A man who was arrested on suspicion of murder after the discovery of a woman's bones near the M5 has been ruled out as a suspect.
The 37-year-old went to Cheadle Heath police station, in Stockport, earlier, but Avon and Somerset Police said he had been eliminated from the inquiry.
Speaking from his home in Bradford-on-Avon, Wiltshire, Melanie's father Steve Hall said: "We are not really attaching any real importance to the arrest.
"On numerous occasions over the past 13 years we have had people come forward and confess and I think this is probably one of those occasions."
