COLUMBIA — Former South Carolina running back Kenny Miles was shot in the arm Monday afternoon during a robbery in the parking lot of a business park in suburban Columbia, authorities said.

Miles was shot in the parking lot on a dead-end street not far from Interstate 26 near Irmo, Richland County Sheriff’s spokesman Curtis Wilson said.

Miles, 23, was in stable condition at a local hospital, Wilson said. The football team’s physician, Dr. Jeffrey Guy, issued a statement later Monday saying that Miles had received a soft-tissue injury from a gunshot wound in his forearm. Guy said Miles was expected to be released from the hospital Tuesday.

Miles was able to give investigators a description of the person who shot him, but no arrests have been made and investigators haven’t determined exactly what Miles and the suspect were doing in the parking lot, Wilson said.

“We’re trying to figure out why he was robbed, but first and foremost, we want to find the person who did this,” Wilson said.

Miles spent most of his career with the Gamecocks backing up Marcus Lattimore. He ran for 1,341 yards on 315 carries.

In his senior season in 2012, Miles ran for 359 yards on 104 carries as he got significant playing time after Lattimore was injured. The best game of his career came when he ran for 127 yards and a touchdown against Wofford. Miles scored two touchdowns in South Carolina’s 2011 Capital One Bowl win over Nebraska.

Miles graduated with a degree in criminal justice.
