officer who first saw her said her feet and hands were clean, her fingernails manicured and not broken, and her fingertips free of blood, dirt or powder. There was no trace of lead dust. The rifle magazine would have been loaded at least twice during the killings; this would usually leave lubricant and material from the bullets on the hands. A scenes-of-crimes officer, Detective Constable Hammersley, said there were bloodstains on the back of her right hand but that otherwise her hands were clean. There was no blood on Sheila's feet or other debris, such as the sugar that was on the downstairs floor. Low traces of lead were found on her hands and forehead at post-mortem, but the levels were consistent with the everyday handling of things around the house. A forensic scientist, Brian Elliott, testified that if Sheila had loaded eighteen cartridges into a magazine he would expect to see more lead on her hands. The blood on her nightdress was consistent with her own, and no trace of firearm-discharge residue was on it. Given that Sheila was wearing just a nightdress, it was hard to see how she could have carried the cartridges. The rifle, without the silencer or sights attached, was lying on her body pointing up at her neck. June's Bible lay on the floor to the right of Sheila. It was normally kept in a bedside cupboard. June's fingerprints were on it, as were others that could not be identified, including one made by a child.

Detective Chief Inspector Thomas Jones, deputy head of CID, was so sure Sheila had killed her family that he ordered Jeremy's cousins out of his office when they asked him to consider whether Jeremy had set the whole thing up. The Daily Express reported on 8 August 1985, the day after the murders: A farming family affectionately dubbed "The Archers" was slaughtered in a bloodbath yesterday. Brandishing a gun taken from her father's collection, deranged divorcee Sheila Bamber, 28, first shot her twin six-year-old sons. She gunned down her father as he tried to phone for help. Then she murdered her mother before turning the automatic .22 rifle on herself. The result of this certainty was that the investigation was poorly conducted. The murder scene was not secured and searched thoroughly,
