Olathe ? Attorneys for the man accused of killing an 18-year-old woman after kidnapping her from a Target store parking lot have again asked prosecutors to hand over electronic data showing how DNA was tested in the case.

Paul D. Cramm, defense attorney for Edwin R. Hall, on Friday filed an opinion written by an expert in the field on why the DNA data is needed. The expert, Dan Krane, an associate professor of biological sciences at Wright State University in Dayton, Ohio, did not return calls seeking comment.

Hall, 26, is accused in the kidnapping, rape and slaying of Kelsey Smith, who was taken June 2 from a Target store parking lot in the Kansas City suburb of Overland Park. A grand jury indicted Hall on charges of capital murder, rape, aggravated kidnapping and aggravated criminal sodomy. The state is seeking the death penalty.

Prosecutors have not said what evidence links Hall to the crime, and a gag order prevents attorneys on both sides from discussing the case.

Prosecutors filed a response to the DNA request Monday, calling the motions “premature or simply moot.” Stephen Maxwell, senior deputy district attorney, said prosecutors soon will provide the defense with an electronic copy of the DNA analyzed by the lab. The data would be in a read-only format.

But Cramm has again requested an unlocked format and says read-only would not be good enough.

Cramm made the initial request for the DNA data to be in an unlocked format at an earlier hearing on evidence in the case.

His argument is that the unlocked format will allow the defense expert the same freedom that prosecutors have to adjust parameters when analyzing the DNA. The issue is expected to be addressed in court today at a hearing.
