Officers had previously issued an appeal for information about a man seen struggling with a suitcase just outside the village of Upton, at about 2am on Monday, December 9th. A painstaking search of farmland on the outskirts of the village had been continuing, following reports of that sighting.
Officers said the same man was later seen with the same suitcase in the Lydalls Road area of Didcot - where All Saints is located - at about 3.30am the same day. Detectives have since recovered several suitcases, one of which "may well be significant", according to Mr Murray.
Police also confirmed that during the course of their investigation it had been suggested Jayden may have been pregnant at the time of her disappearance, although Mr Murray had previously said they "had no way of confirming whether this is correct or not".
