"The most famous of them, the Mercury Light Sapphire, was exhibited at the Fusubi auction house twenty years ago after it disappeared, and the auction price at that time was 340 million US dollars.

Su Tong raised the photo in his hand, the appearance of the two gems in the photo, due to the age, can no longer find a high-definition picture. But you can vaguely see the outline, one of which is very much like the emerald in Lu Qihua's list of belongings.

"Did the robbers really come and go like in the movies?" Chen Hui was hooked up by this legendary case and wanted to gossip, and he hurriedly snatched the photo from Su Tong's hand to see.

"The jewelry thief was committed by two people, they were mixed with armed bodyguards, and they didn't show their facial features until they suddenly attacked, and the people present reacted.

At that time, the exhibitors were famous and noble families from all over the world, and these two gems were exhibited by a large British family, and after the theft of these two gems, it almost caused a vicious diplomatic war between the two countries, and the influence was great. ”

Sun Ju said slowly, he was only one or two years old back then, but he also knew something.

Su Tong nodded and motioned to He Xingchen to open the data on the computer.

"One of the two jewelry thieves was injured in the lower leg by a bodyguard, but in the end the two robbers escaped, so a blood sample was left at the scene." Su Tong then finished talking about the following information.

The computer screen displayed the archival materials at that time, which were written in great detail, and the social news page of the time was also attached to it, indicating that this case was indeed a sensation at that time.

"So, one of the jewelry thieves of the year was Lu Qihua's father?" Li Hua pointed his chin with his index finger and guessed.

"Yes, judging from the analysis of the genetic map left behind back then, even if they are not immediate relatives, they are definitely related by blood. At that time, the technology was not very developed, but the most basic map analysis was still very accurate. Su Tong said with some regret.

At the same time, the screen of the computer screen switched to the genetic analysis map at that time, the older one was owned by the jewelry thief who left the blood stains from the shooting, and the lower one was the blood sample obtained from Lu Qihua's body, the arrangement of the two genes and the distribution of chromosomes were almost identical.

"According to the information from my previous investigation, "Yuan Fang, who had been silent, spoke," Lu Qihua is Chinese, and since he returned from Europe at the age of eighteen, he has been living in China for a long time, and even got married and had children.

Everyone knows that Lu Qihua is a rich second generation, but no one knows what kind of business his family is doing abroad, but because Lu Qihua is very low-key and very generous to his classmates and friends, no one has ever doubted the origin of this money. ”

There is no doubt that the reason why Lu Qihua is so rich is that it is very likely that the jewelry thief's father sold the jewelry after he emigrated abroad.

"Are all of Lu Qihua's official documents credible?" Sun Ju looked at Yuan Fang and asked, are these people not suspicious of Lu Qihua's identity at all?

"When Lu Qihua was born, Europe was still relatively chaotic, basically it can be said that as long as you have money, even if you are a black immigrant, you can become a citizen of your country, so..."

"If I'm not mistaken, it seems that Lu Tingkang, who is also a Chinese who came back from Europe, is not only a partner with Lu Qihua from childhood to adulthood, but also a partner in his career." Xu Sa said meaningfully.

"Could it be that Lu Tingkang is the descendant of another jewelry thief?" Li Hua patted Chen Hui's shoulder excitedly and guessed boldly.

"We can only suspect now, after all, only one of the robbers had left blood, and after so much time has passed since the case, it is estimated that the two thieves are now dead. The official identities of Lu Qihua and Lu Tingkang, we have no evidence to prove that they are fake. Su Tong closed the folder in his hand. After analyzing the surveillance footage before, we believe that Lu Tingkang had no credible alibi evidence on the night of the crime, plus the origin of this family's background. I'm sure that Lu Qihua's death is definitely related to this Lu Tingkang, but we haven't found evidence to link all this. ”

There was a dead silence in the office, Su Tong and Xu Sa looked at each other, and finally did not speak again.

"Isn't that gem missing? I suspect it was Lu Tingkang who took it. Chen Hui suddenly said this.

"How?" Sun Ju saw that someone finally spoke, and couldn't help but encourage Chen Hui to continue.

"We found several sets of fingerprints on the doorknob of the safe at the scene of the crime, which were from the deceased Lu Qihua, the deceased's wife, and Zhuang Siqiang, who is now locked up." Chen Hui said as he extracted the trace inspection report from the scene.

"It's normal, the deceased couple may have touched the safe, and Zhuang Siqiang also stole a lot of jewelry inside." Li Hua looked at Chen Hui's movements and said with some disapproval.

"That means the safe was opened by the deceased himself," Chen Hui had already found the inspection report.

"The trace inspection found no traces of missing fingerprints on the doorknob, indicating that after the death of the deceased couple and his wife, only Zhuang Siqiang touched the safe door. But when Zhuang Siqiang went to the scene of the crime, the safe had been opened, and the gem was not inside. ”

The report listed three sets of fingerprints, Lu Qihua and his wife's fingerprints were missing, only the last group of Zhuang Siqiang's fingerprints was the most complete, which was also the evidence that Yuan Fangli pointed out that Zhuang Siqiang was the murderer.

"An ordinary person, how could he casually open his safe full of jewels and not close it, I guess it should be Lu Tingkang who came to Lu Qihua's house, pretended to say something to make Lu Qihua voluntarily open the safe, and killed him and took away the gems while Lu Qihua was not paying attention." Chen Hui sorted out his thoughts little by little.

Xu Sa nodded approvingly, and Sun Ju also nodded, thinking that this explanation was indeed reasonable.

"But what about the motive for the killing?" Zhou Li asked questions that they had not answered all along.

"Let's assume that the descendants of the jewelry thieves of the year are Lu Qihua and Lu Tingkang, but it doesn't make sense? It doesn't make sense that they didn't rob it before, but now they come to rob it? Zhou Li couldn't figure out what Lu Tingkang's motive for killing wanted to kill Lu Qihua's family of three.
