An Ohio man charged with killing his on-and-off girlfriend in North Carolina has been indicted on a first-degree murder charge.

The Virginian-Pilot of Norfolk reported that a grand jury indicted 27-year-old Nathan Summerfield in the death of Lynn Jackenheimer of Ashland, Ohio. The 33-year-old mother of two disappeared while she and Summerfield were vacationing in Salvo on Hatteras Island over the July 4th holiday.

Later that month, a medical examiner identified a body found on Hatteras Island as Jackenheimer. An autopsy showed that Jackenheimer was strangled and stabbed.

No hearings have been set for Summerfield.
