Chapter 1844: Collaborative Murder Theory

"Sister Wu," Zhao Yu asked Wu Xiumin under the amazed gaze of the crowd, "You just said that regarding this case, do you feel that it is difficult to psychologically profile the murderer?"

"Yes!" Wu Xiumin nodded, "On the one hand, there are too few similar cases to conduct effective information comparison; on the other hand, in this case, the murderer's personality seems to have a certain conflict, which always makes my Reasoning creates contradictions."

"That's right!" Zhao Yu said, "If there is more than one murderer, can it explain your second question?"

"More than one person..." Wu Xiumin frowned deeply, "Is there more than one person?"

"It's like this," Zhao Yu said, "Ever since the Guandi Temple case, I've always felt that something was wrong!

"Now it seems that the problem is mostly here!

"Have you noticed that it is actually not an easy task for the murderer to arrange such a complicated killing scene?"

"This..." Everyone was lost in thought.

"Think about it..." Zhao Yu said, "The murderer who killed Niu Jinkui had to investigate Niu Jinkui's living habits in advance and avoid camera surveillance;

"Then, he has to find the location of the crime, familiarize himself with the environment of the crime, and ensure that there will be no interference;

"Secondly, he has to prepare a large number of crime tools, as well as make up and dress up the victim carefully...

"In addition, he will use chemical reagents to decompose tetramine, and inject it precisely into the victim's digestive tract and gastrointestinal tract...

"Besides, he has to anesthetize, tie up, transport and kill the victim, and even arrange the scene, such as the guqin, to dress the victim up as in the ghost king record, which is not a small amount of work. ah!"

"Oh..." Cui Lizhu understood, "So... you think the murderer is not alone, but has an assistant? For example, the second case that happened in the ghost town?"

"Anyway, this is what I felt was wrong before," Zhao Yu said, "I think the case is too cumbersome to handle alone!"

"But..." Wu Xiumin objected, "If careful preparations and rehearsals have been done in advance, it is not impossible for one person to complete it independently, right?

"After all, the autopsy report pointed out that the murderer used a large dose of anesthetic when kidnapping the victim," Wu Xiumin analyzed, "Also, the place and time chosen by the murderer can ensure that no one will be disturbed all night, so he has Full time and conditions for crime!

"I think that as long as the murderer has the strength to drag the victim, he can still do it alone!"

"That's right..." Cui Lizhu scratched her head, "Both Niu Jinkui and Shen Wenbin weigh only 60 kilograms. If you are a slightly stronger person, then carrying them on your shoulders for small-scale transfers is no problem, right?"

"But..." Captain Zhang Ling pondered, "The first case may be completed independently, so what about the second case? Even if there are accomplices, we still have no way to explain the surveillance?"

"Captain Zhang..." Zhao Yu said, "Because it's already dark today, some things may not be clear, how about you ask the experts to check the surveillance tomorrow morning to see if there are any other clues?

"After all, the matter of monitoring is not a trivial matter, maybe it can become the key to solving the case!"

"Okay," Zhang Ling nodded, "I know what to do!"

"Boss, boss... I found it, I found it..." As soon as Zhang Ling finished speaking, Ran Tao quickly ran into the office with his mobile phone and reported to Zhao Yuhui, "We came from a family outside the community where Niu Jinkui's family lived. The tricycle was found in the camera of the private shop!"

"Oh?" Upon hearing the news of the tricycle, Zhao Yu immediately regained his spirits.

"look……"

Ran Tao opened the frozen video in front of Zhao Yu, but saw a blurry tricycle appeared in the video, but Zhao Yu could still tell that this tricycle was very similar to the electric tricycle in the second case.

"It was a barbershop. Because the boss rented the shop, there was a dispute. He was worried about being retaliated, so he installed a camera, and this happened to be taken. Unfortunately, the camera is cheap, and the image is a bit blurry..."

"Then... what about the time?" Zhao Yu asked while watching the video.

"Just right," Ran Tao replied, "the time difference between Niu Jinkui and Niu Jinkui coming out of the community and disappearing into the blind spot was four and a half minutes.

"We simply measured the speed, and Niu Jinkui could walk to the monitored road in 3 minutes, but he didn't show up in the end.

"So, it is very possible that he was kidnapped by this electric tricycle! Oh no, it is the person driving the tricycle!

"Look, Boss..." Ran Tao turned on the phone map again, and pointed out the location of the barbershop, "Here, it happens to be located in a small alley without surveillance!

"So, the murderer took advantage of Niu Jinkui's surprise and stunned him, then loaded Niu Jinkui into a tricycle and left along this path!

"It's a pity..." Ran Tao pointed to another location on the map, "It's a wilderness with a lot of crossed roads. We still need time to catch the movement behind the tricycle..."

"It shouldn't be difficult, right?" Cui Lizhu said, "The tricycle must have gone in the direction of Guandi Temple?"

"Do you still need to remind me?" Ran Tao narrowed his eyes, "I have already sent someone to get the surveillance there!"

"But..." Wu Xiumin shook her head and said, "Even if we can be sure that this tricycle is the same one as in the second case, and that the person driving it is the murderer of the ghost king case, but... the car is completely sealed, we Still can't see the face of the driver?"

"That's right..." Zhang Ling also said not very optimistically, "I sent someone to count before. There are more than 20,000 tricycles of the same type on the market in Quan'an City. Because it is rainy here, people who buy tricycles People like to buy this fully enclosed one!"

"No way?" Zhao Yu pouted, "So many? In other words, this tricycle wasn't modified by the murderer?"

"Yes!" Zhang Ling said regretfully, "It's like this as soon as it leaves the factory. I guess...the murderer must have expected that he would not be able to completely get rid of the camera surveillance, so he chose this most difficult means of transportation, right?"

"A master..." Cui Lizhu sighed, "This is really a master! He has thought of everything!"

"Whether you want it or not...the investigation will continue! So, brother Tao, you can continue to follow up!" Zhao Yu ordered Ran Tao, "After all, this is a very important clue. Might help solve the case!

"And...if we can find a clearer image, maybe we can find out some features from the car, so as to narrow the scope of the investigation!"

"Okay," Ran Tao readily agreed, "I'll continue to investigate!"

After Ran Tao left, Zhao Yu couldn't help feeling uneasy. He was worried that he would not be able to stop the murderer before the next ghost king case happened.

So, he reached out and picked up the photocopied "Ghost King Record" from the table, and then turned to the next article by Mrs. Dou...
