Several people have come forward about a person known as Tommy, as part of a police investigation into the disappearance of Jane Furlong.
Ms Furlong disappeared from Auckland's Karangahape Rd in 1993 while working as a prostitute.
In May this year, a homicide investigation into the death of the 17-year-old was relaunched after her skeleton was found at Sunset Beach near Port Waikato.
As part of the investigation police were trying to find out the full identity of a man named 'Tommy', who could provide key information.
"Tommy is the name of the person that was inside Jane's diary on a date near about the time that she went missing that we believe or we have been told was a person that was looking to possibly hire Jane for a whole night,'' Detective Inspector Mark Benefield told Radio New Zealand.
