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

Upon hearing this, Li Jian suddenly turned around and abruptly retracted the foot he had already lifted.

He had pondered this unsolved case countless times in his heart.

When the case occurred, he followed up on the entire investigation. In the later special operations organized by the bureau to tackle unsolved homicide cases, he devoted himself wholeheartedly and made use of his years of accumulated criminal investigation experience.

He conducted a comprehensive and thorough study from multiple perspectives, including the examination of traces at the crime scene, the identification of the suspect, the motive for the crime, and the trajectory of related physical evidence.

However, the case remained unsolved, with no breakthrough conclusions.

Regarding Jiang Chen's analysis of the possibility of a crime of passion, they had considered it in their initial investigation, but the results of several detailed investigations were not satisfactory.

At least through a comprehensive investigation of the emotional relationships and social interactions of the two deceased, no suspicious persons with emotional entanglements were found.

Therefore, after multiple collective discussions and assessments, their task force finally determined that the motive for the crime was revenge killing, and all subsequent investigations continued to advance along this core line of reasoning.

At this moment, suddenly having to overturn the original conclusion and completely reverse the overall nature of the case, Li Jian smiled calmly and said, "Brother Jiang Chen, we have discussed the nature of this case repeatedly in the team in the early stages. Regarding the possibility of a crime of passion that you mentioned, we have also organized police forces to conduct a thorough investigation, but in the end, there was still no effective progress. Therefore, I think it is really unnecessary to spend more energy to study this direction of investigation in depth."

As soon as he finished speaking, Wang Hui quickly stepped forward and said, "Captain Li, we've already determined that there's a possibility of homicide in the case. Although we've narrowed down the nature of the case, after repeated verifications and investigations, we still haven't found any key clues. Do you think we should re-examine the case from the overlooked angle of a crime of passion?"

Zhang Yan also said, "Just now, I listened to Brother Jiang Chen's analysis of the logic and reasoning process behind the crime of passion. His reasons were very convincing and completely plausible. Don't you think so?"

"Although I'm not a professional criminal investigator, I watch quite a few criminal investigation TV dramas and read quite a few criminal investigation books on a regular basis. I personally think that Junior Brother Jiang Chen's analysis is indeed very reasonable."

Seeing the two people beside him speak one after another, Li Jian mentally reviewed the three points of analysis that Jiang Chen had just made.

The main reason their task force ruled out the possibility of a crime of passion was that they were unable to identify any individuals suspected of committing the crime.

Criminal investigations always emphasize the core motive for a crime, which is usually one of three things: a crime of passion, a revenge killing, or a crime of passion.

Of course, there is also a very low probability situation, which is that mentally ill people commit crimes indiscriminately.

However, such cases are extremely rare in actual cases.

At this moment, Li Jian recalled Jiang Chen's analysis and suddenly felt that it was completely different from his previous thinking.

Their previous investigative logic was to first deduce that it might be a crime of passion, then investigate along this direction one by one, and only after failing to find the corresponding suspect did they reverse the logic and conclude that it was a revenge killing.

The initial approach to solving the case was like answering a multiple-choice question: first, eliminate options A and B, and finally narrow down the answer to C and D.

Option D, which assumes the murder was committed by a mentally ill person, is incorrect because there are no mentally abnormal individuals in the vicinity of the crime scene. Therefore, option C, which suggests a revenge killing, becomes the most likely conclusion.

However, Jiang Chen's analysis just now directly deduced the final conclusion from the crime scene and detailed evidence.

It was the same multiple-choice question for solving a case, but they used the traditional process of elimination.

Jiang Chen, however, treated the multiple-choice question as a short-answer question, relying directly on evidence to accurately pinpoint the answer from all possibilities. The two have fundamentally different investigative approaches.

In an instant, Li Jian looked at Jiang Chen with a serious expression, repeatedly considering the accuracy of the conclusion in his mind.

If Jiang Chen were just a new recruit, he would most likely have laughed off such a bold conclusion and not taken it to heart.

Jiang Chen has recently solved two difficult murder cases, and the key breakthroughs in both cases were all due to Jiang Chen's meticulous observation and accurate reasoning.

Under these circumstances, Jiang Chen's analytical conclusions had to be seriously considered by him.

After a moment's thought, Li Jian turned to the crowd and said, "Since Brother Jiang Chen has just thoroughly analyzed this case and personally reviewed the crime scene records and autopsy report, it is enough to show that your thinking is meticulous and comprehensive."

"In that case, we will gather all the key officers who were involved in solving the case in the conference room in half an hour to re-examine the case."

"Jiang Chen, you should carefully organize your views and evidence, and our whole team will discuss and exchange ideas. If what you said is indeed reasonable and well-founded, then we will officially reopen this cold case and launch a full investigation again."

Upon hearing this, Jiang Chen quickly nodded and replied, "Okay, Captain Li, I'll go back right away to organize my thoughts and get ready."

At this moment, Wang Hui's face was full of surprise, and he was secretly astonished.

Is this long-standing case being reopened so easily?

Isn't this decision-making process too fast?

Li Jian saw through his thoughts, smiled and waved his hand, saying, "Hey, we're all on the same team. It's normal for us to sit together and discuss cases. It's nothing special."

"Furthermore, Brother Jiang Chen has solved two murder cases in a row, so he must be bursting with ideas right now. We can take this opportunity to witness his brainstorming session, which might just bring a new breakthrough to this murder case."

After speaking, Li Jian turned to look at Jiang Chen and continued:

"Now that it's settled, I'll immediately have the office clerk notify the other officers that we'll meet in the conference room in 30 minutes. At that time, you can systematically and completely explain all your points."

After giving his instructions, Li Jian turned and quickly left.

Although he had just made the decision to reopen the case in public, he did not express his opinion directly. He neither completely denied Jiang Chen's reasoning nor immediately affirmed his analytical conclusions.

After all, this case was the result of repeated analysis by several senior police officers in the early stages, and the final conclusion was reached after joint efforts by criminal investigation departments at the provincial, municipal, and county levels.

He couldn't find a direct reason to refute Jiang Chen's analysis, but it was by no means easy to accept and overturn the previous official conclusion.

Let alone him, the captain of a criminal investigation team, even Director Ma of the bureau would not dare to easily make a decision to change the conclusion reached by the three-level joint action.

Watching Li Jian's figure disappear into the entrance of the criminal investigation building, Wang Hui turned around and patted Jiang Chen on the shoulder, saying with an amazed look, "Brother Jiang Chen, you are really amazing. With just a meticulous analysis, you managed to reopen the investigation of this long-standing cold case."

Jiang Chen smiled calmly and said, "This is just the beginning. Later in the conference room, you'll see me give a long speech, explaining all the reasons behind my reasoning."

"I have a much more complete analytical approach that I haven't shared yet. What I just mentioned was merely an appetizer. The real core reasoning is yet to come."
