The last day of the year is always warm in the cold, and this warmth comes from the lively atmosphere of New Year's Eve. Even though it was approaching the wee hours of the morning, there were still many passers-by on the street who were walking unhurriedly.

Ritsu Sasashima didn't rush back to the car, but bought a can of coffee in front of the vending machine.

Standing at the traffic light at the corner of the street, he looked sideways at the scene of the crime, only to notice a bouquet of flowers on the bench. Confident in his memory, he was sure he didn't see the bouquet when he arrived at the site, and he didn't see it when he bought his coffee.

This bouquet of gardenias had just been put up, and it is very likely that there was some connection to the victim, Atsuko Kasaka.

There are a lot of pedestrians around, and it is definitely not okay to come forward and ask one by one. Ritsu Sasashima looked at the convenience store that was open 24 hours a day, but it was pitch black and there was no sign of business at all.

"It's better for me to close the door."

Quickly burrowed into the alley behind the convenience store, where there was no surveillance camera. Picking the lock can be said to be his "old job", after easily priing the rear window open, he can easily climb into it with dust-free gloves.

Ritsu Sasashima drove to the cash register, turned on the computer and began to check the surveillance video of the previous few minutes. Just five minutes ago, a man and a woman came to the scene of the crime and put down a bouquet of gardenias, then bowed to each other and left.

He adjusted the surveillance footage and zoomed in as close as he could, revealing a metal badge on the backpack in his hand, which could be detected as the emblem of Ibaraki University through investigation and analysis.

Ibaraki University, isn't that the university where the victim Atsuko Kasaka studied?

It seems that there is a new clue that the two of them will come to deliver flowers on New Year's Eve, obviously because the relationship with the victim is not simple, and they are likely to be friends.

Ritsu Sasashima didn't stay in the convenience store any longer, deleted all the surveillance video on the computer, turned off the surveillance, and returned the same way after doing all this, and removed the traces of the lock picking.

When I got back to the car, I just came to the car door and received a complaint from Yuna Hayasaka: "Where did you go?" The burgers I bought for you are all cold, do you want me to buy you another one? ”

Ritsu Sasashima opened the folding laptop and said while manipulating: "I just went to find clues to the murderer, please help me open the hamburger and pick out the tomatoes and onions inside, thank you." ”

"You're a picky eater."

"I just don't think it tastes good in it, and I eat it in a different way."

Send the video directly to Vodka's mailbox, and ask him to help decipher the road surveillance in Ibaraki Prefecture to find as much footage as possible of the assailant.

At this time, vodka in the safe house in Bunkyo-ku, Tokyo, was holding a bottle of water of life and leaning on the sofa to watch the red and white song party, and there were less than ten minutes before the countdown to zero.

Bite.

The sound from the mobile phone made him half sober up, and Vodka picked up the phone in a panic and found that it was not Gin who let out a long sigh.

[Ogier: Vodka, please help me investigate the surveillance video in this area to see if the man is present.] It's really embarrassing to disturb your rest on Chinese New Year's Eve, and I still have a few bottles of fine wine from the collection, and I will bring it to you when the time comes. ]

Was it actually sent by Ogier? Perhaps because of the alcohol, Vodka frowned and said distressedly: "The Metropolitan Police Department actually has to be on duty on Chinese New Year's Eve, it's really too much, it's better to hurry up and let Augier get off work early." ”

In terms of hacking, vodka's technology is not inferior to Ogier's, and even better than speed in some simple cracks.

After self-made software analysis, the man was soon marked in surveillance video at several intersections. After the vodka was sorted out, he packed the edited video and sent it to Ogier's mailbox, he sighed and sighed: "Augier, this guy is too serious at all times, and he won't leave everything to him if he's lazy." ”

Bite.

Soon received a reply, and after opening it and seeing the contents, Vodka couldn't help but smile innocently.

[Ogier: Thank you.] And also... Happy New Year's Eve, drink less alcohol and pay attention to your health. ]

"Hey, hey, hey."

You must know that it is rare in the organization to receive such a blessing email. Vodka silently saved a copy of the letter in his locked mailbox, and the precious letter recording their brotherhood should be kept safe.

Ritsu Sasashima didn't know that the things he sent politely were treated like treasures, so he pushed his laptop towards Yuna Hayasaka and instructed, "Can you help compare the characteristics of the men in these videos, such as movement or pace." ”

"Okay, hurry up and eat, the fries are all over."

"Hmm."

When I opened the wrapper of the burger, I found that the ingredients I hated had been picked clean. Ritsu Sasashima took a bite and chewed it twice, then picked up the cola and took two bites, and sure enough, the cold burger was not very tasty, the cheese inside was solidified, and the patty of the beef burger became dry and juicy.

Yuna Hayasaka stared at the screen carefully and compared the videos, although she was a little curious about where she got these videos, but when she thought of Takashi Onizawa's hacking skills, she still didn't say anything.

After all... This is a bit of a violation.

Five minutes later, Yuna Hayasaka pressed the pause button and said in surprise, "Onizawa, I seem to know the direction of the next investigation!" ”

Eita Kasaka, who was about to fall asleep sitting in the co-pilot, immediately sobered up when she heard this, and said in an excited tone: "Really? Hayasaka-san, did you find anything? ”

"Well, Onizawa, look over here."

After playing several videos repeatedly, Yuna Hayasaka said, "The man kept his left hand on the back of his neck, and it is not clear in these two videos, but this one can see that he is scratching his neck, so I think he may have a skin disease." ”

"And in the two videos here, he took off his hat, and he can see his appearance clearly."

Is it itchy caused by skin diseases?

Ritsu Sasashima nodded in agreement: "It's very likely, combined with the smell of oil on the clothes on the previous body, the search scope can be narrowed down to garages and gas stations, plus the information on left-handers and skin diseases, it should be able to lock the identity of the target." ”

"So we're going to visit now?" Kamio Kibanhei rubbed his eyes and asked.

"The progress of the visit is too slow." After Ritsu Sasashima put the computer on his lap, he coughed dryly: "You can rest for a while, and I'll take care of the rest." ”

In addition to Eita Kasaka, the other two quickly understood Onizawa's intentions. It is nothing more than to use hacking technology to directly investigate the medical records of the hospital, screen the skin disease cases of men around 40 years old, and determine the identity by comparing their appearance.

"Brother Onizawa, how can you check when you stay in the car?" Eita Kasaka wondered.

"Eita, if you want..."

"Ghost, Ze, Chong, don't you take bad children, okay?" Yuna Hayasaka glared at Onizawa, and when she faced Eita, she instantly smiled and said, "Children don't be curious about what adults do, curiosity will kill cats." ”

"You're quite right, curiosity kills cats."

Thinking of a certain high school student who has shrunk to become a national elementary school student, people, it's better not to be too curious.
