Forensic Doctor 2003: I Became a Legend on the Front Lines of Criminal Investigation

Suddenly, Jiang Chen's expression turned serious, and he fell silent.

"I hope you can answer this question truthfully."

Of course, if you can't answer the question or deliberately lie to conceal something, we have our own ways of verifying it.

We will definitely go to all the major psychiatric hospitals and various mental health departments in the province to retrieve your medical records and thoroughly investigate whether you have any relevant medical or hospitalization records in the past.

Upon hearing this, Qin Yu's expression suddenly stiffened, and he instantly fell silent.

After a long silence, he slowly raised his head. "I...I did have a hospital stay before. But what does that have to do with the case you're investigating?"

Jiang Chen replied coldly, "Whether it matters or not is not up to you or me to decide. Everything must be determined by the facts and evidence of the case."

After a brief hesitation, Jiang Chen didn't give him a chance to think or catch his breath, and continued to press, "When exactly did you see a doctor about mental illness? And what type of mental illness were you diagnosed with?"

Qin Yu instantly became agitated, and retorted in a defiant tone, "You're the one with a mental illness! I don't have any mental illness at all. I just sometimes can't control my emotions and behavior."

During the interrogation, Qin Yu added: "I remember it clearly. It was when I was working in an electronics factory two years ago that I suddenly lost consciousness and became unconscious one day. It was my coworkers who found me in time and rushed me to the hospital."

I was hospitalized for two whole months before I fully recovered and was discharged. If you don't believe me, just ask any of my colleagues at the factory; everyone there knows about it.

Hearing this, Jiang Chen said calmly, "We will verify these details one by one in person. Besides this hospitalization, have you had any other similar hospitalization experiences?"

"No, it only happened once in my life."

As soon as he finished speaking, Qin Yu suddenly frowned and asked, "I just don't understand, how does this old story, which is so many years old, have to do with your investigation?"

Moreover, I heard about this incident when he died in the accident, and the family's fate was indeed extremely tragic.

Instead of focusing on catching the real murderer, you keep interrogating me. What's the logic behind that?

As he spoke, Jiang Chen glanced at him sideways and said, "We police officers handle cases, it's not your place to give us pointers."

All you need to do is cooperate honestly and answer all our questions truthfully.

After saying that, Jiang Chen ignored his emotions and continued the interrogation, asking, "Do you live alone in your house now?"

"I live alone. My parents live separately. I work at the factory every day and only go home in the morning and evening."

At this moment, Zhang Yan, who was sitting aside and listening to the entire interrogation, was completely confused as she listened to Jiang Chen's precise and interconnected questions.

Compared to the basic anti-pornography and anti-illegal publications work I did in the security team, the entire process of handling cases and interrogating people in the criminal investigation team was far more exciting and complex than the grassroots security work.

This is essentially a high-intensity psychological tug-of-war and precise game between people.

Once her thoughts settled, Zhang Yan nodded silently, seemingly lost in thought.

After the interrogation ended, Jiang Chen said in a deep voice, "Let's go, the interrogation ends here for now."

Zhang Yan, filled with curiosity, couldn't help but ask, "Was the interrogation over so simply? What will happen to Qin Yu afterward?"

Before he could even voice his many unanswered questions, Jiang Chen had already led him out of the interrogation room.

At that moment, outside in the corridor, Li Jian and Wang Hui were leaning against the wall, chatting and puffing on their cigarettes.

Seeing Jiang Chen and Zhang Yan come out of the door, the two nodded to each other, looked up at them, and said, "It's getting late, let's grab something to eat first, and then we'll head back to Jiangcheng right away."

No sooner had he finished speaking than Jiang Chen suddenly interrupted everyone: "No! I think there's definitely something wrong with this Qin Yu. We have to dig deep into his background to find clues. We can't just let him go like this."

Upon hearing this, Li Jian turned to look at Wang Hui beside him, then turned to look at Jiang Chen, and then smiled and advised, "Brother, I know you are dedicated to solving cases."

But Qin Yu was just an ordinary factory worker, and he wasn't even near the scene of the crime at the time of the incident.

Moreover, we just confirmed the situation with the factory's human resources manager. He has worked at the factory for over ten years and is a true veteran employee.

Jiang Chen's expression was firm, and he immediately retorted, "Does working for many years mean that you have no connection with the case?"

This location is several hours' drive from the crime scene, seemingly leaving him no time to commit the crime, but who can guarantee he's not a suspect?

Jiang Chen then pressed on in a deep voice, "This case happened five years ago. Who can now give a 100% accurate account of Qin Yu's daily movements and work schedule five years ago? And who can definitively prove that Qin Yu was indeed working normally at the factory on the day of the incident?"

Upon being asked this question, Li Jian was instantly stunned. During his conversation with the HR manager, the manager had indeed praised Qin Yu for her diligence, calling her a long-serving and outstanding employee who had received numerous awards for excellence in the electronics factory.

However, when it comes to verifying the precise attendance records from the day of the incident five years ago, it is impossible to do so because the time was too long ago. In the early years, the factory still used paper sign-in records and did not keep any electronic attendance records.

Coming to his senses, Li Jian quickly said, "Even so, I still think you're being a bit subjective."

I know you are highly capable, that's something everyone knows. But in handling cases, personal subjective judgments cannot override the case investigation and evidence collection process.

Sometimes, excessive subjective assumptions can mislead the direction of the entire case investigation.

Take this case for example. During our initial investigation, no one expected the suspect to be in Dongcheng, hundreds of kilometers away from Jiangcheng, right?

Jiang Chen said with certainty and seriousness, "But the key point is that this Qin Yu has a history of intermittent mental illness."

Upon hearing this, Li Jian immediately raised an eyebrow: "Are you sure about this?"

"I'm 100% sure." Jiang Chen nodded in response. "I specifically questioned him during the interrogation just now, and he also had a mental breakdown at the factory last year. The factory had to send someone to take him to the hospital for treatment."

Wang Hui, standing nearby, asked doubtfully, "Even so, what can we do? His illness occurred last year, while the case happened five years ago. The two are completely unrelated."

Jiang Chen's eyes sharpened as he stated bluntly, "Is it possible that five years ago, during a mental breakdown, he impulsively committed the murder?"

Upon hearing this, Li Jian couldn't help but chuckle and shake his head. He had worked in criminal investigation for many years, dealing with all kinds of criminal cases year-round; fighting crime and solving cases was his primary job.

However, forcibly linking intermittent psychotic episodes with a long-distance murder case five years ago was beyond his scope of understanding in handling cases.

Since he started working in criminal investigation, he had never encountered such outrageous case speculation.

Wang Hui, who was standing to the side, smiled and advised, "Jiang Chen, I know you are eager to solve the case and want to make a contribution, but you can't rush things. There will be plenty of opportunities to solve cases in the future."

The team leader and I just spoke with the HR manager in detail. Qin Yu is a responsible, honest, and reliable person. He's always been down-to-earth and doesn't seem like the type to commit murder and flee. I simply can't believe he's a murderer.

Zhang Yan nodded in agreement, "Yes, he looked honest and unassuming to me just now. He didn't look like a vicious murderer at all."

Hearing everyone's words, Jiang Chen slowly said, "Senior sister, the words 'murderer' are never etched on their face."
