Melissa Caddick's husband was such an "unimpressive and unreliable witness" he hindered efforts to determine how, when and where she died, a coroner has concluded.
Deputy State Coroner Elizabeth Ryan devoted several pages of her findings on the fate of Sydney fraudster Ms Caddick to critiquing the various accounts given by Anthony Koletti since his wife's disappearance.
The magistrate has a "strong suspicion" Mr Koletti has withheld information about Ms Caddick's movements in the hours before she was reported missing to police.
