Cobb County investigators say the 29-year-old Oliver was found dead Tuesday night at his home in Marietta, about 20 miles northwest of downtown Atlanta.
Police said Wednesday that Oliver died of a self-inflicted gunshot wound.
Oliver played for the Chargers from 2007-11. His best season was 2010, when he started eight times and had 62 tackles.
Oliver was a 2007 fourth-round supplemental draft pick from the University of Georgia after he was ruled academically ineligible his senior year.
Oliver was released by the New Orleans Saints after training camp in 2011 and returned to San Diego that season.
