In a civil rights case against a Louisiana city and various others brought by plaintiff who was incarcerated for twenty years before DNA testing proved him innocent, denial of defendant-laboratory technician's motion to dismiss on the grounds of qualified immunity is affirmed in part where: 1) the deliberate or knowing creation of a misleading and scientifically inaccurate serology report amounts to a violation of a defendant's due process rights, and a reasonable laboratory technician in 1984 would have understood that those actions violated those rights; and 2) denial of qualified immunity was also proper on a claim that defendant concealed, suppressed, or destroyed lab results that were conclusively exculpatory with respect to plaintiff.
