After Yamamura left Shinji's house in Asakura, he trotted all the way to the nearest convenience store. Although it is already autumn in November, the temperature is still high today, and if you want to use a popsicle to create a time-lapse device, you can't leave the freezer for too long.

The killer would definitely choose to bring his own popsicles when he was not sure if there were popsicles in the victim's home, so he would definitely buy them around the eucalyptus scene.

When Yamamura Cao ran into the convenience store, he almost collided with the automatic sensor door, he anxiously stepped in place, but unfortunately the sensor door was indeed a bit old, and after slowly opening it, he came to the cash register, wiped the sweat from running, and asked aloud: "Hello, I'm a criminal police officer from Gunma Prefecture, do you sell Toyo food brand popsicles in your store?" ”

"Yes, every flavor is in stock."

"Do you remember when someone came to buy popsicles today?" The cashier shook his head, he pointed to the shopping receipts piled up next to him, and said, "I can't remember this a little, you can see if there are any shopping receipts that the customer doesn't want." ”

"Okay, I'll trouble you to call up the in-store surveillance."

"No problem." Yamamura carefully checked the shopping receipt, and finally found the Tomayo Foods brand marble soda popsicle on the shopping receipt at 10:27 in the morning, and only bought one, and did not buy anything else.

That's it! After the cashier helped pull up the surveillance video, Yamamura noticed that a tall man in a white jacket appeared in the picture, he deliberately lowered the brim of his baseball cap so that he couldn't see his face clearly, and the hand reaching for the freezer was still wearing gloves, so he could only tell that his dominant hand was left.

Left-handed, white jacket, male, about 1.75 meters tall. Yamamura Cao summed up this information and found that he couldn't match the three suspects at all, could it be that the inferences of himself and the predecessors of the Eagle Division were wrong, and the murderer was not among the three?

He took out his mobile phone to turn on the video recording function, and after recording the surveillance video, he did not forget to take the shopping receipts with him.

Yamamura Cao, who returned to the Asakura Mansion, did not look excited at all when he left, and he walked to Sosuke Takaji's side dejectedly, and sighed, "Takaji-senpai, our inference seems to be wrong, the person who bought the popsicle is completely different from the three suspects. ”

"Really?" Fujiwara Yu reached out and took the mobile phone, he looked carefully at the surveillance video taken by Yamamura Cao, and did not rush to make a conclusion after noticing that the murderer was left when he took the popsicle, and when he saw the picture of the next payment, his brows couldn't help but provoke, and it was really the same as what he thought.

He handed the mobile phone to Yamamura, and did not rush to say the answer, but asked, "Yamamura, have you watched the surveillance video carefully?" ”

"Huh? I've seen it three times. ”

"No matter how good the test results are, the candidates should also develop the habit of carefully marking the papers and checking them afterwards, and you will read them carefully from beginning to end." Yamamura nodded, and after he re-watched the video, he realized that he had made a big mistake.

That is, when he saw the murderer stretching out his left hand to take the popsicle, he directly thought that the other party was a left-hander, so much so that he ignored that after he paid, the hand that took the change and put it in his pocket was his right hand.

The murderer wanted to hide the fact that he was right-handed, and he stretched out his left hand to confuse the public, but unfortunately he still made a mistake when he took the change, which led to exposing the essence of being right-handed.

Fujiwara Yo's eyes fell on one of the people sitting on the sofa, and the corners of his mouth raised slightly: "Not only that, but with this video alone, we can determine who the murderer is, and he is also smart but mistaken by cleverness." ”

"Huh? Senior, do you already know who the murderer is? Yamamura was surprised. Fujiwara Yu nodded, he walked towards the three of them, and asked a question that made everyone present a little puzzled: "Who paid for the purchase at the convenience store just now?" ”

"I paid for it." Shigeiwa Nishimura subconsciously raised his hand, and he continued to explain, "Because we said that we would sing karaoke after the party, Kazama-san would bear the cost of karaoke, and Shibata-san would bear the cost of buying drinks and snacks during the period. ”

"In other words, Shibata didn't pay, right?" Shibata Tatsuaki didn't expect the topic to suddenly turn to him, he reached out and touched the tip of his nose, nodded and said, "I really didn't pay, is there anything wrong with this?" ”

"Then can you explain why there are no fingerprints on the 860 yen in your right pocket?" Shibata Tatsuaki couldn't help but be stunned when he heard this, he reached out and wanted to take out the coins in his pocket, but his wrist was restrained by Fujiwara Yoshi, he frowned and said loudly: "Let go, do you police do this way?" What right do you have to hold my hand! ”

"Yamamura, you come and take out the coins."

"Yes!" Yamamura's gloved hand reached into Tatsuaki Shibata's pants pocket, and when he took out a few coins, he found that it was 860 yen, no more, no less.

He was a little surprised, not because the amount of money was correct, but because he felt that the predecessor he longed for also liked Toyo popsicles, otherwise how could he know the unit price of popsicles at convenience stores.

Fujiwara Yoshi looked at Tatsuaki Shibata with a panicked face, and a harmless smile on his face: "Mr. Shibata, there shouldn't be your fingerprints on this coin, right?" After all, when you go to buy popsicles for eucalyptus, you wear gloves. ”

"Oh, Officer Eagle Division, I don't understand what you're talking about, but there just happen to be a few coins without my fingerprints, how can you frame me as a murderer? You know, I received a call from Mr. Asakura, which proves that the teacher was not dead when he called, so how could I complete this series of operations right under your noses! Tatsuaki Shibata retorted pretending to be clever.

is still pretending to be stupid, it's really a thief. Fujiwara Yu picked up the remote control board of the air conditioner in the physical evidence bag and told the murderer's criminal process: "After the murderer committed the crime, he used the popsicle to make a time-delay device, as long as the popsicle was placed in this position of the bookcase, and a heavy object was placed on it, and when the popsicle melted and the weight fell, the remote control board of the air conditioner placed below would be pressed, and the refrigerated air conditioner would automatically turn off." Today's outdoor temperature is quite high, and if you want to slow down the melting speed of the popsicle, as well as delay the time of death, the murderer will naturally turn on the refrigeration and air conditioning, in order not to be noticed by others, so he deliberately set up such a delay device, am I right? Mr. Shibata. ”

"How do I know, you ask me? I'm not a murderer! ”

"Then why are you wearing the murderer's clothes?" Hearing Takaji Sousuke's words, Yamamura Cao also adjusted the surveillance video of the convenience store very cooperatively, he raised his hand in front of Shibata Tatsuaki, and scolded coldly: "Say! Why wear the murderer's clothes! ”

"I said, Mr. Officer, are you blind? The man in the picture is obviously wearing a white jacket, but I'm black! Shibata Tatsuaki clasped his hands in front of his chest and raised his chin with a haughty look, but soon he couldn't laugh.

Because Fujiwara Yu directly grabbed his collar and tried to take off the jacket on his body, Shibata Tatsuaki, who was worried that the matter would be exposed, naturally covered his clothes and yelled.

But no matter how hard Tatsuaki Shibata tried, he couldn't resist the power of Sosuke Takaji, and finally his jacket was taken off.

Fujiwara Yu directly turned the jacket over, and he had seen a lot of jackets that could be worn on both sides, so he observed the other party's outfit after locking up the murderer.

He raised the jacket that had turned white in his hand with a calm face, and asked patiently, "Black?" So do you want to explain, what color is it now? ”
