Walker, in his testimony, said Kepler showed him the business card in the interview room but did not draw attention to what, if anything, was written on the back.

“I handed it (to Walker) with the writing side up,” Kepler told Assistant District Attorney Kevin Gray. However, Kepler said he could not know for sure whether Walker or any other detective at the station read the back of the business card because he didn’t tell them to do so.

The hearing Tuesday covered in detail more than a half-dozen motions filed by the defense since September 2014 ahead of Kepler’s trial, which is set to begin Oct. 3.

O’Carroll asked Holmes whether he could testify in the business card matter because his recollection of Kepler’s interaction with police differed from testimony provided Tuesday by Walker and detective Mark Kennedy. Holmes declined the request but set a “Jackson-Denno hearing” for Sept. 8 to further discuss what Kepler may have told police in his initial interview.

A Jackson-Denno hearing is held to determine whether statements made by a defendant are made voluntarily and following the reading of his or her Miranda rights. At issue are statements made by Kepler indicating whether he had been drinking, as well as a comment he made to police after being told he was arrested for first-degree murder.
