Michelle Smith has denied tampering with a urine sample given during a random out of competition drug test conducted on January 10 of this year.
At a news conference she read a statement and claimed she was innocent of all charges and that she would fight any charges all the way to the International Sports Court in Switzerland if neccessary.
Prince Alexandre de Merode IOC medical commission chairman reported that the sample submitted by Smith contained deadly levels of alcohol.
Smith's lawyer Peter Lennon has said that the sample must have been tampered with after it was taken from her home.
Smith now has until May 18 to respond to FINA and request that her B sample be tested. The test on the B sample, if conducted may help settle the question of tampering. It is unlikely that the contents of both samples could be altered in exactly the same way, if they were altered after the urine test.
