The hearing is scheduled to begin Monday in Wilmington before U.S. District Court Judge James Fox. Fox will consider two new types of evidence in the case of Jeffrey MacDonald - a case that terrified the nation and was the basis for the book "Fatal Vision."
The case hinges on testing the DNA of hair found in the home and a deputy U.S. marshal's claim that a prosecutor intimidated a witness during the 1979 trial.
MacDonald is serving three life sentences for the 1970 murders of his pregnant wife, Colette, and their daughters, Kimberley and Kristen.
