Under everyone's surprised gaze, Zhao Yu asked Wu Xiumin, "Just now, you said that regarding this case, do you feel that it's difficult to profile the murderer?"
"Yes!" Wu Xiumin nodded. "On the one hand, there are too few similar cases, so it's impossible to make an effective comparison. On the other hand, in this case, there seems to be a certain conflict in the murderer's personality, which always contradicts my reasoning."
"That's right!" Zhao Yu said. "If there is more than one murderer, does that explain your second question?"
"More than one murderer …" Wu Xiumin frowned deeply. "More than one murderer?"
"Well," Zhao Yu said. "Ever since the Guan Di Temple case, I've always felt that something was wrong!"
"Now it seems that the problem is most likely here!
Have you noticed that it's actually not easy for the murderer to set up such a complicated murder 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 and avoid surveillance cameras.
Then, he had to find the crime location and familiarize himself with the crime environment to ensure that he would not be disturbed.
Secondly, he had to prepare a lot of tools for the crime, and he had to dress up the victims carefully.
In addition, he had to use chemical reagents to break down the tetramine and accurately inject it into the victim's digestive tract and gastrointestinal tract.
In addition, he had to anesthetize, tie up, transport, and kill the victims. He even had to set up the scene, such as the guqin. He had to dress up the victims like the characters in the Ghost King Record. This was a lot of work! "
"Oh …" Cui Lizhu understood. "So … you think the murderer isn't alone, but has a helper? 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 that the case is too complicated, and it's impossible for one person to handle it alone!"
"But …" Wu Xiumin objected. "If he had carefully prepared and practiced in advance, it's not impossible for him to do it alone, right?
"After all, the autopsy report indicated that the murderer used a large dose of anesthetic when he kidnapped the victims," Wu Xiumin said. "Also, the murderer chose a place and time to ensure that no one would disturb him all night, so he had enough time and conditions to commit the crime!
"I think that as long as the murderer has the strength to drag the victim, he can still do it alone!"
"Yes …" Cui Lizhu scratched her head. "Both Niu Jinkui and Shen Wenbin weigh less than 60 kilograms. If a slightly stronger person carries them on their shoulders, it shouldn't be a problem, right?"
"But …" Captain Zhang Ling pondered. "The first case might have been completed independently, but what about the second case? Even if there are accomplices, we still can't explain the surveillance, right? "
"Captain Zhang …" Zhao Yu said. "Because it's already dark today, there may be some things that can't be seen clearly. How about this? Tomorrow morning, you ask the experts to check the surveillance again to see if there are any other clues?
"After all, the surveillance is not a small matter. It might be the key to solving the case!"
"Okay," Zhang Ling nodded. "I know what to do!"
"Boss, boss … We found it …" As soon as Zhang Ling finished speaking, Ran Tao ran into the office with his mobile phone and reported to Zhao Yu, "We found the tricycle from the surveillance camera of a private shop outside the community where Niu Jinkui's family lives!"
"Oh?" Hearing about the tricycle, Zhao Yu immediately became excited.
"Look …"
Ran Tao opened the video in front of Zhao Yu. In the video, there was a blurry tricycle. However, Zhao Yu could still see that this 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 he rented, he was worried that someone would take revenge on him, so he installed a camera. Unfortunately, the camera was cheap, so the image was a bit blurry …"
"Then … What was the time?" Zhao Yu asked, looking at the video.
"Just right," Ran Tao replied. "It was four and a half minutes after Niu Jinkui came out of the community and disappeared into the blind spot.
We measured the speed, and Niu Jinkui could have walked to the main road with surveillance cameras in three minutes, but he didn't show up.
So, it's very likely that he was kidnapped by this electric tricycle! Oh, no, it's the driver of the tricycle!
"Boss, look …" Ran Tao opened the map on his mobile phone and pointed out the location of the barber shop. "This is a small alley without surveillance cameras!
So, the murderer knocked Niu Jinkui out, put him in the tricycle, and left along this path! "
"It's a pity …" Ran Tao pointed to another location on the map. "It's a wilderness with many intersecting roads. It will take us some time to catch the tricycle's movements …"
"This shouldn't be difficult, right?" Cui Lizhu said. "The tricycle must be heading in the direction of the Guan Di Temple."
"Do I need you to remind me?" Ran Tao squinted. "I've already sent someone to get the surveillance cameras there!"
"But …" Wu Xiumin shook her head and said, "Even if we can be sure that this tricycle is the same as the one in the second case, and we can be sure that the person driving it is the murderer of the Ghost King Case, the tricycle is completely enclosed, so we still can't see the driver's face!"
"Yes …" Zhang Ling said. "I've sent someone to count before. There are more than 20,000 tricycles of the same type on the market in Andu. Because it rains a lot here, people who buy tricycles like to buy this kind of fully enclosed tricycle!"
"No way!" Zhao Yu pouted. "So many? In other words, this tricycle wasn't modified by the murderer? "
"Yes!" Zhang Ling said regretfully. "It was like this as soon as it left the factory. I guess the murderer must have known that he couldn't completely get rid of the surveillance cameras, so he chose this kind of vehicle, which is the most difficult to find. "
"Master …" Cui Lizhu sighed. "He's really a master! He actually thought of everything! "
"Whether we can get it or not, the investigation has to continue! So, Tao, continue to follow up! " Zhao Yu ordered Ran Tao. "After all, this is a very important clue. If we can restore part of its trajectory, it may help us solve the case!
And … If we can find a clearer image, maybe we can find some features from the tricycle and narrow down the scope of the investigation! "
"Okay," Ran Tao 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 the Ghost King Record from the table, then turned to the next chapter of Mrs. Dou.
