The stamp is something left over from an inpatient hospital program. In some other program RELEASED used to mean a client was set free. Now it means a client is dead. Nobody wanted to special-order a stamp that said DEAD. The caseworker told me this a few years ago when the suicides started back up again. Ashes to ashes. Dust to dust. This is how things get recycled.
