May's reliance upon Arizona v. Youngblood, 488 U.S. 51 (1988), for the legal principle that when
lost, destroyed, or unavailable evidence is merely potentially useful rather than apparently
exculpatory, a defendant must demonstrate bad faith by law enforcement to establish a due
process violation. Youngblood is cited to establish that the failure to preserve potentially useful
evidence does not constitute a denial of due process absent a showing of bad faith. May relies
upon this authority to support his claim that law enforcement agencies involved in his case failed
to properly preserve, maintain, account for, or disclose physical evidence and that publicly
documented evidence-management failures by APD and BCSD support further inquiry into
whether those failures resulted from bad-faith conduct.
