Meryl S. McDonald v. State of Florida

Summary

The court affirmed the summary denial of McDonald’s fourth postconviction motion, rejecting both his prosecutorial-misconduct claim and his newly discovered evidence claim based on a later federal letter criticizing FBI hair-analysis testimony. The court held that the prosecutor could not have corrected allegedly false testimony using information issued nearly twenty years after trial and that, even considering the letter, the evidence would not probably produce an acquittal on retrial.
