Katherine Ann Power (b. January 25, 1949) is an American ex-convict and long-time fugitive, who was placed on the Federal Bureau of Investigation's Ten Most Wanted List in 1970, along with her accomplice Susan Edith Saxe, a fellow student at Brandeis University. The two participated in robberies at a Massachusetts National Guard armory and a bank in Brighton, Massachusetts where Boston police officer Walter Schroeder was shot and killed by one of their accomplices. These acts were to support protesting the war in Vietnam. Power remained at large for 23 years. In 1993, Katherine Ann Power negotiated a surrender with authorities and ended 23 years of hiding. Negotiations were carried out through her attorneys Steven Black, a public defender, and Rikki Klieman, a prominent Boston lawyer. On September 15, 1993, she pleaded guilty to two counts of armed robbery and manslaughter in Boston. Power was sentenced to eight to twelve years in prison for the bank robbery, and five years and a $10,000 fine for the National Guard armory crimes. Additionally, judge Robert Banks of Suffolk County Superior Court imposed a probation condition that Power could not profit from her crime. Power appealed this portion of the sentence on First Amendment grounds, but the Massachusetts Supreme Judicial Court rejected the argument and the U.S. Supreme Court denied certiorari.
