Charles “Chuck” Stepanek, 48, pleaded no contest Monday to driving under the influence.

In exchange for his plea, prosecutors dismissed three other counts — willful reckless driving, disturbing the peace and possession of drug paraphernalia — facing the former Legislative District 27 candidate.

A fifth charge, possession of less than 1 ounce of marijuana, previously had been dismissed to pre-trial diversion.

According to court records, police say Stepanek drove under the influence of marijuana in Lincoln on May 29, 2007. Police said he was seen naked at a convenience store near South 27th Street buying a pop, then later at the Sid Dillon car lot, before getting into his car again and driving it into a light pole.

Stepanek had argued he wasn’t under the influence of anything that day; he was experiencing a mental psychosis because of several setbacks.

On Monday, he entered the plea in front of Judge Laurie Yardley. She set his sentencing for Sept. 5.
