The man accused of intern Chandra Levy's slaying is trying to block an expert from testifying at trial about how she died.
Lawyers representing Ingmar Guandique said in court documents filed Thursday that they object to testimony from a prosecution witness who is expected to say Levy was strangled based on the condition of her bones.
Defense attorneys said they have not been able to independently test Levy's remains because the government turned them over to her family. They argue that it would violate Guandique's constitutional rights to allow testimony on evidence the defense hasn't been able to examine.
Levy disappeared in 2001 and her body was found a year later in Washington's Rock Creek Park.
Guandique has pleaded not guilty to first-degree murder and other counts filed in Levy's death.
