After everyone finished eating, they all walked towards the police station. Luo Tian held Luo Yang in his arms and walked at the front with Bai Chi. Zhan Zhao and Bai Yutang walked side-by-side behind them.
"Cat, what did you notice?" Bai Yutang was curious.
"Um..." Zhan Zhao thought for a moment then asked Bai Yutang, "Xiao Bai, do you think we should let Fang Wo take the polygraph, or not let him take a polygraph?"
"Didn't you said that we can't let him take the polygraph, but we can't not let him take one..." Bai Yutang looked at Zhan Zhao and said, "It's a dilemma."
Zhan Zhao nodded and smiled, "Then, for example, Fang Wo passed the polygraph, and the result of the trial is that he is not guilty...Then he will be released. At that time, if the Ripper case occurs again, what will happen?"
Bai Yutang was stunned. Then he nodded once he understood what Zhan Zhao meant, "I see. At that time, Lu Liang will be the target of public criticism, and his theory will also be made fun of!"
"Then...For example, if Fang Wo fails his polygraph and he is found guilty...Afterwards, another Ripper case occurs." Zhan Zhao continued to ask, "What will happen?"
Bai Yutang nodded, "When the time comes, the police will be the target of public criticism. We arrested the wrong person after working on the case for so long!"
"Finally." Zhan Zhao smiled, "If we let Fang Wo go first...The Ripper case is still open, and we catch Fang Wo again...But the Ripper case is still not closed...What will happen?"
Bai Yutang smiled and shook his head, "The public will think that the police and psychologists are idiots."
Zhan Zhao concluded, "No matter what we do, it will arouse public doubts about the participation of criminal psychology in criminal investigations."
Bai Yutang was suddenly shocked, "Cat, is that why there has been no open cases recently?"
Zhan Zhao smiled, "Fang Wo is just a process. Regardless of whether he is imprisoned or released, or even shot in the end...As long as the Ripper case continues, the murderer will achieve their final goal."
"That Lu Liang...He is being used as a gun." Bai Yutang frowned, "He's being used and yet he is still helping them."
"I think we should check Lu Liang's social relations and the people he often comes in contact with." Zhan Zhao said, "Also...In this world, everything happens for a reason, especially extreme things."
"So, you are saying that the purpose of the real killer is very clear, that he hates criminal psychology?" Bai Yutang said, "He looks down on the police, hates psychologists, and is familiar with medical science, or at least knows the structure of the human body..."
"There's a lot more..." Zhan Zhao suddenly said seriously, "Xiao Bai, I have actually been researching something recently."
"What is it?" Bai Yutang was curious, "There were no cases a while back, but you still looked very busy."
"I've been studying to humanize some behaviors!" Zhan Zhao said.
Bai Yutang said with admiration, "Then you should put your theory into human words. I am not that talented, and my scope of understanding is limited to humans."
"Piss off!" Zhan Zhao glared at Bai Yutang. He thought for a moment then said, "For example, a murderer kills a person, or harms a person...He will have motive for the crime, the location of the crime, the act of the crime, witnesses and so on. While the victim has social connections, reasons for being killed, and so on."
"En." Bai Yutang nodded, "That makes sense."
"The large number of serial killers, extreme felons and perpetrator that we come into contact with doesn't hate or detest just one or two people." Zhan Zhao said while walking, "They hate a group of people who have something in common. Or rather, what they hate is a type of behavior...Which their crime is based around...In our current case, the murderer is killing or harming people because of something he loath..."
"I understand now!" Bai Yutang laughed, "You are saying to think of this behavior or thing as a person. For example, the criminal this time hates criminal psychology. Which means criminal psychology is the victim. Then his social circle, characteristics, hunting places, people he might offend...Cat! Not bad!"
Zhan Zhao smiled, "Sometimes, things that are too scattered and can make people confused. But if we can combine the scattered things, we will have clues to look into!"
"In the past, we always looked for patterns from the victims, then looked for clues, before finally went on to arrest the killer." Bai Yutang understood what Zhan Zhao was saying, "What you studied was abstracting the vicitim and directly setting the possible area of where the murderer might be! This is a great way to deal with such a case which has no clues!"
Zhan Zhao reached out and patted Bai Yutang on the shoulder with satisfaction, "As expected of Captain Bai. You have amazing comprehension and analytical abilities!"
"Let's go back and list the possible areas where that murderer might be. There won't be too many people like him. We can keep an eye on them!" Bai Yutang excitedly pulled Zhan Zhao, "Let's go Cat! There's work to do!"
Bai Yutang and Zhan Zhao hurried back to the police station. That night, all the officers of SCI worked overtime, and all of them skimmed through a large number of materials. Zhan Zhao listed the following conditions for them:
1. Could have direct or indirect contact with Lu Liang, strongly agrees with his theory, and their remarks were provocative to a certain extent.
2. There was a certain degree of research in psychology. Similar articles had been published in the newspapers in the past. During the early stages, they were in support of psychology, while during the later stages, they were against it.
3. Had joined multiple psychological forums, and had often appeared in them at the beginning, but rarely in the later stages.
4, Had a chance to get close to a corpse.
5, Had some medical knowledge or some knowledge on the structure of the human body.
6, Young and strong, rarely spoke.
7. Their career was not successful, and economic condition was average. Their profession had a certain degree of freedom.
Five or more of the above conditions had to be met. After a long night of investigations, everyone identified three suspects. One was Lu Liang's student, Wang Le. He graduated and stayed in school last year. He had been Lu Liang's teaching assistant and had studied medicine. Another was Luo Xinyao, a netizen who often appeared on Lu Liang's personal forum. She was a trainee doctor and a fan of psychology, but her remarks were very radical. The last one was Zou Long, a teacher in the infirmary at Lu Liang's school. He usually got along well with Lu Liang and often had drinks together.
"These three satisfy the conditions." Zhan Zhao looked at Bai Yutang.
Bai Yutang sent Ma Han, Wang Chao, Zhang Long, Xu Qing, Zhao Hu and Luo Tian to monitor them by constantly swapping shifts around. The three people were monitored for a total of 24 hours a day for three days. Bai Yutang, Zhan Zhao and Bai Chi on the other hand continued to look for information in the police station.
After two days of tracking, the conclusion was that none of the three felt normal.
On the third day, Fang Wo's polygraph was taken live on television.
Zhan Zhao and Bai Yutang watched Fang Wo's polygraph process in front of the TV. In the end, Fang Wo successfully passed the polygraph test.
"This brat." Bai Yutang left threw away the remote control and shook his head, "He's not simple!"
Zhan Zhao was silent for a long time before he finally said, "Fang Wo is an expert. His identity is definitely not simple!"
"Cat, next will be the highlight. The results will be out in the afternoon!" Bai Yutang deployed large numbers of police personnel and made full preparations.
That afternoon, the result of Fang Wo's trial came out-- there was insufficient evidence and he was acquitted!
The result of Fang Wo's trial caused three waves. There was a lot of talk in the media, while the SCI office was empty. Everyone was out in the field, ready to go.
That night, the three suspects unexpectedly left the house at the same time. After meeting each other, they went to one place --Lu Liang's home.
When Bai Yutang rushed into Lu Liang's home, Lu Liang had been pressed down on the ground, and the scalpel in Luo Xinyao's hand had almost reached inside Lu Liang's stomach---the three suspects were arrested together!
It was just strange that Lu Liang had not made a sound even though his eyes were filled with pain. However, he was able to struggle and move.
Gong Sun suddenly saw a glass bottle next to him. It was filled with half a bottle of milk. He suddenly laughed and said, "So it's like this!"
"Gong Sun, what's going on?" Both Bai Yutang and Zhan Zhao were puzzled.
Gong Sun shook his head, "Have you ever heard of microwave burns?"
They looked at each other and nodded. Microwave burns were a common type of accident. The principle of microwave heating was to excite the molecules to produce heat, so when the liquid was heated in the microwave oven, the liquid would often be very hot, but the container would not be hot. Therefore, there were many careless parents who directly heated the milk with the microwave. When they took it out, they felt it was warm and fed it directly to their babies, resulting in serious burns.
People's throats are very fragile. Generally, about 50 degrees heat would produce burns, especially when force feeding. The place where food was swallowed happened to be where the vocal cords were. If too hot, it would cause disability! Lu Liang was probably poured with very hot milk, so although he was uncomfortable and in pain, he was unable to speak because of burnt vocal cords. So, he had no choice but to wait for his death.
Bai Yutang called an ambulance. Lu Liang held Zhan Zhao's hand tightly before he was taken to the hospital. Tears were in his eyes, and Zhan Zhao shook his head. It was estimated that this half-old man would have a psychological trauma for the rest of his life.
The three people were taken into custody. They got all three suspects. The open Ripper case was solved. Zhan Zhao was more careful as he asked Lu Fang to open a press conference. He spoke about the intentions of the murderer. He also said that Lu Liang had deliberately cooperated with the police and pretended to use Fang Wo's lie detection case to reveal the real culprit, and that there was a great unity within the psychologist circle.
In an instant, the public's opinions and complaints about criminal psychology disappeared. At the same time, Lu Liang, who lost his voice for a short time because of the burns, was labeled as a hero.
Lu Liang was surprisingly very low-key. He did not accept any interviews, nor did he want to see anyone.
A week later, Zhan Zhao received a letter that was sent to him by Lu Liang, with only four words on it-- benevolent man is invincible.
Zhan Zhao received the letter, but he was in a bad mood...Although the Ripper case had been solved, there were still no clues on the dismemberment case. In addition, Gong Sun gave everyone an frustrating piece of news. He had carefully examined the throat of the victim in the dismemberment case--there were no signs of burns.
The biggest headache was that the only person who knew anything, Fang Wo, was missing!
"Cat." Bai Yutang said helplessly, "It seems that the dismemberment case and the Ripper case are just a coincidence and are not related."
Zhan Zhao had been looking at the relevant information on these cases over the past few days. He found that the three killers were all on the same forum, which was a very small forum that could not be found on the search engine. The reason he was able to find the website was that the three of them had collections on their computers. This forum was called Phantom, which they visited almost every day.
It was an extreme psychological forum, and most of the topics discussed on there were related to abnormal psychology. Zhan Zhao could see from their remarks that the leader of the forum, named Phantom Lord of the Night, was a great instigator, and he had a lot of professional knowledge, as well as a deep understanding of psychology. He used a very skilful language to instigate chatters in the forum to commit crimes. In their posts, there were large numbers of bloody crime scenes written. It was unknown whether they were true or false.
However, when Jiang Ping looked through the website, she found that the server of this forum was overseas and could not be tracked for a while. Moreover, the forum stopped updating since the day the three people were arrested.
"Cat." After reading those printed posts, Bai Yutang said directly, "Why are there so many perverts in this world? The earth is too dangerous!"
Zhan Zhao said helplessly, "In general, pure theoretical science related to human behavior is very dangerous, just like psychology and religion. Once someone deviates from objectivity to extremes, they can become tools to instigate and control people, because in this world, people who have no weaknesses and no psychological problems almost do not exist. If they have weaknesses, they will definitely be taken advantage of."
"Ifeel that...This case is not over yet." Next to them, Bai Chi said suddenly,"I don't know what the ultimate goal is."
At that moment, the door of the office was pushed open. BaoZheng and Lu Fang walked in.
"Bao Sir?" Bai Yutang looked up and said, "CanI help you?"
BaoZheng nodded and said, "SCI has been established for a year now and hascracked many cases. Cracking open this case was even more beautiful. In orderto commend our police station for its contributions to the law and order in SCity, famous political and business figures in S City will hold a grand banquettonight. They want to thank us."
Bai Yutang and Zhan Zhao looked at each other. As soon asthey were about to refuse, they saw Bao Zheng glare at them, "There are alarge number of high-profiled participants, so everyone has to go!"
The two of them were powerless.
"It's at seven o'clock tonight, at the top floor ofthe International Hotel!" Bao Zheng scanned the everyone and said, "Everyoneat SCI need to dress nicely. If anyone dares to not go, then I will kick youout of the police force!" With that, he turned around and left.
Lu Fang smiled at everyone and whispered, "I knew thatit would be useless for me to talk. Bao Sir is indeed more overwhelming!"With that, he left with a smile.
After a moment of silence inside the SCI office, everyoneturned towards Bai Yutang and asked in unison, "Chief, what does he mean bydress nicely?"
Bai Yutang scratched his head and said, "Maybe wearwhat you usually wear when you go to a wedding."
Everyone was silent. As soon as they looked at theirwatches, it was almost time. Bai Yutang waved at them, "Go home and changeyour clothes!"
Zhan Zhao and Bai Yutang also reluctantly went home tochange their clothes.
"Xiao Bai, does the International Hotel belong to yourbrother?" Zhan Zhao asked.
"I think so...Its the venue of the Qi Lei shooting caselast time." Bai Yutang said with lingering fear, "There won't be anaccident tonight right? Your brother shouldn't rent this venue out in future anymore.He should open a funeral home instead."
"Don't talk nonsense. By the way, your brother isout." Zhan Zhao thought for a moment, "When did he come back?"
Bai Yutang shrugged, "I don't know. Ask Gong Sun. Ah..."
"What's wrong?" Zhan Zhao heard a sudden cryfrom Bai Yutang and leaned over to see.
"Cat, my eyelids are jumping!" Bai Yutang alsoleaned over and said, "Come here, give me a kiss!"
Zhan Zhao hit him!
