[Statistical evaluation of 60,000 blood alcohol values from 1964 to 1983. III. Multiple convictions]

Between the years 1964 and 1983, 59,226 blood samples with appropriate blood-alcohol concentrations (BAC greater than 0.1 g/kg) were investigated at the Institute for Forensic Medicine at the University of Tübingen. These originated from 47,416 different "culprits", of whom 38,851 (81.9%) were first offenders and 8,565 (18.1%) multiple offenders. The total number of crimes committed by the latter group reached as many as 13. There were fewer women amongst the recurring offenders, the maximum number of offences in this group was 4. The age of the multiple offenders at the time of their first brush with the law was lower than that of single culprits. Their blood-alcohol level at the first offence was similar to that of single offenders, however it increased slightly with each subsequent time. Homotropic traffic offenders were mainly only represented in the group with the lower crime rate. Most multiple offenders proved to be criminal delinquents who were frequently conspicuous not only for criminal--but also for criminal--and traffic violations. In about half the cases the time intervals between 2 offences was under 3 years.
