Everyone let open the block, then Zhou Hai saw that several extremely clear blood-colored fingerprints, under the action of spraying, appeared on the edge of the guardrail, the fat man raised a face of sweat, facing Zhou Hai grinned.

“Sea, we found our fingerprints!”

And, in the iron, found a few fibers and bloodstains, not knowing whether it was the murderer's."

He was excited and patted him on the shoulder.

“Fat is good!

Oh!

Where does the gap in this guardrail lead to?”

The fat man shook his head.

“I haven’t seen it yet!”

He glanced at the eye, and he packed the physical evidence bag inside the survey box.

“Have you finished the certificate?”

“It is finished!”

“Let’s go and see!”

Big Li could not resist, reached out and grabbed the wire, and leaped over.

Returning to the box of Zhou Hai and the fat man, they dragged them one by one, Zhou Hai was good, when the fat man passed, the big Li's face was red, and the scouts who pushed the fat man behind him almost did not lie down.

The fat man himself was still panicking.

"Ah!

Hold on to me, don't let me fall, even if it falls, it will fall to the opposite side, otherwise I'll crawl here once in vain."

He felt like he wanted to beat him and walked quickly.

It is the bottom of the viaduct, which is almost completely blocked from the sun so the vegetation is not developed.

Several drops of blood on the land began to spread out in the distance, and Zhou Hai fell to his knees and observed carefully with a magnifying glass.

Sure enough, the drop of blood in motion, looking at the direction and length of the burr around the blood droplet, you can judge the direction of the person's travel and the height of the blood drop.

The fat man had come running up and took a quick photo.

“Can you calculate the height?”

The fat man nodded, selected nearly four blood droplets, measured the longest and shortest value of the burr, and the diameter of the blood droplet, and calculated it quickly.

“The height is between 1.2-1.28 meters.

Go in that direction!”

Several people followed the fat man, heading southeast, and the drop of blood of nearly fifty meters disappeared.

However, a pile of ash appeared directly, and a few people were very excited, and a few pieces of unburned knitted fabric were caught in the ashes of Zhou Hai.

"It appears that this is the clothes of the dead, which are collected."

At this time, there was no blood drop and I was not afraid, because several people looked up and saw another guardrail, which was far from the high guardrail they had down, and several people climbed up.

Standing on the road, the investigators were surprised, because they actually came to the east side of the high-speed port, here is the west entrance of the Bianjiazhuang, facing is a spacious eight-lane.

Looking at the passing vehicles, Zhou Hai's eyes fell to a storefront - the national building repair shop.

Outside the door, there were some maintenance tools, two large trucks were parked on the side, and a burst of "shuddering" sound came from the pavement.

Zhou Hai and others quickly hid to turn to the village of the fork of the road, standing here and looking, sure enough the opposite monitoring can not see this position, the repair department is also the north side of the prominent a gas station brand blocked.

Without the order of Zhou Hai, Da Li has already called the phone to the Hu team.

"Head, we found blood and a pile of ashes at the first scene, following the clues, around the other exit, and one of the heads is the national building repair department."

You don't move!"

“Wait, we’ll be here in ten minutes!”

Several people quickly hid their bodies, and the phone informed the vehicle to quietly turn to the west side of the village.

A moment later, the car came, just sitting in the car, the fat man's mobile phone shook.

The call was Dr. Nan, and the fat man answered the phone.

“Fat, you kid, dare to pick up the old man’s phone!”

"Well done, don't say you didn't get those pictures, you lost your craft!"

"Cut, run the old man, know that you are busy, have sent it to your mailbox, next time come to bring me good wine."

"No problem, the burner on this side will bring you five barrels!"

Without waiting for the other party to reply, the fat man has hung up the phone, took a breath, clicked on the mailbox to view the picture, and the pixels have improved a lot.

Da Li swung his head around, saw the third photo, and Da Li slapped in the seat.

“This is Cai Guodong!”

The fat man magnified the photo, a solid black-faced man appeared on the screen, and he was lifting his left arm to wipe the sweat overhead, but this action was also blocking the camera.

There is a figure in a red dress in the front of the picture, and Zhou Hai thought at a time that just those ashes were knitted fabric.

Let the fat man enlarge this position, several people stared at the screen, the red dress woman is side-faced, but the fat man recognized who the man was at a glance.

“The red jasper!”

Several people are very excited, so found that it is a real suspicion of Cai Guodong, and the rest depends on the results of the laboratory.

I thought, a sound of sirens from far to near.

At the head of the Da Li probe, it was the car of the Hu team, which was parked in front of Cai Guodong's door.

Their cars followed suit.

Taking advantage of this idle, the fat man has already told the crazy and Xiaoliang to listen to the crazy, several people's faces are red, this is hot.

The police officers were only wearing police uniforms, and they were still carrying survey suits outside the police uniforms, wearing hat masks, which felt quite sour.

For a moment, Cai Guodong, who struggled for a while, was escorted out of the hand ka0, and Zhou Hai and fat people took the box and got off the bus.

Their vehicles did not stop, whistling to the city bureau.

Zhou Hai they entered the repair department, and the beam held up the camera to record the image.

The fat man watched for a moment and went straight to a toolbox on the northernmost side, where a black rubber-handled cone was picked up by the fat man, while holding a small spray pot in his hand toward the change-cone rod and the handle.

Zhou Hai knew that it was a lunol reagent, and even if the murder weapon was cleaned, the face would still have hemoglobin, and the iron element in it would form a chemical reaction with the reagent, thus turning it into a blue-purple fluorescence.

Sure enough, the blue-purple fluorescence that changed the taper flashed, and the fat man quickly put the change of cone into a transparent physical evidence bag.

Zhou Hai took a closer look, "the top of the re-cone has some irregular depression, which is the mark of the piercing skull."

When Xiao Liang turned around, a toolbox behind him fell to the ground, and the lock of the falling face was broken, and the lid was also dispersed directly.

Inside lies a hammer, the fat man's art is re-grinding, continue to spray lumino (lunol) reagents, this blue-purple fluorescence is more obvious, after all, the wood with a small hole is not easy to clean up.

Zhou Hai squatted down and saw the bottom of a toolbox, and a mobile phone with many water drills appeared, apparently a woman's mobile phone.

At this time, Zhou Hai's phone rang, and the call was the secretary, who was found by the boss, who was locked in the cellar of Cui Hong's family and had been dead for many days.

The madman stood up and said, “I’ll see!”

Bleeding blood:

Blood falls vertically on the ground or on objects, forming round drops of blood.

Its specific shape is also different due to the height of the drop and the direction of motion.

If the blood falls from a height of 0.1 meters, the edge of the bloodstain is completely round;

When falling from a height of about 0.5 meters, the edge of the dot can have obvious jagged;

When falling from 1 meter to a commercial degree, not only can the edge of the dot be seen, but also the dots or line-like small blood drops are often around.

If the blood is moving in the injured person or drips from moving objects (such as vehicles), the blood is elliptical, one end is like astral protrusion, and the tip of the protruding points in the direction of the movement.

Rumino (lunol), also known as luminescent ammonia.A type of blood that cannot be observed by the naked eye at a crime scene can show a very small amount of blood stained morphology (submersible blood response).

Rumino reagents use reagents to identify blood, blood even if wiped, the blood heme will remain, when Rumino reagents sprayed in heme, will produce oxidation with reactive oxygen species, release blue purple fluorescence.It was the Rumino reaction.It is an organic substance used in the identification of blood.
