Chapter 787

"Woof woof!"

"Woof!"

After Da Zhuang barked twice, Er Zhuang followed with a bark. The tone of both dogs was one of dissatisfaction.

How could someone run to the police dog quarters to play with a sheep? And the sheep's name sounded particularly improper.

Of course, this didn't mean police dogs could be toyed with, or that they were allowed to be toyed with, but to come over and play with an alpaca instead of the police dogs? That was just too much!

Da Zhuang bared his teeth and ran forward a few steps, then stopped to watch, hesitating whether to go up and educate these two-legged creatures.

"Da Zhuang, come back!" Li Li put her hands on her hips and called her police dog back.

"Er Zhuang, you come back too!" Li Li shouted again, and Er Zhuang had no choice but to follow her back, looking dejected.

"Do you know you're police dogs? What are the requirements for being a police dog? Being a police dog is the same as being a police officer. You must pay attention to your appearance, be serious and earnest, protect the property and safety of the people, and protect yourselves... We've come to the city, so we must show the demeanor of well-behaved dogs from Ningtai County, understand?"

"Woof!"

"Woof woof!"

The two police dogs obediently responded in low voices.

"Brothers, I'll touch it first as a sign of respect, hahahaha..." A man who had taken off his shirt but was still wearing police trousers with a shiny seat rushed into the station of the Qianjin District Police Dog Squadron, laughing wildly.

Li Li looked closely and saw that the person rushing out was actually Shen Yaowei from Jiang Yuan's cold case task force.

He saw that his T-shirt was also wrinkled, as if he had slept through three or four night shifts, and his expression was as manic as if he hadn't slept at all. Immediately after, he threw himself directly onto the alfalfa pile...

Li Li covered Da Zhuang's eyes and whispered comfortingly: "We are good children, don't learn from them..."

Er Zhuang's eyes were not covered, and the whole dog had a shocked expression. He was a professional police dog born in a police dog base, the kind that had lined up to eat with a basin in his mouth since he was small. Although he quite liked interacting with two-legged creatures, when had he ever seen a two-legged creature hug an alpaca and rub it wildly?

"Time to eat." Jiang Yuan emerged from the kitchen in the back.

Even though they were at the Qianjin District Police Dog Squadron, Jiang Yuan still skillfully stir-fried a pot of Uncle Seventeen's fried rice, and at the same time made a pot of dog food.

The cost of the dog food was 100 times that of Uncle Seventeen's fried rice. When there were many people, the police force couldn't possibly provide such expensive food for humans; only police dogs were qualified to eat it.

Li Li led Da Zhuang to get the basin first. When she came back, she saw the police dogs of the Qianjin District Police Dog Squadron and Er Zhuang all lined up in a neat row, all obediently waiting to eat.

A little further ahead, Liu Jinghui, Lei Xin, Wu Junhao, and others were also seated at the long table, each with a basin of fried rice in front of them.

"Eat first." Jiang Yuan sat down, picked up his chopsticks, and greeted everyone.

The table was still set with some pickles, not violating the original intention of Uncle Seventeen's fried rice.

"This fried rice made by Jiang Yuan is inexplicably delicious." Wu Junhao shoveled a few mouthfuls wildly and sighed comfortably.

"It's my poor hospitality. Once the case is solved, I will definitely treat everyone to a big meal!" Lei Xin looked a little embarrassed.

Wu Junhao waved his hand: "Solving the case is the priority. Even if you treat us to good food now, we don't have time to eat. So, what's next? Should we continue the investigation or continue the inquiry?"

"The investigation needs a scope. We can't investigate aimlessly." Lei Xin couldn't even enjoy his meal and hurriedly said.

Liu Jinghui said "En" and said: "We must investigate first. The problem now is that the clue of the murder weapon has turned into a sketch, and it's hard to say how difficult this is."

Through the investigation into the source of the "thick-backed machete," which was the murder weapon, the task force finally locked onto a hardware store 1.5 kilometers away from the crime scene.

Hardware stores are allowed to sell knives, and some large hardware stores have quite a complete range of knives. This hardware store was of this type, doing both retail and wholesale, and also acted as an agent for some small brands. The thick-backed machete used as the murder weapon was the result of a bundled sale.

However, the internal surveillance of the hardware store was deleted every three days, so no footage was left.

The shopkeeper had some impression of the buyer, and Lei Xin excitedly invited a sketch artist to make a sketch of the killer—such plots often appear in American dramas, but in China, criminal sketches are not popular and their uses are not very extensive.

The Silver Case once used criminal investigation sketches, and the drawing was quite similar, but the criminal was still not caught because of it.

Jiang Yuan and the others were currently facing the same problem. Now that they had the sketch, what next?

Investigating according to the sketch is not only prone to errors but also easy to miss things.

As long as the killer knows that a search is being conducted downstairs, they can tidy themselves up a bit, and the sketch may become useless—the United States is a multi-ethnic country, and their criminal sketches include descriptions of skin color, long noses, wide noses, flat noses, small noses, etc. Relatively speaking, the differences in the appearance of Chinese people are too small, especially in small cities, where many descriptions in sketches are identical.

"Can we look for people by their feet?" Liu Jinghui put down his fried rice bowl, looked at the alpaca, and then at Jiang Yuan.

"There were no footprints at the scene; they were all destroyed." Jiang Yuan spread his hands and added: "The scene has already been surveyed. Even if I go to look for them now, I probably won't find anything as big as footprints."

"Then if we don't conduct a search..." Liu Jinghui looked at Lei Xin and added: "Then we'll have to try our luck."

"You say." Lei Xin could accept trying his luck. As a criminal police officer, who could solve a case with 100% certainty? In some cases, the killer doesn't even know how they came or went, and it's impossible for the police to guess their heart every time; that wouldn't make them a love expert.

Liu Jinghui slowly said: "When Jiang Yuan and I were in the car before, we actually had a guess, about what the killer's motive was..."

Liu Jinghui roughly recounted the conversation between the two and added: "Assuming the killer is indeed as we speculated, and the initial motive was rape... he didn't succeed in raping, so does he have other channels for venting?"

Several people were stunned. Liu Jinghui's angle was indeed beyond everyone's expectations.

There are many theories about rape, especially why the killer adopts such a means, and there are many different opinions.

Lei Xin thought for a while and said: "This time, in order to find Team Leader Jiang to work on the case, we have checked cases from a long time ago. In my impression, there are no similar cases of home-invasion rape."

"This just shows that he doesn't necessarily have a sexual fetish for home-invasion rape. From this perspective, this may also explain why he quickly turned from home-invasion rape to home-invasion murder after his attack was blocked." Liu Jinghui summarized and continued: "He went back to masturbate? Can that satisfy him?"

"Very difficult." Liu Wenkai had been shoveling rice just now, but when he heard this, he became focused and said: "He almost raped the mother and daughter together. After going back, he just masturbated? I don't believe it."

"What do you believe?"

"At least find a woman." Liu Wenkai's eyes lit up as he said: "He might have special requirements, for example, a threesome? Ordinary women won't cooperate with him; he can only find prostitutes."

Liu Jinghui coughed twice and said: "That's more or less what I meant, but not limited to this one type. There shouldn't be many prostitutes left in Qinghe City. Let's find as many as possible and ask them."
