In May 1988 the government indicted six imprisoned radicals — Marilyn Buck, Linda Evans, Susan Rosenberg, Laura Whitehorn, Alan Berkman, and Timothy Blunk — for the Capitol and related bombings as a single "resistance conspiracy." The defendants fought a three-year political trial in Washington; in 1990, in a plea that dismissed charges against the three already serving long terms, Whitehorn, Evans, and the gravely ill Berkman pleaded to conspiracy and destruction of government property. Berkman, twice a cancer patient behind bars, was released in 1992 and became an AIDS physician; Whitehorn was released in 1999.
On his last day in office in January 2001, President Clinton commuted the sentences of Rosenberg and Evans, ending the case's active imprisonments. Buck, serving 80 years across the Assata escape, Brink's, and the bombings, was granted compassionate release in July 2010 with terminal cancer and died within a month — the organization's last political prisoner, freed twenty days before her death.
