Tuula was found bludgeoned to death in a field in St Clement on 31 December 1966 – but despite a major police investigation the case has remained unsolved.
The States police set up a cold-case team earlier this year to re-examine the initial inquiry, and have since received numerous new leads about her lifestyle.
Detective Inspector Lee Turner, who is leading the inquiry, said that more than 40 calls had been received since the case was reopened earlier this year but urged anyone else who thought they might have information to make contact with the police.
