Cri Scene Investigation Laboratory.
Shen Yan was visiting Lu Chuan’s work from the past six days.
"Are these what you cultivated?"
The laboratory now had more than fifty petri dishes arranged on the table.
So of them seed empty, with nothing inside.
In so, flies were buzzing, and in others, there were fly larvae crawling.
Lu Chuan nodded: "There’s one more experint that’s not finished, results should be out by tomorrow morning."
"It’s just that..."
"What’s wrong?"
Even though Shen Yan was a Forensic Doctor and had studied the basic theory of forensic entomology.
This was her first ti seeing soone like Lu Chuan raise and cultivate fly larvae using petri dishes.
Lu Chuan shook his head: "Through this cultivation of fly larvae, we can more accurately determine the timing of the first batch of flies that infested the body."
"However, from the current results, so things don’t seem logical, these eggs seem to have taken too long to hatch, as if..."
Lu Chuan opened one of the petri dishes, inside was a pupa, a larva about to hatch.
"As if they had been refrigerated for a period of ti!"
While cultivating the fly larvae, Lu Chuan discovered a strange phenonon.
The generational relationship of these fly larvae was very simple, with all being first-generation larvae.
In other words, there was no phenonon of flies that erged on the body laying eggs again.
This posed a problem.
Lu Chuan collected DNA information from the fly larvae gathered.
He found so larvae shared homologous DNA, aning they ca from the sa fly.
But their developnt was different; so were large, and so were small.
This is not common among parasites on bodies.
Unless in closed conditions, flies would typically find a body within a few minutes of death.
This ans the ti of egg-laying by flies almost equals the ti of death.
That’s a key reason for the importance of forensic entomology.
However, the homologous larvae found on this body showed a vast developntal gap.
The first batch Lu Chuan cultivated had pupated and turned into flies two days ago.
But the smaller larvae were only over a centiter long, with a week or so until pupation.
Lu Chuan was now waiting for an interdiate result, which would allow him to determine the exact timing.
With several larvae currently pupating, analyzing their pupation ti could uncover vital information.
Shen Yan didn’t understand this field too well; she only knew so basic theoretical knowledge.
"I heard my ntor say that Team Leader Ren Qiang and Team Leader Sun Jun faced so difficulties?"
Lu Chuan nodded; he had heard as well.
"Brother Hui and his team found the first site where the body was dumped early the day after the cri. I went to do the Cri Scene Investigation."
"But there were very few traces left on site, as heavy rain had washed everything away. There were only signs suggesting the body had been dragged, and a shoe left behind."
"So hair samples we collected were confird to be the victim’s, but beyond that, there were no significant findings."
"Group Leader Sun’s team conducted a careful investigation based on your discovery that the clothing size of the victim didn’t match their body."
"They’re currently holding a cri analysis eting, likely reporting the situation."
"However, earlier this morning, I heard from Group Leader Sun that the outlook wasn’t very optimistic."
Lu Chuan and Shen Yan arrived early this morning.
On their way to the office, they bumped into Sun Jun, chatted briefly, but didn’t delve into specifics.
The only thing they knew was the search for that expensive piece of lingerie had hit a snag.
eting Room.
"Is it possible to contact the headquarters of the lingerie company and check the nationwide consur information for this specific piece?"
Since it’s been confird that in Haizhou City there’s no issue with people purchasing this model and size of bra, they should expand the search nationwide.
Given that only thirteen pieces were sold in Haizhou City, the national quantity shouldn’t be particularly large either.
Besides, not all cities have sales outlets for this luxury store.
So investigating it shouldn’t be too difficult.
"I’ll give it a try, the company’s headquarters isn’t located in Haizhou. I’ll get in touch with the Criminal Investigation Team on their side to see if they can assist."
Sun Jun had actually thought of this thod too, but he was unsure if it would succeed.
However, it’s hard to say if they’ll find anything because this lingerie wasn’t sold under real-na registration.
The reason the Haizhou City Criminal Investigation Team conducted such a thorough check was that this is their jurisdiction.
But despite this, it took a week to get clarity.
If this scope were expanded nationwide...
Sun Jun had little confidence.
In the past, they’d had similar experiences, and they invariably failed.
Qin Yong actually understood this situation too.
He worked his way up from the front line and had encountered similar cases where the investigational scope had to be expanded.
But success in those situations was rare, though the challenge didn’t an they should abandon the search.
Of all the current clues, this one was the most apparent, and they couldn’t let it go.
Of course, Sun Jun and others can’t rely solely on a bra to pinpoint the killer.
After all, even if they identify all individuals who bought this D-cup bra, they can’t simply accuse the person who lost theirs of being the murderer.
Otherwise, Sun Jun needn’t have led a team of over twenty people checking around Haizhou for a week.
The eting concluded quickly.
Cri Scene Investigation Office.
"How is it, any progress?"
Old Bai handed Liu Guodong a cup of hot tea, inquiring about the cri analysis eting that just concluded.
Liu Guodong shook his head.
"Ren Qiang’s team has checked all the surrounding villages and found no missing persons or witnesses; the place where the perpetrator dumped the body was too remote, not even visited by fishern."
Old Bai could understand that.
If not even fishern visit the place, it’s indeed a desolate area.
"What about Sun Jun’s side?"
"Nothing either; the thirteen people who purchased that D-cup bra in Haizhou City have been thoroughly investigated, and nothing was discovered."
"Old Qin plans to extend the search nationwide to see if there are any leads for the bra."
Nationwide?
Old Bai shook his head upon hearing that.
Over the years, talk of nationwide investigations was nothing more than just talk.
A single life doesn’t warrant the mobilization of national resources.
Moreover, Cri Scene Investigation had examined that bra.
There were no distinctive substances, no hair, nothing found on it.
So skin flakes were found, but they belonged to the deceased.
"I think they still need to focus on the surrounding area first; the perpetrator couldn’t have dumped the body without a trace. Though it’s remote, it can’t be completely deserted, right?"
Yang Sen believed they should start from the scene.
"It’s not like you haven’t been to the scene; no one lives nearby, Ren Qiang’s team has been checking for almost a week there, and found nothing either?"
