Wang Xun asked, "What do you mean?"
Guan Feng simply selected a few clips he had watched and explained them.
"Due to the privacy of the victims, I will not show you the specific video. In short, everyone should pay attention to the clues in the investigation. Keep an eye on Huang Youwen and don't let the three victims go. They all have motives for the crime."
Li Xiangdong said, "Team leader, I was just about to say that. This is a clue we found yesterday."
I handed over a few photos.
Guan Feng took it, glanced at it, and exclaimed in surprise, "Li Lan?"
Li Xiangdong nodded and said, "That's right! We found it in the surveillance footage at the first intersection before the residential area."
Guan Feng asked, "Is it not in the elevator?"
Li Xiangdong handed over two more photos.
"Team leader, look! These two photos were found in the elevator. The person came down from the 14th floor, wearing a hat, mask, and sunglasses, and even a sun-protective jacket. But look at the shoes, and compare them with this one!"
Guan Feng only glanced at them before confirming that the shoes matched.
He said, "The shoes alone are not enough to determine that they are the same person. However, everyone's walking posture is unique, and it is almost impossible for two people to walk exactly the same way. Do you have a video?"
Li Xiangdong chuckled and said, "That's exactly what we were looking for, team leader, to help with the footprint identification."
Bring the computer.
Pointing to the two videos above, he said, "These are videos we obtained from the property management and the monitoring center, respectively. Team leader, please take a look."
Guan Feng took it and began to examine it carefully.
The stride, posture, and arm swing of both when walking...
Every detail was compared and verified.
Ten minutes later.
The two figures gradually overlapped.
Guan Feng put down the tablet and nodded, saying, "We can confirm that they are the same person!"
Li Xiangdong immediately clapped his hands and said, "Great! We have already contacted Huang Youwen and confirmed that he did not meet with Li Lan at home yesterday afternoon. In other words, Li Lan went to Huang Youwen's house without permission!"
Guan Feng frowned and said, "Judging from this, Li Lan is highly suspicious!"
Li Xiangdong said, "That's right! Team leader, should we proceed with the arrest?"
Guan Feng shook his head and said, "Let's not alert them yet. Is there any news from the technical department? What are the results of the voiceprint analysis?"
As they were talking.
"Squeak!"
The office door opened.
Chen Xuewen walked in, pushing up his glasses.
Guan Feng laughed, "Speak of the devil! Captain Chen, what's the result?"
Chen Xuewen nodded and said, "The phone recording has been processed. Although the other party used a voice changer, some voiceprint characteristics were still identified, but they can only be used to assist in the judgment and cannot be used as evidence!"
Guan Feng asked, "Can we only confirm that it's a woman?"
Chen Xuewen said, "That's right!"
Guan Feng's expression changed slightly.
The result was worse than he had expected.
But since she is a woman...
The suspicion surrounding Li Lan and the other two women has increased further.
At this moment, Chen Xuewen handed over another test report and explained, "After extracting the key, no fingerprints were found, which means the suspect must have deliberately wiped it. However, we were able to extract mugwort fiber, plant oil and other components from it."
Huang Lili asked curiously, "What do you mean?"
Guan Feng said, "This is inkpad."
Chen Xuewen pushed up his glasses and nodded, saying, "I didn't expect Team Leader Guan to know this too! That's right, this is a common ingredient in ink pads. Key imprints usually use this kind of ink pad, and because of the presence of plant oil, it's difficult to clean it completely in one go, which is why we were able to detect it."
Guan Feng said, "We should also thank the suspect for this oversight!"
He paused, then looked around at the group and said:
"The evidence now clearly shows that the suspect most likely obtained the key to Huang Youwen's safe through rubbing techniques and stole related valuables and USB drives. Although it cannot be directly determined at present that Li Lan is the thief!"
"But! There's a very high chance she made a copy of the key!"
"Li Xiangdong, go to the monitoring center and retrieve all traces of Li Lan after she left, especially the places where she stayed for a long time. Compare them one by one and see if you can find anything!"
"Wang Xun, contact the team members who are staying at Huang Youwen's house, keep a close eye on Huang Youwen, and prevent the suspect from calling again!"
"Huang Lili, retrieve Li Lan's identity information and get it ready..."
