Looking at the two young detectives in front of her, Sato Miwako directly questioned the screening method proposed by them.
"Although we can check the passes we get at the highway entrance as evidence, there are now dedicated ETC lanes on the highway."
Miwako Sato reminded them, "In this kind of passage, you can pass through directly without paying manually, so there's no need for a pass."
What Miwako Sato was talking about was the new technology on the highway. The so-called "etc" is an electronic non-stop toll collection system, which is basically used for charging tolls on bridges or highways.
The specific application of this technology is to install an induction card on the vehicle windshield to conduct dedicated short-range communication with the microwave antenna on the lane of the toll station etc.
After that, computer networking technology is used to conduct back-end settlement processing with the bank. In this way, there is no need to stop the car specifically to pay manually. The highway tolls can be automatically deducted from the card more quickly, thus realizing automatic charging.
Compared with manual processing, this type of charging only takes about 2 seconds, which is 5 to 10 times more efficient than manual channels.
Although there are some reasons such as complicated procedures that make promotion difficult, it must be said that this is an advanced technology.
Returning to the case, if the two people in the factory followed their screening method, there would indeed be loopholes in the ETC dedicated channel.
"At least now we can confirm that the deceased entered the highway through the same entrance as us."
Hattori Heiji smiled and said, "Unfortunately, the ETC machine there has been malfunctioning since this morning.
So you can only use the manual channel that issues passes."
"I see!"
Gao Mu's expression brightened: "This way, the hidden danger of the ETC channel is eliminated. All that remains is to lock down the person who only has the entrance pass."
"And after we checked the pass held by the messenger, we found that the messenger had actually entered the highway an hour earlier than us!" Kudo Shinichi said his discovery.
"One hour!?" Sato Miwako asked in surprise, "So..."
"I guess they stopped at a rest stop to eat something." Hattori Heiji explained the reason for the one-hour delay.
"That is to say, the murderer did not simply enter the highway from the same entrance at the same time."
Kudo Shinichi raised the corner of his mouth, a confident smile on his face, as if he had locked onto his prey. "And the three cars we've locked onto are the ones that were still driving near the deceased an hour after he entered the highway!"
"So that's how it is." Sato Miwako suddenly realized and was also a little impressed.
"Okay, now that we know the screening method, let's get down to business."
Tang Ze said, "Detective Maori is waiting for the forensic personnel about a kilometer away. Let's take advantage of this time to meet the three suspects."
Tang Ze was not surprised at all that the two of them were able to narrow down the suspects to three people so quickly.
Although to those who are not in the know, it would be a headache to screen out the suspect from hundreds of cars.
But if you know the known information that the two people have, this screening method is actually not difficult to think of.
Sato Miwako and the others only felt that this method was unreliable because of the errors in the intelligence.
But if they knew that the ETC channel at the highway intersection where the deceased entered was broken, and that the deceased had entered the highway again an hour ago, they would naturally choose the same screening method as Kudo and others.
In any case, according to scientific laws, a large number of suspects will be instantly narrowed down to 3 to 5 people due to various specific conditions.
This may seem very "scientific" at first glance, but in fact it also follows certain scientific laws.
Just like what Hattori Heiji said before, it's not like he uses super powers to kill people, so naturally there will be traces left.
As long as the deceased's information is extracted, those who do not meet the requirements can be naturally screened out and the qualified suspects can be locked in.
Take this case for example, perhaps some people will meet a condition, such as entering the highway from the same toll booth at the same time, or eating at the same rest stop.
But this is most likely a coincidence, but if both conditions are met, the suspicion will naturally increase.
After screening, the only ones left are the three people in front of you.
The first is Mizobata Riko, who has pink hair and is obviously related to the deceased Gunpeira.
According to Riko Mizobata, she and the deceased were in a boyfriend-girlfriend relationship and they took the highway just to go for a ride together.
"You said taking a ride? But you were driving alone, right?" Takagi was recording the other party's confession while looking at the other party's yellow Mitsubishi modified car with a rear wing.
"That's right. Our driving habits are different from others," Mizobata Riko said. "Jun Ping and I are used to driving our own cars. Is that okay?"
"Then was it planned in advance with Mr. Junping that you and Mr. Junping would rest in the rest stop?" Tang Ze asked.
"No, it was Junping who said he suddenly felt very sleepy and wanted to rest for an hour. I was bored so I had to kill time in the restaurant at the rest stop and then wake him up at a certain time." Mizobata Riko shook her head and explained.
Upon hearing this, Tang Ze and everyone else looked at each other and became more confident about the previous screening.
If what Mizobata Riko said was true, then because Mr. Junping changed his mind at the last minute, the criminal naturally had no choice but to follow him, which naturally increased the suspicion of the other two people.
