Emanuel Johnson v. State of Florida

Summary

The court affirmed the denial of postconviction relief from Johnson's conviction and death sentence for Jackie McCahon's murder. It held that Johnson failed to establish prejudice from counsel's failure to authenticate medical records because the relevant mitigation evidence was otherwise presented and additional evidence could have opened the door to harmful testimony. The court also held that challenges to the separate conviction used as a prior-violent-felony aggravator did not undermine the sentence because that conviction remained valid.
