WASHINGTON – The man accused of killing federal intern Chandra Levy in Washington in 2001 has pleaded not guilty to charges he threatened a witness in the case.
Ingmar Guandique was indicted this month on counts including obstructing justice after authorities said he conveyed the threats from jail.

Guandique's lawyer entered a not-guilty plea for him to the new charges during an arraignment Tuesday in D.C. Superior Court.
Guandique has already pleaded not guilty to first-degree murder and other counts filed in April over Levy's death.
Levy vanished in 2001 after completing an internship with the U.S. Bureau of Prisons. Her body was found a year later in Rock Creek Park.
Guandique has been serving a 10-year sentence for separate assaults in Rock Creek Park.
