Four people paralyzed by botulism were injected with large doses of a raw, unapproved botulinum toxin that someone at their anti-wrinkle treatment clinic bought from a California laboratory, federal documents show. The suspended doctor who administered the shots, Bach McComb, used the material as if it were lower-strength Botox, a derivative of botulinum toxin that is a federally approved medication for wrinkle control and other uses, federal agents said in court papers. McComb and his girlfriend are among the four people who remain hospitalized after getting the shots. Details of the case surfaced in an application for a search warrant filed last week by the U.S. Food & Drug Administration. On Thursday, the agents searched List Biological Laboratories, outside San Jose, Calif.
