According to Zurich’s justice department, euthanasia cannot be denied simply because a person has been sentenced or is serving their sentence behind bars.

Swiss law tolerates assisted suicide when patients commit the act themselves and helpers have no vested interest in their death. It has been legal in the country since the 1940s, and assisted suicides represent around 1.5% of the 67,000 deaths recorded on average each year.
