Things that solve crimes

The rising sun is rising in the east, and the warm sunshine falls through the dense leaves, turning into golden spots.

Qin Henian dressed neatly and left the room.

In the morning light, a big rooster with a red crest and colorful feathers strode over with its head held high, croaking "oh, oh, oh, oh" to the sun.

Looking at the impressive big rooster, Qin Henian touched his chin, looked at the boss beside him and asked, "Can this rooster be eaten?"

As if he understood Qin Henian's words, the big rooster rushed towards him with an "ooh, oh, oh" sound.

Looking at the curved mouth with a sharp light, Qin Henian ran away suddenly.

The boss quickly ran over and hugged the big rooster, and said with a smile, "If you want to eat it, I'll catch another one." Don't even think about this one.

"Okay, catch another one." Qin Henian didn't have to eat this one.

The boss let go of his hand, the big rooster "swished" twice, flew to the tree, and looked at Qin Henian condescendingly, his eyes were quite "disdainful".

Qin Henian raised his eyebrows, why is this big rooster so arrogant? In time for tomorrow, he bought it from his boss, took it home and stewed it!

When Xu Xia gets up, the chicken is still stewing. The stewing time for an old chicken is not short.

Smelling the aroma of chicken soup, Xu Xia said, "It's so good to eat so early in the morning."

"The chicken is still stewing, but there are chicken offal." Qin Henian pushed the plate with chicken offal in front of Xu Xia.

"Chicken offal is not bad either."

……

After the meal, the two tidied up briefly and waited for the guide, auxiliary criminal police from the local police station and forest police to arrive before starting to enter the mountain.

There were local people leading the way, so Jiang Yuan walked a little more easily. As he walked, he said, "I thought it was just the two of us."

Xu Xia walked and said, "Although there are no clues about the case, there is still necessary support. Otherwise, how can we find it if we are strangers to each other?"

Qin Henian was speechless. As far as the current situation of this case is concerned, the municipal bureau has taken it seriously. Most of the time, if the provincial department or the municipal bureau wants to express concern, it will send about two police officers to the local area, like they did this time , with the support of the forest police from the police station, it has been taken seriously.

"What about the extraction of trace evidence?" Qin Henian asked unwillingly.

Trace evidence identification is a new method of criminal investigation that has emerged in recent years. It refers to tiny material materials or traces that can prove a crime.

The examination of trace evidence requires physical or chemical analysis with the help of scientific instruments to determine the molecular characteristics, chemical composition or appearance of the material.

There are extremely many types of trace evidence, which vary depending on the nature of the case, the scene environment, the professional status of the criminal and the victim, etc., such as seeds, pollen, sawdust, hair, feathers, scales, fibers, paint, glass, grease, ink, Cement, cosmetics, drugs, etc. Through the identification of trace physical evidence, its source can be determined, the crime process and the characteristics of the criminal can be revealed, thereby providing evidence for investigation and solving the case.

Xu Xia sighed, "The body is very clean. I can't find anything else if I look for it."

"Then where should we start looking now?" Qin Henian asked.

Xu Xia took out a map, whispered a few words to the forest police, then took out a pen and circled a few places, "Look for these places first."

Qin Henian looked over and saw that Xu Xia had circled ravines, caves and other places where it was easier to hide corpses.

"We can all think of these places. Do you think the murderer will choose these places?" Qin Henian put forward a different opinion.

"It's easier to hide corpses in virgin forests. A few more police dogs will be more useful than us." Qin Henian continued.
