Karr case falls apart

8226; DNA tests were conducted by the Denver Crime Laboratory on August 25 on a cheek swab taken from Karr. Boulder District Attorney Mary Lacy said on Tuesday that the test results did not put Karr at the crime scene.

8226; Karr emerged as a suspect in the 10-year case in April after exchanging emails with a University of Colorado journalism professor, Michael Tracey, in which he said he had accidently killed JonBenet during sex.

8226; Prosecutors suggested in court papers that Karr was a just a man with twisted obsession who confessed to a crime he did not commit. He still faces charges for child pornography dating to 2001.

8226; JonBenet, daughter of wealthy entrepreneur John Bennet Ramsey, was six years old at the time of her death.

She had won a number of beauty pageants. She was found strangled to death in the basement of her Boulder home on December 26, 1996. Evidence suggested she had been sexually assaulted.
