• Grandson charged in Siepmann slaying

Waukesha - A court hearing has been scheduled for Monday to review a new competency report of a teen accused of killing his grandfather in May and to determine whether the homicide case against him can proceed.

Richard B. Wilson, 17, of Fox Point, is charged with first-degree intentional homicide in the May 8 slaying of Ronald Siepmann.

Siepmann, 78, a real estate developer, was found dead in a shed on the property of his Beaver Lake home in the Town of Merton. A bloody ax was nearby.

In June, Wilson was declared incompetent to face charges that he killed his grandfather, and Waukesha County Circuit Judge William J. Domina ordered him committed for mental health treatment.

If Wilson has regained competency, the case against him can proceed.

A report from a court-appointed psychologist who examined Wilson in the aftermath of the killing stated that Wilson has an active psychotic condition, but that he was likely to regain competency with treatment.

A new report was filed Tuesday, but it is sealed.

Wilson's mother told authorities investigating the homicide that Wilson was diagnosed in November with schizophrenia and had stopped taking his medication, according to the criminal complaint filed in the case.
