Dustin McCowan pleaded not guilty to murder charges. An autopsy revealed Bach died from a gunshot wound to the neck. Her body was found Saturday along railroad tracks near McCowan's home.
One of McCowan's neighbor's told police she heard voices outside her home the night Bach was last seen saying, "Amanda get up."
"You can see it in his eyes, there's, he's scared and there's guilt. And it's horrible, horrible, it's a horrible thing. We all don't know how to stomach it right now," said Tara Adams, one of McCowan's friends.
Service for Bach will be held later this week.
