The sexual offences constitute a very serious problem in the western world society and there are difficulties in estimating the incidence and spread of sexual abuse: the data available indicate clearly that many lives are affected by sex offenders. The aim of this pilot investigation was possible to verify the presence of indexes common in the production of drawings of the Human Figure (Machover, 1949) of thirteen sex offenders, prosecuted for sexual crimes, aged between 16 and 39 years. Were analyzed history data through Detection Grid (De Leo et al., 2004), with the aim of obtaining data descriptive of the sample design and the Human Figure (Machover, 1949). The main hypothesis of the study was not confirmed. It was suggested that might emerge in common indices produced by DFU 13 sex offenders taken into consideration, but that did not happen. The drawings reveal the characteristics that are present in most subjects and draw attention on specific aspects, but that will not allow us to give these indices to the category of sex offenders. Key words. Sex offenders, young sex offenders, history, drawing the human figure, sexual abuse.
