Molly Martens and her father Tom are not expected to face a retrial over the death of Irishman Jason Corbett until at least the autumn.
The pair were convicted of second-degree murder in 2015 but successfully appealed and that decision was further upheld by the North Carolina Supreme Court which ordered a retrial.
Davidson County District Attorney Garry Frank said legal teams will meet before a judge in March to determine how far they are from a new hearing date.
