Chapter 168: Grasping the Clues (22)

"Ah sneeze——!"

Masumi Sera, who had just sat down on the chair, suddenly covered his mouth and sneezed.

"Sister Shira, do you have a cold?"

The beautiful traffic policewoman Yumi Miyamoto from the Metropolitan Police Department's Traffic Division cast a concerned look at Masumi Sera and asked softly.

"That's impossible. I'm very strong."

Masumi Sera reached out and touched his forehead, but he didn't feel any fever.

She guessed in her heart that someone might be talking about her behind her back, but she didn't care and continued to look at the computer screen in front of her.

"The temperature has fluctuated greatly recently, so remember to add more clothes, Sister Sera."

Yumi Miyamoto said something of concern and then sat next to Masumi Sera.

Half a month ago, Yumi Miyamoto agreed to let Masumi Sera come to her house to check the highway surveillance video of the car accident that occurred on August 8 last year.

And today is the day that Yumi Miyamoto and Masumi Sera had agreed to have their future sister-in-law come to their house to check the surveillance video.

Yumi Miyamoto skillfully pulled up the surveillance video at the entrance of the national highway, and then said to Masumi Sera:

"This is the surveillance video of the national highway entrance closest to the accident scene."

"The accident happened around 8:40 p.m., and it would take about 50 minutes to get from the entrance to the scene of the crime at a speed of 15 km/h."

"The entrance is about 12.5 kilometers from the crime scene..."

After hearing Yumi Miyamoto's description, Masumi Sera calculated the distance directly in his mind.

Then I heard Miyamoto Yumi continue:
“我们排查了8点15分到8点33分之间所有进入了国道的摩托车,这样可以囊括平均时速从30km/h到110km/h的所有摩托车。”

Upon hearing this, Masumi Sera nodded again, thinking that there was nothing wrong with the traffic department's investigation method.

After all, it was on the national highway, and a motorcycle driving too fast or too slow would arouse suspicion.

The range chosen by Yumi Miyamoto is already quite large, and should have included the murderer.

"In those 18 minutes, the number of motorcycles that entered the national highway exceeded 400, and there were about 37 black motorcycles that matched Akikawa Sosuke's description, with riders also wearing black clothes."

"We then used the surveillance video at the exit to rule out 26 of the motorcycles."

"Because based on the time it takes them to enter and exit the national highway, they would not have had time to kill anyone."

“And of the last 11 motorcycles, six of them were traveling with friends who were riding the same motorcycle.”

"In other words, only five motorcycles were travelling alone in the end and had the time to commit the crime."

"Then, through investigations during this period, we ruled out the suspects of the owners of four of the motorcycles."

"What about the last one?"

Sera Masumi asked.

"The license plate of the last car was blocked by something when it entered the national highway, so the identity of the owner has not been confirmed so far."

"What about the exit location?"

"This is the strange part. We compared the surveillance cameras at several exits and didn't find the motorcycle."

Yumi Miyamoto said.

"Ok?"

Masumi Sera felt something was wrong when she heard what Yumi Miyamoto said.

Yumi Miyamoto played the video of that section and pointed the motorcycle to Masumi Sera.

Since the camera was facing the entrance and the rider was wearing a motorcycle helmet, his appearance could not be seen clearly at all.

But judging from her figure, the motorcyclist should be a woman, and she is quite slim.

The motorcycle driven by the other party quickly passed through the entrance, and as Yumi Miyamoto said, the license plate of the motorcycle was obscured.

After memorizing the appearance of the motorcycle and the rider's clothes, Masumi Sera asked Yumi Miyamoto to switch the view to the exit.

Then she began to quickly browse the surveillance video.

"It really disappeared." Masumi Sera dragged the progress bar while staring at the computer screen.

She checked the surveillance footage at several exits several times but couldn't find the slim female motorcyclist.

"Is it possible that after committing the crime and fleeing the scene, the man found an opportunity to turn around and drive out through the entrance?"

"impossible."

Yumi Miyamoto directly denied Sera Masumi's guess.

"There are metal guardrails and isolation strips between the forward and reverse lanes of the national highway, so it is impossible to turn around on the national highway."

"But no matter how you think about it, it's impossible for a motorcycle to disappear on the national highway out of thin air."

"Unless there was a large truck on the highway to pick her up, she hid in the truck after committing the crime, avoiding the cameras and leaving the highway."

"But there is no reason to go to such great lengths just to kill Akikawa Sousuke and Akikawa Ryoko, two people who have no ability to resist."

Masumi Sera muttered to himself, then opened Google's satellite map.

After she found the national highway where the accident occurred on the satellite map, she began to zoom in and move the map forward little by little along the route.

After dragging for about ten kilometers, Masumi Sera suddenly discovered that there was a section of the route where there was no dividing strip between the forward and reverse lanes.

“We can turn around here!”

Sera Masumi said.

Upon hearing this, Yumi Miyamoto looked over and then an expression of surprise appeared on her face.

"Oh yeah, this is an opening to allow emergency vehicles to turn around in the event of an accident."

"If it's a motorcycle, it can turn around even during peak traffic hours."

Sera Masumi nodded, then switched the view back to the entrance.

"We thought the other party would definitely go out from other exits, so we ignored the motorcycle leaving from the opposite lane of the entrance."

"A motorcycle can't just disappear out of thin air. Since there's no trace of this motorcycle at any other exit, it's very likely that she turned around and left from the same place she came in."

As Sera Masumi said this, he rechecked the surveillance at the entrance.

After nearly an hour of careful investigation, Masumi Sera found the familiar figure in the surveillance video at 9:34 p.m.

"Sure enough, she turned around and went back."

The license plate number on the other party's motorcycle was also blocked, but the place name and pseudonym on it were revealed.

【Hakone Town】

Although Masumi Sera was unable to see the complete license plate of the motorcycle, a very happy expression appeared on her face.

License plates in small places in Japan usually consist of place name + kana + numbers.

The place name represents the place where the vehicle is registered, while the pseudonym is random.

But it is impossible for 【わ】 to be a random pseudonym on a license plate.

Because this is a pseudonym that is only used for rental vehicles.

"That is, this person rented this motorcycle in Hakone."

Hakone is not very big, and there are very few shops that rent motorcycles.

Masumi Sera searched online and found that there were only two shops in the whole of Hakone that could rent motorcycles.

The Metropolitan Police Department had been unable to identify the last motorcyclist for a long time, but Masumi Sera got the clue in just over three hours.

"Thank you, Sister Miyamoto."

Sera Masumi stood up excitedly and walked straight to the door.

"Hey, wait, where are you going, Sister Sera?"

Yumi Miyamoto shouted at Masumi Sera.

At this moment, Sera Masumi had already opened the door. She leaned back halfway and smiled at Miyamoto Yumi:
"Hakone."
