FILE - In a file photo of a courtroom sketch, a government informant, identified in court records as Rebecca Williams, testifies Wednesday, Jan. 25, 2012, in Phoenix in the trial of two white supremacist brothers charged with bombing a black city official in Scottsdale, Ariz. Williams, dubbed a "trailer park Mata Hari" by defense attorneys, spent about five years talking with identical twins Dennis and Daniel Mahon, surreptitiously recording their conversations and getting them to open up about the plot with a series of provocative acts. A federal judge is scheduled Tuesday to sentence 61-year-old Dennis Mahon for his conviction in the 2004 bombing. (AP Photo/Maggie Keane/file) less
