A cordon was set up at the scene and one lane was closed.
Today is Friday, there aren't many cars, but Liu Shuyuan felt a little embarrassed to close a lane for this thing. I don't know why Brother Sun called the toll station here and said that, but he really took it too seriously.
Bai Song curled his lips, showing obvious contempt for this bureaucratic style. After parking the car, the two got out of the car under the watchful eyes of several toll booth staff.
It is a part of a car fender, basically made of hard plastic. What fell off this time was a piece of iron sheet nailed on the top of the van's fender and the box body, which is not very big.
"How do you plan to deal with this?" Bai Song planned to ask Liu Shuyuan's opinion first.
"This...you decide." Liu Shuyuan didn't have any good ideas.
"Take it back and have it tested to see if there are any messy things left." Bai Song said, "Do you have a bag in your car that is well sealed?"
"No, there is a plastic box in the trunk. Just put it in there. It is well sealed. I'll just take out the clothes and we don't need the box anymore." Liu Shuyuan said.
"Well, don't touch this piece of iron with your hands."
…
Soon, the two of them picked up the piece of iron sheet with the lid of the box and left in a hurry.
One lane is closed, so embarrassing...
The Criminal Science Institute is quite far from here, and it takes nearly an hour to drive there. On the way, Bai Song once again saw Liu Shuyuan's connections, and he actually contacted a friend from the Criminal Science Institute, and will directly conduct a simple test on this thing in a while.
Chemical testing is actually very complicated. After all, various substances cannot automatically show their appearance. Instead, different reagents are used to determine whether some of them exist or not.
If you want to check whether there is a trace of blood or contraband on the iron sheet, it is not difficult. But if you say, "I don't know what's in it, can you help me see what substances are in it", it will be difficult for the laboratory technician to do it...
The Criminal Science Institute, full name is the Criminal Science Institute. Bai Song has dealt with this place many times. The police working here are definitely not as good as some professional criminal police in terms of law enforcement, case investigation, etc. But this place is more professional. The last time we refined gold, we used the laboratory here.
When I drove here, it was as quiet as ever. As one of the few places in the public security department that conducts scientific research, it has never been a noisy place, but today, it seems a little unusually quiet.
"What's going on? There's no one in the yard?" Liu Shuyuan asked the security guard at the gate.
"I don't know. A lot of people went out early in the morning and I don't know where they went." The security guard didn't know much about this.
The two of them entered the main building lobby and talked to the lady at the front desk before they found out what was going on.
A thief broke into here last night!
To be honest, this place with high walls and large courtyards is not a place where thieves are likely to be attracted. But thieves did attract them, so how can we seek justice?
Of course, the thief did not enter any building, but just wandered around the parking lot and stole four electric vehicle batteries. This is a serious technical job, the stolen batteries were all lead-acid batteries, not a single lithium battery, and each weighed thirty or forty kilograms.
The thief climbed over the high wall and actually stole four batteries!
This is really quite a feat. Since there is no surveillance video from this angle, a large group of experts gathered around to investigate.
As this is a ready-made topic, no one wants to miss it. After all, if the case is solved, it will be something to brag about in this compound until retirement!
When Bai Song heard about this, he couldn't help but mourn for the thief. What a master!
Liu Shuyuan had made an appointment in advance, so he didn't wait long and took the box directly.
"What do you need?" The speaker was a female police officer in her thirties. Her surname was Zhang, and she should be very familiar with Liu Shuyuan.
"Test whether there are any common contraband or drugs on it." Liu Shuyuan gave a rough idea.
"Do we need to test this?" Sister Zhang said, "Wouldn't it be more accurate to find a drug-sniffing dog to smell it?"
"Uh, that's right." Liu Shuyuan said, "How about this, Sister Zhang, can you help me test whether there are any messy chemicals on it? Uh, I know it's difficult to test this way, please do your best."
"Okay." Sister Zhang nodded: "I'll also do the test for you. The result will be out in three hours."
Sister Zhang took the box and left. Bai Song looked at Liu Shuyuan with some resentment at the door.
Three hours? Usually when he came to deliver the materials for the inspection, except for some major cases, the inspection could be completed very quickly, while other cases could take several days or even longer. But for Liu Shuyuan, this was possible?
"What is your relationship..." Bai Song expressed his contempt for Liu Shuyuan again.
"Haha, don't look at me. After all, our case may not be an ordinary major case, right?" Liu Shuyuan saw what Bai Song wanted to say, "Just wait here for three hours and go find something to eat later."
After Liu Shuyuan said this, Bai Song really felt a little hungry. After running back and forth several times, it was already time for lunch.
"Isn't it not so nice to let people do experiments in the middle of the day?" Bai Song asked.
"I've been thinking about this too. Let's go and drive out to buy some fruit and bring some food to the people in the department." Liu Shuyuan said.
After that, the two drove out for a walk. But the problem was that this area was too remote! The nearest places were all rural areas. Bai Song opened the map and saw that there were only a few schools nearby.
Liu Shuyuan drove to one of them, which was probably a vocational school. The school was not big and the management was not strict. After walking around for a while, he found that there was only a cafeteria besides a larger supermarket.
You have to use a meal card in the cafeteria, and the two originally wanted to ask students to pay for them, but they didn't feel like doing it, so they bought a lot of fruits and food from the supermarket and carried them to the car.
It was already past midnight when Bai Song returned to the Criminal Investigation Department. After eating a few sausages, he still felt hungry. He asked Liu Shuyuan, "Do you have a meal card for the cafeteria here?"
"No, but I know several people, so it's not a problem for me to go and get a meal with them." Liu Shuyuan also felt that snacks were a bit bland, especially since he had just broken off a banana and eaten it on the way, which made him even hungrier.
"That's great. I don't know anyone here." Bai Song pointed at a few bags and said, "Let's send the fruits upstairs first."
The two of them brought up the fruits they bought for the other person. There was no one in the office, so after delivering the fruits, they went straight to the cafeteria.
