Wone judge rules to allow evidence that suggests cover-up

A D.C. Superior Court judge ruled Tuesday that key parts of prosecutors’ case that three housemates covered up the 2006 slaying of Robert Wone can be admitted as evidence.

Judge Lynn Leibovitz said she would admit tests from a forensic expert suggesting that the knife found near Wone’s body was planted. Defense lawyers had said the experiments did not replicate the crime scene.
