Chapter 1557 (1/2)
”I know this,” Zeng Ke immediately adjusted the video to a certain frame after hearing Wu Xiumin's analysis, ”you see, this is the shadow of the light shining on the criminal from behind, here... Here...”
Pointing to the less obvious shadow on the ground, he said: ”video experts have found that the shadow on the ground has protrusions and deformation, which shows that the killer should be wearing some kind of wide hat or mask!”
”Another mask!” Zhao Yu repeated a sentence and couldn't help thinking of Han Kuan in the devil case.
”It seems...” Wu Xiumin said, ”it's difficult to uncover the mystery by video alone. More detailed evidence is needed to prove that Kang Ziqing is the murderer!”
”It seems... I can only go to Xijiang in person!” Zhao Yu raised her head and said to Wu Xiumin, ”sister Wu, you can book a ticket now. Let's go to BeiCang!
”Zeng Ke,” he told Zeng Ke again, ”you and ran Tao stay in Fengping and continue to investigate all the evidence, especially the murder video, to see what useful clues can be found?”
”Oh, OK!” Yes.
”Since BeiCang may be the starting point of the video murder,” Zhao Yu looked out of the window and said decisively, ”let's go to BeiCang - look for the truth!!!”
……
At ten o'clock in the evening, only Zhao Yu was left in the office of the special investigation team.
Since the plane is scheduled for tomorrow morning, he is still at his desk, continuing to analyze the information of the video murder.
Through a long detective career, Zhao Yu has formed his own case handling style. When dealing with the case, he needs to update at any time, master all the case information at any time, and can't leave every detail behind.
Due to the large number of victims, the complexity of video homicide is no less than the five outstanding cases. The data collected every day is based on folders. Zhao Yu needs to look through all the data in each folder.
Moreover, in the process of viewing, Zhao Yu can't be perfunctory. Important clues are often hidden in these seemingly ordinary materials. He needs to think carefully and peel off the cocoon. He can't be careless at all.
However, since the experience of the devil case, Zhao Yu has long been comfortable with this cumbersome copywriting work.
Moreover, he found that he could calm down and think of something he hadn't noticed before only when he quietly checked the data.
At the moment, his thick notebook is almost full of half a book, on which all the doubts about the video homicide or the investigation ideas are recorded.
Zhao Yu used serial numbers to list more than 80 items one by one, such as:
1. In 2003, why did the murderer stop killing in 2003 and 2004 for nearly two years because the murderer himself had an accident? Or because the killer had an accident during the murder?
Or did he not stop killing at all, but the video tape was missing?
2. Murder weapon: through video identification, the murderer used a 30 cm long dagger. The blade should be made of stainless steel and wooden handle. From the appearance, it has certain characteristics of military dagger, and it is suspected that it is self-made. No similar knives were found in the market.
Through comparison, in the eleven videos, the shape of the murder weapon has not changed, and it is likely to be the same
3. Sound: the sound recording function is enabled in the video, which can hear the groans, wind, leaves, etc. of the victim, but the voice of the murderer himself is not captured.
The murderer didn't say a word from beginning to end. I don't know whether it was because of his character or deliberately planted the blame
……
5. It is found from Kang Ziqing's only video record that when Kang Ziqing took the goods from others, he was greeted by his left hand. He suspected that he was left-handed. The murderer killed with a knife in his right hand
Supplementary information: through the inquiry of Li Mo and other parties, it has been confirmed that Kang Ziqing is not left-handed
……
7. Camera problem: I ignored a problem before. The 11 murder videos recorded by the murderer were all from the same model of camera. If Kang Ziqing took advantage of his position to steal the camera of the crew, how could he catch up with the same model or the same camera every time?
It has been confirmed that the company has never lost the camera, or even purchased the camera of this model at all.
Therefore, the camera either belongs to the murderer himself or the murderer steals what others do, which has nothing to do with the film and television company.
Supplementary information: according to the survey, although this model of camera has been sold in China, the sales volume is not large because of its high price.
If tracing channels, can potential suspects be found?
