Li Jing, who put down the phone, looked preoccupied, and the patient just pushed the door in at this time, and I could only swallow the problem back into my stomach.

"You've guessed it." After the patient left, Li Jing said as he cleaned up the table.

"Huh?" I don't understand, what am I right?

"On that day, the ticket inspector did not deal with the water left on the floor of the hall, so the ticket inspector in the screening hall fell and injured himself, so the audience was free to enter and exit before the opening of the movie in front of us. This is what the Xiao team found when they looked at the transcript again today, but this person did not have the time to commit the crime at all, and the surveillance video confirmed that this person had been helping at the theater bar before checking the ticket, and then slipped and directly called the ambulance to send him to the hospital, so the suspicion was ruled out. However, this clearly explains how the body was transported into the screening room. Li Jing explained.

"Is that the suspect really the one who watched the movie that day?" My conjecture was confirmed, and I was on my feet.

"Not necessarily, although there were no inspectors at that time. But the manager of the theater said that it was snowing that day, and there were very few people going to the theater, so he asked the audience to tear off the paraple and put it on the table at the ticket office. He was afraid that someone would evade the ticket, so when he accompanied the ticket inspector to wait for the ambulance on the lounge chair in the hall, he kept glancing at the ticket gate, and he didn't find any suspicious people. ”

"Then our problem is back to square one, and we still haven't figured out how the corpse got into the screening room!" I sat back in my chair dejected.

"If you die before entering the screening room, you can actually enter the screening room without being noticed." Li Jing patted me on the shoulder comfortingly, "After death, the heart stops beating, the blood no longer circulates, but piles up corpse spots under the body. Unless it is a car accident such as the body subjected to severe impact and bleeding to death, the victim of a knife will not show too many signs of bleeding after death, and it will not appear in the movie theater covered with blood as you imagine, and the corpse also shows traces of being treated, and the treatment method is very skillful, and the forensic doctor infers that the murderer has had medical experience. In addition, the forensic doctor's side deduced from the shape of the corpse spots on the buttocks and back that the deceased had been in a sitting position for a long time before being placed in the top darkroom. Therefore, it cannot be ruled out that the body once sat in the audience in the screening room. ”

After listening to Li Jing's explanation, I couldn't help but feel a chill behind my back, I really didn't know that the unlucky guy was later sitting on the chair where the murderer had placed the body.

Because of listening to Li Jing's description of the corpse, I really couldn't eat anything for dinner, and when I watched Li Jing on the other side feast, I could only suppress the unpleasant reaction in my stomach with lemon juice on the other side. Full of forensic terms, I didn't dare to go home alone, Li Jing said that I wanted to go to the theater again, so I could only go with him. No matter where you go, two people are better at ease than one.

Walking into the cinema, the staff pulled down their faces as soon as they saw us, probably because of the case. Li Jing asked the bar attendant about the theater manager's office, and was told that the theater manager left early today, and asked them about the location of the monitoring room, and the theater security guard denied that outsiders were not allowed to go to the monitoring room without the manager's permission. In a fit of rage, Li Jing called Team Xiao.

Ten minutes later, Li Jingshun and I entered the monitoring room, and when the little security guard left, he muttered, "The police have been checking for two days, and they haven't found anything, what else are you looking at, do you really think you're a detective?" Kook. ”

Li Jing stopped the security guard as if he didn't hear it, and then began to fiddle with the machine in front of him: "Brother, I have to ask you to do me a favor for a while, you give me the phone, I will call you later, you stand in my position and wave at the monitor, until I ask you to change positions." ”

Although the little security guard was reluctant, he still cooperated with Li Jing to play treasure under the outside monitoring for a long time, and he could feel the surprised eyes of the people around him through the screen, and it was estimated that now the security guard hated Li Jing to death. Li Jing wanted to connect the monitoring to his mobile phone and continue to observe after he returned, but the system told him that the monitoring device had been bound to an account and could not let him log in with his mobile phone.

Li Jing looked at the machine suspiciously: "Xiaozhi, help me check how many mobile phone accounts can be bound to this device?" ”

I looked for a machine qì model,Asked Du Niang,Cashback monitoring of this model because it's an upgrade of the old version,You can bind up to 3 accounts。 I decided the result in front of his eyes, he glanced at it, and asked the security guard: "Little brother, who is generally responsible for your surveillance inspection and deletion?" ”

"The manager and the captain of our security department!" The little security guard replied to Li Jing angrily, maybe he was too embarrassed and angry just now.

After listening to this, Li Jing's eyes seemed to light up, and he picked up the phone without thinking: "Shi Hao, I'm Li Jing, help me quickly check how many accounts I have registered for this monitor, and I'll send you the model in a while." ”

As soon as I heard Li Jing call me the name of the male god, I quickly leaned my ears over, but the other party seemed to be sleeping, and his voice sounded vague.

"Don't be tomorrow, now hurry up and help me check, wait for your call," After speaking, Li Jing pressed the hang-up button, in exchange for my angry eyes. The little security guard saw that there was nothing wrong with him, and pushed the door and went out.

The waiting time was very long, and I felt like I was about to fall asleep, when Li Jing's phone rang suddenly: "Shi Hao, have you found out?" Well, can I find out the registered address? Is the registered address in the theater? Is there any other information? For example, can I find out which mobile phone was registered? See if you can find the registrant through the guò mobile phone information. Well, if there is a message sent directly to Team Xiao in a while, I will ask him for it tomorrow. “

After hanging up the phone, and meeting my questioning eyes, Li Jing handed me the coat: "Go back, talk while walking." “

"There is indeed a third person who has registered a mobile phone for real-time monitoring in the APP of this monitoring brand." Walking out of the cinema, Li Jing began to help me solve my questions little by little, "But Shi Hao said that the IP address registration information of the three accounts is in the theater, so there is no way to lock the suspect." I'm now asking him to try to locate the three phones that use this feature and lock on to the suspect. ”

"Then what kind of treasure do you let the little security guard stand outside?" I still have one more question that I haven't answered.

"I'm looking at a surveillance blind spot." Through the warm glow of the street lamp, I could clearly see the expression on Li Jing's face that hated iron but not steel.

"Even with 360-degree surround surrounding, there are still blind spots where they cross, and public places like movie theaters are generally only used for fire escapes, service desks, bars, and other places where money is collected. If the murderer wanted to carry the body into the screening room, he had to avoid all the surveillance points in order to enter. ”

"Then I can only ask Brother Shi Hao to find the third person quickly." My admiration for Fang Shi Hao deepened again.

"Shut up, he's a programmer!" Li Jing began to re-tie the scarf around his neck.

"You seem to be jealous of him, don't you?" I laughed at Li Jing.

Li Jing was only concerned about tying his scarf, and he was not ready to talk to me at all, so I had to quiet down and walk home with him side by side.
