A man has appeared in court charged with the murder of 17-year-old Jayden Parkinson, who disappeared almost two weeks ago.
Ben Blakeley, 22, of Christchurch Road, Reading, Berkshire, was remanded in custody following a brief hearing at Oxford Magistrates' Court.
Blakeley, who will appear at Oxford Crown Court tomorrow, was charged last night with Jayden's murder and an allegation of perverting the course of justice.
Specialist search teams backed by helicopters and police dogs have been searching for any trace of Jayden, who was last seen leaving Didcot railway station in Oxfordshire on December 3.
A spokeswoman for Thames Valley Police said magistrates have granted officers a further 12 hours to question a 17-year-old boy in connection with the inquiry.
The teenager was arrested on suspicion of murder after attending a police station in Oxfordshire on Friday.
Throughout the weekend, police have continued a detailed search of an area of farmland just outside the village of Upton, near Didcot, where they appeared to be focusing their efforts on an area of woodland near the church.
The police inquiry team has grown to more than 100 officers and a senior officer has said the existing searches may continue for several days.
