Must defendants prove lost evidence would be exculpatory to claim due process violations? State v. Mohamud Explained

The Utah Supreme Court’s decision in State v. Mohamud provides crucial guidance for practitioners handling cases involving lost or destroyed evidence. The court reaffirmed that defendants must meet a specific threshold before claiming due process violations based on missing evidence.

Background and Facts

Khalid Mohamud was incarcerated at Utah State Prison when officers discovered a metal shank in his sock during a routine cell transfer. Defense counsel requested surveillance footage of the incident through discovery, but the State informed defense that any footage would have been automatically recorded over by the time charges were filed 43 days after the incident. Prison surveillance recordings were only preserved for approximately 30 days before being overwritten. Mohamud moved to dismiss the charges, arguing that the lost surveillance footage violated his due process rights.

Key Legal Issues

The case presented two primary issues: whether defense counsel rendered ineffective assistance by stipulating to the legal standard for due process violations involving lost evidence, and whether the lost surveillance footage actually violated Mohamud’s due process rights. Both issues turned on the proper interpretation of the legal standard established in State v. Tiedemann for evaluating due process claims involving destroyed evidence.

Court’s Analysis and Holding

The court held that the Tiedemann standard requires defendants to demonstrate as a threshold matter that there is a reasonable probability that lost or destroyed evidence would have been exculpatory. The court rejected Mohamud’s ineffective assistance claim, finding that counsel acted reasonably by agreeing to the correct legal standard. Regarding the due process claim, the court found that Mohamud failed to meet the threshold requirement because he offered only speculation about what the surveillance footage might have shown, without providing specific testimony about how it would have contradicted the officers’ accounts or aided his defense.

Practice Implications

This decision emphasizes the importance of developing concrete evidence about what missing materials would have shown rather than relying on general assertions about their potential value. The court noted that defendants could meet their burden through witness testimony, their own testimony (without waiving Fifth Amendment rights in certain contexts), or other specific evidence about the content and exculpatory nature of lost materials. Practitioners should prepare detailed proffers explaining exactly how missing evidence would have contradicted prosecution testimony or supported the defense theory.
