Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 43 The Sleeping Bones

Tianzhou City is the second largest city in the province, only slightly worse than the provincial capital.

But it is much stronger than Haizhou's economic development and has a larger population.

Wang Changjiang is no stranger to the Tianzhou Criminal Investigation Detachment.

In the past two decades, the Haizhou Criminal Investigation Detachment has repeatedly requested technical support from the Tianzhou Criminal Investigation Detachment.

Wang Changjiang and the forensic doctor Li Kai here are classmates again, and they have also exchanged and studied professionally.

However, when Wang Changjiang came to Tianzhou City in the past, he didn't say he was low-key, but he must have a low profile when asking for help.

Unlike now, with Li Kai by his side, his smile was extremely unnatural, and Wang Changjiang's head almost went up to the sky.

"Old Li, I remember that the equipment in your forensic laboratory is more complete than ours, and they are all imported."

Wang Changjiang clicked his tongue: "We visited last time and wanted to buy it, but unfortunately we couldn't afford it."

Li Kai looked at his old classmate speechlessly: "You were asked to come to the Tianzhou Criminal Investigation Detachment back then, but you gave up on your own."

Wang Changjiang glared at Li Kai angrily: "Yuelan's family is in Haizhou, can I come to Tianzhou?"

Lu Chuan just followed, not saying much along the way.

He could tell that Li Kai and Wang Changjiang had a good relationship.

"You were dazzled by love."

cut!
Wang Changjiang gestured with a middle finger: "Come here, let me introduce you to Lu Chuan, the current investigation criminal policeman of our Haizhou Criminal Investigation Detachment."

"This is our technical leader, an expert in bone identification."

Of course Li Kai knew about Lu Chuan, and it was Lu Chuan who Zhang Yuanchao recommended to help them with the identification and analysis of the bones.

However, he did not expect that Lu Chuan was so young.

Looks like a recent college graduate.

"Officer Lu is really young and promising. You are the first one in our province to be praised by Mr. Zhang, the No. 1 forensic doctor of the provincial department."

Lu Chuan's smile was very gentle: "Forensic Li, you are welcome, just call me Xiao Lu."

"I just did a little research on bone identification, and Zhang Yuanchao, the forensic doctor, praised it."

Li Kai waved his hand: "Forensic doctor Zhang Yuanchao once worked in the Criminal Investigation Detachment of Tianzhou City. To get his approval and recommend to help us with the identification and analysis of the bones, the police officer Lu does not have a little research."

Li Kai got the bone identification analysis report made by Lu Chuan through Li Changgeng of the Technical Appraisal Center of the Provincial Department.

To be honest, he didn't believe at all that this was an appraisal made by someone other than Zhang Yuanchao.

What's more, the other party is not even a forensic doctor.

"Old Li, don't be polite, let's talk about the case first."

Wang Changjiang's expression straightened: "We came here with a mission this time, and we must do our best to assist you."

"For so many years, we have been supported by the Criminal Investigation Detachment of Tianzhou City. This time, it can be regarded as our small return of favor."

Tianxia Criminal Investigation is a family, not to mention technical exchanges, arrests across regions are common.

A criminal policeman of any detachment has done it before when he stays in the car for several days and nights.

Therefore, for things like support, as long as you are busy, there is no saying no.

Speaking of the case, Li Kai's expression also became serious: "The skeleton was discovered yesterday afternoon when an excavator was dug out during the reconstruction and expansion of a highway."

"The skeleton is in the dissection room. We have completed the restoration of the skeleton, but no obvious problems have been found."

While introducing, Li Kai brought Lu Chuan and Wang Changjiang to the dissection room.

A skeleton lay flat on the steel dissecting table.

Lu Chuan put on three layers of gloves and attached himself to carefully observe the condition of the skeleton.

"Been crushed?"

Although the skeleton had been restored, the two ends of the sternum were broken and collapsed, and the entire chest cavity could no longer support it.

Li Kai nodded: "We have conducted a carbon decay analysis on the bones and determined that the bones should be buried at least 15 years ago, which happened to be the time when the highway was built."

"We suspect that the deceased should have been buried first, and then crushed by a road roller during the process of compacting the road surface."

Lu Chuan observed carefully around the corpse: "Is the identity confirmed?"

Li Kai shook his head: "We extracted the DNA information from the bone and compared it with the database of missing persons, but it was unsuccessful."

"So, we want to determine some physical characteristics of the owner of the skeleton through the identification and analysis of the skeleton, and see if we can confirm the identity."

After a simple survey, Lu Chuan visited the forensic laboratory of the Tianzhou Criminal Investigation Detachment.

To be honest, Lu Chuan was shocked.

As Wang Changjiang said, the Tianzhou City Criminal Investigation Detachment... has money!
Take a look at the equipment in this room, spectrum analyzer, bone density automatic detector, bone age carbon attenuation analyzer, and frequency conversion laser scanner...

With these things, Lu Chuan can shorten the time for bone identification and analysis by half.

Li Kai introduced the functions and prices of various instruments with some pride.

The expression on his face was mixed with pride and shame: "There are a lot of things, and we all use them, but the ability to do comprehensive analysis is not good."

"When you encounter this kind of case, you can only ask for support from above."

After learning about the equipment, Lu Chuan continued to analyze the skeleton in detail.

First up is the bone cleanup.

Because they had been buried, the bones were stained with some mud.

Before doing the bone identification, Lu Chuan had to clean up all the bones.

At the same time, the cleaned soil should also be tested for soil quality.

Now he took out a small brush from the survey box, and Lu Chuan cleaned up the bones carefully.

Of course, this small brush is not a LV brand brush.

It is a brush made of pig hair. The bristles are hard and suitable for cleaning dirt.

Although this work was cumbersome, Lu Chuan didn't ask anyone to help.

Any details must be observed by Lu Chuan.

"The pubic symphysis...the angle...is less than seventy degrees, and the sex of the skeleton is determined to be male."

The male sacrum is long and narrow, and the angle of the pubic symphysis is between sixty and seventy degrees.

The female sacrum is short and wide, and the angle of the pubic symphysis is between ninety degrees and one hundred degrees.

Of course, Li Kai and the others have already made these basic judgments.

"Bone age carbon detection and analysis, the bone age is determined to be 56 years."

"Observation and analysis of the bone wheel, the age of the deceased at the time of death was... 40 years old."

In judging his age, Lu Chuan also integrated some other factors.

Such as hip osteophytes.

After the age of 30, adult bones generally have growths, and the growth of growths at the hip bone will be more.

The time of death was 40 years old, and the skeleton existed for 56 years, which means that the deceased died 16 years ago.

"There are fossil-like encrustations on the feet and ankles. The deceased suffered from gout during his lifetime..."

"The length of the bones...1.7 meters six, the height before death plus the thickness of the flesh...1.7 meters eight."

The height of human bones is shorter than the height before life. In addition to the thickness of the flesh and blood of the feet and the thickness of the scalp, the fascia in the joints also has thickness.

After the bones are turned into bones, these things will disappear.

"Bone density combined with height analysis: the deceased weighed [-] kilograms, and his bone density was two percentage points lower than the average level. Combined with age analysis...the deceased's living conditions were superior...long-term lack of exercise."

"The average level of the tip of the tailbone is more serious than the average person...the deceased had been sedentary for a long time before his death..."

In this bone identification analysis, Lu Chuan fully demonstrated the strength of the intermediate bone identification and analysis skills.

Because the bones are more complete, the information about the deceased is far more comprehensive than Lu Chuan's analysis of the hot pot restaurant bones.

"As for the cause of death..."

Lu Chuan picked up two sternums and compared them carefully.
