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

"That's right!" Wu Xiumin nodded, "On the one hand, there are too few similar cases to effectively compare information, and on the other hand, in this case, the murderer's personality seems to have a certain conflict, which always makes my reasoning contradictory." ”

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

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

"That's right," Zhao Yu said, "Ever since the case at the Guandi Temple, I've always felt that something is wrong!"

"Now it looks like most of the problem is here!

"Have you noticed that it is not easy for the murderer to set up such a complicated murder scene?"

"This ......," the crowd pondered.

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

Then, he had to find the location of the crime, familiarize himself with the environment in which the crime was committed, and ensure that it would not be disturbed;

Secondly, he has to prepare a large number of tools for committing crimes, and he also has to give the victim meticulous makeup and dressing......

In addition, he had to use chemical agents to break down the poisonous rats, and he also had to inject them precisely into the victim's digestive tract and gastrointestinal tract......

"In addition, he also has to anesthetize, bind, transport and kill the victim, and even have to set up scenes, such as the guqin, to dress up the victim as in the ghost king record, this is not a small amount of work!"

"Oh......" Cui Lizhu realized, "so ...... Do you think the murderer is not a single person, but a helper? For example, in the second case that happened in a ghost town?"

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

"But ......," Wu Xiumin objected, "if you have carefully prepared and rehearsed in advance, it is not impossible to complete it alone, 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 disturbs him all night, so he has enough time and conditions to commit the crime!"

"I think that as long as the murderer has the strength to drag the victim, a person can still do it independently!"

"Yes......" Cui Lizhu scratched her head, "Niu Jinkui and Shen Wenbin both weigh no more than 60 kilograms, if they are a slightly stronger person, then it is okay to carry them on their shoulders and carry out a small area of transfer, right?"

"But......" Captain Zhang Ling pondered, "the first case may be completed independently, but what about the second case? Even if there are accomplices, we still can't explain the monitoring?"

"Captain Zhang......" Zhao Yu said, "Today, because it's already dark, there may be some things that can't be seen clearly, so let's ask the experts to check the monitoring early tomorrow morning to see if there are any other clues?"

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

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

"Boss, boss...... Found it, found ......" As soon as Zhang Ling's voice fell, Ran Tao quickly ran into the office with his mobile phone and reported to Zhao Yu, "We found the tricycle from the camera of a private store outside the community where Niu Jinkui's family lives!"

"Oh?" As soon as he heard the news of the tricycle, Zhao Yu immediately came to his senses.

"Look ......"

Ran Tao opened the frozen video in front of Zhao Yu, but saw a relatively vague tricycle appear in the video, but Zhao Yu could still see that the tricycle was very similar to the electric tricycle in the second case.

"It was a barber shop, because the owner had a dispute with the shop rented, and he was worried about retaliation, so he installed a camera, and it turned out to be filmed just like this, but unfortunately the camera is cheap, and the image is a little blurry......

"That'...... What about the time?" Zhao Yu asked, looking at the video.

"Just right," Ran Tao replied, "and Niu Jinkui came out of the small area and disappeared into the blind spot four and a half minutes apart.

"We simply measured the speed, and Niu Jinkui was able to walk to the monitored road in 3 minutes, but in the end it didn't appear.

"So, it's very likely that he was kidnapped by this electric tricycle! Oh no, it's the person driving the tricycle!

"Boss, look at ......" Ran Tao opened the map on his phone 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 unpreparedness to stun him, and 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 road crossings, and we still need time to capture the movement of the tricycle behind it......"

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

"Do you still need to remind you of this?" Ran Tao narrowed, "I've already sent someone to call up the surveillance there!"

"But ......," Wu Xiumin shook his head and said, "Even if we can be sure that this tricycle is the same as the second case, and we can be sure that the one who drove it is the murderer of the Ghost King case, but...... The car is completely enclosed, and we still can't see the driver's face?"

"That's right......" Zhang Ling also said not very optimistically, "I have sent someone to count before, there are more than 20,000 tricycles of the same type on the market in Quan'an City, because we have a lot of rain here, so people who buy tricycles like to buy this kind of fully enclosed!"

"Wouldn't it?" Zhao Yu pouted, "So much? In other words, this tricycle was not modified by the murderer?"

"That's right!" Zhang Ling said regretfully, "As soon as it leaves the factory, it's like this." 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 to find, right?"

"Master......" Cui Lizhu sighed, "This is really a master!

"Whether you want it or not...... So, Brother Tao, you continue to follow up!" Zhao Yu ordered Ran Tao, "After all, this is a very important clue, if you can restore part of the trajectory, it may also help solve the case!"

"And...... If we can find a clearer image, we might be able to find some features on the car and narrow down the scope of the investigation!"

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

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

So, he reached out and picked up the photocopied copy of "Ghost King Lu" from the table, and then turned to the next article of the Dou family's daughter......
