According to the New York Daily News, federal investigators have a picture provided by a young man who was at the now infamous Jose Canseco house party in 1998 that reportedly shows definitively that another guest was there: Roger Clemens.
Clemens testified under oath both in a deposition to Congressional staffers and in a hearing before the House Oversight Committee that he did not attend the party, as alleged by his ex-trainer Brian McNamee, who has accused Clemens of taking steroids and HGH. Clemens has denied those allegations repeatedly.
"We have reason to believe it's reliable evidence," Richard Emery, one of McNamee's attorneys, told the Daily News on Thursday. "We believe there's photographic evidence that shows Clemens was at a party he says he wasn't at."
The party was hosted by Canseco for his Toronto Blue Jays teammates and their families at his Miami home during June of 1998, when the Jays were in town for a series agains the Florida Marlins. McNamee has stated that he saw Clemens at the party talking with Canseco, an admitted steroid user, and that some time after the party, Clemens made his first inquiry to McNamee about using steroids.
