The FBI's pursuit of the remnant ran three more years. Mark Cook, a Black prison organizer convicted for the Sherman escape and the Tukwila robbery, received consecutive terms stacked toward life; Rita Brown, the group's out-lesbian ex-convict cadre, was captured in Seattle in November 1977 and sentenced to 25 years, serving federal time including Alderson; Therese Coupez and Janine Bertram were taken in the March 1978 round-up that effectively ended the organization; and John Sherman, recaptured, escaped once more in 1979 and remained a fugitive until 1981, ultimately serving into the 1990s.
The prosecutions were framed by the state as ordinary armed-robbery cases, but the defendants — who called themselves prisoners of war of the class struggle — were adopted by the era's political-prisoner networks, and their trials became forums on Walla Walla, prison labor, and the conditions that had built the Brigade.
