When passing by the basketball court, Xia Shi called Xia Jinyu aside alone and confirmed An Ziyang's alibi to him. As An Ziyang said, yesterday evening, several of them did eat at a hot pot restaurant near the school, and An Ziyang paid for it.

From this point of view, An Ziyang is indeed not the murderer of Ma Zhichen, but does Ma Zhichen's death really have nothing to do with him?

Xia Shi considered the possibility of hiring a murderer, but when he thought about it carefully, he felt that it was unrealistic. An Ziyang's family is not wealthy, and in recent years, he has not saved much money to treat his mother, and he does not have the financial strength to hire a murderer. Borrowing money and taking out loans can solve the problem of money, but this needs to be further verified.

Xia Shi didn't believe it anyway, An Ziyang sent that threatening text message to Ma Zhichen just to scare the other party, he must have done something, or planned what he was going to do. He suddenly thought of the clownfish that the murderer had stuffed into the victim's mouth, and his mood couldn't help but feel a little heavier.

This case is not simple. Again, he admonished himself. It is clear that the suspect is in front of him, but the answer is becoming more and more ambiguous. Could it be that he really got the wrong direction and was limited by his subjective consciousness to solve the case?

"Brother, what case has An Ziyang been involved in?" Xia Jinyu sensed the seriousness of the matter and asked Xia Shi again.

Xia Shi frowned, and replied coldly: "Jin Yu, this matter has nothing to do with you, don't ask more." ”

"Is it related to An Ziyang's mother?"

"Huh?" Xia Shi was stunned for a moment, looked at Xia Jinyu in surprise and asked, "How do you know?" ”

"I guessed, it seems to be right?" Xia Jinyu raised the corners of his mouth slightly, and said to Xia Shi, "Your investigation of An Ziyang's alibi shows that he is suspected of a certain case and is likely to be the main suspect in the case." And you, who have always been only responsible for the investigation of major cases, are busy with work, and have every opportunity, it is impossible to go out in person for an ordinary small case, so An Ziyang must be suspected of a homicide, and it is not a simple homicide.

"An Ziyang is my classmate, roommate, and good friend, I know him as a person, he is definitely not the kind of young man who will cause trouble outside, and it stands to reason that he will not have anything to do with the murder, but he can't hide from the suspicion of revenge and murder, because he has an enemy he dreams of killing, and that person is the driver who caused a drug driving accident and killed his mother a few years ago. Once something happens to that person and the police find him, it becomes logical to investigate him.

"So, you and your father were too busy to celebrate the Mid-Autumn Festival yesterday, it must be because a very serious case happened yesterday, and the victim of the case should be the one who killed An Ziyang's mother, am I right?"

Hearing this, Xia Shi was stunned for a long time before he shook his head with a smile, reached out and grabbed Xia Jinyu's hair, and said with a gentle expression: "You, let me say something, obviously I didn't even get into the police academy, and I still dream of being a detective." ”

"What's wrong with not getting in?" Xia Jinyu pursed his lips unconvinced and said, "That's not because my physical condition was not very good at the time, it's a big deal that I will take the civil service exam after graduation, and I can't go out of the field, and I can do a civilian job." Otherwise, I will also be a special consultant for you like Brother Gu Song. ”

"Just you, you still want to be our advisor? Do you have someone who has that two? ”

"Why, look down on me? Another day, I will go to Brother Gu Song to learn art, and I will definitely impress you when the time comes. ”

"Forget it, Detective Gu is too lazy to teach you." Although Xia Shi said this, he knew very well in his heart that in the past period of time, Xia Jinyu had indeed learned a lot from Gu Song, and this child himself was also very spiritual, with a strong sense of justice and selfless dedication, and he would definitely become a very good policeman on the ten days of the holiday.

However, just like his father, Xia Shi couldn't bear to let Xia Jinyu enter this industry. He and his father are both front-line criminal policemen, have experienced countless dangers, and have traveled on the line of life and death several times. Rather than realizing his personal ideals and getting ahead, he hopes that Xia Jinyu can live peacefully, even if he wastes his talent or even has a mediocre life.

Sometimes, being alive is the greatest happiness in life, especially for those of them who deal with criminals every day and die in the line of duty every time they don't know what time they do not know it.

"Okay, don't take the topic away, let's talk about An Ziyang." Xia Shi returned to a serious expression and continued to ask, "Did An Ziyang mention to you that he wanted to avenge his mother?" ”

"Brother, you don't really think that case has anything to do with him, do you?"

"It doesn't matter if it's okay, we'll judge for ourselves, just tell the truth what you know."

"Okay." Xia Jinyu sighed helplessly and said slowly, "On the night of September 30th, An Ziyang told me for the first time about what happened to his mother. As he drank, he told me that sooner or later he would have to pay a terrible price for that person. At the time, I thought he was just talking about it and not really putting it into action. But ......"

Xia Jinyu paused for a few seconds, revealing a hint of uncertainty in his eyes. "Afterwards, I seriously thought about it and found that An Ziyang's behavior was indeed a bit strange recently. He skipped class more often, sometimes not seeing anyone for a day, not knowing what he was doing secretly. What I said is just the objective facts I have heard and seen, and you can consider for yourself whether it will help solve the case. ”

"Well, thank you for telling me this."

After leaving the court, Xia Shi called Huo Yanhui, who was in charge of verifying An Ziyang's alibi with other students, and the two returned to the No. 4 boys' dormitory building again.

In the corridor, they happened to meet An Ziyang, who had washed up and changed into a basketball uniform, and the latter obviously didn't understand what was going on, stopped, looked at the two people in surprise and asked, "Are you here to find me?" ”

"An Ziyang, when did you start tracking Ma Zhichen? How long have you been following him? Xia Shi asked bluntly.

"What?" An Ziyang's eyes widened, and the corners of his mouth twitched twice involuntarily, "I, follow Ma Zhichen?" ”

"Don't pretend!" Seeing An Ziyang's unnatural reaction, Xia Shi knew that he had already guessed eight or nine, so he said impatiently, "I gave you the opportunity to 'confess and leniency' just now, but now I can only ask you to go back to the criminal police team for investigation." ”

Shiqiao Market is the most famous flower, bird and fish market in R City, covering the largest area, gathering the most merchants and operating the most complete varieties. Early this morning, Gu Song and Qi Ruonan came here, shuttling through the area where aquarium supplies, accessories, and fish are handled, and they are very busy. It's just that the purpose of the two of them is not to buy fish, but to investigate the clownfish that the murderer left at the scene of the crime.

Putting aside the murderer's purpose for doing this for the time being, starting from the way he got the clownfish, there are three main ways to consider.

First: The murderer originally raised clownfish, and he could achieve his goal by taking one out of his own fish tank and bringing it to the scene of the crime. This is the easiest and most straightforward method, and the police are most inclined to this.

In response to this investigation, the main focus is to visit the merchants who sell saltwater fish tanks on the market (including the Internet), because the indispensable condition for raising clownfish is to have a complete set of breeding equipment.

In general, a complete set of equipment, including fish tanks, all kinds of equipment, sea anemones, corals and other marine creatures, as well as scattered small objects, add up to thousands of yuan, more than tens of thousands of yuan, and in the future, it will be necessary to maintain and replace the creatures, which is quite expensive. Therefore, if the murderer raised marine fish by himself, at least it means that his economic conditions are not bad.

In addition, some aquarists like to join hobby groups, discuss their own breeding experience, and may also meet, organize activities or something, maybe through this way to find some information.

Second: In order to commit the crime, the murderer may temporarily buy clownfish from the market. Because the clownfish is a saltwater fish, if the murderer does not have the conditions to raise it, the fish he bought back will die quickly, then the time when he bought the clownfish must be very close to the time of his crime.

When Dr. Chen performed an autopsy, he also performed an autopsy on the poor clownfish and confirmed that the time of its death was between 5 and 6 p.m. on the day of the crime, which was not much the same as the time of the victim's death. That is, if the killer bought the clownfish temporarily, he most likely bought it yesterday. Investigate all the shops selling clownfish in the city, and if you can find a buyer who matches the killer's physical characteristics, then he may be the suspect in this case.

Third: The killer may have easy access to the clownfish, such as aquarium staff, or relatives and friends who keep the fish. Ditto, the time he got the fish was supposed to be yesterday. It is easier to investigate aquariums because there are not many in the city combined. The situation of clownfish raised by relatives and friends can be directly combined into the first point to investigate.

Although at first glance it seems that the amount of work involved in investigating this matter is very large, and it is even a bit like looking for a needle in a haystack, it is indeed a very important clue and the biggest difference between this case and other cases.

There are many fish sellers in Ishibashi Market, but there are only a few people who deal in marine fish. Gu Song and Qi Ruonan spent two hours asking all the merchants one by one, but they all said that no male customer with a height of about 1.8 meters and a weight of 1670 pounds had ever bought a clownfish yesterday.

In addition, they also collected some information from merchants who have purchased seawater fish tanks and spare parts, which is not comprehensive, but can be used as a reference. Of course, the merchants themselves should also be within the scope of their investigation.

After doing these things, Gu Song and Qi Ruonan rushed to the next flower, bird and fish market non-stop, expecting to gain something there.
