Biography
Hugo "Yogi Bear" Pinell was a Nicaraguan-born prisoner and member of the San Quentin Six. Already imprisoned before the August 21, 1971 San Quentin events, he was later convicted of aggravated assault. He spent decades in solitary confinement. He was killed in custody at California State Prison-Sacramento (New Folsom) on August 12, 2015; this was not a release or parole. Earlier text describing him as awaiting future parole is obsolete.
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.

Defenestrator reported that Hugo Pinell remained in Pelican Bay’s Security Housing Unit and that a January 2009 decision denied him parole for fifteen years. The denial is a prospective review interval, not fifteen years already served or an actual release date. Defenestrator, issue 44, April 2009, original PDF page 14.

The Militant report, spelling the name Hugo Pinnel, says Marin County Superior Judge Joseph G. Wilson refused to halt grand-jury hearings directed at Pinell, Larry Spain and attorney Steven Bingham concerning the August21,1971 San Quentin events. These were investigatory proceedings, not completed verdicts, new custody admissions or releases.

The Black Panther reports defense attorney Charles Garry’s examination of guard testimony about the August 21, 1971 San Quentin events. Its allegation that officials planned Jackson’s death is attributed to the defense account; this trial reporting is not a new conviction or release.

2010s audit verified October 12, 2026: The original August 2015 prison-movement report, retained and read locally, reports Pinell killed in the prison yard August 12, 2015 at New Folsom. Both records incorrectly encoded his death as release; those release endpoints were removed, death-in-custody recorded in both, and the stale released status corrected. The two overlapping records do not establish two separately served intervals. Unsupported totals were cleared; no replacement initial admission date is guessed.
Audit follow-up October 13, 2026: The previously verified death-in-custody report remains the source for August 12, 2015. The nightly update had incorrectly restored that death as a release in both overlapping cases. Those release fields are cleared again, now protected by the approved calculation fix that keeps death and release distinct. The unsupported August 20, 1971 admission was also cleared: Pinell was already imprisoned before the San Quentin events, and that event date does not establish his initial entry into custody. No replacement admission date or continuous duration is guessed.
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 author alleges that Pinell was placed in a quiet cell beginning March 16 and subjected to repeated beatings; no year is printed beside that date, and it is a segregation claim, not a first prison admission. 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 Hugo Pinell received two concurrent life terms at the October 1 sentencing after assault convictions involving two guards. It names Judd Scott as assisting Pinell in representing himself and describes immediate appeals. The described nine-year parole eligibility is not an actual parole or release date.
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.
In November 1971 the Black Panther Party formally announced Pinell as a member in good standing. Its account emphasized his cooperation with George Jackson against racial divisions among prisoners. It also described separate allegations of assaults at San Quentin and Soledad before the San Quentin Six prosecution, including a December 14, 1970 accusation at Soledad. These allegations and prison transfers are distinguished from his underlying 1965 conviction and do not establish new admission or release dates.

In a letter dated March 31, 1987, published in Workers Vanguard, Pinell describes his 1976 transfer from San Quentin to Folsom and says he was then at Tehachapi. He reports a 1986 parole denial for three more years and more than sixteen years without a contact visit. These are his attributed descriptions of institutional treatment during existing imprisonment, not a new admission, an actual parole date or a separate served-time total.
