Abstract: | Data on 225 adult arsonists arrested in a metropolitan county over a four-year period were systematically gathered. In each case 83 variables related to the arsonist and the arson were examined. The presence or absence of a partner in crime clearly differentiated two groups of arsonists . Partner and solo arsonists are characterized by a different level of social functioning and a different burden of mental impairment and criminal history. By focusing on the partner variable, it also becomes clear that the characteristics of the offense are related to those of the offender. |
