Mammone v. Jenkins, No. 20-3069 (6th Cir. 2022)
Annotate this Case
In 2010, a jury convicted Mammone of the aggravated murder of his two children and his former mother-in-law, aggravated burglary, violation of a protective order, and attempted arson. Mammone’s mother, his father, and a psychologist testified on his behalf at sentencing, and Mammone gave a five-hour unsworn statement. The jury recommended and the court imposed three death sentences plus 27 years of consecutive imprisonment for his noncapital offenses. The Ohio Supreme Court affirmed.
The Sixth Circuit affirmed the denial of his habeas corpus petition, 28 U.S.C. 2254. The court rejected Mammone’s arguments that pretrial publicity was so prejudicial that he did not receive a fair trial; that the jurors unconstitutionally prayed before penalty-phase deliberations; and that trial counsel and appellate counsel were ineffective. The Ohio Supreme Court held that it could not conclude that pretrial publicity rendered Mammone’s trial a “hollow formality.” That decision was not an objectively unreasonable application of Supreme Court precedent. Mammone cites no Supreme Court precedent holding that prayer by jurors amounts to the influence of extraneous information. Mammone’s underlying claim that trial counsel should have pursued a defense of not guilty by reason of insanity is not substantial because he cannot overcome the presumption that the decision was strategic.
