State v. Ferguson, 54 So. 3d 152

Defendant Barry Ferguson was convicted of first-degree murder for the May 23, 2003 killing of his sixteen-year-old daughter Brandy Ferguson and was sentenced to life imprisonment without parole.
He was found competent to stand trial after lunacy/competency proceedings conducted in 2004.
The State filed multiple suppression and discovery motions; the trial court denied suppression motions and the court heard related evidentiary testimony through 2008.
Trial proceeded from March to April 2009 with a death-qualified jury; the jury found Ferguson guilty as charged and recommended life imprisonment without parole.
Key evidentiary issues included the handling and testing of clothing (underwear, t-shirt, jeans) seized at Central Lockup and later subjected to serology/DNA analysis, and whether the state’s evidence procedures preserved opportunities for independent testing.
The court affirmed Ferguson’s conviction and sentence, rejecting the assigned errors regarding expert qualification and testing and chain-of-custody concerns.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether Tafaro qualifies as a serology expert	Ferguson argues Tafaro is not an qualified serology expert.	State contends Tafaro is qualified by experience and prior qualifications.	Tafaro qualified; no abuse of discretion.
Whether Ferguson was denied right to independent testing and whether chain of custody affected DNA admissibility	Right to independent testing was denied; potential prejudice to defense.	State preserved evidence and independent testing was not essential; testing credible.	No reversible prejudice; chain of custody sufficient for adducing DNA evidence.
