In this 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. 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.

PHOENIX — An attorney for one of two white supremacist brothers charged in Arizona with bombing a black city official in Scottsdale is trying to paint a government informant as a temptress who led one of the brothers to believe that she would have sex with him so he would admit to the crime.

Attorney Deborah Williams on Thursday played for jurors numerous tapes of the informant flirting with identical twin brothers Dennis and Daniel Mahon and talking about sex.

Williams is trying to undercut the credibility of the 41-year-old informant, a former exotic dancer.

The Mahons, both 61, have pleaded not guilty to the 2004 bombing of Don Logan, Scottsdale's diversity director at the time. His hand and arm were injured, and a secretary also was hurt.
