Dr. Saleon
From Mass Effect Wiki
Dr. Saleon, later known as Dr. R. Heart, is a salarian geneticist who used to work on the Citadel. He came to Garrus Vakarian's attention during a C-Sec investigation, and is the subject of the Garrus: Find Dr. Saleon assignment.
Garrus tells Shepard that, a few years ago, he was assigned to investigate black market trading on the Citadel, and found there was an increase in the sale of body parts. C-Sec was unsure whether it was a lab selling organs illegally, or if a psychopath was dismembering people, yet the situation turned out to be more complex than this. Garrus ran a DNA check on a recovered turian liver, only to find the supposed 'donor' was very much alive. He later found that this turian had worked for a Dr. Saleon. Garrus inspected Saleon's lab, but there was no sign of any cloned body parts nor the machinery to grow them - "no salarian hearts, no turian livers, not one krogan testicle."
Running out of ideas, Garrus brought in some of Saleon's employees for a 'chat'. During the interrogation, one of the interviewees began bleeding and the C-Sec medics found that he had fresh incisions all over his body. It turned out that Saleon was using his employees - who were usually poor and desperate - as living test tubes: cloning their organs, growing them inside their own bodies, then removing them and selling them on, giving his employees a small percentage of the profits. If the organs failed to grow properly, Saleon would simply leave them inside the body, with dire consequences for the employees' health.
C-Sec went to arrest Saleon, but, knowing his operation had been discovered, Saleon fled, destroying his lab, snatching some of his employees and escaping the Citadel on his ship. Garrus wanted the Citadel defence forces to shoot Saleon down, but C-Sec overrode his order since the vessel was too close to the station, and Saleon escaped. The doctor later changed his name to 'Dr R. Heart' - "his idea of a joke" - and switched ships, buying and equipping the MSV Fedele to continue his research. Garrus tells Shepard that he has the transponder codes for Saleon's ship. Shepard agrees to investigate it, and Garrus asks to be taken along.
When Shepard's team boards the MSV Fedele, the commander finds test subjects (resembling Thorian Creepers) wandering the cargo bay. Dr. Saleon is in one of the compartments at the back - if Garrus is in the party he recognises the salarian, though Saleon tries to pretend he is innocent. Shepard can allow Garrus to execute Saleon or convince him that it would be better to arrest the doctor. Even if Garrus is convinced, Saleon refuses to be taken in, and is killed in the ensuing firefight.
