Mystery Tracker 3

The on-site inspection of the Bird Theater found nothing except for the surveillance video.So everyone's hopes are all focused on monitoring.

"Brother Jin, how many videos does Xiao Hao have to copy?" Qin Kai asked Cheng Jinsong on the car back to the police station, "When I left the police station, I saw him carrying a backpack of hard drives!"

"You want to know?" Cheng Jinsong smiled, "Okay, let me do the math for you. Generally, a 720p high-definition surveillance camera records about 16g a day. I just asked. There are 16 monitors in the Flying Bird Theater , we want to copy away its one-month video, what is the total capacity?"

"Hey brother Jin, please forgive me!" Qin Kai hurriedly begged for mercy, "I was the worst at mathematics when I was studying."

"Are there any of you who are not bad at studying?" Cheng Haiyang, who was on the side, complained about him.

"Okay, let me tell you," Cheng Jinsong said with a smile, "It's about 7600G. Xiaohao's hard drives have 1T of memory. You need to use up to 8 hard drives like this."

"My God! So many?!" Qin Kai was surprised, "Don't even read it, it will take a long time to copy it!"

"Hey, you're right." Cheng Jinsong continued to popularize science, "The current USB transmission ports are generally 3.0, and the transmission speed can reach 300mb~500mb per second, which means that the content of 1G takes about 2-3 seconds. It can be uploaded, but just like this, it will take 6 and a half hours to copy all those videos-this is still an ideal situation. If you count the speed drop caused by the overheating of the machine, these are actually uploaded, and it will take more than 7 hours .” Speaking of which, Cheng Jinsong looked at his watch, “Well, Xiao Hao will be able to finish work before 22:[-] today, so it will be fast.”

"It's no wonder that Xiao Hao is wearing glasses now. It's strange that such a view is not myopic." Qin Kai sighed.Speaking of which, he suddenly laughed when he thought of something, "Well, I think it's good if Xiao Hao doesn't return to the game today, and it will save him embarrassment."

"Embarrassed?" Shen Yan said this time, "Why is he embarrassed?"

"Ha, boss, you don't know yet, do you? Xiao Hao was 'hanged' by a female police officer in the bureau today!" Qin Kai immediately described Shen Yan and Cheng Jinsong he had seen in the forensic office before. I said it again.As a veteran police officer who has been gossiping for 30 years, Qin Kai highlighted the details of the story very well, especially when Tang Qing unceremoniously sat in Shen Hao's seat and began to check the surveillance, Qin Kai kept winking, She imitated Shen Hao's expression of surprise and astonishment vividly.

"I said Qin Kai, it's a waste if you don't go to the Internet to do some talk shows." Cheng Jinsong laughed at him, and said to Shen Yan, "Captain Shen, I think Qin Kai should let Qin Kai get any publicity from the police and the public in the future." Go shoot, with this eloquence, the number of clicks is absolutely overwhelming."

"Well, I think so too." Shen Yan also agreed with a smile, "Qin Kai, you really have the courage to arrange my brother like this in front of my own brother."

"Hey, looking for fun at work." Qin Kai is not afraid of Shen Yan's "threat", "And I didn't lie, all my statements are in line with the facts, even if I am asked to testify in court, I dare Let’s put it this way.” Seeing Shen Yan laughed again, Qin Kai continued, “But I think that little girl Tang Qing does have some tricks. Brother Jin, I think you can think about it.”

"Me?!" Cheng Jinsong didn't expect that Qin Kai would suddenly cue him, but in front of Shen Yan, he was so frightened that he almost turned the wrong steering wheel. He subconsciously glanced at Shen Yan, and Cheng Haiyang was already there. Speak for him: "No, what does this have to do with Brother Jin?"

"Consider recruiting her into the forensic team!" Qin Kai replied as a matter of course, he glanced at Cheng Jinsong through the rearview mirror, "Brother Jin, isn't your team still short of manpower? And Xiaorou is pregnant again, it won't be long You will have to take maternity leave, and then your manpower will be even more insufficient. I think that little girl has a brain and can do things quickly." Speaking of this, he smiled gossip again, "And I think she should be a good partner with Shen Hao Yes, you said that if the two of them really have some development in the future, Brother Jin, you are considered old, right?"

Cheng Jin said in his heart that I thank you for taking a big breath, which almost scared me out of a heart attack.But Shen Yan over there has already said seriously: "Qin Kai, it's fine for you to talk about these gossips with us, but don't talk nonsense with other people when you return to the game. Tang Qing is here to help us work. It's not good for Tang Qing or our crime team to gossip."

"That's right, people should think that our colleagues in the criminal investigation team like to spread rumors about the relationship between men and women." Cheng Haiyang also scolded him.Qin Kai just wanted to explain a few words for himself, but Cheng Jinsong spoke before him: "It's Qin Kai, you can't treat others like love at first sight just because you are 'love at first sight' to your girlfriend."

Qin Kai's girlfriend got married two months ago, and the process was quite dramatic.It is said that when Qin Kai was taking the subway outside, he happened to run into a girl who accused the man behind her of harassing her. Unexpectedly, the man became so angry after being exposed that he pushed him away and ran away.Qin Kai happened to be beside him at the time, so he immediately ran over and held the man down in three or two steps.Then the subway police on duty also came over and subdued the man.I didn't want the man to be dishonest when he was caught, but he even bit back and said that Qin Kai and the girl partnered to defraud him.At this moment, Qin Kai took out his police officer ID and patted it in front of the wretched man, and the wretched man was dumbfounded.The young girl was very moved by Qin Kai's heroic behavior, and rushed up to give Qin Kai a hug.Of course, the girl let go after hugging her, but for an older youth who has been single for 30 years, this hug is enough to generate the motivation to chase someone.So Qin Kai immediately added the other party's WeChat under the name "you can contact me if you need to in the future", and then successfully got rid of the predicament of being single.

Hearing Cheng Jinsong mention his girlfriend, Qin Kai smiled instantly.He was about to say something when his phone rang. As soon as Qin Kai picked it up, his voice immediately became sweeter by an octave: "Hey, baby, I was investigating the case just now..."

"Ugh." Cheng Haiyang beside him made an exaggerated retching motion.Cheng Jinsong and Shen Yan looked at each other with a smile——

Your brother was really hanged and beaten by his junior sister?

That's your apprentice too, okay?

——"Ah, sneeze!" Shen Hao in the theater sneezed loudly.

If there were a few people in the car joking and laughing while they were busy, then when they returned to the police station to gather information from all parties, they couldn't laugh anymore.First of all, the call records of Hu Qianqian's mobile phone obtained from the telecommunications company showed that Hu Qianqian did not make any calls on the evening of the 3rd; Has not had any contact with Hu Qianqian.The surveillance videos in the city and Zhao Yunxiang's community all confirmed that Zhao Yunxiang returned to his home directly after sending his girlfriend home, and his behavior was not suspicious; in addition, Fang Liyuan also brought back a piece of bad news. During the search, the police searched almost all suspicious locations with a radius of 3 kilometers around Chengnan University City, but they did not find any other parts of Hu Qianqian's body.

"Both Team Zhao and I feel that the possibility of the murderer throwing the remaining corpses near the university town is very low." Fang Liyuan said, "The police have been searching and controlling this area for two consecutive days. As long as the murderer pays attention, he will notice , he probably wouldn’t take such a big risk to dump the body here again. Of course, for safety’s sake, Team Zhao and the others will still deploy control in key areas tonight.”

Shen Yan nodded: "If I haven't found it tonight, I will apply to Director Xiao tomorrow to expand the scope of the search."

"Do you think the murderer will throw his body six or seven times like the murderer 20 years ago?" Cheng Haiyang looked at the others.

"No." "I don't think so."

Cheng Jinsong and Shen Yan spoke at the same time.Cheng Jinsong smiled: "Captain Shen, please speak first."

"The more times the murderer dumps the body, the greater the possibility of being discovered." Shen Yan said, "Now that there are surveillance everywhere in the city, it is unrealistic for the murderer to escape the cameras every time."

"I think so too." Cheng Jinsong nodded in agreement, "The murderer dismembered the body just to make us connect this case with the case 20 years ago. But in the case back then, the murderer divided the dead man's muscles into two parts. Abandoned, the internal organs were also divided twice, which means that the last time the murderer threw the same amount as four times 20 years ago. Now that there are so many surveillance cameras in the city, every time the murderer throws more, he takes the risk of being discovered again. I don't think he doesn't understand that."

"Speaking of which, this murderer is really cunning," Cheng Haiyang said. "You say, the surveillance in our city covers at least 100%, if not 90%, right? But this guy kidnaps and throws his body once. , It’s really annoying that none of them were caught by surveillance cameras.”

"I said Haizi, which means that this grandson definitely planned it long ago." Cui Mingyou said, still with a strong Tianjin accent, "In the area where he threw his body for the first time, there are two snack streets and four. It is not uncommon for a school gate to walk around with large black garbage bags. Several colleagues in the video team have picked out more than a dozen people carrying black plastic bags, but so far none of them are suspected of committing crimes; That day happened to be the last day of the long holiday. There were many parents of college students driving their children back to school, so there were a lot of vehicles entering and leaving within 24 hours. Several colleagues in the video team copied the license plate numbers and got hand cramps—the key is, why? There are many cars, how do you check? You can’t go door-to-door to check people’s trunks, right?”

"Brother Cui is right." Cheng Jinsong went on to say, "In fact, I think that compared with dumping the body, the murderer's kidnapping of Hu Qianqian showed more obvious planning. The murderer deliberately parked the car in the blind spot of the theater. , and deliberately got people into the car before the end of the performance, that is, before a large number of audiences came out, which minimized the possibility of being discovered. Moreover, judging from Hu Qianqian's actions at the time, she Evidently known to the killer - at least to some degree."

"So the murderer should be someone she knows." Cheng Haiyang followed this line of thought to analyze, "Jiang Li just said that Hu Qianqian didn't make a call before she disappeared, which means she made a voice call - maybe it's WeChat or @**? "

"Almost," Cheng Jinsong nodded, "but the problem is that Hu Qianqian's mobile phone and computer are not there, and it takes a lot of time to check her online call records."

"This case is true. We have investigated both ends, but we just can't find a specific suspect." Qin Kai scratched his head, "It's a good thing that the common people don't know what happened. If they know, they might not know what to say. Where are we the police?"

However, I don't know if Qin Kai's mouth was open. Before he finished expressing his emotions, Cheng Jinsong's cell phone rang.Cheng Jinsong glanced at the news, then glanced at Qin Kai, and said to everyone: "Ruiheng told me that there are rumors about this case on the Internet."
