The evidence is bones that belong to a woman Dorman allegedly killed. Authorities say he carried her remains around in a backpack.
The defense and prosecution spent hours Monday questioning witnesses about the skeletal remains. It's the second hearing in the Dorman case that focused on the remains of Lakeia Boxley.
Dorman's attorney has raised questions about why Boxley's body was cremated and asked if it was an attempt to destroy evidence.
The defense wants the case dropped, saying they should have been given the chance to examine the bones. The state's victim's assistance fund paid for the cremation.
Monday Durham's district attorney called several witnesses to the stand in an attempt to show there was no conspiracy to destroy evidence, but the defense fired off questions to the contrary.
Testimony is expected to resume Tuesday. The judge could make a final decision on whether to dismiss the case.
