John William Kalisz v. State of Florida

Summary

The court affirmed Kalisz's convictions and death sentences after independently reviewing the guilt and penalty phases. It held that Kalisz knowingly, voluntarily, and intelligently waived his Miranda rights, although it found insufficient evidence for two aggravating circumstances; those errors were harmless because four other aggravators supported the sentences. The court also upheld the admission of autopsy photographs and victim-impact statements, rejected the constitutional and cumulative-error claims, found the death sentences proportionate, and concluded that the evidence was sufficient. No separate opinions were filed.
