Biography
Denis Leyne was one of the Tucson Six, defendants prosecuted over alleged arms supplies to the IRA. He was held in US federal custody before the six were acquitted in April 1994.
The official federal locator identifies Denis Joseph Leyne, register 27953-054, and reports actual release April 1, 1993. The distinctive name, age and adjacent register series match the Tucson Six detention. This supplies the missing endpoint for the existing November 11, 1992 custody start. Bail authorization and later acquittal are not treated as physical release.
