The Forensic Doctor Better Than a Detective

Chapter 853 - 448: Giving a Lecture to Criminal Investigation Colleagues Across the Province! (Part 2)

"This time, we specially invited you to share your valuable practical experience with criminal investigation colleagues across the province.""Thousands of criminal police are waiting online for your live class, so please share generously!"

"Certainly."

Jiang An solemnly nodded, "Criminal investigation really doesn’t have any exclusive secrets; it’s merely about thinking more thoroughly about each case-handling step, and executing each investigation procedure more meticulously."

"Since we’re giving a talk, it’s critical that everyone learns something real."

At 9:30, Director Hou personally hosted this province-wide specialty seminar on solving homicide cases.

Before the video system officially connected, he gently tapped the microphone to test it, and said, "Brothers and sisters on the criminal investigation front line across the province, good morning."

"Now let’s officially begin the meeting."

"This meeting is held in a video conference format, although our cities are far apart and cover extensive areas, it’s precisely this modern meeting method that allows us to gather in the shortest time, ensuring both work efficiency and comprehensive coverage."

"Solving homicide cases has always been a crucial aspect of our province’s criminal investigation efforts."

"As the saying goes, ’the public watches the police, mainly focusing on solving cases,’ and this sentiment reveals the public’s most basic expectation of law enforcement agencies."

"How to enhance case-solving capabilities and improve case-solving efficiency has always been the central point on our criminal investigation task list."

"Among all cases, homicides, due to their unique nature and significant impact, are the fortress we must conquer."

"In practice, solving some homicide cases often requires substantial human and material resources, lengthy investigation cycles, and great difficulty in work; improper handling can affect the credibility of law enforcement and even trigger petitions affecting social harmony and stability."

"Because of this, the department leadership has prioritized homicide case-solving unprecedentedly, organizing this homicide-solving experience-sharing event."

At this point, Director Hou turned to look at Jiang An sitting beside him, his eyes full of admiration.

"Today, we are very honored to invite a highly representative practical expert as our main speaker, Captain Jiang An from the Jiangcheng Criminal Investigation Team."

"Jiangcheng Criminal Investigation Team has always maintained a leading position in the first tier of our province’s criminal investigation forces."

"Especially in recent years, Jiangcheng’s solve rate has consistently topped the province’s charts with a significant lead over second place by more than ten percentage points."

"In this sense, Jiangcheng has indeed developed a mature, effective working method for solving homicide cases."

"Whether it’s rapidly solving current homicides or tackling historical cold cases, Jiangcheng has delivered impressive results."

"Captain Jiang An, as the leading figure of Jiangcheng Criminal Investigation, is recognized as a case-solving expert on our criminal investigation front."

"He led his team to solve hundreds of difficult and complex cases, including historical cases spanning several years with missing crucial evidence, showcasing outstanding professional skills and problem-solving abilities."

"Therefore, today we are fortunate to have Captain Jiang An present on site, bringing us a valuable session of experience-sharing."

"Alright, I won’t take up more of your precious time."

"Next, let’s welcome Captain Jiang An with warm applause to share his practical insights and reflections from the frontline of solving homicide cases!"

Two minutes later, Jiang An walked onto the podium and opened the PPT.

The first slide simply displayed the words "Insights and Reflections on Solving Homicide Cases."

He chose this straightforward title out of consistent modesty—after all, it’s his first time standing on the provincial stage, and he hopes to engage in exchanges with a pragmatic and low-profile attitude.

He gently tapped the microphone to test it, then turned to the audience, saying, "Esteemed leaders, colleagues, Director Hou’s introduction has truly honored me beyond my merit."

"Although Jiangcheng Criminal Investigation has made some progress in recent years and accumulated certain experience in solving some cases, to be honest, our solve rate has not yet reached the ideal state of 100%."

"Especially in terms of homicide case-solving, we still face some tough ’bones to crack,’ with quite a few weak points that urgently require breakthroughs."

"The road is still long, the responsibilities on our shoulders remain significant, and we must continue working hard and overcoming challenges."

He paused slightly, glanced sideways at the title on the screen, and said, "Today’s report is titled ’Insights and Reflections on Solving Homicide Cases.’"

"These insights mainly come from practice summaries and reflections during multiple homicide investigations by the Jiangcheng Criminal Investigation Team in recent years."

"Therefore, in the upcoming exchange, I earnestly hope to hear your valuable opinions, critiques, and corrections."

"If anyone has different views or better suggestions, feel free to bring them up; we can delve into a more in-depth discussion after the meeting."

"Next, I will briefly report some rudimentary insights from Jiangcheng’s homicide case-solving to all leaders and colleagues present, hoping to serve as a catalyst for further discussion."

Then, the PPT switched to a new page, clearly listing the main content of today’s lecture.

"Regarding the fundamental concepts and definitions of homicides, I believe everyone is already quite familiar, so we won’t delve into them excessively here."

"Today, we focus directly on the specific steps in the case-solving process."

"I believe the successful solving of a homicide case usually hinges on seven key steps: first is the alarm reception process, second is scene investigation, third is body examination, fourth is field investigation, fifth is analysis assessment, sixth is interrogation breakthrough, and seventh is evidence securing and case-solving retrospective."

"These seven aspects are interconnected, indispensable, forming the basic framework and logical chain for solving homicide cases."

"Next, I will detail each of these seven steps."

"First, let’s discuss the alarm reception process."

"Perhaps to many, alarm reception is merely the police station receiving reports from citizens, then dispatching officers to the scene, seemingly just a procedural beginning."

"But precisely this seemingly simple step often plays a decisive role in the subsequent progress of a case."

"Because it directly relates to the speed and quality of initiating scene protection work."

"In criminal investigations, especially homicide cases, the scene is the treasure trove of evidence, the starting point for uncovering the truth."

"We often say, case breakthroughs, especially entering mid to late stages, often rely on forming a complete and rigorous objective evidence chain."

"For historical cold cases, lacking solid material evidence, investigation work becomes nearly impossible."

"Therefore, effective early-stage scene protection is the foundation of the entire investigation, and crucial to whether we can seize the initiative."

"Speaking of scene protection, Jiangcheng law enforcement agencies have long adhered to the ’Three Ones’ principle."

"First, strictly prevent unrelated personnel from entering the scene. Whether they’re curious onlookers or unnecessary police officers, they must be strictly controlled outside the police line to minimize human interference."

"Second, personnel who must enter the scene—such as medical staff for emergency care, firefighters for rescues, or investigators for initial assessments—must be fully prepared with protection before entrance and meticulously document personal information, entry and exit times, and reasons, ensuring traceability."

"Third, if the scene is damaged due to an emergency or force majeure, fixed recording through photographs, videos, etc., must be done instantly, preserving as much original state information as possible."

"In practice, we require local police officers to activate law enforcement recorders upon arrival at the scene to continuously record the scene overview, entrances and exits, key traces, especially those traces and material evidence prone to damage or disappearance, such as footprints, fingerprints, biological marks, should be focusedly documented."

"Even when encountering situations like insufficient battery or equipment failure with law enforcement recorders, flexible usage of tools like mobile phones to capture and fix evidence should be done, never citing equipment issues as an excuse to omit crucial evidence. This is crucial for effective scene evidence preservation and reflects responsibility implementation to individuals."

"Alright, regarding alarm reception and scene protection, we’ve addressed these aspects. Moving into the second aspect—scene investigation."
