State v. Knuff
Annotate this Case
Thomas E. Knuff Jr. was convicted on two counts of aggravated murder with death specifications for killing John Mann and Regina Capobianco. Knuff was released from prison and arranged to stay with Mann. After his release, he began staying at a motel, paid for by a former prison employee, Alicia Stoner, with whom he had a relationship while incarcerated. When his parole officer discovered he was not living at the motel as he claimed, he moved in with Mann. Mann was not living alone; Regina Capobianco also lived there. Knuff and Capobianco had a complicated relationship, and conflict arose between them, which led to the murders.
The Supreme Court of Ohio affirmed Knuff's convictions and the imposition of the death sentences, finding that none of the 24 arguments that he presented justified a reversal. Among other things, the court found that the trial court did not err in denying Knuff’s motion for self-representation, which was made just eight days before jury selection began. The court also rejected Knuff’s claim that the trial court improperly restricted his counsel’s voir dire questioning, thereby denying him a meaningful, constitutionally adequate voir dire. The court additionally found that the trial court did not err in overruling Knuff’s challenges for cause of various jurors, or in granting the prosecution's for-cause challenges.
The court also found that the trial court's error in giving the jury a duty-to-retreat instruction was harmless beyond a reasonable doubt. The court rejected Knuff’s claim that the jury’s finding of guilt for the aggravated-murder counts, felony-murder specifications, and underlying felony offenses was based on insufficient evidence and that his convictions for those offenses were against the manifest weight of the evidence.
