TOM Meagher knew Adrian Bayley had ''done something'' to his then missing wife, Jill Meagher, when he saw video footage of him on the night she disappeared.
Mr Meagher told The Late Late Show on Friday night on RTE 1 in Ireland that he feared the worst on the night his wife, 29, went missing. On September 22, 2012, Adrian Ernest Bayley raped and murdered Jill Meagher.
Mr Meagher said police had invited him to watch closed-circuit television footage showing Bayley but he instead watched it on the news.
''We just watched it on television," Mr Meagher said. "It was just numbing – it was so chilling. I can't actually unpack the emotions.
“I knew as soon as I saw that man standing in the doorway he’d done something to her,” he said.
“Jill hasn’t been home since Friday night and there’s this man lurking in a shop hallway. The fact you can see almost her last moments – it's horrifying.”
Mr Meagher described his panic and frantic search after she failed to return home from a night out with ABC work colleagues. He walked the streets of Brunswick in the early hours of that Saturday and had been comforted that her phone continued to ring.
''It reassured me that it kept ringing. And it was only when it rang out that it went straight to voicemail ... I was panicking the whole time but when it went to voicemail it was blind panic.
''I went looking for her which was really a strange thing to do because the streets are completely empty," he said. "There is no one on the street, it is really eerie.''
He described calling police as ''confronting''.
“You have to say the words ‘my wife is missing’. Just to say those words really just guts you,” he said.
He said when police had Bayley in custody he was still clinging to hope that she was alive.
“I was clutching at straws, I was saying is there any chance she’s still alive? Is there any chance she could be kept somewhere? I was just clutching at anything at that stage. And they were saying ‘look, don’t get your hopes up’.”
Ms Meagher's body was found dumped at Gisbourne South, north-west of Melbourne.
Bayley was convicted of her rape and murder and sentenced to 35 years' jail.
At the time Bayley murdered Ms Meagher, he was on parole after serving eight years for the rape of five women in 2002. While on parole he assaulted a man in Geelong.
Mr Meagher said he read the 2002 rape court documents to understand the parole system.
''When I read those documents I literally vomited," he said. "It was so disgusting. I mean, so brutal. I don't know how anyone can read those documents and let this man back on the streets, ever.''
He questioned the Victorian parole board about its processes for releasing such a violent criminal. He said the board admitted it was ''at fault for not cancelling the parole''.
Mr Meagher, who has returned to Ireland to live, is the face of The White Ribbon Campaign, a male-led movement trying to change attitudes and behaviours that lead to attacks on women. He initially worried the role might ''trigger'' his grief but said it had helped him.
On April 17, Mr Meagher wrote a piece on White Ribbon's website about his experience during Bayley's trial for his wife's murder.
''I hated him [Bayley] obviously and I still do," Mr Meagher said. "I would have to have some sort of religious experience to get to a point where I don't.
''At first I had lots of thoughts of revenge. Lots of violent thoughts, but I came to a point that I realised how destructive that was. That didn't happen overnight.
''With the campaign I am challenging that into a much more productive thing,'' he said.
