Nineteen-year-old Bryan Blount is accused of killing 35-year-old Raymond Jackson following an argument last November.
Witnesses told police Jackson criticized Blount for stealing from his own father. The two got into a skirmish.
Prosecutors said that's when Blount threatened to kill Jackson and made good on his promise.
The defense claims Blount did not intend to kill Jackson and fired only in self-defense. But after a 45-minute deliberation, the jury found Blount guilty.
Sentencing will be set at a later date. Blount faces up to life in prison.
For now, he's still being held in the Houston County Jail.
