Florian Willet, the president of the organization "The Last Resort," remains in custody in Schaffhausen, Switzerland, amid suspicions of intentional homicide.
This follows the death of a 64-year-old American woman in a controversial suicide capsule, known as Sarco, which was supposed to facilitate a peaceful death by nitrogen inhalation.
However, forensic evidence suggests the woman may have suffered neck injuries, raising questions about the cause of death.
While Willet was arrested along with others, he remains the only one still detained, as authorities investigate the possibility of foul play.
The case has sparked a broader debate on assisted suicide and the ethical implications of such devices.
Critics argue that the ease of access to these capsules could lead to misuse, while supporters claim they offer a dignified option for those seeking to end their lives.
