Dickerson v. Mississippi
Annotate this CaseDavid Dickerson was convicted by jury of killing his ex-girlfriend and mother of his daughter by shooting and then burning her. In 2015, the Mississippi Supreme Court affirmed Dickerson’s capital-murder conviction and sentence of death, along with related convictions and sentences for arson and armed robbery. Dickerson petitioned for post-conviction relief, arguing he was “he is intellectually disabled as defined by the Court in [Atkins] and thus he is ineligible for the death penalty.” Specifically, Dickerson insists that the PCR “and its accompanying affidavits[] contai[n] much evidence that” he “meets all three criteria for mental retardation”—“subaverage intellectual functioning[,]” “significant deficits in adaptive functioning[,]” and that the “deficits manifested before age 18.” The Supreme Court again declined post-conviction relief, finding that Dickerson’s PCR claims were barred and/or failed to present a substantial showing of the denial of a state or federal right.
