STEVENS POINT, WI (WTAQ) - Facing his 11th charge of driving while intoxicated, a Plainfield man is pleading not guilty by reason of mental defect.

A judge ordered a doctor’s examination for 51-year-old Mark Schulke last week.

Conclusions from that exam will be reviewed at a hearing in Stevens Point next month.

Schulke’s first conviction for driving while intoxicated was in 1993. He hadn’t had another one since this 10th conviction in 2004.

Schulke had originally pleaded not guilty, but he asked the Portage County judge to let him change his plea.
