Police Detective

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

　　 Today is Friday, there are not many cars backed up, but Liu Shuyuan is a little embarrassed to close a lane for this thing. I don't know how Sun Ge called the toll booth here, but he really paid too much attention to it.

　　 Bai Song curled his lips, expressing his obvious contempt (mu) for this bureaucratic style. After the car stopped, the two got out of the car under the sight of several toll gate staff.

　　 is a piece of automobile mudguard parts, which are basically hard plastics. This time, the piece of iron nailed between the top of the van-type truck mudguard and the box body is not big.

　　 "What do you plan to do?" Bai Song planned to seek Liu Shuyuan's opinion first.

　　 "This...you decide." Liu Shuyuan didn't have any good ideas either.

　　 "Take it back and go for a laboratory test to see if there are any messy things left behind." Bai Song said, "Do you have a bag with better airtightness in your car?"

　　 "No, there is a plastic box in the trunk. Just put it inside. The airtightness is still very good. I just take out the clothes and the box is no longer needed." Liu Shuyuan said.

　　 "That's fine, don't touch this piece of iron with your hands."

　　...

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

　　A lane is sealed, so sorry...

　　 The Criminal Division is far from here, and it takes nearly an hour to drive. On the way, Bai Song met Liu Shuyuan's contacts again, and actually contacted friends from the Criminal Division, and after a while, he directly carried out a simple test on this thing.

　　The matter of laboratory tests is actually very complicated. After all, various substances can not automatically show their appearance, but through different reagents to determine whether several of them exist or not.

　　 If you want to check whether there are traces of blood, contraband, etc. on the iron sheet, it is not difficult. But if you say, "I don't know what's in it, you can help me see what's in it", basically it will be difficult for a laboratory technician to handle it. .

　　 Criminal Research Institute, the full name of the Criminal Science Research Institute, Bai Song and this side have also had a lot of dealings, the police working here, if you only talk about law enforcement, case investigation, etc., they are definitely not as good as some professional criminal police. But here is more professional, the last time I refined gold, I used the laboratory here.

　　 drove here, as clean as ever. As a rare place for public security departments to engage in scientific research, this place has not always been a noisy place, but today, it seems a bit quieter.

　　 "What's the matter, there is no one in the courtyard?" Liu Shuyuan asked the security guard at the gate.

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

　　 The two entered the lobby of the main building, and only knew what was going on after chatting with the young lady at the front desk.

　　 Inside, the thief entered last night!

　　 Speaking of it, the high-walled compound in this place is not an easy place to recruit thieves, but it is a place where thieves are recruited. Where to go for reason...

　　 Of course, the thief didn't enter any building, he just wandered around in the parking lot and stole four electric car batteries. This can be regarded as a serious technical effort. The batteries lost are all lead-acid batteries. Without a lithium battery, each battery weighs thirty or forty kilograms.

　　 The thief came in over the high wall and could steal four batteries!

　　 This is really a bit level. Since there is no surveillance video at this angle, a large group of experts surrounded this area and started surveys.

　　As a ready-made subject, no one wants to let it go. After all, this case is solved. It is estimated that until retirement, in this compound, it is a capital worth bragging about!

　　 When Bai Song heard about this, he couldn't help but feel silent for the thief, fancy death, master!

　　 Liu Shuyuan made an appointment in advance, but didn't wait too much, and took the box directly.

　　 "What's the need?" The speaker was a 30-year-old policewoman, whose surname was Zhang, who should be familiar with Liu Shuyuan.

　　 "Check if there are any common contraband or du products." Liu Shuyuan gave a general idea.

　　 "Does this still need to be tested?" Sister Zhang said: "Isn't it more accurate to find a drug detection dog?"

　　 "Uh, that's right." Liu Shuyuan said: "Well, sister Zhang, you can help me check if there are any messy chemicals on it, uh, I know it's hard to test, you do your best."

　　 "All right." Sister Zhang nodded: "I also tested the one you mentioned by the way, and the result will be available in three hours."

　　 Sister Zhang took the box and left. Bai Song looked at Liu Shuyuan with a bit of bitterness at the door.

Three hours? He usually comes to send for inspection materials. Except for some major and important cases, which can be carried out quickly, others can sometimes be delayed for several days or even longer. As a result, in Liu Shuyuan's place, this is all right?

　　 "What is your relationship..." Bai Song once again expressed contempt for Liu Shuyuan.

"Haha, don't look at me. After all, our case may not be a general big case, right?" Liu Shuyuan saw what Bai Song wanted to say, "Honestly wait here for three hours, and look for something later. Something to eat."

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

　　 "Is it not good 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 by the way, bring some food to some people in the department." Liu Shuyuan said.

　　 After speaking, the two drove out and turned around. But the problem is that this neighborhood is too biased! The few places closest to here are all rural areas. Bai Song opened the map and looked at ~www.wuxiaspot.com~ There are only a few schools nearby.

　　 Liu Shuyuan drove to one of them. It is estimated that it is a vocational school. The school is not large and the management is not strict. After a long time, except for a larger supermarket, there is only a cafeteria.

　　 The canteen still had to use a meal card. The two wanted to ask the students to pay for it, but they were not as embarrassed, so they bought a lot of fruits and food from the supermarket and carried them into the car.

　　 It was past 12 o'clock when I returned to the Criminal Division, Bai Song still felt hungry after eating a few ham sausages, and said to Liu Shuyuan, "Do you have a canteen meal card here?"

　　 "No, but I know a few people, and it's okay to have a meal." Liu Shuyuan also felt that snacking was a bit light, especially when he broke with bananas on the road just now, and was even hungry.

　　 "Then dare to love, I don't know anyone here." Bai Song pointed to a few packages: "Send the fruits upstairs first."

　　 The two brought up the fruits they bought for others, and there was no one in the office. They went straight to the cafeteria after they had delivered them.
