The bones were discovered by scenes of crime officers, forensic scientists and detectives during the 13-day search, which began on land off Stocking Fen Road in April. Experts have confirmed the bones are consistent with being human. A cold case called Operation Ongar was re-launched on April 10 by the Bedfordshire, Cambridgeshire and Hertfordshire Major Crime Unit to re-investigate the death of Andrew, who was last seen 25 years ago on Friday, September 28, 1990, at Factory Bank, off Great Whyte, Ramsey. This morning (June 17) a 64 year-old man from Ramsey was arrested at his home on suspicion of conspiracy to murder and has been taken to a Cambridgeshire police station. DCI Martin Brunning, who is leading the murder inquiry, said: The bones were discovered during a painstaking search of the area we had identified as being of interest. An expert in forensic anthropology has assisted the investigation and the bones will now subject to DNA testing and much more intrusive forensic analysis. Forensic processes have evolved significantly in the last 25 years. DCI Brunning said the re-launch of the investigation in April had already received an encouraging response from the public but the answers the inquiry was seeking still lie within the local community. He said: I want to bring anyone involved in Andrews death to justice and provide critical closure for his family, who have always desperately hoped for his return. Unsolved murder cases are never closed and we will leave no stone unturned. I am confident that local people have the additional information we need to provide Andrews family with the resolution they so rightly deserve, so I would urge anyone who thinks they can help us to come forward.
