The ex-policeman who accused a former traffic officer of burying the body of Mona Blades beneath a Kawerau property, prompting a new search, had told police the same man was linked to another infamous New Zealand cold case.
Further details of Tony Moller's allegations, which led police on a fruitless search for the long-missing body of Miss Blades beneath the former home of former traffic cop Derrick Hinton in early January, have been revealed on a website created by Mr Hinton's daughter Pauline Barratt as an attempt to debunk the theories.
Ms Barratt, an Auckland lawyer, has also threatened Mr Moller, who served as a sergeant in Kawerau for 10 years, with legal action if he does not formally apologise to her family.
Email correspondence between Mr Moller, police and others released under the Official Information Act showed Mr Moller also accused Mr Hinton, now dead, over the unsolved murder of 13-year-old Tracey Ann Patient, whose body was found in the bush of the Waitakere Ranges in January 1976.
It remains among the country's most high-profile cold cases, alongside the disappearance of 18-year-old Mona Blades, last seen getting into an orange Datsun 120Y stationwagon on the Napier-Taupo Rd on May 31, 1975.
