"I feel it is important that the police are able to continue to investigate without speculation from anyone and I hope that the community will support me in this." The trio, including two men from Swindon aged 50 and 52, and a 52-year-old from Chippenham, are still being held on suspicion of kidnap and murder. Sally Ann's disappearance was initially classified as a missing person but police launched a murder investigation in 2014.
