Talley is set to be sentenced Oct. 12 and was taken to jail after the verdict.
According to the evidence presented in court, Talley and Gann met the night preceding Gann's death, which was caused by a gunshot wound the chest. The .22 Magnum round, fired by Talley who had her boyfriend's rifle at an Acworth party, killed Gann almost instantly. His heart was perforated several times.
The jury found Talley was criminally negligent and either intoxicated or reckless with the firearm or both. Talley's attorney argued the shooting was an accident and that Talley, who said she carried the rifle for protection from a man who allegedly threatened her sister, was not intoxicated, although evidence indicated she had been drinking.
Talley did not take the stand during trial but said in a police interview she tried to fire the gun in a different direction, but it went off and hit Gann. The two had been discussing the firearm, and witnesses said Gann, who thought it was a BB gun, issued a challenge to fire the weapon, which is designed for small game hunting.
