Raleigh, N.C. — Raleigh police investigating the death of a 27-year-old Kinston woman whose dismembered remains were found in Texas this summer appear to be turning to Facebook for clues in the slaying.

In search warrants returned Monday afternoon, detectives asked for permission to obtain all data from the social networking page of Grant Ruffin Hayes, as well as data from a Hotmail account belonging to him. The warrants, however, do not offer any new information in the case.

Hayes, 32, along with his wife, Amanda Perry Hayes, 39, is charged with first-degree murder in the July death of his ex-girlfriend, Laura Jean Ackerson.

Ackerson was reportedly last seen July 13 in Raleigh, where she was dropping off the two children she shares with Grant Hayes. She was reported missing five days later. Her remains were found July 24 in a creek in Richmond, Texas, about 60 miles south of Houston.

Raleigh police haven't commented about the case, but Texas authorities say they believe the Hayeses killed Ackerson, cut up her body and carried it in coolers to Texas, where they disposed of her remains in the creek, which is near the home of Amanda Hayes' sister.

Ackerson's relatives have said she and Grant Hayes had been involved in a contentious child custody dispute over their children. Police, however, have not offered a motive, only referencing the custody dispute in search warrants.
