The Virginian-Pilot of Norfolk reports that the 27-year-old Summerfield was in a Dare County courtroom on Tuesday. Judge Edgar Barnes read the charge and appointed an attorney.

Summerfield is scheduled to appear in court Sept. 10 for a grand jury hearing.

He's accused of killing Jackenheimer, 33, of Ashland Ohio, who disappeared during a July 4 vacation in Salvo, N.C. with her two children and Summerfield. Her body was later discovered 25 miles from the beach house where they had stayed.

Summerfield returned to Ohio. He left the children with relatives.

U.S. marshals caught Summerfield two weekends ago in a motel room in Medina, Ohio.
