Unique soot! 【2】

“Okay, I have other things to do. I can rest assured that this case is handed over to you.”
Dong Guohua said to Hao Wei, “Remember what I told you.”
“You can rest assured, old director, and promise to live up to your mission!”
Hao Wei waved at Dong Guohua and said, “Old Director, walk slowly…”
On the other side, after Li Ze carefully inspected the house on site, he asked the investigating police officer on the side, “Has the investigation clear the details of this house?”
These police officers under Hao Wei are already very familiar with Li Ze. They are very aware of how awesome this young man in his early twenties is. Even their own captain has to respectfully call him teacher, so they naturally dare not neglect him.
“It’s been investigated, Mr. Li.”
that nameThe police officer said: “The owner of this building is named ‘Yang Chao’, a local from our port city. He knows the old captain and was the first to call the police.”
“So, he is the first witness?”
Li Ze raised his eyebrows and said, “What about others?”
“Taking notes at our police station.”
The police officer replied respectfully.
“Bring him to me.”
Li Ze ordered.
Hao Wei had told them more than once in private that any request from Li Ze must be obeyed unconditionally, so the policeman did not hesitate too much, and nodded in agreement, “Understood!”
“Mr. Li, we found some photos in the old captain’s pocket!”
said a surveyor.
Li Ze hurriedly came to the vicinity of the corpse, and the investigating policeman immediately handed the photo in his hand to Li Ze.
Taking the photos, Li Ze flipped through the photos one by one.
The clarity of the photo is not high, and the light inside is also a little dim. Li Ze immediately judged that this was a screenshot from some surveillance cameras.
Li Ze squinted and carefully observed this set of photos. From the content, the photos were taken in a certain street. The time was at night. There were people coming and going in the street, and several cars were parked on the side of the road.
There are a total of six photos in this group. Li Ze has carefully browsed through each photo, but the content inside is mostly the same.
Similar streets, about the same time, the same surveillance screenshots, and the vast sea of ​​people in the screenshots.
What exactly are these photos trying to convey?
Why did Jiang Bin take these photos?
Li Ze frowned and pondered, but the information he had at the moment was too little, and he couldn’t figure it out for a while.
The police officers on the side also lowered their heads and followed Li Ze to observe the group of photos, one of the police officers suddenly seemed to remember something, and shouted in surprise: “I remembered, this is not near the previous case. the street?”
After his clarification, the other police officers also looked suddenly enlightened.
“Yes, this is a screenshot of the street surveillance near the previous two murders!”
“Yeah, we’ve all been to these streets before, right in the area of ​​Hong Kong Polytechnic University!”
“What is the old captain doing with the screenshots of the street surveillance over there? Are there any important clues in these photos?”
……
The streets near the first two cases?
The streets near the first two cases?
Li Ze frowned slightly, “Has the deceased been to the crime scene of the two previous murderers?”
A young police officer said quickly: “Yes! Last time I followed the three teams to the scene to do the final forensics work, the old captain just happened to come. At that time, I was still curious about who he was, and how he entered the scene and no one rushed. he’s going out…”
“What did he do on the scene?”
Li Ze asked.
“He didn’t do anything… He just looked around at the scene, as if he was looking for something.”
The young police officer said while recalling: “But in the end he did seem to find something… I think it should be… soot?”
“Soot?”
Li Ze’s eyes lit up, “Have you collected evidence for preservation?”
“I asked this question at the time, and other senior police officers said that it was none of our business and we didn’t need to save it.”
The policeman scratched his head and said a little embarrassedly, “But I always felt that I might need it in the future, so I secretly kept some samples…”
“well done.”
Li Ze asked, “What’s your name?”
“Ding Wei.”
The policeman replied.
“Your idea is correct, but any clues and details that may be related to the case must be paid attention to, especially the physical evidence, which must be preserved.”
Li Ze said: “Maybe you can’t see the role of these details in front of you. Once some opportunity comes, these details will become important clues when you notice them!”
“Understood!”
The policeman named Ding Wei looked a little excited. Li Ze’s words were undoubtedly a compliment to him and the greatest affirmation of his actions.
“Where’s the ash you kept? Did you bring it?”
Li Ze asked.
“Bring it.”
Ding Wei immediately took out a transparent evidence bag from his body, which contained a pinch of soot, “I was afraid that the material evidence department would not accept it, so I kept it with me all the time…”
Li Ze took the evidence bag, carefully took out the pinch of soot with tweezers, and observed it carefully.
“This is not the ashes of ordinary cigarettes.”
Li Ze immediately made a judgment, “From the perspective of the shape and quality of the soot, this should be the soot formed by special homemade cigarettes, and the shredded tobacco inside is also extraordinary, not directly available in the ordinary market, and it should be added by myself. All kinds of homemade spice and essence.”
“Mr. Li, do you have such a deep understanding of cigarettes?”
Ding Wei said with a look of admiration, “I don’t think you usually smoke much?”
“Not smoking doesn’t mean not doing research.”
Li Ze chuckled, “You must know that among the criminals, a large proportion of people like to smoke. After all, smoking can relieve their nervousness and is the best tool to pass the time. Some criminals deliberately use their hands to smoke. Squeeze out cigarettes to burn fingerprints.”
“Therefore, as a criminal investigator, although you are not required to be omniscient, you must be familiar with various things or tools that criminals may come into contact with.. ”
