Chapter 21 thunder?Electricity?

The little pig looked very embarrassed: the clothes it was wrapped in were already muddy, and the little tail stretched out from the middle of the clothes ridiculously, forming a small circle. Impatiently, I drove it towards the sewage pit beside the asphalt road, humming dissatisfiedly, and suddenly something unexpected happened——as soon as its feet touched the sewage, it immediately jumped Come out, the sound that came out of the mouth also turned into a whine at this moment. The problem is that I am now a hundred times more embarrassed than the little pig. Although it is only a few hundred meters away from the prison, I have already spent more than two hours.

When the people in the institute suggested to me to put this little pig on a leash like a dog, I didn't like it!If passers-by regard it as my pet, where will I put my face!Now I regret it too much. This little pig who has never seen the world is scared to run around when he sees a car on the road. I have to admit that my physical flexibility is far from the same as when I was studying and playing basketball. That's right, I had to fly to save it several times to catch it who was screaming and screaming. The sad thing is that the little pig likes to escape to some garbage dump or muddy ground not long after the rain.

If you see me now, you will definitely not recognize me. My clothes, trousers and shoes are all muddy, and even my face is doomed. The high temperature on the asphalt road in summer quickly turns the mud into a mud shell, and then it is poisoned by the sun. As soon as the oil and sweat from the roasting washed away, my face looked as if I had just finished singing a Beijing opera, and it was so lively. In my left hand I hold a small bamboo stick for driving pigs, and in my right hand I hold a GPRS instrument: I am worried that the few falls just now have damaged this delicate thing, and its big painted face like mine also makes my heart ache , I was pulling my sleeves to wipe it clean!Injustice! !Why did you make me suffer so much!Things have to start from the beginning.

The bureau received a report early yesterday morning, saying that there was a young man who worked overtime at work and did not return overnight. His family members called him and he refused to answer the phone. The frightened family members searched everywhere in the early morning rain, and found him on the way home. , but at this time he can no longer breathe, and the motorcycle he rides to and from get off work every day is quietly placed beside him. According to the young man’s colleague, yesterday there was a contract for a batch of clothing bound for Europe in the factory that was about to expire, and all had to be shipped on the same day, so everyone in the factory worked overtime together until around one o’clock in the evening before returning home.

When I received the bad news early this morning, all the familiar friends were inexplicably surprised—the young man rode a motorcycle home alone yesterday, and before leaving, he joked with everyone, but no one noticed anything strange about him, how could he say it alone? Is it gone?I heard from colleagues that the young man is usually kind and kind. As the workshop director of the unit, he is very considerate. Yesterday, a worker accidentally injured his finger while rushing to work, and he personally accompanied him to the hospital. The boss is also very satisfied with the young man's work. Not only does he work hard in his usual work, but even this order was brought in by the young man by taking advantage of his familiarity with English.

He has been married for less than half a year at home, and he is not only a good husband to his wife, but also a good son to his parents. How can the family not cry into a pile of tears in such a situation?This is quite strange: if it is a vendetta, the young man has neither made any enemies nor heard of any financial disputes with others, so the vendetta would not be chosen on a main road; if it is a robbery Killing, there is no reason for the valuable motorcycles to be left at the scene, not to mention that the policeman in charge said that the young man had cash and bank cards in his wallet; love killing is even more unreliable, the young man has never had any sexual news, according to him The newlyweds' situation is also unlikely.

No matter how you think it is impossible, it is a fact that people are dead, and as a forensic doctor, you have to figure out what's going on. The investigation of the case did not bring us any useful information, so I had to bite the bullet and go to the scene, which I don't like very much. I always hope that the investigation of the case can give me some useful clues, and then provide me with a direction or several possibilities at the scene, and finally go to the corpse to confirm which idea is the most correct. Any step in these steps that fails to achieve the set goal means that the difficulty of the subsequent steps will increase.

The case took place on a wide road with a wide view of the surrounding area. Anyone who chooses this place as the first scene of the murder would be really mad. I checked the wallet on his body, and there were more than 800 yuan in cash neatly in it, as well as ID cards and bank cards; his motorcycle was lying beside me, and I didn’t notice any of these. what is the problem. It was his feet that caught my attention: he was lying on the road near the sidewalk, and a puddle of sewage about ten square meters had accumulated on the ground due to the heavy rain last night. I don't suspect that there is any poison, even if there is any poison here, the rain will dilute it a lot, not to mention that he is still wearing shoes, so it is not easy to absorb it. Impregnated up, could it be leakage?I found an electric pen, and it turned on as soon as the electric pen was inserted into the sewage. I was still a little worried, so I visited a few nearby units, and a few students from a middle school not far away told me about yesterday's accident. They were also electrocuted when they crossed the road with water.

No current spots were found on the body of the deceased. I have to tell everyone that not all electric shocks will have current spots. If the current enters the human body through water, the typical current spot will not appear due to the large contact area between the electrode and the human body and good contact. On the contrary, there was a hole in the trousers on the inside of the deceased's thigh where the electric current penetrated. I think it is not a big problem to determine the death caused by electric shock in this case. Accident, it turned out to be another accident. I felt a lot more relaxed: no one should be held criminally responsible for this, of course the Highways Bureau had to be notified immediately, they had to come and take a good look.

This case is a bit complicated, and within two days I finished the report and prepared to let Mr. Zheng review it. Unexpectedly, the dossier got stuck in Mr. Zheng's: Mr. Zheng did not express his opinion on this case for two consecutive weeks. It was almost time to close the case, so I was a little impatient. When I arrived at Mr. Zheng's office, Mr. Zheng was holding the file of this case in his hand. Before I could speak, Mr. Zheng asked me: "If this case was an accident caused by electric leakage, then why did the students in the water before come to nothing? What?" This is a question, but it is not absolutely impossible. After thinking for a while, I said, "Everyone's resistance is different, and the amount of lethal current varies greatly from individual to individual." Mr. Zheng pointed to the photo of the deceased's trousers: "This thigh How do you explain the hole on the inside?" "Electric breakdown!" I opened my mouth and answered.

"Have you ever seen a 220-volt shock go through clothes?" This made me speechless. I have never seen a 220-volt shock go through clothes, but who knows what the voltage is there? ?Mr. Zheng waved his hand: "Come on, let's measure the voltage." I saw Mr. Zheng holding a multimeter in his hand. The measurement result of the voltage disappointed me: it was less than 100 volts. This level of voltage, not to mention breaking through clothes, would be difficult to kill. I've asked. The streetlights use 220 volts of electricity. It seems that the electricity leaks here and loses a lot. But there is indeed a hole in the pants of the deceased!I was relieved when I got back to work, it wasn’t a leakage, what was that?When I asked Mr. Zheng a question, Mr. Zheng didn’t answer directly. Instead, he asked me to do an experiment. He asked me to put clothes on a pig and walk through the stagnant water, and then take a GPRS to measure it accurately. The latitude and longitude of the sewage. What kind of mystery is Mr. Zheng playing?I'm so confused. But I still decided to follow Mr. Zheng's arrangement: Mr. Zheng must have an idea in doing so. And so came the opening scene. But after finishing the experiment, I still don't understand what's going on. It's not surprising that a voltage of less than 100 volts can't kill piglets or make clothes break down. Is this voltage too low?What kind of medicine does Old Zheng's gourd sell?I told Mr. Zheng the GPRS measurement data: east longitude 120°40′36″, north latitude 27°58′49″. Just as he was about to ask Mr. Zheng what was going on, Mr. Zheng revealed the answer himself: It turned out that the night of the incident was a thunderstorm. The time did coincide with the time of death, but he was relieved only when he confirmed with GPRS that the latitude and longitude of the lightning strike location were exactly the same. The facts of the case became clear: the unlucky deceased was riding a motorcycle home that night, and a thunderbolt happened to hit him. Most of the current flowed away along his wet coat and the splashed water on the ground, and only a small part It passed through his body, so it didn't leave lightning marks on his body, but the sudden electric current was enough to stop his heart, and it also pierced through the still dry clothes on his inner thighs. But this made me lose face a bit, so I quibbled to Mr. Zheng: "What is different is an electric shock, and what is different is an accident?" Mr. Zheng smiled: "It is the same for us, but it is different for others. If Leakage, the Highway Bureau is liable for civil compensation, and lightning is none of their business, what do you think?" It seems that forensic doctors really can't do without thinking a little bit more.
