 When staff at the Rainbow told him of Corcoran 's disappearance on 13 November , Smith telephoned the police station at Castle Vale saying that he wished to give a statement . Significantly , his call came at 4 : 00 pm , before the body found in Worcestershire had been positively identified as Corcoran 's , and within an hour Smith had presented himself at Castle Vale . Detective Constable Ruth Wilkins later recalled Smith 's phone call : " He said he would like to come to the police station to help with the inquiry and that he had seen [ Corcoran ] on Saturday night leave the pub with an unknown man . He insisted he would like to come over to the police station . He said he had been asked to contact the police by someone else and gave his mobile number . "
