Dustin McCowan is accused of killing 19-year old Amanda Bach of Portage.
He was scheduled to go on trial January 30th, but now a judge has pushed it back to August.
Bach disappeared one evening in September. Searchers found her body two days later.
She died from a bullet wound to the neck.
McCowan reportedly told police that Bach had been at his house earlier in the evening but that he did not know what happened to her after she left.
