"After the identification of the size of the wound of the deceased, the tool used to drill holes in the deceased's body should be this type, a 600022 log with a copper handle. Pen "Fun" Pavilion www.biquge.info"

Officer Wu picked up a brand new awl from the table.

"We went to a shop in Taofang Village and bought it from a shop in Taofang Village, and it's a tool that is very common in the market, and you can buy it in hardware stores and supermarkets.

Uses include drilling, shoe repair, etc., and can also be used as a spare tool at home.

The deceased's wound was not stained with rust, indicating that the crime tool was used regularly before being used to commit the crime, or it was a newly purchased awl. ”

Hearing the words "not long after the new purchase", Lu Ran's mind moved: "If it is really a new purchase, then, who bought it?"

Xu Hao followed Lu Ran's question and replied: "Although there are many places that sell awls, but since the deceased are all residents of Taofang Village, we speculate that the murderer should be someone from this neighborhood, or someone who has crossed paths with these three people.

So we first checked all the hardware stores in Taofang Village.

Taofang Village is not big, and there are not many hardware stores, there are five in total.

Look at all of their sales records and ask them what they think of the customers who came to buy the awls......"

Halfway through Xu Hao's description, Lu Ran remembered something again, so he interrupted: "Wait, let me sort it out." Earlier, Officer Wu said that the perpetrator was wearing gloves throughout the whole process, so he probably didn't leave any fingerprints, right? That's why he started with the tools used to commit the crime.

However, there is another point, did the perpetrator leave any other traces, such as blood, body fluids......"

Lu Ran didn't finish speaking.

Yuan Yi did not shy away from following his words and said, "You are asking, did the perpetrator do any sexual assault on the deceased?"

Lu Ran nodded: "Well, because you said earlier that the deceased were all women, and they were all naked, you guessed that this was a case of sexual assault and then silence." ”

Yuan Yi replied to him with a smile: "You are thinking in the right direction. However, the medical examiner did not find any other person's blood or bodily fluids. In other words, the perpetrators did not leave bodily fluids on them.

And he was very careful, he didn't panic, and he didn't hurt himself. ”

"This ......"

But even so, it cannot be ruled out that the perpetrator's motivation was to satisfy sexual needs. It is possible that the perpetrator's sexual behavior does not require physical contact with the woman, or that he has an abnormal psychosexual gratification pattern. ”

Lu Ran nodded, Yuan Yi was right, even if there were no traces left on the deceased's body, it could not prove that the motive of the perpetrator had nothing to do with sex.

"But...... What happened next showed us something else. Maybe this incident really has nothing to do with sexual assault. ”

Unexpectedly, Yuan Yi suddenly changed her words, as if she wanted to deny her judgment just now.

Lu Ran was a little puzzled.

"What do you mean, what's going on?"

Xu Hao continued with the words that were interrupted by Lu Ran just now: "After we investigated the hardware store in Taofang Village, we gained something in the hardware store closest to Li Li's house.

The girl in Li Li's family once came to the store and bought an awl, and the model was also matched.

What's more, after investigation, this girl is a little special. ”

"Girl?" Hearing this title, Lu Ran was a little strange.

"Well, the name of the locals, or rather, the name of the girl. The girl's name is Wang Lei, sixteen years old, and she is the adopted daughter of Li Li and her husband Wang Deshun.

According to the owner of the hardware store, the girl was a child bride-in-law bought by Wang Deshun's family. ”

"Child daughter-in-law?" called one title after another, making Lu Ran feel as if he had returned to China before the revolutionary years. "How can there be such a thing as a child bride now?"

"About this, we asked Wang Deshun, and he admitted that Wang Lei was his adopted daughter, but he did not admit that Wang Lei was bought by him with money, and also said that there was no such thing as a child daughter-in-law.

Wang Deshun worked as a shoemaker in his early years, and he began to be a carpenter these years, and he is sixty years old this year.

He also has a son who has suffered from paralysis since he was a child, and he has been lying at home for a long time. ”

Officer Wu explained specifically.

"What does Wang Deshun do at home? Wang Lei went to buy that awl, could it be for the adults in the family?" Lu Ran asked.

"Hmm. That's what I thought too. So I'm going to ask him about that awl. ”

Speaking of this, the corners of Officer Wu's mouth raised a slight arc, "Interestingly, when I mentioned in front of him that his daughter Wang Lei had bought a new awl a few months ago, a light suddenly flashed in his chaotic eyes, and the cigarette in his hand stopped there, did not move for a long time, and then, unconsciously confided out a sentence from his mouth: 'Could it be her ......'"

"Could it be him?" Lu Ran thought for a while, and then said, "What do you mean, she? That girl, Wang Lei, his father, is suspicious of his daughter?"

Officer Wu nodded affirmatively.

"We also investigated several neighbors in the surrounding area. Officer Cheng said: "But they said that they didn't know much about it, only that they often heard the sound of family members beating and scolding their youngest daughter Wang Lei."

Also, the statement of the child daughter-in-law may be true, the Wang family has always been very busy recently, and the neighbors have not seen Wang Lei for a long time.

If nothing happened to the Wang family, they were probably preparing for a happy event. ”

"Scolding, child daughter-in-law, and father's suspicion...... Could it be that this girl is revenge? Could it be that she really did it?"

Yuan Yi looked at Lu Ran and said, "She has bought the same type of awl, and she has enough motive to commit the crime." ”

"So, is it true?" This result was really unexpected by Lu Ran.

Officer Wu shook his head and said, "We searched his house that day, but we didn't find the tool she used to commit the crime. I don't know if she hid it in advance.

Instead, I found a lot of red ornaments and bedding, which were indeed used in the village to prepare for happy occasions. ”

"What about the girl?"

"Brought it. ”

"Came to the bureau?Teacher Yuan, have you seen it?" Lu Ran asked Yuan Yi.

"Well, I did. ”

"How?"

She said she hadn't done it. Officer Wu replied to Lu Ran, but his brows furrowed.

"Even if she did it, she wouldn't admit it, shouldn't she change her strategy?" Lu Ran said.

"She's not lying. Yuan Yi's face was serious, and he said in an affirmative tone.

Lu Ran looked at Yuan Yi, and originally wanted to ask again, are you sure, but remembering her ability to watch the six ways and listen to the eight directions in class, she gave up in an instant.

She's probably a living polygraph.

Without waiting for Lu Ran to speak, Yuan Yi looked at him and added, "I'm sure." ”

"Okay. Lu Ran saw it again, "So, this matter has nothing to do with her?"

"Can't say that. Yuan Yi became uncertain at this moment: "I think she has something to hide." ”

"Is there anything she's hiding, murderer?"

"Not sure, just I think she should be able to say more, but she won't speak. ”

"Won't speak?"

"Well, I think she's going to need a little more time, and now that you're here, maybe you can ask her. ”
