Thornton v. State, 312 Ga. 224

Victim Jullisa Cooke was found stabbed 55 times on Jan. 10, 2017; she was discovered slumped in her car and her cell phone was missing.
Neighbors saw William Thornton (her ex) outside Cooke’s home that morning in a white Mercedes; one observed him agitated and carrying something.
Police recovered Cooke’s cell phone, a blood-stained gray hooded sweatshirt, gray sweatpants, bloody gloves, a bloodied knife, and paper towels from a trash bag outside Thornton’s residence.
DNA testing matched Cooke to the knife, gloves, and sweatshirt; clothing items matched types associated with Thornton and his employer.
Thornton was convicted of malice murder, armed robbery (taking the phone by use of a knife), and possession of a knife during a felony; he appealed, raising (1) insufficiency of evidence for armed robbery, (2) alleged evidentiary errors (911 call and bloodstain testimony), and (3) denial of a continuance to obtain Facebook records/Brady material.

Issue	Thornton's Argument	State's Argument	Held
Sufficiency of evidence for armed robbery	No direct proof when/how Thornton obtained the phone; other reasonable scenarios exist (e.g., voluntary transfer)	Circumstantial evidence (seen outside agitated, carrying something; phone recovered with bloodied items and Cooke's DNA) permits inference he used/took phone with a knife before or after killing	Affirmed — a rational jury could exclude reasonable alternative hypotheses and convict of armed robbery
Admission of 911 recording and GBI bloodstain testimony	Recording was inflammatory and cumulative; bloodstain testimony was improper expert opinion	Any error was harmless given the cumulative nature of the 911 call and the overwhelming, independent evidence of guilt; bloodstain testimony had little probative/prejudicial effect	Affirmed — even if admission was erroneous, error was harmless beyond a reasonable probability
Denial of continuance to access Cooke's Facebook / alleged Brady claim	Needed continuance to subpoena Facebook for potentially exculpatory/threatening messages from ex-boyfriend Trey; counsel lacked access during trial	Proper process required to obtain account data; defense failed to show diligence, that records existed, or that denial caused prejudice	Affirmed — trial court did not abuse discretion; defendant failed to show diligence or harm; no Brady violation shown
