ANTIOCH, Tenn. (WRKN) — A second arrest has been made in a shooting investigation from earlier this month.

On Wednesday, detectives arrested 18-year-old Avion Oldham. He is accused to be the second car burglar and gunman who opened fire on a Shoemaker Court resident on May 14.

Oldham was arrested by undercover detectives Wednesday as he sat in a car in the parking lot of a Tulip Grove Road apartment complex.

Detectives found a pistol and bullets matching the caliber of those found on Shoemaker Court in Oldham’s car. Officers also found 189 grams of marijuana and eight oxycodone pills.
