A man has been charged with murdering a 19-year-old woman who disappeared last week, police said.
Jack Wall, 22, from Stevenage, Hertfordshire, was arrested on Sunday by detectives investigating the disappearance of Amelia Arnold.
A body believed to be that of Ms Arnold was found in woodland in Hatfield the same day, four days after she went missing.
A police spokesman said Wall, of Hadrian's Walk, Stevenage, would appear before Hatfield Remand Court on Tuesday.
Formal identification of the body has yet to be carried out, but Miss Arnold's family have been informed and are being supported by specialist officers.
A man arrested on Saturday in connection with the investigation has already appeared in court charged with perverting the course of justice.
Joseph Potter, 41, of Sycamore Avenue, Bletchley, Buckinghamshire, was remanded in custody at Hatfield Remand Court.
