The father of missing teenager Maureen Braddy is confident she and boyfriend Allan Whyte are still alive.
Stan Braddy told a coronial inquest this morning he was sure because a police officer told him there was "nothing to worry about".
Mr Braddy, 82, is suspected of murdering the two teenagers in 1968.
He told the Coroner's Court this morning that one month after Maureen and Allan's disappearance, police officer Frank Baker called him to tell him the pair were still alive.
"I got a phone call that said not to worry about it, she (Maureen) was in good hands... The voice was of officer Frank Baker," he said.
Mr Braddy also stood by his belief that Maureen and Allan were abducted as part of a 'slavery trade arrangement'.
Facing more than two hours of questioning about his actions on the night of his daughter's disappearance, Mr Braddy said he was "adamant" the teenagers were still alive.
Detective Sergeant Allan Birch told the inquest on Monday Braddy's version of events were "wholly incredible".
