A man who already has been convicted of murder was supposed to go on trial Thursday for allegedly spitting in the face of an officer at the Leavenworth County Jail.

But the trial of Matthew Astorga was postponed so a new attorney can be appointed to represent him.

Astorga, 40, is charged with battery on a county corrections officer. The crime is alleged to have occurred July 15, 2014.

Court records indicate that the trial was canceled Wednesday because Astorga’s attorney, Joel Rook, is being replaced by a new court-appointed attorney. The next hearing in the case is set for Nov. 1.

Astorga already has been convicted in an unrelated case for the 2008 murder of Ruben Rodriguez in Leavenworth. Astorga is waiting to be re-sentenced in this case.

The sentencing proceeding in that case is scheduled for Nov. 13. Court officials refer to this proceeding as a jury trial because jurors will be asked to determine if Astorga should receive what is known as the Hard 50. This would be a life sentence without the possibility of parole for at least 50 years.
