Ivan Hernandez v. Michael F. Sheahan, 711 F.3d 816

In 2006, a major jailbreak from the ABO unit prompted an internal investigation of SORT officers guarding ABO detainees.
Darin Gater confessed to helping six inmates escape and named Jones, Rodriguez, Michno, Davis, and Bailey as having aided or foreknowledge.
Gater’s confession, later argued to be coerced, was not suppressed in state court; district court treated it as providing a factual basis for the misconduct alleged.
Officers Hernandez, Rodriguez, Jones, Michno, Bailey, and Davis were investigated and reassigned following the jailbreak and the SORT disbandment.
The Officers asserted several counts including First Amendment retaliation (Counts I-II), conspiracy (Count III), IIED (Count IV), and false imprisonment (Count V).
On remand, the district court denied summary judgment regarding retaliation claims, but the Seventh Circuit reversed on qualified immunity, highlighting that serious jailbreaks can justify vigorous investigations.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether there was probable cause to investigate the Officers	Hernandez claimed lack of reliable, coerced evidence invalidated probable cause	Gater's statement, voluntary per state court, plus others disciplined, supported probable cause	Probable cause established; qualified immunity applies
Whether political association retaliation claims were viable after probable cause	Retaliation for Remus support violated First Amendment rights (Counts I-II)	Investigations were legitimate public-safety actions in light of the jailbreak	No viable constitutional violation given probable cause and immunity defense
