WICHITA, Kan. (AP) — The district attorney who prosecuted two brothers in a quadruple Wichita homicide is criticizing Gov. Sam Brownback’s use of the case in a new campaign commercial.

Brownback’s ad references Reginald and Jonathan Carr, whose death sentences for the December 2000 killings were vacated in July by the Kansas Supreme Court.

Former Sedgwick County District Attorney Nola Foulston issued a statement Wednesday saying the ad exploits the case for political gain.

Foulston says the ad is a “political last ditch effort” to undercut the qualifications and integrity of the Kansas Supreme Court and Brownback’s Democratic challenger, Paul Davis. She also says it’s disgraceful that the campaign would make the families of the murder victims relive the crime whenever they turn on their televisions.

Brownback’s campaign did not immediately respond to an email seeking comment.
