Luo Chuan pressed his body against the door, listened to the situation in the door with his ears, and after making sure that there was no one in the house, Luo Chuan took out a silver shiny thing from his pocket.

Chang Yeye's eyes suddenly lit up, and he blushed with excitement and said to Luo Chuan: "You still have this skill, do you want to break into the door, sneak into the room, and then ......?"

"Stop, what are you thinking, you can see what it is. Luo Chuan interrupted Chang Yeye's brain, and then lifted the thing in his hand, and from the moonlight through the corridor window, it could be seen that Luo Chuan was holding a bunch of keys in his hand.

Chang Yeye's face flushed, she originally thought that Luo Chuan was going to take a wire and sneak in so quietly.

This key was borrowed by Luo Chuan from Wang Yue from the community administrator, just waiting for this moment to come, because it is impossible for the kidnappers to stay here all the time, there will always be a day when the next move will be made, and after the kidnappers are transferred, Luo Chuan can go to this room to investigate, and there will always be some clues.

Luo Chuan inserted the key into the lock hole, slowly twisted the lock cylinder, only to hear the click of the lock and opened, Luo Chuan slowly opened the door, and after a general sweep of the house, he made sure that there was no one in the house again, and then pulled Chang Yeye and walked in, and then turned around and closed the door.

Chang Yeye wanted to say that he was not nervous at this time, it was false, after all, the kidnappers were still in this house the day before, if there were still people in the house, then the two of them would not be able to escape if they were winged.

The air in the house was not as muddy as expected, and the dust in the air was only a little there, which further confirmed that someone in the house had been in the house for a while recently.

Luo Chuan walked to the window and found that the window sill on the right side of the window was covered with dust, but the left side was relatively clean, Luo Chuan glanced at the structure of the window, which was the kind of curved window that was common on the market, opening from left to right and from the outside to the inside.

This can be concluded that someone has recently opened this window, so the dust on one side is blown away by the wind, and it naturally looks relatively clean.

Luo Chuan came to a door on the right side of the house and gently pushed the door open. Seeing that there are beds, wardrobes and other furniture in the house, it is deduced that this room should be the bedroom where the owner lives.

Luo Chuan's gaze kept moving around the room, and suddenly, he noticed that the floor behind the bed seemed to have a touch of brownish red.

Luo Chuan walked into the bed, looked at the striking maroon on the floor, and slowly squatted down.

Blood stains are the most important specimen in the examination of physical evidence, and the conclusions of the examination often provide very important clues and evidence for the detection and trial of the case.

Luo Chuan slowly leaned down, almost lying on the ground, Chang Ye Ye did not bother Luo Chuan when he saw this, but stood aside and watched silently.

Luo Chuan gently sniffed the area where the maroon was located, stretched out his finger and pressed it hard, put it to his mouth and dipped it lightly with his tongue, and then frowned.

"Did you find anything?" Chang Yeye asked in a low voice.

"Fishy, salty, and rusty, the maroon red of the ground must have been formed by the drying up of human blood. “

When Chang Yeye heard this, he shuddered, and hurriedly ran to Luo Chuan's side, looking at the pool of blood with uneasy eyes.

"Fresh blood is bright red, and then with evaporation, concentration, drying, and changes in hemoglobin, it will slowly turn into dark red, brown, brown or gray-brown eye color, and it has been at least 24 hours since the change in the eye color of this blood. “

"The next step is ......," Luo Chuan said to himself.

During his time in high school, Luo Chuan came into contact with a book on forensic technology tutorials, which talked about the skills of searching and analyzing some on-site physical evidence and traces, which made Luo Chuan very interested, and after reading it several times, he kept it in mind.

Due to the lack of inspection instruments and the help of special inspectors in the inspection team, these so-called precise and accurate inspection methods obviously cannot help Luo Chuan, so they can only be inspected by the naked eye.

Luo Chuan took out a notepad that occupied a small area, and then started to write on it.

"Direction of blood stain distribution: Splash from southeast to northwest. “

"Location of the blood stain: from the southeast corner of the bedroom to the side of the bed. “

"Shape of blood stains: Splattery blood stains, varying in size, different shapes, relatively scattered, and initially suspected to be caused by repeated blows to the injured bleeding area. “

"Bloodstained eye color: maroon-red. “

"Site of bleeding: It is inferred that the abdomen is beaten with external force, resulting in bleeding from internal organs. “

"Bleeding volume: about 200ml. “

"Blood drop height: about 12 centimeters. “

......

After remembering the results of this series of analysis, Luo Chuan stood up, glanced at Chang Yeye beside him and said, "Let's go, go to the living room and have a look." “

"You're so powerful, you can draw so many conclusions just by looking at this blood. Chang Yeye's eyes flashed with brilliance, and his face was a little flushed and looked at Luo Chuan.

Luo Chuan smiled, and then walked out of the bedroom, Chang Yeye followed closely behind, and came to the living room again, Luo Chuan's eyes suddenly became sharp, Chang Yeye was startled, thinking that someone was coming, and instinctively hugged Luo Chuan's arm.

Luo Chuan gently broke free of Chang Yeye's arm holding him, took out his mobile phone from his pocket, and turned on the flashlight function, only to see that the room that was originally a little dark instantly had a bright light.

Luo Chuan slowly walked to the door, and swept the ground with the light of the flashlight, and when he swept to the position in front of the shoe cabinet not far from the door, the corner of Luo Chuan's mouth hooked up a smile.

"Caught their fox tails. “

Most of the more obvious footprints can be found by direct observation with the naked eye under natural lighting, but for the footprints with very weak contrast, it is necessary to be good at using natural light and artificial light to observe, and constantly adjust the angle of lighting when observing.

Obviously, Luo Chuan used this method just now to find footprints that may most likely be left by those kidnappers.

"The single footprint is large, about 24 cm or more in length, the pattern is thick and deep, the stride length is long and narrow, the stride angle is small, and the foot is strong, and it is characterized by male footprints. “

"Medium height, about 171cm. “

"The step is steady, more regular, the step angle is increased, the forefoot pressure is slightly lighter than the heel, the kicking and digging marks are not obvious, there are trace scratches and pick marks, and the age is about 29 to 39 years old. “

"The characteristics are uniform, the body is well-proportioned, and it is between fat and thin. “

......

Chang Yeye's mouth had grown into a big O-shape at this time, she never expected that Luo Chuan would be able to deduce so many conclusions just by looking at a broken footprint, what age, height, and weight were all calculated, and there was a feeling of watching a movie.

"How did you find your height?" Chang Yeye couldn't help but ask curiously.

"Multiplying the footprint length by 6.876 is about an approximation of height. “

"What about age?"

"Look at the features between two adjacent footprints. “

"What about weight?"

"You talk a lot!"

Chang Yeye stuck out his tongue and didn't continue to ask, but looked at Luo Chuan with his cheeks and eyes blinking.

At this time, Luo Chuan's heart is doing a fierce struggle, the kidnappers transfer the hostages, definitely has its purpose, it is impossible to simply want to change the detention environment for the hostages, and the transfer time is less than 24 hours, at this time, if you follow up the investigation, it must be the best time.

But Luo Chuan didn't want Chang Yeye to be in danger, because she had no ability to protect herself, once an accident happened and Chang Yeye had an accident, then Luo Chuan's conscience would definitely be condemned for a lifetime, and this kind of thing was absolutely not allowed to happen by Luo Chuan.

But looking at Chang Yeye's posture, it is impossible to want her to go home, it is clear that I will follow wherever you go, thinking of this, Luo Chuan sighed helplessly, and turned to look at Chang Yeye.

"Ye Ye. “

"What's wrong?"

"Why don't you go back to ...... first?"

"Don't!"

Luo Chuan was helpless, this trick really didn't work, looking at Chang Yeye's extremely serious and serious expression, Luo Chuan didn't know what to say for a while.

"I ...... I won't bother you, I'll just be there for you. Chang Yeye said with a dark look in his eyes.

Luo Chuan knew that Chang Yeye mistakenly thought that he had affected him, and then thought about it, gritted his teeth and said.

"Let's go, go arrest ......"
