Jayden Parkinson graveyard probe reveals recent disturbance
Police searching for missing teenager Jayden Parkinson say they are investigating an "established grave".
The graveyard at All Saints' Church in Lydalls Road, Didcot was searched overnight on Tuesday following a tip-off.
Police said they had found evidence the grave had been recently disturbed.
A semi-detached house in Great Western Drive, a few hundred yards away from the cemetery, has also been sealed off.
A cordon has been put up in a park which links Great Western Drive to an alleyway running behind the cemetery. Forensic officers are examining both areas.
Det Ch Insp Andy Murray of Thames Valley Police said: "We have started securing evidence. We will be here all day and all night if we need to."Forensic investigation
The 17-year-old disappeared on December 3 after she was last seen leaving the town's railway station at about 16:30 GMT.
A blue tent and screening has been erected while forensic officers investigate the grave.
Police said they expected to be at the graveyard for "a number of days".
Jayden's ex-boyfriend Ben Blakeley, 22, of Christchurch Road, Reading, has been charged with her murder.
Mr Blakeley, who has also been charged with perverting the course of justice, is accused of disposing of Jayden's body and lying to police about the last time he saw her.
Police said there have been suggestions Jayden may have been pregnant, but they have been unable to confirm this.
A 17-year-old boy, from Didcot, who has been charged with perverting the course of justice, has also appeared in court and is due back on 17 March.
He is accused of assisting in the disposal of Jayden's body and other evidence.
More than 100 uniformed officers and detectives are working on the case, backed up by specialists from the National Crime Agency.
