Throughout today there has been a large police presence at the church, with forensic teams unloading equipment from vehicles and carrying it into the cemetery where a meticulous and careful search has been carried out.
The teenager, who had recently moved to Oxford, was last seen leaving Didcot railway station at 4.27pm on the day of her disappearance. Officers had previously appealed for information about a man seen struggling with a suitcase just outside the village of Upton, at about 2am on Monday December 9.
Police investigating the disappearance of Jayden Parkinson have said there is evidence of a "recent and unauthorised disturbance" at a grave site in All Saints' Church in Didcot, Oxfordshire.
Detective Chief Superintendent Andrew Murray said forensic scientists had begun the "difficult process" of securing evidence at the grave site, in a cemetery close to where Jayden was last seen in Didcot.
He said the family of the person the grave belongs to has been informed.
Detectives are in constant contact with Jayden's family as the examination of the grave, which could take a number of days, progresses.
