675. Chapter 675 - Eye Chemistry
"When the body temperature is tested, the mercury in the vacuole is heated and expanded, and the mercury can rise from the neck to a certain position in the tube, and when the thermal equilibrium with the body temperature is reached, the mercury column is constant. There is a narrow part at the junction between the vacuole part of the thermometer and the thin tube www.biquge.info which can prevent the mercury from falling on its own, so as to detect the temperature, and the mercury column must be shaken down before it can fall, that is, it is thrown downward. Therefore, even if it is placed in cold water, the thermometer will not cool down on its own. ”
Zhao Xiaohu adored and said: "So that's the case, I always thought that the temperature would come down if I put it in cold water." ”
Long Zihan stood up and said to Liu Yuanheng on the side: "White coat, thermometer, the deceased is either a nurse or a doctor, let's start investigating the identity of the deceased when I go back." ”
"Yes. ”
At this time, Erin came back from a circle around the neighborhood and said, "There are no other clues at the scene, let's ......"
Long Zihan looked around and said helplessly: "Let's go back and talk about it." ”
Police station, conference room.
The Chuyi people will report: "The deceased female, pubic symphysis facial bone is denser. The ventral border is gradually formed. The slope is widened, its lateral margin is crested, and it is presumed to be 35 years old. ”
Zhao Xiaohu said: "To be honest, I have always felt that judging age by bones is quite magical. ”
The Chuyi took out a few photographs and X-rays and said: "The deceased's skull bones were all clearly fractured in the corresponding parts of the left top, occipital region, and right temporal roof, and the fracture lines that radiated from the central area of the injury to the periphery all existed independently. Moreover, the site of severe cerebral contusion is also consistent with the corresponding part of the skull fracture. ”
Wang Xiaoguang said: "Judging from the location and direction of the wound, the murderer attacked from behind the deceased. ”
Mo Bei sighed and said with emotion: "It's so serious, it seems that the murderer has used every stick to eat milk, how much does this hate the dead?"
Liu Yuanheng said: "The common motive in homicide cases is love and money. ”
Long Zihan shook his head and vetoed: "This case is not. ”
Mo Bei asked suspiciously, "Why?"
Erin analyzes: "Aggression and violence are generally divided into overt aggression and covert aggression. Overt is face-to-face with the victim, while covert attack is done by covertly, deceptively, or despicably. In this case, it was a covert attack. ”
Zhao Xiaohu asked, "What does this have to do with the question we asked?"
"Covert aggression shows the attacker's lack of self-confidence, or low self-esteem. Therefore, there should be a certain difference between the murderer and the deceased in terms of physical fitness or stature. He had a reason why he had to kill the dead, so in order to make sure that nothing went wrong, he chose to beat the sticks in the back. ”
After listening to Erin's analysis, Long Zihan said: "To sum up, the murderer is so purposeful and premeditated, it is not like it is for money, but more like venting anger. ”
Long Zihan asked, "What about the time of death?"
Chu Yi said: "Judging from the chemical hair of the eyeball, the time of death of the deceased was about nine o'clock last night. ”
Zhao Xiaohu asked, "Eyeball chemistry?"
Chu Yiren frowned slightly, a little reluctant to say.
Wang Xiaoguang explained: "The thermometer on the deceased's body shows 40 degrees, which indicates that the deceased is likely to be immersed in 40 degrees of water after death, which will definitely change the state of the victim's body after death." The eyeball chemistry method means that the red blood cells in the corpse will continue to rupture regularly, and the potassium ions in the red blood cells will continue to enter the vitreous humor of the eye in a regular manner, according to which the time of death can be accurately determined. This method is not affected by the outside temperature, so the measured time of death is more accurate. ”
After saying it in one breath, Wang Xiaoguang couldn't help but pick up the water glass in front of him and take two sips to moisten his throat.
This is the reason why the Chu Yi people didn't want to relieve their hunger just now, they talked too much and were a little tired.
Seeing that Wang Xiaoguang had already done it for him, Chu Yiren picked up the bargain and nodded and said, "That's it." ”
"I see......"
"The time of death detected by the chemical method of the eye is nine o'clock, if you look at it according to the conventional detection method, what is the time of death?"
"It's about two to three hours early. ”
Long Zihan nodded, looked at Liu Yuanheng, and said, "I said before that the deceased may be a doctor or nurse, how is the identity investigation of the deceased?"
Liu Yuanheng said: "The people below have already gone to the hospital to inquire, and there should be results soon." ”
However, Liu Yuanheng's mouth was very fast, making Long Zihan wait for five hours.
When he came to Long Zihan's office, Liu Yuanheng reported: "The deceased's name is Du Weiqi, 35 years old this year, and he is a pediatrician at the Central Hospital. Last night the deceased worked a night shift, from half past five in the evening to eight in the morning. ”
"I went to work at half past five in the evening, and the time of death was nine o'clock...... What was she doing in between? Where did she go?"
Liu Yuanheng shook his head and said, "I have inquired, but other doctors and nurses haven't paid much attention." ”
Long Zihan nodded and said, "Wait a minute, I'll go there myself." By the way, did you notify the family?"
Liu Yuanheng nodded and replied: "I sent someone over to inform me, and I will come over soon to identify the body." ”
The arrival of the family of the deceased made the police station suddenly "lively".
When the crying was quiet, Long Zihan went over to see people.
Long Zihan asked, "Ms. Du worked the night shift last night, what time did she leave home?"
The husband of the deceased said: "I left around five o'clock, she was very strict with herself, and she was never late for work." ”
Long Zihan asked again: "What enemies does she have, or who has she offended?"
The husband of the deceased asked, "Who can she offend as a doctor?"
His words reminded Long Zihan that who can a doctor offend?
This reminded him of what Long Yaqiu had said earlier that a pediatrician had treated a three-year-old child to death. Could it be such a coincidence?
Long Zihan asked tentatively, "Have there been any medical accidents recently?"
The husband of the deceased frowned slightly and said, "No." ”
Hearing his answer, Long Zihan thought, could it be that he guessed wrong?
I heard the husband of the deceased say, "However, I don't know very well, she rarely talks about work." ”
Subsequently, after Long Zihan learned about Du Weiqi's recent situation with him, he said goodbye and left.
He found Mo Bei and Erin and told the central hospital.
Long Zihan found the pediatrician and chatted with the deceased's colleagues about the deceased's recent situation and personality.
Long Zihan asked, "Do you remember, what time was the last time you saw her last night?"
"I saw her at half past five and said hello to her. Later, I never saw him again. ”
