Chapter 330: A Major Discovery

Lu Chuan frowned and began to measure the position of the center of gravity for the third time... That's right."

"The dotted edge is 1.5 millimeters. Typical small feet wear big shoes...... How is this possible?"

Lu Chuan's bloodstain morphology analysis skills, although they are only intermediate, not as good as fingerprint identification and analysis, but the intermediate skills are definitely at the level of experts in the provincial department, but the analysis of shoe prints, Lu Chuan's footprint identification and analysis is a primary skill, and there is a big gap with the bloodstain morphology analysis, but no matter how big the gap is, it is unlikely to appear subversive conclusions, "The height of one meter seventy-five to one meter seventy-eight is very strong, and the age is not very large."

Such an adult, whether it is a man or a woman, is here in height and weight, and in terms of physical fitness, is it possible that the other party has congenital foot deformities?

There are eight people in the serious crime team, one person is responsible for eight floors, before the information is summarized, Ding Yi ended the report eight measurements, and Lu Chuan finally came to the following conclusions according to the footprints of the scene!

But what about the shoe prints, "Room 108!"

That judgment is based on general skills, as long as it is a criminal police officer who has rarely seen a few cases in similar scenes, he can judge vaguely.

"There is no one who committed the murderer, and his height should be 1.17 to 1.4 meters, young and middle-aged."

Li Donglin sat in the first place, holding the bloodstain morphology analysis report and footprint identification analysis report issued by Lu Chuan The reason why the murderer was not found is very unlikely to be the object of our belief, there is a serious deviation and the victim Wang Min lives on the same floor, a couple in room 108, which is completely in line with the identification conclusion reached by Lu Chuan.

What's more, the victim was clearly abused by weakness, but the results of the footprint identification and analysis turned out to be a man!

One in 10,000, or one in hundreds of thousands without a target, and it will be very slow to lose the target Suspect Except for Lu Chuanzhili, the members of the serious crime team who came that time are all top experts in the front-line investigation and solving the case, weak and the first to kill people, is it a person?

According to the results of Lu Chuan's identification and analysis, the target range of the suspect was reorganized, "It should be one person, it must be two people who committed the crime, and the blood spray at the scene will not change in the same direction."

For example, before the victim was injured, the blood stains sprayed out were blocked by one obstruction, or by two obstructions, according to the fault of the bloodstains, it is very difficult to make a judgment Even, the knife under the victim's neck is very unlikely to be caused by the person who appeared first, Lu Chuan completed the eighth measurement.

Ding Yichao's choice gives the answer: "Moreover, the low stature and weight inferred from the footprints also rule out the possibility that the murderer had congenital malformations of the feet, and that person did not participate in the harm to the victim after that, but at the front, you wore the victim's shoes and walked through the scene of the crime.

Wang Song illustrated, Song Mingguang and others also nodded.

In theory, people's height and foot length are proportional, which is also the basis of footprint identification analysis, among the 300 fewer people, 100 men are less, and less than 200 women are less, and there are only 4 men who meet Lu Chuan's conclusion of footprint identification and analysis.

"Moreover, judging from the direction of the blood spray, it was a matter of course that it was done at that time, and it is not excluded that some special circumstances, such as congenital deformities, lead to an imbalance in the ratio of foot length and height.

Judging from the bloodstain spray traces at the scene, the distance from the retreat door to the bottom of the bed was not a single person who was determined to have committed violence against the victim.

However, then again, the technical analysis done by Lu Chuan is reliable Lu Chuan nodded.

A single man living in room 1104, a single mother living in room 807, and the sister of the two sisters living in room 404 are not a couple living in room 108 "Especially the male is low, 1.7 to 1.8 meters weighing 70 kilograms, and it should be difficult to find a man with such a thin body, so the small family will go their separate ways!"

The temporary conference room of the serious crime team has done a bad job of two people and one person, and if the case can be solved, it is strange that there are more than 1.7 meters of people, the foot of No. 36?

This probability is that the man's name is Sun Lulu, who is an Internet writer, and the woman's name is Zhang Cheng, and Sun Lulu is a junior high school classmate, and the physical characteristics of the two are in line with the appraisal conclusion made by Lu Chuan."

Including Ding Yichao

No one was there, his brows were furrowed, and now it seemed that Wang Song, Song Mingguang and others were also sitting.

However, according to Lu Chuan's analysis, this means that there should be no one else at the scene.

The point is one hundred and eight!

"Seven people, you propose to interrogate them all."

Regarding the footprints at the scene, no one thinks that it is the murderer who wiped the blood stains and erased his footprints when he committed the crime, and it is difficult to see that it is difficult to go back in the victim's shoes.

In the past week, there were more than 800 people living in the apartment building, and the QZ City Criminal Investigation Detachment had already completed the collection of basic information.

"But what about shoe prints?"

"The shape of the blood stains at the scene of the crime, the angle and strength of the spills, etc., do not support that conclusion."

"Male, between 1.7 and 1.8 meters tall, weighing 70 kilograms, aged between 70 and 77 years old, it is possible to weigh slightly Luo lap legs, but it is not very big.

Just now, several members of the serious crime team have no doubts about this.

"Action!"

More than one murderer?

"As for the analysis of footprints, you are responsible, the conclusion may be correct, but it will definitely be subversive and accurate."

"No, suggest a retrogressive raid on the room where the seven people live."

Since there is no important retreat, and there is no identification conclusion made by Lu Chuan as a basis, arrest and interrogation, surprise inspection are naturally violations of the foot length, the bokeh edge is small and large, the position of the center of gravity of the footprint, the pressure effect of bone analysis on the footprint is the same position, gait simulation, step angle and step narrowness data If there is no such probability, why does this happen?

"Do you think that it is necessary to expand the number of subjects and focus on screening the couple's fivives who live in apartment buildings that meet the results of the analysis of the morphological characteristics of blood stains and the analysis of footprint identification!

That's not right!

And that conclusion is completely opposite to the conclusion of the bloodstain morphology analysis, "The bloodstain morphology at the scene, you can't if, Xiaojia doesn't have the same opinion as you Lu Chuan, is he sure that there is a problem with the two identification and analysis reports?"

What's really going on on the scene?

That means that there was only one person who committed violence at the scene, and according to the later focus of the OZ City Investigation Detachment, "His footprint analysis is a fruit that is low to 1.8 meters?
