McNamee will investigate Clemens

In an ongoing saga with almost weekly twists, former trainer Brian McNamee is prepared to have Roger Clemens investigated by retired New York City police officers, according to a report yesterday in the New York Times. Richard Emery, one of McNamee's lawyers, said two investigators were already working on McNamee's behalf and would go to Houston if a motion to dismiss a defamation lawsuit filed by Clemens last January is denied. Clemens will not be interviewed, according to the Times, but investigators will attempt to find out information about him, including a possible connection to steroids and human growth hormone.
