8-01 227 evidence items were sampled or bagged. 30 of these were not analyzed.
8-02 From the remaining 197 evidence items, over 480 DNA and Y haplotype tests were prepared from liquids, solids or hairs. Many objects were sampled in multiple places.
8-03 Out of the over 480 DNA and Y haplotype tests, only 193 of these tests actually yielded DNA useful for comparison. (40%)
8-04 24 tests were from samples taken from Ms. Kercher’s body. Of these, 1 test yielded DNA compatible with Guede’s Y haplotype, 17 tests yielded DNA compatible with Ms. Kercher’s, and the remaining did not yield DNA useful for comparison.
8-05 11 tests were from samples taken from the exterior of the cottage. Of these, 2 tests yielded DNA compatible with an unknown female, 2 tests yielded cat DNA and the remainder did not yield useful DNA.
8-06 21 tests were from samples taken from the basement apartment at the cottage. Of these, 16 tests yielded cat blood, 2 tests yielded DNA compatible with an unknown male and the remaining did not yield DNA useful for comparison.
8-07 221 tests were from samples or items taken from the upper apartment at the cottage. Of these, 6 tests yielded DNA compatible with Guede’s DNA or Y haplotype, 82 tests yielded DNA compatible with Ms. Kercher’s DNA, 2 tests yielded DNA compatible with a mixture of Ms. Kercher’s and Guede’s DNA or Y haplotype (both tests from the same sample), 5 tests from 5 different samples yielded DNA compatible with a mixture of Ms. Kercher’s and Knox’s DNA, 2 tests yielded DNA compatible with a mixture of Ms. Kercher’s and Sollecito’s DNA or Y haplotype (both tests from the same sample), 4 tests yielded DNA compatible with Knox’s DNA, 1 test yielded DNA compatible with a mixture of Knox’s and Sollecito’s DNA, 2 tests yielded DNA compatible with an unknown female, 3 tests yielded DNA compatible with an unknown male and the remaining did not yield DNA useful for comparison.
8-08 4 tests were from samples taken (from bloodied tissue papers) found in the vicinity of the cottage, yielding DNA compatible with an unknown male or an unknown female.
8-09 16 tests were from samples taken from Sollecito’s car and no DNA useful for comparison was found.
8-10 102 tests were from samples taken from Sollecito’s apartment. Of these, 1 test yielded DNA compatible with Ms. Kercher’s DNA, 6 tests yielded DNA compatible only with Knox’s DNA, 7 tests yielded DNA compatible with a combination of Knox and Sollecito’s DNA, 7 tests yielded DNA compatible only with Sollecito’s DNA, 3 tests yielded DNA of 3 unknown males and the remaining did not yield DNA useful for comparison.
8-11 29 tests were from samples taken from Guede’s apartment. Of these, 14 tests yielded DNA compatible with Guede’s DNA and the remaining did not yield DNA useful for comparison.
8-12 6 tests were from samples taken from the pub Le Chic and no DNA useful for comparison was found.
8-13 50 tests were from samples taken from the defendants or defendant’s items during arrests or likely at the police station. Of these, 6 tests yielded DNA compatible only with Guede’s DNA, 8 tests yielded DNA compatible only with Knox’s DNA, 1 test yielded DNA compatible with a combination of Knox and Sollecito’s DNA, 2 tests yielded DNA compatible only with Lumumba’s DNA, 4 tests yielded DNA compatible only with Sollecito’s DNA, 1 test yielded DNA of an unknown male and the remaining did not yield DNA useful for comparison.
8-14 Of the 82 tests yielding DNA compatible with Ms. Kercher’s DNA at the cottage, 4 samples were taken from the corridor floor, 5 were taken from the kitchen/dining floor, 66 were taken from Ms. Kercher’s room and clothing, 1 was taken from the floor in Romanelli’s room and 6 were taken from the small bathroom.
8-15 17 tests yielded unmatchable DNA, with 6 tests yielding DNA compatible with 3 different females and 11 tests yielded DNA compatible with 7 different males. 13 of these samples were found in tissue paper outside the cottage and on cigarette butts in the ashtray in the cottage kitchen.
