Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

The conditions for investigating this case are actually quite 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 is basically under surveillance with no blind spots.

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 monitoring room to investigate the relevant surveillance.

If the person who jumped from the building committed suicide, then the surveillance camera should be able to capture that person's figure, and no one else should appear at the same time.

After everyone went up one floor, they found a long-closed security door. Lu Chuan 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 then came out.

"No one should touch the doorknob. I'll have the detective come over and collect fingerprints from it."

Wang Zhaokai nodded: "I'll arrange it right away."

Wang Zhaokai also noticed this detail. If the person who just jumped to his death committed suicide, then he should have pushed the door open by himself, and her fingerprints should be left on the security door.

After everyone arrived at the rooftop and looked around, they found that, as Manager Ye had said, the rooftop was not very wide and was filled with blowers and central air conditioning.

Looking around, there are many buildings around that are taller than the buildings in the distance, so the view from above is not very good and you can't see very far.

In addition, the central air conditioning and blower were running, and the buzzing noise on the roof was quite loud.

"All of you stay here, Zhao Kai, follow me."

The property staff and several criminal police were standing at the door and did not go over. If this case was not an accident, then the rooftop was also an important scene.

At this time, Lu Chuan had habitually put on foot covers and white gloves, and then walked towards the direction where the deceased fell.

There is a circle of anti-fall net made of iron wire on the edge of the building, but the height is not very high, but it can still provide a certain degree of protection.

"Director Lu, here!"

Wang Zhaokai pointed to the front right and saw a high-heeled shoe left on the ground.

"There is a high-heeled shoe here, and there are obvious signs of climbing on the wire mesh 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 victim's body at the crime scene below and had indeed seen a high-heeled shoe at the scene.

At that time, he was still wondering if the other high-heeled shoe was lost.

"It's the deceased's."

The deceased's high heels were found on the rooftop, which proves that the deceased did jump from this location.

Lu Chuan came to the edge of the building and looked down. Just below him was the body of the deceased and the police were busy working. From this position he could see everything that was happening below.

The building in the distance is not an irregular structure, but a straight up and down structure, so after the four of them jumped from here, they reached the ground directly.

"What do you think?"

Lu Chuan looked around and suddenly asked. Wang Zhaokai was also observing the surrounding situation. From the current scene, there was actually nothing suspicious.

"There is a wire fence at the edge of the rooftop to prevent falling. If the person wanted to jump over, he would definitely come into contact with the wire fence, leaving a shoe here. In fact, I think there should be nothing special about this situation. The deceased fell down after climbing over the wire fence."

There were no leftover items around.

There was only one high-heeled shoe on the ground.

There was indeed nothing suspicious about Lu Chuan's presence at the scene, but Lu Chuan was staring at a puddle of water next to his high heels in a daze.

"Two questions. Where is the cell phone of the first deceased? If he is an employee working in this building, then of course he is most likely an employee working inside the building. When we came in from the lobby just now, Yuanfang Building has an access control system. If you don't work here, you need to register for the visitor channel manually to come in."

"I just checked the body of the deceased downstairs and didn't find any mobile phone fragments. It is very likely that the person didn't have a mobile phone with him when he jumped from the building."

"We didn't find any cell phones on the rooftop either."

There are indeed some problems with this. Considering the degree of dependence of modern people on mobile phones, even if the other person commits suicide, the mobile phone should be kept with him.

Of course, it is also possible that Lu Chuan was overthinking it. If the other party left the phone in the office, or had already had thoughts of suicide, it is possible that he put the phone at home.

"There are indeed some problems with this. We need to investigate now and confirm the other party's identity before we can look for relevant clues and see if we can find the other party's phone."

Wang Zhaokai said.

If you can't find your phone now, just spend some time looking for it.

"The second question that puzzles me is where did this puddle of water come from?"

Lu Chuan squatted in the water next to his high heels, looking a little dazed.

When Lu Chuan discovered the high-heeled shoe just after he reached the rooftop, he noticed the water stain next to the high-heeled shoe.

It wasn't raining, so there was no possibility of water accumulation on the roof.

When Lu Chuan came up, he looked at several central air-conditioning external units nearby. Although the central air-conditioning external units might produce moisture, it was not directly discharged onto the roof. Instead, there were special water diversion holes that allowed the moisture to flow away directly.

"Is it possible that the deceased drank water before jumping off the building? Or maybe he vomited after gargling his mouth?"

Wang Zhaokai looked around and said.

Lu Chuan shook his head: "Of course this is possible, but is it very likely?"

"There is another question. If the deceased drank water before jumping off the building, what did he use? Did he drink from a mineral water bottle? If he used a mineral water bottle to check, then where is the level? When I was investigating downstairs just now, I did not find any empty mineral water bottles near the wetland."

Wang Zhaokai frowned.

As an experienced criminal policeman, Wang Chaokai has experienced many accidental death cases over the years. In fact, when dealing with any seemingly accidental death case, the police will treat it very cautiously.

In addition to some traffic accidents, the focus is on some fires and some falling cases, which are the focus of investigation by the police.

Any detail that does not conform to common sense may attract the attention of the police and may also lead to major changes in the nature of these cases. (End of this chapter)
