First of all, sticking to the "we don't know what we don't know" guidelines, there might be witnesses in this case who have not been identified publicly, and sources close to the case have suggested that there are. But among the known witnesses in the case will be Arthur Ting, Bonds' personal physician; Kimberly Bell, Bonds' former girlfriend; and Steve Hoskins, a former friend and business partner of Bonds' who claims to have first-hand knowledge of Bonds' steroid use.
Former BALCO vice president James Valente, who pleaded guilty to his part in the steroid distribution scandal, also is expected to be called. In addition, the government is expected to call several players to testify, including former BALCO clients Jason Giambi, Gary Sheffield and Benito Santiago. At minimum, each player could be asked about his dealings with the lab and what he was told about the substances he took.
