Chapter 4: Skeletal Reasoning

Mo Yufei's answer made Jiang Xiran stunned directly, especially Lu Ke, who looked at Mo Yufei in a daze, and was a little distracted for a while.

She is a criminal policeman who has just been interned and turned regular, not to mention whether she has any experience in participating in the detection of homicide cases, just talking about the current corpse mutilation case, she does not know anything, and with Jiang Xiran's few words, she directly said that the murderer is a butcher.

It's terrifying!

Jiang Xiran's face didn't have too much expression, she just nodded, which was an affirmation of Mo Yufei.

Then, Jiang Xiran came back to his senses and continued: "The age of the deceased is between twenty-one and thirty years old, there is no abnormality in bone development and nutrition, and the specific bone age still needs X-ray detection. According to the maximum length and functional length of the tibia and fibula, the height of the deceased was about 170 cm, and the upper and lower error would not fluctuate by more than 5 cm. ”

"Great, with these clues, it is a very important basis for us to determine the identity of the deceased." Lu Ke took a deep breath, a smile appeared on his face, and habitually praised Jiang Xiran: "Jiang Da Beauty is really professional. ”

"It's just the most basic skeletal knowledge of forensic anthropology." Jiang Xiran said lightly, still without any expression on his face.

Lu Ke was deflated again, he shrugged helplessly, and let out a long breath: "Okay, then I'll wait for your autopsy report." ”

After speaking, Lu Ke left the forensic department with Mo Yufei. Calculating the time, Ling Zizhen and they should have come back from the investigation of the scene, and they should urgently hold a case analysis meeting later.

As soon as Lu Ke stepped out of the dissection room with his front feet, he suddenly poked his head back and said to Jiang Xiran: "If you smile, you must be very beautiful." ”

After hearing Lu Ke's words, Jiang Xiran was stunned, and when she came back to her senses, Lu Ke had already left with Mo Yufei.

Jiang Xiran looked at the place where Lu Ke disappeared last, and a long-lost smile appeared on his face.

"Jiang Xiran is that kind of character, she is not aimed at you, she is aimed at all of us." In the corridor, Lu Ke smiled and said casually to Mo Yufei.

Mo Yufei didn't speak, just nodded slightly.

"But your performance today really gives me a long face, the butcher's judgment is very professional and accurate. It is very powerful that a newly recruited criminal police officer can have such a keen judgment. Do your best work, and your future is limitless. Lu Ke looked at Mo Yufei as he walked, with an appreciative smile on his face.

"Thank you, Team Lu, for the compliment."

Being recognized by the captain of the criminal police, Mo Yufei's heart was very happy, and he made an unusually firm voice.

Hearing Mo Yufei's official answers, Lu Ke shook his head with a smile and said with a smile: "You are really the same as when I first came to the criminal police team, dumbfounded." In the future, you don't have to be so restrained, here, everyone is more easy-going. ”

As soon as Lu Ke finished speaking, he immediately added: "No, it's the entire Jing'an City Public Security Bureau, except for Jiang Xiran, everyone is more easy-going." ”

Hearing Lu Ke's slightly joking words, Mo Yufei's face also showed a hint of a smile.

"By the way, there's a case analysis meeting later, and it's a case we're investigating. You didn't attend the site and may not know much about some of the content. You listen carefully for a while, and if you don't understand something, you can ask at any time, it's okay. Every criminal police officer is constantly growing in the process of solving cases one by one. After Lu Ke finished speaking, he showed an affirmative expression.

These words were said to Lu Ke when he first joined the criminal police team.

Now, he gave these words to Mo Yufei again.

When Lu Ke returned to the criminal police team with Mo Yufei, Ling Zizhen had already returned from leading the team to investigate the scene, all kinds of information had been transferred to the computer, and all kinds of physical evidence had been sent to the trace examination department and the laboratory department, waiting for their test results.

In the office of the criminal police team, the first case analysis meeting of the corpse mutilation case began.

Lu Ke spoke first: "According to the preliminary autopsy results of the forensic medical department, the deceased was a woman, aged between twenty-one and thirty, with a height of about one hundred and seventy centimeters, and the time of death would not exceed twenty-four hours. According to the current information of the deceased, the city-wide investigation of the missing person must determine the identity of the deceased as soon as possible. ”

As soon as he finished speaking, he hurriedly added: "It cannot be limited to this city, but must search for missing persons throughout the province." ”

After Lu Ke finished speaking, Ling Zizhen pressed the mouse and used the projection equipment in the office to cast the photos of the scene investigation on the white screen.

"Let me talk about the investigation of the scene, the scene of the crime was on the side of the road in the suburbs of Jing'an City, and the body was dumped in the middle of the night, and there was no monitoring and eyewitnesses. A five-meter-long droplet of blood was found on the road, which flowed from west to east, dripping naturally due to gravity. The body was packed into a black plastic bag, and the height of the blood dripping was about 20 centimeters, depending on the area where the blood was splashed. ”

After Ling Zizhen finished speaking, he continued to press the mouse, and a photo of a fragment of a black plastic bag found at the scene of the crime appeared on the white screen.

"The murderer used a large black plastic bag that is more common on the market, this plastic bag is thickened, very strong, and used to lift heavy objects, and the length of this specification should be about 70 centimeters. If the killer was a normally developed adult male, then his height should be around one meter seventy-five. ”

Ling Zi really guessed that he was very professional, and he calculated the initial height before the blood dripped according to the area where the blood was splashed. Combined with the specifications of the black plastic bag, the length of the arm was calculated, and finally combined with the calculation of the proportion of human bones, the height of the suspect was obtained.

Mo Yufei sat in the corner of the room, listening to everyone's speeches, and felt sincere admiration for these forensic technical police.

"Why is there only a five-metre trail of blood on the road?" A criminal policeman sitting opposite Ling Zizhen made a very puzzled voice.

His name is Su Simeng, and he is known as Lu Ke's left and right protector along with Ling Zizhen.

If Ling Zizhen focused all his skill points on on-site investigation and trace inspection, then Su Simeng focused all his skill points on knowledge. He is known as a walking encyclopedia, an eight-core brain, and everyone calls him "jack of all trades".

Ling Zizhen pressed the mouse, and a map near the crime scene appeared in front of everyone's eyes: "This is a highway in the suburbs, there is no one nearby, after the murderer kills and breaks the body, if you want to throw the body, there will definitely be a means of transportation." Therefore, the sudden appearance of this five-meter-long droplet of blood is very likely to have been left by the murderer when he got out of the car and dumped the body. ”

In criminal cases, ruts are a very important part of the trace inspection work. By the type of transportation, you can determine a lot of information such as the murderer's habits and family background.

But at the scene of the crime this time, there was nothing on the road except blood......
