Tom Sparks was running the first segment of an obstacle course during the October 19 taping of “Wipeout” when he complained of knee pain. On-scene medics immediately sent the former KSKI-FM (103.7) Sun Valley DJ to an area hospital, where his condition steadily worsened following a stroke. The AP reports Sparks was then transferred to Cedars-Sinai Medical Center in Los Angeles and underwent several brain surgeries. It’s believed Sparks died of antiphospholipid antibody syndrome (APS), a rare disease that Sparks never knew he had. He was only 33.
