"This is the scene of the crime." Criminal policeman Xiao Wang pointed to an old house surrounded by a police cordon.
This is Linhai City. There are old houses in the bustling city. The houses were built in the 19th century. Today, only these houses connected by a few hutongs still preserve the memory of the past.
On March 21, 2017, around 8:00 p.m., the Linhai City Criminal Police Brigade received a report from an enthusiastic audience that a suspicious case had occurred here, and there were obvious signs of fighting in the open room.
The owner of the house has not been seen for a week.
After investigation by the criminal police at the scene, they finally found a frozen female body in the refrigerator of the house.
After preliminary judgment, it was a murder case.
The Criminal Police Brigade quickly contacted the autopsy department of the judicial appraisal department.
A long cordon has been drawn around the house, and the onlookers have blocked the water outside the cordon.
Xiao Wang took Wang Luo through the cordon to the courtyard of the house.
Guan Yuan, the captain of the criminal police brigade, came up to say hello: "Are you a comrade from the judicial department?"
Wang Luo nodded and glanced at the open door in front of him: "Has the scene been damaged?"
Guan Yuan glanced behind Wang Luo, but he didn't answer him, he just asked, "Where is your team leader, Dr. Li Qing?"
Criminal detective Wang hurriedly explained: "This... Captain Guan, this is the forensic doctor leading the team this time, Mr. Wang Luo."
Guan Yuan looked up and down the thin man in front of him, 1.75 meters tall, of medium build, with messy hair, Bai Jing's face, and a pair of rimless glasses under the bridge of his nose.
Captain Guan didn't speak. He pointed at the corpse and asked Wang Luo to start the autopsy. Wang Luo tidied up his white coat, squatted down, put on latex gloves nimbly, and steadily began to take out everything from the female corpse with tweezers. DNA clues, this is a naked corpse, with a few black hairs and a trace of flesh fibers in the gaps between her fingernails. The hair in the nails was hard and black in color, while the corpse had frizzy, obviously over-dyed yellow hair, so it shouldn't be hers.
Flesh and hair are likely to be murderers.
There were obvious bruises on the corpse's head that had been hit by a blunt object, the subcutaneous blood was still on the forehead, the long hair was messy, the face was haggard, and the muscles were a little stiff. We have to wait for further tests to know. After Wang Luo collected the hair and blood on the corpse, he would get up and leave.
Captain Guan stepped forward to stop him and wanted to ask about the time of death. Wang Luo raised his eyelids and glanced at him. He didn't say a word, just dodged and got into the car, and left the crime scene.
"What's the origin of this kid? You can't speak human words?" Captain Guan was a little dissatisfied with Wang Luo's arrogance.
The criminal policeman Xiao Wang on the side quickly replied: "This is the new deputy director of the identification center from our bureau. Dr. Li has already retired, and now he is in charge of the entire identification center."
Although Captain Guan was unhappy in his heart, it was not easy to put it on his face.
Turning his eyes, he seemed to think of something: "Oh, it's that turtle, I heard that he was admitted to some advanced forensic certificate at a young age, Che, I guess I don't know which boy from the official family, the deputy director so soon. already."
Of course, Guan Yuan didn't know that Wang Luo was not arrogant, but just because of his personality. , Wang Luo automatically classified him.
Wang Luo entered the laboratory without saying hello to his colleagues, and plunged into work.
An experienced forensic doctor will infer an approximate time of death based on the phenomenon of the corpse, corpse temperature, corpse spots, as well as the humidity of the environment, the stiffness of the muscles of the whole body, and the changes in the temperature of the skin color of the whole body.
But some death times will change due to drugs or some weather changes, or scientific instruments are more effective and intuitive.
The most common scientific method for detecting the time of death is eyeball chemistry.
After a person dies, the red blood cells will continue to rupture, and the potassium ions of the red blood cells will enter the vitreous of the eyeball.
This method is not affected by temperature and is more accurate.
The body has been sent to the medical examiner's room in good condition.
Wang Luo took out the liquid in the deceased's eyeball and put it on the instrument to start the test.
Wait until the time of death is checked and recorded.
Taking advantage of this gap, he carefully peeled off the skin fibers under the deceased's fingernails, put it under a microscope, and then performed a DNA comparison, which showed that it was not the deceased's. If the deceased was beaten to death by a blunt weapon and put it in the refrigerator, what weapon did the murderer use? Judging from the traces of the body, the scar on the forehead is square, is it an ashtray?
"Director Wang, Captain Guan asked me to ask you, do you have any findings?" Criminal police officer Wang asked with a probe. Wang Luo didn't lift his eyelids this time. He looked at the data from the test and said, "The time of death is two nights in the night. At three o'clock, there are signs of being beaten before he was alive, and the fatal injury is not known for the time being. Judging from the pupils of the deceased, the mood swings before his death were obvious, and the pupils were obviously enlarged."
Xiao Wang snorted, and then invited Wang Luo to dinner, because today was Wang Luo's first day at work.
As if he didn't hear it, Wang Luo lowered his head and pondered, as if thinking about the case, Xiao Wang was a little embarrassed, and said, Seafood City, second floor, 203, and left the laboratory.
At this moment, the forensic center has finished get off work, and only Wang Luo is left in the laboratory. His teacher Dr. Li said that the scene is the best laboratory for investigating a case and an autopsy. Only our forensic doctor can let the deceased say the last word. words come.
Go to the crime scene.
Today's evidence has proved that the residential house was the first crime scene. Wang Luo took out his work permit and entered the blocked house.
The 80-square-meter house, the furniture was messy, a few chairs fell on the ground, the glass of the fish tank was shattered, three black goldfish had turned their stomachs on the ground, the refrigerator with double doors, the body was already in the morgue of the police station, The drinks and fruits in the refrigerator were put on the table, and the ice cream had melted.
There is a pack of King Furong on the table, a box of Durex, and a few pairs of men's shoes in the shoe cabinet. First of all, it can be seen that the deceased is not single, but should have a boyfriend or husband. Neighbors will find out.
There was ash scattered on the ground, but there was no ashtray. Maybe the ashtray was the murder weapon, and it was very likely that the murderer took it away. Wang Luo was still searching for evidence, the door was opened, and a girl came in. Wang Luo looked back, jeans, sneakers, neat short hair, and the work card of the laboratory technician of the Forensic Identification Center of Linhai Public Security Bureau on his chest.
"Hello, I'm a new laboratory technician, Lin Weiwei, are you Deputy Director Wang?" Lin Weiwei greeted kindly, and Wang Luo recalled that he met at the center in the morning, but he always treats the living. I can't remember the name and face, so I can only say that I have a little impression, so I nodded.
"Director Wang, you're serious, it's noon, and you're here to check it out." Lin Weiwei said a lot, and the rest were all her admiration for Wang Luo.
Wang Luo is the youngest senior forensic doctor in Linhai City. As soon as he returned to China, he was introduced by the teacher and became the deputy director of the center. Coincidentally, the university that Wang Luo attended before studying was the same as Lin Weiwei's school.
Lin Weiwei had heard from her classmates as early as in college that there was a talented senior named Wang Luo, who cooperated with the police and solved several major cases in school.
Now she can work under the leadership of this talented senior, she doesn't know how happy she is.
"Senior Wang, I'm your junior sister, and I'm with Dr. Li..." Before she could finish speaking, Wang Luo patted his head and proposed to go back to the forensic room for further autopsy. Lin Weiwei agreed immediately. A pink motorcycle took Wang Luo back to the bureau.
Zhang Qian was written on the name tag on the corpse in the mortuary of the forensic medicine room. When she opened the body bag, the cold air rushing toward her face made Lin Weiwei feel a little scared. She had also seen corpse specimens soaked in formalin at school. But today I saw a corpse that had just died, and this sense of fear was still very strong.
"Take the corpse out and take it to the autopsy room"
"Ah, let's lift it up," Sun Qian said with a little fear immediately after hearing it.
"Well" Wang Luo nodded: "I found something at the scene, and I suspect that her death may be caused by more than trauma." The two transported the body to the autopsy room.
Sun Qian's cause of death was suffocation.
After the autopsy, Wang Luo found a ring in the stomach of the deceased Sun Qian. This case looked really perverted.
He carefully took it out with tweezers and put it on the tray. With a metallic sound, the disinfectant washed the gastric juices on it, and a dark green ring was exposed.
Lin Weiwei, who followed the voice, returned to the table, looked at the ring carefully, and said confidently: "This is the new model of Jinliufu, which means that love will last forever. Look at the name engraved on the inner wall of the ring, Shao Kuan, this is very Apparently a man's name."
"Shao Kuan, could this be Sun Qian's boyfriend?" Lin Weiwei asked.
Wang Luo nodded, it seems that this Shao Kuan is suspected of committing a major crime.
These are the only clues I have seen so far. At this time, the criminal policeman Xiao Wang called and said that Shao Kuan had been caught. Now this person is being interrogated in the interrogation room of the city bureau. It stands to reason that all the clues on the corpse have been analyzed, and the task of the forensic doctor is over. However, there are two criminal police officers on maternity leave in the bureau, and there is a shortage of manpower, so Wang Luo also came to the interrogation room at the repeated request of the criminal police Xiao Wang. .
