The seventh-circuit reversed the district court’s denial of summary judgment, holding that the police officers and private polygrapher are entitled to qualified immunity on the plaintiff’s claims for unlawful detention, coerced confession, and destruction of evidence, and are entitled to absolute immunity regarding the fabrication of evidence claim. Regarding the Fourth Amendment unlawful detention claim, the court applied the “arguable probable cause” standard, determining that officers are protected if a reasonable officer could have believed probable cause existed based on the totality of circumstances. The court found that undisputed facts—including the discovery of a nightstick at the crime scene, witness testimony placing the plaintiff with the weapon, and reports from a news reporter and foster mother linking the plaintiff to the murders—provided arguable probable cause for the detention, thereby barring liability. On the Fourteenth Amendment claim regarding the destruction of evidence, the court applied the standard requiring proof that officers acted in bad faith and that the evidence had apparent exculpatory value at the time of destruction. The court ruled that the plaintiff failed to provide specific facts showing when the evidence was destroyed or that it was destroyed in bad faith. Furthermore, the court found that no clearly established law existed prior to 1984 (the date of *California v. Trombetta*) imposing a duty on officers to preserve such evidence for potential future DNA testing, as officers could not reasonably be expected to anticipate scientific advances decades later. Regarding the Fifth Amendment coerced confession claim, the court applied the “clearly established law” standard to determine if the officers’ interrogation tactics were obviously unconstitutional at the time they occurred in 1977. The court concluded that while the plaintiff’s treatment was not textbook by modern standards, it was not so egregious that no reasonable officer could have believed the conduct was lawful. The court distinguished the plaintiff’s case from controlling precedents like *Haley v. Ohio* and *Gallegos v. Colorado*, noting that the plaintiff received Miranda warnings, met with his father and probation officer, and confessed after a shorter duration than the minors in those cases. Consequently, the officers were not on notice that their specific conduct was beyond a doubt illegal. Finally, regarding the claim that officers fabricated evidence and testified to it, the court held that individuals are entitled to absolute immunity for trial testimony under *Briscoe v. LaHue*. The court reasoned that because the allegedly fabricated police reports were never introduced or used as evidence at the plaintiff’s criminal trials, they did not violate his right to a fair trial. Even if the officers’ testimony was consistent with fabricated reports, such testimony is protected by absolute immunity, and the plaintiff could not establish liability based on the reports alone since they were not admitted into evidence. The practical consequence of this ruling is that the civil rights lawsuit against the officers and polygrapher for these specific claims is dismissed at the summary judgment stage, preventing the case from proceeding to trial. The plaintiff’s appeal regarding these immunity defenses was resolved in favor of the defendants, effectively ending their liability exposure for the alleged constitutional violations described.
