Biography
John Sherman met Ed Mead at McNeil Island federal prison in the late 1960s and later joined the George Jackson Brigade. He was wounded and captured during the January 23, 1976 Tukwila bank robbery, freed from custody by Mark Cook on March 10, 1976, and recaptured with Therese Coupez and Janine Bertram on March 21, 1978. Sherman was convicted in federal court in July 1978, escaped from USP Lompoc in March 1979, was recaptured in Golden, Colorado, on December 17, 1981, and was released on parole in 1998. He later became a spiritual teacher.
Prison release narrowed to April 1998
His own foundation biography identifies the distinctive 1976 capture and escape, 1978 conviction, 1979 escape and December 17, 1981 recapture, establishing that this is the same former Brigade prisoner rather than a politician or intelligence official with the same name. It gives April 1998 as his parole release from prison, improving the previous year-only endpoint to month precision. It separately dates the end of parole supervision to August 2007; that is not another prison release. Any displayed day counter is calculated from a month placeholder, not an exact documented custody total. John and Carla Sherman's foundation biography.
The article reports Sherman freed by the Brigade on March 10, 1976 and still underground when he called a Seattle reporter on May 11 to identify his signature on a March 27 statement. It also reports his inclusion in the May 19 conspiracy indictment. This confirms the existing escape endpoint; it is not a judicial discharge or evidence of renewed imprisonment on May 11 or May 19.
