IRS special agent testifies in cyclist's perjury trial

SAN FRANCISCO -- The federal government's star witness in the perjury trial of cyclist Tammy Thomas described the genesis of a doping investigation that has reached the highest levels of sports under
questioning by prosecutors.

Internal Revenue Service special agent Jeff Novitzky stopped short of naming names while testifying Thursday. Thomas is accused
of making false statements to a grand jury about steroid use.

Prosecutors directed Novitzky to describe his investigative work without identifying any of the players implicated for steroid use.

Novitzky said he found a trove of evidence in the trash cans of the Bay Area Laboratory Co-Operative, the Burlingame sports lab at the heart of the scandal. The evidence included empty needle wrappers and e-mails.
