«Investigators say bullets used in the murder of Oakland's school superintendent contained cyanide. Roland Prahl, chief investigator for the Alameda County coroner's office, said Friday that five slugs recovered during the autopsy on the superintendent, Marcus Foster, had the "distinctive odor of cyanide." A coroner's report verified the presence of the poison.»
