Prosecutors have rested their case in the capital murder trial of a Missouri white supremacist who acknowledges killing three people at two Jewish centers in suburban Kansas City.

Jurors on Thursday heard recordings of two phone calls Miller made from the Johnson County jail, in which he admitted killing a 69-year-old man, his 14-year-old grandson and a 53-year-old woman in Overland Park, Kansas, in April 2014.

District Attorney Steve Howe announced afterward that he was finished presenting his case.

Miller asked Judge Thomas Kelly Ryan to postpone the defense part of the case until Monday because he's not prepared. Ryan reminded the 74-year-old he's the one who demanded a speedy trial and fired his attorneys.

Ryan said he would rule on the request after speaking with Miller behind closed doors.
