Many people thought that serial killers were pure lunatics or some kind of inhumane villain.
However, this statement was not accurate. Serial killers would not print the word serial killer on their faces. Later research showed that there was no lack of highly educated people in this group who had a strong sense of morality, and were even idealists who were willing to appear for the truth they were pursuing.
They were good-looking, well-dressed, and elegant. Some of them even had stable jobs and relationships. As for why they eventually became serial killers, there were a variety of reasons.
The FBI defined a serial killer as someone who had murdered at least three people and had a "cooling-off period" during the crime. It was different from a mass killer who carried out a massacre in the same place within a short period of time, or a crazy killer who went around killing people.
Jack the Ripper was a textbook example of a serial killer.
He committed his crimes in the Whitechapel area and had a consistent pattern of behavior. According to Lestrade's description, there were three murders that occurred within half a month. The first and second murders were separated by ten days, and the interval between the second and third murders was shortened to five days.
He could see that the speed at which he killed people was obviously increasing.
Whether it was out of mission, entertainment, ideals, or simply seeing it as a career to become a serial killer, there was no doubt that they could gain a certain sense of satisfaction from the activity of killing.
It was like a person who was addicted to games or playing with a sword. The only difference was that the serial killer was addicted to killing people.
After each killing, the average person would have a so-called sage period, and the "cooling-off period" was like the sage period of the serial killer.
Serial killers would use a murder experience to bring their excitement to a peak. After that, their emotions would gradually fall back, and they would reflect on the previous experience, summarize the experience, and continue to learn until the next crime.
This was also the troublesome part. Because you were dealing with an opponent that was constantly evolving, and the shortening of the cooling-off period showed that the emotional stimulation that murder could bring to him was gradually weakening. Because of this, he would need to commit more crimes to satisfy himself.
If Zhang Heng remembered correctly, three days after the first letter, there were two more murders in the East End. However, one of the murders was committed in a different manner. Later researchers generally believed that the murder was not committed by Jack the Ripper, but it was unclear whether it was the work of an imitator, or someone who took advantage of the chaos to frame Jack the Ripper.
In short, Zhang Heng did not have much time left. If possible, he did not want any more victims to appear. So, the best result was to find the murderer within three days. Of course, considering that the murderer's crime time was much faster than in history, he might not have three days left. Other than that, he still had to race against Sherlock Holmes.
Zhang Heng did not waste any time. After checking the body in the morgue, he immediately rushed to the crime scene. However, the place had been cleaned up a long time ago, and all suspected evidence had been collected by the police. There were still some bloodstains on the ground, but other than that, there of clues. Other than that, there were not many. Zhang Heng could tell from of the three places of the murderer of the murderer of of the three.
From the dark alley at first, to the warehouse area, and then to the fence behind the apartment, the possibility of being discovered increased.
Zhang Heng marked the three crime locations on the map. Then, according to the address provided by the short officer, he visited the first person who found the body and the last person who saw the victim. These people had obviously been harassed by the reporters, the police, and all kinds of people who wanted to inquire about information for a long time. As soon as Zhang Heng told them the purpose of his visit, he became impatient.
However, when they saw Zhang Heng taking out gold coins from his pocket, they became enthusiastic and hospitable again, repeating the same words they had repeated countless times over the past few days.
Zhang Heng had already seen this information from the report provided by the police, so it was not the focus of his attention.
Thanks to the Ripper fans, Zhang Heng already had a list of suspects in his hands. The specific names and ages might not be useful, but the corresponding occupations and motives of the crime were very useful for reference.
For example, a retired police captain in the future believed that Jack the Ripper was a sailor on a German merchant ship. Whitechapel was very close to the dock, and the merchant ship's arrival and departure time in London coincided with the time of the victim's death. So, he speculated that the murderer was likely a sailor. As for the mysterious disappearance of the murderer, he did not commit any more crimes because he boarded the ship and went to the United States.
Zhang Heng could ask the last person who saw the victim on the night of the crime if there were any sailors nearby.
In addition, there were similar theories like the royal conspiracy theory, the barber theory, the midwife theory … These were the wisdom of the masses, and each theory had a corresponding entry point. However, the results were not very ideal. Witnesses said all kinds of things, and there was not enough consensus.
Zhang Heng realized that he might have taken a wrong turn. Of course, since he had such an advantage, he had to give it a try.
He had been so busy that he did not even have time to eat lunch. In the blink of an eye, the sun was about to set, and Zhang Heng did not continue. He had been to a lot of places today, and the information he received was also varied. It was time to stop and sort out his thoughts.
When Zhang Heng returned to 221B Baker Street, he saw that Holmes had already finished his dinner and was eating a plate of dessert.
He was still unhurried, and when he saw Zhang Heng, he looked up and asked, "How's your harvest today?"
"I don't have any clues yet. What about you?"
"I have found a very useful clue, and I'm digging deeper into it. I should have results tomorrow." Holmes smiled. "Do you need me to share some hints with you, my dear friend from the East?"
Zhang Heng shook his head. "Those who run early don't necessarily reach the finish line first."
"That's true, but those who run early always have an advantage. I'm already choosing which opera to watch," Holmes said as he watched Zhang Heng sit across from him.
Mrs. Hudson brought out the rest of the dinner from the kitchen. It was bacon, peas, bread, and a few pieces of fruit. Dessert was pudding. Zhang Heng quickly finished it, wiped his mouth, and returned to his bedroom. He took out the revolver he bought three months ago, a kerosene lamp, and a knife.
Holmes raised his eyebrows, a little surprised. "You still want to go back?"
Zhang Heng nodded. "That guy might commit more crimes in the near future. Even if I don't meet him, I can still investigate the environment and situation at the previous crime sites," he added after a pause. "I can also learn more about prostitutes."
"Not bad," Holmes praised. "You are becoming more and more integrated into this city."
