The son of National Association of Stock Car Auto Racing engine builder Ernie Elliott and nephew of 1988 Winston Cup Series champion Bill Elliott, Casey Elliott grew up among racers and racing, and, taking up the sport as a career in his teens, quickly proved adept at competition, racing at Lanier Raceway and other tracks in Georgia.
He qualified in the top ten for both events, finishing 20th in his debut at Michigan International Speedway. In October at Charlotte Motor Speedway he started fourth, outqualifying his more famous uncle, but finished 44th following an accident. Elliott planned to compete full-time in the Busch Series starting in 1994.
However, in December of 1993, a medical examination revealed that a growth on his upper right thigh was cancerous.
He had surgery to remove it in February 1994. Although it was believed that the cancer had been confined to the removed tumor, and Elliott initially showed improvement, the cancer had already metastasized.
Not long afterwards Elliott required knee replacement surgery, ending his racing career. Elliott stated his intention to take up a career as a minister with Motor Racing Outreach.
Over the next two years he underwent treatment, however in late 1995 his condition deteriorated.
In January 1996, he died of the disease. Jerry Glanville, coach of the Atlanta Falcons and a part-time National Association of Stock Car Auto Racing competitor whom Elliott had been scheduled to crew chief for during the 1996 season, described Elliott as "a super, super kid". Lanier National Speedway established the annual Casey Elliott Memorial Race in his honor.
The nephew of 1988 National Association of Stock Car Auto Racing Winston Cup champion Bill Elliott, he raced in the National Association of Stock Car Auto Racing Slim Jim All Pro Series and Busch Series before being diagnosed with cancer. He turned to the motorsports ministry and crew chiefing before his death from the disease at age 21.
