Chapter 807 Important Clues, Gradually Leading to the Case
After identifying key suspects, the Criminal Investigation Detachment quickly brought all kinds of physical evidence collected at the scene back to the police station's technical analysis room, thus launching a technical battle against time. Qin Chuan knew that this physical evidence was key to uncovering the truth of the case, and every detail could become a breakthrough in solving the case. He took charge and directed the work in an orderly manner, his eyes revealing an undeniable firmness and determination.
"How's the trace evidence analysis going?" Qin Chuan walked into the trace evidence analysis room, his steps steady, his sharp gaze landing on the technicians busy at the microscope. At this moment, although he was anxious, his years of criminal investigation experience kept him calm, knowing that in such a situation, any haste could affect his judgment.
Li, who was in charge of trace evidence analysis, looked up, his eyes behind his glasses focused intently. "Chief, we're analyzing the footprints and fingerprints collected from the scene. Some of the footprints are blurry, but through special enhancement technology, we've discovered a set of footprints with a very unique sole pattern. Our initial assessment is that it's a limited-edition sneaker. These shoes are extremely rare in Dongchuan City, making them very valuable for investigation." As he spoke, Li pointed to the image under the microscope, his tone revealing a hint of excitement at discovering a crucial clue.
Qin Chuan nodded slightly, quickly sorting through various possibilities in his mind. After a moment of thought, he said, "Immediately compile a list of people who have purchased this shoe, focusing on those who have had contact with the suspect. Time is of the essence; every clue could determine the direction of the case." His instructions were concise and to the point. Years of experience in criminal investigation allowed him to quickly grasp the key points, pointing the investigation in the right direction and making the entire investigation instantly clear.
Meanwhile, the surveillance investigation team was also working intensively. Dongchuan City's surveillance network was vast and complex; finding useful clues in a massive amount of surveillance video was like finding a needle in a haystack. But Qin Chuan firmly believed that the murderer must have left clues before and after committing the crime, and that with patience and meticulousness, they would surely find a breakthrough.
"How's the surveillance footage investigation going?" Qin Chuan asked as he entered the surveillance analysis room, looking at the constantly flashing surveillance images on the screen. At that moment, he was also silently praying that they could find the key clues as soon as possible and end this battle with the murderer.
Xiao Wang, who was in charge of the surveillance investigation, frowned, his face showing some fatigue and frustration: "Chief, there are many surveillance cameras around the crime scene, and we have checked most of them, but we haven't found any suspicious persons yet." Xiao Wang's voice revealed a hint of helplessness, and his eyes were bloodshot from staring at the screen for a long time.
Qin Chuan stared at the surveillance footage, his gaze sharp as an eagle: "Expand the scope of the investigation. We need to focus not only on the area surrounding the crime scene, but also on surveillance footage near the suspect's residence and workplace. The perpetrator may have exhibited unusual behavior before and after the crime. We cannot overlook any possible clue, even the slightest anomaly." Under his command, the surveillance investigation team quickly adjusted their focus and threw themselves back into the intense work. Everyone was inspired by Qin Chuan's determination and decisiveness, and their fighting spirit was rekindled.
Inside the forensic analysis lab, DNA testing was underway on the note found at the scene and the saliva residue on the teacup. Technician Xiao Zhang rushed to Qin Chuan with the test report, his steps hurried, his face beaming with excitement at having discovered a crucial clue.
"Chief, after comparing the handwriting on the note, although there was no direct match with the suspect, by analyzing the writing habits and font characteristics, we found that it has certain similarities with Zhao Gang's usual writing style. Moreover, the DNA test results of the saliva residue on the teacup show that, in addition to the deceased Wang Qiang, there is another unknown DNA that is very likely to belong to the murderer." When Xiao Zhang reported, his tone was filled with barely concealed excitement. The emergence of these clues gave new hope for solving the case.
Qin Chuan's eyes lit up, a surge of joy welling up inside him, but he quickly suppressed his emotions and remained calm: "Enter this unknown DNA into the database for comparison. At the same time, intensify the investigation into Zhao Gang, starting with his daily behavior and social circle, to find more clues related to the case. We must strike while the iron is hot and not give the murderer any chance to breathe."
Under Qin Chuan's command, the various teams within the Criminal Investigation Detachment collaborated closely, significantly improving their work efficiency. The trace evidence identification team quickly compiled a list of individuals who purchased the limited-edition sneakers. After investigation, they discovered that one person who had business dealings with Zhao Gang had been behaving suspiciously recently. The surveillance investigation team, after expanding their search, also discovered that Zhao Gang had appeared in an alley not far from the crime scene on the afternoon of the incident, behaving highly suspiciously.
"Summon Zhao Gang immediately and collect more evidence. Make sure everything is foolproof. Remember, we must ensure that every piece of evidence can withstand scrutiny and leaves the murderer with no room for argument." Qin Chuan decisively issued the order. He knew that at this critical moment, every decision was crucial, and any small mistake could cause setbacks in the case investigation.
Inside the interrogation room, Zhao Gang continued to deny his crimes when questioned by the police. He sat in the interrogation chair, his eyes darting around, his hands unconsciously rubbing together, and fine beads of sweat appearing on his forehead, but he still tried to appear calm.
“Zhao Gang, we are all aware of your business conflict with Wang Qiang. On the day of the incident, you left the company midway through the day, and your whereabouts are a mystery. All the clues at the scene point to you.” Qin Chuan entered the interrogation room, his gaze fixed on Zhao Gang. His voice was firm and powerful, like a sharp sword piercing Zhao Gang's defenses. At this moment, his heart was filled with a determination to uncover the truth and uphold justice; he was determined to bring the murderer to justice.
Sweat beaded on Zhao Gang's forehead, and his hands trembled involuntarily, but he still made a last-ditch effort: "I... I was just meeting a client, I didn't kill anyone. You must have made a mistake." His voice began to tremble, and a hint of panic flashed in his eyes, but he still tried to cover up his crime.
"Then why did you deliberately conceal your whereabouts after the crime? The footprints at the scene, the handwriting on the note that resembles yours, and the CCTV footage of you appearing near the crime scene—how do you explain all of this?" Qin Chuan pressed on relentlessly, each question like a cannonball striking Zhao Gang's weak points. He stared intently into Zhao Gang's eyes, not missing a single subtle change in his expression, using his powerful aura and rigorous logic to make Zhao Gang feel the majesty and inviolability of the law.
Faced with overwhelming evidence, Zhao Gang's mental defenses crumbled completely. He slumped into a chair, clutching his head, and confessed to his crime. It turned out that he had meticulously planned the murder because he was dissatisfied with Wang Qiang's handling of company decisions and profit distribution. He had secretly added sleeping pills to Wang Qiang's drink, and after Wang Qiang lost his ability to resist, he killed him with a pre-prepared knife. He then cleaned up the scene in an attempt to cover up his crime.
