Court documents show that a man accused of killing three women in Utah so he could steal their cars and credit cards was already known to police in Iowa. Twenty-two-year-old Ivan Miller had been due in court on Friday in Iowa, where he is accused of breaking into a cabin and illegally hunting in a game refuge back in December. Miller had been released without bail on those charges. He is now jailed in Colorado on suspicion of the three killings in neighboring Utah on Wednesday. Miller has no attorney on file in Colorado, and his Iowa attorney did not immediately return a call seeking comment.
