Day was a cameraman for TVNZ, New Zealand’s leading broadcaster, but changed to building work when he moved to the UK to take a break from the media industry.

His last known location was at his home in Pembroke Street in Clifton, an upmarket suburb of Bristol, on Saturday night, April 30, (BST) when Mulcahy went to London with friends.

It is believed that Day was on a 20-minute walk between his house and a 75-metre-high suspension bridge that crosses Avon Gorge.

Mulcahy had told The Sydney Morning Herald and The Age that she didn’t detect any mental health issues in the days before his disappearance.

“I’ve worked as a Lifelife volunteer for four years and I can pick up when somebody’s unhappy, not themselves and struggling - I really can - and he was honestly the happiest he’s been,” she said.

“My last message to him was reminding him to pull down the blackout blinds because he always forgets and it’s light so long in the UK now.

“His reply was ‘will do’ and then he stopped responding but before that we were talking about how we were going to go to London in three weeks. We just adore each other, we have not had problems in our relationship and I would be truly honest if we did.”

She reported his disappearance on Sunday afternoon (BST) but police did not launch a formal appeal until 24 hours later on Monday.

Within 12 hours they had discovered his body at the bottom of Avon Gorge.

Mulcahy said she knew something was wrong when she arrived home from London about 2pm on Sunday afternoon (BST) and a Hello Fresh grocery box was still outside.
