DIED. Mitch Snyder, 46, indefatigable champion of the homeless; apparently by suicide; in Washington. Snyder was found hanged, with an electric cord around his neck, at the Community for Creative Non-Violence shelter he helped establish. Police attributed the suicide to his despair over a failed relationship. On the eve of the 1984 presidential election, Snyder defied death and Ronald Reagan in a 51-day fast that ultimately led the Government to donate an abandoned federal building for a showcase shelter. Martin Sheen portrayed him in the 1986 CBS television movie Samaritan: The Mitch Snyder Story.
