"Bones are very difficult things to deal with, and if the conditions are not too bad, bones can be preserved for thousands of years. Lin Lei's eyes narrowed slightly, and he said lightly.

As Lin Lei said, in ancient tombs, everything about the corpse disappeared, but often the bones remained. Whether it is thousands of years or even hundreds of thousands of years, it is possible to preserve them perfectly - for example, the ape-man skulls found by archaeologists are still intact after hundreds of thousands of years.

"Detective Lin, you said that the flesh and blood part of Alice's corpse can be disposed of by biological methods, but the bones are obviously not eaten by any animal!" Sergeant Henry frowned and said in a deep voice.

Lin Lei bowed slightly, the light in his eyes flashed, and he quickly set his eyes on Sergeant Henry, and said slowly: "Sergeant Henry, if I remember correctly, when I came in just now, Mr. Claude seemed to be holding a cup of coffee?"

Claude was already limp and speechless. Sergeant Henry glanced at Claude, then nodded and said, "Yes, Claude was drinking coffee at the time. ”

Drinking coffee?

What does this have to do with the case?

Sergeant Henry's face was full of doubts, feeling that his brain cells were completely insufficient, and he couldn't keep up with Detective Lin's "divergent" thinking......

Lin Lei was about to speak, but saw Qiao Yan smile slightly, and said, "BOSS, I understand!"

Lin Lei was stunned, turned his head to look at Qiao Yan, and asked with a smile, "Uh, what do you understand?"

"The secret of coffee. Qiao Yan blurted out.

Lin Lei smiled knowingly and was silent.

Between smart people, sometimes it is very tiring to get along, and sometimes it is easy to get along.

When there is intrigue, it is very tiring;

When the heart is clear, it's very relaxed.

Lin Lei is naturally a smart person, or a very smart person, and Qiao Yan is not far behind.

Seeing that Detective Lin and Forensic Doctor Joe had a dumb riddle, Sheriff Henry felt a little unhappy, but how dare he show half a point?

Sergeant Henry smiled awkwardly and asked Lin Lei, "Detective Lin, you said that Claude drinks coffee...... What the hell happened to the coffee?"

Before Lin Lei could speak, Qiao Yan looked at Lin Lei and said softly, "BOSS, will I explain or will you come?"

Lin Lei thought for a moment and said lightly: "It's better for me to come." ”

Qiao Yan nodded and said no more.

Lin Lei thought about it, suddenly smiled, glanced at Sheriff Henry meaningfully, and said slowly: "Sergeant Henry, sometimes when I am at the scene of solving a crime, I like to tell a little story to mediate the tense atmosphere at the scene. ”

Sergeant Henry was not familiar with Lin Lei, but after Inspector Jim said that Detective Lin came to "guide" to solve the case, he hurriedly googled and checked Lin Lei's information.

Of course, the people of the United States don't use Baidu, they only use Google.

There are all kinds of information on Google, and many of them are uploaded from the side of the book - in the book, the media industry calls Lin Lei "the king of routines at the scene of the crime", Lin Lei loves to tell stories, which Sheriff Henry can be regarded as finding on the Internet.

So Sergeant Henry smiled, nodded and said, "Detective Lin, you say, I'll listen." ”

Lin Lei sorted out his thoughts and began to recite an ancient poem, the beginning and end of which were: "I have broken his bones and raised his ashes again." has been mistaken all his life, and he hates it...... It is to raise ashes and crush their bones, and to destroy their corpses with ashes. The corpses are gone, and I will not keep the bones or ashes!"

Lin Lei first chanted in Chinese, and then simply paraphrased in English - the ancient text is vast and profound, and it is almost impossible to translate into English, only paraphrased.

When Lin Lei finished translating, he went on to explain: "This poem "Frustrating Bones and Raising Ashes" is a poem written by Wang Jingwei, a notorious traitor in China. Although Wang Jingwei's character is inferior, I have to admit that his literary literacy is still relatively high. ”

After a pause, Lin Lei continued: "This kind of way of destroying corpses and destroying traces is not uncommon, and there is an idiom in Huaxia that is specially used to describe it - breaking bones and scattering ashes. ”

"I see!" Sergeant Henry was not stupid, although he couldn't understand the ancient Chinese text that Lin Lei had recited before, he understood the content of Lin Lei's translation.

When Lin Lei said the words "crush bones and scatter ashes", Sheriff Henry finally knew Claude's method of destroying bones.

That's right, it's a bruising of bones and ashes!

Then Lin Lei continued to explain: "Sergeant Henry, I personally like to drink coffee, so I also have a certain understanding of coffee. To put it simply, there are two types of coffee, one is the powdered coffee in bags or fills, and the other is the coffee beans, which need to be ground into powder form by a special grinder. ”

After a pause, Lin Lei's eyes narrowed slightly, and he said, "If my guess is correct, Mr. Claude drinks ground coffee." As for the coffee grinder, Mr. Claude's house naturally has it, and it must be the one that is very expensive. ”

"Someone, go and search!Make sure you find Claude's coffee grinder!" Sergeant Henry ordered, and his men immediately went to a group of people and rushed into Claude's house.

"Fresh bones are not suitable for grinding with a grinder, they have to be overheated. I think Claude must have burned Alice's bones in the fireplace, and when the bones had loosened up, they broke them down into small pieces and then grinded them. If you don't talk about other parts, let's talk about skulls, if they don't burn them, they are difficult to break with knives. Lin Lei continued his reasoning.

Sergeant Henry nodded his head in understanding.

Indeed, as Lin Lei said, the chemical composition of bones is mainly phosphorus and calcium, which are very hard if not treated. But after the fire, the bones become very brittle and are easily processed into small pieces and then ground.

"Well, I had previously examined Claude's fireplace in detail, and found no remains of the corpse...... Why is that?" asked Sergeant Henry, somewhat puzzled.

Lin Lei explained: "If the body is burned, of course there will be all kinds of residual materials. However, if only the bones are burned, there is very little residue. If the bones are sealed in a large pot and burned, there will be no traces. Claude's purpose in burning bones is not to burn them to ashes, but to make them loose by heating them for a long time, so that they can be easily handled......"

As soon as Lin Lei explained this, Sheriff Henry understood that this was the case.

Sure enough, the police soon found a large coffee grinder from Claude's house. Because there was still a lot of coffee powder in the grinder, the police were not suspicious when they checked before, so they simply ignored it.

The ground bone meal, presumably disposed of by Claude in the sewers or in the garbage, was not as noticeable as the corpse parts.

Now, if you take the grinder back to the police station for a closer inspection, you can definitely find the remnants of human bone meal - this bone meal has been processed by technical means, and it may be possible to find DNA.

Even if no DNA can be found, it can certainly prove that bone meal belongs to humans.

Next, there is an important piece of physical evidence.

That's the fish tank.

In the fish tank, DNA residues can definitely be found.

Soon, the police found a large fish tank from the basement of Claude's house. The fish tank was empty, but Lin Lei was not worried at all, there would definitely be evidence of Alice's DNA on it.

So far, all the puzzles of Claude's wife murder case have been solved by Lin Lei.

Claude was already so frightened that he couldn't speak......

Just as Lin Lei was about to leave, Qiao Yan suddenly said to Sheriff Henry, "Well, Sheriff Henry, I want to tell you something very interesting. ”

Sheriff Henry hurriedly said, "What's the matter?"

Qiao Yan's face was solemn, and she seemed to recall a piece of history: "The traitor Wang Jingwei, the author of the poem "Frustrating Bones and Raising Ashes" that Lin Lei said earlier, still regarded himself as a student of Sun Yat-sen before he died, and he only wished to find a treasure of feng shui in the Plum Blossom Ridge of the Purple Mountain and sleep next to the prime minister. His wish was finally fulfilled in November 1944. A year and two months later, the then Nationalist army was ordered to destroy his tomb. In the name of testing artillery, they used 150 kilograms of TNT explosives to blow up the cement, took out Wang Jingwei's coffin, sent it directly to the crematorium, and pushed it into the crematorium together with the coffin of Shanghao Nanmu. Dozens of minutes later, people and trees were ashes. The commander of the national army ordered the blower to be turned on and blown towards the hearth - Wang Jingwei, the author of "Breaking the Bones and Raising the Ashes", himself was also in ashes. ”

When Sheriff Henry heard this, he was silent, and he didn't know what to say......
