army blanket and uniform had been confiscated at Godalming police station, and sent to a Dr. Roche Lynch at St Mary's Hospital to undergo Benzidine testing. Dr. Lynch was able to conclude that both the trousers and blanket had recently been washed in a basic and clumsy manner, and that each garment bore evidence of bloodstains. Furthermore, Lynch was able to deduce that the positioning of the bloodstains within the army blanket was consistent with where blood would have seeped from Wolfe's head and arm wounds, had she been wrapped in this garment. On 27 November 1942, a distinctive knife with a hooked point resembling a parrot's beak was discovered by a Private Albert Brown, hidden in a waste pipe within the wash-house at Witley barracks. Brown had discovered this instrument when tasked with clearing a blocked drain; he and a colleague immediately handed this knife to Harold Wade, who in turn forwarded the weapon to the Surrey Police. (Subsequent eyewitness testimony would indicate Sangret had excused himself to wash his hands in this wash-room on 12 October, immediately prior to his initial, informal questioning by Inspector Greeno. He had been alone in the wash-room for between three and four minutes, although the water had been cut off at the time.) The knife itself was not of Canadian issue, but British Army (although subsequent trial testimony would confirm such a model of knife had been issued to the Canadian Army until 1939). A Canadian soldier named Samuel Crowle had found this knife embedded in a tree close to one of the wigwams Sangret had earlier constructed in mid-August; he had intended to keep the knife due to its unique blade, but had been advised by a colleague to deliver it to a Corporal Thomas Harding, who had in turn handed the knife to Sangret on 26 August, suspecting the knife had belonged to him, given that Crowle had informed him he had found the knife near a wigwam "with some people talking inside". Dr. Lynch subjected the knife to similar testing to which he had previously subjected Sangret's army blanket and uniform, although this knife—having been immersed in a drainage system for over six weeks—bore no evidence of bloodstains, hair samples or fingerprints. Nonetheless, Doctors Eric Gardner and Keith Simpson each independently examined the weapon on 3 December and concluded only such a knife could have inflicted the wounds discovered
