A murder mystery sparked after a woman's remains were found on a building site is to appear on Crimewatch tonight.
Detectives hope the TV appeal will help identify the victim and lead to her killer being caught.
A skull and human bones were found on January 25 by builders working on a development in Manchester city centre, in an area known as Angel Meadow, between Angel Street, Dantzic Street and Miller Street.
Angel Meadow was a notorious Manchester slum in the 1800s, famously described by social reformer Friedrich Engels as "hell upon earth".
The remains were of a white woman aged 18 to 35, but it is not known how long the body had been there.
A post-mortem examination found the woman had a fractured jawbone, collarbone and neck.
Forensic tests have been carried out on a number of items recovered, including a distinctive pinafore, blue jumper and bra and a piece of blue carpet.
Detective Chief Inspector Jeff McMahon, of Greater Manchester Police, said: "We had a great response from the public following an initial appeal to identify this woman, and while we are reviewing all the information we have received, we are yet to have anyone come forward and offer a name as to who this woman might be.
"We know she suffered a violent death and I am determined to get justice for her and to ensure whoever is responsible does not get away with murder.
"This is going to be a lengthy and difficult investigation but I would reiterate my appeal to anyone who thinks they might know who this woman is or who has any information about the distinctive clothing to get in touch."
Anyone with information is asked to call the major incident team on 0161 856 5448, or the independent charity Crimestoppers, anonymously, on 0800 555111.
