Jessica has competed in five Paralympics, winning medals in four of them. Her first games were in Seoul in 1988 where she won silvers in the 100m and 200m and bronzes in the 400m and javelin. By 1992 in Barcelona she was concentrating on the 100m and 200m and managed to convert her two silvers into 2 golds. 1996 Summer Paralympics in Atlanta saw Jessica return to the Javelin as well as the 100m and 200m but she was only able to win a solitary silver in the 100m, competing in the same events in 2000 would result in just the javelin bronze medal. The 2004 Summer Paralympics would be her last games and the only time she did not win a medal after competing in the 100m and Javelin.
