Prothro v. State, 302 Ga. 769

In January 2013, Anthony Prothro entered his grandfather Alvin Driver’s home, struck him repeatedly in the head with a 30‑lb dumbbell, took his wallet and debit card, and left; the victim later died from blunt force head trauma.
Prothro returned days later, poured gasoline in the house and on the victim’s body, and set the house on fire; fire and forensic evidence showed the fire was intentionally set and the victim was dead before the fire.
Prothro made voluntary statements to police confessing to the assault, theft, and arson; physical and testimonial evidence linked him to the crimes, including rented movies paid with the victim’s debit card.
A Carroll County grand jury indicted Prothro on multiple counts, and after a bench trial he was convicted of malice murder and other offenses; he received life without parole for malice murder.
On direct appeal Prothro argued ineffective assistance of trial counsel based on counsel’s late filing of a motion for a forensic psychologist and contended such expert testimony would have reduced his conviction to voluntary manslaughter.

Issue	Plaintiff's Argument (Prothro)	Defendant's Argument (State)	Held
Whether counsel’s late filing of a motion for forensic‑psychologist assistance constituted deficient performance and prejudiced the defense	Trial counsel filed the motion on the eve of trial in violation of rules; an earlier timely motion would have secured expert testimony at trial supporting voluntary manslaughter instead of malice murder	The trial court considered the late motion on its merits, denied assistance because sanity/mental state would not be a significant factor, and the proffered expert would not have met legal standards to reduce the offense	Court held Prothro failed Strickland: no reasonable probability of different outcome from earlier filing or proffered testimony; ineffective‑assistance claim denied
