The officers were speaking to residents, handing out leaflets and putting up posters right across the town in a fresh appeal for information. Detective sergeant Gordon Blair from Cambridgeshire police said: We have always said that the information lies here, we still believe that today. We are still investigating and still continuing to pursue lines of enquiry. On this day, in 1990, Andrew was last seen in Factory Bank, off Great Whyte, Ramsey, in a light blue Ford Cortina estate car eating some takeaway food, possibly fish and chips. Detectives believe he was killed later that evening with a shotgun at a garage called Mongrel Cars, which no longer exists, in Ramsey. Detective Chief Inspector Martin Brunning, from the Bedfordshire, Cambridgeshire and Hertfordshire Major Crime Unit said: Today marks a quarter of century of bereavement for Andrews family and they are well overdue some answers. Police were looking to specifically talk to the older community that may have any information. People will have not come forward before, they may have not access to a mobile, or we may bump into somebody that will have something and think they will come forward and talk, added DS Blair. The renewal of the appeal to find information about Andrew has been given the backing of his family. DS Blair added: They support the investigation all they want is closure and want to know what happened to Andrew. Businesses are being urged to put posters up in their shop front to jog peoples memory and residents being asked to have faith in the work carried out my police. DCI Brunning said: Unsolved murder cases are never closed and we will be doing everything in our power to find a resolution and bring anyone involved in Andrews death to justice. In June, police announced they had discovered pieces of bone during a painstaking 13-day search on land off Stocking Fen Road, Ramsey, in April. Operation Ongar was re-launched on April 10 by the Bedfordshire, Cambridgeshire and Hertfordshire Major Crime Unit to re-investigate the death of Andrew. A 64-year-old man from Ramsey who was arrested on suspicion of conspiracy to murder has been bailed until Wednesday (September 30). Anyone with information should contact the Major Crime Unit on 01480 422791, email firstname.lastname@example.org, or call Crimestoppers, anonymously, on 0800 555111.
