Christine Holdsworth spoke to Hallam FM after police released some new CCTV footage which they think could help with their investigation into her son, Simon's, murder.
He was found in a field in Hackenthorpe just before Christmas.
There was also a reconstruction and the footage was shown on Crimewatch.
