It seems that we did not come in vain this time, and the salesman made inquiries and determined that this DR diamond ring was sold by this store.

"When was this diamond ring purchased? Who is the purchaser? I immediately asked.

My two questions were very direct and very pointed. After hearing this, the smile on the salesman's face began to freeze a little, and was replaced by a somewhat embarrassed smile: "Sorry sir, this is the customer's privacy, I can't provide it to you, I'm very sorry." ”

I first nodded, indicating that I understood her difficulties, and then I took out my police ID from my pocket and said seriously: "I am Qin Mu, a criminal police officer from the Ningzhou Public Security Bureau, and I need to investigate the relevant information of this diamond ring." ”

After seeing the police ID, the salesman was obviously stunned for a moment.

The salesman pondered for a moment and whispered, "Please come with me, two of you." ”

We followed her to the very end of the counter by the wall, where she pulled out a laptop and pulled up all the information about the ring.

"This diamond ring is a diamond engagement ring, not a wedding ring, and it was purchased a month ago. The buyer is called Ma Junxu, and the giver is called Zhang Mengyu. The salesman said seriously.

"What about the price?" I nodded and asked.

"This is the WITH YOU series of lifelong marriage proposal rings, the diamond is 100 points D color, that is, one carat, and the purchase price is 145,919 yuan." The salesman said to us.

"A diamond ring of nearly 150,000 yuan, this Ma Junxu is generous." I muttered, and then continued to ask: "Call up the identity information of Ma Junxu and Zhang Mengyu to show me." ”

Because the purchase of DR diamond rings needs to be bound to identity information, it is necessary to use an ID card.

I got the identity information and contact information of Ma Junxu and Zhang Mengyu, and immediately sent this information to Lin Zifan, asking him to determine whether the deceased in this case was Zhang Mengyu as soon as possible. At the same time, let him investigate Ma Junxu's personal identity information and social relations, and be able to spend a lot of money to buy a marriage proposal ring, which shows that he is deeply in love with Zhang Mengyu, and it also shows that his family is very wealthy.

"Did they come after they bought the diamond ring?" I asked again.

The salesman shook his head and denied, "I haven't been here again." ”

"Okay, if they come back, be sure to contact us in time." I said seriously.

The salesman nodded confusedly, and we left the DR shop.

"It's strange that such an expensive diamond ring was left at the scene of the crime." I looked at the diamond ring in my hand and still felt very puzzled.

"Maybe the murderer was more panicked and hurried at the time, after all, it was in the woods at night, and there was still heavy rain at that time." Li Meng said lightly.

I took a deep breath and said in a deep voice, "Let's go back to the bureau first." ”

Returning to the office of the Serious Crime Team, Lin Zifan immediately brought us good news: "Team Qin, the identity of the deceased has been confirmed, it is Zhang Mengyu." ”

"Have you notified the family to identify the body?" I asked in a deep voice.

"The family has been contacted, but they will not be able to confirm it until the autopsy is complete." Lin Zifan said seriously.

I nodded, and then asked, "Have you contacted Ma Junxu?" ”

"I've got in touch too, he'll be over in a moment." Lin Zifan said lightly.

Now, I can finally breathe a long sigh of relief, because this case finally has clues, and now as long as the identity of the deceased is determined, we have a lot of investigation directions.

I sat in my chair, and my hanging heart was finally half gone.

After a while, I settled down and asked again: "Has Zhang Mengyu and Ma Junxu's personal information been investigated?" ”

"It's been investigated." Lin Zifan said in a deep voice.

"So fast?!" I looked at him with some shock.

Lin Zifan smiled and said to me: "These are thanks to our almighty internal system of the Public Security Bureau, but what I have found so far is not comprehensive, and many things still need to be investigated, but I have handed over the identity information of the two people to the criminal police team, and they will investigate." ”

I nodded, and quickly said, "Tell me about the information you have so far." ”

"The deceased Zhang Mengyu, 29 years old this year, from other provinces, graduated from key undergraduate colleges, and after graduation, she entered the top 500 enterprises in my country, but she worked for three years and resigned.

Ma Junxu, twenty-nine years old this year, and Zhang Mengyu are fellow villagers, graduated from ordinary colleges, and after graduation, he started his own business and founded an audiobook studio, which is the predecessor of the current popular Listening Pavilion APP. ”

Lin Zifan seriously told us about the relevant clues he had investigated so far.

"Zhang Mengyu is twenty-nine years old?!"

Li Menghu frowned, and was very surprised, because judging from the appearance of the corpse, Zhang Mengyu was a little girl in her early twenties.

I was also a little shocked by this, but what shocked me even more was that this Ma Junxu turned out to be the owner of the Suitingge.

Listening Pavilion is one of the most popular audiobook apps at the moment, all works are free and without any advertising implantation, it is a very easy to use software, and many people around me are using this APP.

This also proves that this Ma Junxu is now worth a very high value, and it is a piece of cake to spend 150,000 yuan to buy an engagement ring.

At the same time, it also shows that this Ma Junxu and Zhang Mengyu are now lovers.

"Any other clues?" I pondered for a moment and asked again.

Lin Zifan shook his head, spread his hands and said, "No, these are public information that can be found on the internal website of the public security system." ”

I nodded, habitually holding my fingertips to my temples and lost in thought.

Zhang Mengyu, Ma Junxu's fiancée, was killed last night in the woods at the foot of Beishan Mountain in Ningzhou City.

Suburbs, woods, transport, blood moon, heavy rain......

Vendetta, love killing, random killing, passion killing......

What's the connection?

"When is Ma Junxu coming?" I steadied myself and asked earnestly.

"Fifteen minutes ago, he said he was driving here, he should be there soon." Lin Zifan said lightly.

As soon as he finished speaking, my phone rang.

A name was displayed on the screen of the mobile phone: Officer Liu of the Traffic Police Detachment.

This police officer Liu, when I was still in the criminal police team three years ago, investigated a traffic accident case and had contact with him. I had a phone number on my hand at the time, but we have barely been in touch since then, so what is he calling me for?

"Hey, I'm Qin Mu." After I answered the phone, I said lightly.

"Hello? I'm from the traffic police team, are you looking for someone named Ma Junxu? ”
