Biography
David Johnson was one of the San Quentin Six prosecuted for the events of August 21, 1971 at San Quentin. He was acquitted of murder and convicted of assault on a correctional officer. A contemporary Guardian report says Judge Henry Broderick suspended his sentence and placed him on three years of probation because of time already served awaiting trial. This disposition was not an additional custodial term; the report does not establish his actual physical release date.
Post Amerikan (March 1974, p. 16), reprinting a Liberation News Service report, said that the San Quentin Six murder and conspiracy indictments were dismissed on January 18, 1974 because the prospective grand-jury pool excluded Black people, Latin Americans, blue-collar workers and young people. This was an intermediate procedural ruling; it is not recorded as an acquittal, a physical release, or the final disposition of the later prosecution.

The Black Panther (February 9, 1974, p. 3), in “San Quentin Prisoners Kept Heavily Drugged,” reported that a writ filed in Marin County Superior Court during the preceding week sought David Johnson’s release from the prison’s maximum-security Adjustment Center. The writ alleged that prisoners were encouraged to take large doses of psychotropic drugs without medical prescriptions or warnings about possible hazards. These are attributed allegations in the reported filing, not established medical findings. The report supplies neither an exact filing day nor a judicial outcome, and release sought from the Adjustment Center does not establish physical discharge from prison.
The September 2025 All of Us or None memorial reports that Johnson died in Texas on June 7, 2025 and was honored at an August 16 memorial. It identifies his nickname G’iap and records George Galvis’s tribute to his Indigenous, Mexican and African roots and his involvement in the community Bike Giveaway. Willie Sundiata Tate recalled Johnson being clubbed unconscious while leaving a courtroom holding cell; this is Tate’s attributed recollection without an exact incident date. Page 7 reproduces a prison letter dated approximately 1972, discussing study, solidarity and earlier life in San Diego. The birth and death dates already recorded are corroborated, not changed.

Contemporary prison-support account and limits
The United Prisoners Union account individually names the San Quentin Six as already imprisoned defendants following the August 21, 1971 events. It describes their first court appearance in October 1971, restraints, conflicts over legal representation, and organizing against prison conditions. These are attributed contemporary descriptions, not an independent finding that every allegation was proved. The account identifies David Johnson and Willie Tate as early signers seeking investigation of Fred Billingslea’s May 1970 treatment. The institutional roster is a custody snapshot only. No hearing, disciplinary-cell move, publication date or later verdict is substituted for this person’s original admission, physical discharge or completed total; existing fields remain unchanged.

Contemporary report of the San Quentin Six disposition
The report says David Johnson was convicted of one assault on a guard, but Judge Henry Broderick suspended his sentence and placed him on three years of probation because of time already served awaiting trial. This corrects the claim that this disposition added a further custodial term. Public defender Frank Cox argued that, without the new prosecution, Johnson would have been freed in 1971; that is an attributed legal argument, not proof of actual discharge in 1971. Neither the probation order nor this clipping establishes the day he physically left custody.
The clipping is by Karen Wald of the Guardian Bureau in San Rafael and is archived under an October 13, 1976 filename. Its printed text says October 1 but does not display the issue year. The report describes sentencing, jury outcomes and defense arguments; it is not a new initial-admission or physical-discharge record. Existing custody endpoints, death fields and served-time totals remain unchanged. Claims of judicial or prosecutorial misconduct remain attributed to the defense and reporter, not independently established findings here.
The original bilingual SanQuentinSix defense pamphlet individually prints David Johnson with historical prison register B16387. Root independently read the original mailing roster in both orientations. This fills the previously blank register only; a historical mailing address does not assert current custody or change any admission, discharge or duration. Pinell’s conflicting printed register is held separately rather than copied over his existing value.
