Police Detective

A cordon was pulled at the scene and one lane was closed.

Today is Friday, there are not many cars, but Liu Shuyuan is a little embarrassed to close a lane for this thing. I don’t know why Brother Sun called the toll station here. He really took it too seriously.

Bai Song curled his lips and expressed clear contempt (xian) (mu) for this bureaucratic style. After the car parked, the two got out of the car under the eyes of several toll station staff.

It's just a piece of car fender, basically made of hard plastic. What fell off this time was a piece of iron nailed to it between the van's fender and the box. It wasn't that big at all.

"How are you going to deal with it?" Bai Song planned to seek Liu Shuyuan's opinion first.

"It's up to you to 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 better-sealed bag in your car?

"No, there is a plastic box in the trunk. Just put it in there. The sealing is still very good. I will just take out the clothes. I don't need the box." Liu Shuyuan said.

"Okay, don't touch this piece of iron with your hands."

Soon, the two of them packed up the piece of iron sheet with the lid of the box and left in a hurry.

It's embarrassing to have a lane blocked.

The Criminal Division is quite far from here, it takes nearly an hour to drive. On the way, Bai Song once again saw Liu Shuyuan's connections. He actually contacted a friend from the Criminal Division, and soon conducted a simple test on this thing.

The matter of testing is actually very complicated. After all, various substances do not automatically show their appearance. Instead, different reagents are used to determine whether some of them exist.

It is not difficult to check whether there is trace amounts of blood, contraband, etc. on the iron sheet. But if you say, "I don't know what's in this, please help me find out what substances are in this", it will basically be difficult for the laboratory technician. .

The Institute of Criminal Science, the full name of which is the Institute of Criminal Science, is a place Bai Song has dealt with many times. The police working here are definitely not as good as some professional criminal police in terms of law enforcement, case handling and investigation. But this place is more professional. The last time gold was refined, the laboratory here was used.

I drove here and it was as clean as ever. As one of the few places where the public security department conducts scientific research, this place has never been a noisy place, but today, it seems a little extra quiet.

"What's going on? There's no one in the courtyard?" Liu Shuyuan asked the security guard at the gate.

"I don't know. There are a lot of people out there early in the morning, and I don't know why they are there." The security guard didn't understand this.

The two entered the lobby of the main building and chatted with the lady at the front desk before they found out what was going on.

Here, a thief broke in last night!

Speaking of which, this place with its high-walled compound is not an easy place to attract thieves, but it does attract thieves. How can I explain it?

Of course, the thief did not enter any building, but just wandered around the parking lot and stole four electric vehicle batteries. This was a serious technical job. The lost batteries were all lead-acid batteries, not a single lithium battery. Each one weighed thirty or forty pounds.

The thief climbed over the high wall and was able to steal four batteries!

This is really a bit low-level. Since there is no surveillance video from this angle, a large number of experts gathered around the area to conduct surveys.

As a ready-made subject, no one wants to let it go. After all, if this case is solved, it will probably be something worth bragging about in this compound until retirement!

When Bai Song heard about this, he couldn't help but feel silently for the thief. He is a master in trying to commit suicide!

Liu Shuyuan made an appointment in advance and took the box directly without waiting.

"What do you need?" The speaker was a policewoman in her thirties, surnamed Zhang, who should be familiar with Liu Shuyuan.

"Test whether there are any common contraband or drugs on it." Liu Shuyuan gave a rough idea.

"Does this still need testing?" Sister Zhang said, "Wouldn't it be more accurate to find a drug-detecting dog to sniff it?"

"Uh, that's right." Liu Shuyuan said, "Okay, Sister Zhang, please help me test whether there are any messy chemicals on it. Um, I know it's difficult to test. Please do your best."

"Okay." Sister Zhang nodded: "I'll take the test for you by the way. The results will be available in three hours."

Sister Zhang took the box and left. Bai Song looked at Liu Shuyuan with some resentment at the door.

Three hours? He usually comes here to deliver inspection materials, and except for some major cases, which can be done very quickly, other cases sometimes take several days or even longer. But in Liu Shuyuan's case, this is all right?

"What kind of relationship do you have?" Bai Song once again expressed his contempt for Liu Shuyuan.

"Haha, don't look at me. After all, our case might not be an ordinary major case, right?" Liu Shuyuan could tell what Bai Song wanted to say, "Just wait here for three hours, and we'll find some later. Something to eat.”

When Liu Shuyuan said this, Bai Song was really a little hungry. After running back and forth a few times, it was already time for lunch.

"Isn't it bad to let people do experiments at noon?" Bai Song asked.

"I'm also thinking about this issue. Let's go. Let's drive out to buy some fruit and bring some food to a few people in the department." Liu Shuyuan said.

After saying that, the two drove out for a walk. But the problem is, this neighborhood is too remote! The nearest places here are rural areas. Bai Song opened the map and looked at it. There were only a few schools nearby.

Liu Shuyuan drove to one of them. It was probably a vocational college. The school was not big and the management was not strict. After walking around for a long time, except for a larger supermarket, there was only a canteen.

You also need to use a meal card in the canteen. They originally wanted to ask a student to pay for it, but they were still embarrassed, so they bought a lot of fruits and food from the supermarket and carried them to the car.

It was past twelve o'clock when we returned to the Criminal Division. Bai Song still felt hungry after eating a few ham sausages, so he asked Liu Shuyuan: "Do you have a meal card for the canteen here?"

"No, but I know a few people, so it's okay to have a meal." Liu Shuyuan also felt that snacks were a bit bland, especially since he broke off a banana to eat on the way just now, which made him even hungrier.

"That's good, I don't know anyone here." Bai Song pointed to a few bags: "Send the fruits upstairs first."

The two of them brought up the fruits they bought for others, and there was no one in the office. After delivering them, they went directly to the canteen.
