MADISON, Wis. (AP) — A judge in Dane County has arranged a competency examination for the man charged with murdering a University of Wisconsin-Madison pupil in 2008.

Lawyers for David Kahl state he’s had recent clinical episodes that raise questions regarding whether he has the capability to aid in his defense. The character of these episodes weren’t clarified in the defense lawyers’ letter to Judge Juan Colas.

The 54-year-old suspect was charged annually with first-degree intentional homicide in the death of 21-year-old Brittany Zimmermann. Prosecutors state Kahl stabbed and strangled Zimmermann after visiting homes in her area requesting cash.

Colas on Monday ordered Kahl to possess a proficiency test with a report completed within 15 days when Kahl has been given an inpatient examination or 30 days when it is in an inpatient facility.

Kahl is scheduled for a preliminary hearing prior to Colas on March 25.
