Chris Fitzpatrick, 21, of Spencer, has pleaded not guilty to a class A felony charge of first degree murder.
He has also waived his right to a speedy trial.
Fitzpatrick was arraigned Monday, following his filing of a written arraignment and not guilty plea Friday.
Fitzpatrick was initially charged with willful injury, a class C felony, for his alleged role in an early morning beating on Aug. 28. A class B felony charge of first degree robbery was added Aug. 30.
The charge was upgraded to first degree murder, following the death of 59-year-old Edward Kitto on Sept. 8.
Kitto, of Ruthven, was found unresponsive in the 500 block of East Third Street and never regained consciousness, according to Spencer Police Chief Mark Lawson.
Fitzpatrick is scheduled for a Nov. 6 pre-trial conference, with a jury trial to follow on Dec. 11.
He is currently being held in the Clay County Jail on a $250,000 cash or surety bond.
Fitzpatrick was initially represented by J.P. Greer. Gregory Jones, chief public defender of the Office of State Public Defender Sioux City Adult Office, was appointed to the case following the first degree murder charge.
