Witnesses have also indicated the possibility of a third gunman,'' he said. Investigators have also ventured onto the Internet, requesting information on more than 50 e-mail accounts from America Online. Authorities have described Anderson, who bought two shotguns and a semi-automatic rifle also used in the massacre, as a cooperative witness. Anderson was 18, old enough to legally buy all three guns, while Harris and Klebold were both 17 when she acquired them. Colorado law does not forbid giving shotguns or rifles to a minor.
Federal law bars such subterfuges.
Anderson could not be reached for comment. The videos may depict the gear and weapons discovered at the school April 20, an official said. A search warrant was executed for records of video games rented April 19. John Heim, owner of Video City Video Superstore on West Jewell Avenue, said he had no idea why authorities are interested in the rental of a half-dozen games by two customers. Doom, a violent video game played by Harris and Klebold, was not among them, Heim said.
