Police are renewing their call for public information on the anniversary of the disappearance of Ian David Nichols, who was last seen at Lake Sorell (Tasmania) in 1989.
"This year marks 35 years since 51-year-old Ian Nichols went missing from the Dago Point area at Lake Sorell," said Detective Senior Sergeant Nick Bowden.
"At the time of his disappearance, Ian and a group of associates had gone to Lake Sorell to work on the construction of a retreat at Dago Point, on 14 September 1989. Ian had remained at the retreat site after his associates returned to Hobart, and he was later reported missing by his family."
In 2012 a coronial investigation was held regarding Ian's disappearance, with the coroner finding that he is presumed deceased.
"Based on investigations to date, it is believed that Ian died on or around 18 September 1989."
"We don't have clear answers in regard to Ian's disappearance and the circumstances of what occurred – it could have been misadventure; it could have been as a result of foul play or suspicious circumstances - our investigation remains open to all situations and scenarios."
"Understandably, Ian's disappearance was traumatic for his family and loved ones. Families always deserve answers to what happened to their loved ones, and we owe it to them to find those answers."
"Ian will remain listed as a missing person, the investigation will remain open, and we will investigate any new information received, until we find answers as to what happened to him."
"With the significant passage of time that has passed since Ian went missing, we hope that now is the time someone will come forward and provide information that helps us to determine what happened to him and provide closure for his loved ones."
"If you know anything about what happened to Ian - even if you think it may be insignificant - I ask you to come forward."
Information can be provided to Glenorchy CIB on 131 444 or through Crime Stoppers.
