The biological grandmother of missing boy William Tyrrell says removing New South Wales' most high-profile detective from the investigation was 'finally some good news' in the four-year search for her grandson. Natalie Norris did not mix her words when asked what she thought about Detective Chief Inspector Gary Jubelin being stood down from the investigation into William's disappearance, amid allegations of misconduct. 'He makes me so angry', Ms Norris said on Friday from her home on the NSW mid north coast. Detective Jubelin lead Strike Force Rosann - the squad set up to search for William - who went missing from his foster grandmother's home on the NSW mid north coast on September 12, 2014 while dressed in a Spiderman suit. Natalie Norris says the removal of the detective in charge of the search for her missing grandson William Tyrrell is 'good news' and says he has never spoken to her or kept her informed 'He's treated Karlie and Brendan (William's biological parents) like they don't matter, and they do (matter).' Ms Norris said she has never met Detective Jubelin, nor has she ever spoken to him, which she claims has added to her 'torment' during the time William has been missing. 'I know he speaks to the foster parents all the time and he keeps them informed with the investigation. But he's my grandson and I get told nothing.' 'The whole thing, the whole scenario disgusts me,' Ms Norris said of not being kept informed. NSW Police confirmed 'an internal investigation is currently underway' by Professional Standards Command into Detective Jubelin. Detective Jubelin told the ABC on Friday he 'strongly denies' any wrongdoing while leading the Tyrrell case, and will continue to work in the homicide unit.

He is also facing staff management allegations. Detective Jubelin is NSW most high-profile detective after he was portrayed in the 2012 season Underbelly: Badness. As a senior homicide investigator, Detective Jubelin has also worked on well-known cases including the death of Matthew Leveson who disappeared from a Sydney nightclub in 2007 and the Bowraville murders. 'All that's done is distract people,' Ms Norris said of Detective Jubelin's 'celebrity status'. Meanwhile, the parents of Mathew Leveson said if it wasn't for Detective Jubelin, they may never have their son's body back. 'Gary gets things down, he puts everything he has into the job,' Gary Leveson told The Daily Telegraph. Leonie Duroux, the sister-in-law of Clinton Speedy Duroux who was one of teenagers killed in Bowraville said Detective Jubelin as a man of integrity. "Our whole family are very upset for Gary," she told the ABC "He's very professional. He's always communicated with the families and kept them up to date with what's going on. He does his job and he doesn't give up." Police confirmed the inquest into William's 2014 disappearance will still go ahead later this month even with the investigation's lead detective out of the picture. 'The acting state coroner and counsel assisting have been briefed and the William Tyrrell inquest will proceed as planned,' police said. Detective Chief Inspector David Laidlaw has taken over as the lead investigator on the team, more than four years after William's disappearance. NSW Police confirmed 'an internal investigation is currently underway' by Professional Standards Command into Detective Jubelin Three-year-old William vanished on September 12, 2014, and few leads have emerged as to who took him and where since then, despite a $1 million reward. Detectives identified 700 persons of interest, gathered more than 4,000 pieces of evidence, received more than 15,000 tips, and conducted hundreds of interviews. Detective Jubelin took over in early 2015 and last year led a new three-week search of bushland near William's foster grandmother's home in Kendall near Port Macquarie. Ms Norris said she has never met Detective Jubelin, nor has she ever spoken to him, which she claims has added to her 'torment' during the time William has been missing 'I dare say that with the intense interest in William's disappearance that someone watching this now might be feeling very uncomfortable… I'd suggest you come to us before we come to you,' he said in June. This renewed appeal and large scale search yielded nothing of significance, but police still believe William could be alive. Counsel assisting the coroner, Gerard Craddock SC, last year told a directions hearing for the inquest it wasn't possible to conclude William was dead. 'The police investigation into his disappearance is ongoing and police are following active leads at present,' he said.

He was portrayed by actor Matt Nable in Underbelly: Badness in a series about the effort to bring down Perish. Detective Jubelin in 2017 admitted he was 'frustrated' that the William Tyrrell case was unsolved but vowed to carry on. He said William was in foster care and it was that, combined with the circumstances of his disappearance, that meant there was jurisdiction to hold an inquest. Deputy State Coroner Harriet Grahame also told the court William could be alive. 'It isn't presently possible to conclude that he is dead. [The inquest] will seek to determine if he is alive or dead,' she said. William's family made an emotional appeal on the fourth anniversary of his disappearance in September. 'Today marks four tragic years since we last saw little William. Four years of heartache and four years of endless tears for everyone who held him dear - not knowing where he is or what has happened to him,' they said. 'Today also marks the gift of unending love, hope and support from across Australia and around the globe.
