suicide smock
n.— «A year-and-a-half-ago, Grove tried to kill himself, according to court documents. For that reason, the Boulder County Jail has placed him on suicide watch, and in his mug shot—the one with his hair standing wildly on end—he is wearing what is known as a “suicide smock,” a garment that can’t be made into a noose.» —“Damm case: Kids next door?” by John Ingold in Lafayette Denver Post (Colorado) Mar. 12, 2007.
