John Mark Karr awaited his first court appearance in Colorado on Monday as a TV station reported that prosecutors decided not to bring charges against him in the slaying of JonBenet Ramsey because his DNA failed to match genetic material on the 6-year-old girl's body.
Denver's KUSA, citing two sources close to the investigation, said that hair and saliva taken from Karr in Boulder after his arrival last week were tested over the weekend at the Denver police crime lab and that he was ruled out as the source of the DNA taken from the crime scene.
Boulder County District Attorney Mary Lacy's office did not immediately return repeated calls from The Associated Press. The Denver police declined comment. Karr's attorneys were with him in jail and were not immediately available for comment.
Karr was scheduled to make his first Colorado court appearance late Monday afternoon.
