Chapter 266 River Poison ([-])

At ten o'clock in the morning, Liang Xi felt that the case might be more troublesome than he thought.There are three ex-convicts in the kitchen, and the waiter in charge of catering is the girlfriend of an ex-convict.There is an ex-con in the delivery department, and the delivery server is the ex-con's brother.The chef responsible for the borscht soup has been charged with six counts, including negligent injury caused by poisoning.

At first it felt like there were no suspects, but now it feels like everyone is a suspect.The restaurant manager explained that the hotel does employ ex-criminals, but based on the experience of each branch, the possibility of ex-convicts recidivating is very low.And it is easy for them to regard the hotel as their home. At the same time, they know very well that this is one of the few companies that will provide themselves with normal jobs.Restaurant managers specifically stated that they would not hire violent ex-cons.

Not only Liang Xi, but Ke Lante and Seymour began to make fuss about the staff after getting the staff information.From the current point of view, the three people all tended to be poisoned by a staff member who had access to borscht.Due to the accident of Hannah's stay in the hotel and the rarity of tetrodotoxin, it shows that the poisoner was ordered by someone.

Three detectives worked on the subject for a day, visiting, auditing accounts, questioning individually, and learning about the background.In desperation, the three sat together to share information at dinner, and they found that no real suspect could be found.They could not find any issues with the suspect's money and accounts, or any connection between the suspect and Hannah.They were successfully led astray by the clues that the assistants focused on submitting.Liang Xi, who was mentally prepared, was not spared, and it was right to start with high suspicion.

The inspection department provided a report, and the test results showed that the poison in the borscht soup was close to 3 mg. They definitely told the three detectives that this was a high-end product, and ordinary people could not touch it at all.Under normal circumstances, only medical companies and research institutes related to medicine have high-purity river poison. The current market price of high-purity river poison is [-] US dollars per gram.

Apparently the theme of their work day today is wrong.

Could it be that Ryan, Jack and Jeff in room 2121 did it?According to the description of the three, the food delivery man brought the cart directly to Hannah and lifted the cover.Hannah drank the borscht first, then the food, and left the borscht untouched after that.

Only once did the borscht go out of sight.The waiters on the second floor deliver the food to the food delivery department on the third floor through a small elevator.Could it be that someone intercepted the elevator?Seymour first thought of this possibility, and went to check the small food delivery elevator led by his assistant.Liang Xi and Ke Lante didn't move. They knew the structure of the small elevator. They could only move on the second and third floors. It was closed on all sides. It made a lot of noise when it was started, and it was extremely difficult to inject poison while the elevator was running.

During the exchange between the two, Currant put forward a hypothesis that after Hannah was sent to the hospital, there was a vacuum in room 2121.Maybe it wasn't the borsch that poisoned Hannah, it was poison because someone added river poison during the vacuum.Liang Xi disagreed, because the corridor monitoring showed that no suspicious person went to room 2121.Ke Lante said that someone must have gone, Jack and Jeff both ordered food, and the person who delivered the food to Jack and Jeff should be the most suspicious person.

Liang Xi didn't think it was necessary to cover up and frame Borscht, but Ke Lante thought there was a special reason.Liang Xi's opinion is hackers, and some hackers used surveillance, because after a comprehensive analysis and understanding, only if the video captured by the surveillance is falsified or the statements of Hannah and others lie, the suspect can carry out the poisoning.The two had different views, but respected each other and did not argue on this issue.

Liang Xi thought for a long time after dinner, and contacted Sierra: "Hey, do you want to work overtime?"

Sierra was already in a cold sweat when she answered Liang Xi's phone call, and she was a little apprehensive when she heard that she was working overtime. She just lost a lime, and who was she after?But Sierra didn't dare not take it, what if the marble was exposed?What if Thresh is exposed?

Serra asked, "Is it legal?"

Liang Xi said: "For cases where the victim is unwilling to report to the police, all the monitoring has been bought out by my employer. It cannot be said to be legal, but it is definitely not illegal." Drug surrender is a criminal case after all, and it is a bit too much to say that it is legal.

Serra responded: "Okay, I'm free for a day or two, call me or email me if you need anything."

Liang Xi: "Thank you. I'll send you some surveillance videos. I think the videos may be tricky. Check them out for me when you have time."

"OK." Sera didn't talk much, but she was straightforward.Do it if you can, refuse if you can't, and never give in.

……

Because of the company's acquisition by Bobby, Sierra focused on the Clement Group's industry, and she also moved to live in London.The group company provided the diamond company with a small villa as a workplace. Since the diamond company had only one person, the small villa became the place where Sierra worked and lived.

When Liang hit the phone, it happened that Chris Thresh was asking Sierra to steal the information, and said to Sierra, "Help him deal with it first."

Sierra's keyboard and mouse were double-moved, and the skillful and precise technique quickly analyzed that there was no problem with the video.Serra said: "The video is fine, it is all video taken by the corresponding monitor, but the time has been tampered with. Look at the surveillance in the corridor."

The food delivery man came out of the elevator with a trolley. The elevator monitoring was empty, and it was transferred to the corridor monitoring.A delivery man pushed the cart out of the elevator and pushed it to room 2121.

Thresh asked: "Isn't the food delivery person in the elevator captured by the surveillance?"

"Maybe not." Serra said: "The elevator was also controlled. Didn't the food delivery staff send it to the 21st floor... Have you seen Mission: Impossible 4? Using a fake room number and cooperating with the elevator to realize the identity replacement." A To go to room 2121, in fact he only reached the 20th floor. The number on the 20th floor has been replaced with the 21st floor, and A actually went to room 2021. B pretends to be A and goes to room 2121.After finishing the work, A also helped B to top the bag.

Thresh looked at Sera with strange eyes: "You are Sera the hacker, you are not Liang Xi the bastard."

Sera said helplessly: "Technically speaking, this person is Shen Hai. I helped Shen Hai do similar things. A year and a half ago, Shen Hai contacted me and said that his left hand was injured, and he hoped that I could do him a favor. He explained to me He also provided me with the software he specially designed for this operation. The software is like the master console of an office building, which can control all elevators, power supplies, security systems and other networked devices.”

Thresh asked: "Are you taking jobs in private?"

Serra said, "This... I just want to test the software he wrote."

Thresh asked, "And then?"

Serra said, "That's a trap."

Shen Hai was working in New York, USA, but he did not expect that the police who had received the news had arranged a net to wait for them.A thug accomplice was arrested by the police.The accomplice exchanged the identity of a tainted witness in exchange for assisting the police in arresting Shen Hai.Since the accomplice had property, a wife and children on the surface, he could run away as a monk but could not escape the temple, so the police released the accomplice. "

This friend fully carried forward the spirit that brothers are brothers and women and children are clothes, and truthfully explained the situation to Shen Hai.So a bold plan was brewed, and Shen Hai deceived Sera to the United States, claiming that the purpose was to expose an organization that laundered money in the name of charity.And provided Sierra with the software to control the entire building.

The deep sea project went well, and the police quickly cracked Serra's location.But Shen Hai never expected that Sierra was not only a nerd girl with computer talent, but also a hacker of the orphans. At that time, she was accompanied by the all-round thug Lime who was traveling to the United States.And the team that caught Sierra was just a white-collar crime investigation unit.

The suburban house where Serra lived was set alight, effectively buying time and destroying evidence.When the police arrived, Sera and Lime had already entered the forest. They walked more than [-] kilometers, crossed half a mountain range, and turned over more than ten high mountains.During this period, they also successfully covered up their traces, so that the police could not know their specific movements.

Seven days after Serra's escape, the Deep Sea accomplices returned home to Austria from the United States.That night, someone knocked on the door, and the accomplice opened the door. The masked man raised his gun and asked, "Where is the deep sea? There is only one chance."

The accomplice said that he didn't know what he was talking about, and the masked man said: "Xingkong sends his greetings to you." He shot and killed the accomplice.The accomplice's wife ran downstairs when she heard the movement, and screamed when she saw her husband lying in a pool of blood. The masked man shot her dead and spared the ten-year-old child who followed his mother to the door.

Not long after, Sera, whose screen name is Xing Kong, received an email from Shen Hai: "You shouldn't have killed his wife."

Sela replied, "Do you need war?"

Deep Sea replied: "The dead are gone, I like peace." He didn't know Sera's identity, but Sera knew the orphan of his accomplice, so he dared not declare war.

Over the next year or so, the two had no contact.

Sera: "If I help Liang Xi, I will probably be identified by Shenhai. Only I know that Shenhai has such a set of software. Unless I am familiar with the software, even a super computer expert will find it difficult to find the problems in the video." Last time Sera guessed that there is no problem in monitoring Isa's mobile phone in the deep sea. One reason is that many hackers can monitor Isa's mobile phone, but the deep sea has simpler, faster and more effective means to monitor Isa's mobile phone.One reason is that many technical personnel of the police worked together to study Isa's mobile phone.

Thresh said: "It's not that Shen Hai doesn't want revenge, it's that he has no chance of revenge. Although you may be exposed because of this, it is also an opportunity to destroy Shen Hai. Liang Xi is a dog that is very accurate in biting people. Give me some time to think about how to use a knife to kill people." Yes, if the person hasn't been found yet, please ask Dao to help us find him.

Serra: "Does it have to be a war?"

Thresh said: "Control your own destiny, don't have a fluke mentality towards the enemy, and don't expect them to have mercy. I'm not worried that Liang Xi won't find out the information, but I'm a little worried about Liang Xi's safety. He doesn't seem to know the investigation Who is the target?"

……

The investigation on the first day made no progress, and Ryan couldn't sit still. He called Liang Xi at seven o'clock in the morning, hoping that Liang Xi could find some clues today.One reason is to get Liang Xi to get up and pee to work, and the other reason is to euphemistically tell Liang Xi that there is not much time left for Liang Xi and the others.However, Liang Xi is not an employee after all, and there is no entrustment agreement, so threats and bribes are not effective, and can only be coaxed to make Liang Xi work more.

After washing up, Liang Xi took the elevator to the underground parking lot, and saw Sierra leaning to one side in a sweater and hood.Sierra made a silent movement, took out a notebook from her pocket, and opened the first page: "The power-on status of the mobile phone may be tapped in a targeted manner." This is a hotly debated topic on the Internet, and many people have done experiments. , Some words are mentioned in daily chat, and after opening some apps, you will find that the products recommended by the app are related to the words you mention every day.

Serra turned to the second page: "Give me the phone."

Liang Xi handed the phone to Sera, and he had complete trust in Sera.Selah squatted against the pillar, skillfully placed the laptop on her lap, and connected it to the mobile phone. After a while, Selah took the notebook and wrote: "Your mobile phone has not been tapped."

Flipping the page of Sierra's notebook, he wrote: "But the location has been hacked, and the other party can check the location of your phone at any time."

Liang Xi took the notebook and pen to write: "Since there is no bugging, why can't we talk in language?"

Serra looked at the notebook, thought for a while, and pointed to the Beetle.

After getting into the car, Sierra explained: "I think there is something wrong with the video you sent me, but I couldn't find out why. So I forwarded the video to a netizen named Xing Kong. She was sure that it was caused by the deep sea. Why. Anyway, if you don’t understand, I won’t explain it.”

Liang Xi didn't think it was an insult, and said, "Check it out, who lives in room XX21." To change the civet cat to the prince, the civet cat must first be needed.The food delivery man delivered them the civet cat, which is the food ordered by the food truck and Hannah.

Sierra admired her in her heart, and jumped to this step so quickly.The suspect can change the number of floors in the floor, the suspect can change the floor displayed by the elevator, and the food delivery staff may not notice the difference between the floors.But the delivery man will not deliver the wrong room number.Because room 21 is in that location.

There are five floors with the same layout as the 21st floor, and there were residents at the time of the incident.Two of them checked in in the afternoon of the incident, shortly after Hannah booked the hotel, a man and a woman, the man named Quick, 21 years old, American.The woman is Homer, 27 years old, French.It is difficult for hackers to tamper with this part of the information, because now is the Internet age, after passengers register at the main station, the data is not only saved, but also transmitted to the server for filtering.Assuming the guest's fingerprint or face scan matches the alert signature set by the server, the server will immediately notify the police.If it does not match, it will also be stored in the server as data.

Liang Xi pointed at Quick: "Fake identity?"

Sera asked in surprise, "Why?"

Liang Xidao: "Looking at the dress of Quick in the customs photos, he should be an American college student traveling poorly in Europe during vacation. Generally speaking, it is impossible to live in a luxury hotel. You can verify whether Quick has no other expenses, such as bars, such as Fees for swimming pools and such.”

Serra said, "No."

Liang Xi said: "Let's assume that Quick is a low-key rich college student. After he stays in the hotel, he doesn't go to the hotel bar, doesn't use any hotel facilities, and doesn't even eat in the hotel. Then why does he stay in this hotel? You Check 2221's room card unlocking records, I believe that Quick is in the room most of the time."

After querying, Sierra said: "That's right."

Liang Xi said: "It should be him. But is he pretending to be Quick? If so, he himself will avoid the camera as much as possible, or use masks, sunglasses and other items to cover recognizable parts of his body."

According to the check-in time, Serra found several videos of Quick, and found that, as Liang Xi said, Quick was always wearing a mask and gloves, with his head slightly lowered, and he never raised his chest to look up.

Liang Xi still feels wrong, and this feeling is usually because his current judgment conflicts with a previous judgment.Liang Xi decided to ask Sera to assist him in sorting out the case.
