Chapter 139 - 139 135 Very Reasonable
139: Chapter 135 Very Reasonable 139: Chapter 135 Very Reasonable “Are you sure it’s the killer’s blood?” Hou Xiaoyong had already taken off his gloves and pulled out his phone.
The squadron leader didn’t deserve to be woken up over the sequence of the crime scene, but if the killer’s blood was found without notifying the squadron leader, then get ready to be chastised.
Jiang Yuan glanced sideways at Hou Xiaoyong and once again downgraded him.
For a technical investigator to say something so unprofessional, rating him LV0.8 was really overestimating him, and it was unfair to other technicians in Longli County.
He, Jiang Yuan, was not like the “vampire forensic doctor” who could lick a bloodstain and then read off the killer’s ID number, blood type, hobbies, sexual orientation…
Actually, even a vampire forensic doctor couldn’t do that because Europeans don’t have ID numbers.
Jiang Yuan frankly stated:
“All I can say is, this bloodstain is quite unique, and there is a high possibility it belongs to the killer or an eyewitness.
It could also be the victim Zhang Hong’s blood.
We’ll know after a DNA test.
Bloodstain DNA testing should be quick.”
Ordinary DNA might take several hours to process, but using bloodstains and blood scabs for DNA can be directly amplified, and results can come out in three to four hours.
Hou Xiaoyong, rated as an LV0.6 technical investigator, slapped his forehead, said “You’re right,” and hurriedly called the squadron leader.
“Let’s continue,” Jiang Yuan had little interest in the police captain of Longli County.
He was just a workhorse borrowed from the next county, who hadn’t fed on any prime fodder, nor had anyone play music for him while massaging; he just did what a workhorse should do.
Currying favor with the production team’s leadership was not a workhorse’s job.
Of course, the local workhorses of Longli County still cared very much about the production team’s leadership; they became very enthusiastic and actively involved in the work.
“We’ll scan this area now,” Jiang Yuan continued as if reconstructing the scene.
Using a single bloodstain alone was still not very reliable.
Moreover, theoretically speaking, if there is one bloodstain, the probability of there being another from the killer is relatively high—Jiang Yuan believed that the bloodstain found just now should belong to the killer.
There were no signs of a third person at the scene, so a bloodstain that was not from the victim naturally could be the perpetrator’s.
As for the origin of the perpetrator’s blood, Jiang Yuan first guessed that it was likely that the perpetrator began by using his own fists.
Using one’s own body to strike the other is a more venting form of expression than using a weapon.
It’s just a bit rough on the hands.
Unscathed fists in movies belong to the handsome guys; the not-so-handsome ones tend to hurt their hands when hitting people.
Fists are harder than cheeks, referring to the bones, not the skin.
Jiang Yuan kept looking and recording wave after wave.
By then, the technicians from Longli County were starting to grow dissatisfied.
Once again, Hou Xiaoyong, chosen by the group, suggested, “Forensic Jiang, since we’ve found someone else’s bloodstain, shouldn’t the following inspections be more meticulous?”
“Okay,” Jiang Yuan agreed.
Then, picking up another item, Jiang Yuan quickly made a record, waving his hand to start the next batch.
Hou Xiaoyong reminded him, “Shouldn’t you look again?”
“Look…
at what?” Jiang Yuan asked Hou Xiaoyong in return.
Hou Xiaoyong carefully said, “I was just thinking…
from my understanding, shouldn’t a longer observation time increase the chances of discovering something?”
“The thought isn’t wrong,” Jiang Yuan looked deeply at Hou Xiaoyong, now rated as an LV0.5 technical investigator, and said, “Come with me.”
Hou Xiaoyong looked back; the technicians who had egged him on all turned their heads away.
Hou Xiaoyong cursed them silently for being unreliable and could only follow Jiang Yuan to the object they had just revealed.
“What can we deduce from this cast-off blood pattern?” Jiang Yuan asked Hou Xiaoyong.
Hou Xiaoyong was stunned for a moment, then whispered, “Didn’t we just discuss this…
”
“We’ve discussed that it could be caused by a blunt object, right?” Jiang Yuan coaxed.
Hou Xiaoyong nodded.
Jiang Yuan continued, “Besides being caused by a blunt object, what else could there be?”
Hou Xiaoyong didn’t answer, and Jiang Yuan patiently waited for him.
It wasn’t bad for a workhorse to get a break once in a while.
Hou Xiaoyong, hoping for the squadron leader to come and see him working hard, could only rack his brains and say, “It can also indicate the strength used.”
“What else?” Jiang Yuan asked with a smile.
“This…
I don’t quite remember,” Hou Xiaoyong admitted.
“It can indicate a left or right preference,” Jiang Yuan said softly.
“Right, right, so the killer is right-handed,” Hou Xiaoyong nodded vigorously, uttering a professional term and sighing with relief.
“Hmm, and looking at the shapes of these bloodstains, what can we deduce?” Jiang Yuan persisted.
Hou Xiaoyong then froze again, like a computer that had crashed.
What could he deduce?
Whatever he could’ve deduced he had already returned to his teachers.
More questions?
Jiang Yuan then explained in detail:
“First, you need to focus on the size of the bloodstain because blood droplets of different weights will be thrown at different distances…”
“Secondly, and this is why I particularly pay attention to cast-off bloodstains, it’s because within the cast-off patterns, one can often find the perpetrator’s blood.
Think about why that might be?”
“Right, it’s because the perpetrator’s hand was bleeding.
When moving, it’s easier to create blood spatter, which is also why I asked you to pay attention to the pattern…”
Under Jiang Yuan’s instruction, Hou Xiaoyong’s eyes gradually began to glaze over.
He was never a good student keen on learning, let alone the fact that Jiang Yuan had just unloaded so much information in one go…
it was overwhelming.
Finally, Jiang Yuan paused to take a sip of water to moisten his throat.
Then, looking at the conch shell in his hand, he said, “We’ve been looking at this bloodstain for quite some time now, it should be considered meticulous.”
“Meticulous, indeed,” Hou Xiaoyong quickly nodded, then shuffled his feet and said as he walked away, “I’m going to see if Captain Hou has arrived yet…”
He realized that he had misspoken earlier and was subjected to an outpouring of information from Doctor Jiang, which he had to passively accept.
Yet he seemed to have no upper hand over Jiang Yuan, and could only endure it.
Compared to being praised by Captain Hou, studying was far more terrifying.
Never mind.
Dawn was breaking.
Captain Hou Le of Longli County’s Criminal Police had just arrived.
“Sorry, so sorry.” Without entering the crime scene, Hou Lejia stayed outside, shaking hands with Jiang Yuan repeatedly, then engaged warmly in small talk.
Jiang Yuan’s hand was gently squeezed and lightly shaken—might as well take it as a wrist exercise.
The pleasantries concluded.
Hou Lejia then said, “The bloodstains that Forensic Jiang Yuan…
I mean, that you examined last night have been rushed to Qinghe City.
We’ll probably hear back soon.
How about we grab something to eat while we wait for the results?”
“Sure,” Jiang Yuan replied without reservation.
Although the crime scene hadn’t been completely processed, with the current manpower, it would take a week to finish given the site’s size.
Police officers still need to live.
Hou Lejia and the others understood as well, previously not minding the heavy workload as it wasn’t their jurisdiction; now, realizing how efficient Jiang Yuan was, Hou Lejia had outgrown his initial narrow-mindedness of a one-time use mindset.
“Get that restaurant owner to deliver a few portions of the pork intestines and stomach chicken over here.” Hou Lejia summoned Hou Xiaoyong and gave the instructions with care.
Hou Xiaoyong followed orders confidently.
Everyone feels self-assured when doing what they’re good at.
The pork intestines and stomach chicken were delivered steaming hot in a clay pot.
The restaurant owner seemed adept at business, arriving personally on an electric tricycle, bringing foldable tables and chairs, as well as utensils, along with him.
They set up the tables and chairs on the street, a few dozen meters away from the yard, by the side of another fried rice food cart, and placed the clay pot with the pork intestines and stomach chicken in the center, surrounded by dipping sauces.
Pork stomach chicken is already a renowned dish, with the pork stomach creating delicious broth and the chicken soup being equally savory.
Sprinkled with a generous amount of black pepper, the blend of flavors combined with a deliciously spicy aroma makes it a worthy match for any dish alone.
The only drawback to the pork stomach chicken as a standalone dish might be its texture.
But with the addition of pork intestines, this downside is instantly alleviated.
As the lid of the pot is lifted.
The rich aroma wafts out.
Everyone’s stomachs start to grumble.
Casting off their uniform tops and sitting around the pot in their sleek, shiny dress pants, they gathered.
Hou Lejia lifted a cup of tea and said with a smile, “We’re in humble conditions today, so allow me to substitute tea for wine in thanking Forensic Jiang Yuan…”
Jiang Yuan stood up with his cup, took a small sip in cooperation, and then focused on eating his meal, appearing every bit the reticent technician he was.
Jiang Yuan knew that his mentor, Master Wu Jun, only got to enjoy a few canteen meals with the city’s forensic team; he should not expect more, just focus on doing his job well.
However, Hou Lejia was showcasing his ability to schmooze, amiably building rapport, talking about how great his relationship with “Crocodile” was, sharing amusing stories that happened between the two counties, and then expressing gratitude for Jiang Yuan’s assistance.
If there had been alcohol on the table, Hou Lejia might have been able to sweet-talk Jiang Yuan completely.
Once Jiang Yuan had eaten his fill, he promptly brought up the case and said, “Captain Hou, I think I can wrap up with the bloodstains here in a bit.
I’ll rest for a while, then I’d like to help my mentor with the autopsies.”
Hou Lejia was slightly surprised, “You can finish that quickly?”
“The items for DNA might take a week or two to clean up, but I don’t think it’s that significant anymore,” Jiang Yuan replied bluntly.
Hearing this, Hou Lejia came to understand that Jiang Yuan was choosing his tasks, thinking what if this was his own technician…
Oh, but he isn’t their technician.
Hou Lejia pondered for a few seconds, then realized it wasn’t a bad thing after all—after all, Jiang Yuan had identified a distinctive piece of scabbed blood.
Changing his tone, Hou Lejia said, “The autopsies should be all done, no issues there, which is why we need to focus on breaking through from the scene of the crime…”
“Let me first review the autopsy reports and report back to my mentor,” Jiang Yuan said, still eating his tripe and never lifting his head.
Those present understood Jiang Yuan’s stance: If you want to give unreasonable commands, I’ll walk away.
Hou Xiaoyong shifted in his seat, suddenly feeling a bit gleeful.
Since Captain Hou was reprimanded too, it felt much more justified and normal that he himself had been reprimanded.
Hou Lejia sensed Jiang Yuan’s dissatisfaction in his words but swiftly smacked his own head, “Look at my memory, my poor brain, always thinking of useless stuff.
You haven’t even done an autopsy with your mentor yet since you got here.
Let’s get that arranged right away.”
