cotton trousers worn by the dead girl. The woollen fibres were of four colours black, white, a brownish green, and turquoise. There were a considerable number of fibres of the first three colours but only five turquoise coloured fibres. On the rope, he also found fibres of black wool, white wool and brownish green wool. At a later date the clothing removed from the premises of the accused was also examined by Mr. Edgley. He examined what appeared to be a dark coloured woollen sweater. However, under microscopical
examination he found that this woollen sweater was in fact made of black and white interwoven wool, the white wool being in its natural undyed colour and the black wool being dyed. He also found on it what he described as "foreign fibres" consisting of brownish green woollen fibres and turquoise
coloured fibres. The second woollen sweater he examined
was, in fact, made of brown and green wool. On it he found
black and white fibres. He expressed his opinion that the black and white woollen fibres found on the brown and green woollen sweater were as the result of what he described as
"cross-contamination with the dark coloured woollen sweater".
However, as the result of the examination carried out by Mr. Edgley he was of the opinion that the black wool, white (undyed) wool, brownish-green wool and turquoise coloured wool found on the clothing of the deceased were identical in colour with the woollen fibres found on the dark coloured woollen sweater taken from the quarters of the prisoner at Chung Hom Kok Road. On testing the quality of these fibres he was satisfied that the various coloured fibres found on the clothing worn by the deceased and the dark coloured sweater found in the possession of the accused were also identical in quality. He went on to say and I quote -
"I believe, as a result of my examination and
finding and comparing fibres from the victim's clothing and those from the suspect, that these findings show that contact had taken place between the suspect's sweater i.e. the dark coloured woollen sweater, and the clothing of the deceased."
