SAN FRANCISCO -- Federal prosecutors urged a judge Tuesday to let them show the jury in Barry Bonds' perjury trial a trove of evidence alleging the slugger mistreated his wife, girlfriends and other people around him.
A court filing submitted by prosecutors included grand jury transcripts and interviews investigators conducted with several witnesses that they plan to call during the trial scheduled to start March 21.
The witnesses include Bonds' former mistress, Kimberly Bell, his personal doctor and a childhood friend who served as his assistant and personal shopper during his playing days.
All three have told investigators that Bonds mistreated his domestic help and his personal trainer Greg Anderson, who is refusing to testify at the former Giant's trial.
Defense lawyers are objecting to their statements as irrelevant to the perjury case.
Bonds' lawyers are also seeking to prevent Bell and Dr. Larry Bower, the medical director of the U.S. Anti-Doping Agency, from testifying about the side effects of steroids. Prosecutors plan to ask Bell about the physical and mental changes such as male pattern baldness and a short, violent temper she said Bonds went through that Bowers will testify are symptoms of steroid use.
Bonds' lawyers own expert counters that those symptoms can be attributed to other causes and that the science of steroid use is still unsettled.
The prosecutors also presented grand jury testimony of Bonds' former personal assistant, Kathy Hoskins. In the filing, Hoskins said she was in a room with Bonds and Anderson and witnessed the trainer inject Bonds with a syringe. Hoskins said Bonds reassured Anderson that it was OK to give him a shot despite Hoskins being in the room.
"Then Greg took out a syringe and he gave him a shot, gave Barry a shot in his naval," Hoskins says in the filing.
One of the five counts against Bonds regards his denial that Anderson ever injected him.
"Need a little something for the road, they can't catch it," Hoskins quoted Bonds as saying of the injection.
The judge will rule on the evidence later.
