On July 6, double-amputee Olympian Oscar Pistorius, was sentenced to six years in prison for murder. The South African, who competed in the 400-meter sprint at the 2012 London Olympics, was convicted for firing four bullets into his bathroom door, killing his girlfriend Reena Steenkamp on Valentine’s Day three years ago.

In this high-profile long-running set of trials, Pistorius claimed someone had intruded his home and that he fired his gun fearful for his life. Many feel that Pistorius was let off easy, his six years not coming close to what many thought would be a 10- to 15-year sentence.

In the long history of the Olympics, Pistorius joins a small group of Olympians who served time for murder, according to one my favorite go-to books, The Book of Olympic Lists, by David Wallechinsky and Jaime Loucky. In their list of 20 Olympians Who Did Time in Prison, there are four other Olympians who went to the slammer for murder.

James Snook: Snook was a member of the gold medal winning US Free Pistol Shooting team at the Antwerp Games in 1920. At the age of 48, then a professor of veterinary medicine at Ohio State, Snook confessed to the murder of his mistress, Theora Hix. He was put to death in the electric chair after being found guilty of taking a hammer to Hix after violent sex at a rifle range.

Humberto Mariles: This two-time gold medalist and bronze medalist equestrian from Mexico competed at the 1948 Games in London and the 1952 Games in Helsinki. One August summer day, Mariles experienced an extreme fit of road rage when another motorist forced him off the road. According to Wallenchinsky and Loucky, “at the next traffi light Mariles pulled out a gun and shot the man.” Mariles was sent to prison but was pardoned by the President of Mexico.

Ludovit Plachetka: Plachetka was a middleweight boxer from the Czech Republic who won his first match at the 1996 Atlanta Olympics against a boxer from Swaziland before being eliminated by a boxer from Uzbekistan. According to Wallechinsky and Loucky, Plachetka went from Olympian to felon in less than a year. Apparently he was in an ongoing dispute with his girlfriend over visitation rights of their child that escalated to the point where Plachetka shot to death the mother of his girlfriend. He would have shot his girlfriend if not for gun jamming at that moment. The former boxer/bouncer was sentenced to 13 years.

As for Pistorius, six years may seem like a long time for him. But a top sports officials in South Africa has said the sentence includes time served, and that with good behavior could be out in time to train and participate in the 2020 Tokyo Paralympic Games.

According to the Daily Mail, “Tubby Reddy, CEO of South Africa’s Sports Confederation and Olympic Committee, said he had ‘no problem’ with the idea of the ‘Blade Runner’ returning to the national team and representing his country at the highest level – despite widespread condemnation of Pistorius’ crime and six year sentence.”
