"Yeah." Su Ping responded.

At this moment, there was a knock on the door, and at the same time Old Wei's voice came from outside: "Captain Su, Captain Su, are you in there?"

"Here we come!" Su Ping replied and went to open the door.

Lao Wei took a graduate student into the small room and said at the same time: "The survey over there in the van is almost done, so I left one person to continue the detailed investigation and finish it, and we came over first. How about it, listen to Su Team, you said on the phone that there are important clues?"

Su Ping took out the sealed bag, handed it to Old Wei, and said: "The broken bones were found in the bathroom, and Xiao Qi sprayed them with luminol reagent once. There was a large area of ​​fluorescence reaction. We suspect that Chu Xunliang The body was probably dismembered in the bathroom and then further processed."

"This..." Old Wei hesitated for a while and said: "Although trace inspection is our task, this kind of biological traces, especially the further identification of objects that can cause the luminol reagent to produce fluorescent reactions, confirm whether they are blood and Is it human blood, or is it more from the forensic department..."

"I called you Lao Tu, I guess I'm here soon." Su Ping said, "I called you here because I want you to conduct a detailed investigation of the room to see if you can make any further discoveries, such as footprints and so on. If you can find enough The criminal evidence proving that other suspects were also involved in this case could not be better."

After a pause, Su Ping added: "Xiang Haichuan seems to pay great attention to personal hygiene, but I see that this floor has not been mopped for two days. You can use the vacuum coating sampling method to see if you can extract the footprints. If so. Bloody footprints are better."

"Okay, I'll give it a try." Old Wei finally nodded slightly and agreed.

Su Ping added: "The murder weapon...or the machete suspected to be the murder weapon was found hidden on Xiang Haichuan's bed, covered with a quilt."

"Hmm." Old Wei nodded, and finally his eyes fell on the safe and the gold bars placed on the safe: "This is... a gold bar? Let me go, is Xiang Haichuan so rich? Is this series of cases possible? Does it involve paying someone to kill someone?"

"No, please be careful..." Su Ping paused, thoughtfully, before he finished speaking.

It stands to reason that even if Xiang Haichuan was deceived, the price the deceiver sold him for such a large gold bar would probably not be cheap, so he would not be able to get it.

So what Old Wei Gang said is not unreasonable. This case may also involve paying a murderer to kill someone, and it may even use this fake gold bar as a means of payment.

Xiang Haichuan has spent most of his life in prison and has continued to commit crimes almost as soon as he was released from prison. He is likely to have a certain degree of anti-social personality and may also have a hatred of the police.

In this case, it is not impossible for someone to use thirty one-kilogram "gold bars" as a bargaining chip to ask him to kidnap and kill Chu Xunliang and Cao Mingyang.

Just when I thought of this, I saw Xiang Haichuan curl his lips: "I was shocked. I thought it was really a gold bar. The relationship was fake. It almost blinded me."

Qi Yuan couldn't help laughing.

Except for scammers, few people would make copper into this shape. The first thing that comes to mind is gold bars. However, due to the special physical properties of gold, it is actually quite easy to distinguish the authenticity of such a large gold bar.

Not to mention the color, many people may not be able to compare it without reference, but the density is different. Anyone with some common sense knows that the density of gold is extremely high. At the same time, the density of solids and liquids is also extremely difficult to change. It's hard to fake this.

Su Ping nodded lightly and said: "This gold bar is indeed fake. There are two possibilities. Xiang Haichuan may intend to deceive people, or he may be deceived. I prefer the latter.

Among the latter, it also includes the possibility you mentioned. This case may involve paying a murderer to kill someone. He received gold bars from Haichuan, but he was deceived and the gold bars were fake. So... you should investigate the gold bars carefully and see. Can you extract fingerprints or something?"

"No problem." Lao Wei accepted the task and said: "The surface of this 'gold bar' is very smooth, and it is easy to leave fingerprints. It is yellow and golden and strangely dazzling... Just wait for me to take a closer look."

Su Ping hummed.

A short while later, Tu Zhongxin also arrived at the scene. Su Ping briefly talked to him about the matter and asked him to go in to investigate.

A moment later, Su Ping received a call from Xun Mu, saying that a man was stopped by airport security because he was carrying too much gold. Although the gold was eventually found to be fake, he was detained by the airport police because of his panicked look. Down.

Because the airport public security also received the request from the criminal investigation detachment and fully cooperated to prevent the suspect from leaving Yuqiao through the airport.

Afterwards, the airport police noticed that he looked a little strange, so they gave him a urine test, and the result was positive.

"Fake gold... sucks..." Su Ping thought for a while and said: "Please ask the airport police to send you photos of fake gold. I will also send you a set of photos. You can identify it. If the gold style is Almost immediately, we will send someone to the airport to escort that guy back."

"Understood." Xun Mu responded and hung up the phone.

A few minutes later, his cell phone rang again, and Xun Mu told him that fake gold bars of the same size were found in the luggage of the suspect who was stopped at the airport, but the number was much smaller, only ten.

"Team Su!" At this time, the graduate student also ran out of the bedroom, holding a stack of award certificates in his hand, and said, "I found this thing inside the suspect's pillow. Take a look."

"What's this?"

"Certificate of participation and award certificate in the helicopter model sports competition." The graduate student said: "It looks pretty impressive. It just so happens that in this case, the suspect used a helicopter to send a USB flash drive containing the murder video to the Wanghua Community Police Station. Office? Here!"

Su Ping immediately took the pile of certificates, turned them over, and then raised his eyebrows slightly: "So, it was Xiang Haichuan who controlled the helicopter to deliver this U disk to us? Isn't this guy so ignorant? , I still have some skills on my hands, why don’t I just do my job..."

"Well, I may know a little bit..." Qi Yuan whispered: "Compared with toy helicopters, there is still a huge gap between model aircraft. They are expensive to build, especially oil-powered model aircraft such as oil-powered helicopters, which are even more expensive. Yeah, if your family is not well off, you can't afford to play, and if you're not particularly smart, you can't even think of making money from it."
