Swiss police arrested several people after the first use of the “Sarco” suicide capsule in Merishausen. Prosecutors opened criminal proceedings for aiding suicide. The deceased was a 64-year-old American woman with a compromised immune system. Florian Willet, co-president of The Last Resort, and three others were detained. The capsule, designed by Philip Nitschke, causes death by releasing nitrogen gas. Switzerland’s legal stance on assisted suicide attracted the use of the device.
