State v. Diallo

Summary

The Tenth District Court of Appeals of Ohio affirmed the Franklin County Court of Common Pleas’ denial, without a hearing, of Mamadou Aliou Diallo’s postconviction petition. The court held that Diallo failed to provide sufficient operative facts supporting claims that the prosecution knowingly elicited perjured testimony or suppressed or destroyed material Blink camera recordings. The court also concluded that the speculative camera-recording claim was barred by res judicata.

Holdings

1. Diallo was not entitled to a postconviction hearing because his supporting materials did not establish that Chief Schneider's testimony was actually false or that the State knew it was false.
2. Diallo was not entitled to a postconviction hearing because his claim that additional Blink recordings existed and were suppressed or destroyed was speculative and unsupported by sufficient operative facts; the claim was also barred by res judicata to the extent it could have been litigated previously.

Questions Presented

1. Whether Diallo's postconviction materials established substantive grounds for relief and required a hearing on his claim that the State knowingly elicited perjured testimony from Battalion Chief Schneider.
2. Whether Diallo's postconviction materials established substantive grounds for relief and required a hearing on his claims that the State suppressed or destroyed material Blink camera recordings in violation of due process and Brady v. Maryland.

Disposition

affirmed
