LH/1 Reference mouth swabs LH/25 Low vagina 1+2 From Gillian GIBBS LH/26 High vagina 1+2 CE/4 Wet+dry swabs of lower stomachOn 5 December 2017 the results of STR profiling tests performed on reference sample 32068722 were received. This profile was us. for use in the interpretation of any evidence in this case. From information supplied to rne by the Metropolitan Police Service, I further understand that this reference sample originat. from Goran ADDAL (date of birth: 12 January 1991).Purpose of Examination The purpose of my examination was to examine the swabs, from Gillian GIBBS for semen to assist in addressing wtlether or not Goran ADDAL had vaginal intercourse with Gillian GIBBS and ejaculated onto Ms GIBBS, legs as alleged.Technical Issues Semen Examination Semen is a mixture of seminal fluid and spermatozoa (although not all semen will contain spermatozoa). Items are screen. for seminal fluid by the use of a chemical test that detects acid phosphatase, a chemical found in serninal fluid. The presence of semen is then confirmed by a microscopic examination for spermatozoa.In conducting STR profiling tests of semen stains that are mixed with other body fluids, a separation procedure is carried out. This procedure is designed to concentrate the cell types other than spermatozoa into one fraction (epithelial fraction) and the spermatozoa into another fraction (serninal fraction).Examination and Results Reference profile 32068722 was used as the reference (STR) profile of Goran ADDAL. LH/1 (51565673) was used to determine the referen. profile of Gillian GIBBS.Items from Gillian GIBBS CE/4 Stomach swabs The above item consisted of two swabs. The swabs were examined for the presence of blood and semen. No blood was detected on the swabs. A trace amount of semen wasSignature.

A sample was submitted for STR profiling and a partial profile, the components of which matched the corresponding DNA components.

I have work. as a Forensic Scientist since 2005. My area of expertise is in the analysis of body fluids and the interpretation of DNA profiles.Laboratory Reference LAB-000123 Customer Reference: .321Circumstances of Case From inforrnation supplied to me by the Metropolitan Police Service, I understand that on the 7 July 2012. a male attended 1 Church Lane, London, home address of Gillian GIBBS. The male had vaginal intercourse with Ms GIBBS and ejaculated onto her stomach.The interpretation and conclusions I have drawn in this case are bas. on information provided to me by the police. Should this information change then I would need to reappraise the findings. If such a reappraisal were required, it would be rnore effective if carried out in advan. of any trial.Items Received On the 3 Decernber 2017, the following items were amongst those received from the Metropolitan Police Service in connection with this case:
CE/4 Stomach swabs The above item consisted of two swabs. The swabs were examined for the presence of n. No blood was detected on the swabs. A trace amount of semen was3 of 5 Sqnature Page 2 of 4Labora, reference: LAB-00123 Customer reference: 54321 Continuation of Statement by Laura HUGHdetected in a sample test. from the swabs. A sample was submitt. for STR profiling and a partial profile, the components of which matched the corresponding DNA components in the STR reference profile of Goran ADDAL was obtained, therefore the semen tested could have come frorn him. If the sernen was not from Goran ADDAL then it must have come from someone else with tie same STR profile and the match observed is coincidental. I have estimated the probability of obtaining this matching STF2 profile if the semen tested was not from Goran ADDAL but was from someone unrelated to him as less than 1 in 1 billion (a billion is a thousand million).LH/25 Low vaginal swabs LH/26 High vaginal swabs The above items each consisted of two swabs. The swabs were exarnined for the presence of blood a. sernen. No blood was detected on either set of swabs. A trace amount of sernen was detected in a sample tested from each set of swabs. A sarnple from each item was submitted separately for STR profiling and a full profile which matched that of Gillian GIBBS was obtained; therefore the DNA test. could have come from her. This is not unexpected as the swabs were recovered from her.InterpretationSemen that could have come from Goran ADD. was detect. in a sample tested from the stomach swabs, itern CEJ4. This result is what I rnight expect if Goran ADDAL ejaculated onto Gillian GIBBS. legs as alleged.I understand that Goran ADDAL stated ‘no comment’ in interview.Should an altemative explanation be put forward for the presence of semen which could have .rne from Goran ADDAL, these findings may be further evaluated. This evaluation would be more appropriate in advance of any trial.Signature.
