Immortal Sin

Immortal Sin is a case featured in Criminal Case, appearing as the one-hundredth-fifth case of the game and the forty-ninth case of Pacific Bay. It is the fourth case to take place in Innovation Valley, a district based in Pacific Bay.

Plot
The victim was a former trophy wife-turned CEO named Teresa Turing, who was suspected of murder four cases prior to the events of this case. Teresa was found stung to death by jellyfish at Meteor Systems' underwater laboratory. As Teresa was pronounced dead by authorities, Karen Knight succeeded Teresa as the firm's CEO.

Karen deduced Teresa's experiments and research of human immortality dangerous, so she ordered Meteor Systems employees to shut those departments down before things got out of hand, so Amy Young and the player gathered enough evidence to incriminate Teresa's mother, Greta Meduse as the killer.

Amy was stunned when the player found out that Greta killed her own daughter, in which Greta was unhappy about what the player came up with. In spite of Greta's false arrest accusations, Amy has enough evidence to bust Greta thanks to the player. Greta felt that Teresa was obligated to share the youth with her, in which Teresa kept her immortality experiments to herself, something Greta hated since she doesn't tolerate her daughter to keep secrets. Amy informed Greta about Teresa's terminal disease (in which Yann Toussaint found out during the investigation, which motivated Teresa to start her dangerous immortality experiment), something Greta never knew, and felt that the terminal disease was something Teresa shouldn't hide at all. The player had enough of Greta, so they shipped Greta to face Judge Dante.

Judge Dante deduced the murder method monstrous but Greta defended herself by telling the Judge that Teresa hid her terminal disease from her. Judge Dante felt Greta took punishment to unacceptable levels, and in spite of what Greta said, Judge Dante made it clear that he was the one holding the judge's gavel, allowing him to sentence Greta 20 years in jail.

Chief Marquez wanted Amy and the player to ensure Karen that she had full oversight on all of Meteor Systems' research given the horrendous events of the case. Moreso, Chief Marquez ordered Amy and the player to subdue a break-in hours after the case.
