Tianzhou City is the second largest city in the province, only slightly behind the provincial capital.
However, its economic developnt is much stronger than that of Haizhou, with a larger population.
Wang Changjiang is not unfamiliar with the Tianzhou City Criminal Investigation Team.
Over the past two decades, the Haizhou Criminal Investigation Team has often requested technical support from the Tianzhou City Criminal Investigation Team.
Wang Changjiang is also a classmate of Forensic Doctor Li Kai here, and they have exchanged professional insights.
In the past, when Wang Changjiang ca to Tianzhou City, he didn’t act overly submissive, but when asking for help, he naturally had to be modest.
Unlike now, where Li Kai is accompanying him with an extrely unnatural smile, while Wang Changjiang’s head is practically tilted up to the sky.
"Old Li, I rember your forensic laboratory equipnt is more complete than ours, and it’s all imported, right?"
Wang Changjiang smacked his lips in admiration: "We visited last ti and wanted to purchase them, but unfortunately, we couldn’t afford it."
Li Kai looked at his old classmate speechlessly: "Back then we asked you to join the Tianzhou Criminal Investigation Team, but you gave it up on your own."
Wang Changjiang glared at Li Kai with irritation: "Yuelan’s family is in Haizhou, how could I co to Tianzhou?"
Lu Chuan just followed along, saying little along the way.
He could tell that Li Kai and Wang Changjiang had a good relationship.
"You were just blinded by love."
Tsk!
Wang Changjiang gave a middle finger: "Co, let introduce to you our Haizhou Criminal Investigation Team’s cri scene investigator, Lu Chuan."
"He’s our tech expert, a specialist in skeleton identification."
Of course, Li Kai knew Lu Chuan; it was Zhang Yuanchao who recomnded Lu Chuan to assist them with the Skeleton Identification Analysis.
However, he didn’t expect Lu Chuan to be so young.
He looked just like a college student who had just graduated.
"Officer Lu is truly accomplished at a young age, receiving praise from Elder Zhang, who is the number one forensic doctor in the provincial departnt. You are the first in our province."
Lu Chuan smiled gently: "Forensic Doctor Li, you’re too kind, just call Lu."
"I rely have so research in skeleton identification, Forensic Doctor Zhang was being too generous."
Li Kai waved his hand: "Forensic Doctor Zhang worked at the Tianzhou City Criminal Investigation Team before. To earn his endorsent and be recomnded for our Skeleton Identification Analysis, Officer Lu must have more than just a bit of research."
Li Kai had obtained the Skeleton Identification Analysis report prepared by Lu Chuan through Li Changgeng at the provincial departnt’s Technical Identification Center.
Honestly, at that ti, he couldn’t believe that a person other than Zhang Yuanchao wrote the report.
Moreover, the other party wasn’t even a forensic doctor.
"Old Li, no need for pleasantries, let’s get to the case."
Wang Changjiang straightened his expression: "We’ve co with tasks this ti, and we must do our utmost to assist you."
"For all these years, the Tianzhou City Criminal Investigation Team has supported us, and this ti we can repay the favor a little bit."
The world of criminal investigation is one united, not to ntion technical exchanges, cross-region apprehensions are common.
Spending days and nights in the car staking out is sothing every criminal detective has done.
Therefore, as long as they can manage, no team says no to support.
Discussing the case, Li Kai’s expression also turned serious: "The skeleton was discovered yesterday afternoon during a highway expansion, dug up by an excavator."
"The skeleton is in the autopsy room; we have completed the skeletal reconstruction but have not found any obvious issues."
While introducing, Li Kai led Lu Chuan and Wang Changjiang to the autopsy room.
On the steel autopsy table laid a skeleton.
Lu Chuan put on three layers of gloves and bent over to observe the skeleton carefully.
"Was it crushed?"
Though the skeleton had been restored, both ends of the sternum were broken and collapsed, making it impossible for the thoracic cavity to support itself.
Li Kai nodded: "We have conducted carbon decay analysis on the skeleton, determining that the burial ti should be at least fifteen years ago, coinciding with when the highway was built."
"We suspect that the deceased was buried first and then run over by a road roller during the road-paving process."
Lu Chuan circled the body for a detailed observation: "Has the identity been confird?"
Li Kai shook his head: "We extracted DNA information from the bone tissue and compared it to the missing persons database, but without success."
"So, we want to determine so physical characteristics of the skeleton’s owner through the Skeleton Identification Analysis to see if we can confirm an identity."
After a simple survey, Lu Chuan toured the forensic laboratory of the Tianzhou City Criminal Investigation Team.
To be honest, Lu Chuan was quite stunned.
Just as Wang Changjiang said, the Tianzhou City Criminal Investigation Team... is wealthy!
Looking at the equipnt in this room, spectrum analyzers, automatic bone density detectors, bone age carbon decay analyzers, and frequency variable laser scanners...
With these tools, Lu Chuan could cut the skeleton identification analysis ti in half.
Li Kai proudly introduced the various functions and prices of the instrunts.
A mix of pride and embarrassnt showed in his expression: "We have a lot of equipnt and know how to use it, but our ability to do comprehensive analysis is lacking."
"When we encounter such cases, we have to request support from higher-ups."
After familiarizing himself with the equipnt, Lu Chuan began a ticulous analysis of the skeleton.
First was the cleaning of the skeleton.
Because it had been buried, the skeleton was contaminated with so soil.
Before performing the Skeleton Identification Analysis, Lu Chuan had to thoroughly clean all the skeleton.
At the sa ti, the soil removed also needed soil quality testing.
Lu Chuan pulled a small brush from the cri scene investigation box and carefully cleaned the skeleton.
Of course, this small brush wasn’t an LV brand brush.
It was a pig-bristle brush, with hard bristles suitable for cleaning dirt.
This task, although tedious, was done solely by Lu Chuan without letting anyone help.
Every detail needed to be observed by Lu Chuan himself.
"The pubic symphysis... angle... less than seventy degrees, determining the gender of the skeleton as male."
The male sacrum is long and narrow, with the angle of the pubic symphysis between sixty to seventy degrees.
The female sacrum is short and wide, with the angle of the pubic symphysis between ninety to one hundred degrees.
Of course, these basic determinations had already been completed by Li Kai and his team.
"Carbon analysis of bone age, determining the bone age is fifty-six years."
"Observation analysis of the bone rings, the age at ti of death was... forty years."
Age assessnt, considering so other situations as well.
For example, osteophyte formations on the hip bones.
In adults, osteophyte formations generally occur after the age of thirty, and the hip bone tends to exhibit more growth.
At the ti of death, the age was forty years, and if the skeleton existed for fifty-six years, it ans the deceased died sixteen years ago.
"The ankles have fossil-like encrustations, the deceased had gout while alive..."
"Bone length... one ter seventy-six, pre-death height plus flesh thickness... around one ter seventy-eight."
Human bones are shorter than pre-death height due to the absence of flesh, skin thickness, and joint fasciae.
And once skeletonized, these parts disappear.
"Bone density combined with height analysis: the deceased weighed eighty kilograms, bone density was two percent lower than average, combined with age analysis... the deceased enjoyed affluent living conditions... and lacked regular exercise."
"The tip of the coccyx worn down more than usual... the deceased had a sedentary lifestyle previously..."
This skeleton identification analysis demonstrated the strength of Lu Chuan’s interdiate skeleton identification analysis skills completely.
Because the skeleton was relatively intact, the information about life before death was far more comprehensive than analysis perford at the hotpot restaurant case by Lu Chuan.
"As for the cause of death..."
Lu Chuan picked up two ribs and carefully compared them.
