Comparing 133 presumable rape victims who underwent blood sampling after the event with 2446 alcoholized female traffic offenders it was found that both groups had a delinquency maximum between midnight and 2 a. m. and a delinquency minimum between 6 a. m. and 6 p. m. Most of the rape victims, however, were approximately 5 years younger than the traffic offenders, most of whom were about 25 years old. The time intervals between blood sampling and the event were longer in the case of the rape victims (4 to 20 hours) whereas most traffic offenders underwent blood sampling 1 to 2 hours after the event. At comparable maxima of the distribution curves of blood alcohol concentration (between 1.5% and 2%) that of the rape victims showed a shift to higher values. This is also illustrated by the mean values of blood alcohol concentration at the time of the event: the blood alcohol concentration of the rape victims was 2.24% and thus 0.45% higher than that of the traffic offenders, who averaged only 1.97%. The reason for this is probably to be seen in the different modes of back computation. By assigning 38 offenders to 35 victims it was possible to set up and compare 35 pairs. Comparing the blood alcohol concentrations of all 35 pairs it was found that the blood of the victims contained on average 0.4% more ethanol than the blood of the offenders (1.41% vs. 1.01%).
