The villain is trapped in the system and begs me to let him out [Moriarty who worries about the coun

When all the people came together, they found a figure tied up by five flowers lying horizontally on the ground under the dim moonlight, and they couldn't help feeling panicked.

"what's the situation?"

"This man is the real murderer of this series of serial murders. He just planned to attack me but failed." Du Ruoying explained.

Before she could hand over William's cell phone video, the murderer yelled hysterically: "I did try to hurt you, but that doesn't mean I have anything to do with those cases, does it? Can't I just because you're good-looking And lay hands on you?"

"It's you?!" Someone in the crowd recognized the identity of the attacker based on his voice.

"That's right, he is the waiter who entered the scene of the first crime with us." Du Ruoying turned on the phone's lighting function, and a pale light immediately projected on the other party, clearly illuminating his face.He was wearing a hotel work uniform, and the employee nameplate on his chest reflected a cold silver light, with his name imprinted on it——

Fang Yuhang.

"Am I crazy? Why would I kill them? I don't know them well!" Fang Yuhang said with his eyes wide open.

"Is it because they embarrassed me when I was working during the day?" Someone whispered.

"Don't talk nonsense, Xiao Fang is usually a very good person, how could he kill someone because of such a small matter!" Another person said.

"What's the matter? He just admitted that he assaulted the little girl, and there is a cell phone video to testify. You know the face, but you don't know the heart!" Everyone discussed.

"However, as he himself said, he is not familiar with this group of people," Police Officer Zhou said doubtfully, "Leaving aside his motives. You know, in the first murder case, the victim was designed to drink sleeping pills, The third murder case even used poison directly—if you don’t know the victim well, isn’t it easy to do?”

"Generally speaking," Du Ruoying nodded, "but as a waiter, it's not difficult to do this. After all, they need to deliver food and water to each guest room, and there are more or less opportunities to put sleeping pills."

"But didn't the murderer commit the crime around [-]:[-] p.m.? I heard from the police officers that the light in the victim's room suddenly went out at [-]:[-] p.m., which was captured by street surveillance. I was not there at that time." Proved, I was helping in the kitchen." Fang Yuhang said.

"That's true," a man who looked like a chef came out to testify, "It happened to be almost nine o'clock, and I heard a bang from the back kitchen, so I ran to see it. It was broken. Afterwards, we cleaned it together for a long time, about half an hour before and after, and Xiao Fang was always there."

"That can't be an alibi." Du Ruoying shook her head and raised her hand, "Look at the window of that room, Room 8169, which is the room that Will and I booked. There is no one in the room now, and the lights are on. If it is on, the light will automatically turn off after 3 minutes."

"You said there was no one inside?"

"If Officer Zhou doesn't believe it, he can send a police officer on duty at the scene of the first crime to take a look." Du Ruoying took out her mobile phone and looked at the countdown, "There are 2 minutes left."

Officer Zhou made a phone call immediately: "Xiao Liu, go to room 8169 next door to see if there is anyone in the room."

After a few seconds, there was a response from the other end of the phone: "No one, what's wrong?"

"It's nothing, you stay in the house, don't go yet."

"Row."

"There are 40 seconds left." Du Ruoying told the time again, "20 seconds, ten seconds, five seconds... three, two, one."

As soon as the voice fell, the light in the window of Room 8169 went out.

Officer Zhou immediately asked the other end of the phone: "What happened, did you trigger some mechanism?"

"I've been standing at the door without doing anything. I don't know why, but the light suddenly went out... Hey, could it be sand?"

"Sand? What sand?"

Just when everyone was at a loss, Du Ruoying said: "Yes, it's sand - I filled the card slot for inserting the electric card at the door with sand in advance, because this card slot is photoelectric, so Filling with sand can also play a role similar to plugging in a power card. As time goes by, the sand slowly leaks down the pores at the bottom. According to my experimental results, it takes up to four to 10 minutes, and the remaining sand will be reduced due to It’s too low and loses its barrier effect, causing the room to lose power—as if someone had pulled the card—so the lights in the room went out.”

"I see. No wonder the scene of the first crime was sprinkled with sand everywhere, just to prevent the sand on the ground at the entrance from looking too obtrusive?" Officer Liu on the other end of the phone suddenly realized.

"Indeed, in this way, the nine o'clock to 09:30 to the alibi is meaningless."

"But when you entered the scene of the crime as the first discoverers, wasn't the electric card plugged into the card slot and turned on?"

"That's a simple trick - just cut off half of a complete electric card, fix the other half on the card slot with double-sided tape, and pretend it's fully inserted. The illusion of power is also the same. It's easy to create. We just see the victim in a state of electric shock, and the electric toy is connected to the socket and buzzing, so we think there is electricity in the room. But usually that kind of toy can't be designed only as The plug-in type is used because it is too dangerous to use, and it is usually a charging and plugging type. As long as it is fully charged in advance, it will not affect its operation when the socket fails to supply power."

In the crowd, someone made a malicious ridicule: "The little girl understands it quite well, it seems that she has used it a lot..."

Before he could finish speaking, a pair of extremely cold gazes came to him, like an invisible sharp knife firmly pressed against the man's throat, so startled that he suddenly fell silent, for fear that if he said one more word, his throat would be stabbed pair wear.

Police officer Zhou, who didn't know anything about this, continued to question Du Ruoying: "In this case, why did you mention this possibility now? Do you know how misleading our investigation direction is? ?”

"I really didn't consider this possibility before," Du Ruoying replied honestly, "After all, when Fang Yuhang entered the scene with us, he said something like that——"

"What?"

A policeman next to Police Officer Zhou realized something, opened his confession and recorded: "He told Officer Du not to go there first, and he had to cut off the electricity in the house first, or even Officer Du would get an electric shock. Said to wait for him to take the room card from the sensor switch first, and then go in to save people."

"Yes, these words made us have a preconceived impression of 'there is electricity in the room', and it covered him to take back the room card used for concealment." Du Ruoying said.

"But there is a premise for this method to work—the victim happened to live in an old-fashioned interesting room facing the side where street surveillance was filmed—but the room was chosen by the victim himself. If he becomes self-willed in the middle, he can even switch with other companions at will. room." Police Officer Zhou thought, "How did such a coincidence happen in the end, such a murderer's intention?"

"I was stuck on this issue for a long time before, and I only figured it out after Brother Xian reminded me." Du Ruoying replied, "Actually, if the murderer was on duty at the front desk when the victim booked the room, he would naturally be able to control and guide everything." , the murderer only needs to tell them that there are no other rooms to limit their choice, and the advantages and disadvantages of these rooms are obvious-only two rooms face the sea view, and the view of one of them is blocked The experience is better, and Wu Chi will naturally choose the room with the best experience."

"It was true that Xiaofang was on duty when they booked the room, and they were looking for Xiaoxia to change shift temporarily." A waiter recalled.

"These are just your conjectures!" Fang Yuhang argued frantically, "It is slander to accuse me of murder without evidence!"

"If you want evidence, then I'll give you evidence." Du Ruoying took out a transparent evidence bag and held it up high. Inside was a half room card with a piece of double-sided tape stuck on it. Too many, I have a chance to go to the front desk to get the AED. I searched along the most likely route you took, and I found this from the dustbin near the lobby. It can be seen that you wiped the face of the card The fingerprints were wiped thoroughly, but I wonder if any DNA residues can be found on the glue surface?"

"Ah, I remember that card. It was an electric card that was scrapped a few days ago. I was about to throw it away. Brother Yu happened to be packing the trash, so he took it away." A young waiter testified.

"Look, that's right." Du Ruoying said, "As for the second case, it's even simpler. The murderer just needs to call the victim, and as a waiter, he can find any reason to ask the victim to come to the front desk." ——For example, I forgot to put a disposable toothbrush in the victim’s room, and the victim needs to come to the front desk to pick it up—the victim will obediently enter the elevator.”

"But, getting into the elevator doesn't mean we'll meet each other, right?"

"We will definitely meet each other. As long as the murderer is on another floor in advance, put something on the door of other elevators, occupy the elevator, and only one is left for the victim, he can successfully lure the victim to take the same elevator with him. The victim Naturally, the waiters who were unfamiliar in the elevator were defenseless. Unexpectedly, he was killed in a narrow metal iron cage. After killing people, the murderer stopped the elevator on the equipment floor or office floor with the least traffic and escaped. Avoid encountering others, and restore the elevators to their original state, that’s all.”

"Even so, it is very likely that other people will enter the elevator? At that time, what should we do?"

"At that time, the statement recording was over. The police mainly concentrated on the first crime scene and the entrance and exit of the hotel. The hotel staff and guests were also resting. No one was using the elevator. The murderer had a high success rate," Du Ruoying said. .

In fact, she didn't know that at that time, if she couldn't wait for the elevator for a long time, if she didn't choose to take the stairs, but waited until the victim came, and walked into the special elevator leading directly to death with herself, what would happen in the end? What.

Will they make it down to the first floor safely?

Or, the person who leads to the end of death——

Will one be added?
