A smile flashed across Wang Hao's lips, and he looked at the ventilation duct and said: "This ventilation duct is 0 cm long and 40 cm wide. Let alone an adult, even children will have difficulty passing through here. And
As far as I know, the pipe connected to the room is not the narrowest section, and there is a passage that must be passed through, which is only 0x0 wide."
After hearing Wang Hao's words, Yan Hua and others felt their hearts sinking. It seems that their previous guess was wrong. So the question is, how did the murderer do it and appear in room 608 without anyone noticing?
Then he killed Xu Wen unknowingly and then left quietly.
If this problem is not resolved, there may be no way to continue investigating the case.
When Tan Yunduo heard Wang Hao's words, he was also quite disappointed. He had discussed so many suspicious points before, but he didn't expect that it would be of no use at all in the end.
This couldn't help but make her a little anxious, knowing that Yang Wei was still locked up.
but.
Just when Tan Yunduo was anxious, something suddenly happened in her heart. She looked at Wang Hao and blinked, a trace of doubt flashing in her beautiful eyes.
Although Tan Yunduo has some problems with her case-handling ability, she has one advantage, that is, she has a woman's intuition.
Now her intuition told her that there was something wrong with what Wang Hao said, but she couldn't figure out what the problem was.
Seeing that there were no useful clues, Yan Hua felt a little disappointed and said, "Manager Wang, I'm sorry to bother you this time. We're going back first. If anything happens, let us know as soon as possible."
Tan Yunduo frowned and thought for a while, but still couldn't figure it out. When this man heard that he was about to leave, he had an anxious look on his face and hurriedly shouted: "Wait a minute."
Everyone else immediately looked at Tan Yunduo.
Yan Hua asked doubtfully: "Yunduo, what else is going on?"
No matter how strong Tan Yunduo was, he would not be able to express doubts about Wang Hao in front of him. He opened his mouth and said, "Well, I, I think we should take a closer look."
Yan Hua couldn't laugh or cry, and said: "Yunduo, I know you want to help Yang Wei clear her name, but this place has already been searched. No matter how much the search continues, it will be of no avail."
When Tan Yunduo heard this, she knew that Yan Hua was right, but she had a feeling that there was indeed something wrong with what Wang Hao said just now, just when she didn't know how to explain it.
The worker who dismantled the ventilation duct removed a filter from the ventilation duct, looked at it a few times, and muttered: "Why is it so clean?
This thing must have been cleaned just once a few months ago."
Others had no reaction when they heard his words.
A flash of inspiration flashed in Tan Yunduo's mind, his beautiful eyes lit up, and he said excitedly: "This is it!"
Yan Hua was startled: "What's wrong?"
Tan Yunduo did not reply, but asked the worker: "Master, you just said that the ventilation ducts here have not been cleaned for several months?"
When the master saw the policeman asking him, he didn't dare to neglect, nodded and said: "Yes, the ventilator in this room was broken last time. I came over to fix it, because this is the only place on this floor that was broken. I remember it very clearly.
, it should have been 6 months ago.”
Tan Yunduo's eyes lit up, and he pointed to the filter in his hand and asked: "Six months, it should have been gathering dust for such a long time, right?"
The master nodded and affirmed: "That's for sure. The quality of this kind of filter is very good. It won't take 6 months, but it will be a little dusty in more than a month. But I don't know if there is something wrong with the ventilator here.
, there’s actually no dust accumulation at all, but I just checked and there’s nothing wrong with the ventilator.”
"Oops."
When Wang Hao heard this, his heart sank. He glanced at the master with a gloomy look, but he could not say anything more at this time, otherwise it would arouse the suspicion of Yan Hua and the others.
At this time, he thought that his performance was still perfect, but he did not expect that he had aroused the suspicion of Yan Hua and others long ago.
Obviously, Wang Hao's wish will come true.
Even he could tell there was a problem, let alone Yan Hua and the others.
Now even without Tan Yunduo saying anything, several people have already heard the problem.
Yan Hua's eyes lit up, and he immediately said: "Jia Ming, check the situation inside the ventilation duct."
He Jiaming was a little excited. This was a big discovery, and if he hadn't asked to see the ventilation duct, he wouldn't have discovered this problem. He couldn't wait for a long time. When he heard Yan Hua's words, he immediately responded,
Then I climbed up the ladder brought by the master, put my head in and started to check. However, because the light was too dark to see clearly, I had to take out my mobile phone to take a closer look.
It didn't matter. After looking at it, he said excitedly: "Captain, there are traces of dust in the passage."
Yan Hua perked up: "Very good! Don't destroy the scene, take a video first."
He Jiaming hurriedly turned on the camera and started recording. Then he took a few more photos, got down from the top, grabbed his phone and said, "Look."
Everyone hurriedly looked at the phone and saw the situation in the ventilation duct appeared on He Jiaming's phone. From the video, it could be seen that there was an obvious layer of dust in the channel, and on top of the dust.
, there are some very conspicuous drag marks! Li Hao took a few glances and quickly confirmed: "I'm sure these are definitely crawling marks. They were left by crawling when our police team was training on the sand.
That’s what the traces are.”
Wang Yang said in disbelief: "But... this passage is too small, can people crawl in it?
Could this be something left by some animal, such as a mouse?"
Li Hao hesitated for a moment and said, "It's not possible, but how big does this rat have to be to fill the entire passage?"
"Definitely not an animal!"
After watching the video, Yan Hua did not hesitate and immediately asked Wang Hao: "Manager Wang, I need the ventilation duct design drawings of your hotel."
An imperceptible gloom flashed deep in Wang Hao's eyes, but he quickly nodded and said, "Okay, I'll get it for you now."
Not long after, Wang Hao brought over the drawings of the ventilation duct.
Yan Hua grabbed it and looked at it for a few times. Just seeing the complicated lines on it gave him a headache. They were not professionals and could not understand it even if they looked carefully. However, he did not intend to look at it himself, but asked He Jiaming to
He took the photo and sent it back to the city bureau, who asked the city bureau to find an expert. He took out his cell phone and reported to Ye Qiu.
