Solve the case and become stronger

Xicheng District.

Zijin Road.

A police car pulled into a small road and then slowly pulled up in front of a two-story self-built house.

The houses are surrounded by high brick walls, and at the gate of the courtyard, two police officers have set up a cordon.

The car door opened, and Jiang Yi and Yan Jun got out of the car together.

"Strict team!".

The police officer at the door saluted Yan Jun.

"Where is the site?".

Yan Jun asked.

"In the kitchen at the back of the house. "

The officer replied.

Yan Jun bowed slightly at them, and then crossed the cordon with Jiang Yi, through the courtyard to the kitchen at the back of the house.

The kitchen is also a self-built bungalow, the outside is not painted, but simply smoothed with cement, and the police officers of the investigation team are busy going in and out of the kitchen door.

Yan Jun and Jiang Yi walked into the scene together, and the police officers inside greeted Yan Jun one after another.

On the floor next to the kitchen stove, a female corpse collapsed in a pool of blood, her throat slashed by a sharp object, and the wound was deep and bone-piercing, which was shocking.

Like the previous case, the female corpse's mouth was also painted like a clown's mouth, which was even a little funny at first glance, but the surrounding police officers all looked solemn and solemn.

Su Yan has already carried out the corresponding autopsy work in front of the corpse, she is wearing a mask and a simple ponytail, but she still can't hide her cold temperament, and a wisp of green silk hangs down on her forehead, adding a bit of charm.

"Tell me a brief debrief on the scene. "

Yan Jun ordered at the police officer on the side.

"Not long ago, we received a call from a nearby police station, claiming that a body of a 'clown mouth' similar to the previous case was found here. "

The police officer said: "According to the police report of the traffic police, the deceased's name is Yan Chunyu, Chinese New Year's Eve two years old today, married, the first witness is her husband Qin Fei, the nearby market rushed to the market that day, Qin Fei went out early in the morning, and when he returned home, he found that his wife had been killed, so he called the police as soon as possible." "

"Where is Qin Fei now?".

Yan Jun asked.

"With our officers, take the corresponding notes in the next room, but it should be almost done. "

The officer replied.

"After a while, the transcript is done, let him come here. "

Yan Jun said.

"Understood!".

The officer responded immediately.

Jiang Yi scanned around the kitchen where the crime occurred.

"It's a suburb, it's a remote environment, and there are few houses nearby, and there are all kinds of trees to hide, which is really very suitable for the murderer's choice of where to commit the crime. "

Jiang Yi began to analyze: "There are two doors in the kitchen at the scene, but maybe it's a matter of habit, both doors are open, so after the murderer sneaked into the courtyard, he went directly to the kitchen without any effort and killed the deceased Yan Chunyu." "

"The deceased Yan Chunyu was not delicate, judging from the traces at the scene, she also fought with the murderer, and the fight was very intense. "

Jiang Yi put on gloves and picked up a kitchen knife on the ground, which had blunt marks in several places.

"The deceased tried to resist with a kitchen knife at the first time, but the murderer's skills were specially trained, so after the deceased struggled for a while, he was quickly subdued and killed. "

Jiang Yi said: "In the process of fighting for uniforms, the two kicked the bucket behind them, causing the road leading to the front door to be wet, so if the murderer leaves through the front door, he will definitely leave footprints, according to the murderer's usual cautious character, he will never make such a simple mistake, so he must have left through the back door." "

"But as we have just observed, the back door is only a few dozen centimeters away from the fence, and the exits on the left and right sides are all blocked by debris. "

The police officer on the side said: "According to the husband of the deceased, because they can't use the back door to enter and exit on weekdays, they will open the back door for ventilation when cooking, so they pile some miscellaneous items there." "

"That's exactly the details I'm going to talk about. "

Jiang Yi said: "Because both sides of the back door are blocked, it is impossible for the deceased to forcibly push away the debris and leave, so it is easier to leave more detailed clues, so there is only one way for the murderer to leave - that is, to climb over the wall." "

Hearing this, the police officers present were all dazzled, and at the same time couldn't help but look at the fence on the side.

"The fence behind the kitchen is about two meters high, and a normal adult can climb over it. "

Jiang Yi said: "Go and check the wall, maybe you can find clues like footprints." "

The police officers glanced at Jiang Yi with some admiration, and after getting along for a while, they had completely recognized this young policeman in his early twenties from the bottom of their hearts.

Yan Jun on the side gave an order, and the police officers came to the fence to investigate.

On the other side, Su Yan also got up from the corpse, took off the mask on her face, and said: "The time of death of the deceased was six hours ago, that is, around half past nine in the morning, and there were multiple contusions on his body, which should have been left during the fight with the murderer." "

"The fatal wound was also in the neck, and the throat was cut with a knife, and the technique of cutting the throat was very similar. "

Su Yan said: "But I carefully examined the wound of the deceased and found that it seemed to be slightly different from the previous case. "

"Could it be that the murderer changed the murder weapon?"

Yan Jun raised his eyebrows.

"Yes or no. "

Su Yan said: "The shape of the murder weapons in the two murder cases is basically the same, but the only difference is the size and length of the murder weapon, the length of the murder weapon in this murder case is longer than that of the previous murder weapon, and the arc of the tip of the knife is larger, and the blade is also sharper." "

"Could it be that the murderer has remade and polished a larger dagger murder weapon, so as to facilitate and better commit crimes?"

Yan Jun also frowned and thought about this question, "Or is his last murder weapon missing?"
