Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 390 Murder Motive

"Were the footprints left by the murderer?"

"In addition to fingerprints, there are also footprints at the scene, but footprint analysis is really difficult. Here..."

Lu Chuan understood that most of the footprint analysis was to calculate the approximate height of the opponent from the foot length formula.

"Who reported the case?"

"The deceased's wife, she came home and found her husband had been killed."

"There is no need to compare 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 entered the room backwards from the door."

"How...how can you tell?"

"The force on the shoe print is in the wrong direction, 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 a sketch.

"In general, 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 did not belong to the murderer himself. The murderer wore shoes that were at least three sizes too big."

"The height is about 1 meters, the weight is no more than 6 kilograms, and there should be a history of fractures in his left leg."

1.6 meters?

Weighing no more 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 based on 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 absolutely 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 was significantly greater than the force on the outside little toe."

"It is inconsistent with the stress on most people's steps. Unless the opponent's left leg has been fractured and the connection was not complete during the connection, this uneven force will occur. .”

Although Wang Gang couldn't understand how Lu Chuan discovered the uneven force on the footprints, he still chose to report the situation to Liao Junlong.

after an hour.

The victim's wife was arrested. After the other party found out that she was wearing big shoes and forged footprints at the scene, she confessed everything.

The so-called fingerprints were 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 soaked it in a pool of blood.

The purpose is to confuse the public and interfere with the police's judgment.

Obviously the opponent's move was successful, and the Huangzhou City Criminal Investigation Detachment focused all their attention on the fingerprints.

"Has your left leg been broken?"

"I fell down in the winter three years ago."

"Did you go to the hospital to collect the bones, or at the bone setting hall on the roadside?"

"I spent 100 yuan on the Zhenggutang on the roadside, but the connection wasn't very good. But then it started to grow, so I couldn't help it. There was something a little wrong when I walked, but you couldn't tell it unless you looked. How do you know?"

Teacher Lu is 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 considered 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.

When the husband is killed and the wife reports 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.

Moreover, 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 the two said 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 is just 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 nothing good about me."

Woo woo woo.

"I haven't worn a skirt for five years... wu wu wu... 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 him.

"Why don't you divorce him?"

"divorce?"

Ha ha.

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 gently..."

Afterwards, the forensic doctor evaluated the woman's injuries.

"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 unable to help crying.

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.

Husbands and wives are birds of the same forest, and when disaster strikes, they fly separately.

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 the murders are also bizarre.

But this is the only homicide 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 get 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 was over, 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.
