Darin Woods also was convicted of aggravated robbery, attempted aggravated robbery and employment of a firearm in the commission of a dangerous felony.
He will be sentenced May 3 by Criminal Court Judge Paula Skahan.
Woods, 20, was one of three men charged in the incident that occurred around 11 a.m. on April 18, 2014, behind the Ashton Hills Apartments near Raleigh Millington and Egypt Central roads.
The victims were 20-year-old twin brothers who were at a video-game store in the 3800 block of Austin Peay Road when one of the defendants approached them and offered to sell them a video game console.
The brothers agreed and were directed to meet with the seller behind the apartment complex where two other men, later identified as Woods and Rodney Fleming, robbed them of $200.
When they were ordered to get down on the ground, the brothers refused and ran in opposite directions. They said Woods fired several shots, striking one brother in the lower back.
Fleming, 29, pled guilty to attempted first-degree murder, aggravated robbery, attempted aggravated robbery and employing a firearm in the commission of a dangerous felony. He was sentenced to 24 years in prison.
The case against a third defendant, Sanders Malone, 24, is pending.
The case was handled by Asst. Dist. Attys. Sam Winnig and Pamela Fleming Stark.
