Confirmation of the 24-year-old Georgia Bika from the findings of Swiss scientists at the Institute of Forensic Medicine, Toxicology and Chemistry in Bern. The 24-year-old had insisted on her complaint of a significant delay for the samples required for the toxicological tests.
The Swiss experts, in their conclusion, underline that the urine samples taken in Greece were more than 16 hours after the incident.
According to the scientists, during this period of time, the traces of alcohol could have disappeared, whereas if blood had been taken, the measurement would have been more accurate.
The document states, among other things, that the time of the «suspected incident» (rape) was at 04:30 on the morning of 1 January, while the urine sampling held at 21:00 on the same day, i.e. after 16 hours and 30 minutes.
The conclusion states the following:
«More than 16 hours passed between the suspected incident and the time the urine samples were taken. It is therefore likely that ethanol had been eliminated from the body, since the rate of elimination is between 0.1 and 0.2 grams per kilogram of ethanol per hour. Analysis of the samples showed high concentrations of the direct alcohol markers ethyl glucuronide (EtG) and ethyl sulphate (EtS), suggesting that a high amount of ethanol had previously been consumed, which may have resulted in a high blood alcohol concentration (above 0.8 gr per kg or higher).
The exact concentration of ethanol in the blood at the time of the event cannot be deduced from the EtG and EtS concentrations (as explained above) in the urine sample. For the theoretical calculation of blood alcohol concentration at a given time, the quantities of alcoholic beverages and the time of consumption must be known. Also, the time of the event, weight and height of the body must be known. If these data are known, then a theoretical calculation is possible.
Gamma-hydroxybutyric acid (GHB, «WATER EXTRACT») was not detectable in the urine sample sent.
Spectrometric screening - mass analysis (by high-resolution mass spectrometry) for drugs of abuse, drugs and xenobiotics (substances affecting physiological functions) did not reveal evidence of intake of exogenous substances other than caffeine, which was detected in addition to its major metabolites theobromine and theophylline in the urine sample.».
