The Wake County District Attorney will ask a judge to keep secret for another month search warrants used to investigate the homicide of Nancy Cooper of Cary.

Cooper, a 34-year-old mother of two, was killed last month. Her body was found in an unfinished subdivision near her home in Cary’s Lochmere subdivision.

Police have not named or captured her killer.

Cary police have searched her family’s home, two cars and her husband’s office in Research Triangle Park. They have also collected blood or saliva from her husband, Bradley Cooper, to help obtain his DNA profile.

Explanations for the searches and an inventory of what was collected have been sealed since police began investigating. Search warrants are typically made public after police complete their inventory.

The initial order to seal, signed by Wake County Superior Court Judge Donald Stephens, was set to lapse Saturday.

In a motion filed late Friday, Amy Fitzhugh, Wake County Assistant District Attorney, said she will ask for another 30-day seal on the warrants, saying that their release could impact a possible defendant’s right to a fair trial.

Stephens is scheduled to hear the request Monday afternoon.

Attorneys for The News & Observer and WRAL have asked Stephens to make the warrants public and will ask the judge to refuse any additional orders to keep them sealed.
