I walked to the living room unconvinced, sat down on the sofa, crossed my hands on my chest, glared at Brother Ming and said, "Why did you send me out to study without my consent?"
"The People's Police Force is a disciplinary force, you know what I want to say!" Brother Ming put his hands in his pockets and stared at me.
"You use this to pressure me again - obey the orders of your superiors." I curled my lips and replied.
"It's good to know. Do you think you don't need to study? Do you think you performed well in this case?" Brother Ming stood in front of me and pointed at me and asked.
"What? You don't expect me to solve the case?" I impatiently stretched out my hand and knocked aside his hand pointing at me.
"There are many coincidental factors involved in the detection of this case. Do you think there will be so many coincidences in future cases?" Brother Ming took his hand back and asked.
I didn¡¯t say anything when he asked me this, because what he said was indeed an objective situation.
Brother Ming took out a cigarette from his pocket, lit it, took a deep breath, and asked:
"Do you know how many mistakes you made in this case?"
"Mistake? Trace science was not used in the entire case. What mistake do you think I made?" I asked somewhat unconvinced.
Brother Ming shook his head with a slight disappointment, stared at me and said: "As a trace inspector, you should always think about where there will be traces. According to Xie Wenle's account at that time, when he dumped the body He didn¡¯t wear gloves at all, and the body was dumped against the guardrail. His fingerprints are very likely to be left on the guardrail. Have you, the so-called trace inspector, handled the guardrail?"
?????????????????????????????????. Hearing this, I felt a chill in my heart. Brother Ming was right. This was indeed a relatively big oversight.
"I didn't handle it, why didn't you remind me then? Come back now!" I retorted angrily.
"Although I am a forensic doctor, I know that fingerprints cannot be processed on this guardrail." Brother Ming said this again suddenly.
"It's impossible. It's clearly written in our textbooks. Fingerprints will be left as long as they are touched. Moreover, the guardrails on the highway are painted. This kind of smooth object is the easiest to leave fingerprints. Do you understand? ?¡± I sat on the sofa and began to ¡°teach¡± Brother Ming a lesson.
"Yes, you are right, then tell me, what is the basis for fingerprint comparison?" Brother Ming did not refute, but instead asked me to test.
No matter how good I am at cooking, I still know these basic things, so I got up from the sofa, walked around the coffee table and said, "The so-called fingerprints are small lines, so how do you identify a suspect through fingerprints?" What? In fact, they all rely on some detailed features on the fingerprint, such as short sticks, small dots, bifurcations, etc. These features are very small and cannot be distinguished by ordinary people's eyes. A professional fingerprint examiner must enlarge the photo of the fingerprint several times to do so. Carry out comparison work. Generally, ten to fourteen characteristic points are found, which can basically be used to identify the person."
"Well, you are very specific, and you know it yourself. We believe that fingerprints are looking for some small characteristic points on the lines, but the specific situation needs to be treated in detail. The guardrails on the highway are not cleaned all year round, and the floating dust layer is the largest. The thickness can reach one to two millimeters. When a person's palm touches the guardrail, the first thing that sticks to the guardrail is the floating dust. At this time, the gaps in the suspect's fingerprints have been filled with floating dust, and the lines have been covered with dust. If there are layers of coverage, why do you expect to leave identifiable fingerprints on the guardrail?" Brother Ming stared at me blankly, waiting for my answer.
When he said that, I, who was so proud just now, immediately turned into a wilted cucumber. I calmed down a little, and shouted to him in great annoyance: "Do you feel happy playing with me like this? You know everything, and you still come to ask me?"
"If you are a qualified trace examiner, I, the forensic doctor, should be speechless today!" Brother Ming said the word "forensic doctor" and emphasized his tone.
I drooped my head and sat back on the sofa feebly.
At this time, Brother Ming walked up to me with a cigarette in his hand, looked down at me and said:
"Also, as a trace examiner, you can't just focus on handprints and footprints. Some traces of tool tools may also be the key to solving the case. Take this case as an example. The suspect used a cutting machine to decompose the body. If you follow the normal Procedure, as a trace examiner, you also need to issue an inspection report on the cutting marks to prove that the cross-sectional marks at the fractured bone of the deceased were caused by the cutting machine. But can you do it now?"
"I"When he said this, I was speechless.
Brother Ming took a puff of cigarette, exhaled the smoke and continued:
"There have been quite a few cases of murder with guns in the past two years. If bullet casings and bullets are found at the crime scene, the traces on them are the key to finalizing the case. In the event of a gun case, an inspection report of such traces must be issued. You can hide You can¡¯t hide, but as far as I know, your understanding of bullet marks is zero, and you still think you don¡¯t need to learn?¡±
After Brother Ming finished speaking, he stood in front of me and smoked cigarettes one after another, waiting for my answer. He waited until he finished smoking a cigarette, and I didn't say a word.
Squeak, Brother Ming pressed the cigarette butt hard into the ashtray on the coffee table, took out an envelope from his pocket, threw it on the coffee table, and said to me: "This is the four thousand yuan reward from the corpse case branch. Sunday , get up and go to Huashan." After saying that, he walked towards his father's bedroom.
On the third day, I was forced to drag my suitcase on this study trip. After wandering around on the bus for five hours, I finally arrived at the destination of this trip - Huashan City.
Huashan City is located in the southernmost part of Wannan Province and is the most famous tourist area in Wannan Province. The entire Huashan City is surrounded by mountains and has beautiful scenery. There is the unforgettable "Lovers Valley" and the majestic and steepest peak in the world.
As soon as the bus entered Huashan City, we saw the bustling cityscape on both sides of the highway, with magnificently decorated hotels and restaurants. As the business card of Wannan Province, Huashan City can be said to be ahead of other cities in everything.
I dragged my suitcase out of the station, and saw a middle-aged man in his 50s holding a sign and looking around. He was wearing a gray shirt and a pair of police uniform trousers, and he had a kind face. I recognized at a glance that this was the teacher introduced to me by Brother Ming, my father¡¯s junior fellow student, Li Feng, who is known as the number one person in the field of trace inspection in Wannan Province.
"Teacher Li Feng." I walked up to the man with my head hanging down.
"Are you Senior Brother's son, Leng Qiming's subordinate, Si Yuanlong?" Li Feng looked me up and down and asked.
"Yes, hello, Teacher Li Feng." I took a deep breath and politely extended my right hand.
"Hello!" Teacher Li Feng also extended his right hand very politely.
Although I was very reluctant to come to this place, I was very adaptable to the ways of the world. Based on the mentality of "taking it as it comes, take care of it", I adjusted myself in the shortest possible time.
Teacher Li Feng looked at my expression, grinned, and said with a smile: "I think you are much more sensible than your father said."
"Thank you for the compliment, teacher. I will cause you trouble this month." I smiled back.
"No trouble, no trouble. Let's go, we have to hurry up, otherwise we may not be able to make it in time for dinner." As he said that, he picked up the suitcase next to me and walked towards the parking lot in front.
I raised my right hand and looked at my watch in confusion. Isn¡¯t it only ten o¡¯clock in the morning? How could I be late for dinner?
The next nearly six hours of rugged mountain roads completely dispelled my doubts. I thought that Teacher Li Feng's workplace was in the urban area, and I was planning to have a good time in the urban area, but now it's better, this car is going straight to the mountain col.
"Xiaolong, we're here, get out of the car." Teacher Li Feng parked the car in the courtyard of a four-story building with elegant architecture.
As soon as I got out of the car, "Huashan City Qianshan County Criminal Science and Technology Laboratory" appeared in front of me.
"Teacher Li Feng, these four floors are all technical rooms?" I asked with some surprise.
"Yes." Teacher Li Feng cheerfully opened the trunk and took out my luggage.
"My dear, you are so elegant. The conditions are much better than where we are." I stood outside the door and looked up at 125 degrees, sighing.
Teacher Li Feng stepped forward and patted me on the shoulder, smiled and said to me: "This is assigned by the previous director."
"It seems that the leadership's attention is different!" I replied a little jealously.
"Whether the leader takes it seriously depends on whether we have the ability, don't you think?" Teacher Li Feng turned around and said with a smile.
"Well, that makes sense." I seemed to hear the implication in his words.
"By the way, how many people are there in our technical room?" I asked, changing the subject.
Teacher Li Feng turned to me and said with a somewhat low tone:
"Currently, there are two, one for forensics and one for me. We have just recruited a few this year, and they are still training in the city. It is estimated that there will be no time every year when they are unable to work."
"What? There are only two technicians in such a big office building?" I looked at him in surprise.
"It's the same across the country. There is a huge shortage of technicians! Excellent technicians are more valuable than giant pandas." Teacher Li Feng said to me meaningfully.
"Then Teacher Li Feng, aren't you responsible for traces, inspections, and photography?" I quickly interrupted.
"It used to be, and now I have to be in charge of forensic medicine for two months. Our only forensic doctor here has been transferred to other places to work on cases." Teacher Li Feng spread his hands and said cheerfully.
"I'm dizzy! I bet you are a polished commander" (Remember this website address: www.hlnovel.com)said to me.
