Advocate for the deceased

Chapter 45 High Speed ​​Suspicion (9)

Everyone got out of the way, and at this moment Zhou Hai saw a few extremely clear blood-colored fingerprints appearing on the edge of the guardrail under the effect of the spray. The fat man was sweating all over his face, and smiled at Zhou Hai.

"Haizi, we found the fingerprints!
Moreover, a few fibers and bloodstains were found on the iron net, and it is not known whether they belonged to the murderer. "

Excited, Zhou Hai patted him on the shoulder vigorously.

"Fatty is great!

what!
Where does the gap in the guardrail lead to? "

The fat man shook his head.

"I haven't seen it yet!"

Zhou Hai glanced at the evidence bag he put in the investigation box.

"Have you finished obtaining the certificate?"

"It's over!"

"Then let's go and have a look!"

Da Li couldn't bear it anymore, reached out and grabbed the barbed wire, and jumped over.

Turning around, he took Zhou Hai and the fat man's boxes, and dragged them over one by one. Zhou Hai was fine, but when the fat man passed by, Da Li's face turned red, and the investigator who pushed the fat man behind him almost fell down.

The fat man himself yelled in panic.

"Yeah!

Push me, don't let me fall, even if I fall, I have to fall to the opposite side, otherwise I will climb up in vain. "

Zhou Hai resisted the feeling of wanting to beat him, and walked forward quickly.

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

Several dripping bloodstains on the ground [1] gradually extended to the distance, Zhou Hai knelt down on the ground and observed carefully with a magnifying glass.

Sure enough, it was a moving blood drop. Looking at the direction and length of the burrs around the blood drop, one could judge the direction of travel of the person and the height of the blood drop.

The fat man had already run over huffing and puffing, and hurriedly took pictures and samples.

"Can you figure out the height?"

The fat man nodded, selected four nearby blood drops, measured the longest and shortest values ​​of the burrs, and the diameter of the blood drop, and made a quick calculation.

"The height is between 1.2-1.28 meters.

Headed in this direction! "

Several people followed the fat man and headed southeast. After walking about 50 meters, the blood drops on the ground disappeared.

But a pile of ashes appeared directly, and several people were very excited. Zhou Hai picked up a few pieces of unburned knitted fabric in the ashes.

"It seems that these are the clothes of the deceased. Collect them."

At this time, there is no fear of blood drops, because several people looked up and saw another guardrail, which is far lower than the guardrail they came down from, and several people climbed up.

Standing on the road and looking at it, the investigators were surprised because they came to the east side of the expressway, which is also the west entrance of Bianjiazhuang, facing a spacious eight-lane road.

Looking at the cars whizzing by, Zhou Hai's eyes fell on a shop—Guodong Auto Repair Shop.

There are some maintenance tools scattered outside the door, and two large trucks are parked aside, and there are bursts of 'bang dang dang' sounds coming from the pavement.

Zhou Hai and the others quickly hid on the fork in the road leading to Bianjia Village. They stood there and looked again. Sure enough, the monitoring on the opposite side couldn't see this location, and the car repair department was blocked by a prominent gas station sign on the north side of it.

Without Zhou Hai's instructions, Da Li had already called Hu Squadron.

"Head, we found bloodstains and a pile of ashes at the first scene, followed the clues, went around to another exit, and the first thing we came up was the Guodong Auto Repair Department.

Do you see if you are moving or not? "

"Wait, we'll be there in 10 minutes!"

Upon hearing this, several people hurriedly hid their figures, and called the vehicle to inform the vehicle to turn quietly to the intersection on the west side of Bianjia Village.

A moment later the car arrived, and as soon as he got in the car, the fat man's cell phone vibrated.

It was Dr. Nan who called, and the fat man quickly answered the call.

"Fat Xu, you dare to answer the old man's call!"

"Hey old man, don't say you didn't get those photos, you lost your skills!"

"Cut, don't run on the old man. I know you are busy. I have already sent it to your mailbox. Next time, come and bring me good wine."

"No problem, Duping's Burning Knife will bring you five barrels!"

Before the other party could reply, the fat man had hung up the phone, heaved a sigh of relief, and clicked on the mailbox to check the picture. Sure enough, the pixels had improved a lot.

Da Li stretched his head by his side and leaned over. When he saw the third photo, Da Li slapped the seat.

"This is Cai Guodong!"

The fat man zoomed in on the photo, and a sturdy man with a black face appeared on the screen. He was raising his left arm to wipe the sweat off his head, but this movement was also blocking the camera.

There was a figure in a red dress in front of the picture, Zhou Hai suddenly thought of those knitted fabrics in the ashes just now.

Let the fat man zoom in on this position, and several people stare at the screen. Although the woman in the red dress is profiled, the fat man can recognize who it is at a glance.

"Yu Hongyu!"

Several people were very excited, such a discovery confirmed Cai Guodong's suspicion, and the rest depended on the results of the laboratory comparison.

Just thinking about it, a siren sounded from far to near.

Da Li poked his head and saw that it was Hu Squadron's car parked in front of Cai Guodong's door.

Zhou Hai's car also sped past.

Taking advantage of this spare time, the fat man has already told the madman and Xiao Liang what happened just now, their faces are all red, it is hot.

The police officers only wore police uniforms, and they also wore survey uniforms, hats and masks outside the police uniforms, which felt quite sour.

Cai Guodong, who was struggling for a while, was escorted out in handcuffs, and Zhou Hai, Fatty and others got out of the car carrying boxes.

Their vehicles didn't stop, they roared towards Duping City Bureau.

Zhou Hai and the others entered the car repair department, and Xiao Liang held up the camera to record the video.

The fat man observed for a while, then walked directly towards a tool box on the northernmost side. The fat man picked up a screwdriver with a black rubber handle, and at the same time held a small watering can in his hand towards the connection between the screwdriver shaft and the handle.

Zhou Hai knew that it was a luminol reagent [2]. Even if the murder weapon was cleaned, hemoglobin would remain on it, and the iron element in it would form a chemical reaction with the reagent, resulting in blue-purple fluorescence.

Sure enough, dots of blue-purple fluorescence flashed on the screwdriver, and the fat man quickly put the screwdriver into the transparent evidence bag.

Zhou Hai took it over and took a closer look, "The top of the screwdriver has some irregular depressions, which are the marks left by piercing the skull."

Just as Xiaoliang turned around, a toolbox behind him fell to the ground, the lock on it was broken, and the cover fell apart.

There was a hammer lying in it, and the fat man repeated his old tricks and continued to spray the luminol reagent. The blue-purple fluorescence was more obvious. After all, the wooden handle has tiny holes and it is not easy to clean it.

Zhou Hai squatted down and saw a mobile phone with a lot of rhinestones on the bottom of a toolbox, which was obviously a woman's mobile phone.

At this moment, Zhou Hai's phone rang, and it was Secretary Bian who called. Boss Yu found him. He was locked in the cellar of Cui Hong's house and had been dead for many days.

The lunatic got up, "I'll go and see!"

------

【1】Dripping bloodstains:
Blood drips vertically onto the ground or an object, forming round drops.

Its specific shape is different because of the height of the drop and the direction of motion.

If the blood falls from a height of less than 0.1 meters, the edge of the bloodstain is a complete circle;
When falling from a height of about 0.5 meters, the edges of the dots may have obvious jagged edges;

When falling from a height of more than 1 meter, not only can the edge of the dot be jagged, but there are often comma-shaped or linear small blood droplets around the dot.

If the blood is traveling on the injured person or dripping from a moving object (such as a vehicle), the bloodstain is oval in shape, with a star-like protrusion at one end, and the tip of the protrusion points in the direction of motion.

【2】Luminol (Luminol), also known as luminol.A blood that cannot be seen with the naked eye when detected at a crime scene can show a very small amount of blood (occult blood reaction).

The luminol reagent uses a reagent to identify blood. Even if the blood stain is wiped off, the hemoglobin in the blood will still remain. When the luminol reagent is sprayed on the hemoglobin, it will oxidize with active oxygen and release blue-purple fluorescence.Known as the luminol reaction.It is an organic substance used to identify blood.
