From the WRAL article:
Wednesday's motion also claims that the initial examination performed on the alleged victim did not reach a conclusion as to whether she was raped and that the only trace of physical trauma included a scratch on the alleged victim's knee and heel.
Osborn writes that the alleged victim said she was hit, kicked and strangled, but that the investigator in the case, Benjamin Himan, omitted that "the examining physician … at 3:14 a.m. [on March 14] found no neck, back, chest or abdominal tenderness."
He also writes that the investigator's probable cause affidavit omitted that the sexual assault examination found that "no condoms, fingers or foreign objects were used during the alleged sexual assault."
The motion also states that the nurse who did the examination was not technically certified as a sexual-assault nurse, but that she was still "in training."
But there is a statement that a foreign object WAS used in the hours prior to the Duke "dance appearance" with the couple in the motel/hotel.
