Mystery Hunter

"I won't let you go." This is the last sentence left by the woman at the end of the video.

This inexplicable video ends here, and it's unclear what the crime consultant's true intentions are. But since this criminal consultant came to the door on his own initiative, and used a bomb as a "meeting gift", one can imagine his aggressiveness. It's just that he doesn't know exactly what he's going to do.

Guan Deng freezes the last picture so that he can see the woman's face clearly. It's just that the woman's hair is disheveled, and her hair covers most of her face, making it difficult to recognize. Gwanden needs to compare the blurry image to a criminal with a previous conviction or a missing person to determine the woman's identity.

Old Shao thought back and said, "Do you know why our task force was established?"

Xu Yiman said: "You told us before that you want to track down a person named Wei Demian."

Shao Lao nodded: "Yes, on the black business card, the words 'criminal consultant' came from this person. I met this person when I was 30 years old. This person is a proficient in hypnotism. The hypnotist. Always hypnotize you in unexpected situations, and in a very short time, it will make you fall into a hypnotic state without knowing it.”

"He was dangerous at the time, even though he didn't commit a crime directly. But everyone who met him, no matter how long it took, would always turn out to be a criminal later on. That's why he was actually imprisoned in a mental hospital. , was closely guarded. Everyone knew how terrible he was, so the mental hospital stipulated that no one should have a word with him."

Mr. Shao recalled what happened when he was young: "But at that time, I met a very smart man, he was a natural criminal policeman. It was just in a large-scale pursuit operation, that man died. However, the criminal crossed Chencang on the Mingxiu plank road and rescued Wei Demian."

"Wei Demian, who escaped from the mental hospital, lost his whereabouts for a while. Until 30 years passed, I thought he was dead. Now he is in his 18th year, almost 90 years old. I'm also 60 years old this year. It's the age to retire. And I also wrote some of my life experiences into my publication "Criminal Minds Research", and I have fulfilled my duty."

"Do you know why I stayed?" Mr. Shao changed his words and said to everyone, "Because when I was going to France to find my old colleague, someone put a black business card in my pocket. I know it was Wei Demian came back, so I stayed, our feud started decades ago."

Jiang He pointed out the loophole in Shao Lao's words: "Shao Lao, you said that Wei Demian is almost ninety years old this year, which means that he has no energy and ability to do anything, even if he is a very good hypnotist. I think , he must have some help."

Shao Lao nodded heavily: "It's exactly the same as what I thought. Twenty years ago, my apprentice and I both died in that operation. I can select excellent talents from within the police, but I hide and hide. Wei Demian can't do it. I suspect that in the 20 years since he disappeared, a new apprentice has been cultivated."

After speaking, Shao Lao waved his hand: "Let's not talk about these old grudges, let's start with the details. We have played against this criminal consultant before, and it was he who led us into the deserted village. Think about it carefully, What are the characteristics of this crime consultant when he commits crimes."

"He won't take the initiative to kill." Xu Yiman wiped the tweezers on his hands with alcohol, because there were so many thorns on Jiang He's back, Xu Yiman's white gloves were covered in blood: "Criminal consultant, as the name suggests, is to help others who sin."

"That's right." Mr. Shao agreed very much: "The murderers we caught before were all used by this criminal consultant, either because of money, or because of other relationships."

"This involves another feature." Shao Lao looked around: "The person killed by this criminal consultant was a person who had a previous criminal record or did something bad, but was lucky enough to escape legal punishment."

Yuan Jun scratched his head and said, "Is it like a human trafficker like Niu Qiuju? Although she hasn't abducted and sold children for many years, the criminal consultant still hasn't spared her."

"Treat others in the same way." Hearing Yuan Jun's words, Xu Yiman thought again: "This criminal consultant always treats the people he chooses in the same way. The big boss who touched porcelain before. ~Master, it was designed to kill his own son. And that liar was tricked into committing suicide by the criminal consultant. Niu Qiuju kidnapped and sold other people's children, and the criminal consultant kidnapped and sold Niu Qiuju's grandson."

"That's right." Several people nodded.

"Those are the three characteristics of a murderer. First, he planned this thing behind the scenes and didn't personally participate in the killing. Second, he was selective in choosing his targets. Third, he would harm in the same way that his target had done. The other party." Mr. Shao concluded: "This is the characteristic of a criminal consultant. If you follow these three points to investigate, you will definitely be able to find out some clues."

"What do you think of Jiang He?" Elder Shao turned to look at Jiang He.

During the discussion just now, Jiang He didn't say a word, as if he wasn't interested in this matter. Old Shao knew that Jiang He had always been observant, with first-class vision, hearing, and even smell. In addition, he suffered from hyperamnesia. As long as he experienced it, he would not forget any details.

Elder Shao wanted to hear Jiang He's conclusion, but found that Jiang He's eyes were fixed on the computer screen.

Jiang He didn't seem to hear Old Shao's words. He suddenly got up and knocked over the plate with the blood-stained gauze on the side.

"What are you doing?" Xu Yiman scolded.

Jiang He said to Guan Deng, "Replay the video for half a minute."

Guan Deng heard the words, nodded, and adjusted the video back.

Everyone was staring at the computer screen at the moment, wanting to see what Jiang He had seen from the video. The video is still pitch black, and the woman has not yet appeared in the camera. The camera swayed through the window in the room, and the sunlight entered the room, which made the room brighter.

At this time, the woman appeared in the video.

In just 30 seconds, it really couldn't hold any useful information, and there was no important clue at all.

"Don't move." Xu Yiman patted Jiang He on the shoulder and said, "The thorns on your back haven't come out yet, don't move."

Jiang He suddenly turned his head and said to Xu Yiman, "Have you seen the morning sun?"

"Why do you ask this all of a sudden?" Xu Yiman really couldn't keep up with Jiang He's jumping logic.

"Because we can distinguish a lot of things through sunlight." Jiang He pointed at the video screen and said, "There was a setting sun just now~ Didn't it come in?"

Xu Yiman nodded: "Indeed."

Jiang He opened his mouth and said, "If you often watch the sunrise and sunset, then you can easily distinguish whether the incoming sunlight is the incoming sunlight in the early morning or the incoming sunlight in the evening. From this oblique light, , the sun is slightly orange, which is more heavy than the early morning sun."

"Can you tell the heavy feeling?" Xu Yiman shook his head and asked.

Jiang He nodded: "I have studied sunlight before, and every photographer who is sensitive to light can do this. Show them this video and they should be able to get an accurate answer. To illustrate the problem, it is now between the summer solstice and the autumn equinox, and due to the altitude of the sun and the point of direct sunlight, the sun at our coordinate latitude rises from the northeast and sets from the northwest."

"That is to say, the sunlight comes in from the northwest." Jiang He continued: "Because the north of the Tropic of Cancer will never be directly exposed to the sun, the sun at noon will always be in the south, so most buildings in the north are It is facing south. At least the lighting surface should be south, such as bedroom, living room and so on.”

"And the sun in the evening has almost fallen below the horizon, blocked by various tall buildings, but this is not the case in this video. From all the above information, we can easily draw a conclusion." Jiang He climbed again down so that Xu Yiman could clean up his wounds again.

"What conclusion?" Xu Yiman asked curiously.

"The place where the woman was imprisoned was a cellar, and the small window of the cellar was open to the north. Only when the sun rose and set, a ray of sunlight could come in~ and most of the time, the cellar was in the shade and the sun was shining. No. It's just that I can't think of why the killer would do this."

"There aren't any tall buildings around this cellar, otherwise those buildings would block the last sunlight and leave shadows in this room. But there are none in the video, which means the cellar is in the open. The woman in the video is crying constantly, but But no one came to check the situation. Besides, although the small window would not let people escape, it was very easy to transmit information, but the murderer did not seal the window."

"So I have a 60% certainty that the woman's cellar must be located in a suburban, sparsely populated place. The east and south are close to the river, but there is no sound of water in the video, so I infer that it is on the northern suburban side. The northeast side is a forest area, and the sun is bound to be blocked by the forest, so the northwest is the most likely."

Old Shao's eyes lit up, and he immediately said, "I will immediately arrange for the police to investigate the cellars in the northwestern suburbs where people can hide."

Unexpectedly, Jiang He just watched the video once, and he has already roughly found the location where the victim was trapped. Such meticulous observation ability and logical reasoning ability made several people around him admire it.

"Is there any way to be more precise?" Yuan Jun said: "Although it is confirmed that it is the northwestern suburbs, the northwestern suburbs are too big."

Jiang He shook his head: "There is no way, there is too little information in the video."

Shao Lao patted the table and said, "Yes, I don't think even a criminal consultant would have thought that we would be able to find this position in the northwest suburbs. What he wants us to do is to start with the woman herself. It seems that we want to Two leads were investigated at the same time."
