This master thesis consists of a theoretical and an empirical part and deals with the issue of girls' crime. The focus of the work will be on family, social, educational and physical reasons, so that possible deficiencies, which led to abnormal behaviour, can be explained. Introduction to the topic in the theoretical part of basic concepts such as "youth", "deviant behaviour", "crime" and "delinquency" is defined. Furthermore in Chapter 2 the Youth Criminal Law is presented and the objectives and functions are explained. Here different penalty measures and the diversion are pointed out. Following is a description of the crime situation in terms of youth crime, including a gender differentiation. In the following chapter the conditions are presented which can lead to abnormal behaviour. Furthermore the expectations of society to youth, the media and the consumption are discussed, which require a former independence of young people and can lead to an overload. Finally it also deals with that deviant or criminal behaviour has a function in society. In the last chapter of the theoretical part the different roles of men and women in society are discussed. Here the gender socialization and the double burden of women here are underlined.The empirical part of the master's thesis deals with a survey of women, which constitute a criminal youth behind them, to demonstrate girls? crime. Due to the investigation it can be said that the interview partners reported no well functioning parents' house during the child hood. Peculiar is especially the subject of the "missing mother". Even the theme "violence in the family" and "peer" turned out to be a distinctive feature associated with criminal behaviour.
