Lao Bai pushed the reading glasses on the bridge of his nose.

There are a total of nine vehicles, six of which are cold-chain transport vehicles, which are large and inconvenient to move, if Zhao Wenjun really transports the body silently, these cars are obviously not suitable.

All that's left are two sedans, as well as an off-road vehicle.

"Off-road vehicles, Mr. Zhao usually drives this, and other cars don't drive much."

"Okay, take us around."

The off-road vehicle Wang Bei mentioned is a hard-core off-road vehicle, which has also been modified.

The car was parked in the parking lot of the Jiuding Fruit Wholesale Market.

"Xiao Lu, let's start with this car."

Lu Chuan nodded, this time he came out, he was working, Lao Bai led the team, he said that he would wipe whichever car he was, he would wipe whichever car.

Collecting and analyzing trace evidence for a vehicle is very laborious and time-consuming.

Lu Chuan has done similar work before, such as tires.

The dirt and gravel from the tires of the vehicle to work can reveal to a certain extent where the car has been, what roads it has walked, and even when it has been.

A little dust on the wheel arch can determine the time when the vehicle has been cleaned and the place it has been.

Of course, Lu Chuan's collection of trace physical evidence this time is not focused on analyzing where the vehicle has been.

Even if Zhao Wenjun drove this car to transport the body, more than a month has passed, and it is difficult to judge whether the car has been to the scene of the body dumping based on the materials left on the vehicle.

Lu Chuan's inspection of trace physical evidence this time focused on the space inside the car and whether Chen Lili's biological traces could be found.

First of all, there are fingerprints, turning on the UV lamp, steering wheel, door handles, and seats are all fingerprinted.

With so many fingerprints, trying to erase them out is really time-consuming.

But there is no way, the collection of trace physical evidence is highlighted by a meticulous one.

Not to mention fingerprints, even a few micrograms of soil, you can't let go.

"Except for Zhao Wenjun, will anyone else drive this car?"

Wang Bei shook his head: "Of course not, this is Mr. Zhao's special car, hundreds of thousands of dollars, we usually drive two cars."

Wang Bei pointed to the side, a black Accord and a Jetta.

When Lu Chuan was collecting trace physical evidence, Lao Bai was chatting with Wang Bei.

This kind of work, Lao Bai really can't help, not to mention that the technology can't work, even the eyes can't.

In the past two years, Lao Bai has to wear reading glasses to read, and his eyes are not as good as a year.

"Let's go, let's take a look."

"Okay, okay, I'll go get the key."

Although the two sedans look okay from the outside, they know that they are all old cars when they look at the models.

"Second-hand?"

"It's all second-hand," Wang Bei nodded, "The Jetta bought it three years ago, and the Accord bought it last year."

"Really?"

Lao Bai approached the black Accord and showed great interest in it: "It looks good, how much did you buy it?"

"It's more than 130,000, but it's not expensive."

"Mmmm, it's really not expensive, I want to buy one, but I can't find the right one."

Lao Bai opened the door of the back seat: "This Accord has a good space, and the value of the second-hand car is also maintained."

"Yes, I've driven this car twice since I bought it last year."

"You've only driven twice?"

"Who's usually going to open it?"

"Xiao Wu, our newcomer who came in September, I heard that he is a college graduate, and he can't find a job."

"Oh, that's a pity......

Lao Bai went around to the trunk of the car and opened the trunk door: "This trunk space is not small, and it is quite suitable for home."

As he spoke, Lao Bai opened the trunk lid left and right and looked at it casually.

"By the way, that Xiao Wu is your driver?"

"It's not, he doesn't seem to have done much work since he came, and he has a good relationship with Boss Zhao, so he has been driving this car anyway, but then he resigned, just last month

It seems to be."

Resign?

"What day was last month?"

"Two, just two."

"Do you know why you quit?"

"I don't know this, I suddenly didn't come, and the boss said he resigned."

"What's this Xiao Wu's name?"

"Wu Rui, called Wu Rui."

Lao Bai pondered for a while and returned to the off-road vehicle.

Lu Chuan was pouting and wiping his fingerprints on the passenger door.

"Xiao Lu, I'll do this later, come and see this."

Flipping open 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 looked like, Lu Chuan still didn't understand what it meant.

When I walked in, I was illuminated by an ultraviolet lamp, and the earth-brown scar was very conspicuous.

A trace of excitement flashed on Lao Bai's face, it really didn't take any effort to come by.

"That's it, right?!"

Lu Chuan nodded affirmatively at Lao Bai's muttering, and the fluorescence showed earthy brown traces, which were basically bloodstains.

But whether it was human blood or not, we have to go back and check it.

"Compare it with Chen Lili's blood type!"

Although it is difficult to extract DNA information from blood stains that have dried up for a long time, such as blood stains on the cold storage floor, because they have been cleaned, they cannot be checked and purified, let alone detect DNA information.

However, there should be no big problem in detecting the bleeding type.

Wang Bei stood aside, a little puzzled by what the two had discovered.

However, Wang Bei was not stupid, he didn't dare to speak at this time, and he didn't ask what he found.

Lao Bai rubbed his hands a little excitedly and said, "Who else has driven this car except for Xiao Wu you said?"

"Has Zhao Wenjun ever driven it?"

"This ...... Probably not...... No, no, I don't know about this, anyway, I haven't seen Mr. Zhao drive this car."

"Moreover, this car has two keys, one of which is always in the company, locked with me."

"There's another one in Wu Ruina."

"After Wu Rui resigned, who did he give the car keys to?"

"When he resigned, he didn't come to the company, it was the boss who said he resigned, and he gave me the key."

"When it's over, I washed the car once, and then the car sat untouched."

"If it weren't for the recent busyness, this car would have been sold."

"Why sell?"

"Mr. Zhao said that no one opened it, so he told me to find time to sell it."

Lao Bai and Lu Chuan glanced at each other, and an unlikely idea popped up in their hearts at the same time.

"I'll check the blood type, Brother Bai, you can report to the higher-ups."

"Okay, split up!"

In the laboratory, Lu Chuan is doing blood group matching.

Although the blood group test that has dried up for a long time 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 bottle, and his brows furrowed deeply.

Sure enough, the bloodstained blood type in the trunk of the Accord car did not compare with Chen Lili's blood type successfully.

Chen Lili's blood type is type A.

After getting the result, Lu Chuan dialed Lao Bai's phone.

At this moment, Lao Bai and Liu Guodong were in Qin Yong's office.

"We found traces of blood stains in the Accord of Zhao Wenjun's company, and Lu Chuanna was ...... it."

As soon as he said this, Lao Bai's mobile phone buzzed.
