Old Bai adjusted the reading glasses on his nose.
In total, there are nine vehicles; six of them are refrigerated transport trucks, which are large and not easy to maneuver. If Zhao Wenjun really wanted to transport a body silently, these vehicles would obviously be unsuitable.
The remaining vehicles include two sedans and one SUV.
"The SUV, President Zhao usually drives this one; he rarely drives the others."
"Alright, take us to have a look."
The SUV Wang Bei ntioned is a rugged off-road vehicle, and it has been modified.
The car is parked in the parking lot of Jiuding Fruit Market.
"Lu, let’s start with this vehicle."
Lu Chuan nodded. On this trip, he was there to work. Old Bai was leading, and wherever he was told to clean, he would clean.
Collecting and analyzing trace evidence from a vehicle is extrely ti and energy-consuming.
Lu Chuan had done similar work before, like with tires.
The mud and gravel on the tires can to so extent reveal where the vehicle has been, what surfaces it has driven over, or even when it went there.
A bit of dust on the wheel arch can determine when the vehicle was washed and where it has been.
Of course, this ti, Lu Chuan’s focus in trace evidence collection is not on analyzing where the vehicle has been.
Even if Zhao Wenjun used this vehicle to transport a body, over a month has passed, making it difficult to determine whether this vehicle has been to the cri scene based on the residues.
This ti, Lu Chuan’s focus in trace evidence testing is the vehicle’s interior space, to see if any biological traces of Chen Lili can be found.
First, fingerprints. When the UV light was turned on, the steering wheel, door handles, and seats were covered in fingerprints.
Extracting so many fingerprints is truly ti-consuming.
But there’s no choice; the key to collecting trace evidence is ticulousness.
Not just fingerprints, even a few micrograms of soil cannot be overlooked.
"Does anyone other than Zhao Wenjun drive this vehicle?"
Wang Bei shook his head, "Of course not, this is President Zhao’s exclusive vehicle; it’s worth hundreds of thousands. We usually just drive two sedans."
Wang Bei pointed to the side, at a black Accord and a Jetta.
While Lu Chuan was collecting trace evidence, Old Bai was chatting with Wang Bei.
This kind of work, Old Bai really couldn’t help with; not only was his technique lacking, but his eyesight was failing too.
These past two years, Old Bai had to wear reading glasses even to read books, and his eyesight was worsening year by year.
"Let’s go, have a look over there."
"Alright, alright, I’ll go get the keys."
Although the appearance of both sedans looked fine, at one glance, Old Bai could tell that they were old models.
"Bought second-hand?"
"Both are second-hand," Wang Bei nodded, "the Jetta was bought three years ago, and the Accord was bought last year."
"Really?"
Old Bai approached the black Accord, showing great interest, "Looks good, how much did you buy it for?"
"Just over 130,000, not expensive."
"Mmm, indeed not expensive. I thought about buying one too, just couldn’t find a suitable one."
Old Bai opened the rear car door, "The space in this Accord isn’t bad; it’s well-maintained even as a second-hand car."
"It is indeed nice. After buying it last year, I only drove it twice."
"You only drove it twice?"
"Who usually drives it then?"
"Wu, the newbie who joined in September, I heard he is a university graduate who couldn’t find a job."
"Oh, that’s quite unfortunate..."
Old Bai walked around to the trunk, opened the trunk door, "This trunk space is also quite large, suitable for ho use."
As he spoke, Old Bai haphazardly opened the trunk’s cover plates and glanced around.
"By the way, is that Wu your driver?"
"Not exactly; after he ca, he didn’t seem to do much work. He had a good relationship with Boss Zhao and just kept driving this car. But later, he resigned, probably just last month."
Resigned?
"What day last month?"
"The second, just the second."
"Do you know why he resigned?"
"No idea, he just suddenly stopped coming. The boss said he resigned."
"What’s this Wu’s na?"
"Wu Rui, his na is Wu Rui."
Old Bai pondered for a while and returned to the SUV.
Lu Chuan was crouching, wiping the fingerprints off the passenger door.
"Lu, leave that for now. Co check this out."
Old Bai lifted the right cover plate of the trunk and pointed to a spot in the corner, "Look at this, does it look like?"
Although Old Bai didn’t say what it looked like, Lu Chuan could understand what he ant.
Upon closer inspection, using a UV lamp, a soil-brown stain was very conspicuous.
A flash of excitent crossed Old Bai’s face, as if he had stumbled across it effortlessly.
"It should be, right?!"
Lu Chuan nodded in confirmation to Old Bai’s mumblings. The soil-brown stain under the fluorescence was almost certainly a bloodstain.
But whether it is human blood still requires further inspection.
"Compare it with Chen Lili’s blood type!"
Bloodstains that had dried for a long ti were difficult to extract DNA information from. For example, bloodstains on a freezer floor that had been cleaned were impossible to purify for examination, let alone extract DNA.
However, determining the blood type shouldn’t be much of a problem.
Wang Bei stood to the side, sowhat unclear on what the two had discovered.
However, Wang Bei was not stupid; he dared not speak or ask what they had found at that mont.
Old Bai excitedly rubbed his hands, "Aside from the Wu you ntioned, who else has driven this car?"
"Has Zhao Wenjun ever driven it?"
"This... probably not... no, I don’t know, but I haven’t seen President Zhao driving this car."
"Moreover, there are two car keys; one is always at the company, locked away with ."
"The other is with Wu Rui."
"After Wu Rui resigned, who did he give the car key to?"
"He didn’t co to the company when he resigned; the boss said he resigned, and he gave the key."
"Then I washed the car once as instructed, and it has remained parked since."
"If it weren’t for being busy lately, the car would have been sold."
"Why sell it?"
"President Zhao said no one was driving it and instructed to find ti to sell it."
Old Bai and Lu Chuan exchanged a glance, a rather improbable thought simultaneously crossing their minds.
"I’ll go check the blood type, Brother Bai; you report it to the higher-ups."
"Alright, we’ll split up!"
In the laboratory, Lu Chuan was conducting blood type matching.
Testing the blood type of long-dried bloodstains is troubleso, but it mainly requires ti and effort.
A qualified cri scene investigator or forensic doctor can achieve it.
"Type B blood!"
Lu Chuan looked at the color in the reagent bottle, frowning deeply.
Indeed, the blood type from the bloodstain in the trunk of the Accord did not match Chen Lili’s blood type.
Chen Lili’s blood type is Type A.
Having obtained the results, Lu Chuan dialed Old Bai’s number.
At this mont, Old Bai and Liu Guodong were in Qin Yong’s office.
"We found residual bloodstain traces inside Zhao Wenjun’s company’s Accord vehicle, and Lu Chuan is currently..."
Just then, Old Bai’s phone buzzed.
