Lugo stood on the street and shook his head and muttered: "On the way we came here, all the intersections were monitored, why didn't there be one at this intersection?" ”

Ma Jing said: "The murderer did not leave any clues at the scene of the crime, and he was expecting to use the poisoned cake as a breakthrough, but now it seems that he can't count on it." ”

"Don't be discouraged, although there is no surveillance, look at this cake shop," Xu Dijon said. ”

Everyone looked at it together, and after looking for a while, they found that the cake shop had surveillance, and the camera was on the top of the roller shutter door.

Liu Bohong said: "Don't be too happy. ”

"Why?"

Liu Bohong took a few steps forward and said, "The collision between Zhao Kelong and the person riding the electric car should be in this position, you look at the distance from the monitoring." ”

"You mean this location isn't in the surveillance range?"

"If the camera wasn't facing down at 45 degrees, it should be able to be monitored from this position."

Ma Jing said: "Whether it has been monitored or not, we will find it clear when we check it." ”

Xu Dirong, Lu Ge and Ma Jing walked towards the cake shop, knocked on the door to check the surveillance, Xu Dijon walked halfway to the mobile phone rang, it was Xiao Wang calling, before he took the poisoned dog and the rest of the cake back to the police station for identification, now it must be the result is out, Xu Dirong answered the phone and listened carefully.

It's half past two in the morning, Lu Ge took out the strength he had knocked on Dong Linghua's door before, and knocked on the rolling shutter door of the cake shop, the rolling shutter door is easier to make than the wooden door of Dong Linghua's house, and the noise is so loud that the owners of the adjacent shops are noisy, and they come out to see what is happening in their clothes, but the owner of the cake shop does not move, which is very strange, unless the owner is not there.

"Don't knock." Xu Dirong answered the phone and said, at this time, his whole person was like a deflated ball, without energy and listless.

"What's wrong?"

"Xiao Wang called and said that the cause of the dog's death had been clarified."

Liu Bohong said: "Wasn't it just poisoned by the cake? ”

Xu Dijon scratched his head a few times, as if he was annoyed by the mistake he had made, "We don't have conclusive evidence that the cake is poisonous. ”

"That dog is dead, that's proof!" Liu Bohong said.

"Poisoning a person requires an autopsy! Before the results of the identification, we arbitrarily believed that the dog had been poisoned. ”

Ma Jing asked a little anxiously: "What is the result of Xiao Wang's identification, the dog was not poisoned, how did it die?" ”

Xu Dijon thought for a while and said, "Actually, the dog was poisoned. ”

Seeing that everyone was in a circle for a while, Liu Bohong explained in detail: "That cake is a chocolate cake, and the problem lies in the chocolate, which is processed from cocoa beans and contains a variety of derivatives of methylxanthines, such as caffeine and theobromine." Chocolate contains theobromine, which acts on the dog's central nervous system and heart muscle, thus poisoning the dog. We humans can digest theobromine through metabolism, but the dog's digestive system does not. ”

Liu Bohong heard this and shouted: "The dog was not poisoned." ”

"Dogs are poisoned, poisoned by chocolate."

Ma Jing said: "Anyway, it means that no one poisoned the cake." ”

"We've been wasting hours on the poisoning of the cake, the investigation has gone in the wrong direction for hours, and we have to stop there," Xu Dijon said. ”

"Now I have a deep sense of frustration that I thought we could use the poisoned cake as an entry and find out the murderer," Lugo said. ”

At this time, Dong Linghua questioned the police's ability to handle the case, and said: "You told me at home that the cake that Zhao Kelong bought for me was poisonous, and I actually didn't believe it at the time, but you swore by it, and you said it so well that you wanted to have conclusive evidence, and you never expected it to be chocolate." ”

Ma Jing said: "I remember when you heard that the cake was poisonous, you didn't question it, but believed it. ”

Xu Dijon said: "Okay, don't talk about this, we have wasted a lot of time, don't waste time on words anymore." ”

Lugo said: "The entry point of the poisoned cake is gone, what is the direction of our investigation next?" ”

"Lottery!" Xu Dirong said, "Dong Linghua told us that this clue is very important, and it is a new entry point. ”

At this moment, Zhao Youwen lowered her head and looked at her mobile phone, as if she was in contact with someone, Zhao Youwen deeply felt that her father's death might really be related to the lottery, and it was foreseeable who her father's death was related to.

Seeing that the police began to investigate the case from the lottery, the timid and suspicious Dong Linghua was a little overwhelmed, and she was really worried that the police would list herself as the first suspect.

Xu Dirong didn't even look at Dong Linghua, but thought of an important piece of information, took out a small book from his pocket, which recorded the eight questions in this case, Xu Dirong read these eight questions, and didn't find the one he needed, it seems that he was negligent at that time and didn't pay attention to it.

Xu Dirong asked: "Zhao Youwen, your father replaced the anti-theft lock at home with a more advanced fingerprint recognition smart electronic lock a few days ago, which intelligently identifies your father's fingerprint, not even yours, right?" ”

"That's right, that's right."

"That's right, there was no important information about the lottery before, and I was just surprised by Zhao Kelong's change of locks, so I didn't list it as a question."

Dong Linghua asked, "What's right?" ”

Lu Ge understood what Xu Dirong meant, and said: "I understand, I understand why Zhao Kelong wants to change the lock, it is enough to install an anti-theft lock in an ordinary family, and the reason why Zhao Kelong wants to install a smart lock, and he can only identify his own fingerprints, which shows that there is an extremely important thing in the family, and this thing is the lottery that won the grand prize." ”

Ma Jing has her own opinion on this, saying: "I don't agree with your statement, I don't think Zhao Kelong's lock change has much to do with the lottery." ”

Lugo asked, "What basis do you have?" ”

"Suddenly won the jackpot, from the perspective of human nature, in fact, no matter where the lottery ticket is placed, Zhao Kelong will not rest assured, the most reassuring place for him should be to carry it with him at any time, even when sleeping. What did Zhao Kelong do when he changed the lock? Do you want to leave your lottery ticket at home for a long time? This is unreasonable, in order to avoid long nights and dreams, in fact, it is best to go to claim the prize as soon as possible. ”

Xu Dirong hurriedly took out the small book again, glanced at the sixth question above, nodded with satisfaction, and said, "Ma Jing, thank you!" ”

Seeing the captain praising herself, Ma Jing thought that the captain agreed with her judgment, and said proudly: "It's nothing, I'm just reasoning normally." ”

"Don't get me wrong," Xu Dirong hurriedly waved his hand, "I don't agree with your judgment, but you inadvertently helped me answer the sixth question in this little book." ”

Ma Jing showed a puzzled expression.

Xu Dirong said: "At noon today, Zhao Youwen brought a cake to Zhao Kelong for his birthday, Zhao Kelong asked him to wait until the evening, saying that he was going out, and now it can be determined that Zhao Kelong went out for two things, one is to see Liu Bohong, and the other is to celebrate his birthday with Dong Linghua." In the evening, before Zhao Kelong entered the bathroom, he said that he was going out the next day, and Zhao Youwen asked where to go, but he did not answer. Ma Jing just said that in order to avoid long nights and dreams, it is best to go to claim the prize as soon as possible, so can we be sure that Zhao Kelong will go out the next day to claim the prize! ”

Lu Ge smiled, "I didn't expect that Ma Jing inadvertently answered the sixth question, what a coincidence!" ”

Ma Jing said: "This way to answer the sixth question can barely be said, but do you really think that Zhao Kelong changed the lock because he put the lottery ticket in the room?" ”

Xu Dirong said: "You just have doubts about this from human nature, then I will also relieve you from human nature, a person walking on the street with a hundred yuan, he will walk very normally, if this person is carrying millions of checks, he will be suspicious when he walks on the street, someone passes by him, he will feel that this person is deliberately close to steal his check, in short, there is paranoia, Zhao Kelong may be delusional after winning the lottery all day long, someone pries open the door to steal his lottery ticket, so he changed the lock." ”

Ma Jing turned to ask Zhao Youwen, "You should know something about your father, what are the chances of him having this paranoia after winning the lottery?" ”

As for why her father changed the smart lock, Zhao Youwen doesn't know, but it is certain that her father changed the lock definitely not because of the lottery, Ma Jing's judgment was right, but Zhao Youwen didn't tell the truth, just shook her head, saying that she didn't know, and looked at the mobile phone in her hand from time to time, as if she was still in contact with someone.

family: Song Ti; font-size:10.5000pt; mso-font-kerning:1.0000pt; > At this moment, Zhao Youwen fell into deep thought, wondering if her father's death had anything to do with the lottery, and after a while, fear appeared on her face, as if she had thought of something fearful.

Now, the police car came to the intersection of joy, this is a T-junction, but everyone is not calm when they come here, they have got out of the car and looked at it, dumbfounded, no, damn! There are no traffic lights installed at this T-junction, there is no surveillance, and it is impossible to investigate whether the poisoned cake is related to the person riding the electric bike.
