Mystery Tracker 3

Some people say that modern police investigation is a kind of "jigsaw puzzle". To some extent, this sentence has some truth.Several police officers in the video team sorted out all the vehicles parked in the monitoring blind spot through the surveillance video of the Flying Bird Theater. All vehicles that have entered and exited the area were cross-compared, and these 74 vehicles were found.

The police immediately found out the owner information of the four cars from the vehicle management office, and compared them with the university, and finally confirmed that one of the four cars belonged to a biology teacher at S University, and the other belonged to The car of the teacher of S City College of Science and Technology, and the other two are the cars of the parents of the students - one child is studying in the Physics Department of S University, and the other is studying clinical medicine at S City Medical University.

The police immediately questioned these people, but after the first round of interviews, everyone behaved normally.What made the police even more disappointed was that the police tested all four cars, and as a result, there was no blood reaction in any of the four cars.Of course, the police will not lift their suspicions because of this, and further investigations will begin immediately.

"Actually, the murderer may not have driven the same car in the two operations. It is not uncommon for a family to have two or three cars, not to mention that the murderer may have accomplices. One car is used to kidnap people, and another is used to dump the body. It doesn't take much effort to exhaust our police to death."

It was Cui Mingyou who spoke.Now they are standing in front of the whiteboard in the meeting room to analyze the case again.

"What Brother Cui said is very possible." Cheng Jinsong also nodded in agreement, "The murderer's plan is so thorough, the details of the car will definitely be taken into consideration, and it is not impossible to clean the interior of the car or even replace the interior afterwards. What's more, we have now It’s not even confirmed how many people committed the crime, there are too many possibilities.”

"One more thing," Jiang Xin also said, "Have you found the rest of the dead body?"

Fang Liyuan shook his head: "The sub-bureau and the police station have searched the whole city, but so far no remaining bodies have been found."

"Don't you think this is also strange?" Jiang Xin said, "Today is the 9th, and the murderer threw out the first part of the body on the 6th. Normally, he should dispose of the other parts soon, but why? We haven't found the rest of the body for three whole days? If the murderer has dumped the body, is there something we missed? If the murderer hasn't dumped the body, why hasn't he acted yet? We have sent out the case report and he left Looking at the dead body, once we the police find the door, wouldn’t the evidence be conclusive?”

"If he did not throw the body away, it is very likely that there is definite and strongly directional information on the remaining body parts. Once we find out, we can lock the suspect." Cheng Jinsong analyzed, "Moreover, the murderer probably I am more confident in my current safety and think that the police will not find him."

The room fell into a brief silence again.What Cheng Jinsong said made sense, but where is the breakthrough?If the murderer was as Cheng Jinsong said, how should the police find him?

While they were silent, suddenly footsteps came from the door.Shen Hao walked in quickly: "Brother! Good news, the software company has passed all the data of Hu Qianqian and Chi Jiawei to us!"

As soon as this remark came out, the spirits of several people in the room were lifted.All of Hu Qianqian's contacts and the time of communicating with them were listed on Shen Hao's laptop, but the content of the message was not displayed.

"No specific content of their chat?"

"Software companies will only capture the high-sensitivity words in all chats, but they will not record the specific content of the chats. This belongs to the privacy of citizens. But we can see when they talked with everyone, you see , "Speaking, Shen Hao pulled Hu Qianqian's data information to the end, "She did make a voice call with someone at 3 o'clock in the evening on the 9rd!"

"This is the person who lured her out!" Shen Yan was excited, "Check it out, who owns this number!"

"it is good!"

Shen Hao entered the number on the account, and immediately an ID with a male picture as the profile picture popped up.Several people recognized at a glance that the man was Hu Qianqian's idol Anthony.And the name of this person is also very straightforward, called "Aini 365".Shen Hao immediately contacted the software company, and soon found out the registration information and login IP of the account.Then, they found the registrant's ID number through the registered mobile phone number.When the identity information of this person appeared on the computer screen, everyone was shocked at the same time——

Cao Lu? !

Police station, interrogation room.

Putting on the detention clothes and sitting on the special chair for interrogation, Cao Lu's eyes were full of panic.

"Cao Lu, from the afternoon to the evening of the 3rd of this month, where are you and what are you doing?" Shen Yan asked.

"It was the day before the long holiday," Cao Lu said nervously, "I made an appointment with my classmates to go to Suzhou together, so I flew to Suzhou on the night of the 3rd."

"What time is your flight?"

"At 4:50pm, landed at 7:[-]pm."

"What did you do after landing?"

"After landing, I went to the hotel."

"What are you doing after 9 o'clock?"

"I just watch dramas in the hotel and surf the Internet. Police officers, you can go and check the hotel's surveillance!"

"Then let's talk about your mobile phone card and Q number." Cheng Jinsong said this time, "You said they are not yours, but we found out from the telecommunications company that the mobile phone number bound to the Q number is indeed yours. The card issued by the identity information."

"Officer, I told you, I really didn't open that one! Someone must have stolen my ID card and opened it!" Cao Lu eagerly argued.

"Then where do you usually keep your ID card? Who might have access to it?"

"I put it in my wallet, which I usually carry with me, but when I go back to the dormitory, I often leave the bag in the dormitory when I go to eat or take a shower, so if someone really wants to steal it, it's easy to steal it. Here we go!"

There is some truth to Cao Lu's statement.So Shen Yan went on to the next question: "You and Hu Qianqian had conflicts before, didn't they?"

"Yes, we were in the same dormitory when I was a freshman. I don't know where I provoked her. She just talked sarcasticly at me all day long. Later, she poured cold water on my quilt and put washing powder in the thermos bottle! Think about it, officer. , Is this something a college student did?! You said that if she put something else, I would have been poisoned to death without knowing it!! I wanted to call the police, but the school teacher said there was no evidence that she did it, He also said to change the dormitory for me, I don’t want to really make her crazy, otherwise she doesn’t know what else to do…” At this point, probably remembering the purpose of the police’s question, Cao Lu immediately added , "But officer, I won't kill someone just because of this kind of thing! Hu Qianqian's death has nothing to do with me!..."

After leaving the case handling area, Liu Xingyan, Cao Lu's counselor, was waiting outside the door.Seeing Shen Yan coming out, she hung up the phone she was on, walked over and asked, "Captain Shen, how are you doing?"

"We still need to conduct further investigations on Cao Lu. According to regulations, we will temporarily detain her."

"What?!" Liu Xingyan was taken aback when she heard that, "Cao Lu...is she really going to be detained here?"

"Cao Lu has a motive for committing the crime, and some important clues point to her. According to regulations, we have the right to detain her. If it is later proved that she has nothing to do with the case, we will release her."

Liu Xingyan knew that the police had definitely found out something, so she could only say, "If you find out that Cao Lu is innocent, please tell me, and I will pick the child up."

"it is good."

Liu Xingyan sighed and left helplessly.

"Contact the Suzhou police and ask them to go to the hotel where Cao Lu lives to obtain the surveillance video to see Cao Lu's whereabouts, especially on the night of the 3rd." Shen Yan began to order Cheng Haiyang to work.Cheng Jinsong added: "In addition, check the network IP of that hotel so that we can compare it with the suspect's IP."

"Yes." Cheng Haiyang wrote down the two things, then trotted away.

"Boss," Qin Kai walked in at this time, "I found something."
