OMAHA, Neb. (AP) — A group seeking changes to mandatory minimum sentences in drug cases is pointing to the case of a Nebraska man who will begin a 10-year prison term that even a judge calls “absolutely ridiculous.”

Leo Guthmiller, of Lincoln, will begin his drug conspiracy term Wednesday at a federal prison in Springfield, Missouri.

Federal prosecutors say Guthmiller played a significant role in dealing drugs and pointed to his criminal history. Guthmiller’s public defenders say he simply introduced people looking for drugs to those who were selling and that his history amounted to petty crimes all committed to feed his addiction.

Guthmiller’s supporters note he has been clean since his last arrest in 2013.

The judge who sentenced Guthmiller wants Congress to enact sentencing reforms, calling the mandatory 10-year sentence “absolutely ridiculous.”
