Walter Logan, 52, allegedly bound and gagged the victim, 29-year-old Alex Shipp, following a fight.
Logan has told investigators he then fell asleep, and woke up to find Shipp dead on the ground with blood around his head. He said he shoved Shipp's body into an unplugged freezer in his basement, where police found his decomposing remains.
Kokomo, Ind., police said they were investigating Shipp's missing person case when they found out Logan had admitted to a third party he killed Shipp.
Howard County prosecutors added three additional counts to Logan's indictment -- murder while attempting deviate conduct, reckless homicide and confinement, the Kokomo (Ind.) Tribune said.
Howard County Circuit Court Judge Lynn Murray granted Logan's lawyer a continuance. Jury selection had been scheduled Wednesday but the trial has now been put off until Oct. 7.
