A Raleigh couple was ordered held without bond Tuesday in the death of a Kinston woman whose remains are believed to have been found in a south Texas creek.

District Judge Jacqueline Brewer appointed public defenders for Grant Ruffin Hayes, 32, and Amanda Perry Hayes, 39, and set their next court date on Aug. 16.

Laura Jean Ackerson, 27, a businesswoman and mother of two, was last seen July 13, and her business partner reported her missing five days later.

A dive team for the Fort Bend County Sheriff's Office in Richmond, Texas, found some remains scattered in a creek about 60 miles south of Houston late Sunday. The search for remains continued on Monday and Tuesday.

Investigators said they believe the remains are those of Ackerson and that she was killed in North Carolina before her killers hauled her dismembered body in coolers to Texas for disposal.

Amanda Hayes' sister lives across the street from a wooded area that includes Oyster Creek, and Texas authorities said that Grant and Amanda Hayes arrived in Richmond last Monday.

Investigators took a machete from the house, but it was unclear whether it is related to the case. Detectives also seized several ice chests.

Raleigh police also have not commented on a possible motive for Ackerson's death, but family members and friends have said that Ackerson and Grant Hayes were involved in a custody battle over their two young sons and that their relationship had been "volatile."

Ackerson's car was found at a north Raleigh apartment complex on July 20. The complex is less than a quarter-mile from the Woodfield Glen Apartments complex where the Hayeses live.
