Things that solve crimes

After getting the news he wanted, Xiang Hong left the prison.

At the door, Qin Henian and Cao Xuewu were waiting for news in the car. Xiang Hong came out and got in the car. Cao Xuewu quickly asked, "How is it?"

Xiang Hong clenched his fist and said, "I've confessed, I've confessed everything."

"Have you also confessed the arson case?" Cao Xuewu asked again.

Xiang Hong's smile faded, "Wu Ke instigated He Zhi to admit the arson case."

Qin Henian frowned, "Why did Wu Ke want He Zhi to admit it? Could it be that he was responsible for the serial arson case?"

"If you look at it from this aspect, Wu Ke is very suspicious."

"But the evidence still needs to be found."

"I've brought the information for everyone to take a look at." Xiang Hong took out a stack of information from the black briefcase beside him.

The three of them each took part of the information and started reading.

"What's going on with this burnt bone china piece?"

"Let me see"

Xiang Hong leaned his head over and Qin Henian pointed at a few words, eight pieces of burnt bone china.

"Well, let me think about it," Xiang Hong recalled carefully, "After the first arson incident, the property management of Wanyuan Community in Nancheng discovered four large burnt bones abandoned on the roadside during daily patrols. , after identification, suspected human bones were found.”

"The property management personnel immediately chose to call the police. At that time, there were many onlookers, and the incident spread quickly, causing a certain impact."

"After the police arrived at the scene, the scene had been damaged. Afterwards, the police sent people to search the entire Wanyuan community and found four more bones in the trash can."

"After forensic identification, it was confirmed that three of the bones were human sternum bone fragments and five were human thigh bone fragments."

"There was just an arson case on the front foot, and the burned bones appeared on the back foot. It is difficult not to connect the two cases. But..."

When Xiang Hong smiled bitterly at this point, both of them understood what he was saying and there was no evidence.

Xiang Hong sighed, "The owner of the bone fragments was not found out, and no remains of the bones were found at the arson scene."

"This was not found in the two subsequent arson cases, so the two cases were not investigated together."

"Go back to the bureau first and look at the bones." Qin Henian said.

The other two people did not object, so the three returned to the bureau.

……

There is a big difference between burned bones and fresh bones.

Fresh bones are normal in color and have a certain luster, and the spinal cord cavity and spinal cord are plump and shiny.

Burnt bones are different. A healthy person may be milky white or pure white, while the bones of a patient with advanced cancer are red.

In addition, if the person took a lot of drugs during his lifetime, then the person's bones may be green.

If you are poisoned, the bones will be black. If you take medicine that makes the body contain too much phosphorus, the bones will be pink.

When the bones are burned until they become porcelain, it also means that the organic matter on the bones has been burned away. It also means that the commonly used DNA technology has become ineffective.

The bone fragment Qin Henian is holding in his hand is exactly this kind of bone fragment that has been burned to the point of porcelain.

The curvature of the bone surface has disappeared, and there are still a few small bone fragments attached to the bone. At first glance, it does not look like bones, but looks a bit like a weird piece of art.

As a forensic doctor, Qin Henian could naturally discover that this was a piece of porcelain leg bone.

Seeing that he could not find any useful information, Qin Henian put the first bone fragment into the evidence box and took out the second one.
