Biography
Thomas Warner was identified in prisoner-support and political-prisoner listings as a man associated with the Black Panther Party era of U.S. radical politics. He is typically described in those contexts as a political prisoner held in the Pennsylvania prison system, though detailed public documentation of the specific underlying case is comparatively sparse in widely circulated sources.
What is consistently reported in those listings is that he remained incarcerated for years and died by suicide in prison in 1998. Because granular case facts are not broadly available in mainstream summaries, accounts of Warner’s activism and prosecution tend to be presented in brief memorial form rather than as a fully documented public narrative.
Death-date source
Los Angeles Anarchist Black Cross Federation memorial. The account identifies the political prisoner held at Huntingdon, Pennsylvania and reports that he died there on May 25, 1998.
