Police investigating the murder of Auckland prostitute Jane Furlong believe a man by the name of Tommy could provide key information to the case.
A homicide investigation was launched in May after the skeleton of the 17-year-old was found at Port Waikato, 19 years after she went missing.
Detective Inspector Mark Benefield says Tommy is a name they discovered in her diary.
"Jane wrote in her diary a name of a person we believe was asking to hire Jane for a night. And we just want to try and make sure who that person is and see what his relationship was with Jane."
