Many people believe that serial killers are simply madmen or some kind of inhuman villain.
But this statement is actually not accurate. Serial killers will not print the words serial killer on their faces. Later research shows that there are some highly educated people in this group who have a sense of morality and are even willing to do whatever they want. The idealist where truth appears.
They are handsome, well-dressed, and talk elegantly. Some of them also have stable jobs and relationships. As for why they eventually become serial killers, there are various reasons.
The FBI defines a serial killer as one who has murdered at least three people and has a "cooling off" period during the crime, which is different from a mass killer who carries out massacres in the same place in a short period of time or a crazy killer who goes around killing people.
And Jack the Ripper is exactly a textbook serial killer.
The location of his crime was fixed in the Whitechapel area, and he had a consistent pattern of behavior. According to Lestrade's description, this occurred in three cases within half a month. The first case and the second case were separated by ten days. , while the interval between the second and third cases was shortened to five days.
It can be seen that his killing speed is obviously accelerating.
Whether they become serial killers out of mission, entertainment, ideals, or simply as a career, there is no doubt that they all derive a certain amount of satisfaction from killing people.
It's like someone addicted to games or big swords, except that serial killers are obsessed with killing people.
After each Great Sword, most people will have what is called the Sage Time, and the "cooling off period" is like the Sage Time for serial killers.
Serial killers will reach a peak of excitement through a murder experience, and then their emotions will gradually fall back. They will reminisce about their previous experiences, summarize their experiences, and continue to learn until the next time they commit a crime.
This is also where the trouble lies, because you are dealing with an opponent that is constantly evolving, and the shortening of the cool-down period also shows that the emotional stimulation that murder can bring to him is gradually waning, which is why he is Will need to commit crimes more frequently to be satisfied.
If Zhang Heng remembers correctly, two more murders occurred in the East District on the third day after the first letter. However, the method of committing the crime in one of them was different. Later researchers generally believed that that case was not Jack the Ripper himself. It's just unclear whether it was the work of an imitator or someone taking advantage of the chaos to kill people and then blame Jack the Ripper.
In short, there is not much time left for Zhang Heng. If possible, Zhang Heng does not want any more victims to appear, so the best result is to find the murderer within three days. Of course, considering that the murderer now commits the crime longer than in history. It has sped up a lot, and he may not have three days left, and besides that, he still needs to race with Holmes.
Zhang Heng did not waste time. After checking the body in the morgue, he immediately rushed to the scene of the crime. However, the place had been cleaned up after such a long time, and all the suspected evidence had been collected by the police. On the ground, there were There are still some residual blood stains, but other than that, there are not many clues that can be collected. However, after running through three places, it can be seen that the locations chosen by the murderer are becoming more and more bold.
From the initial dark alley, to the stocking area, to the fence behind the apartment, the possibility of discovery increases layer by layer.
Zhang Heng marked the three crime locations on the map, and then based on the address provided by the short police officer, he visited the first person who found the body and the last person who saw the victim. These people had obviously been reported by reporters. After being harassed for a long time by the police and various idle people seeking information, Zhang Heng became very impatient as soon as he said what he wanted to say.
However, when they saw the latter taking out the gold coins from his pocket, those people became hospitable again, repeating the words they had repeated countless times these days.
Zhang Heng had already seen this information from the police report, so it was not his focus.
Thanks to future generations of Ripper enthusiasts, Zhang Heng already has some lists of suspects in his hands. The specific names and ages may not be useful, but the corresponding occupations and motives for committing crimes are of great reference value.
For example, a retired police sergeant in later generations believed that Jack the Ripper was a sailor of a German merchant ship because Whitechapel was very close to the docks, and the time the merchant ship arrived and left London coincided with the time the victim was killed. , so he speculated that the murderer was probably a sailor. The reason why he mysteriously disappeared and did not commit another crime was because he took that ship to the United States.
Zhang Heng could ask about the sailor's question whether there were any sailors near the last person who saw the victim on the night of the incident.
In addition, there are theories like royal conspiracy, barber theory, midwife theory... This is the collective wisdom of everyone, and each theory has its corresponding entry point, but the effect is not very ideal after all, witnesses said There are a lot of things, but there is no unified enough caliber.
Zhang Heng realized that he might have gone astray. Of course, since he had such an advantage, he had to give it a try.
He had been so busy all the way that he didn't even bother to have lunch, and the sun was already going down in a blink of an eye, so Zhang Heng didn't continue. He had traveled a lot this day and got all kinds of information. It was time to stop. Sorted out my thoughts.
Zhang Heng returned to 221B Baker Street and saw that Holmes had finished dinner and was dealing with a plate of dessert.
He still looked unhurried. When he saw Zhang Heng coming back, he raised his head and asked, "How was your harvest today?"
"I don't have a clue yet, what about you?"
"I have found a very useful clue, and I am digging deeper along this clue. The results should be available tomorrow." Holmes smiled, "Do you need me to share some tips with you, my dear Eastern friend. "
Zhang Heng shook his head, "Those who run early may not necessarily reach the finish line first."
"That's true, but those who run early will always have an advantage. I'm already choosing which opera to watch." Holmes said, seeing Zhang Heng sitting opposite him.
Mrs. Hudson brought out the remaining dinner from the kitchen, which was bacon, peas, bread, and a few pieces of fruit. The dessert was pudding. Zhang Heng finished it quickly, wiped his mouth and returned From the bedroom, he took out the revolver he bought three months ago. In addition, there was a kerosene lamp and a knife.
Holmes raised his eyebrows, a little surprised, "You want to go back?"
Zhang Heng snorted, "That guy may commit crimes in the near future, and even if I don't meet him, I can still inspect the environment and conditions of the previous crime sites at night." After a pause, he added, "By the way, Also get to know the prostitutes as a group."
"Not bad," Holmes praised, "you have become more and more integrated into this city."
