Autopsies The two bodies were transported to the Anatomy Department of the
University of Edinburgh, where they were first treated with
ether to prevent further decomposition and destroy all maggot infestation, then preserved in a
formalin solution before being reconstructed prior to Professors Glaister,
James Couper Brash, and
Sydney Smith conducting their formal autopsies. A further bundle containing human remains was discovered shortly after the two bodies had been transported to the University of Edinburgh; this bundle contained two human forearms, with hands attached. The
fingerprints had not been completely obliterated from the sole pair of hands found with the remains, and as such, investigators were able to obtain a complete set of fingerprints. To approximate the time of death of the victims, Dumfriesshire police requested the assistance of a
Glasgow-based
entomologist named
Alexander Mearns, who, using the then-fledgling techniques of
forensic entomology to identify the age of the maggots found upon the remains, studied the life cycle of the
pupae found upon the bodies in order to approximate a time of death of both victims. From his examination of the pupae found upon both sets of remains, Mearns conclusively determined the pupae had originated from a particular breed of
blowfly known as
Calliphora vicina, and that the maggots discovered on the remains had been laid in the immediate vicinity where they were discovered. Mearns deduced the remains could not have lain where they were discovered for less than 12 to 14days. This conclusion suggested the victims' bodies could not have been disposed of in the location they were found after 17September. From the
skull sutures on both bodies, Glaister and Smith were able to determine that one of the bodies was that of a woman aged about 30 to 55, probably between 35 and 45, and that the second body was that of a woman aged between 18 and 25, probably aged between 20 and 21 at the time of her murder. In reference to the
cause of death, the older woman had five stab wounds to the chest, several broken bones, and numerous bruises. In addition, her lungs were remarkably congested, and her
hyoid bone had been broken, indicating she had been strangled before the other injuries had been inflicted. The limbs and head of the second victim bore signs of excessive
blunt force trauma, indicating she had been extensively bludgeoned with an unknown instrument. Professors Glaister, Brash, and Smith further concluded the mutilation of the two bodies would have taken approximately eight hours to complete, and that the two bodies had been drained of both blood and
viscera at the time of their dismemberment.
Lancaster connection Several of the pages of the
Sunday Graphic in which the remains had been wrapped had been a souvenir edition of the newspaper which had been printed and circulated solely in the Morecambe and Lancaster area of England on 15September, strongly suggesting the two victims and/or their murderer lived in
North West England. As such,
Inspector Jeremiah Lynch of
Scotland Yard—who had been called in to assist the investigation at the request of the
Chief Constable of Dumfriesshire—focused his efforts on recent
missing persons reports filed within this section of England on or shortly after 15September. In addition, the fact several sections of the victims' remains had been discovered several hundred yards downstream on the banks of the Gardenholme Linn and the Annan River suggested a date on or prior to 19September as to when the remains had been thrown into the stream, as that had been the final date of heavy rainfall in the area and thus when the flow of water had been much greater than at the time of the victims' discovery. Furthermore, sections of the clothing in which the dismembered remains had been found were also distinctive, with unique factors such as repair patches beneath armpits upon a blouse, and knots used to tie a pair of distinctive child's
rompers, suggesting either or both of the victims may have borne children. Five days before the discovery of the human remains in Moffat, Ruxton had visited Lancaster police, claiming his wife had "once again" deserted him; he had earlier visited the Morecambe household of the parents of the family maid, Mary Jane Rogerson, claiming their daughter, having recently engaged in an affair with a local youth, had become pregnant and that his wife had agreed to discreetly take her away from their home to arrange an
abortion. As abortions were at that time illegal in Britain, Ruxton had urged the Rogersons not to contact the police. On 1 October the Rogersons visited Ruxton at his practice. On this occasion, he attempted to placate their fears for Mary Jane's safety by claiming both she and his wife had broken into his safe and stolen £30 before eloping from his household. Despite Ruxton's insistence on this occasion that his wife and Mary Jane would almost certainly return once they had spent the money, the fact Ruxton had now given the Rogersons contrary explanations as to why his wife and their daughter were missing from his household aroused their suspicions. As such, the following day, they filed a missing persons report with Morecambe police. (Ruxton himself would not visit Lancaster police to formally report his wife and maid as missing until 4October.)
Identification On 9 October Scottish police visited the Rogerson household and asked Mary Jane's parents if they were able to identify any sections of clothing in which the bodies had been wrapped: MrsRogerson immediately recognised a blouse with distinct patchwork repair beneath one armpit as having belonged to her daughter, whom they had last seen on Saturday 14September. MrsRogerson was unable to identify the pair of child's rompers shown to her, but suggested the police should show the garment to a friend of hers named Edith Holme, who lived in
Grange-over-Sands and with whom Isabella, Mary Jane, and the Ruxton children had briefly lodged earlier that year on a brief vacation to
Morecambe Bay. When MrsHolme saw the rompers, she immediately recognised them as a pair she had bought for one of the Ruxton children the previous summer. Conversing with his Lancashire counterpart, the Chief Constable of Dumfriesshire discovered that Mary Jane's employer, Ruxton, had informally reported his wife missing the previous month, and that the final confirmed sightings of Isabella alive by anyone other than Ruxton himself had been on the evening of 14September, when she had left her two sisters in Blackpool to return to her Lancaster home, having travelled to the seaside resort to view the Blackpool Illuminations. The same day that police identified several items of the clothing used to wrap the dismembered remains, Ruxton again visited the Lancaster police station; on this occasion, he burst into tears, complaining that local rumours had begun to circulate regarding the discoveries of the human remains in Scotland as being those of his wife and maid, and that these rumours were proving to be detrimental to both his medical practice and his general reputation. He then requested they conduct discreet enquiries to locate his wife and maid, before demanding police search his house to quash these rumours. Although Ruxton was placated by officers before being driven home, at this point he was considered the
prime suspect in the murders by all law enforcement personnel thus far involved in the investigation. Lancaster police had by this stage spoken to one of the Ruxtons' two charladies, Agnes Oxley, who confirmed to officers that on 15September, Ruxton had arrived at her home and informed her that it was unnecessary for her to work at his premises until the following day, and that when she had arrived at 2Dalton Square the following day, the house had been in a general state of shambles, with carpets removed, a pile of burned fabric-like material in the garden, and the bathtub extensively stained with a yellowish discolouration. Furthermore, Ruxton had specifically requested she clean the bathtub that day, before explaining to her that the reason his hand was bandaged was that he had jammed it in a door. Conversing with the Ruxtons' neighbours, Lancaster police also discovered that Ruxton had asked MrsHampshire and her husband to extensively clean his house in preparation for redecoration, explaining that he was unable to do so himself as he had badly cut his hand opening a tin of fruit several days earlier. He had also given the Hampshires several stained carpets and a suit, saying they could keep them if they washed them. ==Arrest==
