Chapter 245 This is not the blood of the deceased
Old Bai pushed up the reading glasses on the bridge of his nose.
There are nine vehicles in total, six of which are cold chain transport vehicles. They are large and inconvenient to move. If Zhao Wenjun really transports corpses silently, these vehicles are obviously not suitable.
The rest are two cars and one off-road vehicle.
"Off-road vehicle, Mr. Zhao usually drives this one, and he rarely drives other cars."
"Okay, take us to have a look."
The off-road vehicle Wang Bei mentioned is a hard-core off-road vehicle that has been modified.
The car was parked in the parking lot of Jiuding Fruit Wholesale Market.
"Xiao Lu, let's start with this car."
Lu Chuan nodded. This time, he came out to do the work. Lao Bai led the team. He said which car to clean. , just wipe which car.
The collection and analysis of trace evidence for a vehicle is very energy-consuming and time-consuming.
Lu Chuan has done similar work before, such as tires.
The dirt and gravel used by vehicle tires can reveal to a certain extent where the vehicle has been, what roads it has traveled on, and even when it has been there.
A little dust on the wheel eyebrows can tell when the vehicle has been cleaned and where it has been.
Of course, the focus of Lu Chuan's collection of trace evidence this time was not to analyze where the vehicle had been.
Even if Zhao Wenjun drove this car to transport corpses, it would be difficult to tell whether the car had been to the body dumping site based on the materials left on the vehicle for more than a month.
The focus of Lu Chuan's trace evidence testing this time was on the space inside the car to see if Chen Lili's biological traces could be found.
First of all, there are fingerprints. Turn on the ultraviolet light, and there are fingerprints all over the steering wheel, door handles, and seats.
With so many fingerprints, it is really time-consuming to wipe them out.
But there is no way. What stands out in the collection of trace evidence is meticulousness.
Not to mention fingerprints, even a few micrograms of soil cannot be let go.
“Except Zhao Wenjun, can anyone else drive this car?”
Wang Bei shook his head: “Of course not, this is Mr. Zhao’s special car, and it costs hundreds of thousands. We I usually drive two cars.”
Wang Bei pointed to a black Accord and a Jetta.
While Lu Chuan was collecting trace evidence, Lao Bai was chatting with Wang Bei.
Lao Bai really couldn't help with this kind of work, not to mention his lack of skills, even his eyesight.
In the past two years, Lao Bai has to wear reading glasses when reading, and his eyesight is getting worse every year.
“Let’s go over and have a look.”
“Okay, okay, I’ll get the keys.”
Although the two cars look okay from the outside, at first glance If you know the car models, you will know that they are all old cars.
"Bought second-hand?"
"They are all second-hand," Wang Bei nodded: "The Jetta was bought three years ago, and the Accord was bought last year."
"Really?"
Lao Bai approached the black Accord car and showed great interest in it: "It looks good, how much did it cost?"
"More than 130,000 yuan. It’s not expensive.”
"Hmm, it's really not expensive. I want to buy one too, but I just can't find the right one."
Lao Bai opened the back seat door: "This Accord has good space, and a used car also retains its value. . ”
“That’s right. I’ve driven this car twice since I bought it last year.”
“You’ve only driven it twice?”
“Then. Who usually drives it? ”
"Xiao Wu, we are the newcomers who came in September. I heard that they are college graduates and can't find a job."
"Oh, that's a pity..."
Lao Bairao Go to the trunk of the car and open the trunk door: "The trunk space is not small, it is suitable for home use."
As he said that, Lao Bai opened the trunk cover from left to right and took a casual look.
“By the way, is that Xiao Wu your driver?”
"That's not true. He didn't seem to do much work after he came here. He had a good relationship with Boss Zhao. Anyway, he kept driving this car. But then he resigned, just last month, it seems."
Resigned ?
"What was the date last month?" "The second, the second."
"Do you know why you resigned?"
"I don't know about this. He suddenly stopped coming. The boss said he resigned."
"What is this Xiao Wu's name?"
"Wu Rui, his name is Wu Rui."
Lao Bai thought about it for a while and returned to the off-road vehicle.
Lu Chuan stuck his butt out and was wiping the fingerprints on the passenger door.
"Xiao Lu, we will do this later. Come and take a look at this."
Opening the cover on the right side of the trunk, Lao Bai pointed to the corner: "Look at this, does it look like it?"
Although Lao Bai didn't say what it was like, Lu Chuan still didn't understand what it meant.
When I walked in and took a look with an ultraviolet lamp, the earthy brown scars were very conspicuous.
A flash of excitement flashed across Lao Bai's face, it really took no effort at all.
"That's it, right?!"
Lu Chuan nodded affirmatively at Lao Bai's muttering. Under the fluorescence, there were earthy brown traces, which were basically blood stains.
But whether it is human blood or not, we have to go back and check.
“Compare it with Chen Lili’s blood type!”
Although it is difficult to extract DNA information from blood stains that have dried for a long time, such as the blood stains on the floor of the cold storage, because they have been cleaned, checked and purified. Not enough, let alone detecting DNA information.
But there shouldn’t be much of a problem in detecting the bleeding type.
Wang Bei stood aside, somewhat confused as to what the two of them had discovered.
However, Wang Bei was not stupid. He did not dare to speak at this time, nor did he ask what he had found.
Lao Bai said excitedly: "Besides the Xiao Wu you mentioned, who else has driven this car?"
"Has Zhao Wenjun driven it before?"
"This... there shouldn't be... No, no, I don't know about this either. Anyway, I have never seen Mr. Zhao drive this car."
"Furthermore, this car has two keys, one always It’s locked here at the company.”
“The other one is in Wu Rui’s house.”
“Who gave the car key to Wu Rui after he resigned?”
“When he resigned, he did not come to the company. The boss told him to resign, and he gave me the key.”
"After that, I washed the car once, and then the car was left untouched."
"If it hadn't been busy recently, this car would have been sold."
"Why did you sell it?"< br>
"Mr. Zhao said that no one opened it, and told me to find time to sell it."
Lao Bai and Lu Chuan looked at each other, and an unlikely idea came to their minds at the same time.
"I'm going to check the blood type, Brother Bai, please report to the superiors."
"Okay, let's split up!"
In the laboratory, Lu Chuan is doing blood type matching.
Although blood type testing of long-dried blood stains is troublesome, it is nothing more than a waste of energy and time.
A qualified investigator or forensic doctor can do it.
"Blood type B!"
Lu Chuan looked at the contrasting colors in the reagent bottles and frowned deeply.
Sure enough, the blood type of the blood stains in the trunk of the Accord was not successfully compared with Chen Lili’s blood type.
Chen Lili’s blood type is type A.
After getting the result, Lu Chuan called Lao Bai.
At this moment, Lao Bai and Liu Guodong are in Qin Yong's office.
"We found residual traces of blood in Zhao Wenjun's Accord car. Lu Chuanna was looking at..."
Just as he said this, Lao Bai's cell phone buzzed.
