Tonight on Sunday ` when a Kiwi family turned detective. There was a note, a cut wrist and pills. Was it suicide or was it murder? 'He looked at me as though he was going to kill me. Oh my God!' The victim's family turns cop. Scrawled in the top corner were the words, 'He did it.' We have just had a big fire in the Rovers. Secrets from the street. Someone dies. Ken Barlow on his life and loves. ... but that doesn't mean he's a great wonderful lover and lothario. Copyright TVNZ Access Services 2013 'He did it' ` words from beyond the grave found in a note by the body of a NZ mother. The message was apparently missed by New South Wales police. They insisted Nadine Haag had committed suicide, but Nadine's Kiwi family reckoned the cops had jumped to the wrong conclusion, and they opened their own investigation. So, was is suicide? Was it murder? And who is 'he'? GENTLE MUSIC She was a fun-loving person. She was always happy, um, very vibrant. She was the one that made everyone laugh, motivated everyone and just got everyone up and going. Nadine Haag (33) was a healthy Kiwi woman chasing her dreams in Sydney ` dreams destroyed in the wake of a disastrous relationship. There was a note,... a cut wrist... and pills. It was here, in the Sydney suburb of Castle Hill, that Nadine Haag lived and died. When her body was found in the apartment block behind me, the police concluded suicide, but her family decided the NZer died differently. They suspect foul play. Nadine was not suicidal. She was not depressed. She was happy. She loved life. It didn't make sense. We were with her for three days, four days prior. We had just spent seven to 10 days with her celebrating her birthday, shopping, getting ready for Christmas. There was no reason for her to commit suicide. What's more, the family say they can back those suspicions with evidence they've turned up in their own inquiry ` evidence they claim was missed by the police. What do you think of the police handling of this investigation? Appalling. Hi, everyone. Originally from Dunedin, Nadine and her family migrated to Australia in the '90s. She'd always wanted to be a dancer on the stage. And it was as a dance instructor that she met Nestore Guizzone. He was the student and she was the teacher. She was madly in love with this man who said he was a pilot, a dive instructor. Oh, he was a very smooth talker. He promised to take her overseas to places that she loved like Paris, Italy. And that was something that really excited her, you know. She was happy. She was in love. She was in love. She was very much in love. A year later they moved to Sydney and Nadine gave birth to their daughter. It just went downhill. Quite the opposite to what he said. She confided her fears to her sister, Cherie. It was the verbal abuse, then the threats of violence and then the actual pushing her up against a wall and raising his fist to her and threatening to kick her out of the house. I just found all my diaries ` all of my diaries ` dating back to, like, 1990. Since she was a little girl, Nadine had kept diaries. Her final entries would be submitted as evidence at the inquest into her death. 'He towered above me with both fists raised at my face.' Nadine's diary would document Nestore's threats. '14th of March '09. He looked like he was going to kill me. Oh my God.' And then it got to a stage where she was absolutely petrified and knew she had to do something about it. He slammed his fist down and said 'You'll do as I say.' And I froze. Allegations later denied by Nestore. Nadine fled to Queensland. When she left him she was able to regain her confidence. She was able to become the person that she was before. She'd get back into her routine, which was exercising, she came up to Queensland to be with the family. But Nestore was back in Sydney, so Nadine was obliged to return to share parenting with him. I spoke to Nadine on December the 3rd at about 9.20. We had a 20 minute conversation, as we normally did every morning. And I knew of her plans for that day ` that she'd just dropped her daughter off to Nestore's mother, that she was going to go to the gym and that she had plans to go and see her lawyer at 2 o'clock that afternoon. She said to me that she was going to call me the minute she walked out of the lawyer's office, and she didn't. The next day Cherie and Nadine's lawyer raised the alarm. A fire crew broke into her flat. I got a phone call from the detective in charge, Julia Brown, informing me over the phone that Nadine had committed suicide. Did you accept that? Did you accept that? No. Nadine's body was discovered in the shower of her apartment. And at a glance the hallmarks of suicide were there ` empty pill packets, a slashed wrist and even a note written in her own hand. But her sisters say that for a woman who planned to take her own life, Nadine had simply too much to look forward to. She had plans within weeks to return to Queensland ` to the sun, to the surf, and to her own family. She would never do this sort of thing. There was no reason for her to commit suicide. Up next, a chilling message from Nadine ` 'he did it.' But who was 'he'? I had nothing to do with it. When Sydney police found Kiwi Nadine Haag's body in her shower, the family suspected foul play. Nadine was not suicidal. She was not depressed. But police stuck to the suicide theory. Backing their conclusion ` a razor, pills found at the scene, and this farewell note: 'I love you more than words can say. I love you, precious girl. 'Never stop loving. never stop living. Never stop.' To Nadine's family, those words, 'Never stop loving. Never stop living', carried a code ` yearning for life, not death. There was nothing in there to state that she wanted to give up life, that she wanted to commit suicide, she was over it, she was tired of this or that. She was happy, she loved life. She would never do this sort of thing. There was no reason for her to commit suicide. So they set up their own investigation. Everything they told us wasn't making sense to what we knew. Nadine's family would unearth clues the police had missed ` a dress that vanished, missing knives. Two knives from a set of six that were given to her only days beforehand, quite potentially could've been the implement used. the size and the depth of her` the wound was almost down to the bone, right across her wrist. It was very large. The nearest thing to a blade found at the scene ` a woman's safety razor. Could that have inflicted the wound on the wrist? Could that have inflicted the wound on the wrist? I don't believe it could have, no. Then the question ` did she die where the body was found? Now, as a nurse, what would you have expected to have seen if she'd cut her wrist in the shower? If there's an arterial cut, it should've` probably more likely have sprayed. The blood should've been all over the walls in the shower. And the fact that there was no blood around the shower. There was a lot more blood outside the shower. No background` No background information gathered at all. To the family, it's as if nothing adds up. The police said that she had an overdose, and there was no drugs in her system. So that's the toxicology report. The bruising on her body, how` it was explained that she acquired those not through self-defence, but she got them through slipping in a one-square-metre shower. That's some of the major, major issues. And the most sinister ` a message from the grave. Screwed up in the corner of the evidence bag, the family themselves found another piece of paper with a chilling message. Scrawled in the top corner were the words, 'He did it.' There's only one 'he' in Nadine's life, you know, and the words say it all ` he did it. I had nothing to do with it. That 'he', in the family's opinion, is Nadine's estranged partner Nestore Guizzone. What was the explanation from the detective? She had no idea. What she did say was 'OK, let's find out how he did it,' was her words at that time. When we came back from a break, she then said to us, perhaps he mentally made her do this. That was her explanation. In other words, did Nestore drive her to it? Two and a half years later, new occupants of Nadine's apartment found another message. Again, the words, 'He did it.' The location of that second note, which was inscribed on the wall outside the shower was actually covered by where a towel may have been hanging over, which is potentially why it was missed. So what does her ex-partner Nestore Guizzone make of all this? We asked for an interview. He refused to comment, however he did talk earlier to Channel 7 Australia's Ross Coulthart. The scribbled note saying he did it ` you know about that, don't you? No. No. Sorry, you don't know about the 'He did it' note? I heard that somebody wrote down on some tiles 'He did it' or something. what does it suggest to you ` the term 'He did it'? Well, it looks like that she's obviously... I` I've got no idea, mate. I'm not going to speculate. I'm definitely not going to get embroiled in a bunch of speculation for a media circus. I'm not going down that track. Why would Nadine write that? I'm not answering that. I told you I'm not going to speculate as to why people do and don't do the things they do. I'm not some sort of wizard who can read people's minds. So, could I be clear about this? Did you have anything to do with the death of Nadine Haag? No, not at all. Where were you on the day that Nadine died? Generally at home, working. Nadine's family say that's not supported by his phone records. Nestore's cell phone signal places him in Castle Hill for 6 hours. That's not what he recalls. I remember being home all day because I remember specific things that I was doing that day. I remember contacting work, being contacted, etc. So he says he doesn't remember being in Castle Hill, despite those phone records. So far, New South Wales police have resisted pressure to reopen the case, despite support from a private detective hired by the family ` a former detective inspector. The sheer lack of blood certainly alerted me to the fact that it wasn't what would have been a suicide where an artery had been cut. The tragedy is that she went to more effort in her last moments to try and identify the killer than the police have done in the last two years. I just find it hard that a leading detective from Victoria who's done over 900 suspicious deaths also seems to think that this is more than just a suicide. Just around the corner from Nadine's apartment is the local police station. Officers have declined to comment on the family's accusations, saying that Nadine's death was the subject of a coronial inquest. What we've had to do and what the police have done has just been... No family should have to go through that ` have to do the things that we've had to do. I believe that someone came to her apartment. I believe that she was beaten, that she was` the bruising on her body was defence wounds. I believe she was made to write a note. If it wasn't a suicide note, what was the message she was trying to convey? She wanted us to keep going. She wanted... for us never to give up,... cos we know. She left those words for a reason and she knows we know. The Coroner's now investigating the case, and the Haag family hope his verdict will force New South Wales police to reopen their investigations into Nadine's death. Well, next, Ken Barlow from TV's most famous street. He goes into bat for an embattled co-star. These girls who come ` they` they're sexually active, sexually mature. They don't ask for their birth certificate. They don't know what age they may be. They` They're certainly not grooming them an exploiting them, but they can be caught in this trap.

Coronation Street was only ever meant to run 13 episodes. 53 years later it's television's longest-running soap. Much has changed, but there's been one constant. That's William Roache, or Ken Barlow. Back in 1960, William Roache got 10 quid an episode. Now he gets 3000 pounds. Garth Bray on the street with William, AKA Ken. We could walk across here. I don't want to get us yelled at. I mean, I know you're a big star around here` I don't want to get us yelled at, either. William Roache portrays perhaps the most English man in England, and on his day off from being Ken Barlow, he's back on Coronation Street, calmly blowing the lid on the latest plot twist. We've just had a big fire in the Rover's. The Rover's has been totally gutted, and it's going to be remade. So this is way ahead. You won't get this` This is spoilers. This is the place he's lived most of his life, a cobblestoned cul de sac in the heart of Manchester full of familiar faces. My place of worship is the Rover's Return, and I'll swap brown ale for me and Booke any day. I love Coronation Street, and I have given 53 years of my life to it, and I do love it. I'm very proud of it. Why did you put the phone down on me? It's Ken. He knows. I told him everything. Ken, please. It's Ken. He knows. I told him everything. Ken, please. Shut up! ALL CLAMOUR Ken has got the most wonderful dysfunctional family you could possibly imagine. You know, his daughter's a murderess,... ROCK MUSIC ROCK MUSIC (GRUNTS) ... his son's an alcoholic bigamist, Well, here he is ` the husband. Ken and Deidre are a bit dodgy. You're always sorry! So he's got all that to deal with, so he's sort of wise into human frailties and things like that. What do you think has kept Ken going as a character, then, through all of that? Well, in the early days the problem was he was a university graduate, so what's he doing stuck in a little cobbled backwater? And how's our local genius then? And how's our local genius then? All right. I've not seen your name in paper recently. Haven't you been winning any more scholarships? He wants to help society. He wanted to be the voice of Wetherfield. His real weakness, of course, was his women. He's had these 25 girlfriends, 3 wives, but that doesn't mean he's a great wonderful lover and lothario, it just means he's pathetic at hanging on` hanging onto his women, or he picks the wrong ones. Look at the Rover's. You're not going to get in trouble for revealing all these little secrets? Perhaps the biggest secret is why, after more than 52 years, Coronation Street is still watched by many millions worldwide, and more than one in ten New Zealanders on any given week. We've got serials killers, rapes, you name it, going on. Who cancelled my wedding? Try anymore stunts like that and I'll will be booking your funeral. However, we are a moral show because, at the end of the day, you will find it sorts out. People get their comeuppance or whatever, bit like life. Arson attack or bad wiring, or...? We're not quite` the mystery is still a mystery. We're not quite` the mystery is still a mystery. Even you have no idea. I don't. I wasn't actually involved in it, but somebody dies. We won't say who, but somebody dies. Oh, they are filming here. 'Things are a little tense here on set,..' Better back off. Naughty boy! '... more than usual ` five units filming simultaneous scenes instead of the usual three. 'I'm told they may just be catching up after a Christmas break, but there could be another reason.' The Coronation St actor Michael Le Vell has appeared in court charged with 19 sexual offences against a child. On Valentine's Day, cast and fans of Corrie alike were shocked to learn one of the Street's famous faces had been arrested and charged with 19 child sex offences, including rape. Michael, you know everybody's innocent till they're proven guilty. Michael La Vell is free on bail, while Kevin the mechanic has been dropped from the plot until justice is done, maybe never to return. There's a very complex situation here that was stirred up by the Jimmy Savile business. Jimmy Savile was revered in life as a charity fundraiser. Now reviled in death as perhaps the country's most prolific paedophile. But just as Ken Barlow is never quick to condemn, William Roache is standing by his colleague of 30 years, even if the way he puts it might not do him any favours with some fans. Paedophilia is absolutely horrendous. Paedophiles should be sought out, rooted out and dealt with. But there's a fringe here, there's a fringe of people who, particularly pop singers, they have these groupies ` these girls ` who come, they're sexually active, sexually mature. They don't ask for their birth certificate. They don't know what age they may be, but they're certainly not grooming them and exploiting them, but they can be caught in this trap. These people are instantly stigmatised. Some will be innocent, some will not, but until such time as it's proven, there should be anonymity for both. If the facts are borne out, there are no excuses there Look, if` if` if someone has done something wrong, that` that will go to` the law will take its course. But even so, all of us, whatever, whether they're proven guilty or not, we should not be judgmental about anybody ever. We shouldn't go around condemning, unforgiving, we should always be totally forgiving about everything. We're well past Ken Barlow now. William Roache is in deep character as a new age spiritualist. If you accept that you are pure love, and if you know that you are pure love, and therefore live that pure love, these things won't happen to you. To some people that sounds perhaps like you're saying victims bring things on themselves. Is that what you're saying? No not quite, but, and yet, yes I am, in that we` everything that happens to us has been a result of what we have been in previous lives or whatever. Is Ken Barlow holding you back at this point? Is Ken Barlow holding you back at this point? No, on the contrary. I'm just Ken's caretaker. You could say I'm having two incarnations ` two for the price of one. So I'm very fond of Ken, and he's quite happy, but I am also. I'm mainly William Roache, and I'm here to live my life. If you could chose Ken's exit, how would you write the storyline? I'm not even gonna go there. I don't think about that. If you think about something, you bring it about. Let's not talk about it anymore then. If he goes it'll be because he's gone to his` he's gone home to the higher realms, as far as I can see. While I can do it, and while they want me I will be there, so I don't even think about that. It doesn't cross your mind at all. You just keep doing it. No and I'm not gonna let you cross my mind on that one, either. I want you to raise your glasses with me and drink a toast. To Coronation Street! CHEERING Gosh, he's in very good shape for 81. William Roche is headed out our way next week with his show Coronation Street on Stage. It crams 50 years of life on the Street into two hours.
