Just as Fang Yu was trying to figure out Wu Linyu's words, an idea suddenly appeared in his mind.
Although the accuracy of the police's positioning equipment was much higher than the ordinary software on the phone.
However, due to his habit of using it, most of the time, he only cared about the level of the skill.
In other words, people were used to 2D planes instead of 3D.
Of course, this was also due to the fact that the screen was always in a 2D plane.
For example, if you wanted to go to a mall to find someone, you would have to go to the mall.
This person sent you his location, and you went to find him according to the route planned by the mobile navigation.
When you reached the first floor of the mall, the navigation software would prompt you that you were near the location.
However, when you turned 360 degrees and couldn't find the person, you didn't know that the person was right above you, on the second floor.。
This kind of problem was very easy to ignore.
Because the software shows that your location and the location of the person you are looking for have already overlapped.
However, this kind of overlap was only in the horizontal direction. It did not take into account the height in the vertical direction.
This was also the reason why Guan Yunfeng had been wondering where the kidnappers were.
That was why Qin Ya, Xiao Tong, and the others thought that this was a ghost report, and that Wu Linyu thought that the kidnappers could fly.
The kidnappers were not ghosts and could not fly. As for Room 401 downstairs, no one had entered it.
Because the kidnapper had been in Room 601 upstairs when he reported the case!
This kidnapper had a high criminal IQ.
He understood it very well and cleverly made use of the habitual thinking of humans.
He reported the case to 601, but said that he lived in 401.
In this way, as long as they found that the cell phone signal source was on the same vertical line between Room 401 and Room 601, they would mistakenly think that the kidnapper's words were true and that he was really in Room 401.
There was another important point. Even if the police noticed the vertical height when they were locating the location, they would not be able to do so.
However, because the height of the fourth floor and the sixth floor was about 12 meters and 16 meters respectively, the difference was not big and would eventually be ignored.
After all, the kidnapper at that time was just an ordinary reporter, Mr. Li. No one would suspect too much.
This was also why Fang Yu had told Guan Yunfeng that the cell phone's vertical height was about 16 meters.
Guan Yunfeng was confused when he first found out that Fang Yu wanted to check the height of the source of the phone signal.
However, when Fang Yu explained his reasoning, Guan Yunfeng, including Zhang Qiang and the others who were present at the time, all had doubts on their faces.
This reasoning sounded reasonable.
When they usually did positioning, they rarely considered the vertical height of the positioning point.
Moreover, if Fang Yu's reasoning was used, many things could be explained.
However, this reasoning had a fatal flaw.
That was that this deduction was too bold.
This boldness did not mean that Fang Yu's deduction was too wild and unrestrained, nor did it mean that Fang Yu's ideas were bold.
It was just that this kidnapper was too bold.
Placing himself so close to the police was like walking on a tightrope.
It was like a mouse fighting with a cat for food. If he was not careful, his life would be in danger.
If the kidnappers really did this, not to mention Zhang Qiang, even Guan Yunfeng would give them a thumbs up.
Not for anything else, but for this courage.
Guan Yunfeng had his doubts about Fang Yu's words, but he wasn't sure if he could deny it.
Therefore, after hanging up on Fang Yu, he got someone to start analyzing the location information again.
While Guan Yunfeng was organizing people to analyze the location information, Fang Yu was not idle either.
He brought Wu Linyu and Qin Ya to Huayuan Estate again.
Fang Yu wanted to know more about the owner of Room 601.
As Fang Yu expected, Room 601 had not been occupied for so many years.
According to the original landlord of Room 601, he had rented the house to a young man three years ago.
However, this young man was very strange at that time. He paid five years 'rent in one go.
However, in the past three years, he had not lived in the house many times.
The landlord had only seen this person when he rented the house and had never seen him again.
He heard the landlord say that the house was rented three years ago, and the kidnapper, who was pretending to be Mr. Li, died in a car accident three years ago.
This was definitely not a coincidence.
Fang Yu secretly concluded that his deduction was not wrong. There was a high probability that this kidnapper was as he thought.
She had reported the case from Room 601 and lied that she was staying in Room 401.
And this young man should be the kidnapper.
However, Fang Yu did not care much about the rental contract provided by the landlord.
This was obviously a premeditated kidnapping.
Therefore, the identity information on this contract that could expose his identity was definitely fake and had no reference value.
This time, because they could find the original landlord, they did not need to find the locksmith to enter Room 601.
When Fang Yu took the keys and walked to Room 601, Guan Yunfeng called.
"Fang Yu, you're really something!”
"We neglected it previously!"
"The person who impersonated Mr. Li reported the case. At that time, the location of his phone was the vertical high ground you said, 16.3 meters!”
"Room 601, there's definitely something wrong!”
Guan Yunfeng's tone was filled with excitement.
