The items were tested for blood and semen, and the hairs were examined. The tests 26 turned out negative for the presence of semen, but blood was found on several articles of clothing. The analysis of the blood found in item of evidence 1 (canvas trousers), 5 (white underpants) and 6 (beige 27 bra) was type “B” blood, while the blood found on item of evidence 3 (green towel) was type “A”.

Investigators observed no vehicle that fit the description given by the 29 anonymous informant. 52.
