As part of the police investigation into the murder, soldiers residing at Whittington on 7 June were required to complete a form giving an account of their whereabouts for that evening, and providing references. Evans said that he had spent that evening at the barracks, giving the names of three other soldiers who could verify his presence there. However, police subsequently failed to trace one of the named soldiers, and discovered the remaining two had left the barracks prior to 7 June. Evans was questioned again in October by police who visited him at his grandmother's house.
