On August 1, 1988, two weeks before the U.S. Olympic diving trials, Kimball, drunk, plowed into a crowd of teenagers while driving an estimated 70 to 90 miles per hour (110 to 140 km/h), killing two boys and injuring four others.[1] Despite the tragedy, Kimball took part in the trials, but failed to make the team.[1] He subsequently pleaded guilty to two counts vehicular manslaughter and was sentenced to seventeen years in prison. He was released on November 24, 1993, after serving less than five years. As a part of his sentence, his driving privileges were revoked by Judge Harry Coe, and were reinstated in 2018.
