Does Hypnotism Even Exist? Secret Knocks the Door

Science of Elevator is a case featured in Criminal Case, appearing as the fourth case of the game as well as the city of Alpha Bay, and the fourth one to take place in the Street Valley district.


While walking around the streets, Susan and the player heard a loud sound as if something had gotten shattered in pieces. They went inside a company named Goldberg Incorporated, beside which they were standing at that moment, assuming the sound came from there. They went to the top floor only to find a crashed elevator with a dead woman inside and it seemed like someone just tore her up.

The liftman, Luka Field identified the victim as Serena Goldberg, the CEO of Goldberg Incorporated and said the victim was very generous and serious at work. After talking with him, the team soon found two more suspects, one was the victim's business partner Emily Taylor who said it was good to have a tough rival as the victim and the other suspect, Rita Goldberg, who was the victim's daughter didn't react much.

Eva was sure that the modified elevator was the murder weapon as it was programmed to go upwards with a great speed, which made the victim feel a lot more weight than her own as it caused a lot of force on her body, enough to tear her up. The crash also made the death quite obvious. Counting the killer used a term of physics, Eva confirmed the killer knows physics.

Soon afterwards, the team flagged Boris Cooper as a suspect who was the victim's financial advisor. He was annoyed with the fact that the victim was letting her company go bankrupted for an unknown reason. Shortly after the team could understand the reason as they flagged Street Riders second-in-command, Fredo Mancini as a suspect for threatening the victim to kill her daughter if she hadn't given them money. Fredo said the victim gave them as much as they wanted. On the other hand, Luka was exhausted because the victim wanted to fire him without a single reason. The team also discovered that Emily wanted to buy Goldberg Incorporated to get more profit but the victim didn't agree to sell her the company anyway.

Soon after, the team discovered that Rita had become the CEO of the company and wanted to sell that to Emily. On the other hand, Boris threatened to make the victim step down in order to protect the company from getting bankrupted while Fredo took up a fight with the victim because she didn't agree to give a single dollar anymore. The team, however, after searching the elevator again, got enough evidence to arrest Rita for the murder of her murder.

Though Rita tried to deny, she had to confess after showing the proofs that she had killed her mother. Rita stated that she was exhausted at the victim for letting the company go bankrupted as she was the successor of the company. After she came to know that the company fell in a financial crisis and that Emily was willing to buy it, she hit upon a plan to eliminate her mother to get the money of insurance and of other things. So she sabotaged the elevator to kill her mother. As she finished saying with a smile, Susan got annoyed and said why she was doing it, which led Rita burst into tears as she was doing it to save her daughter. At the trial, Judge Powell sentenced her to 15 years in jail with no chance for parole.

Post-trial, the team confronted Fredo to give the money back, which he did. But surprisingly, the money was all fake which made both the team and Fredo astonished. Fredo claimed all the money were real and that he didn't know anything about how it became fake. Then, the team helped Emily to buy the Goldberg Incorporated thanks to a helpful Boris who wanted to work with Emily. Then they were informed by Chief Prince that a Detective from Pacific Bay PD named Habib Romanov wanted to meet with them. When the team met him, he said he came to Alpha Bay to discover why a part of Street Valley was declared restricted area and why most of the people didn't know anything about it. Susan also said it was a mystery and something bigger might got hidden here. Habib then said that he would investigate further and promised to help the team by providing the information about his investigation.
