v2 Chapter 260： Cooling period

Many people think that serial killers are pure lunatics or some kind of inhuman villains.

But this statement is actually not accurate. Serial killers do not print the words of serial killers on their faces. Studies in later generations have shown that there are many high-educated people in this group, who have a sense of morality and are even willing to pursue what they seek. The idealist who the truth appears.

They are handsome, well-dressed, and elegant. Some of them also have stable work and relationships. There are various reasons why they will eventually become serial killers.

The fbi's definition of serial killers is that they have murdered at least three people, and there is a "cool-down period" during the crime, which is different from a mass killer who launched a massacre at the same place within a short period of time or a crazy killer who murdered people everywhere.

And Jack the Ripper is just a textbook serial killer.

The location of his crime was fixed in the Whitechapel area, with a consistent pattern of behavior. According to Lestrade, this happened in three cases within half a month. The first and second cases were separated by ten days. And the interval between the second and third cases was shortened to five days.

It can be seen that the rate of his killings is clearly accelerating.

Whether it is out of mission, entertainment, ideal belief or simply consider it a career and become a serial killer, there is no doubt that they can gain a certain satisfaction from the killing activity.

It's like someone who is addicted to games or big swords, but serial killers are addicted to killing.

After each great sword, most people will have the so-called sage time, and the "cool-down period" is like the sage time of the serial killer.

The serial killers will make their excitement reach a peak through a murder experience, after which their emotions will gradually fall back, reflect on previous experiences, summarize experiences, and continue to learn until the next crime.

This is also troublesome, because you are facing an opponent that is constantly evolving, and you can see from the shortening of the cooling-off period that the emotional stimulus that murder can bring to him is gradually declining. More frequent crimes will be required to be met.

If Zhang Heng is not mistaken, on the third day after the first letter, two more murders occurred in the Eastern District, but one of them committed a different crime. Later researchers generally think that the case was not Jack the Ripper. What I did was just unclear whether it was a masterpiece of the imitator or someone was touching the fish in the muddy waters and blame him on Jack the Ripper after the murder.

In short, Zhang Heng does not have too much time. 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 ’s crime time is now longer than in history. It has speeded up a lot, and he may not have three days left. In addition, he needs to race against Holmes.

Zhang Heng didn't delay. After checking the corpse in the morgue, he immediately rushed to the scene of the crime scene, but there has been cleaned up so long after the incident happened. The suspected evidence was collected by the police. There are still some remaining blood stains, but there are not many clues that can be collected, but you can see through three places, and the location chosen by the killer is becoming more and more bold.

From the original dark alleys, to the cargo area, to the fence behind the apartment, the possibility of being discovered is increasing layer by layer.

Zhang Heng marked the three places of crime on the map, and then he visited the first person to find the body and the last person to see the victim according to the address provided by the short police officer. These people were obviously also reported by reporters. He was harassed for a long time with the police and various probing news, and Zhang Henggang became impatient when he said something.

However, those who saw the latter withdrawing gold coins from their pockets became hospitable again, tirelessly repeating how many times these days have been repeated.

Zhang Heng has already seen this information from the report provided by the police, so this is not the focus of his attention.

Entrusting the blessings of the Ripper enthusiasts, Zhang Heng already has a list of suspects in his hands. The specific names and ages may not be useful, but the corresponding occupations and crime motives are of great reference value.

For example, a later retired sheriff thinks Jack the Ripper is a seaman of a German merchant ship, because the Whitechapel area is very close to the dock, and each time the merchant ship arrives and leaves London, it matches the time of the victim's killing. So he speculated that the murderer was probably a seafarer, but after the mysterious disappearance, he did not commit another crime because he took the ship and went to the United States.

And Zhang Heng could ask the seafarer if there was any sailor near the person who saw the victim last night.

In addition, there are similar to the Royal Conspiracy Theory, Barber Theory, Midwife Theory ... This belongs to the wisdom of the crowd, each theory has a corresponding entry point, but the effect is not very satisfactory after a lap, witnesses said There is everything, and it has not formed a uniform caliber.

Zhang Heng realized that he might have gone the wrong way. Of course, since there is such an advantage in hand ~ www.novelhall.com ~ it is always a try.

All the way to the present, I have not been able to eat lunch, and in the blink of an eye, the sun is about to go down, Zhang Heng has not continued, he has run a lot of places this day, the information is also varied, it is time to stop Organize your 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 awkward. When Zhang Heng came back, he looked up and said, "What's your harvest today?"

"No clue yet, how about you?"

"I've found a useful clue, and I'm digging along this clue. It should be fruitful tomorrow." Holmes laughed. "May I share some hints for you, my dear Oriental friend. "

Zhang Heng shook his head. "Early runners don't necessarily reach the end first."

"That's a good thing, but people who run early will always have an advantage. I'm already picking which opera to watch at the time." Holmes said, watching Zhang Heng sit opposite him.

Mrs. Hudson brought out the rest of the dinner in the kitchen. It was bacon, peas and bread, and a few petals of fruit, and the dessert was pudding. Zhang Heng finished quickly and returned with a swipe of his mouth. In the bedroom, I took out the revolver I bought three months ago. In addition, there was a kerosene lamp and a knife.

Sherlock Holmes raised his eyebrows, with a little surprise, "Would you like to go back?"

Zhang Heng yelled, "That guy may commit a crime in the near future, and even if he can't meet him, I can take a look at the environment and situation of the previous crime sites at night," he added, "By the way Also get to know the witches group. "

"Good," Holmes praised. "You have become more and more integrated into this city."
