Chapter 390 Motive for Murder
“Were the footprints left by the murderer?”
“The only fingerprints at the scene are footprints, but footprint analysis is too difficult. From our side...”
Lu Chuan understands that most of the footprint analysis is to use formulas based on foot length to calculate the approximate height of the opponent.
“Who reported the case?”
"The wife of the deceased, when she came home, she found that her husband had been killed."
"There is no need to compare the fingerprints. The murderer should be the wife of the deceased."
"Huh? Wife?"
What's going on?
Before Wang Gang could ask questions, Lu Chuan took out the photos of the footprints in the file.
"The murderer did not leave in a hurry, but carefully planned the direction of his footsteps. In fact, the murderer walked backwards from the door and entered the room."
"This...how can you tell?"
< br>"The force direction of the shoe print is wrong, opposite to the normal forward direction, so the other party must have entered the room backwards."
Lu Chuan did not explain in detail, but picked up a pen and wrote next to it, drawing Made a sketch.
“Generally speaking, the direction of movement of a person and the direction of stress on the sole pattern should be opposite, but the direction of this series of footprints is exactly different.”
"Also, the shoes do not belong to the murderer himself. The murderer wore shoes that were at least 3 sizes too big."
"The height is about 1.6 meters, the weight is no more than 50 kilograms, and the left leg should be A history of fractures.”
One meter six?
Weighing less than fifty kilograms?
The figure of the reporter suddenly flashed in Wang Gang's mind.
The other party is indeed of this shape.
But how could Lu Chuan figure it out with a series of footprints?
Although Huangzhou City Criminal Investigation Detachment’s on-the-spot investigation is not very good at footprint analysis, they can use formulas.
Based on the shoe length of the footprints, it was determined that the murderer's height should be between 1.7 and 1.8 meters.
This is definitely the opposite.
And how did Lu Chuan know that his left leg was fractured?
Seemingly sensing Wang Gang’s confusion, Lu Chuan took the initiative to explain.
“Compared to the pressure on the inside and outside of the murderer’s left foot compared to his right foot, the force on the inside big toe is significantly greater than the force on the outside little toe.”
“He Da The stress on most people's steps is inconsistent. Unless the opponent's left leg has been fractured and the connection is not complete during the connection, this uneven force will occur. "< br>
Although Wang Gang couldn't see how Lu Chuan discovered the uneven force on the footprints, he still chose to report the situation to Liao Junlong.
An hour later.
The victim's wife was arrested. After the other party knew that she was wearing big shoes and forging footprints at the scene, she confessed everything.
The so-called fingerprints are actually those of the deceased. After killing the victim, the victim's wife wiped out the fingerprints, deliberately held the murder weapon with the deceased's hand, and then dipped it in a pool of blood.
The purpose is to confuse the public and interfere with the police's judgment.
Obviously the other party succeeded in this move, and the Huangzhou City Criminal Investigation Detachment focused all its attention on the fingerprints.
"Have you ever had a fracture in your left leg?"
"It fell in the winter three years ago."
"Did you go to the hospital to pick up the bones, or at the bone setting hall on the roadside? ?”
“I spent 100 yuan on the Zhenggutang on the roadside, but the connection was not very good, but it has grown, and there is nothing I can do. There is something wrong when I walk, but I don’t look at it. If you don’t, you can’t tell, how do you know?”
Teacher Lu, you are truly a god!
He is indeed a genius. In less than 10 minutes, he solved a large number of murder cases that the police in Huangzhou City had not solved for a week.
Of course, this does not mean that Huangzhou's criminal investigation detachment's criminal police are incompetent, but that the current criminal police technology here needs to be further improved.
Lu Chuan has systematic skills at hand, which can be regarded as a dimensionality reduction compared to ordinary investigation detectives.
The wife of the deceased was actually the first person who came under the suspicion of the police.
The husband was killed and the wife reported the crime. There is no need to look at anything else. It is right to directly investigate the wife first. However, the analysis of fingerprints on the murder weapon has been unsuccessful. The footprints left by the murderer were obviously those of a man, and the suspicion of the deceased's wife was cleared.
And the time when the deceased's wife chose to kill her husband was obviously planned in advance. It was exactly when his husband had conflicts with several people.
“Why did you kill your husband?”
According to this week’s investigation, neighbors and relatives of both of them reported that the couple had a good relationship.
In the surrounding circle of friends, they are considered a model couple.
Both of them have good family conditions. They have cars, houses and savings. It can be said that their lives are prosperous.
“Why?”
The woman smiled miserably: “In your eyes, in the eyes of my friends and relatives, we are a model couple, right?
“But he doesn’t even What a beast! "
The woman became more and more excited. She suddenly tore open her collar and pulled open her own collar: "Look, this is what he left for me! ”
The woman is actually very beautiful, with a plump figure, fair skin, and black hair.
But who would have thought that there would be hideous burns under the collar of his neck.
“For seven years, he has abused me every day. There is not a single good thing about me.”
Uuuuuuuuuuuuuuuu.
"I haven't worn a skirt for five years... Wuwuwu... I want to kill him! I must kill him!"
The woman was already on the verge of emotional collapse, and this was obviously not the right time to continue the interrogation.
Two female police officers came in and began to comfort them.
"Why don't you divorce him?"
"Divorce?"
Haha.
The woman's smile was even worse: "I mentioned it once, and he hit me once. Then I didn't dare to mention it anymore, so that he could hit me more lightly..."
Afterwards, the forensic doctor examined the woman's injuries. identification.
“There were extensive burns on the skin, including water burns and cigarette butt burns, as well as knife scratches and whiplash injuries.”
The results of the appraisal made the female police officer handling the case unbearable. I couldn't help but cry.
When a woman takes off her clothes, there is no good spot on her body, especially her private parts, which have multiple layers of scars.
After Lu Chuan learned about the situation, he was so stunned that he was speechless.
Husband and wife are originally birds of the same forest, but they fly apart when disaster strikes.
Although Lu Chuan has not been in the police for a long time, most of the several cases in which his wife or husband were killed were committed by couples.
The motives for killing are also all kinds of strange.
But this is the only homicide case caused by long-term domestic violence.
"How did she endure it for so many years?"
The two were originally college classmates and fell in love for four years. After graduating from college, they came to a southern city to get married and start a family.
How did things develop to this point?
With emotion, Lu Chuan shook his head. Huangzhou's case was solved, but Wang Lili's murder case was still waiting for him.
After the husband-murder case ended, the Huangzhou City Criminal Investigation Detachment also freed up more manpower to work on Zhang Hui’s side, and the investigation speed improved a lot.
Lu Chuan is the most leisurely one now. He is not good at troubleshooting this kind of thing, and there is no shortage of him.
We are chatting in Liao Junlong’s office at the moment.
