After Qian Feng said these words that had been in his heart for a long time, he felt much better. After about a minute, Qian Feng said again: "Classmates, I am thirty years old this year, not a few years older than you."
, of course, he is younger than this classmate Sheng Qingfeng, and we are considered the same age.
To be honest, I always feel like I don’t have enough time and there’s so much more I can do.
Today, I am very happy to see you sitting here in class.
I believe that knowledge should be disseminated so that knowledge can play a greater and more important role, benefiting society and benefiting the people.
I really envy you and want to have the opportunity to learn knowledge just like you.
I sincerely ask students to cherish learning opportunities in the limited time, work hard to learn various skills, and apply what they have learned.
Finally, I still want to apologize for delaying my classmates’ class time by saying something off-topic because of my excitement. Please don’t take it offence!”
After saying that, he bowed deeply to Xie Liuyun and others to express his apology. When he straightened up and saw everyone smiling at him with understanding, he said happily: "Now, let's continue the class.
.”
As he spoke, he continued to analyze the first photo, "Look carefully at the trauma on the mouse's head. Based on the depression and edge marks of the trauma, we can more accurately determine the shape and size of the murder weapon."
At this time, Shang Baifeng raised his hand to signal Qian Feng that he had something to say.
Qian Feng immediately stopped his explanation and asked, "Classmate Shang, do you have any questions?"
"Instructor, will there be no error in judging the murder weapon based on the wound condition?"
"In a specific situation, it is biased to use this method to determine what kind of weapon the deceased was killed with. But in most cases, the weapon is determined based on the trauma of the wound. After practice, the result is
It’s accurate.”
"Instructor, what kind of situation are you talking about?"
"Under four circumstances, it is impossible to intuitively determine the murder weapon based on the injuries to the body, specifically rot, soaking and fire. There is another circumstance, please think about it?"
"destroy."
Huang Hanhan looked at Qian Feng and said these two words calmly without any hesitation.
Qian Feng nodded, "The answer that Classmate Huang said is correct, it is destruction."
Then, he said meaningfully: "Why did I stop after talking about the first three situations? It was to let the students distinguish them from the last situation.
Although in these four cases, the human body's muscle tissue will be severely deformed, causing the wound to be damaged due to swelling and displacement, it is not qualified as evidence.
However, whether the body is dumped in an inaccessible remote mountain forest or an abandoned house and allowed to rot into bones, or the body is buried in rivers and lakes to accelerate the decay, or the body is burned directly to cover up the fact of the murder, it is still considered a normal occurrence.
things within the scope.
Only destruction is different, and it is also the most extreme act of covering up the facts of a crime.
In the process of solving the case in the future, if we find that the body has been damaged, no matter what the degree of damage, we can directly conclude that the murderer is extremely cruel and has a seriously distorted psychology. We must pay great attention to it.
Because such criminals are extremely dangerous and possess strong psychological quality and anti-reconnaissance capabilities.
When encountering such a case, you must explain the key points to your colleagues, explain the matters to be paid attention to, closely investigate the people related to the deceased, and do not let go of any suspicious persons.
The more inconspicuous the person, the more likely he is to dare to commit a crime.
The less likely a person is to commit a crime, the more likely he is to be the murderer.
Remember, when investigating a case, 'what you see may not necessarily be true', and 'what you hear may not be true'. When investigating a person, you must check the background, and when you ask people, you must verify the time, and the truth will eventually surface."
Qian Feng's words caused everyone to fall into deep thought. He is indeed an experienced forensic expert!
Xie Liuyun felt that Qian Feng's professional level and analytical ability could make him a detective.
Sheng Qingfeng also felt the same. When he was in Xi'an before, due to work reasons, he assisted the police in analyzing the psychological activities of some criminals, which provided a lot of help to the police in solving the case.
Among them, what left a deep impression on him was that most of the suspects who committed crimes with brutal methods had stable psychological qualities, strong psychological defenses, and would not easily reveal their true colors.
In order to break the vigilance of these criminal suspects, he had in-depth exchanges with the police officers, detectives, forensic doctors and witnesses who handled the case, and developed targeted questionnaires for these criminal suspects, which played a very good role in the interrogation.
.
All suspects who concealed the truth were eventually questioned and confessed to their criminal behavior.
The reason why his questionnaire has achieved such good results is first of all because he studies people's psychology and the questions on the questionnaire are very professionally designed.
Secondly, it must be attributed to his prior understanding of the basic facts of the case. The forensic autopsy report and feedback from the crime scene were of great help to him in formulating the questionnaire.
It is true that a good forensic doctor can take over half of the detective team.
With his thoughts in mind, Sheng Qingfeng couldn't help but turn his head and cast his gaze at Huang Hanhan, who was sitting diagonally behind him, looking at the handsome and beautiful girl in front of him.
"Hanyan Guard" is the perfect candidate for their team's military doctor and forensic doctor. The burden on this little girl is not light!
As the eldest person in the team, he is not only a comrade-in-arms with her, but she is also about the same age as his own child. As a matter of fact, he should pay more attention to and take care of her in the future.
Next, Qian Feng explained the next four photos in order.
As the answers to the mystery were solved one by one, Xie Liuyun and the others knew that their judgments on the cause of death of the white mouse were accurate.
This can also be understood why Qian Feng had such emotional fluctuations before.
He was excited by the intelligence of the students he wanted to teach, which made him feel that he had four more excellent crime busters, and he was sincerely happy from the bottom of his heart.
This joy has now also infected Xie Liuyun and others. They feel that the passion to achieve something in their hearts that was ignited by Yong Ming has become even stronger.
After finishing the lecture on the last photo, Qian Feng began to pack away his teaching materials and personal belongings on the desk.
Xie Liuyun asked: "Instructor, have you finished your teaching today?"
Qian Feng raised his head and said, "Yes! Why didn't you hear enough?"
Xie Liuyun and others said in unison: "Yes!"
Huang Hanhan smiled and said: "When I was listening with great enthusiasm, it was time to finish. I always felt that there was something unfinished."
