"Your consumption methods here are indeed different from ours," Zhao Yu said. "Do you need to pay a credit card to buy a tricycle?"
An hour later, in a quiet office, Zhao Yu was telling Li Zhuzhen and Masako Yangshan about his reasoning.
"The prices are too high," Li Zhuzhen said. "Tricycles are not cheap either! Moreover, there are preferential policies for paying with credit cards."
"Here," Zhao Yu placed a piece of information in front of Li Zhuzhu, "This photo is of Han Cheng and his wife's fish stall. Did you see it? They already have a tricycle!
"For such a small fish stall, a tricycle should be enough, right? Why buy a new one?"
"So..." Yangshan Masako said in surprise, "You discovered the problem? You used your credit card to buy a new tricycle? Oh my god, what kind of brain do you have?"
"The key is," Zhao Yu said, "the timing of their purchase of the tricycle was so coincidental, just before Li Yiyan was killed!"
"So..." Li Zhuzhen said, "Do you think Li Yiyan's death has something to do with them?"
"Yes!" Zhao Yu nodded, "Li Yiyan's body also showed signs of being moved. The only vehicle that can be driven into the park is a tricycle.
"Of course, the reason why I pay so much attention to tricycles is because I just solved the Ghost King case!"
"Oh..." Masako's eyes lit up, "I remembered, it's true that the murderer of the Ghost King case also cleverly used an electric tricycle!
"It's convenient and deceptive. This thing can almost be called the king of murder, right?" Masako said excitedly, "I have to write it down carefully. I will definitely use it in my novels in the future!"
"Of course, you can't be convinced just because of the tricycle," Zhao Yu said. "I carefully studied the 10 families of the victims who participated in the mutual aid meeting, and found that most of them can be excluded, except Cui Dongshan and the others. Only then is there the possibility of taking risks!
“Because they lost their most important or only family member in the bus fire.
“Only a few of them can be dazzled by revenge, and they also have certain abilities.
"So, I think..." Zhao Yu said meaningfully, "The reason why the black-eyed killer selected them from the many family members of the victims is probably because of these points, right?"
"You are really good," Li Zhuzhu said. "Didn't you guess that someone might be pretending to be Kwon Youdong when we went to the bar to investigate?"
“No,” Zhao Yu clarified, “In the bar, based on the driver’s confession, I discovered that Quan Youdong suddenly asked to go home after going to the bathroom, which was a bit abnormal!
"At that time, I just thought that the problem might be in the bathroom.
“The bathroom is not only located on the first floor, but it also has a very open window that can be opened from the inside!
"There is a passage outside the window, which makes me feel particularly strange. In our country, security windows must be installed!"
"Then..." Li Zhuzhu asked hurriedly, "When did you realize that there was something wrong with Cui Dongshan?"
“Last night,” Zhao Yu said calmly, “It wasn’t until last night, when I synthesized all the information, that I realized that someone might have pretended to be Quan Youdong, and that person was Cui Dongshan!
"First of all, you have also seen that if you remove the beard and change the hairstyle, the two of them are very similar in terms of body shape and appearance.
“If you put on clothes and put on a little makeup, it would be difficult to be spotted in that dark environment!
“Secondly,” Zhao Yu added, “I chatted with the driver for more than two hours that day, and the driver mentioned to me about my wallet and sunglasses!
"When the driver took Quan Youdong home, Quan Youdong kept wearing big sunglasses, which was different from usual. He was so drunk, why did he keep wearing them? It was clearly for himself. Pretend to be fake!
"And, only in this way can we explain why Quan Youdong, who has always been too lazy to walk, had to walk back to the villa after arriving home!
"Finally, when I found out that Cui Dongshan had been a soldier before and had also been in the police dog team, this idea naturally became stronger.
"Only then did I realize that they had actually played a trick!"
"That's amazing," Masako exclaimed, "Even so, you didn't say a word to me last night. You are so bad, Detective Zhao!"
"This is not bad. Only if you really give me a bath will you know what bad is!" Zhao Yu complained, "I just need to prepare all the information!"
The two women looked at each other, with black lines showing on their foreheads.
“The report states that no valid fingerprints were extracted from Quan Youdong’s wallet,” Zhao Yu continued, “Obviously Cui Dongshan wiped it last, and he didn’t want to leave his fingerprints on it.
"Also, the autopsy report states that there was a long indentation on Quan Youdong's back. I think it was made on the window sill of the bar bathroom.
"Also, there is a regular but inconspicuous indentation pattern on his back. However, the garden floor of Quanyoudong's house is flat, which is not consistent with the indentation on his back.
"So, I suspect that the place where Quan Youdong was killed may not be his home. It is possible..." Zhao Yu looked at Li Zhenzhu and said, "It was printed on Han Cheng's tricycle!"
"You..." Li Zhuzhu pouted, "Can you tell me earlier?"
After saying that, she quickly walked aside, notified her detectives, and quickly went to look for Han Cheng's tricycle.
"I've seen the marks you mentioned before," Masako asked with a frown, "But there were none on the bodies of Li Yiyan and Liu Bingcheng? Isn't it a tricycle?"
"That kind of indentation is not very obvious. Li Yiyan and Liu Bingcheng are too light," Zhao Yu said. "Maybe they can't be pressed out, but Kwon Youdong is different!"
Beep beep beep... beep beep beep...
At this time, before Li Zhuzhu had time to interrupt, her phone suddenly rang again.
"What?" After answering, Li Zhuzhen immediately widened his eyes and said to Zhao Yu, "On Quan Youdong's sunglasses, dander tissue matching Cui Dongshan's has been found!"
"Great!" Masako clenched her fists excitedly, "This way, we won't be afraid that Cui Dongshan will not plead guilty! I really hope that we can know quickly who the black-eyed killer is!?"
Putting down the phone, Li Zhuzhen said: "I'm disgusted. Cui Dongshan is a naive person. The more such a person ignores our evidence, the harder it is for him to speak!"
"It doesn't matter," Zhao Yu said, "Aren't there Han Cheng and his wife and Park Yushun? How are they? Have they been caught?"
"Close the network immediately," Li Zhuzhen said, turning on the big screen in the office and saying, "It's live broadcast now!"
"Remember," Zhao Yu warned, "after catching someone, strike while the iron is hot!"
"Don't worry!" Li Zhuzhu nodded, then turned up the sound on the big screen, and then sent an arrest message to her men.
After the message was sent, the detectives in the video acted quickly and immediately rushed to the seafood market and pushed the Hancheng couple to the ground while they were cleaning up the fish stall.
At the same time, a detective shouted loudly and asked: "What's your name? Tell me! What's your name?"
"Han... Han Cheng..." The man on the ground said his name immediately without struggling.
"What about you?" the detective asked the woman again.
"Li Xuanmei!" The woman did not struggle and answered extremely calmly.
"You know..." the detective asked according to the designed routine, "Why are you being arrested?"
As a result, Han Cheng's answer surprised Zhao Yu.
But seeing a happy smile on his face, he said with relief and determination: "You know, I am - the black-eyed killer!!!"
