The conditions for investigating this case are actually relatively good. There are many surveillance cameras in the Yuanfang Financial Building. When Lu Chuan entered the building just now, he found four or five cameras in the lobby. The entire lobby basically has no blind spots. Under surveillance.
Therefore, with so many surveillance cameras, it is easy to find out the entire movement trajectory of the person who jumped from the building.
People from Xingfuli Police Station have been arranged to go to the surveillance room to investigate related surveillance.
If the person who jumped from the building committed suicide, then the surveillance should be able to capture the other person's figure, and at the same time, no one else should appear.
After everyone went up to the first floor, there was indeed a long-closed security door. They put on gloves and pushed open the security door.
During this process, he did not touch the door handle, but pressed the door lock on the door handle with his fingers, pushed it open, and came out.
"No one should touch this doorknob. Let the criminal police come over later to collect fingerprints on it."
Wang Zhaokai nodded: "I'll make arrangements right away."
Wang Zhaokai also noticed this detail. If the person who just jumped to death committed suicide, then he should have pushed it open alone, and her fingerprints should be left on the security door.
After everyone arrived at the rooftop, they looked around and found that, as Manager Ye said, the rooftop was not wide. It was all covered with blowers and central air conditioning.
Looking around, there are many buildings that are taller than the buildings in the distance, so the scenery above is not that good and you can't see very far.
In addition, the central air conditioner and blower are running, so the noise on the rooftop is quite loud.
"All of you, stay here, Zhaokai follow me."
The property management staff and several criminal police officers were standing at the door and did not go past. If this case was not an accident, then the rooftop would also be an important scene.
At this time, Lu Chuan had habitually put on his foot gloves and white gloves, and then walked towards the direction where the deceased fell.
There is a wire-stretched anti-fall net on the edge of the building, but it is not very high, but it can also play a certain protective role.
"Bureau Lu, here!"
Wang Zhaokai pointed to the front right, and there was a high-heeled shoe left on the ground.
"There is a high-heeled shoe here, and there are obvious signs of climbing on the barbed wire fence here. The deceased should have fallen from here."
Lu Chuan walked over and noticed the high-heeled shoe on the ground.
He had seen the body of the deceased at the crime scene below, and he did see a high-heeled shoe at the scene.
At that time, he was still wondering if the other high heel was lost.
"It belongs to the deceased."
The deceased's high heels were found on the rooftop, which proved that the deceased did jump from this position.
Lu Chuan came to the edge of the building and looked down. Just below was the body of the deceased. The police were also busy underneath. From this position, he could see everything going on below.
The distant building is not a special-shaped structure, it is straight up and down, so the four of them jumped directly to the ground.
"What do you think?"
Lu Chuan looked around and suddenly asked. Wang Zhaokai was also observing the surrounding situation just now. Judging from the current scene, there is actually nothing suspicious.
"There is an anti-falling barbed wire fence on the edge of the rooftop. If the opponent wants to jump over, he will definitely come into contact with the barbed wire, leaving a shoe here. In fact, I think there should be nothing special about this situation. The deceased After climbing over the barbed wire fence, he fell."
There are no leftover items around.
There was only one high heel on the ground.
There was indeed nothing suspicious about Lu Chuan's scene, but Lu Chuan was staring at the puddle of water next to the high heels in trance.
"Two questions, where is the mobile phone of the first deceased? If the other person is an employee working in this building, of course there is a high probability that he should be an employee working in the building. When we came in from the lobby just now, there was someone in the distant building. If the access control system does not work here, then you need to manually register the visitor channel to come in. ”
"I just observed the condition of the deceased's body when I was downstairs, and I didn't find any fragments of the mobile phone. I said that the other person probably didn't have his mobile phone with him when he jumped off the building."
"We didn't find any mobile phones on the rooftop upstairs."
There are indeed some problems with this. Judging from the degree of dependence of modern people on mobile phones, even if the other party commits suicide, the mobile phone should be taken with him.
Of course, it is also possible that Lu Chuan is overthinking it. If the other party left his phone in the office, or had long had suicidal thoughts, it is of course possible that he would leave his phone at home.
"There are indeed some problems with this. We need to check it now. Only after confirming the identity of the other party can we look for relevant clues and see if we can find the other party's mobile phone."

Wang Zhaokai said.
If you can’t find the mobile phone now, then take the time to look for it.
"The second question that puzzles me is where did this water stain come from?"
Lu Chuan squatted in the water next to his high heels, having been in a daze before.
Lu Chuan noticed the water stains next to the high heels when he first discovered the high heels on the rooftop.
It wasn't raining, so there was no possibility of water pooling on the rooftop.
When Lu Chuan came up, he looked at several central air-conditioning plug-in units nearby. Although the central air-conditioning plug-in units may produce moisture, they are not directly arranged on the rooftop. Instead, there are special water guide holes, and it flows away directly. .
"Is it possible that the deceased drank water before jumping off the building? Or rinsed his mouth and vomited?"
Wang Zhaokai looked around and said.
Lu Chuan shook his head: "Of course it is possible, but is it very likely?"
"In addition, there is another question. If the deceased drank water before jumping off the building, what did he drink from? Was it a mineral water bottle? Then. If the other party used a mineral water bottle to check, what is the level? When I was investigating downstairs, I didn’t find any empty mineral water bottles near the wetland.”
Wang Zhaokai frowned.
As a veteran detective, Wang Chaokai has experienced many accidental death cases over the years. In fact, the police treat any seemingly accidental death case very carefully.
In addition to some traffic accidents, the focus is on some fires, and the scenes of some falling cases are the focus of the police investigation.
Any detail that is not consistent with common sense may attract the attention of the police, and may also lead to major changes in the nature of these cases. (End of chapter)
