On January 23, 2000, Thomas' 1999 Chevrolet Suburban went off Interstate 435 in Clay County as he and two passengers were driving to Kansas City International Airport during a snowstorm for a flight to St. Louis to watch the NFC Championship Game between the St. Louis Rams and the Tampa Bay Buccaneers. Police reports indicated that Thomas, who was driving, was speeding at approximately 70 m.p.h. even though snow and ice were rapidly accumulating on the roadway. Thomas and one of the passengers were not wearing seat belts and both were thrown from the car; the passenger, Michael Tellis, was killed instantly. The second passenger, who was wearing his safety belt, walked away from the scene uninjured. Thomas was left paralyzed from the chest down. By early February, Thomas was being treated at Miami's Jackson Memorial Hospital. The morning of February 8, 2000, while being transferred from his hospital bed to a wheelchair on his way to therapy, Thomas told his mother he was not feeling well. His eyes then rolled back, recalled Frank Eismont, an orthopedic surgeon at Jackson Memorial Hospital. Eismont said Thomas went into cardiorespiratory arrest and died as a result of a pulmonary embolism, a massive blood clot that developed in his legs and traveled to his lungs. Months later, Thomas' family sued General Motors for $73 million in damages stemming from the accident. In 2004, a jury ruled that the family was not entitled to any money.
