Report: Diminished capacity slaying defense mulled

NORRISTOWN, Pa. (AP) — A defense attorney has indicated that he may use a "diminished capacity" defense in the trial of a teenager accused of having stabbed his girlfriend to death on a suburban Philadelphia hiking trial last year.

Eighteen-year-old Tristan Stahley is charged in Montgomery County in the death of 17-year-old Julie Siller. Prosecutors allege that she was killed in May 2013 after the two along the Skippack Trail, where the two had been arguing.

The (Pottstown) Mercury ( ) reports that court testimony indicates that the proceedings had been delayed by efforts by Stahley's lawyer to obtain an expert witness on diminished capacity.

Defense attorney Timothy Barton indicated to the judge Thursday that a trial date could now be set but didn't reveal if he will move forward with such a defense.
