HASTINGS, Neb. (AP) — A judge has rejected a Hastings man’s request to withdraw his pleas to charges stemming from the dragging of a police officer.

Thirty-year-old Marty Deckert had accepted a plea deal on charges of attempted second-degree murder and other crimes. But at his sentencing hearing last month, Deckert tried to fire his court-appointed attorney and withdraw his pleas.

Authorities say Deckert tried to avoid arrest in July by speeding away in a car while dragging a police officer.

Deckert said in court on Tuesday that he thought his attorney had pressed him to take the plea deal without fully explaining what it included.

Judge Terri Harder denied Deckert’s motion, saying he didn’t provide enough evidence to back up his argument and had lied at the sentencing hearing.
