That version sounds plausible, and more logical than all the varying night walk stories. Except who would call the police when their partner was only 30 mins late back from their walk, assuming she would normally return after an hour? Surely you'd spend some time ringing friends, likely walking partners and driving around to find her.. If it was my missus I reckon by around midday I would be properly distraught, prior to that I would assume she was distracted or with friends or being vague. Seems early to press the panic button. Guess it depends on how bad her depression was and what was said the night before, to work out whether he should have been beside himself enough to ring so soon, then apparently lose that panic and change his approach as he has with the media/lawyer.
