A year after sprinter Usain Bolt dominated at the London Olympics, a bombshell dropped largely unnoticed in The Gleaner, the Caribbean’s oldest newspaper: A former director of the Jamaica Anti-Doping Commission alleged the island didn’t drug-test athletes for entire months before they dazzled at the 2012 Games.

Statistics compiled by Renee Anne Shirley, former JADCO executive director, indicated a virtual breakdown in the agency’s out-of-competition testing from January 2012 to the July opening of the Olympics.

In an interview with The Associated Press, JADCO chairman Herbert Elliott dismissed Shirley’s figures as lies and described her as “a bit demented.”

But the World Anti-Doping Agency confirmed to AP there was, as Shirley said, “a significant gap of no testing” by JADCO as athletes trained for London — and that WADA would launch an “extraordinary” audit of Jamaican testing.

Track and field’s governing body, the IAAF, reports it extensively tested elite Jamaicans, including Bolt, more than 12 times last year. Bolt, history’s fastest runner, has never failed a drug test. Jamaica won eight of 12 individual sprint medals in London.
