crime profiler in the dark

One hour later, Sergeant Zhu from the Criminal Investigation Department of Baihu Police Station arrived at Weiyang Island by helicopter with his detectives and more than a dozen police officers from the support department. The police officers took pictures and surveyed the scene where Zhang Jie was killed. Sergeant Zhu and the others began to understand the case.

After listening to Yi Yunzhao's rough description of what happened, Sergeant Zhu was suspicious:

"If this murderer killed six people related to the nuclear pollution in City C by pretending to be an accident in four years, why did he suddenly use such a cruel method to kill innocent people?"

"So I'm personally inclined, the murderer is not the same person." Bai Haolin has already thought about this issue.

The previous murderers usually used invisible and highly technical killing methods, but Zhang Jie's corpse showed extreme cruelty and violence, and the criminal methods were quite different. Although some criminals would escalate their behavior during the crime process, they hardly jumped like this format change.

The iron bucket and rats were prepared by the murderer in advance. This kind of killing tool is very extreme. It was specially used for torture in the past. The reason why the murderer uses methods that will bring great fear and pain to the victim is because the victim’s despair will make him To his delight, it meant that the murderer had abusive tendencies, not at all the work of someone who killed six people and still remained silent.

In addition, in terms of the choice of victims, although the first six deceased were all high-ranking officials and dignitaries in City C, they were all related to nuclear pollution. The murderer killed Zhang Jie who had nothing to do with nuclear pollution at all, that is to say, they are very likely to have personal vendettas, or the murderer randomly found a victim in order to vent his resentment against the upper class.

Just why did he choose to kill Zhang Jie at this time?Was the killer demonstrating to the police, or did he have an impulse control disorder?

"Indeed, and I already know who the murderer is!" Yi Yunzhao said with great certainty.

"Who is the murderer?" Sergeant Zhu was a little surprised.

"Yesterday we met a dock worker from City C, Old Huang, at the yacht berth on Liuyang Street. He was very hostile to the officials from City C. He probably couldn't figure it out after he went back, so he killed him to vent his anger!" Yi Yunzhao's nostrils expanded, his expression angrily said, "I've asked Police Officer Liu to spy on him first."

It's not that Bai Haolin hasn't considered this possibility, but after analysis, he disagrees with Yi Yunzhao's opinion: in the conversation with them, although Lao Huang showed great indignation, he knew that the police were asking After who assassinated the relevant personnel related to nuclear pollution back then, the extremely unnatural and contrived cover-up showed that he had a pure mind, obvious likes and dislikes, and knew exactly what he should do when; he had been in City C for a long time, and he knew very well When the nuclear power plant was built, I naturally knew that Zhang Jie, who was only in his early 30s, had nothing to do with the matter, and there was no need to attack him; I learned from the conversation with Lao Huang that he had a family, a wife and children, and he also knew about the murder of six people. The murderer's method was secretive. Even if he wanted to imitate the murder, he would never use such a radical and brutal method that would expose him to the sight of the police.

"Very well, let's find out about the situation with him first," Sergeant Zhu said.

Although Bai Haolin doesn't think Lao Huang is the murderer, it is true that Zhang Jie was brutally murdered the night after chatting with him. It is very likely that he passed his negative emotions to the real murderer, so it is necessary to ask clearly Has he mentioned this to others.

As Yi Yunzhao said, Police Officer Liu has been monitoring Lao Huang's movements. Lao Huang will go to work at the yacht dock on Liuyang Street at ten o'clock every day, and today is no exception. At that time, he was cleaning a yacht. When he saw the police coming to find him, Lao Huang mocked:

"What's the matter? Police officer, if you say a few words, you're going to be jailed?"

"Old Huang, do you know Mr. Zhang Jie from Sanyang Street?" Officer Liu ignored him and asked first.

"C's new star in the political arena, I know him, but he doesn't know me." Although Lao Huang lives in Weiyang Island, he still cares about the affairs of his hometown. Zhang Jie has frequently appeared on TV recently, so Lao Huang naturally knows He, "What's wrong with him?" He looked puzzled.

"Where were you from eleven o'clock last night to two o'clock in the morning today?" This is the approximate time when Zhang Jie was killed.

"Sleep! What else can I do?" Lao Huang was even more confused, and he became alert, "Why are you asking me this all of a sudden?"

"Can anyone testify?" Sergeant Zhu ignored it and continued to ask.

"We are a group dormitory, and the other three people in our dormitory can testify!" Lao Huang was a little angry, "Why do you want to ask me this!!"

"We will verify what you said." When Sergeant Zhu said this, several police officers behind him had already gone to find Lao Huang's roommate, "Yesterday, after our police officer talked to you, did you talk to him? Who mentioned it?"

"A few friends and I play cards every night, and we said a few words during the game, what happened?" Lao Huang was a little anxious, "Is something wrong? Is Jiang Xingcheng dead?"

Because the police responded quickly, the news of Zhang Jie's murder was not leaked out. Everyone only knew that something happened to his house and was sealed off by the police, so Lao Huang didn't know that Zhang Jie was dead.

"It wasn't Jiang Xingcheng who died, but Zhang Jie." Sergeant Zhu stared closely at Lao Huang's expression.

Hearing this news, Lao Huang was shocked: "What?! Why, why Zhang Jie? How did he die? Are you suspicious of me? I didn't do anything!" As for stuttering due to anxiety.

"We need you to provide a list of all the people who know the content of your conversation with the police officer!" Years of criminal investigation experience told Sergeant Zhu that Lao Huang should not be the murderer.

"Okay, okay!" Lao Huang repeatedly nodded, "But they probably won't kill people! We're all just talking, who will really kill people?"

"Whether they killed anyone or not, we will investigate clearly." Sergeant Zhu said sharply, "But if you conceal anything, we will prosecute you as an accessory to the crime of murder!"

Lao Huang was horrified, and gave the police the list of all the people who were present when he complained about the nuclear pollution in City C yesterday. There were almost ten people. Worse, whether these people have told others is hard to say, not hard to imagine, the list of suspects will get longer and longer.
