In the following time, the detectives aired their opinions, sometimes arguing, retorting loudly, and sometimes standing up and pacing to organize their thoughts. Klein has been listening quietly without expressing any opinions.

When the exchange was coming to an end, he suddenly raised his hand and said, "I want information on serial murders that have not been solved in the last twenty years in Backlund, and even the entire kingdom."

The room was suddenly quiet for a few seconds, and most of the private detectives failed to understand Klein's intentions and thoughts.

Essinger put the pipe in front of his nose, took a breath, and said after deliberation: "Do you think the murderer is not a first-time offender?"

"You suspect that he has committed similar crimes before, even if the modus operandi was different?"

It's not doubt, it's almost certain... Klein replied in his heart.

Here is his reasoning based on the information provided by The Sun:

Since the murderer is "working hard" for Sequence 6 to be promoted to Sequence 5, then what did he do in the "serial killer" stage of Sequence 7?

If he hadn't committed a similar crime, it would be difficult for him to digest the potion. Even with the accumulation of time, there is a high probability of losing control from Sequence 7 to Sequence 6, and Extraordinary people in the "Abyss" pathway are high-risk patients in this regard .

Therefore, Klein judged that, regardless of whether the other party understands the "acting method", he should have completed serial murders for various reasons during the Sequence 7 stage.

In this way, it will not take a few years for the other party to digest the potion of Sequence 7. Even if Sequence 6 is added, the range of twenty years is a reasonable enough limit, because if you are too old, no matter whether the potion is digested or not, promotion is quite dangerous Yes, the whole person will become more and more crazy as the ceremony progresses, leaving obvious clues.

At this stage, the murderer is calm in committing crimes, has the ability to interfere with divination and tracking, and has almost no loopholes, but this may not be the case for him who was "young" in the early days!

When he completed the serial murder case for the first time, there was a high probability that he was not that cautious!

This is the best lead to follow!

Many thoughts flashed by, Klein nodded and responded, "That criminal's modus operandi doesn't look like a rookie."

"I have reason to believe he's done something like this before!"

"Combining the past and the present, we are more likely to grasp the key to the problem."

After hearing his answer, the detectives whispered to each other and began to discuss. After a brief silence, Essinger sincerely praised: "Great idea!"

In the evening, Klein sat on the easy chair in the living room, and under the warmth of the fireplace, he picked up the materials that Essinger's assistant had just delivered.

After his thoughts in the morning were praised by the big detective, Kaslana immediately expressed that she also needed a similar document, and Stuart sighed in a low voice, saying that he had faced Atruna from Klein before. He was calm and calm when he started the case. I believed that he was an excellent detective, but I didn't expect that he would be so good.

At the same time, he told Klein that if he needed help, he could go to him. He knew many friends in Backlund's detective circle.

Essinger Stanton also promised to contact the police department immediately and strive to provide the corresponding information to the necessary detectives before dark.

He really is very reputable.

At the next Tarot meeting, I have to ask the "World" to ask the little "Sun", the characteristics of the Sequence 6 "demon", and what abilities the Extraordinary of this Sequence possess... I didn't want to mix it up before, and I forgot to collect the corresponding information. Now that you have decided to help, you have to be prepared, so that you don�t know what�s going on in case of danger... Klein pondered for a few seconds, lowered his head, and looked through the entire Loen of the past twenty years under the light of the gas lamp. The Kingdom Unsolved Serial Murders.

And it was a lot less than he expected.

Four in Backlund, five in total in other cities, and only nine in total!

"Well, although the concept of DNA testing has not yet appeared in this world, and it lacks many necessary criminal investigation techniques, under the impetus of the emperor, there has been a relatively well-formed 'fingerprinting', and there are also psychic, divination, dreaming Wait for extraordinary means! When a single murder case does not involve nobles, rich people, or officials, the police department will often not turn to the extraordinary teams of the three major churches. However, the impact of serial killings is very bad and it is easy to cause panic. They will definitely do it Make the most sensible choice... In this way, it is reasonable and logical that there are only a few unsolved serial murders within 20 years." Klein quickly figured out the reason.

He restrained his thoughts and flipped through the cases one by one.

In the absence of enough information to make a divination, he initially selected two serial murder cases that might be related to the current incident, intending to use this as a preliminary entry point.

One case happened four years ago. There were five victims, all single prostitutes with one child. They were abused before their death, but they lacked any signs of having sex with others. JrNovels.com
