ground, making even the car doors hot to the touch.

The two got into the old Santana, and Bai Xiao turned the air conditioning up to the maximum.

As Xu Zhi fanned himself with his hand, he pulled open the collar of his uniform, sweat dripping down the back of his neck. He complained, "This damn weather is so hot. A few minutes' walk feels like it's taking half my life."

Bai Xiao handed him a tissue: "It's not the hottest time yet. Once July is over and the temperature reaches 40 degrees Celsius, you'll realize how unbearable this weather is!"

Xu Zhi wiped the sweat from his face with a tissue: "They always said Jiangcheng was hot, but I didn't believe it. Now I've seen it for myself. This feeling... is like being in a sauna."

Bai Xiao inserted the car key and said calmly, "Try to think positively. At least in this hot weather, most industries are in their off-season, and crime is no exception."

“That’s true.” Xu Zhi nodded in agreement.

While driving, Bai Xiao suddenly asked, "What do you think of Lu Yao and Zhao Qiangdong's case?"

Upon hearing Bai Xiao bring up work-related matters, Xu Zhi immediately became serious. After a moment of contemplation, he slowly said, "Although we currently know nothing about the murderer, based on the characteristics of the two cases, I have reason to suspect that the murderer is a person with a strong sense of individual heroism."

"Tell me about it." Bai Xiao glanced at him out of the corner of his eye.

Xu Zhi organized his thoughts and began to explain: "Lu Yao's case seemed like an accident, but as the case progressed, we discovered that behind her glamorous appearance lay a dark side, or even an extremely psychologically twisted pervert."

Bai Xiao didn't respond, but simply reduced the car's speed to fifty miles per hour.

Listen quietly.

Xu Zhi continued, "As for Zhao Qiangdong, as a major suspect in the Lu Yao case, I originally thought there was a high possibility that he was silenced, but when we visited his wife, we found that this guy was a domestic abuser."

"One is a domestic abuser, and the other is a pervert who tortures and kills animals. Both victims have one thing in common: they both have obvious moral stains."

"What the murderer did was more like a judge, settling accounts for their crimes in an extreme way."

"To judge criminals by crimes?" Bai Xiao muttered to himself.

Xu Zhi smiled and said, "These are just my speculations. I don't know much about criminal psychology. After all, you are the expert in this field, Master."

Bai Xiao gripped the steering wheel, his eyes focused on the road ahead. After a moment of silence, he spoke up: "Your analysis makes a lot of sense. These serial killers often have their own set of 'justice' principles. The killer's motives are likely stemming from personal injustices, which then lead to dissatisfaction with society, resulting in such extreme actions."

The law has loopholes.

They did something wrong, but couldn't be convicted.

Such cases are numerous.

The murderer punished the criminal in an extreme way, seemingly righteous, but his actions had crossed the line of the law.

Therefore, in the eyes of the police, he was also an out-and-out criminal!

“If this is the killer’s modus operandi, I think his next target won’t be far off.” Bai Xiao looked at Xu Zhi.

Xu Zhi frowned: "Then where should we start? We have too few clues at the moment, and we haven't even identified any suspects."

Bai Xiao pondered for a moment and said, "Let's go back to the station first and retrieve all the case reports that have caused a stir in society in the last three months, especially those cases involving moral depravity that cannot be filed. These may be the killer's next target."

"Understood, I will contact the internet monitoring department and ask them to assist in screening the relevant data."

Xu Zhi nodded in agreement.

......

Two o'clock in the afternoon.

The two returned to the station.

Bai Xiao picked up the phone and called Yuan Jianhua to tell him his thoughts. Yuan Jianhua took his views very seriously and immediately convened a meeting with the criminal investigation team, the internet surveillance department, and the forensic department to discuss them.

After more than two hours of discussion.

The meeting has ended.

Bai Xiao carried his water glass to the water dispenser, then took out a bottle of medicine from his pocket, opened it, poured out two pills into his palm, and then tilted his head back to swallow them in one gulp.

Xu Zhi walked over from behind and saw Bai Xiao taking medicine. He asked curiously, "Master, are you sick?"

"Vitamins, for boosting energy," Bai Xiao said casually.

"Give me two slices too!" Xu Zhi looked on longingly.

Bai Xiao glanced at him sideways and threw the bottle over: "Take them all. It's hot now, and it's easy to feel sleepy. It's good to keep them as spares."

"Thank you, Master." Xu Zhi smiled and opened the bottle, poured two pills into his mouth, swallowed them in one gulp, and immediately put on a pained expression: "This medicine tastes... weird?"

"Imported medicine, give it back if you don't want to take it." Bai Xiao's face was displeased.

"No, Master, there's no reason to take back something given to your disciple. It's a token of your appreciation." Xu Zhi said with a serious expression.

Bai Xiao ignored him and said indifferently, "I'm going to the archives. Let me know if there's anything."

"Don't worry, Master, I'm here," Xu Zhi said confidently.

Bai Xiao nodded and quickly walked towards the archives.

After Bai Xiao left, Xu Zhi returned to his post and quickly threw himself into his work.

Time passed by, second by second.

Before we knew it, it was evening.

As his colleagues packed up their things, someone came over, patted Xu Zhi on the shoulder, and said, "Xu Zhi, let's go out and get something to eat."

Xu Zhi looked up from a pile of documents, smiled and said, "I still have a few phone calls to make. You guys go ahead, don't worry about me."

My colleague laughed and said, "You're the most stubborn guy in the whole bureau. Okay, take your time with your work, and remember to eat."

After saying that, he left the office with his other colleagues.

The office gradually quieted down, leaving only Xu Zhi alone.

He was idly sorting through the surveillance footage, after all, this was no easy task, and he had always been the one handling it.

Just then, the glass door to the hall was gently pushed open.

A girl in a high school uniform walked in. She looked a little nervous, with her head down and her hands tightly gripping the straps of her backpack.

Xu Zhi looked up at her, somewhat surprised: "Classmate, who are you looking for?"

Lin Yueyue walked to the desk and said, "Officer, I have a very important clue to provide."
