Mark D. Sievers v. State of Florida

Summary

The court affirmed Sievers’s convictions for first-degree murder and conspiracy to commit murder and his death sentence. It rejected his guilt-phase challenges, concluding that any evidentiary errors were harmless or nonexistent and that competent, substantial evidence supported both convictions. It also upheld the penalty-phase rulings, including the handling of death-penalty notice, mitigation evidence, the sentencing hearing, and the cold, calculated, and premeditated aggravator.
