A Johnson County, Kansas court yesterday sentenced Andrew Ellmaker to life in prison for the murder of his mental health worker, Terri Zenner. He won’t be eligible for parole for 50 years.

The defendant was 17 years old when he killed the victim. Because he was a juvenile at the time of the incident he was not eligible for the death penalty.

Sue Ellmaker, the defendant’s mother, pleaded for mercy because of her son’s mental illness. The victim’s husband, Matt Zenner, would have nothing of it.

“I’m sick and tired of hearing about mental illness,” he said at the sentencing hearing. “Stand up and be a man. You sit there and stare at the floor.... It’s beyond my comprehension that you were able to do this.”

As the husband of the victim, Matt Zenner is entitled to his feelings of loss, anger and bereavement. The family of Terri Zenner deserves all our compassion.

However, as a society we must overcome our prejudice that mental illness is both incomprehensible and inexcusable. Otherwise, we could face even more tragedies like Teri Zenner's.

More than seventy percent of youth in the juvenile justice system suffer from at least one mental health disorder, according to the National Center for Mental Health and Juvenile Justice. For many of their families, juvenile justice provides their first and only access to mental health services.

Families raising a child with mental illness feel frustrated, overwhelmed and exhausted. In my law practice, we help these families by coordinating special education, juvenile justice and mental health services.

Andrew Ellmaker deserves to spend the rest of his life in prison. The rest of us must work even harder to prevent future tragedies from happening.
